[0002] When functional layers such as dimming films are applied to vehicle laminated glass, they are easily corroded by water vapor in the environment or small molecule plasticizers in the interlayer film, which affects the function. Therefore, functional layers such as dimming films need to be edge-sealed to prevent corrosion from various substances in the environment.

[0003] However, when the edge sealing method used in traditional technology is applied to the edge sealing of the functional layer, the edge sealing effect is poor. Summary of the invention

[0004] Based on this, it is necessary to provide a laminated component and a preparation method and a vehicle that take into account both narrow edge sealing and edge sealing flatness.

[0005] In a first aspect, a laminated assembly is provided, comprising:

[0006] a first transparent substrate;

[0007] a second transparent substrate;

[0008] The functional layer is arranged between the first transparent substrate and the second transparent substrate. At least part of the edge area of ​​the functional layer has a groove, the groove at least runs through one side of the functional layer, and the notch of the groove is covered with an edge strip so that the edge strip and the groove form a sealed cavity.

[0009] In one of the embodiments, the edge banding strip is a flexible edge banding strip, and the edge banding strip is recessed in the groove based on the sheet-joining and air-evacuation process.

[0010] In one of the embodiments, when the groove passes through two side surfaces of the functional layer and the width of the groove is greater than the first preset width, the edge banding strips on both sides of the groove are adsorbed to each other;

[0011] When the groove passes through one side surface of the functional layer and the width of the groove is greater than the first preset width, the edge banding strip covered by the notch of the groove is adsorbed on the bottom surface of the groove.

[0012] In one embodiment, the vacuum degree of the sealed cavity is less than a preset vacuum degree, or the sealed cavity is filled with an inert gas.

[0013] In one embodiment, the laminated component is vehicle glass.

[0014] In one embodiment, at least a portion of the laminated assembly is embedded in the vehicle body, and the laminated assembly is movable, and at least an edge region of the functional layer outside the water line of the vehicle body has a groove.

[0015] In one embodiment, the laminated assembly further comprises:

[0016] The adhesive layer is located between the first transparent substrate and the second transparent substrate, and the adhesive layer covers the functional layer and the edge sealing strip.

[0017] In one embodiment, the shape of the edge band matches the outer contour of the corresponding edge region.

[0018] In a second aspect, a method for preparing a laminated component is provided, the method comprising:

[0019] Provides functional layer;

[0020] In at least a portion of the edge region of the functional layer, cutting to form a groove that penetrates at least one side of the functional layer;

[0021] Cover the edge banding in the notch of the groove;

[0022] A first transparent substrate and a second transparent substrate are provided, and based on a lamination and exhaust process, the functional layer covered with the edge band is laminated with the first transparent substrate and the second transparent substrate on both sides to form a laminated component.

[0023] In one embodiment, when the groove penetrates one side of the functional layer, before the step of covering the edge banding strip at the notch of the groove, the method further includes:

[0024] The liquid crystal in the groove is cleaned until the groove has a smooth liquid crystal-free strip with at least a second preset width.

[0029] There is a functional layer between the first transparent substrate and the second transparent substrate, and the edges of the functional layer are all sealed to prevent corrosion from various substances in the environment, wherein, in at least part of the edge area of ​​the functional layer, a groove is opened that passes through at least one side of the functional layer, and the edge is sealed by covering the groove with an edge band, so that the groove and the edge band form a sealed cavity to protect the functional layer. In the laminated structure of the edge band, the transparent substrate and the functional layer, the groove width can be designed as a narrow groove, and it is suitable for laminated components of any shape, which is conducive to realizing a narrow edge design while ensuring the flat attachment of the edge and improving the edge quality.

