Description

Technical Field

[0001] The utility model relates to the technical field of glass, specifically Background Technique

[0002] Laminated glass is a composite glass product in which two or more pieces of glass are sandwiched with one or more layers of organic polymer interlayers and permanently bonded together through special technological treatment. Laminated glass has the advantages of sound insulation, heat insulation, ultraviolet resistance, etc., and is widely used in fields such as architecture and automobiles, bringing convenience and safety to people's lives.

[0003] The existing laminated glass is usually directly bonded by two pieces of glass. When the laminated glass is applied in an environment with high humidity, the laminated glass bonded by two pieces of glass has poor moisture-proof performance, and water vapor is likely to enter the glass interlayer to generate water mist, affecting its use effect. Moreover, the laminated glass directly bonded by two pieces of glass has poor impact resistance, and the laminated glass is easily broken and damaged. Therefore, we propose a moisture-proof laminated glass. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1:

[0020] Please refer to Figures 1-3, the utility model provides a technical solution: a moisture-proof laminated glass, which includes a frame 1. In the middle of the inner cavity of the frame 1, a middle glass 8 is installed. On both sides of the middle glass 8, an outer glass 2 and an inner glass 5 are respectively connected. Anti-explosion films 9 are provided on the inner side surfaces of the outer glass 2 and the inner glass 5. And buffer layers are provided between both ends of the middle glass 8 and the two groups of anti-explosion films 9. Outer flexible polyurethane layers 4 and inner flexible polyurethane layers 6 are respectively provided on the outer side surfaces of the outer glass 2 and the inner glass 5. Sealing rubber strips 7 are installed between the middle glass 8, the outer glass 2, the inner glass 5 and the inner wall of the frame 1. Silicone gaskets 3 are provided at the joints of the frame 1 with the outer glass 2 and the inner glass 5.

[0021] The silicone gaskets 3 and the sealing rubber strips 7 improve the sealing performance of the connection between the frame 1 and the outer glass 2, the middle glass 8, and the inner glass 5. And the silicone gaskets 3, the sealing rubber strips 7, and the middle glass 8 made of polymethyl methacrylate material all have certain water absorption properties, improving the moisture-proof performance of the laminated glass and preventing moisture from entering the glass interlayer. The outer flexible polyurethane layers 4 and the inner flexible polyurethane layers 6 are transparent themselves, making the laminated glass have buffering and shock-absorbing functions. The two groups of anti-explosion films 9 can stick the places where the glass breaks, reducing the flying of glass fragments and avoiding potential safety hazards. The buffer layer improves the buffering performance and impact resistance of the laminated glass, extending the service life of the laminated glass.

[0022] Among them, preferably, the buffer layer includes multiple groups of elliptical rubber pads 10, and both ends of the elliptical rubber pads 10 are respectively connected to the outer side surface of the anti-explosion film 9 and the outer side surface of the middle glass 8. Buffer glue 11 is filled between adjacent elliptical rubber pads 10. The elliptical rubber pads 10 are made of transparent elastic rubber. The elliptical rubber pads 10 with an elliptical cross-section have good elasticity and can quickly recover deformation. The buffer glue 11 improves the buffering performance and impact resistance of the laminated glass, preventing the laminated glass from directly breaking when stressed and extending the service life of the laminated glass.

[0023] Preferably, the middle glass 8 is made of polymethyl methacrylate material, and the anti-explosion film 9 is made of PET material. The polymethyl methacrylate material is a kind of lightweight, inexpensive, and easy-to-mold organic glass with good light transmittance and hygroscopicity, which can avoid the condensation of water droplets in the laminated glass to a certain extent.

[0024] Preferably, the elliptical rubber pads 10 have an elliptical cross-section and are transparent.

[0025] Preferably, the buffer glue 11 is PVB glue, and the frame 1 is made of stainless steel. The PVB glue has good adhesion, can stably bond the middle glass 8 with the elliptical rubber pads 10 and the anti-explosion layer 9 together, and can also absorb impact energy. The frame 1 made of stainless steel has good corrosion resistance and extends the service life of the frame 1.

[0026] Example 2:

[0027] Refer to Figure 1 The difference between this example and the first example is that the outer surface of the frame 1 is coated with an anti-corrosion layer; the anti-corrosion layer has a protective effect to prevent the frame 1 from rusting due to the influence of water vapor, and extends the service life of the frame 1.

[0028] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
