Description

Technical Field

[0001] This utility model relates to the field of composite heat-insulating and fire-resistant glass technology, specifically a composite heat-insulating and fire-resistant glass. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals as the main raw materials, with the addition of small amounts of auxiliary materials. Its main components are silicon dioxide and other oxides. Ordinary glass is mainly composed of silicate complex salts, an amorphous solid with an irregular structure. It is widely used in buildings for wind insulation and light transmission, and is a mixture. Among the many heat-resistant glass fiber products, those coated with heat-resistant coatings have seen continuous development. Compared to uncoated products, glass fiber products coated with heat-resistant inorganic materials have significantly improved heat resistance and superior properties such as high temperature resistance, fire resistance, and flame retardancy. Vermiculite-coated glass fiber products, as a type of heat-resistant coated product, have experienced rapid development in the past 20 years. This type of coated glass fiber product has excellent heat insulation and flame retardant properties. Compared to high-temperature resistant fiber products such as ceramic fiber products and high-silica glass fiber products, this coated product has a relatively simple manufacturing process and is inexpensive, thus attracting much attention and its application areas are expanding.

[0003] Existing composite fire-resistant glass typically uses only single-pane or wired glass with an insulating film on the outer surface to achieve fire resistance. However, its fire resistance is poor. In actual use, when wired glass cracks due to heat, smoke and dust can easily pass through the cracks, still affecting the other side of the glass. Furthermore, existing fire-resistant glass often cannot achieve a perfect seal with the window frame during installation. Although sealant can be used to fill the gaps, in practice, the sealant deforms along with the wired glass when it cracks, widening the gap between the glass and the window frame. Additionally, the sealant expands or chars when heated, worsening the seal between the glass and the window frame. Therefore, existing composite fire-resistant glass suffers from poor fire resistance and poor sealing with the window frame. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a composite heat-insulating and fire-resistant glass, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A composite heat-insulating and fire-resistant glass includes a first wired glass, the outer surface of which is provided with a first fire-resistant coating. A fire-resistant adhesive interlayer is bonded to the back of the first wired glass. A high-strength monolithic cesium potassium fire-resistant glass is bonded to the back of the fire-resistant adhesive interlayer. A second wired glass is bonded to the back of the high-strength monolithic cesium potassium fire-resistant glass. A vacuum cavity is formed between the front of the second wired glass and the back of the high-strength monolithic cesium potassium fire-resistant glass. An aerogel layer is bonded to the front of the second wired glass inside the vacuum cavity. A reinforcing frame is fixedly connected to the back of the first wired glass. A pressure cavity is formed on the inner sidewall of the reinforcing frame. A valve is fixedly connected to the lower surface of the reinforcing frame. A piston is slidably connected to the inner sidewall of the valve. A push rod is fixedly connected to the front of the piston. A spray pipe is fixedly connected to the outer surface of the reinforcing frame. A nozzle is formed on the outer surface of the spray pipe.

[0007] Optionally, the first fireproof coating is made of metal oxide, aluminum, or silver, and a second fireproof coating is bonded to the front of the high-strength monolithic cesium potassium fireproof glass. The second fireproof coating is made of metal oxide, aluminum, or silver.

[0008] Optionally, the inner wall of the first wired glass is provided with a first metal wire, and the middle part of the second wired glass is provided with a second metal wire.

[0009] Optionally, the inner wall of the pressure chamber is filled with ultrafine dry powder extinguishing agent, and the inner bottom wall of the pressure chamber is in communication with the interior of the valve.

[0010] Optionally, a spring is fixedly connected to the rear of the piston, and one end of the spring is fixedly connected to the inner wall of the valve.

[0011] Optionally, the front end of the push rod penetrates the outer surface of the valve and abuts against the back of the first wired glass, and a limit pin is inserted into the inner wall of the push rod, with one end of the limit pin inserted into the inner wall of the lower surface of the reinforcing frame.

