Abstract
Description
Technical Field
[0001] This utility model relates to the field of building materials and safety protection technology, and in particular to a fireproof glass with built-in metal mesh reinforcement. Background Technology
[0002] In modern architecture and industry, fire-resistant glass is an important safety material widely used in building curtain walls, doors and windows, and fire-resistant partitions. Its primary function is to buy precious time for evacuation and property protection by blocking the spread of flames and high temperatures during a fire. However, traditional fire-resistant glass still has certain limitations in practical applications. For example, while single-layer or multi-layer composite fire-resistant glass possesses certain fire resistance properties, it is prone to cracking due to thermal stress concentration under high temperatures, thus losing its fire-resistant function. Furthermore, existing fire-resistant glass has relatively weak mechanical strength and impact resistance, making it easily damaged by external impacts or vibrations, further limiting its application in high-safety-requirement environments.
[0003] Currently, there are some technical solutions on the market that improve the performance of fire-resistant glass by incorporating metal mesh or other reinforcing materials. However, these solutions generally suffer from complex structures, high manufacturing costs, or limited reinforcement effects. Especially under high-temperature conditions, insufficient bonding strength between the metal mesh and the glass substrate may lead to delamination or detachment, affecting the overall stability and reliability of performance. Therefore, designing a solution that can significantly improve the fire resistance and mechanical strength of fire-resistant glass while ensuring a simple structure, economical manufacturing, and stable performance has become an urgent technical challenge. Utility Model Content
[0004] The purpose of this utility model is to provide a fireproof glass with built-in metal mesh reinforcement, which solves the problems mentioned in the background art.
[0005] This invention is implemented as follows: a fireproof glass reinforced with an embedded metal mesh includes an outer glass panel and an inner glass panel, and further includes a composite heat insulation layer located between the outer and inner glass panels. The composite heat insulation layer is composed of multiple layers of transparent heat insulation films. A metal mesh is embedded in the center of the composite heat insulation layer, and the metal mesh is fixed between the heat insulation films on both sides of the composite heat insulation layer through multiple evenly distributed connection points. The metal mesh is made of a specially treated high-temperature resistant alloy material, and its mesh shape is a hexagonal honeycomb structure. The outer glass panel and the inner glass panel are sealed by an edge sealing strip, and the sealing strip is filled with flame-retardant colloid.

[0006] Preferably, a buffer layer is provided on both sides of the composite heat insulation layer.

[0012] This invention provides a fire-resistant glass reinforced with an embedded metal mesh. The advantages are as follows: By embedding a hexagonal honeycomb metal mesh into the composite insulation layer, this invention significantly improves the overall strength of the fire-resistant glass and effectively disperses internal stress under high-temperature conditions, thus preventing the glass from cracking due to thermal stress concentration.

