[0014] Hereinafter, the present disclosure will be described based on a morphological example. The partition device of the present disclosure includes at least one partition member. First, the configuration of the partition member will be described.

[0015] 1. Partition member FIG. 1 is an external perspective view of a partition member 10 according to one embodiment installed as a part of a partition device, the left side of FIG. 2 shows a plan view (viewed from the Z direction) of a part of the partition member 10 (the part indicated by A in FIG. 1), and the right side of FIG. 2 shows a cross-sectional view taken along the line B-B of FIG. 2. The partition member 10 of the present disclosure can be installed in a building, a vehicle, a structure, etc., and can adjust the degree of transmission from a transparent state to a non-transparent state.

[0016] 1.1. Use of the partition member Here, the partition member 10 constituting the partition device is arranged to partition a space, and adjusts the transmission of light, air, droplets, and sound between one side and the other side with the partition member 10 interposed therebetween. Therefore, the location where the partition member 10 is arranged is not particularly limited, and it can partition the inside and outside of a building, the inside and outside of a vehicle, between adjacent indoor spaces, partitioning within an indoor space such as an intermediate partition (partition) arranged within a building or a vehicle, partitioning of a space installed outdoors (various dedicated booths and multipurpose booths), etc., partitioning in an outdoor space such as a veranda or a wall, etc. can be mentioned. In addition, as the arrangement sites of the partitions and intermediate partitions between the inside and outside, the inside and the outside, between adjacent indoor spaces, between adjacent outdoor spaces, etc. in the above-mentioned buildings, vehicles, spaces installed outdoors, etc., they can be appropriately arranged at one or more desired sites such as the wall surface, floor surface, or ceiling surface of these buildings, or a window, or a door. In addition, buildings include not only houses but also various types of buildings such as offices, stores, large commercial facilities, educational facilities, cultural and educational facilities, hospitals and welfare facilities, and accommodation facilities. On the other hand, vehicles include automobiles, railway vehicles, ships, airplanes, spacecraft, etc.

[0017] 1.2. Structure of the partition member In the figures shown below, for the sake of clarity, each member and each part constituting the partition member may be exaggerated, deformed, or omitted in the display. For the sake of clarity, only some of the repeated reference numerals are described, and it may be omitted to attach reference numerals to other parts. Also, for the sake of convenience, the directions of the so-called three-dimensional coordinate system (X, Y, Z) orthogonal to each other are represented in the drawings. In this embodiment, for the purpose of explanation based on the posture in which the partition member is installed, the X direction is the horizontal direction, the Y direction is the vertical direction, and the Z direction is the thickness direction. In addition, the directions in the X-Y plane may be referred to as the finding direction, and the Z direction may be referred to as the depth direction.

[0018] As can be seen from FIGS. 1 and 2, the partition member 10 is a plate-like member as a whole, has a plate-like main body 11, and a plurality of transmission portions 11a that transmit light and air in the thickness direction (Z direction in the figure) are provided in this main body 11. In this embodiment, the transmission portion 11a is constituted by a hole that penetrates the main body 11 in the thickness direction, and this hole is surrounded by a wall 11b that is a part of the main body 11. In this embodiment, the transmission portions 11a having a hexagonal shape in plan view are densely arranged in the XY plane in a so-called honeycomb structure. However, it is not necessarily required that the transmission portions 11a be densely arranged, and it is sufficient that a plurality of transmission portions 11a are arranged in the XY plane.

[0019] Also, the shape of the transparent portion 11a in plan view does not have to be hexagonal, and other geometric shapes may be used. The shape is illustrated in FIG. 3. The shape shown at the top of FIG. 3 is an example of a square, the shape shown in the center of FIG. 3 is an example of a circle, and the shape shown at the bottom of FIG. 3 is an example of a triangle. However, it is not limited to these examples. For example, if it is a quadrilateral, there are a rectangle, a rhombus, a parallelogram, etc., and in addition, an ellipse, a waveform, and an irregular geometric shape may also be used.

[0020] Also, the inner surface properties of the wall 11b constituting the transparent portion 11a can be appropriately set. For example, the daylighting efficiency can be improved by increasing the light reflectivity of the inner surface of the wall 11b. Conversely, the light shielding property can be enhanced by lowering the light reflectivity of the inner surface (for example, making it black). Also, by making the inner surface a rough surface, irregular reflection of light can be caused, thereby reducing the visibility on the opposite side or creating a unique design.

[0021] The material constituting the main body 11 is not particularly limited, and it is preferably a material that does not transmit light. Among them, it is preferably lightweight, such as metals such as aluminum and titanium, or alloys such as duralumin containing one or more of these metals, meta-aramid resins (as a product, there is Nomex (a trademark of E.I. du Pont) of E.I. du Pont), polyethylene, polypropylene, polyethylene terephthalate (PET), polyvinyl chloride (PVC), polycarbonate resin, acrylic resin, phenolic resin, urea resin, melamine resin, urethane resin, epoxy resin, etc., kraft paper, cardboard, paper such as glass woven fabric (glass cloth), glass non-woven fabric, woven fabric, or non-woven fabric, or those impregnated with one or more resins in any of paper, woven fabric, or non-woven fabric, and in the case of a curable resin, those obtained by curing the impregnated resin can be mentioned.

[0022] Furthermore, in the partition member 10 of this embodiment, end members 12 are arranged on the front and back surfaces (both ends in the thickness direction (Z direction)) of the main body 11. A diagram for explanation is shown in FIG. 4. The upper diagram shown in FIG. 4 is a plan view focusing on one transparent portion 11a, the central diagram shown in FIG. 4 is a cross-sectional view taken along the C-C arrow in FIG. 4, and the lower diagram shown in FIG. 4 is an enlarged view of the portion indicated by D in FIG. 4.

[0023] As can be seen from FIG. 4, in the partition member 10 of this embodiment, the end member 12 is arranged along the portion of the main body 11 that forms the edge of the transparent portion 11a. Thereby, an appearance peculiar to the partition member 10 can be imparted. Further, by arranging the end member 12 at the edge of the transparent portion 11a, functions such as protection of the edge and prevention of injury by touching the edge can also be obtained. In this embodiment, the end members 12 are arranged on both the front and back surfaces of the main body 11, but the present invention is not limited to this, and the end members 12 may be arranged on only one of the surfaces. Further, unlike this embodiment, if adjacent transparent portions 11a are separated and there is a flat main body portion between the adjacent transparent portions 11a, the end member 12 may be arranged only at the edge of the transparent portion 11a, or in addition to the edge, the end member 12 may also be arranged on the main body 11 of the flat portion.

[0024] The end member 12 only needs to be arranged at least at the edge of the transparent portion 11a of the main body 11. For example, in addition to the form in which the end member 12 is arranged only at the edge of the transparent portion 11a as in this embodiment, as shown in FIG. 5, the end member 12 may be configured by arranging a material inside the transparent portion 11a. FIG. 5 is a diagram from the same viewpoint as FIG. 4. The upper diagram shown in FIG. 5 is a plan view focusing on one transparent portion 11a, the central diagram shown in FIG. 5 is a cross-sectional view taken along the G-G arrow in FIG. 5, and the lower diagram shown in FIG. 5 is an enlarged view of the portion indicated by H in FIG. 5. In this aspect, since the material is also arranged inside the transparent portion 11a, the material is arranged at the edge of the transparent portion 11a to form the end member 12. FIG. 5 is an example in which the material is arranged along the surface of the wall 11b forming the transparent portion 11a.

[0025] The material constituting the end member 12 is not particularly limited, but a resin can be used. Examples of such resins include silicone resin, fluororesin, polycarbonate resin, polyester resin, acrylic resin, urethane resin, epoxy resin, and melamine resin. According to this, the resin is applied to the edge of the permeation part 11a in a state of a liquid composition such as a solution or dispersion, monomer or prepolymer, or a molten liquid (such as dip coating). After coating, when the liquid is a solution or dispersion, it can be solidified (cured) by drying the solvent (solvent) or dispersion medium to form the end member 12. When the liquid is a liquid composition of monomer or prepolymer, it can be solidified (cured) by crosslinking or polymerization reaction by heating, irradiation with ionizing radiation such as electron beam or ultraviolet ray, or action of moisture to form the end member 12. When the liquid is a heated melt, it can be solidified (cured) by cooling the melt to form the end member 12.

[0026] Also, from the viewpoint of contributing to the bonding with the surface material as described later, the resin can be composed of an adhesive. Examples of such adhesives include natural polymer adhesives such as starch and casein, vinyl adhesives such as polyvinyl acetate, acrylic adhesives, polyester adhesives, polyamide adhesives, thermoplastic resin adhesives such as polyurethane adhesives, and thermosetting resin adhesives such as epoxy resin.

[0027] Also, the partition member 10 is preferably configured as follows, for example. The opening area of each permeation part 11a (the area of the opening part of one permeation part 11a from the viewpoint of the upper view in FIG. 4) is preferably 4 mm 2 or more and 900 mm 2 or less. From the viewpoints of daylighting, ventilation, and droplet suppression, it is more preferably 40 mm 2 or more and 700 mm 2The following applies. The opening areas of the plurality of transmissive portions 11a included in the partition member 10 do not all have to be the same, and they may be intentionally changed beyond the error range (±5%). In this case, for example, the opening area may be changed continuously or stepwise from one end portion to the other end portion of the partition member in a plan view, or the opening areas of the respective transmissive portions 11a may be changed to give an irregular impression.

[0028] In each transmissive portion 11a, when viewed in a plan view as shown in the upper figure of FIG. 4, considering the shape of the opening portion, the center-of-gravity position G is defined, and the distance L between the positions facing each other through the center-of-gravity position G is preferably such that the shortest distance among them is 2 mm or more and 30 mm or less. From the viewpoint of the balance of daylighting, ventilation, and suppression of droplet diffusion, the more preferable shortest distance is 6 mm or more and 16 mm or less. Also, the shortest distance with respect to the longest distance among the distances is preferably 0.1 or more and 1.0 or less. From the viewpoint of the balance of daylighting, ventilation, and suppression of droplet diffusion, the more preferable shortest distance with respect to the longest distance among the distances is 0.5 or more and 1.0 or less.