[0043] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0045] It should be understood that when a layer is referred to as being "on", it may be directly on other layers, or there may be intervening layers. Conversely, when a layer is referred to as being "directly on", there are no intervening layers. It should be understood that although the terms first, second, etc. may be used to describe various layers, these layers should not be limited by these terms. These terms are merely used to distinguish one layer from another. Thus, for example, a first transparent substrate may be referred to as a second transparent substrate, and similarly, a second transparent substrate may be referred to as a first transparent substrate; the first transparent substrate and the second transparent substrate are different transparent substrates.

[0046] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0047] Functional glass such as dimming glass has been increasingly used in various scenarios such as automobiles, smart conference rooms, and hotels. For example, in the automotive field, a dimming layer can be set in the laminated glass of the vehicle, and the glass light and line of sight can be adjusted by energizing the dimming layer to meet the needs of users in different scenarios. When the dimming layer is used in laminated glass, it is easily corroded by water vapor in the environment or small molecule plasticizers in the interlayer film. Therefore, the dimming layer needs to be edge-sealed to prevent corrosion from various substances in the environment.

[0048] The edge sealing technologies in traditional technology include Y-shaped edge sealing, U-shaped edge sealing, edge sealing with edge sealing glue, etc. Most of them are suitable for dimming sunroof glass products. Since the four sides of the sunroof glass can be covered by the ink printed edges of the glass, and it is basically a fixed and non-openable sunroof, the edge sealing of various dimming layers in the vehicle is basically invisible. Unlike the sunroof glass, the side window glass can be raised and lowered. During the raising and lowering process, its top edge and at least part of the side edge are visible and exposed outside the vehicle body, which will affect the light transmittance of the side window glass and affect the appearance. Therefore, there are more stringent specifications and size requirements for the edge sealing appearance of this exposed area.

[0049] If the traditional Y-shaped edge sealing method is used, the edge sealing strip needs to be extended and overlapped at the outer edge of the dimming layer, which reduces the width of the middle layer of film that can be filled, making it difficult to assemble the sheets. The U-shaped edge sealing method is difficult to attach evenly at the R corner of the window glass.

[0050] Based on this, in one embodiment, Figure 1 As shown, a stacked component 100 is provided, including: a first transparent substrate 10 , a second transparent substrate 20 and a functional layer 30 .

[0051] Among them, the functional layer 30 is arranged between the first transparent substrate 10 and the second transparent substrate 20, and at least part of the edge area of ​​the functional layer 30 has a groove 31, the groove 31 at least passes through one side of the functional layer 30, and the notch of the groove 31 is covered with an edge banding strip 40, so that the edge banding strip 40 and the groove 31 form a sealed cavity.

[0052] The first transparent substrate and the second transparent substrate refer to substrates that are light-transmissive and can provide a certain support. For example, the first transparent substrate and the second transparent substrate can be, but are not limited to, a glass plate, a transparent polyimide (PI) plate, a transparent plastic plate, and the like.

[0053] A functional layer refers to a film layer that can achieve at least one function. For example, the functional layer may include, but is not limited to, a photoresponsive functional layer, a temperature regulating layer, a silver-plated layer, and a low-emissivity (LOW-E) layer. Taking the photoresponsive functional layer as an example, by changing the connected electrical signal, changes in light transmittance, light absorptivity, and light reflectivity can be achieved. For another example, for the temperature regulating layer, the temperature of the laminated component can be changed by changing the connected electrical signal. It should be understood that the functional layer in this case includes the type of functional layer that requires edge protection in the laminated component, and the types of functional layers are not exhaustively listed here.

[0054] There are two cases where the groove penetrates at least one side of the functional layer:

[0055] When the groove passes through the two sides of the functional layer, a through groove is formed, and there are notches on both sides of the functional layer. Figure 1-Figure 4 As shown, the two grooves on both sides of the functional layer 30 are covered with edge banding strips 40 .

[0056] When the groove passes through one side of the functional layer, a blind groove is formed and has a notch. Figure 5-Figure 7 As shown, this groove on one side of the functional layer 30 is covered with an edge strip 40 .

