Laminated assembly and preparation method therefor, and vehicle

Abstract

The present application relates to a laminated assembly and a preparation method therefor, and a vehicle. In the laminated assembly (100), under the laminated structure formed by stacking an edge sealing strip (40), a first transparent substrate (10), a second transparent substrate (20) and a functional layer (30), the width of a groove (31) can be designed as a narrow groove and is adapted for a laminated assembly (100) of any shape, thereby facilitating the implementation of a narrow edge sealing design while ensuring the flat attachment of the edge sealing and improving the quality of the edge sealing. In addition, the edge sealing strip (40) is not required to extend beyond the edge of the functional layer (30), which avoids reducing the edge compensation width at the periphery of the functional layer (30). The lamination assembly is easy to implement, facilitating an increase in the edge sealing processing speed.

[0044] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The embodiments of the present application are shown in the accompanying 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.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0046] It will be understood that when a layer is referred to as being "on" another layer, it can be directly on the other layer or intervening layers can also be present. In contrast, when an layer is referred to as being "directly on" another layer, then there are no intervening layers present. It will be understood that, although the terms first, second, etc. can be used herein to describe various layers, these layers should not be limited by these terms. These terms are only used to distinguish one layer from another. Thus, a first transparent substrate could be termed a second transparent substrate, and, similarly, a second transparent substrate could be termed a first transparent substrate - a first transparent substrate and a second transparent substrate are different transparent substrates.

[0047] As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise. It will be further understood that the terms "comprises", "comprising", "includes" and / or "including", or the like, when used in this specification, specify the presence of stated features, integers, steps, operations, elements, components, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

[0048] Functional glass such as light-adjustable glass has been increasingly applied in various scenarios such as automobiles, smart conference rooms, hotels, etc. For example, in the field of automobiles, a light-adjustable layer can be arranged in a vehicle laminated glass, and the light-adjustable layer is powered to adjust the light and view of the glass to meet the needs of users in different scenarios. When the light-adjustable layer is applied in the laminated glass, it is easy to be eroded by water vapor in the environment or small molecule plasticizers in the interlayer adhesive film. Therefore, the light-adjustable layer needs to be edge-sealed to block the erosion of various substances in the environment.

[0049] The edge sealing technology in the traditional technology includes Y-shaped edge sealing, U-shaped edge sealing, edge sealing adhesive, etc. Most of them are suitable for light-adjustable sunroof glass products. Since the four edges of the sunroof glass can be covered by the ink edge of the glass, and the sunroof is basically fixed and cannot be opened, the edge sealing of various light-adjustable layers in the vehicle cannot be visually observed. Unlike the sunroof glass, the side window glass can be lifted, and its top edge and at least part of the side edge are visible and exposed outside the vehicle body during lifting, which affects the light transmittance of the side window glass and affects the aesthetics. Therefore, there are more stringent specification size requirements for the appearance of the edge sealing of the exposed area.

[0050] If the Y-shaped edge sealing method in the traditional technology is used, the edge sealing strip needs to be extended outside the outer edge of the light adjusting layer, so that the width of the edge filling of the adhesive film of the middle layer is reduced, causing the laminating difficulty. The U-shaped edge sealing method is difficult to be flatly attached at the R-angle position of the vehicle window glass.

[0051] Based on this, in one embodiment, as shown in FIG. 1, a laminated assembly 100 is provided, comprising a first transparent substrate 10, a second transparent substrate 20 and a functional layer 30.

[0052] 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 penetrates one side of the functional layer 30, and the groove 31 is covered with an edge sealing strip 40, so that the edge sealing strip 40 and the groove 31 form a sealed cavity.

[0053] The first transparent substrate and the second transparent substrate refer to substrates with light transmission and can provide certain support. For example, the first transparent substrate and the second transparent substrate can be, but are not limited to, glass plates, transparent polyimide (PI) plates, transparent plastic plates, etc.

[0054] The functional layer refers to a film layer that can realize at least one function. For example, the functional layer can include, but is not limited to, a light response functional layer, a temperature adjusting layer, a silver plating layer and a low emissivity (LOW-E) layer. Taking the light response functional layer as an example, by changing the input electrical signal, the light transmittance, light absorption and light reflectance can be changed. For example, for the temperature adjusting layer, by changing the input electrical signal, the temperature of the laminated assembly can be changed. It should be understood that the functional layer in the present case includes the functional layer type that needs to be edge sealed and protected in the laminated assembly, and the type of the functional layer is not exhausted here.