[0029] The depth of the transmissive portion 11a indicated by T in FIG. 2 (the thickness of the partition member 10) is preferably 3 mm or more and 100 mm or less. From the viewpoint of the balance of daylighting, ventilation, and suppression of droplet diffusion, the more preferable depth is 5 mm or more and 20 mm or less.

[0030] Also, the expected angle θ shown in FIG. 4 is preferably 10° or more and 80° or less. Thereby, the visual field control on the opposite side across the partition member 10 becomes more prominent. From the viewpoint of the balance of daylighting, ventilation, and suppression of droplet diffusion, the more preferable expected angle is 25° or more and 70° or less. Here, the viewing angle θ is defined as follows. First, consider a cross-section in the thickness direction corresponding to the figure shown in the center of FIG. 4 at the portion of the above-described distance L where the distance is the shortest. Next, as shown in the figure in the center of FIG. 4, a diagonal line is defined such that the Y-direction positions are opposite between one end and the other end in the Z direction. In FIG. 4, two such lines can be obtained, one rising to the right and the other falling to the right. Among them, the smaller angle with respect to the line parallel to the Z direction (the line parallel to the thickness direction) is defined as the viewing angle θ.

[0031] The ratio of the total opening area of the transmission portions to the planar view area (length × width, size in the X direction × size in the Y direction) of the partition member is preferably 0.70 or more and 0.99 or less. From the viewpoint of the balance of daylighting, ventilation, and suppression of droplet diffusion, a more preferable ratio is 0.80 or more and 0.99 or less.

[0032] When there is regularity in the arrangement of the transmission portions 11a, the distance between adjacent transmission portions 11a of the same mode (for example, the pitch indicated by P in FIG. 2) is preferably 4 mm or more and 60 mm or less. From the viewpoint of the balance of daylighting, ventilation, and suppression of droplet diffusion, a more preferable distance is 10 mm or more and 40 mm or less.

[0033] According to the partition member 10 as described above, it acts as follows, for example. FIG. 6 shows a diagram for explanation. FIG. 6 is the same as the figure shown on the right side of FIG. 2, and the cross-section of the partition member 10 is shown.

[0034] When the partition member 10 is arranged as one of the constituent members of a partition device 100 to be described later (arranged vertically with the Y direction as the vertical direction), the line of sight from both sides across the partition member 10 (arrow S in FIG. 6) is restricted to a viewing angle from an angle close to the Z direction, and other lines of sight can be blocked, so the concealment is enhanced. Regarding light, light that enters at a large angle with respect to the Z direction is blocked in the same way as the line of sight, but light that enters at an angle close to being parallel to the Z direction passes through (arrow L1 in Fig. 8). Therefore, it is possible to selectively take in light that reaches particularly deep into the space, and it is possible to ensure daylighting performance. Here, if the inner surface of the wall 11b that constitutes the transmission part 11a is configured to have light reflectivity, reflected light can also be used for daylighting (arrow L2 in Fig. 8), and the incident light can be increased. On the other hand, when the inner surface of the wall 11a that constitutes the transmission part 11a is configured not to reflect light, light that enters at a large angle with respect to the Z direction is blocked. Such light is assumed to come from a position with a high solar altitude in the middle of summer, for example, and it causes the temperature of the indoor space to rise. Therefore, it is possible to block this light and improve the cooling efficiency.

[0035] In addition, since the transmission part 11a is configured to have a hole that penetrates the thickness direction of the main body 11, ventilation performance can also be ensured.

[0036] On the other hand, although the partition member 10 can transmit light and air in this way, the transmission of droplets can be greatly suppressed. The partition member can transmit air, so droplets also pass through. However, as a result of the inventor's intensive studies, it has been found that in particular, droplets generated from a person due to conversation, cough, sneeze, etc. can be effectively suppressed from passing through even in a state where air passes through according to the configuration of the partition member of the present disclosure. Therefore, according to the partition member of the present disclosure and the partition device including the same, it is possible to suppress the diffusion of droplets while having daylighting performance and ventilation performance. This is presumably because the particles of droplets generated from a person are relatively large as droplets and have a fast moving speed, and such droplets are difficult to pass through the transmission part of the partition member of the present disclosure.

[0037] In addition, the above-described partition member 10 may be disposed within a frame delimited by frame members. That is, one or more vertical frames (also referred to as vertical battens in this case) parallel to these (extending in the y direction) may be installed between a pair of vertical frames, or one or more horizontal frames (also referred to as horizontal battens in this case) parallel to these (extending in the x direction) may be installed between a pair of horizontal frames, or one or more of these vertical frames (vertical battens) and one or more of these horizontal frames (horizontal battens) may be installed between a pair of vertical frames and between a pair of horizontal frames, whereby the frame body 11 can also have a lattice-like partitioned structure in a plan view from the z direction. FIG. 7 shows, as an example, a partition member 10' in which three horizontal battens 14a are disposed between a pair of vertical frames 13, 13 and a pair of horizontal frames 14, 14, and one frame body is partitioned into four. And in such a frame body partitioned in a lattice shape, a partition member 10 having a structure as shown in FIGS. 1 to 6 can be installed for each lattice to obtain the partition member 10'.

[0038] In the partition member having a configuration in which the partition member 10 is installed in such a lattice-like partitioned frame body, the entire surface of the partition member is divided into a lattice shape, and the shielding amounts against light, air, and droplets can be adjusted individually for each lattice-like compartment. Therefore, it becomes possible to more finely and continuously increase or decrease the shielding amount of the partition member against light and the like.

[0039] 1.3. Antipathogenicity of the partition member In addition to the above configuration, the partition member 10 may have antipathogenicity. Thereby, the growth of microorganisms such as bacteria and pathogens such as viruses contained in droplets and adhering to the partition member 10 can be suppressed. The region where the partition member 10 should have such antipathogenicity is at least the surface of the region that attaches or captures droplets that may contain pathogens, that is, (A) the surface of the wall 11b inside the permeation part 11a in the main body 11, (B) the surface of the region other than the permeation part 11a in the main body 11, (C) the surface exposed outside the face material main bodies 22 and 32. shall be. For anti-pathogenic expression, it is preferable that all of these regions (A), (B), and (C) have anti-pathogenic properties. However, if it is possible to express the minimum anti-pathogenicity required for the partition member 10, anti-pathogenic properties may be provided in only any one of the regions (A), (B), and (C), or only any two of the regions. In order to provide anti-pathogenic properties to a predetermined region of the partition member 10, the partition member 10 may be configured to contain an anti-pathogenic agent described below inside the members themselves such as the main body 11 and the surface material main body 22 that make up the partition member 10, or a layer containing the anti-pathogenic agent described below may be laminated on the surface of these members by coating, bonding, or the like. Here, anti-pathogenicity means the property of reducing the pathogenicity of various pathogens. In addition, pathogens refer to various microorganisms such as bacteria, fungi (molds) such as filamentous fungi, various rickettsiae, protozoa (amoebae) such as amoebae, or microorganisms or things similar to microorganisms (in the case of viruses, there are both cases of classifying them as organisms and non-organisms) that can induce various diseases in the bodies of humans, animals, and plants (that is, have pathogenicity). Specifically, for example, it means the property of killing or damaging pathogens, suppressing their growth or cultivation, or suppressing the ability of microorganisms such as bacteria and pathogens such as viruses to infect or cause disease by some action. In particular, depending on the type of pathogen whose pathogenicity is to be reduced, it is called antiviral property when targeting viruses, antibacterial property when targeting bacteria, and mildew-proof (or anti-mildew) property when targeting molds, etc. In the present disclosure, "antibacterial property" refers to the property of reducing the pathogenicity of either or both of bacteria and fungi (molds). Specifically, it refers to the property of killing or damaging either or both of bacteria and fungi, or the property of continuously suppressing the growth and proliferation of either or both of bacteria and fungi, or the property of suppressing the ability of either or both of bacteria and fungi to cause infection or disease by some action or mechanism. Examples of bacteria include staphylococcus, Escherichia coli, Salmonella, Pseudomonas aeruginosa, Vibrio cholerae, Shigella, Bacillus anthracis, Mycobacterium tuberculosis, Clostridium botulinum, Clostridium tetani, and Streptococcus. Examples of fungi (or molds) include Trichophyton, Candida, and Aspergillus. In the present disclosure, "antiviral property" refers to the property of reducing the pathogenicity of a virus. Specifically, it refers to the property of inactivating a virus by denaturing the protein constituting the virus, the capsid of the virus, or the envelope, or by damaging the protein. Examples of viruses include norovirus, influenza virus, adenovirus, coronavirus, measles virus, rubella virus, hepatitis virus, herpes virus, and HIV. Regarding "antipathogenic property" here, it is difficult to uniformly define the action effect of the drug therefor. It varies depending on individual types of microorganisms such as the same kind of bacteria and viruses (strength of toxicity, strength of infectivity, etc.), and also depends on the environment such as temperature and humidity. In reality, which microorganisms such as bacteria or viruses the product suppresses the growth of depends on which microorganisms such as bacteria or viruses invade, and which microorganisms such as bacteria or viruses the product actually suppresses the growth of depends on the discretion of the user, and there are other such circumstances. Therefore, here, "antipathogenic property" is represented by a virus and evaluated using the antiviral activity value described later. Then, according to individual specific uses and the pathogens to be targeted, the type, content, and addition amount of the antipathogenic material that exhibits effective antipathogenic property against specific pathogens are selected.

