Description

Technical Field

[0001] This utility model relates to the field of bent tempered glass technology, and in particular to a high-temperature resistant bent tempered glass. Background Technology

[0002] Curved tempered glass is a type of safety glass. Its production process is similar to that of ordinary tempered glass: the glass is first heated, then bent into the desired shape by its own weight or external pressure, and finally cooled rapidly and evenly. Curved tempered glass is significantly stronger than ordinary glass and also has excellent thermal shock resistance, able to withstand large temperature changes without breaking. Therefore, due to its unique properties and aesthetics, curved tempered glass is widely used in various fields such as architecture and interior decoration. For example, in architecture, it is often used in glass curtain walls to create unique architectural appearances; in interior decoration, it can be used as curved partitions to create a distinctive spatial atmosphere; in addition, curved tempered glass is also used for the outer casings of appliances such as washing machines and microwave ovens.

[0003] An existing patent (application number 202221075982.7) discloses an explosion-proof reinforced curved tempered glass, comprising an arc-shaped first tempered glass substrate and a second tempered glass substrate. The second tempered glass substrate is located inside the first tempered glass substrate, and an anti-blue light layer is disposed between the first and second tempered glass substrates. An outer explosion-proof layer for explosion-proof reinforcement is bonded to the first tempered glass substrate, and an inner explosion-proof layer for explosion-proof reinforcement is bonded to the inner side of the second tempered glass substrate. This invention uses two arc-shaped tempered glass substrates sandwiching an anti-blue light layer to form the main structure of the curved tempered glass, thereby reducing the impact of light and improving the overall explosion-proof strength. A sandwich reinforcement plate structure is designed within the inner and outer tempered glass substrates, and an explosion-proof layer with a buffer cavity is positioned and bonded to the surface to enhance the explosion-proof strength of the main structure of the curved tempered glass for use in harsh environments.

[0004] Existing curved tempered glass, especially single-layer curved tempered glass, has relatively poor compressive strength. In particular, during transportation, the lower curved space lacks a good supporting structure, making it prone to breakage under gravity. Utility Model Content

[0005] Therefore, it is necessary to provide a high-temperature resistant curved tempered glass to address the technical problem that single-layer curved tempered glass has relatively poor compressive strength, especially during transportation, where the lower curved space lacks a good support structure and is easily broken under gravity.

[0006] A high-temperature resistant bent tempered glass includes a bent tempered glass body. A protective device is fixedly installed at the front end of the bent tempered glass body. An installation device is fixedly installed at both the upper and lower ends of the bent tempered glass body. A support device is fixedly installed at the rear end of the installation device. The bent tempered glass body includes a first tempered glass and a second tempered glass, with an adhesive layer installed between the first and second tempered glass. Side adhesive layers are installed at the left and right ends of both the first and second tempered glass. The protective device includes a second Low-E film. A third Low-E film is fixedly installed at the front end of the second Low-E film. A first Low-E film is fixedly installed at the front end of the third Low-E film. The second Low-E film is fixedly installed at the front end of the first tempered glass. The installation device includes a first mounting bracket and a second mounting bracket, each with several screw holes at its front end.

[0007] In one embodiment, the first mounting bracket is fixedly installed on the upper end of the curved tempered glass body, and the second mounting bracket is fixedly installed on the lower end of the curved tempered glass body.

[0008] The tempered glass body is composed of tempered glass No. 1 and tempered glass No. 2. The double-layer structure greatly increases the impact resistance. Even if one layer breaks, the other layer can still maintain the support, reducing the risk of overall breakage. Moreover, even if it breaks, it breaks into blunt-angled honeycomb-shaped particles, avoiding sharp fragments from flying and injuring people, thus improving safety.

[0009] In one embodiment, the support device includes a support base, with two mounting screws installed at both the upper and lower front ends of the support base. Several support blocks are fixedly installed at the front end of the support base, and the support base is fixedly installed at the rear ends of the first and second mounting frames by the mounting screws.

[0010] The support base is fixed to the No. 1 and No. 2 mounting brackets by the mounting screws on it. At this time, several support blocks on the support base fit exactly against the curved part of the curved tempered glass body, thereby providing further support to the curved tempered glass body and preventing the curved tempered glass body from easily breaking under stress.

[0011] In one embodiment, the adhesive layer is an SGP film, and the side adhesive layer is a silicone sealant.

