Description

Technical Field

[0001] This utility model relates to the field of building materials and fireproofing and heat insulation technology, and in particular to a surface-coated fire-resistant and heat-insulating glass device. Background Technology

[0002] In modern architecture and industry, glass, as an important building material, is widely used in windows, curtain walls, partitions, and other applications. With increasing demands for building safety and energy efficiency, fire-resistant and heat-insulating glass devices have gradually become a research and application hotspot. Traditional glass materials are prone to cracking at high temperatures and have limited heat insulation performance, making it difficult to meet the dual requirements of fire prevention and energy conservation. To address this issue, existing technologies typically employ laminated glass or coated glass to improve fire resistance and heat insulation performance. However, these technologies still have certain shortcomings. For example, while laminated glass has some fire resistance, its heat insulation effect is limited, and its weight increases the difficulty of installation and use; while coated glass can improve heat insulation performance, the coating is prone to peeling off under high temperatures, resulting in poor fire resistance stability. Furthermore, existing fire-resistant and heat-insulating glass devices often experience performance degradation and reduced service life due to insufficient adhesion or poor weather resistance of the surface coating during long-term use. Therefore, developing a glass device that can effectively improve fire resistance and heat insulation performance while possessing excellent surface coating stability has become a pressing technical challenge. This utility model aims to overcome the shortcomings of existing technologies through innovative design and provide a high-efficiency and reliable surface-coated fire-resistant and heat-insulating glass device.

[0019] This utility model provides a surface-coated fire-resistant and heat-insulating glass device. Its ingenious structural design and comprehensive functions effectively solve the problems of insufficient heat insulation performance, easy film peeling, and poor fire resistance in existing surface-coated glass under high-temperature environments. The following, in conjunction with the appendix... Figure 1 To be continued Figure 3 The specific embodiments of this utility model will be described in detail to clarify the implementation process and operating principle of its technical solution.

[0020] like Figure 1 The diagram shows the overall structure of this utility model. The device includes a substrate 1, a vacuum insulation cavity 2, support columns 3, a coating layer 4, a fire-resistant coating 5, a heat-conducting strip 6, a heat sink 7, a reinforcing frame 8, elastic gaskets 9, a mounting groove 10, and a sealing strip 15, among other main components. The substrate 1 adopts a double-layer structure design, forming a vacuum insulation cavity 2 between the two substrate layers. This design significantly improves the heat insulation performance of the glass by blocking air convection and heat conduction. To ensure the stability of the vacuum insulation cavity 2 and prevent the two substrate layers from collapsing due to external pressure, multiple evenly distributed support columns 3 are provided within the vacuum insulation cavity 2. Figure 2 The partial cross-sectional view clearly shows that the support column 3 is made of ceramic material, and both ends of it are provided with spherical protrusions. These spherical protrusions are embedded in the inner surface of the substrate 1, thereby enhancing the stability of the connection and preventing the support column 3 from shifting or falling off during long-term use.

[0021] The coating layer 4 is fixed to the outer surface of the substrate 1 by an adhesive, and its function is to improve the glass's weather resistance, heat insulation, and UV protection. Figure 3As can be seen, the coating layer 4 is a multi-layered composite structure, consisting of a weather-resistant layer 11, a heat-insulating layer 12, and a UV-protective layer 13 stacked sequentially. The weather-resistant layer 11 is located on the outermost layer, directly in contact with the external environment, and possesses excellent anti-aging properties. The heat-insulating layer 12 is located in the middle layer, used to further reduce heat transfer. The UV-protective layer 13 is close to the outer surface of the substrate 1, serving to block ultraviolet rays, thereby protecting the substrate 1 from UV damage. This multi-layered composite structure design allows the coating layer 4 to not only possess the advantages of a single function but also achieve the synergistic effect of multiple functions, extending the service life of the glass.

[0022] To further improve the fire resistance of the glass, a fire-resistant coating 5 with a thickness of 0.1 mm to 0.3 mm is applied to the outer surface of the coating layer 4. The fire-resistant coating 5 contains nano-sized silica particles, which significantly enhance the coating's high-temperature resistance, allowing it to maintain good integrity even under extreme high-temperature environments and preventing damage to the glass surface due to high temperatures. Furthermore, the presence of the fire-resistant coating 5 effectively shields the glass from radiant heat, reducing the overall temperature of the glass and thus providing more reliable fire protection for the building.

