[0009] According to the present invention, it is possible to provide an interior material that improves the spatial environment of a house or the like. [Brief explanation of the drawings]

[0010] [Figure 1] 3 is a flowchart of a method for applying an interior material according to the present embodiment. [Figure 2] FIG. 2 is a cross-sectional view of the interior structure of the present embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments of the interior material, interior material, application method, and interior structure will be specifically described, but the present invention is not limited to these embodiments.

[0012] <Interior materials> The interior material, which is the raw material for the interior material of this embodiment, contains diatomaceous earth as a main component, with green schist and the like dispersed in the diatomaceous earth. Diatomaceous earth is primarily composed of silicon dioxide and has a porous structure. Its fine pores provide humidity control and deodorizing effects. Furthermore, the diatomaceous earth of this embodiment is designed to house, for example, microorganisms (e.g., bacteria) that have a beneficial effect on the living environment. The interior material of this embodiment is primarily applied to the interior walls and ceilings located inside rooms of houses such as dwellings.

[0013] The diatomaceous earth is formed into a powder with an average particle size of 100 μm to 1 mm. Wakkanai diatomaceous earth produced in the Wakkanai region of Hokkaido is preferably used. However, the diatomaceous earth is not limited to Wakkanai diatomaceous earth, and may be produced outside the Wakkanai region.

[0014] Also, so-called mesopore diatomaceous earth, in which the inner diameter (diameter) of the pores is approximately 2 nm to 50 nm, is preferred. In particular, mesopore diatomaceous earth produced in Hokkaido has pores with diameters of 2 nm to 50 nm, which allows for greater humidity control and deodorizing effects. Furthermore, the diatomaceous earth of this embodiment is not fired. By using unfired diatomaceous earth in the interior material of this embodiment, microorganisms that adhere to the diatomaceous earth and have a beneficial effect on the spatial environment are utilized.

[0015] The green schist used in the interior material of this embodiment is a green schist-like metamorphic rock containing chlorite, epidote, and oxalite, and has a porous structure. More specifically, because of its continuous porous structure, it has a large specific surface area and excellent adsorption capacity as a filter.

[0016] Greenschist has a high adsorption capacity and can absorb and trap chlorine, metal compounds, trihalomethanes, etc. in water. Note that "chlorine" here refers to the chlorine contained in tap water, including sodium hypochlorite and potassium hypochlorite.

[0017] In the interior material of this embodiment, at least diatomaceous earth, green schist, and tap water are mixed in the mixing process described below. During this process, impurities contained in the tap water, such as chlorine, are adsorbed onto the green schist. This prevents impurities, such as chlorine, from adhering to the diatomaceous earth. This prevents the micropores in the diatomaceous earth from being blocked by impurities and makes it easier for microorganisms that have a beneficial effect on the spatial environment to live without being affected by impurities. This allows the interior material of this embodiment to utilize the humidity-regulating and deodorizing effects inherent to diatomaceous earth, enhancing its functionality as an interior material.

[0018] The green schist of this embodiment can be preferably obtained by crushing raw green schist ore. The green schist used is powder with an average particle size of 5 μm to 10 μm. The green schist used as the raw material can be green schist of the Sanbagawa metamorphic rock obtained from a crystalline schist belt known as the Sanbagawa belt. The main component of green schist is a submarine layer dating back 250 million to 65 million years. In particular, green schist mined in the Koshinetsu region is preferred, and as a commercially available product, Chuseki (registered trademark) crushed into powder of the above particle size can be preferably used.

[0019] Furthermore, in the interior material of this embodiment, the average particle size of the green schist is smaller than that of the diatomaceous earth. As a result, in this embodiment, when applying the interior material to a wall surface or the like, the particle size of the green schist is smaller than that of the diatomaceous earth, which is the main component, so that the green schist does not affect application properties such as ease of spreading. In particular, in the interior material of this embodiment, by dispersing the green schist with a small particle size in the diatomaceous earth, the green schist acts as a lubricant, making the paste-like interior material easier to spread during application.

[0020] The interior material of this embodiment may contain white clay as a binder. Specifically, volcanic ash clay can be used. To give the interior material a white finish, it is preferable to use white volcanic ash clay.

[0021] The interior material of this embodiment may further contain starch paste as a binder. The inclusion of starch paste improves application. Note that using a chemical paste may form a film on the surface of the diatomaceous earth, which may impair the moisture-regulating effect, so it is preferable to use an edible starch paste.