[0040] In the partition member 10 having anti-pathogenicity, it is possible to impart a function of reducing troubles caused by microorganisms such as bacteria and viruses. Therefore, at least a partial region on the surface of the partition member 10 that contacts the outside world is imparted with anti-pathogenicity. From the viewpoint of anti-pathogenicity expression, preferably, anti-pathogenicity is imparted to the entire region on the surface of the partition member 10 that contacts the outside world.

[0041] In order to impart anti-pathogenicity to the surface of the partition member 10 that contacts the outside world, either of the following aspects (A) or (B) can be adopted.

[0042] (A) An anti-pathogenic agent-containing layer is laminated on at least one region, preferably the entire region, of the surface of the main body 11, the end member 12, and other constituent members (for example, facing materials, frames, handles, sashes, etc.) provided as necessary that contact the outside world of the partition member 10. Note that, as the surface of the main body 11 that contacts the outside world, the surface of the hollow transmission part 11a is also included. In addition, an anti-pathogenic agent-containing layer is laminated on the surface of the outermost layer that directly contacts the outside world of other constituent members provided as necessary.

[0043] (B) At least one region, preferably the entire region, of the main body 11, the end member 12, and other constituent members that constitute the partition member 10 itself is made to contain an anti-pathogenic agent inside. Note that since microorganisms such as bacteria and viruses adhere to the surfaces of these constituent members from the outside world, at least a part of the contained anti-pathogenic agent is contained so as to exist on the surface or near the surface of these constituent members.

[0044] Here, the anti-pathogenic agent means a substance having anti-pathogenicity as described above, and means a substance that reduces the pathogenicity of microorganisms such as bacteria or viruses. In particular, depending on the type of pathogen whose pathogenicity is to be reduced, it is called an antiviral agent targeting viruses, an antibacterial agent targeting bacteria, a mildew-proof agent (or an anti-mildew agent) targeting molds, etc. However, in the case of any agent, which pathogen each individual anti-pathogen agent can reduce the pathogenicity against and the degree of reduction if possible vary depending on the type of pathogen, environmental conditions, required level of anti-pathogenicity, etc., as described later, and also vary depending on the concentration (content) near the outermost surface of the anti-pathogen agent. Therefore, for example, even when a certain antiviral agent functions as an antiviral agent for a specific virus assumed under certain specific environmental conditions and at a certain assumed level of antiviral property, it does not necessarily function as an antiviral agent under unassumed viruses, unassumed environmental conditions, or an unassumed level of antiviral property. Conversely, an antiviral agent under a certain specific assumption may exhibit an effect of reducing the pathogenicity against pathogens other than viruses, for example, a specific bacterium, under specific environmental conditions and at a specific level of anti-pathogenicity. In this case, such an antiviral agent also functions as an antibacterial agent. And antiviral property means an antiviral activity value A measured and evaluated by the following method based on the method compliant with ISO21702 AV where A AV > 0.0. Preferably, A AV ≧ 1.0, and it is more preferable that A AV ≧ 2.0 or more.

[0045] The method for measuring the antiviral activity value is carried out as follows in accordance with ISO21702. Drop 0.4 ml of virus solution onto a 5 cm square test piece (antiviral processed product and unprocessed product), and cover it with a 4 cm square film. Leave this test piece standing at 25 °C for 24 hours, then wash and collect the virus on the test piece, and measure the virus infectious titer. Calculate the antiviral activity value A AV by the following formula (1). A AV = Ut - At (1) Here, A AV is the antiviral activity value, Ut is the virus infectious titer (PFU / cm 2) is the average of the common logarithms, and At is the virus infectivity titer (PFU / cm) after 24-hour standing of the antiviral processed product 2 ) and is the average of the common logarithms. In addition, after the antiviral agent inactivates the virus, it does not prevent inactivation of other pathogens such as bacteria and molds. Rather, it can be said to be preferable in that it can inactivate all pathogens that may exhibit pathogenicity. When a specific antiviral agent is also effective in reducing the pathogenicity of bacteria and molds, such a specific antiviral agent is also an antibacterial agent and an antifungal agent at the same time. Antibacterial properties are evaluated in accordance with ISO 22196 (JIS Z 2801).

[0046] By adopting the form of (A) or (B) above, the number of viruses captured, adhered to, or spontaneously invading and reaching the surface of the partition member 10 can be reduced, and troubles such as infections and diseases of humans, animals, and plants caused by the virus can be reduced. When antibacterial properties and antifungal properties are simultaneously expressed at the same time as the antiviral property is expressed, it is also possible to use it as a partition member 10 having antibacterial properties and an antifungal partition member 10, etc., and the pathogenicity of a plurality of types of microorganisms reaching the surface of the partition member 10 can be inactivated.

[0047] Generally, even for articles of the same material and layer structure, the correlation between the performance for each target pathogen of the anti-pathogenicity expressed, typically "antiviral property", "antibacterial property", "antifungal property", depends on the types of viruses, bacteria, and molds targeted, environmental conditions, the levels of antiviral property, antibacterial property, and antifungal property required, etc., and may be effective or ineffective. For this reason, depending on the type of bacteria, environmental conditions, and the level of antibacterial property required, it may be applicable not only to antiviral applications but also to antibacterial applications. Since mold is a type of fungus, the partition member 10 may also be applicable to antifungal applications depending on the type of mold, environmental conditions, and the level of antifungal property required.

[0048] The anti-pathogen agent-containing layer represented by the above (A) can be configured as a layer containing the anti-pathogen agent throughout the anti-pathogen agent-containing layer, a layer containing the anti-pathogen agent on the surface side of the anti-pathogen agent-containing layer in both the thickness direction and the in-plane direction, a layer containing the anti-pathogen agent on the surface side and the back side of the anti-pathogen agent-containing layer, a layer containing the anti-pathogen agent in a partial region in the in-plane direction on the surface side of the anti-pathogen agent-containing layer, or a layer containing the anti-pathogen agent in a partial region on the surface side and a partial region on the back side of the anti-pathogen agent-containing layer. In the anti-pathogen agent-containing layer, the location where the anti-pathogen agent exists is not particularly limited. However, from the viewpoint of enhancing anti-pathogenicity, it is preferable that the anti-pathogen agent is present in at least a partial region near the surface where the anti-pathogen agent-containing layer is exposed.

[0049] In this specification, the surface where the anti-pathogen agent-containing layer is exposed refers to the surface where the planar direction of the anti-pathogen agent-containing layer is exposed. Also, in this specification, the vicinity of the surface where the anti-pathogen agent-containing layer is exposed means the region within the range where the anti-pathogen agent is contained in the thickness direction from the surface where the anti-pathogen agent is exposed. That is, when using the radioactive compound (anti-pathogen agent) described later as the anti-pathogen agent, anti-pathogenicity can be exhibited even in a form where the anti-pathogen agent is absent on the surface of the anti-pathogen agent-containing layer and only exists inside the layer. However, in the form of using other anti-pathogen agents, the portion that surely exhibits anti-pathogenicity in the anti-pathogen agent-containing layer is the portion where the anti-pathogen agent is exposed to the outside from the anti-pathogen agent-containing layer. Therefore, at least one layer or more of the minimum units composed of anti-pathogen agent particles, atoms (including ionized ones), or molecules should exist on the surface of the anti-pathogen agent-containing layer. For example, when the anti-pathogen agent has an atom or a molecule as the minimum unit, a single atomic layer or a single molecular layer is sufficient, and when the anti-pathogen agent has a particle formed by a plurality of atoms or molecules aggregated as the minimum unit, only a single particle layer is sufficient. However, in reality, when forming the anti-pathogen agent as a single atomic layer, single molecular layer, or single particle layer in the anti-pathogen agent-containing layer, in addition to the difficulty in manufacturing technology, the anti-pathogen agent is likely to easily fall off or disappear due to external forces such as friction, resulting in the loss of the anti-pathogen function. There may also be viruses that penetrate into the anti-pathogen agent-containing layer from gaps between the anti-pathogen agent and the binder resin and the like. Furthermore, the anti-pathogen agent may have the property of migrating (bleeding) from the inside to the surface of the anti-pathogen agent-containing layer over time. In such a case, the atoms, molecules, or particles of the anti-pathogen agent are configured to form two or more layers on the surface of the anti-pathogen agent-containing layer, or the anti-pathogen agent is configured to be contained from the surface of the anti-pathogen agent-containing layer to the inside of the layer, and a part of the anti-pathogen agent is exposed from the surface of the anti-pathogen agent-containing layer. By adopting such a configuration, the anti-pathogen agent exposed on the surface layer exhibits anti-pathogenicity, and the anti-pathogen agent that has fallen off or disappeared from the surface of the anti-pathogen agent-containing layer over time is complemented by the anti-pathogen agent that has migrated from the inside, thereby suppressing the deterioration of the anti-pathogen function over time. Therefore, in reality, in the anti-pathogen agent-containing layer, it is configured such that atoms, molecules, or particles of the anti-pathogen agent are distributed over a depth of a predetermined thickness from the surface. The region where atoms and the like of the anti-pathogen agent are distributed over a depth of a predetermined thickness from the surface of such an anti-pathogen agent-containing layer is referred to as "the vicinity of the surface where the anti-pathogen agent-containing layer is exposed". Therefore, the thickness range of such "vicinity of the surface" may be appropriately designed according to the type of the anti-pathogen agent used, the formation method or manufacturing method of the anti-pathogen agent-containing layer in the anti-pathogenic partition member 10, the use of the anti-pathogenic partition device, the durability against friction, etc. of the anti-pathogen agent-containing layer. As the thickness of the vicinity of the surface of a typical anti-pathogen agent-containing layer, for example, a range of 1 μm or more and 5000 μm or less (provided that it does not exceed the thickness of the anti-pathogen agent-containing layer) is preferable, and in the case of normal uses, required durability, and the formation or manufacturing method of the anti-pathogen agent-containing layer, 3 μm or more and 100 μm or less is more preferable.