[0055] The groove at least penetrating one side of the functional layer includes two cases:

[0056] When the groove penetrates two sides of the functional layer, a through groove is formed, and there are grooves on both sides of the functional layer. At this time, as shown in FIGS. 1-4, the edge sealing strip 40 covers both grooves on both sides of the functional layer 30.

[0057] When the groove penetrates one side of the functional layer, a blind groove is formed, and there is one groove. At this time, as shown in FIGS. 5-7, the edge sealing strip 40 covers the groove on one side of the functional layer 30.

[0058] For the selection of the at least partial edge region of the functional layer, the user can visually determine the region in combination with the application scenario of the laminated assembly. The "at least partial edge region of the functional layer" mentioned in the edge sealing mode based on the edge sealing strip in the above embodiment should at least include the user visually determinable region. For example, when the laminated assembly is a side window glass, the "at least partial edge region of the functional layer" should at least include the region above the water tangent of the vehicle body on the functional layer.

[0059] For the understanding of the covering of the notch by the edge sealing strip, reference can be made to Figs. 1-7. The edge sealing strip 40 is supported by the surface of the functional layer 30 on both sides of the notch 31, and the surface of the functional layer 30 is used as a support point to realize the covering of the notch.

[0060] As shown in Fig. 1, the laminated assembly 100 provided by 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 edge sealed to prevent the erosion of various substances in the environment. In the at least partial edge region of the functional layer 30, the edge sealing mode in the above embodiment is used for edge sealing. Specifically, at least one side of the functional layer 30 is provided with a groove 31, and the notch is covered with an edge sealing strip 40 to edge seal the functional layer 30. The sealed cavity formed by the groove 31 and the edge sealing strip 40 can protect the function of the functional layer 30 from the erosion of various substances in the environment. The laminated assembly 100 provided by the embodiment of the present application has an edge sealing strip 40, a transparent substrate (10 and 20), and a functional layer 30 in a laminated structure. The width of the groove 31 can be designed as a narrow groove, and the laminated assembly 100 can be adapted to any shape, which is beneficial to realize the narrow edge sealing design, ensure the flat attachment of the edge sealing, and improve the edge sealing quality.

[0061] In addition, under the structure that the edge sealing strip 40 covers the notch of the groove 31, the processing of the edge sealing strip 40 and the processing of the functional layer with the groove 31 can be performed synchronously. Then, the processed edge sealing strip 40 is covered on the notch 31. Compared with the traditional edge sealing material filling mode, the processing speed of the laminated assembly can be greatly improved.

[0062] The area of the functional layer is preferably smaller than the area of the first transparent substrate and the second transparent substrate. The edge sealing strip does not need to exceed the edge of the functional layer, which will not reduce the peripheral width of the functional layer, and the splicing is easy, which is beneficial to speed up the edge sealing processing speed.

[0063] It should be noted that the functional layer in the laminated assembly provided by the embodiments of the present application is edge-protected to isolate various substances in the environment from eroding it. In the above embodiments, the functional layer in part or all of the area of the laminated assembly can adopt the edge-protecting method to achieve narrow edge design in part or all of the area, i.e., the edge of the functional layer in the invisible area of the user can also adopt the edge-protecting method of the functional layer edge slot cooperating with the notch covered by the edge-protecting strip. As for the edge of the functional layer that is not protected by the edge-protecting method in the above embodiments, other edge-protecting methods can be used for edge protection, such as the Y-shaped edge-protecting method, the U-shaped edge-protecting method, and the like.

[0064] In one of the embodiments, the way in which the edge-protecting strip covers the functional layer includes but is not limited to electrostatic force adsorption, glue adhesion, and tape bonding.

[0065] In one of the embodiments, the edge-protecting strip is a transparent edge-protecting strip. The edge-protecting strip is made of transparent material, and the edge-protecting strip can be made of at least one of transparent materials such as epoxy adhesive, acrylate adhesive, polyurethane adhesive, and silicone adhesive. The edge-protecting strip formed by at least one of the above transparent materials is in the form of transparent adhesive film. Compared with the traditional white solidified glue method, the edge-protecting strip can avoid the problem of slow production rhythm caused by long processing time and the need for baking, thereby reducing production cost.

[0066] In some embodiments, the material of the edge-protecting strip can also be other transparent plastics other than the above examples, such as a rigid material such as polyester that can withstand a certain strain.

