Description

Technical Field

[0001] This utility model relates to the field of transparent sheet manufacturing technology, specifically to a transparent sheet with crystal edge sealing and a car window. Background Technology

[0002] Currently, the glass produced and used includes laminated glass and tempered glass. Laminated glass consists of a transparent plastic film, such as polyvinyl butyral or ethylene-vinyl acetate copolymer, sandwiched between two pieces of glass, bonding them together. Tempered glass is primarily produced by mixing materials in a specific ratio, melting them at high temperatures in a furnace, and then allowing the molten glass to float on the surface of the molten tin. Under the combined action of the buoyancy of the molten tin, the weight of the molten glass, and surface tension, it is thinned and flattened. Regardless of whether it's laminated glass, tempered glass, or other types of glass, the edges are exposed. These exposed edges are prone to breakage due to impacts during use. Some exposed glass edges require grinding before use, resulting in a dull and less refined finish. Furthermore, the current glass assemblies have large profile tolerances, making them susceptible to crushing by the mold during injection molding as inserts. The current glass also exhibits weak acoustic isolation capabilities in the low-to-mid frequency band below 2000Hz. Utility Model Content

[0003] The problems solved by this utility model are: the exposed edges of transparent sheets leading to easy breakage and the need for polishing resulting in poor texture; and the large tolerance of the assembly outline and weak sound insulation.

[0004] To solve the above problems, this utility model provides a transparent sheet material with crystal edge sealing and a car window.

[0005] In a first aspect, the present invention provides a transparent sheet material with crystal edge sealing, comprising a transparent sheet material body and a transparent polymer material layer stacked together, wherein at least one end of the transparent sheet material body is provided with a transparent polymer material crystal edge sealing layer, and the transparent polymer material layer and the transparent polymer material crystal edge sealing layer are connected.

[0006] Optionally, the transparent polymer material layer is a transparent polyurethane layer, a transparent acrylic resin layer, a transparent silicone layer, or a transparent epoxy resin layer, and the thickness of the transparent polymer material layer is 0.5 mm to 3.0 mm; the transparent polymer material crystal edge sealing layer is a transparent polyurethane crystal edge sealing layer, a transparent acrylic resin crystal edge sealing layer, a transparent silicone crystal edge sealing layer, or a transparent epoxy resin crystal edge sealing layer, and the thickness of the transparent polymer material crystal edge sealing layer does not exceed 2.0 mm.

[0007] Optionally, the Shore A hardness rating of the transparent polymer material layer and the transparent polymer material crystal edge-sealing layer is 5 to 90.

[0008] Optionally, the transparent sheet body includes a first interlayer transparent sheet and a second interlayer transparent sheet, which are arranged in parallel layers. The first interlayer transparent sheet, the transparent polymer material layer, and the second interlayer transparent sheet are stacked in sequence, and the same end of the first interlayer transparent sheet and the second interlayer transparent sheet is covered by a transparent polymer material crystal edge sealing layer.

[0009] Optionally, the transparent sheet body includes a single-layer transparent sheet body, and a transparent polymer material layer is disposed on one side surface of the single-layer transparent sheet body.

[0010] Optionally, the end of the transparent sheet body with a transparent polymer crystal edge-sealing layer is an arc shape that protrudes towards the transparent polymer crystal edge-sealing layer.

[0011] Optionally, the end of the transparent polymer crystal edge sealing layer away from the transparent sheet body is square, and the distance between the side of the transparent polymer crystal edge sealing layer away from the transparent sheet body and the midpoint of the arc at the end of the transparent sheet body is 0.5mm to 2.0mm.

[0012] Optionally, the end of the transparent polymer crystal edge-sealing layer away from the transparent sheet body is square, and the side of the transparent polymer crystal edge-sealing layer away from the transparent sheet body is flush with the midpoint of the arc at the end of the transparent sheet body.

[0013] Optionally, the end of the transparent polymer crystal edge-sealing layer furthest from the transparent sheet body is arc-shaped, and the distance between the midpoint of the arc-shaped end of the transparent polymer crystal edge-sealing layer and the midpoint of the arc-shaped end of the transparent sheet body is 0.5mm to 2.0mm. (Utility Model)

[0014] Secondly, this utility model provides a vehicle window, including a frame and a transparent sheet with crystal edging as described in any of the above claims. The frame has a positioning part inside, and at least part of the end of the transparent sheet body with a transparent polymer crystal edging layer is embedded in the positioning part.