[0050] The anti-pathogen agent-containing layer needs to contain an anti-pathogen agent. The anti-pathogen agent-containing layer preferably contains an anti-pathogen agent and a binder resin.

[0051] Examples of the anti-pathogen agent include, as typical ones, "an anti-pathogen agent in which metal ions are supported or contained in a carrier", "particles of an imidazole compound", "particles containing a styrene polymer derivative compound and an unsaturated carboxylic acid derivative compound", "a copper-based anti-pathogen agent", "a zinc-based anti-pathogen agent", and "a radioactive compound". Hereinafter, "an anti-pathogen agent in which metal ions are supported or contained in a carrier" may be referred to as "anti-pathogen agent 1", "particles of an imidazole compound" may be referred to as "anti-pathogen agent 2", "particles containing a styrene polymer derivative compound and an unsaturated carboxylic acid derivative compound" may be referred to as "anti-pathogen agent 3", "a copper-based anti-pathogen agent" may be referred to as "anti-pathogen agent 4", "a zinc-based anti-pathogen agent" may be referred to as "anti-pathogen agent 5", and "a radioactive compound" may be referred to as "anti-pathogen agent 6".

[0052] From the viewpoint of enhancing the anti-pathogenicity, it is preferable that the anti-pathogen agent is present in at least a part of the region near the surface where the anti-pathogen agent-containing layer is exposed. By increasing the content of the anti-pathogen agent or adjusting the specific gravity of the anti-pathogen agent and the binder resin, it is easier to satisfy the above configuration.

[0053] Note that even if the anti-pathogen agent is buried in the anti-pathogen agent-containing layer, the anti-pathogenicity can be expressed by the following action. For example, atoms, ions, compound molecules, etc. having anti-pathogenicity such as silver ions are released from the anti-pathogen agent, or the anti-pathogen agent itself migrates (bleeds) from the inside of the anti-pathogen agent-containing layer to the surface, so that substances having anti-pathogenicity exist on the surface and in the vicinity of the surface of the anti-pathogen agent-containing layer, whereby the anti-pathogenicity can be expressed. Further, when the anti-pathogen agent is a radioactive compound, the anti-pathogenicity can be expressed by irradiating the surface of the anti-pathogen agent-containing layer with virus-killing radiation such as alpha rays and beta rays. Alternatively, the virus may penetrate (or invade) from the surface of the antimicrobial agent-containing layer to the interior near the surface through fine voids such as the gap between the antimicrobial agent and the binder resin interface, cracks in the antimicrobial agent-containing layer itself, and porous structures, and come into contact with the antimicrobial agent inside the antimicrobial agent-containing layer. In such a case, the antimicrobial agent inside the antimicrobial agent-containing layer can exhibit sufficient antimicrobial properties.

[0054] The antimicrobial agent 1 is an antimicrobial agent obtained by supporting or containing metal ions on a carrier. The metal ions of the antimicrobial agent 1 are preferably either silver or zinc, and more preferably contain both silver and zinc for discoloration suppression and cost reduction. Silver is superior in antimicrobial properties to zinc, but is costly and prone to discoloration due to oxidation. On the other hand, zinc can suppress the discoloration caused by the oxidation of silver. Therefore, by containing both silver and zinc, discoloration can be suppressed and the cost can be reduced. As the carrier of the antimicrobial agent 1, inorganic compounds such as zeolite, apatite, glass, molybdenum, zirconium phosphate, and titanium phosphate are preferable, and among them, porous inorganic compounds are preferable.

[0055] Zeolite is an aluminosilicate of an alkali metal or an alkaline earth metal, and both natural zeolite and synthetic zeolite can be used. Further, zeolite is classified into A-type, faujasite-type (X-type, Y-type), mordenite-type, clinoptilolite-type, etc. according to the crystal structure, and any of them can be used. Apatite is a general term for minerals having a composition represented by the following general formula. M 10 (ZO4)3X2 In the above formula, M represents Ca, Ba, Mg, Na, K, Fe, Al, etc., Z represents P, S, Si, As, etc., and X represents F, Cl, O, OH, etc. Representative examples corresponding to the above formula include fluorapatite "Ca 10 (PO4)6F2" and hydroxyapatite "Ca 10 (PO4)6(OH)2".

[0056] Examples of the glass include soda lime glass, borosilicate glass, lead glass, aluminosilicate glass, boric acid glass, and phosphoric acid glass.

[0057] As a method for supporting or containing metal ions on the carrier, a known method may be appropriately selected in consideration of the form and processing conditions of the anti-pathogen agent-containing layer, the required level of anti-pathogenicity, and the like. Here, "containing metal ions" means holding metal ions or a substance capable of generating metal ions in the carrier in some form. Further, the "substance capable of generating metal ions" means a substance that generates metal ions due to external factors or time-dependent factors, such as a substance that generates metal ions by dissolving in water or the like. Specific supporting or containing forms include a method of supporting by physical adsorption or chemical adsorption; a method of supporting by an ion exchange reaction; a method of supporting by a binder; a method of containing by implanting a silver compound into the carrier; a method of supporting or containing by forming a thin layer of a silver compound on the surface of the carrier by a thin film forming method such as vapor deposition, sol-gel precipitation reaction, sputtering; a method of ion-exchanging a metal oxide such as glass at a high temperature; and the like.

[0058] The anti-pathogen agent 1 is preferably in a particulate shape. Examples of the shape of the particles of the anti-pathogen agent 1 include spheres, ellipsoids, polyhedra, scales, etc., and there is no particular limitation.

[0059] The average particle diameter of the anti-pathogen agent 1 is preferably 0.1 μm or more and 10.0 μm or less, more preferably 0.5 μm or more and 5.0 μm or less, and even more preferably 1.0 μm or more and 4.0 μm or less. By setting the average particle diameter to 0.1 μm or more, the stability of the ink containing the anti-pathogen agent 1 can be easily obtained. Further, by setting the average particle diameter to 10.0 μm or less, it is easy to suppress appearance defects, deterioration of scratch resistance and stain resistance, and whitening of the coating film, and furthermore, it is easy to suppress wear of the members (coating roll, doctor blade, etc.) of the coating apparatus.

[0060] When the average particle diameter of the anti-pathogen agent 1 is defined as D1 and the thickness of the anti-pathogen agent-containing layer is defined as T, it is preferable that D1 / T is 1.0 or less, more preferably 0.7 or less, and even more preferably 0.5 or less. By setting D1 / T to 1.0 or less, it is easy to suppress the reduction of stain resistance and the whitening of the coating film, and furthermore, it is easy to suppress the wear of the members (coating roll, doctor blade, etc.) of the coating apparatus.

[0061] In this specification, the average particle diameter means the value measured as the mass average value d50 in the particle size distribution measurement by the laser light diffraction method.

[0062] The amount of metal ions in the anti-pathogen agent 1 is preferably 0.1 part by mass or more and 30.0 parts by mass or less, more preferably 0.5 part by mass or more and 25.0 parts by mass or less, and even more preferably 1.0 part by mass or more and 20.0 parts by mass or less with respect to 100 parts by mass of the carrier. Here, the "amount of metal ions" means both the supported metal ions and the contained metal ions. By setting the amount of metal ions to 0.1 part by mass or more, it is easy to improve the anti-pathogenicity. Also, by setting the amount of metal ions to 30.0 parts by mass or less, it is easy to suppress the discoloration by light.

[0063] The content of the anti-pathogen agent 1 is preferably 0.1 part by mass or more and 20.0 parts by mass or less, more preferably 0.5 part by mass or more and 17.0 parts by mass or less, and even more preferably 1.0 part by mass or more and 15.0 parts by mass or less with respect to 100 parts by mass of the binder resin. By setting the content of the anti-pathogen agent 1 to 0.1 part by mass or more, it is easy to improve the anti-pathogenicity. By setting the content of the anti-pathogen agent 1 to 20.0 parts by mass or less, discoloration due to light can be easily suppressed. Further, by setting the content of the anti-pathogen agent 1 to 20.0 parts by mass or less, a decrease in the physical properties of the coating film such as coating film strength and scratch resistance can be suppressed. Furthermore, by setting the content of the anti-pathogen agent 1 to 20.0 parts by mass or less, a decrease in stain resistance and whitening of the coating film can be easily suppressed, and furthermore, wear of the members (coating roll, doctor blade, etc.) of the coating apparatus can be easily suppressed. In addition, when the binder resin is a cured product of the curable resin composition, the content of the anti-pathogen agent 1 is preferably set to a relatively large amount within the above range.

[0064] The anti-pathogen agent 2 is particles of an imidazole compound. Generally, an imidazole-based compound is dissolved in an ink containing the imidazole-based compound. The reason for this is to uniformly diffuse the imidazole-based compound in an arbitrary layer and exert the effect of the imidazole-based compound throughout the layer. Therefore, in the usual method of using an imidazole-based compound, the imidazole-based compound does not exist in the form of particles in the anti-pathogen agent-containing layer. That is, in the present embodiment, it is characterized in that the imidazole-based compound maintains a particulate state.

[0065] The imidazole-based compound is a compound containing an imidazole skeleton as a structural unit of the molecule. In the present embodiment, among various imidazole-based compounds, those that maintain a particulate form in the anti-pathogen agent-containing layer can be used. Such imidazole-based compounds are preferably those that are difficult to dissolve in water and organic solvents. For example, methyl=benzimidazol-2-ylcarbamate (alias: carbendazim), polymerized imidazole-based compounds can be mentioned. Note that even methyl=benzimidazol-2-ylcarbamate (alias: carbendazim) and polymerized imidazole-based compounds may dissolve depending on the solvent, so care is required. For example, for methyl=benzimidazol-2-ylcarbamate (alias: carbendazim), it is preferable to use methyl ethyl ketone, ethyl acetate, etc. as the solvent.