[0057] The selection of at least part of the edge area of ​​the functional layer can be determined in combination with the user's visible area in the application scenario of the laminated component. The "at least part of the edge area of ​​the functional layer" mentioned in the edge sealing method based on the edge banding strip in the above embodiment should at least include the user's visible area. For example, when the laminated component is a side window glass, "at least part of the edge area of ​​the functional layer" should at least include the area on the functional layer that is above the water tangent line of the vehicle body.

[0058] For an understanding of edge banding covering notches, see Figure 1-Figure 7 As shown, the edge banding strip 40 covers the groove 31 by being placed on the surface of the functional layer 30 on both sides of the groove 31 and using the surface of the functional layer 30 as a support point.

[0059] like Figure 1As shown, the laminated component 100 provided in the embodiment of the present application has a functional layer 30 between the first transparent substrate 10 and the second transparent substrate 20, and the edges of the functional layer 30 are all sealed to block the erosion of various substances in the environment, wherein at least part of the edge area of ​​the functional layer 30 is sealed by adopting the edge sealing method in the above embodiment, specifically, a groove 31 that runs through at least one side of the functional layer is opened in at least part of the edge area of ​​the functional layer 30, and the edge sealing strip 40 is covered on the groove to seal the functional layer 30, and the sealed cavity formed by the groove 31 and the edge sealing strip 40 can protect the function of the functional layer 30 from being eroded by various substances in the environment. In the laminated component 100 provided in the embodiment of the present application, the edge sealing strip 40, the transparent substrates (10 and 20) and the functional layer 30 are stacked in a laminated structure, and the width of the groove 31 can be designed as a narrow groove, and it is suitable for laminated components 100 of any shape, which is conducive to realizing a narrow edge sealing design while ensuring the flat attachment of the edge sealing and improving the edge sealing quality.

[0060] In addition, in the structure where the edge banding strip 40 covers the notch of the groove 31, the processing of the edge banding strip 40 and the processing of the functional layer with the groove 31 can be carried out simultaneously, and then the processed edge banding strip 40 can be covered on the notch 31. Compared with traditional edge banding material filling methods, the processing speed of the laminated component can be greatly improved.

[0061] The area of ​​the functional layer is preferably smaller than that of the first transparent substrate and the second transparent substrate, and the edge banding strip does not need to exceed the edge of the functional layer, which will not cause the edge filling width of the outer periphery of the functional layer to be reduced, making it easy to assemble the sheets, which is conducive to speeding up the edge banding process.

[0062] It should be noted that the functional layers in the laminated components provided in the embodiments of the present application are all protected by edge sealing to isolate them from various substances in the environment from erosion. The above embodiments are intended to introduce that the functional layers in some or all areas of the laminated components can adopt this edge sealing method to achieve a narrow edge sealing design in some or all areas, that is, the edges of the functional layers in the areas not visible to users can also adopt the edge sealing method of grooves on the edges of the functional layers and the grooves covering the edge sealing strips. As for the edges of the functional layers that do not adopt the edge sealing method in the above embodiments and are not edge sealed, other edge sealing methods can be used for edge sealing, for example, the Y-shaped edge sealing method and U-shaped edge sealing method introduced above.

[0063] In one embodiment, the edge banding strip is covered on the functional layer in a manner including but not limited to electrostatic adsorption, adhesive adhesion, tape bonding, and the like.

[0064] In one embodiment, the edge banding strip is a transparent edge banding strip. The edge banding strip is made of transparent material, and the optional edge banding strip can be made of at least one transparent material selected from epoxy adhesive, acrylate adhesive, polyurethane adhesive, and silicone adhesive. The edge banding strip formed by using at least one of the above transparent materials is in the form of a transparent adhesive film. Compared with the milky white curing adhesive method in the traditional technology, the problem of slow production cycle caused by long curing adhesive processing time and the need for baking can be avoided, thereby reducing production costs.