[0067] The laminated assembly provided by the embodiments of the present application at least in the user visible area of the laminated assembly has a groove in the edge area of the functional layer, and a transparent and barrier edge-protecting strip covers the notch area of the groove, without the need for external edge-protecting strips, to achieve transparent and beautiful, efficient, low-cost, and high-quality edge-protecting effect.

[0068] In one of the embodiments, the edge-protecting strip can have high-temperature resistance and / or low-temperature resistance to ensure the edge-protecting reliability of the laminated assembly in different temperature environments. For example, when the laminated assembly is vehicle-mounted glass, the material of the edge-protecting strip can withstand 150℃ high temperature for 1 hour without breaking or wrinkling, to ensure that the barrier effect of the edge-protecting strip is not affected when the vehicle is exposed to the sun for a long time, thereby ensuring the functional implementation reliability of the functional layer.

[0069] In one embodiment, the edge seal strip is a flexible edge seal strip, as shown in FIG. 3, FIG. 4, FIG. 6, FIG. 7, the edge seal strip 40 is recessed in the groove 31 based on the splicing vacuum process. When the splicing is performed by the splicing vacuum process, the area where the groove 31 is located forms a negative pressure environment, causing the edge seal strip 40 in the area of the groove 31 to bend and be recessed in the groove 31, so as to form a vacuum barrier layer and / or a physical barrier layer to protect the functional layer 30 from being eroded by various substances.

[0070] In one embodiment, for the flexible edge seal strip, as shown in FIG. 3, when the groove 31 penetrates both sides of the functional layer 30 and the width of the groove 31 is greater than the first preset width, the edge seal strips 40 on both sides of the groove 31 are adsorbed to each other.

[0071] The first preset width can be determined based on the depth of the groove and the elastic modulus of the flexible edge seal strip. The deeper the groove, the greater the first preset width, and the two are positively correlated. The smaller the elastic modulus of the flexible edge seal strip (the smaller the elastic modulus, the greater the deformation of the flexible edge seal strip under the same stress), the smaller the first preset width, and the two are positively correlated.

[0072] When the width of the groove is greater than the first preset width, the splicing is performed based on the splicing vacuum process, and the edge seal strips on both sides are adsorbed to each other due to the negative pressure existing in the through groove, and then are attached together to form a physical barrier layer (see FIG. 3), so as to protect the functional layer. Optionally, in one embodiment, the first preset width is 1.5 mm.

[0073] In one embodiment, as shown in FIG. 6, when the groove 31 penetrates one side of the functional layer 30 and the width of the groove 31 is greater than the first preset width, the edge seal strip 40 covered by the slot of the groove 31 is adsorbed to the bottom surface of the groove 31.

[0074] The groove in this case is a blind groove, and when the width of the groove is greater than the first preset width, the edge seal strip on one side of the slot is attached to the inside of the blind groove due to the negative pressure existing in the blind groove when the splicing is performed based on the splicing vacuum process, thereby forming a physical barrier layer (see FIG. 6) to protect the functional layer. Optionally, in one embodiment, the first preset width is 1.5 mm.

[0075] In one embodiment, the width of the groove on the functional layer can be 0.5 mm to 10 mm. However, the width of the groove can be determined according to different edge sealing width requirements and types of substances to be blocked.

[0076] In one embodiment, as shown in FIGS. 1-7, the vacuum degree of the sealed cavity formed by the edge seal 40 and the groove 31 is less than a preset vacuum degree. The preset vacuum degree is set based on the principle that the sealed cavity can block the erosion of various substances to 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 to the functional layer.

[0077] 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.

[0078] In one embodiment, the edge seal is a flexible edge seal. As shown in FIG. 4, when the groove 31 penetrates both sides of the functional layer 30 and the width of the groove 31 is less than or equal to a first preset width, the edge seals 40 on both sides of the groove 31 are close to each other but not adsorbed to each other, and the two edge seals 40 and the groove 31 form a vacuum barrier layer.

[0079] 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 subjected to lamination and air extraction, the edge seals on both sides of the groove cannot contact each other due to the excessive width of the groove, and a small amount of air remains in the groove to form a vacuum barrier layer (see FIG. 4).

[0080] In one embodiment, the edge seal is a flexible edge seal. As shown in FIG. 7, when the groove 31 penetrates one side of the functional layer 30 and the width of the groove 31 is less than or equal to a first preset width, the edge seal 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 seal 40 and the groove 31 form a vacuum barrier layer.