[0066] The shape of the anti-pathogen agent 2 is not particularly limited, and examples include spheres, ellipsoids, polyhedrons, scale shapes, and the like.

[0067] The average particle size of the anti-pathogen agent 2 is preferably 0.1 μm or more and 10.0 μm or less, more preferably 0.2 μm or more and 8.0 μm or less, and even more preferably 0.3 μm or more and 7.0 μm or less. By setting the average particle size to 0.1 μm or more, the stability of the ink containing the anti-pathogen agent 2 is likely to be obtained. Further, by setting the average particle size to 10.0 μm or less, it is easy to suppress appearance defects, reduction in scratch resistance and stain resistance, and whitening of the coating film. The content of the anti-pathogen agent 2 is preferably 0.5 parts by mass or more and 20.0 parts by mass or less, more preferably 1.0 or more and 13.0 parts by mass or less, and even more preferably 3.0 parts by mass or more and 10.0 parts by mass or less with respect to 100 parts by mass of the binder resin. By setting the content of the anti-pathogen agent 2 to 0.5 parts by mass or more, the anti-pathogenicity can be easily improved. By setting the content of the anti-pathogen agent 2 to 20.0 parts by mass or less, a decrease in coating film physical properties such as coating film strength and scratch resistance can be suppressed. Further, by setting the content of the anti-pathogen agent 2 to 20.0 parts by mass or less, a decrease in stain resistance and whitening of the coating film can be easily suppressed.

[0068] The preferred range of the ratio D2 / T of the average particle size D2 of the anti-pathogen agent 2 to the thickness T of the anti-pathogen agent-containing layer and the preferred effects based thereon are the same as those in the case of the anti-pathogen agent 1.

[0069] The anti-pathogen agent 3 is particles containing a styrene polymer derivative compound and an unsaturated carboxylic acid derivative compound.

[0070] In this specification, the "particles containing a styrene polymer derivative compound and an unsaturated carboxylic acid derivative compound" may be "particles containing a styrene polymer derivative compound and an unsaturated carboxylic acid derivative compound", or may be "mixed particles of particles containing a styrene polymer derivative compound and particles containing an unsaturated carboxylic acid derivative compound", or may be a combination thereof.

[0071] The anti-pathogen agent 3 contains a styrene polymer derivative compound and an unsaturated carboxylic acid derivative compound. The constituent components of the styrene polymer derivative compound and the unsaturated carboxylic acid derivative compound preferably have at least one structure selected from the group consisting of styrene, sodium sulfonate, acrylic acid, maleic acid, and fumaric acid, and more preferably have both at least one structure of styrene and sodium sulfonate and at least one structure selected from the group consisting of acrylic acid, maleic acid, and fumaric acid.

[0072] The content ratio of the styrene polymer derivative compound and the unsaturated carboxylic acid derivative compound in the anti-pathogen agent 3 is not limited, but the mass ratio is preferably 30:70 to 70:30, and more preferably 40:60 to 60:40. When the anti-pathogen agent 3 is mixed particles of particles (particle A) containing a styrene polymer derivative compound and particles (particle B) containing an unsaturated carboxylic acid derivative compound, the mass ratio of particle A to particle B is preferably 30:70 to 70:30, and more preferably 40:60 to 60:40.

[0073] The reason why the anti-pathogen agent 3 exhibits anti-pathogenicity is not restricted by the mechanism speculated below, but is considered as follows. Influenza virus binds to the sugar chain receptor on the surface of host cells (the sugar chain terminus is neuraminic acid) and invades into the host cells. Since the copolymer containing styrene sulfonate has an ionic group similar to neuraminic acid, it is considered to bind to the virus instead of the host cell and capture the virus, thereby preventing the virus from binding to the receptor of the host cell and exerting an anti-pathogen effect. In addition, the unsaturated carboxylic acid derivative compound is considered to generate a hydroxyl group (OH - ) upon contact with water, and the hydroxyl group exerts an anti-pathogenic action.

[0074] The shape of the anti-pathogen agent 3 is not particularly limited, and examples include spheres, ellipsoids, polyhedrons, scale shapes, etc.

[0075] The average particle size of the anti-pathogen agent 3 is preferably 0.1 μm or more and 10.0 μm or less, more preferably 0.2 μm or more and 8.0 μm or less, and even more preferably 0.5 μm or more and 7.0 μm or less. By setting the average particle size to 0.1 μm or more, the stability of the ink containing the anti-pathogen agent 3 can be easily obtained. Further, by setting the average particle size to 10.0 μm or less, it is easy to suppress appearance defects, reduction in scratch resistance and stain resistance, and whitening of the coating film.

[0076] The content of the anti-pathogen agent 3 is preferably 0.5 parts by mass or more and 20.0 parts by mass or less, more preferably 0.5 parts by mass or more and 19.0 parts by mass or less, even more preferably 1.0 parts by mass or more and 17.0 parts by mass or less, and still more preferably 1.5 parts by mass or more and 15.0 parts by mass or less, based on 100 parts by mass of the binder resin. By setting the content of the anti-pathogen agent 3 to 0.5 parts by mass or more, the anti-pathogenic property can be easily improved. By setting the content of the anti-pathogen agent 3 to 20.0 parts by mass or less, a decrease in coating film physical properties such as coating film strength and scratch resistance can be suppressed. Further, by setting the content of the anti-pathogen agent 3 to 20.0 parts by mass or less, a decrease in stain resistance and whitening of the coating film can be easily suppressed. The preferred range of the ratio D3 / T of the average particle diameter D3 of the anti-pathogen agent 3 to the thickness T of the anti-pathogen agent-containing layer and the effects based thereon are the same as those of the anti-pathogen agent 1.

[0077] The anti-pathogen agent 4 is a copper-based anti-pathogen agent, and the anti-pathogen agent 5 is a zinc-based anti-pathogen agent. Examples of the copper-based anti-pathogen agent include cuprous oxide particles described in Japanese Patent No. 6145758 and copper iodide particles described in WO2010 / 026730. Examples of the zinc-based anti-pathogen agent include zinc-based inorganic additives described in Japanese Patent No. 6229429.

[0078] The anti-pathogen agent 6 is a radioactive compound. As the radioactive compound, in order to prevent adverse effects on health by radiation, a radioactive compound that emits either or both of α-rays and β-rays with relatively small flying distances in air or vacuum and permeability in various substances is preferable. Further, the radioactive compound preferably emits α-rays or / and β-rays with sufficient energy (quanta) to kill viruses and has a small radiation dose of radiation with high substance permeability such as γ-rays.

[0079] Examples of the radioactive compound that emits α-rays include 241Am, 243Am, 226Ra, 232Th, etc. Examples of the radioactive compound that emits β-rays include 147Pm, 210Po, 90Sr, 90Y, etc.

[0080] Examples of the binder resin include a thermoplastic resin and a cured product of a curable resin composition. The thermoplastic resin and the cured product of the curable resin composition may be mixed.

[0081] Examples of the thermoplastic resin include olefin resins such as polyethylene, polypropylene, polymethylpentene, ionomer, and various olefinic thermoplastic elastomers; vinyl chloride resins such as polyvinyl chloride, polyvinylidene chloride, and vinyl chloride-vinyl acetate copolymer; polyester resins such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, ethylene glycol-terephthalic acid-isophthalic acid copolymer, and polyester thermoplastic elastomers; acrylic resins such as poly(meth)acrylic acid methyl, poly(meth)acrylic acid ethyl, poly(meth)acrylic acid butyl, and (meth)acrylic acid methyl-(meth)acrylic acid butyl copolymer; polyamide resins typified by nylon 6 or nylon 66; cellulose resins such as triacetate cellulose, cellophane, and celluloid; styrene resins such as polystyrene, acrylonitrile-styrene copolymer, and acrylonitrile-butadiene-styrene copolymer (ABS); polyvinyl alcohol; ethylene-vinyl acetate copolymer; ethylene-vinyl alcohol copolymer; polycarbonate resin; urethane resin; polyarylate resin; polyimide resin; etc. Among these, acrylic resins are preferred.

[0082] Examples of the cured product of the curable resin composition include the cured product of a thermosetting resin composition or the cured product of an ionizing radiation-curable resin composition. Among them, the cured product of an ionizing radiation-curable resin composition is preferred from the viewpoints of scratch resistance and production efficiency.

[0083] A thermosetting resin composition is a composition containing at least a thermosetting resin and is a resin composition that cures by heating. Examples of the thermosetting resin include acrylic resin, urethane resin, phenol resin, urea melamine resin, epoxy resin, unsaturated polyester resin, silicone resin, etc. In addition to these thermosetting resins, a curing agent, a curing catalyst, etc. are added to the thermosetting resin composition as necessary.

[0084] The radiation-curable resin composition includes an electron beam-curable resin composition and an ultraviolet ray-curable resin composition as typical examples. Among these, from the viewpoints of less odor and difficulty in coloring because a polymerization initiator is not required, the electron beam-curable resin composition is preferable. Further, when the anti-pathogen agent-containing layer contains an ultraviolet absorber described later, the electron beam-curable resin composition is also preferable in that it is easier to increase the crosslinking density of the anti-pathogen agent-containing layer and easier to improve the scratch resistance and stain resistance.

[0085] The radiation-curable resin composition is a composition containing a compound having a radiation-curable functional group (hereinafter also referred to as a "radiation-curable compound"). The radiation-curable functional group is a group that crosslinks and cures by irradiation with radiation, and preferably includes functional groups having an ethylenic double bond such as a (meth)acryloyl group, a vinyl group, and an allyl group. Further, examples of the radiation-curable functional group include an epoxy group and an oxetanyl group. In the present specification, the (meth)acryloyl group means an acryloyl group or a methacryloyl group. Further, in the present specification, the (meth)acrylate means an acrylate or a methacrylate. Further, the radiation means those having energy quanta capable of polymerizing or crosslinking molecules among electromagnetic waves or charged particle beams. Usually, ultraviolet rays (UV) or electron beams (EB) are used, but other electromagnetic waves such as X-rays and γ-rays, and charged particle beams such as α-rays and ion beams are also included. Specifically, the radiation-curable compound can be appropriately selected and used from polymerizable monomers and polymerizable oligomers (sometimes referred to as "polymerizable prepolymers") that have been conventionally used as radiation-curable resins.