[0065] In some embodiments, the material of the edge strip may also be other transparent plastics other than those exemplified above. For example, the edge strip may be a rigid material such as polyester that can withstand a certain strain.

[0066] The laminated component provided in the embodiment of the present application has a groove opened in the edge area of ​​the functional layer, at least in the user-visible area of ​​the laminated component, and the notch area of ​​the groove is covered with a transparent and barrier edge strip, without the need for an external edge strip, so as to achieve a transparent, beautiful, efficient, low-cost and high-quality edge sealing effect.

[0067] In one embodiment, the edge banding strip may have high temperature resistance and / or low temperature resistance to ensure the reliability of edge banding of the laminated component under different temperature environments. For example, when the laminated component is a vehicle-mounted glass, the material of the edge banding strip may withstand a high temperature of 150°C for 1 hour without cracking or wrinkling, so as to ensure that the barrier effect of the edge banding strip is not affected when the vehicle is exposed to the sun for a long time, thereby ensuring the reliability of the functional layer.

[0068] In one embodiment, the edge banding is a flexible edge banding such as Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, the edge banding strip 40 is sunken in the groove 31 based on the vacuum process of the sheet assembly. When the sheet assembly is vacuumed (vacuumed), a negative pressure environment is formed in the area where the groove 31 is located, causing the edge banding strip 40 in the area of ​​the groove 31 to bend and sunken in the groove 31, forming a vacuum barrier layer and / or a physical barrier layer to protect the functional layer 30 from being eroded by various substances.

[0069] In one embodiment, for the flexible edge banding, Figure 3 As shown, when the groove 31 passes through two side surfaces of the functional layer 30 and the width of the groove 31 is greater than the first preset width, the edge banding strips 40 on both sides of the groove 31 are adsorbed on each other.

[0070] The first preset width can be determined based on the depth of the groove and the elastic modulus of the flexible edge banding. The deeper the groove, the larger the first preset width, and the two are positively correlated; the smaller the elastic modulus of the flexible edge banding (the smaller the elastic modulus, the greater the deformation of the flexible edge banding under the same stress), the smaller the first preset width, and the two are positively correlated.

[0071] When the width of the groove is greater than the first preset width, when the sheets are assembled based on the assembly vacuum process, the edge strips on both sides are adsorbed to each other due to the negative pressure in the through groove, and then attached together to form a physical barrier layer (see Figure 3 ), so as to perform edge sealing protection on the functional layer. Optionally, in one embodiment, the first preset width is 1.5 mm.

[0072] In one embodiment, if Figure 6 As shown, when the groove 31 passes through one side of the functional layer 30 and the width of the groove 31 is greater than the first preset width, the edge banding strip 40 covered by the notch of the groove 31 is adsorbed on the bottom surface of the groove 31 .

[0073] In this case, the groove is a blind groove. When the width of the groove is greater than the first preset width, when the sheets are assembled based on the assembly vacuum process, the edge banding strip on the side where the groove is located will be attached to the inner side of the blind groove due to the negative pressure in the blind groove, thereby forming a physical barrier layer (see Figure 6 As shown), the functional layer is edge-sealed to protect the functional layer. Optionally, in one embodiment, the first preset width is 1.5 mm.

[0074] In one embodiment, the width of the groove on the functional layer may be 0.5 mm to 10 mm, but the width of the groove may be determined according to different edge sealing width requirements and the type of the blocked material.

[0075] In one embodiment, if Figure 1-Figure 7 As shown, the vacuum degree of the sealed cavity formed by the edge sealing strip 40 and the groove 31 is less than the preset vacuum degree. The setting standard of the preset vacuum degree is based on the principle that the sealed cavity can block the erosion of various substances on the functional layer. When the vacuum degree of the sealed cavity is less than the preset vacuum degree, the sealed cavity is considered to be a vacuum environment, which can be equivalent to a vacuum barrier layer to block the erosion of various substances on the functional layer.