[0015] The beneficial effects of this utility model of a transparent sheet material with crystal edge sealing and a car window are as follows: Because the molecular chains of the transparent polymer material contain active groups such as isocyanate (-NCO), they can chemically react with the hydroxyl groups (-OH) on the surface of the transparent sheet material to form covalent bonds, firmly bonding the transparent polymer material and the transparent sheet material together; one side surface of the transparent sheet material body is provided with a transparent polymer material layer, which has good sound insulation capabilities, enhancing the transparent sheet material's ability to isolate noise below 2000Hz in the mid-to-low frequency range; at least one end of the transparent sheet material body is provided with a transparent polymer material crystal edge sealing layer, which, after edge sealing, results in an aesthetically pleasing appearance and provides protection, preventing the edges of the transparent sheet material from... It is easily cracked, and the transparent polymer crystal edge-sealing layer at the end also enhances the brightness of the end, giving it a "crystal texture" and improving its overall quality. Due to the presence of the transparent polymer layer and the transparent polymer crystal edge-sealing layer, when there is a deviation in the size and outline of the transparent sheet body, the transparent polymer layer and the transparent polymer crystal edge-sealing layer can absorb the deviation in the size and outline of the transparent sheet body. For example, when the size of the transparent sheet body is too large, the thickness of the corresponding transparent polymer layer and the transparent polymer crystal edge-sealing layer will be reduced accordingly, improving the accuracy of the assembly outline. When the transparent sheet with crystal edge-sealing is used as an insert for edge-sealing injection molding, the edge of the transparent sheet is not easily crushed by the mold.

[0033] To address the problems existing in the aforementioned related technologies, this embodiment provides a transparent sheet material with crystal edge sealing and a car window.

[0034] like Figure 1 , Figure 4 and Figure 6 As shown in the figure, the present invention provides a transparent sheet material with crystal edge sealing, comprising a transparent sheet material body 1 and a transparent polymer material layer 2 stacked together. At least one end of the transparent sheet material body 1 is provided with a transparent polymer material crystal edge sealing layer 3, and the transparent polymer material layer 2 and the transparent polymer material crystal edge sealing layer 3 are connected.

[0035] In this embodiment, because the molecular chain of polyurethane, a transparent polymer material, contains active groups such as isocyanate (-NCO), it can chemically react with the hydroxyl groups (-OH) on the surface of the glass plate to form covalent bonds, firmly bonding the polyurethane and glass together. A transparent polymer material layer 2 is provided on one side of the transparent plate body 1. This polymer material has good sound insulation capabilities, enhancing the transparent plate's ability to isolate noise below 2000Hz in the mid-to-low frequency range. At least one end of the transparent plate body 1 is provided with a transparent polymer crystal edge-sealing layer 3. After sealing the edge, the transparent plate has an aesthetically pleasing appearance and provides protection, making the edge of the transparent plate less prone to breakage. Furthermore, the end is wrapped with a transparent polymer crystal edge-sealing layer. The addition of the crystal edge-sealing layer 3 further enhances the brightness of the end, giving it a "crystal texture" and improving its overall quality. Due to the presence of the transparent polymer material layer 2 and the transparent polymer crystal edge-sealing layer 3, when there is a deviation in the size and outline of the transparent sheet body 1, the transparent polymer material layer 2 and the transparent polymer crystal edge-sealing layer 3 can absorb the deviation in the size and outline of the transparent sheet body 1. For example, when the size of the transparent sheet body 1 is too large, the thickness of the corresponding transparent polymer material layer 2 and the transparent polymer crystal edge-sealing layer 3 will be reduced accordingly, improving the accuracy of the assembly outline. When the transparent sheet with crystal edge-sealing is used as an insert for edge-sealing injection molding, the edge of the transparent sheet is less likely to be crushed by the mold.

[0036] Specifically, the transparent sheet body 1 can be a transparent sheet-like object made of transparent materials such as transparent glass, transparent polycarbonate (PC) solid sheet, or transparent acrylic sheet. Transparent polycarbonate (PC) solid sheet or transparent acrylic sheet can be used in place of glass. The transparent polymer material layer 2 and the transparent polymer material crystal sealing layer 3 can both be prepared using one or more of the following transparent polymer materials: polyurethane, acrylic resin, silicone, and epoxy resin.