[0086] The radiation-curable compound is more preferably a compound having two or more ethylenically unsaturated bond groups, and among them, a polyfunctional (meth)acrylate-based compound having two or more ethylenically unsaturated bond groups is even more preferable. As the polyfunctional (meth)acrylate-based compound, either a monomer or an oligomer can be used.

[0087] Among polyfunctional (meth)acrylate compounds, examples of bifunctional (meth)acrylate monomers include ethylene glycol di(meth)acrylate, bisphenol A tetraethoxydiacrylate, bisphenol A tetrapropoxydiacrylate, 1,6-hexanediol diacrylate, and the like. Examples of trifunctional or higher (meth)acrylate monomers include trimethylolpropane tri(meth)acrylate, pentaerythritol tri(meth)acrylate, pentaerythritol tetra(meth)acrylate, dipentaerythritol hexa(meth)acrylate, dipentaerythritol tetra(meth)acrylate, isocyanuric acid-modified tri(meth)acrylate, and the like. Examples of polyfunctional (meth)acrylate oligomers include acrylate-based polymers such as urethane (meth)acrylate, epoxy (meth)acrylate, polyester (meth)acrylate, and polyether (meth)acrylate.

[0088] Urethane (meth)acrylate can be obtained, for example, by the reaction of a polyhydric alcohol and an organic diisocyanate with hydroxy (meth)acrylate.

[0089] Preferred epoxy (meth)acrylates are (meth)acrylates obtained by reacting trifunctional or higher aromatic epoxy resins, alicyclic epoxy resins, aliphatic epoxy resins, etc. with (meth)acrylic acid, (meth)acrylates obtained by reacting bifunctional or higher aromatic epoxy resins, alicyclic epoxy resins, aliphatic epoxy resins, etc. with polybasic acids and (meth)acrylic acid, and (meth)acrylates obtained by reacting bifunctional or higher aromatic epoxy resins, alicyclic epoxy resins, aliphatic epoxy resins, etc. with phenols and (meth)acrylic acid.

[0090] The above radiation-curable resin can be used alone or in combination of two or more.

[0091] When the ionizing radiation curable compound is an ultraviolet curable compound, the ionizing radiation curable resin composition preferably contains additives such as a photopolymerization initiator and a photopolymerization accelerator. Examples of the photopolymerization initiator include one or more selected from acetophenone, benzophenone, α-hydroxyalkylphenone, Michler's ketone, benzoin, benzyldimethyl ketal, benzoyl benzoate, α-acyl oxime ester, thioxanthones, and the like. In addition, the photopolymerization accelerator can reduce the polymerization inhibition by air during curing and increase the curing rate. Examples thereof include one or more selected from isoamyl p-dimethylaminobenzoate, ethyl p-dimethylaminobenzoate, and the like.

[0092] The pathogen agent-containing layer may contain additives such as an antioxidant, a light stabilizer, an ultraviolet absorber, a matting agent, and a colorant.

[0093] From the viewpoint of the balance between processing characteristics and scratch resistance, the thickness of the pathogen agent-containing layer can be, for example, 1.0 μm or more and 10000 μm (1 cm) or less. When the pathogen-resistant partition member 10 is composed of a single layer of the pathogen agent-containing layer, it is preferable to make the thickness of the pathogen agent-containing layer thicker. In the case of a single layer, the thickness of the pathogen agent-containing layer is preferably 1.0 μm or more and 10000 μm or less, more preferably 10 μm or more and 5000 μm or less. On the other hand, when the partition member 10 has a form having the base material 22, the decorative material 23, or both of them, considering that the self-supporting property and the durability against external force are borne by the base material, the anti-pathogenic effect is saturated if the thickness is above a certain level, and the processability decreases as the thickness of the pathogen agent-containing layer increases, etc., the thickness of the antiviral agent-containing layer is preferably a thin film. In the case of a form having a base material, from the viewpoint of the balance between processing characteristics and scratch resistance, the thickness of the pathogen agent-containing layer is preferably 1.5 μm or more and 30 μm or less, more preferably 2 μm or more and 20 μm or less, and even more preferably 3 μm or more and 15 μm or less.

[0094] 1.4. Other forms of partition members Fig. 8 shows an external perspective view of the partition member 20 according to another form, Fig. 10 shows an exploded perspective view thereof, and Fig. 10 shows a plan view (viewed from the Z direction). As can be seen from these figures, the partition member 20 of this form has a core material 10a having the same configuration as the above-described partition member 10 and facing materials 21 disposed on the front and back thereof.

[0095] The core material 10a can use the above-described partition member 10. Further, instead of the partition member 10, the core material 10a may be composed only of the main body 11 and the transmission portion 11a without including the end member 12 provided in the partition member 10.

[0096] The facing material 21 is a thin plate-like member and includes a plate-like facing material main body 22 and a plurality of holes 22a provided in the facing material main body 22. The opening area of one hole 22a is 5 mm 2 or more and 2000 mm 2 or less. Among them, from the viewpoints of lighting, ventilation, suppression of droplets, and design for reducing the impression of the holes 22a, it is preferably 7 mm 2 or more and 710 mm 2 or less. Further, from the viewpoint of making it difficult to touch the transmission portion 11a with a finger, it is more preferably that the opening area is 100 mm 2 or less.

[0097] In this form, as can be seen from Fig. 10, one hole 22a has a size such that a plurality of transmission portions 11a of the core material 10a are included (a plurality of transmission portions 11a are exposed) in the plan view (viewpoint from the Z direction, the viewpoint of Fig. 10) of the facing material 21. However, it is not limited to this. As shown in an enlarged partial view in Fig. 11, the number of transmission portions 11a visible from one hole 22a in the plan view may be less than one (for example, only a part of each of the adjacent transmission portions 11a is visible, and the form in which the wall 11b and the end member 12 cross the hole 22a).

[0098] The shape of the hole 22a is not particularly limited and can be appropriately set from viewpoints such as assumed line-of-sight control, daylighting, ventilation, suppression of droplet diffusion, and design. In addition to being circular as in this embodiment, it can take various forms such as polygons like triangles, quadrilaterals (squares, rectangles, rhombuses, parallelograms, etc.), pentagons, hexagons, etc., various geometric shapes such as ellipses, oblongs, waveforms, cardioids (heart shapes), asteroids (star shapes), and shapes modeled after letters, hiragana, katakana, Chinese characters, and any other form.

[0099] Regarding the pitch of the holes 22a, the number of holes arranged, the aperture ratio (expressed as a percentage of the area occupied by the holes in the main body of the facing material), etc., they can also be appropriately set from viewpoints such as assumed line-of-sight control, daylighting, ventilation, suppression of droplet diffusion, and design.

[0100] The material constituting such a facing material is not particularly limited, but it is preferably selected from the viewpoint of ensuring the strength of the partition member 20. For example, various metals such as aluminum, titanium, iron, copper, or alloys such as duralumin and stainless steel containing one or more of these metals, ceramics such as glass and porcelain, and resins such as silicone resin, fluororesin, polycarbonate resin, polyester resin, acrylic resin, and polyvinyl chloride can be appropriately used as needed.

[0101] The thickness of the facing material is not particularly limited either, but it is preferably thin from the viewpoint of reducing the weight of the partition member 20. Specifically, it is preferably 0.1 mm or more and 10 mm or less, and more preferably 0.3 mm or more and 5.0 mm or less. Also, the ratio of the total opening area of the transparent portions of the partition member as represented in a plan view to the plan view area (length × width, size in the X direction × size in the Y direction) of the partition member is preferably 0.20 or more and 0.70 or less.

[0102] In addition, in this embodiment, the facing members 21 are arranged on both the front and back surfaces of the core material 10a, but either one of them may be used. When the facing members 21 are arranged on both the front and back surfaces, it is preferable that at least a part of the positions of the holes 22a coincide in the plane (within the xy plane) with both facing members 21. Thereby, light and air can pass through the partition member 20 through the holes 22a. The transmission of light, air, and droplets at this time is controlled as described for the partition member 10 above, and the above effects are achieved. In addition, when the facing member is arranged only on one surface of the core material 10a, it is preferable to provide the end member 12 on the surface of the core material 10a on the side where the facing member is not provided from the viewpoint of preventing damage.

[0103] The method of joining the core material 10a and the facing member 21 is not particularly limited and can be performed by a known method. For example, the core material 10a and the facing member 21 can be fixed by a single frame body, or a combination of bolts and nuts can be used. In addition, when providing the end member, if the core material 10a is provided with the end member 12 and this end member 12 is made of an adhesive, this adhesive can be used for joining with the facing member 21, and adhesion can be achieved thereby.

[0104] According to the partition member 20 as described above, while having the effects of the partition member 10 described above, it has excellent design properties, and for example, it can produce a sense of unity with the space or create a characteristic space.

[0105] Figs. 12 and 13 show diagrams for explaining a partition member 30 according to another exemplary embodiment. Fig. 12 is an external perspective view of the partition member 30, and Fig. 13 is an exploded perspective view of the partition member 30. The partition member 20 is in a form in which the facing members 21 are arranged on both surfaces of a single plate-shaped core material 10a, whereas the partition member 30 has a plurality of holes 32a provided in a single facing member main body 32, and the core materials 10a formed small are fitted and arranged in each of the plurality of holes 32a. Such a partition member 30 also exhibits the same effects.