[0022] The interior material of this embodiment may further contain cellulose fiber as a binder. Specifically, wood fiber such as recycled paper can be suitably used. Cellulose fiber improves crack prevention after application.

[0023] In addition, zeolite may be included. Zeolite (zeolite) is a general term for silicates with micropores in the crystals, and has adsorption and deodorizing effects. Furthermore, the interior material of this embodiment may also include color powder. As the color powder, inorganic mineral pigments are preferred.

[0024] <Raw material composition> The interior material of this embodiment may be mixed with interior materials such as diatomaceous earth or green schist before construction. The recommended mixing ratio is 70 to 99% by weight of diatomaceous earth, assuming the total weight of the interior materials is 100%. If the diatomaceous earth mixing ratio is below this range, the adhesive strength to the application surface will be insufficient, which may result in poor application performance and cause cracking and peeling after application.

[0025] Furthermore, when the total amount of the interior materials is 100% by weight, it is preferable that the green schist be contained in an amount of 1 to 15% by weight. Although the blending ratio of the green schist is not limited to the above range, as long as the blending ratio is contained, it is possible to obtain the effect of removing chlorine and other substances from tap water.

[0026] Furthermore, when the total amount of the interior material is taken as 100% by weight, the material may contain 10 to 30% by weight of white clay. If the blending ratio of white clay exceeds this range, the humidity-regulating effect of the diatomaceous earth may decrease.

[0027] Furthermore, when the total amount of the interior material is taken as 100% by weight, the interior material may contain 0.1 to 1% by weight of starch paste. In addition, the interior material may contain 0.1 to 1% by weight of cellulose fiber. The interior material may contain both starch paste and cellulose fiber, or may contain only one of them.

[0028] The interior material of this embodiment has a blend ratio of 75% by weight of diatomaceous earth, 5% by weight of green schist, 19% by weight of white clay, and 1% by weight of starch paste and cellulose, assuming the total amount of the interior material is 100% by weight. This is the most preferable blend ratio in this embodiment. However, it goes without saying that the blend ratio is not limited to this. <Construction method>

[0029] The paste-like interior material of this embodiment is applied to the wall surfaces of a building by troweling, and also to the ceiling surface by spraying. When carrying out construction work, the interior material of this embodiment is first prepared. It is preferable to mix the raw materials of the interior material in advance before entering the construction site. However, if there is a means for mixing the raw materials at the construction site, they may be mixed on-site. When mixing the raw materials on-site in this way, it is not necessary to mix all the raw materials on-site; only some of the raw materials, such as green schist, may be mixed on-site.

[0030] FIG. 1 is a flowchart of the method for applying an interior material according to this embodiment.

[0031] An example of construction using the interior material of this embodiment is as follows: The surface to be constructed is treated in the same manner as in the construction of a general plastered wall. First, as shown in Fig. 1, a preparation step is performed in which a predetermined amount of tap water is collected in a container (S101). The amount of water to be added here is preferably 11 L to 12 L for 10 kg of interior material. In this embodiment, tap water is used as the water to be mixed with the interior material. Tap water is easy to prepare at the site where the interior material of this embodiment is to be installed. Therefore, using tap water as the water increases the efficiency of the installation work.

[0032] Then, the interior material containing diatomaceous earth, green schist, etc. is dropped into a container filled with a predetermined amount of tap water. In other words, the interior material is added to the tap water that has been prepared in advance. Then, a mixing process is performed in which the interior material and tap water are mixed together (S102). This makes the interior material less likely to form lumps, improving the ease of application when applying the paste-like interior material to a wall surface. Furthermore, compared to pouring water into accumulated interior materials from above, for example, by sprinkling the interior materials into tap water, the green schist in the interior materials comes into contact with the water more easily, which accelerates the removal of impurities in the tap water, such as calcium carbonate, by the green schist.

[0033] Thereafter, the interior material is added to the tap water, and then a stirring step is carried out in which the interior material and the tap water are stirred using a stirring device such as a mixer (S103). This allows the tap water and the interior material to be kneaded together, producing a paste-like interior material.

[0034] After the stirring process is completed, a settling step is performed in which the stirred paste-like interior material is settling (S104). The settling time for the interior material is preferably 30 minutes or more and 90 minutes or less. By setting the mixed interior material to stand for such a certain period of time, moisture penetrates sufficiently into the interior of the diatomaceous earth particles, for example, making the interior material smooth. This also improves the ease of application when applying the interior material to a wall surface, etc. Note that if the setting time is less than 30 minutes, moisture will not penetrate sufficiently into the interior of the diatomaceous earth particles. On the other hand, if the setting time is more than 90 minutes, the moisture in the interior material will evaporate and hardening will begin. Note that the interior material of this embodiment is settling for approximately 60 minutes after the stirring process.