[0012] SGP film is a type of semi-transparent film made from a mixture of polyethylene terephthalate and metal salt ions. It bonds with glass and metals through ionic bonds, exhibiting excellent adhesion properties. The bonding strength with glass materials is above 20 MPa. At the same thickness, the load-bearing capacity of SGP interlayer is twice that of PVB. When laminated glass produced with SGP ionic interlayer film is under stress, there is virtually no slippage between the two glass panes. Under the same load and thickness, the bending deflection of SGP laminated glass is one-quarter that of PVB. At the same thickness, the tear strength of SGP interlayer film is five times that of PVB. Even when torn, it can still bond to the glass. At the same time, SGP interlayer film is colorless and transparent, UV resistant, and does not easily yellow after long-term exposure to sun and rain, further improving the performance and strength of the bent tempered glass body.

[0013] In one embodiment, the second Low-E film, the third Low-E film, and the first Low-E film are bonded together with a polyurethane adhesive.

[0014] Low-E film is a special coating material with high reflectivity and low emissivity. It achieves high transmittance of visible light and effective reflection of infrared rays by coating one or more layers of metal or metal oxide film on the glass surface, thus playing a role in heat insulation. Furthermore, the three-layer film design gives the curved tempered glass body higher heat insulation performance and lower emissivity.

[0015] In one embodiment, both the first mounting bracket and the second mounting bracket are T-shaped.

[0016] In one embodiment, the front end face of the support block is arc-shaped, and the support block abuts against the rear end of the curved tempered glass body.

[0017] The aforementioned high-temperature resistant tempered glass is composed of two tempered glass layers, a double-layer structure that significantly enhances its impact resistance. Even if one layer breaks, the other layer maintains its support, reducing the risk of overall breakage. Furthermore, even if it breaks, the fragments shatter into blunt-angled honeycomb-like particles, preventing sharp shards from flying and causing injury, thus improving safety. The two tempered glass layers are bonded together by an adhesive layer, SGP film, a semi-transparent film made from a mixture of polyethylene terephthalate and metal salt ions. This film bonds with glass and metals via ionic bonds, exhibiting excellent adhesion properties and a bonding strength exceeding 20 MPa. At the same thickness, the load-bearing capacity of the SGP interlayer is twice that of PVB. When subjected to stress, the two panes of glass in laminated glass using SGP ionic interlayer film show virtually no slippage. Under the same load and thickness, the bending deflection of SGP laminated glass is one-quarter that of PVB. At the same thickness, SGP... The tear strength of the laminated film is 5 times that of PVB, and it can still bond to the glass even when torn. The SGP laminated film is colorless and transparent, UV resistant, and does not easily yellow after long-term exposure to sun and rain, further improving the performance and strength of the curved tempered glass body. In addition, both ends of the curved tempered glass body are equipped with side adhesive layers made of silicone, which effectively resists high and low temperatures. It does not easily become brittle at temperatures as low as -50 or -60 degrees Celsius, nor does it easily melt at temperatures as high as 200 or 300 degrees Celsius. It has good flexibility, and the silicone adhesive has good elasticity, adapting to the expansion and contraction of materials under different environmental conditions, maintaining a sealing and bonding effect, and is not easily broken or detached due to slight material movement. Therefore, it can resist the erosion of ultraviolet rays, rain, high and low temperatures for a long time, maintaining its stable performance. Furthermore, the outer side of the curved tempered glass body is equipped with a protective device, which is made of No. 1 Low- The curved tempered glass is composed of three layers: Low-E film, Low-E film 2, and Low-E film 3. Low-E film is a special coating material with high reflectivity and low emissivity. It achieves high transmittance of visible light and effective reflection of infrared rays by coating one or more layers of metal or metal oxide film on the glass surface, thus playing a role in heat insulation. The three-layer film design gives the curved tempered glass body higher heat insulation performance and lower emissivity. When the curved tempered glass body is transported, it is fixed to the No. 1 and No. 2 mounting brackets by mounting screws on the support base of the support device. At this time, several support blocks on the support base fit exactly against the curved part of the curved tempered glass body, thereby further supporting the curved tempered glass body and preventing the curved tempered glass body from being easily broken under stress.

It bonds with glass and metals through ionic bonds, exhibiting excellent adhesion performance. The bonding strength with glass materials is above 20 MPa.