[0106] Still, the following can also be cited as yet another form of the partition member. In the partition member 20, a hole 22a is provided in the facing material 21, so that a part of the core material 10a is exposed, and light and air controlled by the core material 10a can pass through here, and the diffusion of droplets can be suppressed. On the other hand, in yet another form of the partition member, a plurality of facing materials are arranged on at least one surface side of the core material 10a, and the portion where the facing material is not arranged becomes a region, and this acts in the same way as the hole 22a to expose a part of the core material 10a, and light and air controlled by the core material 10a can pass through here, and the diffusion of droplets can be suppressed. Such yet another form of the partition member also has the same effect.

[0107] In this case, when a plurality of facing materials are arranged on each of the front and back surfaces, it is preferable that the positions of the regions on both surfaces coincide in the plane (within the xy plane) at least in part. Thereby, light and air can pass through the partition member through the region, and the diffusion of droplets can be suppressed.

[0108] Note that a facing material 21a may be arranged on one surface of the core material 10a, and a region formed by a plurality of facing materials may be formed on the other surface. Also in this case, it is preferable that the positions of the hole 22a and the region coincide (within the XY plane) at least in part.

[0109] The partition members in the above examples are each composed of one partition member, but two partition members may be stacked in the thickness direction and configured to move relatively in the X direction or the Y direction. Thereby, if the positions of the holes in the facing materials of the two partition members are overlapped in the thickness direction, light can pass through, and if the positions of the holes of the two are shifted, light can be blocked, so that the transmission and blocking of light can be switched.

[0110] 2. Partition device The partitioning device includes at least one of the above-described partitioning members and is configured to partition a space by a plurality of members. Examples of components other than the partitioning members include partition plates, walls, and the like. Here, for convenience, components other than the partitioning members are referred to as "partitioning elements".

[0111] The partitioning elements are not particularly limited, and as long as they can partition a space into one side and the other side regardless of whether it is indoors or outdoors, they are not particularly limited and known ones can be applied. For example, partition plates, doors, shoji screens, screen doors, windows, walls, fences, gates, etc. can be mentioned.

[0112] Also, the object where the partitioning device is disposed is not particularly limited, and it can be applied to buildings, vehicles, various facilities, etc. For example, as buildings, various buildings such as houses, offices, hospitals, stores, large commercial facilities, etc. can be mentioned. On the other hand, as vehicles, automobiles, railway vehicles, ships, airplanes, spacecraft, etc. can be mentioned.

[0113] For example, partitioning between the interior and exterior of a building, partitioning between the interior and exterior of a vehicle, partitioning between adjacent indoor spaces, partitioning within an indoor space such as an interior partition (partition) arranged in a building or a vehicle, partitioning of a space installed outdoors (a space partitioned such as various dedicated booths and multi-purpose booths), partitioning in an outdoor space such as a veranda and a fence, etc. can be mentioned.

[0114] As described above, the partitioning device has a wide variety of application locations and exhibits its effects in various places. That is, in the space partitioned by the partitioning device, the transmission of light, air, and droplets can be adjusted, and while having good daylighting and ventilation properties, the transmission and diffusion of droplets can be suppressed.

[0115] Since the partitioning device can be applied to various places, it is difficult to list all the morphological examples. However, for the sake of clarity, typical morphological examples of the partitioning device are listed and described below. Figure 14 is the first morphological example, and Figure 15 is the second morphological example.

[0116] 2.1. First Embodiment The partition device 100 according to the first embodiment is an example applied to one space formed in a house, a building, or the like. In this embodiment, a rectangular parallelepiped framework 1 is formed by combining beams (horizontal members) and columns (vertical members), and six frames surrounded by the beams and columns are formed. The partition device 100 is applied to the frames 1a to 1d that constitute the side portions of the framework 1 with respect to a structure in which a ceiling board 2 is arranged in the upper frame and a floor material 3 is arranged in the lower frame.

[0117] FIG. 14 is a diagram for explaining the partition device 100 of the first embodiment and is represented as an exploded perspective view. In the partition device 100 of this embodiment, two partition members 10, a wall panel (partition element) 101, and a door body (partition element) 102 are arranged side by side in the horizontal direction within one of the four frames, i.e., frame 1a. Within the frame 1b facing this frame 1a, two partition members 10, a window member (partition element) 103, and a wall panel 101 are arranged side by side in the horizontal direction. In this embodiment, the two partition members 10 are arranged so as to face each other.

[0118] It is arranged between frame 1a and frame 1b, and in the two opposing frames 1c and 1d, a partition member 10 is arranged in frame 1c and a wall panel (partition element) 101 is arranged in frame 1d. At this time, in this embodiment, the partition member 10 is arranged on the 1c side, which is the frame close to the partition member 10 arranged in frame 1a and the partition member 10 arranged in frame 1b. As a result, the partition member 10c has a sense of unity and is visually recognized, which is effective from the viewpoints of design and light effects.

[0119] 2.2. Second Embodiment The partition device 110 according to the second embodiment is an example in which a space surrounded by a plurality of partition members 10 arranged so as to stand on the floor surface in the case of indoors or on the ground in the case of outdoors is formed. In this embodiment, the partition members 10 are arranged on the plate-shaped base 111 and are arranged in a four-square shape with intervals. According to such a partitioning device 110, it is possible to function as a so-called booth that uses the partitioned space as a space having a predetermined purpose. Examples of the predetermined purpose include for meetings, for smoking, for individual workspaces, and the like.

[0120] Such a partitioning device 110 may be provided indoors or outdoors.

[0121] 2.3. Others In the above-described partitioning devices 100 and 110, a plurality of partitioning members 10 are arranged. However, in the partitioning device of the present disclosure, at least one partitioning member may be provided to achieve the effect. However, from the viewpoint of achieving a more remarkable effect, it is preferable to arrange a plurality of partitioning members. Also, when a plurality of partitioning members are arranged, it is preferable that at least two partitioning members are arranged so as to face each other. This can enhance the ventilation effect.

[0122] 3. Effects, etc. The partitioning member of the present disclosure and the partitioning device including the same exhibit the following effects.

[0123] Light can pass through the transparent portion of the partitioning member for lighting. When the partitioning device is provided with a plurality of partitioning members, in addition to the lighting of each partitioning member, by adjusting the positional relationship of the plurality of partitioning members, it is also possible to diversely create lighting effects in the space.

[0124] Air can pass through the transparent portion of the partitioning member for ventilation (air exchange). When the partitioning device is provided with a plurality of partitioning members, it becomes easier to control the flow of air flowing into the space and the flow of air flowing out of the space, and effective ventilation (air exchange) can be achieved.

[0125] Since air permeates through the permeable part of the partition member, droplets also permeate through it. However, as a result of the inventor's intensive research, it has been found that, in particular, droplets from people generated by conversation, coughing, sneezing, etc. can be effectively suppressed from permeating according to the configuration such as the partition member of the present disclosure. Therefore, according to the partition member of the present disclosure and the partitioning device including the same, it is possible to suppress the diffusion of droplets while having light transmissibility and air permeability. This is presumably because the particles of droplets generated from people are relatively large as droplets and have a fast moving speed, and such droplets are difficult to permeate through the permeable part of the partition member of the present disclosure.

[0126] Furthermore, if an anti-pathogen agent is disposed on the partition member, the growth of the virus attached to the partition member is suppressed, so that it is prevented from floating in the air again after leaving the partition member, and further the spread of the virus can be suppressed.

[0127] 4. Examples 4.1. Configuration of the test partition members used in Examples 1 to 8 In Examples 1 to 8, a partition member having a facing material disposed on the main body was created following the partition member 20 shown in FIGS. 8 to 11. Each configuration of the partition members used in Examples 1 to 8 is shown in Table 1. The honeycomb as the main body uses an aluminum honeycomb manufactured by Morishin Kogyo Co., Ltd. "Cell size (inch)" in Table 1 represents the distance between opposite sides of one cell that is a regular hexagon, following the normal notation method of the honeycomb core. In Examples 7 and 8, end members were also disposed, and an epoxy-based adhesive (Konishi Co., Ltd., MOS7, product number #4681 1) was used as the end member. The facing material used was a sheet of A1050 aluminum made by Mitsuwa Corporation, with a decorative material (Saffmire WS5088, manufactured by Dai Nippon Printing Co., Ltd.) with a woodgrain pattern with an adhesive attached thereto (in Example 1, the decorative material was not placed on one side). Here, the decorative material is a polypropylene sheet with an epoxy-based adhesive (Konishi Co., Ltd., MOS7, product number #46811) placed thereon. The openings of the facing material were formed by cutting to have the pitches shown in Table 1 in the X direction and Y direction between adjacent openings respectively.

[0128] In Examples 1 to 6, an adhesive was applied to the non-opening part of the facing material, and it was joined to and dried on the main body (honeycomb) to produce a partition member. On the other hand, in Examples 7 and 8, an end member was placed at the edge of the permeable part of the main body (honeycomb), and it was joined to and dried with the facing material to produce a partition member.

[0129] 4.2. Configuration of the test partition members used in Comparative Examples 1 to 5 The configurations of the partition members used in Comparative Examples 1 to 5 are shown in Table 2. More specifically, they are as follows. Comparative Example 1 was an example where no test partition member was used. In Comparative Example 2, a wire mesh material of a screen door was placed as the test partition member. The wire mesh was a Global Net made by Daito Kasei Co., Ltd., with a mesh size of 1.03 mm and 20 meshes, and an opening ratio of 66%. The thickness was 0.5 mm. In Comparative Example 3, square bars made of Japanese cypress with a cross-section of 18 mm × 18 mm and a length of 600 mm were arranged in parallel at intervals of 18 mm to form vertical louvers. In Comparative Example 4, a honeycomb board kraft (Hexa Japan Co., Ltd.) with a size of 910 mm × 910 mm and a thickness of 20 mm was used. In Comparative Example 5, a white lace curtain (Jitsukei Co., Ltd., Race Bits Color White) with a thickness of 0.2 mm was used.