[0035] Generally, tap water is used in construction, but tap water contains so-called chlorine, such as sodium hypochlorite and potassium hypochlorite. The chlorine contained in tap water adheres to the diatomaceous earth, eliminating the effectiveness of the minerals contained in the diatomaceous earth. In addition, the action of the chlorine tends to harden the paste-like interior material, making it difficult to apply.

[0036] In this regard, the green schist contained in the interior finishing material of this embodiment adsorbs and removes the chlorine contained in tap water, preventing the chlorine from adhering to the diatomaceous earth. This removal of chlorine by the green schist begins when tap water is added to the interior finishing material, but also progresses during the process of stirring the interior finishing material with tap water and the process of leaving the paste-like interior finishing material after stirring.

[0037] In the process of removing chlorine using green schist, it is preferable to reduce the residual chlorine in the tap water to zero, but it is not necessary to completely remove it to zero. By reducing the relative amount of residual chlorine in the tap water, the amount of chlorine adhering to the diatomaceous earth also decreases.

[0038] After the interior material has been mixed and left to stand (set still) for a predetermined time, an application step is carried out in which the paste-like interior material is applied to the wall surface (S105). The application to the surface to be applied is carried out using, for example, a plastering trowel, but a roller or brush may also be used if necessary. The interior material is preferably applied to the surface to be applied to a thickness of 1.5 mm to 3 mm. After the interior material has been applied to the surface to be applied, the interior material is allowed to dry naturally, completing the series of steps.

[0039] After the interior material has been stirred and left to stand for a predetermined time, a re-stirring step may be carried out to stir the paste-like interior material again. This allows the materials constituting the interior material and the water to be mixed uniformly, creating a state suitable for application.

[0040] The interior material of this embodiment can be suitably used on the wall and ceiling surfaces of ordinary homes and various buildings. The interior material of this embodiment has an excellent humidity-regulating effect, making it difficult for condensation to form indoors and suppressing the growth of mold and mites that feed on mold. The interior material of this embodiment also adsorbs odors and harmful volatile chemicals, purifying the air in the room. Furthermore, the interior material of this embodiment provides an environment that is conducive to the habitation of microorganisms that have beneficial effects on humans. In this way, the interior material of this embodiment can improve the spatial environment.

[0041] In addition, when only the green schist among the raw materials of the interior material is mixed with other raw materials on site, first, it may be added to water in the state of only the green schist. That is, in the mixing process, the green schist is added to tap water prior to the diatomaceous earth. And after adding the green schist to the tap water, it may be left in that state for a predetermined time (for example, 60 minutes). Thereby, the removal of impurities such as chalk in the tap water progresses. The remaining diatomaceous earth as the interior material may then be appropriately mixed with the tap water to which the green schist has been added.

[0042] Figure 2 is a cross-sectional view of the interior structure 1 of the present embodiment.

[0043] As shown in FIG. 2, the interior structure 1 of the present embodiment includes a floor material 2 constituting the floor surface, a base material 3 constituting the wall surface, the interior material 10 of the present embodiment, and a skirting 5. Before applying the interior material 10, general base treatment is performed on the base material 3. The base material 3 is not particularly limited as long as it can be a base for a general painted wall, such as a plaster board, mortar, concrete, cross wall, veneer board, etc.

[0044] Then, a paste-like interior material 10 containing diatomaceous earth and green schist is applied to the base material 3. The thickness L1 of the interior material 10 of the present embodiment has a thickness of about 1.5 mm to 3 mm. The thickness L1 of this interior material 10 is smaller than the thickness L2 of the floor material 2 of the present embodiment (L1 < L2). In the interior structure 1 of the present embodiment, by making the thickness L1 of the interior material 10 smaller than the thickness L2 of the floor material 2, the amount of moisture adsorbed by the diatomaceous earth in the interior material 10 and the amount of components released from the floor material 2 described later are made appropriate. That is, when the thickness L1 of the interior material 10 is, for example, larger than the thickness L2 of the floor material 2, the amount of the above-mentioned moisture and active components absorbed by the interior material 10 may become too large, and conversely, the effects due to humidity and released components may be reduced. Therefore, in the present embodiment, by making the thickness L1 of the interior material 10 smaller than the thickness L2 of the floor material 2, a balance is achieved between the amount of components released from the floor material 2 and the amount of moisture and components adsorbed by the interior material 10.