[0037] In possible implementations, the transparent polymer material layer is a transparent polyurethane layer, a transparent acrylic resin layer, a transparent silicone layer, or a transparent epoxy resin layer, and the thickness of the transparent polymer material layer 2 is 0.5 mm to 3.0 mm; the transparent polymer material crystal sealing layer is a transparent polyurethane crystal sealing layer, a transparent acrylic resin crystal sealing layer, a transparent silicone crystal sealing layer, or a transparent epoxy resin crystal sealing layer, and the thickness of the transparent polymer material crystal sealing layer 3 does not exceed 2.0 mm.

[0038] Specifically, the thickness of the transparent polymer material layer 2 can be understood as the distance between the side surface of the transparent polymer material layer 2 away from the transparent sheet body 1 and the side surface of the transparent sheet body 1 close to the transparent polymer material layer 2; the thickness of the transparent polymer material crystal edge sealing layer 3 can be understood as the distance between the side surface of the transparent polymer material crystal edge sealing layer 3 away from the transparent sheet body 1 and the side surface of the transparent sheet body 1 close to the transparent polymer material crystal edge sealing layer 3.

[0039] In a possible implementation, the Shore A hardness rating of the transparent polymer material layer 2 and the transparent polymer material crystal sealing layer 3 is 5 to 90.

[0040] In this embodiment, the hardness of the polymer material should not be too hard. The hardness level is manufactured according to shore A 5 to shore A90, which enables the polymer material to have good sound insulation ability.

[0041] In possible implementations, such as Figure 7 , Figure 10 and Figure 12 The transparent sheet body 1 includes a first sandwich transparent sheet 11 and a second sandwich transparent sheet 12 in parallel. The first sandwich transparent sheet 11, the transparent polymer material layer 2 and the second sandwich transparent sheet 12 are stacked in sequence. The same side end of the first sandwich transparent sheet 11 and the second sandwich transparent sheet 12 is covered by a transparent polymer material crystal edge sealing layer 3.

[0042] In this embodiment, a transparent polymer material layer 2 is formed by injection molding a transparent polymer material between the first sandwich transparent plate 11 and the second sandwich transparent plate 12. The process is simple, low-cost, and economically efficient, and the transparent polymer material layer 2 obtained by injection molding is free of air bubbles.

[0043] Optionally, the transparent sheet body 1 includes a single-layer transparent sheet body 1, and a transparent polymer material layer 2 is disposed on one side surface of the single-layer transparent sheet body 1.

[0044] Optionally, the end of the transparent plate body 1 with the transparent polymer crystal edge sealing layer is an arc shape that protrudes towards the transparent polymer crystal edge sealing layer 3.

[0045] As stated above, in possible implementations, such as Figure 1 and Figure 7 As shown, the end of the transparent polymer crystal edge sealing layer 3 away from the transparent plate body 1 is square, and the distance between the side of the transparent polymer crystal edge sealing layer 3 away from the transparent plate body 1 and the midpoint of the arc at the end of the transparent plate body 1 is 0.5mm to 2.0mm.

[0046] As stated above, in possible implementations, such as Figure 4 and Figure 10 As shown, the end of the transparent polymer crystal edge sealing layer 3 away from the transparent plate body 1 is square, and the side of the transparent polymer crystal edge sealing layer 3 away from the transparent plate body 1 is flush with the midpoint of the arc at the end of the transparent plate body 1.

[0047] As stated above, in possible implementations, such as Figure 6 and Figure 12 As shown, the end of the transparent polymer crystal edge sealing layer 3 that is away from the transparent plate body 1 is arc-shaped, and the distance between the midpoint of the arc-shaped end of the transparent polymer crystal edge sealing layer 3 and the midpoint of the arc-shaped end of the transparent plate body 1 is 0.5mm to 2.0mm.

[0048] This utility model provides a method for preparing a transparent sheet with crystal-sealed edges, used to prepare a transparent sheet with crystal-sealed edges as described in any of the preceding claims, comprising the following steps:

[0049] Select an injection mold with a hollow cavity, place the transparent sheet body 1 inside the hollow cavity, and inject transparent polymer material onto one side surface and at least one end of the transparent sheet body 1 by injection molding. A transparent polymer material layer 2 is formed on one side surface of the transparent sheet body 1, and a transparent polymer material crystal edge sealing layer 3 is formed at least one end of the transparent sheet body 1.