[0076] In one embodiment, the sealed cavity is filled with a protective gas. The protective gas refers to a gas that does not react with the material of the functional layer, for example, it can be an inert gas such as nitrogen, helium, neon, argon and xenon.

[0077] In one embodiment, the edge banding is a flexible edge banding such as Figure 4As shown, when the groove 31 passes through two side surfaces of the functional layer 30 and the width of the groove 31 is less than or equal to the first preset width, the edge sealing strips 40 on both sides of the groove 31 are close to each other but not adsorbed to each other, and the edge sealing strips 40 on both sides and the groove 31 form a vacuum barrier layer.

[0078] For example, in one embodiment, the first preset width is 1.5 mm. If the width of the groove is greater than 1.5 mm, when the functional layer is assembled and evacuated, the groove is too narrow so that the edge strips on both sides cannot contact each other, and a small amount of air will remain in the groove to form a vacuum barrier layer (see Figure 4 shown).

[0079] In one embodiment, the edge banding is a flexible edge banding such as Figure 7 As shown, when the groove 31 passes through one side of the functional layer 30 and the width of the groove 31 is less than or equal to the first preset width, the edge sealing strip 40 at the notch is close to the bottom surface of the groove 31 but does not contact the bottom surface of the groove 31, and the edge sealing strip 40 and the groove 31 form a vacuum barrier layer.

[0080] For example, in one embodiment, the first preset width is 1.5 mm. If the width of the groove does not exceed 1.5 mm, when the functional layer is assembled and evacuated, the groove is too narrow so that the edge sealing strip on the notch side cannot contact the inner side of the groove, and a small amount of air will remain in the groove to form a vacuum barrier layer (see Figure 7 shown).

[0081] In one embodiment, for the flexible edge sealing strip, when the groove passes through the two sides of the functional layer and the width of the groove is greater than the first preset width, after the edge sealing strips on both sides are adsorbed against each other, the hollow area formed with the groove can also form a vacuum barrier layer.

[0082] In one embodiment, for the flexible edge sealing strip, when the groove passes through one side of the functional layer and the width of the groove is greater than the first preset width, after the edge sealing strip at the notch is adsorbed onto the bottom surface of the groove, the two hollow areas formed can also form a vacuum barrier layer.

[0083] In one embodiment, at least one of the first transparent substrate and the second transparent substrate comprises a single-layer or multi-layer glass plate. Based on the single-layer or multi-layer glass plate, a good protective effect can be formed on the functional layer. The laminated component formed based on the glass plate can be widely used on the installation substrate such as vehicles and buildings.

[0084] In one embodiment, the laminated component is a vehicle-mounted glass. Vehicle-mounted glass includes but is not limited to Figure 8 and Fig. 9 Side windows, sunroof, rear window, rearview mirror and windshield shown.

[0085] In one embodiment, when the laminated component is a vehicle-mounted glass, the thickness of the edge banding strip can be 10 μm to 200 μm. The edge banding thickness can be adjusted to meet different requirements for laminate thickness.

[0086] In one embodiment, when the laminated component is vehicle-mounted glass, the width of the edge banding strip can be 2 mm to 30 mm. The width of the edge banding strip can be adjusted to adapt to vehicle-mounted glass with different edge banding width requirements.

[0087] In one embodiment, if Figure 8-Figure 9 As shown, at least part of the laminated assembly 100 is embedded in the vehicle body, and the laminated assembly 100 is movable, and at least the edge region C of the functional layer 30 located outside the water line Q of the vehicle body has a groove 31 .

[0088] The laminated component is movable, which means that the laminated component can move relative to the vehicle body, and as the laminated component moves, the visible area exposed outside the vehicle body changes, such as Figure 8-Figure 9 As shown, in this case, the vehicle body water line Q outside refers to the maximum visible area S that can be exposed by the laminated component 100. Based on this, it can be ensured that the exposed visible area S of the laminated component 100 in any state during the movement adopts the narrow edge sealing method of the groove and the notch attached to the edge banding strip 40 mentioned in the above embodiment.