[0081] For example, in one embodiment, the first preset width is 1.5 mm. If the width of the groove is not more than 1.5 mm, when the functional layer is subjected to lamination and air extraction, the edge seal at the notch cannot contact the inside of the groove due to the excessive width of the groove, and a small amount of air remains in the groove to form a vacuum barrier layer (see FIG. 7).

[0082] In one embodiment, for a flexible edge seal, when the groove penetrates both sides of the functional layer and the width of the groove is greater than the first preset width, the edge seals on both sides are adsorbed to each other and the hollowed-out areas formed by the groove can also form a vacuum barrier layer.

[0083] In one embodiment, for a flexible edge seal, when the groove penetrates one side of the functional layer and the width of the groove is greater than the first preset width, the edge seal at the notch is adsorbed to the bottom surface of the groove, and the two hollowed-out areas formed thereby can also form a vacuum barrier layer.

[0084] In one embodiment, at least one of the first and second transparent substrates comprises a single or multi-layer glass sheet. Based on the single or multi-layer glass sheet, the functional layer can be well protected. The laminated assembly formed based on the glass sheet can be widely applied to the installation base of vehicles, buildings, etc.

[0085] In one embodiment, the laminated assembly is a vehicle glass. The vehicle glass includes, but is not limited to, side window glass, sunroof glass, rear window glass, rearview mirror glass, and front windshield glass as shown in FIGS. 8 and 9.

[0086] In one embodiment, when the laminated assembly is a vehicle glass, the edge seal strip can have a thickness of 10 μm to 200 μm. The thickness of the edge seal strip can be adjusted to meet different bonding thickness requirements.

[0087] In one embodiment, when the laminated assembly is a vehicle glass, the edge seal strip can have a width of 2 mm to 30 mm. The width of the edge seal strip can be adjusted to meet different bonding width requirements of the vehicle glass.

[0088] In one embodiment, as shown in FIGS. 8 and 9, at least part of the laminated assembly 100 is embedded in the vehicle body, and the laminated assembly 100 is movable. The edge region C of the functional layer 30 located at least outside the water tangent line Q of the vehicle body has a groove 31.

[0089] The movability of the laminated assembly means that the laminated assembly is movable relative to the vehicle body, and the visible area exposed outside the vehicle body changes with the movement of the laminated assembly. As shown in FIGS. 8 and 9, the area outside the water tangent line Q of the vehicle body refers to the maximum visible area S that can be exposed by the laminated assembly 100. Based on this, the exposed visible area S of the laminated assembly 100 in any state during movement can be ensured to adopt the narrow bonding mode of the groove cooperating with the notch and the edge seal strip 40 as mentioned in the above embodiments.

[0090] In one embodiment, the edge seal strip is a rigid edge seal strip. In this case, after the bonding and evacuation (vacuumization), the edge seal strip 40 does not deform as shown in FIGS. 1, 2 and 5. The edge seal strip 40 and the groove 31 cooperate to form a vacuum area, which forms a vacuum barrier along the extension direction of the groove 31 to protect the functional layer 30 from the erosion of various substances in the environment.

[0091] The vacuum barrier and the physical barrier introduced in the above embodiments can block the erosion of various substances in the environment to the functional layer, including but not limited to the erosion of water vapor, oxygen, plasticizer, etc.

[0092] Optionally, the area where the groove is opened can be an area on the functional layer where no function is implemented, i.e. the groove is arranged without affecting the function implementation of the functional layer.

[0093] In one of the embodiments, the functional layer can include at least one of a display, a light adjusting layer, and a temperature adjusting layer.

[0094] The display can be a display using LC (liquid crystal), LED (light-emitting diode), OLED (Organic Light-Emitting Diode), inorganic EL (Electroluminance), laser, etc.

[0095] The light adjusting layer can include a first transparent medium layer, a first conductive layer, a light adjusting 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, and a voltage can be applied to the first conductive layer and the second conductive layer through the first electrode and the second electrode, respectively, to drive the light adjusting element.

[0096] The light adjusting element can be made of a material including, but not limited to, PDLC (polymer dispersed liquid crystal), SPD (Suspended Particle Device), GHLC (Guest-Host Liquid Crystal), EC (Electrochromic), photochromic substance, and electrodynamic substance.