[0045] Furthermore, a baseboard 5 is provided below the interior material 10. The baseboard 5 is provided so as to come into contact with the base material 3 and the floor material 2, respectively.

[0046] In this embodiment, flooring 2 is used. While there are no particular restrictions on the type of flooring material, it is preferable to use cedar as the raw material, and more preferably, Yakushima cedar as the raw material. Here, "Yakushima cedar" refers to cedar derived from Yakusugi trees, which are grown from seeds or grafts harvested from Yakusugi trees that grow naturally at an altitude of 1,000 meters. This differs from the "Yakusugi" trees that are over 1,000 years old and grow naturally at altitudes of 500 meters or more on Yakushima, and cutting of which is currently prohibited.

[0047] Yakushima cedar is said to contain approximately 20 times the amount of cedrol, a fragrance component, compared to Japanese cedars grown in regions other than Yakushima. This strong fragrance has a relaxing effect on the mind and body. Furthermore, Yakushima cedar has a higher content of cryptomerion and β-eudesmol than mainland cedars, making it highly effective at preventing dust mites. In particular, the Yakushima cedar used as the flooring material 2 of this embodiment is known as solid wood, meaning that it is not made by gluing together multiple pieces of wood with an adhesive, but is made from the wood itself. Furthermore, the Yakushima cedar used as the flooring material 2 of this embodiment does not have a surface coating, for example, and the wood itself forms the surface.

[0048] The combination of the interior material 10 applied to the wall surface and the flooring material 2 made of Yakushima cedar, as in this embodiment, provides the following benefits. As described above, beneficial components are released from the Yakushima cedar. In a space where the wall surface equipped with the interior material of this embodiment is not used, the released components tend to escape from the space. In contrast, in a space where the interior structure of this embodiment is used, the green schist allows the presence of diatomaceous earth whose micropores are not blocked by impurities. Therefore, the components released from the Yakushima cedar are more likely to be retained in the pores of the diatomaceous earth. Furthermore, the humidity-regulating effect of the diatomaceous earth maintains a humidity level suitable for the release of beneficial components from the Yakushima cedar. Thus, the interior structure of this embodiment creates a desirable interior space through the synergistic effect of the Yakushima cedar flooring and the diatomaceous earth on the wall surface.

[0049] In the interior structure 1 of the above-described embodiment, Yakushima cedar is used for the flooring 2, but this is not a limitation. For example, wood materials obtained in other regions, such as cedar, oak, oak, and walnut, may also be used for the flooring 2. The flooring 2 may also be made of an aggregate material made by bonding together multiple pieces of wood with an adhesive. In this case, in the interior structure 1 of this embodiment, even if chemical substances such as adhesives are generated from the flooring 2, the chemical substances can be absorbed by the interior material 10 of this embodiment, creating a favorable spatial environment.

[0050] Furthermore, in the interior structure 1 of the above-described embodiment, the thickness of the interior material 10 is approximately uniform in the height direction (vertical direction) in the space, for example, but is not limited to this. The thickness of the interior material 10 may vary in the height direction. For example, the thickness of the interior material 10 at a first height from the floor material 2 may be greater than the thickness of the interior material 10 at a second height lower than the first height. In other words, the thickness of the interior material 10 may be formed to be greater at higher positions than at lower positions. In this case, the interior material 10 that forms the wall surface of the space will protrude from the wall surface side toward the center of the space. This makes it possible for the interior material 10 to absorb chemical substances and moisture released from, for example, the floor material 2, by enveloping them from above.

[0051] Furthermore, in the interior structure 1 described above, the composition ratio of the constituent materials such as diatomaceous earth, green schist, and white clay in the interior material 10 is approximately uniform, for example, in the height direction (vertical direction) in the space, but is not limited to this form. The composition ratio (concentration) of the constituent materials of the interior material 10 may vary in the height direction. For example, the ratio of white clay in the interior material 10 at a first height from the floor material 2 may be higher than the ratio of white clay in the interior material 10 at a second height lower than the first height. In other words, the ratio (concentration) of diatomaceous earth and green schist in the interior material 10 is configured to be relatively higher at lower positions than at higher positions. This allows the humidity control and adsorption properties of the diatomaceous earth and green schist in the interior material 10 to be maintained high at the height of a person who is active at a relatively low position in the space, while the concentrations of diatomaceous earth and green schist at positions higher than the person in the space can be reduced, thereby reducing material costs.

[0052] The present disclosure is not limited to the above-described embodiments, and can be implemented in various forms without departing from the spirit of the present disclosure. [Explanation of symbols]