[0089] In one embodiment, the edge band is a rigid edge band. In this case, after the sheet is evacuated (vacuumed), Figure 1 , Figure 2 and Figure 5 As shown, the edge strip 40 does not deform, and the edge strip 40 and the groove 31 cooperate to form a vacuum area. A vacuum barrier layer is formed along the extension direction of the groove 31 to protect the functional layer 30 from being corroded by various substances in the environment.

[0090] The vacuum barrier layer and the physical barrier layer described in the above embodiments can both prevent the functional layer from being corroded by various substances in the environment, including but not limited to corrosion by water vapor, oxygen, plasticizers and the like.

[0091] Optionally, the area where the groove is opened may be an area on the functional layer where no function is implemented, that is, the setting of the groove does not affect the functional implementation of the functional layer.

[0092] In one embodiment, the functional layer may include at least one of a display, a dimming layer, and a temperature adjustment layer.

[0093] Among them, the display may be a display using LC (liquid crystal), LED (light-emitting diode), OLED (Organic Light-Emitting Diode), inorganic EL (Electroluminance), laser, and the like.

[0094] The dimming layer may include a first transparent medium layer, a first conductive layer, a dimming element, a second conductive layer, a second transparent medium layer, a first electrode connected to the first conductive layer, and a second electrode connected to the second conductive layer, which are stacked in sequence. Voltages can be applied to the first conductive layer and the second conductive layer respectively through the first electrode and the second electrode, thereby driving the dimming element.

[0095] Among them, the preparation materials of the dimming element may include but are not limited to PDLC (polymer dispersed liquid crystal), SPD (Suspended Particle Device), GHLC (Guest-Host Liquid Crystal) and EC (Electrochromic), photochromic materials and electrodynamic materials.

[0096] The first transparent medium layer and / or the second transparent medium layer may be made of a transparent resin material. For example, the transparent resin material may include at least one of polyethylene terephthalate (PET), polyethylene naphthalate, polyamide, polyether, polysulfone, polyethersulfone, polycarbonate, polyarylate, polyetherimide, polyetherether copper, polyimide, aramid, polybutylene terephthalate, triacetyl cellulose, polyurethane and cycloolefin polymer.

[0097] The first conductive layer and / or the second conductive layer may be made of transparent conductive oxide (TCO), which may include but is not limited to tin-doped indium oxide (ITO), aluminum-doped zinc oxide (AZO), and indium-doped cadmium oxide.

[0098] The first conductive layer and / or the second conductive layer may also be made of transparent conductive polymers such as poly(3,4-ethylenedioxythiophene: PEDOT) or poly(4,4-dioctylcyclopentadithiophene).

[0099] The first conductive layer and / or the second conductive layer may also be a laminated film of a metal layer and a dielectric layer, silver nanowires, and a silver or copper metal mesh.

[0100] The temperature adjustment layer may include an infrared absorption layer and a temperature adjustment reflective layer, wherein the infrared absorption layer is arranged closer to the ambient light than the temperature adjustment reflective layer. The temperature adjustment reflective layer may include materials such as vanadium dioxide.

[0101] By adopting the edge sealing method of the edge sealing strip combined with the edge groove introduced in the above embodiment, it can be ensured that the dimming layer is not corroded by substances such as water, oxygen and plasticizers in the film, and the narrow edge sealing design of the stacked component can be achieved. Under this edge sealing method, there is no need for external edge sealing strips, and the edge filling width of the outer edge of the dimming layer will not be reduced, which is conducive to rapid assembly and improved production efficiency.

[0102] In one embodiment, if Figure 2-Figure 7 As shown, the stacked assembly 100 further includes an adhesive layer 50 .

[0103] The adhesive layer 50 is located between the first transparent substrate 10 and the second transparent substrate 20 , and the adhesive layer 50 covers the functional layer 30 and the edge banding 40 .