[0130] 4.3. Test contents and test methods 4.3a. Difficulty of bending The bending resistance of the partition member was tested. Specifically, it is as follows. A diagram for explanation is shown in Fig. 16. Two base bars (aluminum angle bars) with a length of 500 mm and a square cross-section of 30 mm × 30 mm were prepared, installed in parallel with a spacing of 200 mm, and a test partition member with dimensions of 300 mm × 225 mm was placed on them. At this time, it is arranged so that the center of the side with a length of 300 mm is at the center of the spacing between the base bars. Then, a 1 kg weight (a weight for a tester industry co., ltd. friction fastness tester, academic promotion type) is placed at the center of the test partition member. As a result, when the partition member was bent by the weight and the partition member came into contact with the floor, it was marked as "×", and when it did not come into contact with the floor, it was marked as "〇". That is, the partition member marked as "〇" is more difficult to bend against an external force compared to the partition member marked as "×", and it can be said that it has high rigidity and strong stiffness.

[0131] 4.3b. Lighting property The lighting property of the partition member was tested. Specifically, it is as follows. Diagrams for explanation are shown in Figs. 17 and 18. As shown in Fig. 17, a cylinder (shielding cylinder) was formed with a material (packing cardboard) that shields light and air, and test partition members were arranged at the openings at both ends to fabricate a test partition device. The opening of this shielding cylinder is 225 mm wide and 300 mm long (in the height direction), and the length of the cylinder (distance between the openings) is 465 mm. Therefore, in this example, two test partition members are arranged facing each other with a spacing (465 mm) and with a shielding cylinder in between. One test partition member has a length of 300 mm and a width of 225 mm.

[0132] As shown in Fig. 18, one of the two test partition members was placed facing south (outdoors), and an illuminance meter was installed inside the shielding cylinder. The position of the illuminance meter was set such that the distance from the test partition member placed facing south to the detection part was 50 mm, and the height direction was approximately 0 mm (placed on the bottom of the shielding cylinder). Also, it was arranged at the center in the horizontal direction (225 mm direction) of the shielding cylinder. Measurements were taken from 12:00 to 14:00 in such a state, and the illuminance was measured at a certain time when there was solar radiation. In addition, in order to align the conditions, all the test partition devices according to Examples 1 to 8 and Comparative Examples 1 to 5 were fabricated and measured outdoors simultaneously. The illuminance meter used was the Ondotori TR-74Ui manufactured by Tianndo Di Co., Ltd.

[0133] 4.3c. Air permeability The air permeability of the partition member was tested. Specifically, it is as follows. A diagram for explanation is shown in Fig. 19. The test partition device is the same as that shown in Fig. 17. As shown in Fig. 19, air was sent from the outside to one of the two test partition members of the test partition member with a fan (Doushisha Co., Ltd., FIM-102). The fan was installed at a position 100 mm horizontally from the test partition member and 50 mm from the lower end of the shielding cylinder, and the direction of the wind was adjusted so that the direction of the rotation axis of the fan blades was 45° upward with respect to the horizontal as shown in Fig. 19. On the other hand, an anemometer (Testo Co., Ltd., TESTO445) was installed inside the shielding cylinder. The position of the anemometer was set such that the distance from the test partition member on the side where the fan was installed to the detection part was 200 mm, and the height direction was also 200 mm. Also, it was arranged at the center in the lateral direction (225 mm direction) of the shielding cylinder. The wind speed was measured in such a state.

[0134] 4.3d. Droplet diffusion The droplet diffusibility of the partition member was tested. Specifically, it is as follows. Diagrams for explanation are shown in Figs. 20 and 21. The test partition device is the same as that shown in Fig. 17. As shown in FIGS. 20 and 21, a liquid was sprayed onto one of the two test partition members with a spray (Trust Co., Ltd., Bed Straightening Styling Water). FIG. 20 is a view seen from the front, and FIG. 21 is a view seen from above. The spray was installed so that it was 500 mm in the horizontal direction from the test partition member, 300 mm from the lower end of the shielding cylinder, and the injection direction was at an angle of 45° with respect to the normal line of the test partition member when viewed from above as shown in FIG. 21, and the liquid was sprayed toward the center of the test partition member. On the other hand, a particle sensor (Omron Corporation, ZN-PD50-S) was installed inside the shielding cylinder. The position of the particle sensor was such that the distance from the test partition member on the side where the spray was installed to the detection part was 100 mm, and the height direction was 150 mm. Also, it was arranged at the center in the lateral direction (225 mm direction) of the shielding cylinder. In such a state, 20-μm particles (corresponding to droplets from a person) were collected every second for 7 seconds, and the number was counted.

[0135] 4.3e. Sound The sound permeability of the partition member was tested. Specifically, it was as follows. A diagram for explanation is shown in FIG. 22. The test partition device was the same as that shown in FIG. 17. As shown in FIG. 22, sound was emitted from a sound source (incoming call sound of a smartphone, maximum volume) from the outside of one of the two test partition members. The sound source was installed at a position 100 mm in the horizontal direction from the test partition member and 150 mm from the lower end of the shielding cylinder. On the other hand, a noise meter (Rion Co., Ltd., ordinary noise meter NL-42) was installed inside the shielding cylinder. The position of the noise meter was such that the distance from the test partition member on the side where the sound source was installed to the detection part was 200 mm, and the height direction was approximately 0 mm (placed on the bottom of the shielding cylinder). Also, it was arranged at the center in the lateral direction (225 mm direction) of the shielding cylinder. In such a state, the noise was measured.

[0136] 4.3f. Visual Recognition Test Using one of the test partition members used in Example 3, Example 4, Example 5, Example 8, and Comparative Examples 1 to 5, a visibility test was conducted through the partition member on the opposite side. Fig. 23 shows a diagram explaining the test method. Fig. 23 is a view looking down from above.

[0137] As shown in Fig. 23, the test partition members for each example were manufactured and installed with a horizontal dimension of 910 mm and a vertical dimension of 1950 mm (the size in the depth direction of the paper surface). People were placed in a standing position at positions 1000 mm on each side (Person A) and the other side (Person B) with the test partition member in between (front view). The circles in Fig. 23 indicate the positions of the heads of the people. A similar test was also conducted when Person A moved to a position 30 degrees with respect to the partition member (diagonal 30 degrees). In such a state, it was examined whether Person A could recognize the expression of Person B. Regarding "recognition of expression", the case where Person A could visually recognize the expression of Person B with eyes open was marked as "〇", and the case where it could not be visually recognized was marked as "×".

[0138] 4.3g. Deformation Test In the deformation test, the test was conducted by changing the size and arrangement of the test partition members used in Example 3, Example 4, Example 5, Example 8, and Comparative Examples 1 to 5. The details are as follows. Fig. 24 shows a diagram for explanation. Fig. 24 is a view from above. Two test partition members with a horizontal dimension of 910 mm and a height (depth / front direction of the paper surface) of 1950 mm were prepared. One of the two test partition members was placed facing south (outdoor), and the other was placed facing west (outdoor). An illuminance meter and a thermometer were installed on the north side back surface of the south-facing partition member. The position of the illuminance meter and thermometer was such that the distance from the south-facing test partition member to the detection part installed on the north side was 50 mm, and the height direction (depth / front direction of the paper surface) was approximately 500 mm. Measurements were taken from 11:00 to 15:00 in such a state, and the temperature and illuminance were measured at certain times when there was sunlight. In order to standardize the conditions, all the test partition members for all the examples (Examples 11 to 14) and comparative examples (Comparative Examples 11 to 15) were manufactured and measured outdoors simultaneously. The illuminance meter used was the Ondotori TR-74Ui manufactured by Tian Duo Di Co., Ltd.

[0139] 4.4. Results The results of the tests are shown in Table 1 (Examples 1 to 8) and Table 2 (Comparative Examples 1 to 5).

[0140]

Table 1

[0141]

Table 2

[0142] It can be seen that the test partition devices according to Examples 1 to 8 have an appropriately high illuminance and can achieve daylighting. In contrast, for those that allow light to pass through in the comparative examples (Comparative Examples 1 to 3, Comparative Example 5), the illuminance during solar radiation is high, and it feels dazzling, so it cannot necessarily be said that it is appropriate daylighting. On the other hand, for those that do not allow light to pass through (Comparative Example 4), the illuminance is extremely low. Also, regarding the wind speed, in the examples, an appropriate magnitude is obtained compared to the comparative examples, and ventilation is ensured. From the above, it can be seen that in the examples, daylighting and ventilation inside can be realized in a well-balanced manner, and the comfort of the indoor space can be improved.

[0143] Regarding droplets, in the examples, it was possible to reduce them compared to Comparative Examples 1 to 3 and Comparative Example 5, all of which have air permeability.

[0144] Also, it can be seen that Examples 1 to 8 have higher bending strength compared to Comparative Examples 2 and 5.

[0145] From the above, according to the examples, while obtaining the comfort of the internal space environment, a remarkable effect is achieved in suppressing the spread of droplets. Also, regarding sound (noise), there is no significant difference between the examples and the comparative examples, and it can be seen that the sound is appropriately transmitted inside for the examples.

[0146] Also, according to the embodiment, the expressions of people on the opposite side across the partition member can be visually recognized from the front, but cannot be visually recognized at an angle of 30 degrees. On the other hand, such adjustment cannot be made in the comparative example. According to this result, with the partition member of the present disclosure and the partition device using the same, it is possible to finely control the sense of distance from people according to the angle with the partition material, such as concentrating on one's own work while feeling the presence of people on the opposite side of the partition member and the partition device. During remote work and work at home, it is possible to create a place like a semi-room with a sense of openness in a small area while maintaining concentration, or to selectively shield the scenery on the opposite side at the position of the partition member to adjust what can be seen (shown), and to create different light environments while being in the same space.