[0012] Optionally, the two ends of the spray pipe are respectively connected to the outer surface of the valve, and the nozzles are provided in a plurality of them and are evenly distributed in a rectangular array.

[0013] This utility model provides a composite heat-insulating and fire-resistant glass, which has the following beneficial effects:

[0014] 1. This composite heat-insulating and fire-resistant glass, through the arrangement of a first wired glass, a first fire-resistant coating, a fire-resistant adhesive interlayer, a high-strength monolithic cesium potassium fire-resistant glass, a second wired glass, a vacuum cavity, and an aerogel layer, enables the composite heat-insulating and fire-resistant glass to have the effect of easily improving fire and heat insulation performance. Through the coordinated arrangement of the first wired glass, the first fire-resistant coating, the fire-resistant adhesive interlayer, the high-strength monolithic cesium potassium fire-resistant glass, the second wired glass, the vacuum cavity, and the aerogel layer, the heat-insulating and fire-resistant glass can have a multi-layer fire-resistant structure during use. Even if the outer structure breaks, the inner structure can continue to produce a fire-insulating effect, thereby achieving the purpose of easily improving fire and heat insulation performance.

[0015] 2. This composite heat-insulating and fire-resistant glass, through the reinforcement of the frame, pressure chamber, ultra-fine dry powder extinguishing agent, valve, push rod, and spray pipe, enables the composite heat-insulating and fire-resistant glass to facilitate further sealing of the window frame. By coordinating the reinforcement of the frame, pressure chamber, ultra-fine dry powder extinguishing agent, valve, push rod, and spray pipe, during use, if the first layer of wire-reinforced glass breaks, the extension of the push rod opens the valve, releasing the ultra-fine dry powder extinguishing agent from the nozzle on the outer surface of the spray pipe. This serves two purposes: firstly, it fills the gap between the glass and the window frame, increasing sealing performance and improving fire and heat insulation; secondly, the sprayed ultra-fine dry powder extinguishing agent extinguishes fire sources near the glass, thus achieving the purpose of facilitating further sealing of the window frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0022] This utility model provides a technical solution: a composite heat-insulating and fireproof glass, including a first wired glass 1, a first fireproof coating 2 on the outer surface of the first wired glass 1, the material of the first fireproof coating 2 being metal oxide, aluminum or silver, a second fireproof coating 6 bonded to the front of a high-strength monolithic cesium potassium fireproof glass 5, the material of the second fireproof coating 6 being metal oxide, aluminum or silver, a first metal wire 3 on the inner sidewall of the first wired glass 1, a second metal wire 8 in the middle of the second wired glass 7, a fireproof adhesive interlayer 4 bonded to the back of the first wired glass 1, a high-strength monolithic cesium potassium fireproof glass 5 bonded to the back of the fireproof adhesive interlayer 4, a second wired glass 7 bonded to the back of the high-strength monolithic cesium potassium fireproof glass 5, a vacuum cavity 9 between the front of the second wired glass 7 and the back of the high-strength monolithic cesium potassium fireproof glass 5, and an aerogel layer 10 bonded to the front of the second wired glass 7 inside the vacuum cavity 9.