[0050] In this embodiment, because the molecular chains of the transparent polymer material contain active groups such as isocyanate (-NCO), which can chemically react with the hydroxyl groups (-OH) on the surface of the transparent sheet to form covalent bonds, the transparent polymer material and the transparent sheet are firmly bonded together. A transparent polymer material layer 2 is provided on one side of the transparent sheet body 1. The polymer material has good sound insulation capabilities, enhancing the transparent sheet's ability to isolate noise below 2000Hz in the mid-to-low frequency range. At least one end of the transparent sheet body 1 is provided with a transparent polymer crystal edge-sealing layer 3. After sealing the edge of the transparent sheet, the appearance is aesthetically pleasing and it provides protection, making the edge of the transparent sheet less prone to cracking. Furthermore, the end is wrapped with a transparent polymer crystal edge-sealing layer. The addition of the crystal edge-sealing layer 3 further enhances the gloss of the ends, giving them a "crystal-like" texture and improving their overall quality. Due to the presence of the transparent polymer material layer 2 and the transparent polymer crystal edge-sealing layer 3, when there are deviations in the dimensional outline of the transparent sheet body 1, these layers can absorb the deviations. For example, if the transparent sheet body 1 is too large, the corresponding thickness of the transparent polymer material layer 2 and the transparent polymer crystal edge-sealing layer 3 will decrease, improving the accuracy of the assembly outline. When the transparent sheet with crystal edge-sealing is used as an insert for edge molding, the edges of the transparent sheet are less likely to be crushed by the mold. The transparent polymer material layer 2 and the transparent polymer crystal edge-sealing layer 3 are formed through injection molding, a simple process with low cost and high economic benefits. Furthermore, the injection-molded transparent polymer material layer 2 and the transparent polymer crystal edge-sealing layer 3 are bubble-free.

[0051] In possible implementations, transparent polymer materials include, but are not limited to, transparent two-component polymer materials or thermoplastic transparent polymer materials.

[0052] Optionally, the Reynolds number of the transparent polymer material flow is below 2400.

[0053] In this optional embodiment, when the Reynolds number of the transparent polymer material flow is below 2400, the flow of the transparent polymer material can always be in a laminar state, and it is not easy for air bubbles to be entrained during the material flow. If turbulence is generated, air bubbles are easily entrained during the material flow.

[0054] Optionally, the injection speed of the transparent polymer material is 130 mm / s to 800 mm / s, and the end of the transparent plate body 1 forming the transparent polymer crystal edge sealing layer 3 is 0.5 to 2.0 mm away from the inner wall of the hollow cavity near the transparent polymer crystal edge sealing layer 3.

[0055] In this optional embodiment, to prevent the filling time of the transparent polymer material from being too long, which would affect the continued filling of the product and cause appearance problems, while also taking into account the pressure bearing limit of the manufacturing equipment, the pouring speed is controlled at 130-800mm / s and the thickness of the transparent polymer material layer 2 is controlled within the range of 0.5mm to 3.0mm. In this way, the flow of the transparent polymer material can ensure that air bubbles are not entangled in the product manufacturing process.

[0056] A 0.5-2mm transparent polymer crystal edge sealing layer 3 is reserved at the end of the transparent sheet. Therefore, a 0.5 to 2.0mm clearance is reserved between the end of the transparent sheet body 1 and the inner wall of the hollow cavity near the transparent polymer crystal edge sealing layer 3 to ensure that the sealing block at the edge of the transparent sheet end will not be damaged by the sealing block due to the excessive length of the transparent sheet body 1 during injection molding.

[0057] As described above, in a possible implementation, the transparent sheet body 1 includes a first sandwich transparent sheet 11 and a second sandwich transparent sheet 12 in parallel. A transparent polymer material is injection molded between the first sandwich transparent sheet 11 and the second sandwich transparent sheet 12 to form a transparent polymer material layer 2. A transparent polymer material crystal edge sealing layer 3 is formed on the same side end of the first sandwich transparent sheet 11 and the second sandwich transparent sheet 12. The first sandwich transparent sheet 11 and the second sandwich transparent sheet 12 are spaced 0.5 to 3.0 mm apart.

[0058] In this possible implementation, the edge-sealed sandwich transparent sheet is prepared by injection molding, which is a simple process with low cost and high economic benefits. The transparent sheet is bubble-free during injection molding.

[0059] Furthermore, the method also includes the step of: cutting the transparent polymer crystal edge sealing layer 3 so that the transparent polymer crystal edge sealing layer 3 is flush with the end of the transparent sheet body 1 or the transparent polymer crystal edge sealing layer 3 is arc-shaped.

