Description

Technical Field

[0001] This utility model relates to the field of building materials and glass, and in particular to a grouted composite fireproof glass. Background Technology

[0002] Existing fire-resistant glass suffers from insufficient heat insulation, poor structural stability, and excessive weight. While monolithic fire-resistant glass is easy to install, its fire resistance time is short; insulated fire-resistant glass offers better heat insulation, but its sealing performance is prone to failure. Grouted composite fire-resistant glass combines the advantages of both, improving heat insulation and fire resistance by injecting fire-resistant grout into the glass interlayer. However, existing products still suffer from defects such as poor grout flowability, uneven curing, and weak bonding between the grout and the glass interface, resulting in unstable fire resistance, easy cracking, and high maintenance costs. Therefore, an improved grouted composite fire-resistant glass structure and manufacturing method are needed.

[0003] Chinese Patent Publication No. CN217373740U discloses a utility model of grouted composite fireproof glass, belonging to the field of grouted fireproof glass technology. The utility model includes two inner glass layers with a sealing ring between them. An outer glass layer is connected to the outer side of each inner glass layer. A fireproof liquid layer is disposed between the two inner glass layers inside the sealing ring. A first composite layer is installed between the inner and outer glass layers. A second composite layer is connected to the side of the outer glass layer away from the first composite layer. The first composite layer includes a buffer layer, and elastic layers are fixed to both sides of the buffer layer. This utility model, through the combination of the elastic layer and the buffer layer, can greatly enhance the compressive strength of the device. Simultaneously, through the combination of the ceramic fiber layer and the carbon fiber layer, it can enhance the structural strength of the device, thereby greatly improving the impact resistance of the device and effectively preventing breakage and explosion, resulting in excellent performance.

[0004] Currently, traditional grouted composite fireproof glass on the market has significant shortcomings in practical applications. Its shock absorption performance is weak; when faced with minor external vibrations, impacts, or slight deformations of the building structure, it is prone to stress damage due to insufficient impact resistance, affecting both aesthetic integrity and potential structural stability. Its sealing design is relatively simple, relying heavily on a basic sealant layer, which is susceptible to sealing failure after long-term use due to temperature and humidity changes and aging, leading to moisture penetration or loss of the fireproof grout. Furthermore, its fireproof performance is limited, mostly meeting only basic fireproofing or heat insulation requirements, making it difficult to cope with complex fire scenarios. In high-temperature environments, core fireproof components are prone to performance degradation or even failure, unable to provide sustained protection. Moreover, limited by its structural and material characteristics, its adaptability to different scenarios is poor, making it difficult to flexibly match different building types and installation requirements, thus restricting its application scope.

[0005] Therefore, we propose a grouting composite fireproof glass to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a grouted composite fireproof glass that solves the problems of weak shock absorption, simple sealing, single fireproof performance, easy failure at high temperatures, and poor adaptability to various scenarios in the existing traditional fireproof glass.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A grouted composite fireproof glass includes an outer shell.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Reference Figure 1-5A type of grouted composite fireproof glass includes an outer shell 1. Shock-absorbing pads 2 are fixedly connected to the inner surfaces of the four corners of the outer shell 1, effectively buffering external vibrations and impacts on the glass, preventing breakage or structural loosening due to vibration, and improving the structural stability of the glass during transportation, installation, and use. Simultaneously, a sealing gasket 3 fixedly connected to one side of the shock-absorbing pads 2 provides a good seal for the first substrate 5, fireproof interlayer 6, second substrate 7, and third substrate 8, preventing external moisture, dust, and other impurities from entering the glass interior, thus avoiding internal structural dampness and contamination that could affect fire resistance and service life. Furthermore, the fireproof interlayer 6 fixedly connected to one side of the first substrate 5 plays a crucial role in blocking flames and high temperatures during a fire, while the filling cavity 9 between the second substrate 7 and the third substrate 8 improves the glass's heat insulation, impact resistance, or sound insulation performance, giving the fireproof glass excellent comprehensive performance in fire resistance, shock absorption, and sealing, meeting the needs of various application scenarios.

[0021] Furthermore, in this grouted composite fireproof glass, the sealing gasket 3 can be selected from any one of ceramicized silicone rubber, silicone rubber, and glass fiber composite gaskets, which can optimize the overall performance from multiple dimensions: When ceramicized silicone rubber is selected, it can tightly adhere to the outer shell 1, the first substrate 5, the second substrate 7, and the third substrate 8 at room temperature to form a stable seal, preventing moisture and dust from entering the filling cavity 9 and the fireproof interlayer 6. At high temperatures, it can also be transformed into an inorganic ceramic-like substance that is non-combustible and produces no toxic fumes, forming a double fireproof barrier with the fireproof interlayer 6; when silicone rubber is selected, it has excellent aging resistance and weather resistance, and is not prone to cracking and hardening in harsh environments over a long period of time. It can provide a durable seal and buffer minor vibrations to avoid seal failure; when glass fiber composite gaskets are used, they can withstand assembly extrusion pressure with high strength and are not easily deformed. At the same time, they can resist fire baking with their high-temperature resistance, which helps to enhance the connection stability of each structural layer and comprehensively improve the sealing reliability, fire safety, and service life of the glass.

[0022] Furthermore, the material of the first substrate 5 can be either thermally tempered glass or chemically tempered glass. Thermally tempered glass undergoes high-temperature treatment and rapid cooling, resulting in compressive stress on the surface and tensile stress inside, making its impact resistance much higher than that of ordinary glass. It can effectively resist external impacts and reduce the probability of glass breakage. Chemically tempered glass, on the other hand, alters the chemical composition of the glass surface through an ion exchange process, also possessing high strength and toughness. Compared to thermally tempered glass, it has better flatness and smaller thickness deviation, allowing for better adhesion to other structural layers and ensuring the stability of the overall glass structure. As one of the outer layers of the glass, the high-strength first substrate 5 provides excellent protection for internal structures such as the fireproof interlayer 6, preventing damage to the internal structure when subjected to external impacts. It also improves the overall wind pressure resistance and bending resistance of the glass, extending its service life.