[0023] To facilitate improved fire resistance and heat insulation performance, as shown in the attached diagram, this application adopts the following structure: a first wired glass 1, a first fire-resistant coating 2, a fire-resistant adhesive interlayer 4, a high-strength monolithic cesium potassium fire-resistant glass 5, a second wired glass 7, a vacuum cavity 9, and an aerogel layer 10 are arranged to enhance the fire resistance and heat insulation performance of the composite fire-resistant glass. In actual use, the first fire-resistant coating 2 and the second fire-resistant coating 6 can reflect infrared rays, thereby reducing heat absorption. If the first wired glass 1 cannot withstand the high temperature and shatters, the internal first metal wire 3 can keep the first fire-resistant coating 2 in a fixed state, thus isolating the fire. At this time, the fire-resistant adhesive interlayer 4 successively foams and expands, passing through the gaps in the broken first wired glass 1 to form a hard, milky-white foamed fire-resistant adhesive board, effectively blocking flames and isolating high temperatures and harmful substances. The high-strength monolithic cesium potassium fireproof glass 5 can remain unshaken for more than 90 minutes under the impact of flames up to 1000℃, thus buying precious time for people to escape and for disaster relief. The second wired glass 7 on the rear side plays the same role as the first wired glass 1. The vacuum cavity 9 and the aerogel layer 10 can effectively slow down the coarse heat transfer when the high-strength monolithic cesium potassium fireproof glass 5 is heated. That is, through the combined arrangement of the first wired glass 1, the first fireproof coating 2, the fireproof adhesive interlayer 4, the high-strength monolithic cesium potassium fireproof glass 5, the second wired glass 7, the vacuum cavity 9 and the aerogel layer 10, the heat-insulating fireproof glass can have a multi-layer fireproof structure during use. Even if the outer structure breaks, the inner structure can continue to produce fireproof and heat-insulating effects, thereby achieving the purpose of improving fireproof and heat-insulating performance. Example 2

[0024] This utility model provides the following technical solution: A reinforcing frame 11 is fixedly connected to the back of the first wire-reinforced glass 1. A pressure chamber 12 is formed on the inner wall of the reinforcing frame 11. The inner wall of the pressure chamber 12 is filled with ultrafine dry powder fire extinguishing agent 13. The inner bottom wall of the pressure chamber 12 is in communication with the interior of the valve 14. The valve 14 is fixedly connected to the lower surface of the reinforcing frame 11. A piston 15 is slidably connected to the inner wall of the valve 14. A spring 16 is fixedly connected to the back of the piston 15. One end of the spring 16 is fixedly connected to the inner wall of the valve 14. A push rod 17 is fixedly connected to the front of valve 14. The front end of the push rod 17 passes through the outer surface of valve 14 and abuts against the back of the first wire-reinforced glass 1. A limit pin 18 is inserted into the inner wall of the push rod 17. One end of the limit pin 18 is inserted into the inner wall of the lower surface of the reinforcing frame 11. A spray pipe 19 is fixedly connected to the outer surface of the reinforcing frame 11. Both ends of the spray pipe 19 pass through the outer surface of valve 14. Several nozzles 20 are provided and are evenly distributed in a rectangular array. The outer surface of the spray pipe 19 is provided with nozzles 20.

[0025] To facilitate further sealing of the window frame, as shown in the attached document... Figure 1 After Figure 4 As shown, this application adopts the following structure. By strengthening the frame 11, pressure chamber 12, ultrafine dry powder extinguishing agent 13, valve 14, push rod 17, and spray pipe 19, the composite heat-insulating fireproof glass has the effect of facilitating further sealing of the window frame. In actual use, when the first wired glass 1 breaks, the lower side of the first wired glass 1 breaks and loses its shielding of the end of the push rod 17. At this time, the spring 16 pushes the piston 15 forward, causing the valve 14 to open. The ultrafine dry powder extinguishing agent 13 inside the pressure chamber 12 enters the spray pipe 19 from the valve 14 due to the high pressure, and is then sprayed from the nozzle 20 on the outer surface of the spray pipe 19 towards the connection between the glass and the window frame. The setting of the limiting pin 18 The push rod 17 can be limited during installation and transportation to prevent accidental spraying of the ultrafine dry powder extinguishing agent 13. It can fill the gaps at the joints, and the initially sprayed ultrafine dry powder extinguishing agent 13 can extinguish the fire source near the glass. That is, by strengthening the cooperation of the frame 11, pressure chamber 12, ultrafine dry powder extinguishing agent 13, valve 14, push rod 17 and spray pipe 19, during use, on the one hand, it can fill the gap between the glass and the window frame, increase the sealing performance, and improve the fireproof and heat insulation effect. On the other hand, the sprayed ultrafine dry powder extinguishing agent 13 can extinguish the fire source near the glass, thereby facilitating further sealing of the window frame.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