[0023] A heat-conducting strip 6 is fixedly attached to the edge of the substrate 1. One end of the heat-conducting strip 6 extends into the interior of the substrate 1, and the other end is connected to the heat sink 7. The heat-conducting strip 6 is made of copper-aluminum alloy, and its surface is coated with an anti-oxidation coating to enhance corrosion resistance. Figure 2 As shown, the heat-conducting strip 6 has multiple heat-conducting holes 16, which are evenly distributed along the length of the heat-conducting strip 6 and filled with thermal grease to further improve heat conduction efficiency. The main function of the heat-conducting strip 6 is to quickly conduct the heat accumulated inside the substrate 1 due to the high external temperature and dissipate it to the surrounding environment through the heat sink 7. The heat sink 7 has a wave-shaped design, and its surface is provided with multiple heat dissipation holes 17 with a diameter of 2mm to 5mm. This design not only increases the heat dissipation area but also promotes airflow, thereby improving the heat dissipation effect.

[0024] To enhance the structural strength of the entire device, a reinforcing frame 8 is provided around the substrate 1 and fixedly connected to the substrate 1 with bolts. An elastic gasket 9 is provided on the inner side of the reinforcing frame 8, which is in close contact with the outer surface of the substrate 1 to buffer external impact and prevent damage to the substrate 1 due to vibration. In addition, a mounting groove 10 is provided on the outer side of the reinforcing frame 8. The mounting groove 10 is used for installation with other fixing structures, allowing users to flexibly adjust the position and angle of the glass device according to actual needs. A buffer layer 14 with a thickness of 0.2mm to 0.5mm is also provided between the substrate 1 and the coating layer 4. The buffer layer 14 is made of silicone, whose soft properties can absorb stress changes to a certain extent, preventing the coating layer 4 from cracking or peeling due to thermal expansion and contraction.

[0025] like Figure 1 As shown, the sealing strip 15 is disposed at the edge of the substrate 1 and contacts the inner side of the reinforcing frame 8. The sealing strip 15 is made of high-temperature resistant silicone rubber, and its main function is to ensure that the device maintains good airtightness in high-temperature environments, preventing external dust or moisture from entering the vacuum insulation cavity 2, thereby maintaining the heat insulation effect of the vacuum insulation cavity 2. At the same time, the sealing strip 15 also plays a certain role in sound insulation, further improving the overall performance of the glass device.

[0026] The working principle of this invention is as follows: When the glass device is exposed to a high-temperature environment, the vacuum insulation cavity 2 first significantly reduces the rate of heat transfer to the interior of the substrate 1 by blocking air convection and heat conduction. Simultaneously, the heat insulation layer 12 and the UV-resistant layer 13 in the coating layer 4 work together to further reduce heat absorption and transfer. If the external temperature continues to rise, the fire-resistant coating 5 activates its protective mechanism, using doped nano-sized silica particles to resist high-temperature erosion and ensure that the glass surface is not damaged by overheating. During this process, some heat may still accumulate inside the substrate 1. At this time, the heat-conducting strip 6 begins to work, quickly dissipating heat through the thermally conductive grease in the heat-conducting holes 16, and dissipating the heat into the air with the help of the wavy design of the heat sink 7 and the heat dissipation holes 17, thereby effectively reducing the overall temperature of the glass. Furthermore, the combined use of the reinforcing frame 8 and the sealing strip 15 ensures the stability and sealing of the device under high-temperature conditions, preventing performance degradation caused by external factors.

[0027] This invention is applicable to various architectural glass needs in high-temperature environments, such as windows in industrial plants, curtain walls of large shopping malls, and sunrooms in residential buildings. Taking industrial plants as an example, ordinary glass is insufficient to meet the requirements for heat insulation and fire resistance due to the large amount of heat generated by high-temperature equipment or production processes inside the plant. This invention, through the aforementioned design, not only effectively blocks heat transfer but also provides additional safety in emergencies such as fires, fully demonstrating its practicality and promotional value.

[0028] In summary, this utility model, through its scientific and rational structural design and material selection, successfully solves many problems existing in the prior art, achieving a high degree of integration of multiple functions such as heat insulation, fire resistance, and heat dissipation. Its compact structure and convenient installation method also provide great convenience for practical applications, making it a highly innovative and promising technical solution.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