[0097] The first transparent medium layer and / or the second transparent medium layer can be made of a transparent resin material. For example, the transparent resin material can include at least one of PET (polyethylene terephthalate), polyethylene naphthalate, polyamide, polyether, polysulfone, polyethersulfone, polycarbonate, polyarylate, polyetherimide, polyether ether ketone, polyimide, aromatic polyamide, polybutylene terephthalate, triacetyl cellulose, polyurethane, and cyclic olefin polymer.

[0098] The first conductive layer and / or the second conductive layer can be made of a transparent conductive oxide (TCO). The transparent conductive oxide can include, but is not limited to, ITO (Tin-doped Indium Oxide), AZO (Aluminum-doped Zinc Oxide), and indium-doped cadmium oxide, etc.

[0099] The first conductive layer and / or the second conductive layer can also use a transparent conductive polymer such as poly(3,4-ethylenedioxythiophene): PEDOT, or poly(4,4-dioctylcyclopentadithiophene).

[0100] The first conductive layer and / or the second conductive layer can also use a laminated film of a metal layer and a dielectric layer, silver nanowires, and a metal mesh of silver or copper, etc.

[0101] The temperature adjustment layer can include an infrared absorption layer and a temperature adjustment reflection layer, and the infrared absorption layer is arranged closer to ambient light than the temperature adjustment reflection layer. The temperature adjustment reflection layer can include vanadium dioxide or other materials.

[0102] By using the edge sealing strip in the above embodiments in combination with the edge groove sealing method, the light adjustment layer can be protected from water, oxygen, plasticizers in the adhesive film, and other substances, and the narrow edge sealing design of the laminated assembly can be achieved. In this edge sealing method, the edge sealing strip does not need to be externally attached, and the edge sealing width of the light adjustment layer is not reduced, which is beneficial for rapid splicing and improves production efficiency.

[0103] In one embodiment, as shown in FIGS. 2-7, the laminated assembly 100 further includes an adhesive layer 50.

[0104] 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 sealing strip 40.

[0105] The laminated assembly 100 provided by the embodiments of the present application can open a groove 31 in the edge region of the functional layer 30, without occupying the edge sealing region B outside the functional layer 30. The two sides of the functional layer 30 covered with the edge sealing strip 40 and the edge sealing region B of the outer contour of the functional layer 30 can be coated with adhesive to form an adhesive layer 50 covering the functional layer 30 and the edge sealing strip 40, and bonding the first transparent substrate 10 and the second transparent substrate 20. The specific implementation process can be referred to the process in the splicing operation process of the laminated assembly multi-layer structure, which is not described here. The adhesive layer can include multiple adhesive layers, for example, an adhesive layer in the edge sealing region, an adhesive layer between the functional layer and the first transparent substrate, and an adhesive layer between the functional layer and the second transparent substrate.

[0106] In one embodiment, as shown in FIGS. 8-9, the shape of the edge sealing strip 40 matches the outer contour of the corresponding edge region of the functional layer 30. That is, the shape of the edge sealing strip 40 is a copy of the edge of the functional layer 30.

[0107] When the edge region of the functional layer is cut to form the groove, the cutting pattern of the groove can be designed according to the size profile of the laminated assembly and the shape of the edge of the functional layer. Alternatively, the shape of the edge of the functional layer matches the shape of the edge of the first transparent substrate and the second transparent substrate, for example, the edges of the first transparent substrate and 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.

[0108] In one embodiment, as shown in FIGS. 1-7, one side of the edge sealing strip 40 is aligned with the outer contour of the edge region of the corresponding functional layer 30.

[0109] The edge of the functional layer can be used as the positioning of the edge sealing strip, and the outer contour edge of the edge sealing strip at the notch is aligned with the outer contour edge of the functional layer.

[0110] The laminated assembly provided by the embodiments of the present application realizes the edge sealing of the functional layer by opening a groove in the edge region of the functional layer at least in the user visible area and covering the edge sealing strip at the notch of the groove. The position of the edge sealing strip does not need to exceed the edge of the functional layer. Only the edge of the functional layer is cut through or half-cut to form a groove at a specific position by using a precision cutting machine or a laser cutting device. Then, the edge of the functional layer is used as the limiting position of the edge sealing strip. A narrow and transparent edge sealing strip is covered on the notch of the groove of the functional layer. Then, lamination and air extraction are performed. The groove region forms a barrier layer to achieve the effect of blocking water, oxygen, plasticizer and other substances in the environment, thereby completing the high-quality edge sealing of the functional layer.