[0023] Furthermore, the fire-resistant interlayer 6 can be made of any one of the following materials: hydrogel, silicate gel, or polymer. All materials offer excellent fire resistance. Hydrogel materials contain a large amount of water, which evaporates under high temperatures, absorbing a significant amount of heat and lowering the glass surface temperature. Simultaneously, they form a water vapor barrier, blocking oxygen and flame propagation. Silicate gel materials possess excellent high-temperature stability, are not easily combustible in a fire, do not produce toxic or harmful gases, and can form a dense heat-insulating layer, effectively blocking high-temperature transmission and protecting the safety of people and property on the other side of the glass. Polymer materials have good adhesion and formability, allowing them to bond tightly with the first substrate 5 and the second substrate 7 to form a complete fire-resistant structure. Under high temperatures, they can expand to form a carbonized layer, further blocking flames and high temperatures. Different types of fire-resistant interlayer materials can be selected according to specific fire resistance requirements and application scenarios, ensuring that the grouted composite fire-resistant glass consistently performs its fire-resistant performance under various fire conditions, providing users with reliable safety assurance.

[0024] Furthermore, the material of the second substrate 7 is either tin-zinc oxide sheet or doped tin-zinc oxide sheet. Tin-zinc oxide sheet maintains stable structure and performance under high-temperature conditions, is not easily deformed or melted, and can serve as an important structural support layer in a fire to prevent the overall glass structure from collapsing due to high temperatures. It also possesses certain thermal insulation properties, helping to block high-temperature transmission. Doped tin-zinc oxide sheet, on the other hand, effectively improves high-temperature resistance, mechanical strength, and chemical stability by doping other elements into tin-zinc oxide, and may even possess certain electrical conductivity. This allows for the expansion of glass functions according to actual needs, such as for applications requiring anti-static properties or specific electrical requirements. The superior performance of the second substrate 7 not only enhances the overall high-temperature resistance and structural stability of the glass but also provides possibilities for expanding glass functions, thereby improving product competitiveness.

[0025] Furthermore, the third substrate 8 can be made of either borosilicate glass or polycarbonate resin sheet. The two materials complement each other, meeting diverse application requirements. Borosilicate glass has an extremely low coefficient of thermal expansion, excellent high-temperature resistance, and is not easily broken under rapid temperature changes, allowing it to withstand temperature fluctuations in high-temperature environments such as fires. Its high transparency ensures good light transmission. Polycarbonate resin sheet, on the other hand, has excellent impact resistance and toughness, is not easily broken even under strong impacts, and is lightweight, facilitating transportation and installation. It also possesses certain high-temperature resistance and fire resistance. As one of the outer layers of the glass, the third substrate 8 utilizes borosilicate glass to ensure structural stability and light transmission at high temperatures, while the polycarbonate resin sheet enhances impact resistance and ease of use. The choice of different materials allows the grouted composite fireproof glass to be applied to various scenarios such as building curtain walls, fireproof doors and windows, and partitions, meeting diverse user needs for glass performance.

[0026] Specifically, the material of the shock-absorbing pad 2 can be any one of silicone rubber, glass fiber and silicone rubber composite material, or fireproof glass gasket, each with its own advantages. Silicone rubber has good elasticity and aging resistance, maintaining excellent shock absorption for a long time, and its performance is stable within a certain temperature range, adapting to different environmental temperature changes. Glass fiber and silicone rubber composite material combines the high strength of glass fiber and the elasticity of silicone rubber, not only providing significant shock absorption but also improving the structural strength and high-temperature resistance of the shock-absorbing pad 2, preventing rapid damage and loss of shock absorption function under high-temperature environments. Fireproof glass gasket itself has good fire resistance; in the event of a fire, in addition to its shock absorption function, it can also help block the spread of flames, further improving the fire resistance reliability of the entire grouted composite fireproof glass. The choice of multiple materials can meet the specific performance requirements of the shock-absorbing pad 2 in different application scenarios, enhancing the applicability and flexibility of the product.

[0027] In summary: In the grouted composite fireproof glass, the outer shell 1 is located on the outermost layer, providing support and protection for the internal components. It integrates the components through its own structural strength to maintain overall stability. The shock-absorbing pad 2 is connected between the inner surface of the outer shell 1 and the sealing gasket 3 and the substrate. It absorbs vibrations through the elasticity of the material and can also assist in fire prevention. The sealing gasket 3 is between the shock-absorbing pad 2 and the internal functional layer, surrounding the core structure. It blocks external impurities through the sealing properties of the material and keeps the components tightly connected. The first substrate 5 is between the shock-absorbing pad 2 and the fireproof interlayer 6. It resists external forces with its high strength characteristics and protects the fireproof interlayer 6. The fireproof interlayer 6, as the core fireproof layer, is sandwiched between the two substrates and blocks flames and high temperatures based on its material properties. The second substrate 7 is located between the fireproof interlayer 6 and the third substrate 8. It provides support and enhances high-temperature resistance. It can also expand functions. The third substrate 8 and the second substrate 7 form a filling cavity 9, which has both protective and performance optimization functions. The filling cavity 9 can be filled with materials to improve additional performance and can also relieve substrate deformation stress. All components work together to ensure the overall performance of the glass.