[0104] The laminated component 100 provided in the embodiment of the present application, by opening a groove 31 in the edge area of ​​the functional layer 30, does not occupy the edge filling area B outside the functional layer 30, and can be coated with glue on both sides of the functional layer 30 covered with the edge band 40, and the edge filling area B of the outer contour of the functional layer 30, so as to form an adhesive layer 50 covering the functional layer 30 and the edge band 40, and bond the first transparent substrate 10 and the second transparent substrate 20. The specific implementation process can refer to the process in the process of the laminated component multilayer structure assembly operation, which is not repeated here. The adhesive layer may include multiple adhesive layers, for example, it may include an adhesive layer in the edge filling area, an adhesive layer located between the functional layer and the first transparent substrate, and an adhesive layer located between the functional layer and the second transparent substrate.

[0105] In one embodiment, if Figure 8-Figure 9 As shown, the shape of the edge strip 40 matches the outer contour of the edge area of ​​the corresponding functional layer 30. That is, the shape of the edge strip 40 is the imitation of the edge of the functional layer 30.

[0106] When the edge region of the functional layer is cut to form the above-mentioned groove, the cutting pattern of the groove can be designed according to the size profile of the stacked component and the edge shape of the functional layer. Optionally, the shape of the edge of the functional layer matches the edge shape of the first transparent substrate and the second transparent substrate, for example, the edge of the first transparent substrate and the edge of the second transparent substrate are aligned, and the edge of the functional layer is parallel to the first transparent substrate and the second transparent substrate, respectively.

[0107] In one embodiment, if Figure 1-Figure 7As shown, one side of the edge strip 40 is aligned with the outer contour of the corresponding edge region of the functional layer 30 .

[0108] The edge of the functional layer can be used as a positioning device for the edge banding strip, and the outer contour edge of the edge banding strip at the notch is aligned with the outer contour edge of the functional layer.

[0109] The laminated component provided in the embodiment of the present application realizes edge sealing of the functional layer by opening a groove at least in the edge area of ​​the functional layer in the user-visible area, and covering the notch of the groove with an edge sealing strip. The position of the edge sealing strip does not need to exceed the edge of the functional layer. Only a precision cutting machine or laser cutting equipment is used to cut through or half-cut a groove at a specific position of the edge of the functional layer. The edge of the functional layer is then used as a limit for the edge sealing strip, and a narrow and transparent edge sealing strip is covered on the notch of the groove on the functional layer. The sheets are then assembled and evacuated. A barrier layer will be formed in the groove area to achieve the effect of blocking water, oxygen, plasticizers and other substances in the environment, thereby completing high-quality edge sealing of the functional layer.

[0110] In one embodiment, a method for preparing a laminated assembly is also provided to prepare the laminated assembly 100 in the above embodiment. Fig.10 As shown, the preparation method of the stacked assembly includes:

[0111] S120: providing a functional layer;

[0112] S140: cutting at least a portion of the edge region of the functional layer to form a groove that penetrates at least one side of the functional layer;

[0113] S160: Cover the edge banding strip at the notch of the groove;

[0114] S180: providing a first transparent substrate and a second transparent substrate, and combining the functional layer covered with the edge band with the first transparent substrate and the second transparent substrate on both sides based on a combination and vacuuming process to form a laminated component.

[0115] The preparation method of the laminated component provided in the embodiment of the present application is to cut a groove in at least a part of the edge area of ​​the functional layer to form a groove that passes through at least one side of the functional layer, and cover the groove with an edge strip, and cooperate with the provided first transparent substrate and second transparent substrate to perform a lamination and degassing process, and the functional layer covered with the edge strip is laminated with the first transparent substrate and the second transparent substrate on both sides, and a vacuum barrier layer and / or a physical barrier layer is formed in the area formed by the groove, so as to form a laminated component product with a narrow edge seal in the visible area of ​​the above embodiment.