[0111] In one embodiment, a preparation method of a laminated assembly is also provided to prepare the laminated assembly 100 in the above embodiments. As shown in FIG. 10, the preparation method of the laminated assembly includes the following steps.

[0112] S120: providing a functional layer;

[0113] S140: cutting a groove at least through one side of the functional layer in at least part of the edge region of the functional layer;

[0114] S160: covering an edge sealing strip at the notch of the groove;

[0115] S180: providing a first transparent substrate and a second transparent substrate, and laminating the functional layer covered with the edge sealing strip and the first transparent substrate and the second transparent substrate on both sides based on a lamination and air extraction process to form a laminated assembly.

[0116] The preparation method of the laminated assembly provided by the embodiments of the present application cuts a groove in at least a partial edge region of the functional layer to form a groove that penetrates at least one side surface of the functional layer, covers the groove opening with a sealing strip, and performs a lamination and air extraction process in cooperation with the provided first transparent substrate and second transparent substrate to laminate the functional layer after covering the sealing strip with the first transparent substrate and second transparent substrate on both sides, form a vacuum barrier layer and / or a physical barrier layer in the area where the groove is located, and form a laminated assembly product with narrow sealing edges in the visible area in the above embodiments.

[0117] Specifically, to better illustrate the implementation process of the preparation method provided by the embodiments of the present application, a specific example is described herein:

[0118] First, a CAD (Computer Aided Design) film cutting pattern design is performed according to the size, profile of the first transparent substrate and second transparent substrate, and the size and position of the functional layer, and then a knife wheel or laser is used for fine cutting to cut a through groove on the functional layer and a corresponding profiled sealing strip. The outer edge profile of the profiled sealing strip is aligned with the outer profile of the functional layer, and the sealing strip is fixed at the groove opening by methods such as glue adhesion, electrostatic adsorption, or local adhesion with adhesive tape to prevent the sealing strip from sliding out of position; the above operation is repeated to complete the fixing of the sealing strip at all groove opening positions. As shown in FIGS. 8-9, the functional layer of the non-visible area NS is invisible to the user, and the functional layer sealing of the area NS can continue to use the narrow sealing method in the above embodiments, or other conventional sealing methods. For the non-non-visible area NS, regardless of the functional layer sealing method used, after all the edges of the functional layer 30 are sealed, the lamination operation of the functional layer 30 can be performed.

[0119] In one of the embodiments, in the case where the groove penetrates one side surface of the functional layer, before the step S160 of covering the groove opening with the sealing strip, as shown in FIG. 11, the preparation method of the laminated assembly further includes:

[0120] S150: cleaning the liquid crystal in the groove until there is a smooth liquid crystal-free band with a second preset width in the groove.

[0121] After the edges of the functional layer are subjected to knife wheel fine cutting or laser half cutting to form a groove structure, the blind groove needs to be cleaned of liquid crystal. Manual wiping of liquid crystal or laser equipment cleaning of liquid crystal can be used for cleaning, and at least a smooth liquid crystal-free band with a second preset width is ensured to ensure the barrier effect of the barrier layer formed after subsequent lamination and air extraction.

[0122] The outer edge of the edge sealing strip is placed in alignment with the outer contour of the functional layer, and the edge sealing strip is fixed at the notch by means of gluing, electrostatic adsorption or partial bonding by adhesive tape, so as to prevent the edge sealing strip from sliding, and the edge sealing strip covers only one side of the functional layer where the notch is located.

[0123] In one embodiment, when the laminated assembly is a vehicle glass, the second preset width can be 1mm.

[0124] The preparation method of the laminated assembly provided by the embodiments of the present application cuts and grooves at least part of the edge region of the functional layer by means of a cutting machine or a laser device, positions the edge sealing strip by means of the edge of the functional layer, pastes the edge sealing strip at the notch of the functional layer, forms a vacuum barrier layer or a physical isolation layer in the groove by means of air extraction, and achieves the effect of blocking the invasion of external environmental substances. The laminated assembly prepared by means of the preparation method provided by the above embodiments has a narrow edge sealing structure and simple process, which is beneficial to improving the production efficiency and reducing the production cost.

[0125] It should be understood that, although each step in the figure is displayed in sequence according to the direction of the arrow, these steps are not necessarily executed in the order indicated by the arrow. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other orders.