[0060] In this possible embodiment, if the customer does not require the end crystal sealing effect, the transparent polymer crystal sealing layer 3 can be cut off by tooling or fixtures. The edge can be cut into a flush or rounded edge. Compared with traditional sandwich transparent boards, the edge of the sandwich transparent board with transparent polymer crystal sealing layer 3 is neat and controllable, and there is no uneven edge appearance.

[0061] This utility model provides a vehicle window, such as Figure 2 , Figure 3 , Figure 5 , Figure 8 , Figure 9 and Figure 11As shown, it includes a frame 4 and a transparent sheet with crystal edge sealing as described in any of the above claims. The frame 4 has a positioning part 41 on its inner side, and the end of the transparent sheet body 1 with transparent polymer crystal edge sealing layer 3 is at least partially embedded in the positioning part 41.

[0062] The present invention will be further described below with reference to specific embodiments.

[0063] Example 1: Preparation of edge-sealed single-layer tempered glass.

[0064] like Figure 1 As shown, an injection mold with a hollow cavity is selected, and a single-layer tempered glass is placed in the hollow cavity. Transparent polyurethane is injected onto one side surface and at least one end of the transparent sheet body 1 by injection molding. A transparent polymer material layer 2 is formed on one side surface of the transparent sheet body 1, and a transparent polymer material crystal edge sealing layer 3 is formed at at least one end of the transparent sheet body 1. The transparent polymer material layer 2 and the transparent polymer material crystal edge sealing layer 3 are connected to obtain a single-layer tempered glass with an edge sealing.

[0065] like Figure 2 As shown, the inner side of the frame 4 of the vehicle corner window has a positioning part 41. One side of the single-layer tempered glass with a transparent polymer crystal edge sealing layer 3 is embedded in the positioning part 41 to obtain a vehicle corner window with edge sealing decoration. The edge of the corner window has a crystal texture.

[0066] like Figure 3 As shown, when the corner window of the vehicle does not require edge sealing, one side of the single-layer tempered glass with the transparent polymer crystal edge sealing layer 3 is completely embedded in the positioning part 41, and the transparent polymer crystal edge sealing layer 3 is completely covered.

[0067] like Figure 4 As shown, when the corner window of a vehicle does not require edge sealing, the transparent polymer crystal edge sealing layer 3 can be cut off, making it flush with the end of the transparent panel body 1. At this time, the minimum thickness of the transparent polymer crystal edge sealing layer 3 is equivalent to 0. Then, the side of the single-layer tempered transparent panel with the transparent polymer crystal edge sealing layer 3 is embedded into the positioning part 41, as shown. Figure 5 As shown.

[0068] like Figure 6 As shown, depending on the shape requirements of the transparent sheet with crystal edge sealing, the transparent polymer material crystal edge sealing layer 3 can also be cut into an arc shape.

Transparent polyurethane is injected into the space between the first sandwich transparent sheet 11 and the second sandwich transparent sheet 12 and at least one end of the space by injection molding. A transparent polymer material layer 2 is formed between the first sandwich transparent sheet 11 and the second sandwich transparent sheet 12. A transparent polymer material crystal edge sealing layer 3 is formed at at least one end of the first sandwich transparent sheet 11 and the second sandwich transparent sheet 12. The transparent polymer material layer 2 and the transparent polymer material crystal edge sealing layer 3 are connected to obtain a sealed sandwich transparent sheet.

[0071] like Figure 8 As shown, the inner side of the frame 4 of the vehicle corner window has a positioning part 41. One side of the transparent polymer crystal edge sealing layer 3 of the edge sealing sandwich transparent plate is embedded into the positioning part 41 to obtain a vehicle corner window with edge sealing decoration. The edge of the corner window has a crystal texture.

[0072] like Figure 9 As shown, when the corner window of the vehicle does not require edge sealing, one side of the transparent polymer crystal edge sealing layer 3 of the interlayer transparent plate of the edge sealing is completely embedded into the positioning part 41, and the transparent polymer crystal edge sealing layer 3 is completely covered.

[0073] like Figure 10 As shown, when the corner window of a vehicle does not require edge sealing, the transparent polymer crystal edge sealing layer 3 can be cut off so that it is flush with the end of the transparent panel body 1. Then, the side of the sandwich transparent panel with the transparent polymer crystal edge sealing layer 3 is embedded into the positioning part 41, as shown. Figure 11 As shown.

[0074] like Figure 12 As shown, depending on the shape requirements of the transparent sheet with crystal edge sealing, the transparent polymer material crystal edge sealing layer 3 can also be cut into an arc shape.

[0075] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