[0116] Specifically, in order to better illustrate the implementation process of the preparation method provided in the embodiment of the present application, a specific example is used here for illustration:

[0117] First, CAD (Computer Aided Design) film cutting graphics can be designed according to the size, outline of the first transparent substrate and the second transparent substrate and the size and position of the functional layer, and then a cutting wheel or laser is used for precision cutting to cut out the through grooves on the functional layer and the corresponding contoured edge banding strips. The outer edge contour of the contoured edge banding strip is aligned with the outer contour of the functional layer, and the edge banding strip is fixed at the notch of the groove by adhesive adhesion, electrostatic adsorption or local adhesive tape to prevent the edge banding strip from sliding out of position; repeat the above operation to complete the fixing of the edge banding strips at all notch positions. Figure 8-Figure 9 As shown in the non-visible area NS, since this position is invisible to the user, the edge sealing of the functional layer in the area NS can continue to adopt the narrow edge sealing method in the above embodiment, or other traditional edge sealing methods can be adopted. For the non-visible area NS, no matter which functional layer edge sealing method is adopted, after all edges of the functional layer 30 are edge sealed, the functional layer 30 can be combined.

[0118] In one embodiment, when the groove passes through one side of the functional layer, before the step S160 of covering the edge banding strip at the notch of the groove, as shown in FIG. Fig.11 As shown, the method for preparing the stacked assembly also includes:

[0119] S150: Cleaning the liquid crystal in the groove until there is at least a smooth liquid crystal-free strip of a second preset width in the groove.

[0120] The edge of the functional layer forms a groove structure after fine cutting by a knife wheel or half cutting by a laser. At this time, the blind groove needs to be cleaned of liquid crystal. Cleaning methods such as manual wiping of the liquid crystal or laser cleaning of the liquid crystal can be used, and at least a second preset width and uniform smooth liquid crystal-free band must be ensured in the groove to ensure the barrier effect of the barrier layer formed after subsequent assembly and vacuuming.

[0121] The outer edge of the edge banding is aligned with the outer contour of the functional layer, and the edge banding is fixed at the groove by gluing, electrostatic adsorption or local bonding with tape to prevent the edge banding from sliding and moving. Only the side of the functional layer where the groove is located is covered with the edge banding.

[0122] In one embodiment, when the laminated component is vehicle-mounted glass, the second preset width may be 1 mm.

[0123] The preparation method of the laminated component provided in the embodiment of the present application uses a precision cutting machine or laser equipment to perform precision cutting and grooving on at least part of the edge area of ​​the functional layer, uses the edge of the functional layer as the positioning of the edge banding strip, and sticks the edge banding strip to the groove of the functional layer. By closing the sheets and evacuating the air, a vacuum barrier layer or a physical isolation layer is formed in the groove to achieve the effect of blocking the erosion of external environmental substances. The laminated component prepared by the preparation method provided in the above embodiment has narrow edge sealing and simple structural process, which is conducive to improving production efficiency and reducing production costs.

[0124] It should be understood that, although the various steps in the figure are shown in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear description in this article, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a part of the steps in the figure may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0128] In one embodiment, the laminated component is a side window glass, and the laminated component can be raised and lowered. For example, the side window glass includes a front side window glass and a rear side window glass.

[0129] In an alternative approach, Figure 8-Figure 9As shown, when the laminated assembly 100 can be raised or lowered, the groove in the above embodiment can be opened in the edge area C of the functional layer 30 corresponding to the laminated assembly area (visible area S) above the vehicle body water tangent line Q, so that the functional layer 30 in the user-visible area S during the lifting and lowering of the laminated assembly 100 is all designed with narrow edge sealing, on the one hand, reducing the impact on the transmittance, and on the other hand, reducing the impact of the edge sealing on the user's field of vision. Optionally, using a transparent edge sealing strip can further improve the effect of transmittance and field of vision.