Detailed Implementation
[0018] This utility model provides a fire-resistant glass reinforced with an embedded metal mesh. Its structural design and material selection have been carefully optimized to solve the problems of insufficient strength, limited heat insulation performance, and high production costs of existing fire-resistant glass. The following is in conjunction with the appendix... Figure 1 To be continued Figure 3 The specific embodiments of this utility model will be described in detail.
[0019] like Figure 1-2 As shown, the overall structure of the fireproof glass with built-in metal mesh reinforcement of this utility model includes an outer glass plate 1, an inner glass plate 2, a composite heat insulation layer 3, a first vacuum chamber 5, a second vacuum chamber 6, an edge sealing strip 8, and other auxiliary structures. Both the outer glass plate 1 and the inner glass plate 2 are high-strength transparent glass, preferably 4mm to 6mm thick, capable of withstanding a certain amount of external impact. The composite heat insulation layer 3 is located between the outer glass plate 1 and the inner glass plate 2, and is composed of multiple layers of transparent heat insulation film, each layer being 0.1mm to 0.2mm thick, and preferably 5 to 8 layers. A metal mesh 4 is embedded in the center of the composite heat insulation layer 3, and the metal mesh 4 is fixed between the heat insulation films on both sides of the composite heat insulation layer 3 through multiple evenly distributed connection points, such as... Figure 2 As shown. This hexagonal honeycomb structure of the metal mesh 4 not only has excellent mechanical properties, but also effectively disperses internal stress under high-temperature conditions, thereby avoiding glass breakage caused by thermal stress concentration.
[0020] The metal mesh 4 is made of specially treated high-temperature resistant alloy materials, such as nickel-based alloys or titanium-based alloys, which maintain good mechanical strength and oxidation resistance at high temperatures. To further enhance the durability of the metal mesh 4, its surface is coated with an anti-oxidation coating 11, which is made of a mixture of graphene and epoxy resin and has a thickness of 10 μm to 20 μm. The anti-oxidation coating 11 not only effectively prevents oxidation and corrosion of the metal mesh 4 in long-term high-temperature environments, but also enhances its adhesion to the composite insulation layer 3.
[0021] A first vacuum cavity 5 is provided between the outer glass plate 1 and the composite heat insulation layer 3, and a second vacuum cavity 6 is provided between the inner glass plate 2 and the composite heat insulation layer 3. Figure 1 As shown, both the first vacuum chamber 5 and the second vacuum chamber 6 are 2mm to 3mm thick and filled with inert gases, such as argon or krypton. This double-vacuum-chamber design significantly improves the thermal insulation performance of the fire-resistant glass, making it difficult for heat to be transferred to the inner glass panel 2 via conduction and convection, thus maintaining good thermal insulation even under extreme conditions such as fires. Furthermore, the presence of the first vacuum chamber 5 and the second vacuum chamber 6 effectively reduces the intrusion of external noise, improving the sound insulation performance of the fire-resistant glass.
[0022] Buffer layers 7 are provided on both sides of the composite heat insulation layer 3. The buffer layers 7 are made of elastic polymer materials, such as silicone or polyurethane, with a thickness of 0.5 mm to 1 mm. The surface of the buffer layers 7 has a microporous structure. This microporous structure enhances the adhesion between the buffer layers 7 and the composite heat insulation layer 3, and also acts as a buffer against external impacts, thus protecting the composite heat insulation layer 3 from damage. The presence of the buffer layers 7 also mitigates the thermal expansion and contraction effect caused by temperature changes, further improving the overall stability of the fireproof glass.
[0023] Edge sealing strip 8 is used to seal the outer glass plate 1 and the inner glass plate 2, and its inner side is filled with flame-retardant adhesive 9, such as... Figure 3 As shown. The flame-retardant colloid 9 is preferably a silicone-based flame-retardant material, which can maintain stable physical and chemical properties at high temperatures and prevent flames from penetrating the interior of the fireproof glass from the edge. In addition, multiple spaced support columns 13 are provided on the inner side of the edge sealing strip 8. The height of the support columns 13 is the same as the thickness of the composite heat insulation layer 3, which is used to maintain the distance between the outer glass plate 1 and the inner glass plate 2, ensuring that the thickness of the first vacuum chamber 5 and the second vacuum chamber 6 remains consistent.
[0024] The outer surface of the outer glass panel 1 is coated with an explosion-proof coating 10, which is made of a mixture of nano-sized ceramic particles and silicone resin, with a thickness of 0.1 mm to 0.2 mm. The explosion-proof coating 10 can absorb some energy when the glass is impacted, reducing the risk of glass breakage and improving the scratch resistance of the fire-resistant glass. To further enhance the self-cleaning ability of the fire-resistant glass, a self-cleaning layer 14 is also provided on the outer surface of the explosion-proof coating 10. The self-cleaning layer 14 is made of titanium dioxide photocatalytic material, with a thickness of 5 μm to 10 μm. The self-cleaning layer 14 can decompose organic pollutants adhering to the glass surface under sunlight, maintaining the cleanliness of the glass.
[0025] Each grid node of the metal mesh 4 is equipped with a miniature thermal element 12, which is connected to an external alarm system via wires. When the ambient temperature exceeds a preset value, the miniature thermal element 12 will trigger an alarm signal, alerting relevant personnel to take emergency measures. This intelligent design enables the fireproof glass to not only provide passive protection but also actively monitor changes in the surrounding environment, providing strong support for building safety management.
[0026] In practical applications, the fire-resistant glass with built-in metal mesh reinforcement of this invention can be widely used in high-rise buildings, subway stations, airports, and other places requiring high fire resistance. For example, in the curtain wall system of high-rise buildings, fire-resistant glass can be used as an exterior wall material; its high strength and high heat insulation performance can effectively delay the spread of fire, buying valuable time for evacuation. In public places such as subway stations and airports, fire-resistant glass can be used as partition walls or safety doors, meeting fire protection requirements while providing good visual transparency.
[0027] In summary, this invention significantly improves the overall performance of fire-resistant glass through innovative structural design and material selection. The combination of the hexagonal honeycomb metal mesh 4 and the composite insulation layer 3 not only enhances the strength of the fire-resistant glass but also effectively disperses internal stress under high-temperature environments. The dual-vacuum-cavity design greatly improves thermal insulation performance, while the introduction of the explosion-proof coating 10 and the self-cleaning layer 14 further enhances the practicality and aesthetics of the fire-resistant glass. Furthermore, the intelligent design of the micro-thermal element 12 enables the fire-resistant glass to possess active monitoring capabilities, providing a new solution for building safety management.
