Description

Technical Field

[0001] This utility model relates to the field of edge scratch protection technology for doors and windows, specifically an edge scratch protection structure for aluminum alloy door and window glass. Background Technology

[0002] Aluminum alloy doors and windows are widely used in modern buildings due to their advantages such as light weight, high strength, and good corrosion resistance. However, the protection of the glass edges in aluminum alloy doors and windows has gradually become a prominent issue during use. During installation, cleaning, daily use, and contact with other objects, the glass edges are easily scratched and worn due to collisions and friction, which may even lead to glass breakage. This not only affects the aesthetics and lifespan of the doors and windows but also poses safety hazards.

[0003] Currently, common edge protection measures for aluminum alloy door and window glass on the market mainly focus on simple plastic or rubber edge protectors and sealing strips. While these methods offer some protection, they have several shortcomings. For example, plastic or rubber edge protectors are relatively hard, have limited cushioning performance, and are difficult to effectively absorb external impacts. Furthermore, they are prone to aging and deformation over long-term use, losing their protective function. Sealing strips, while providing some sealing and cushioning, primarily prevent air and moisture penetration, offering weak physical protection for the glass edges. They are also relatively complex to install and replace, and repair costs are high once damaged.

[0004] Therefore, a scratch-resistant protection structure for the edges of aluminum alloy door and window glass is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this paper addresses the current market's common edge protection measures for aluminum alloy door and window glass, which primarily rely on simple plastic or rubber edge protectors and sealing strips. While these methods offer some protection, they have several drawbacks. For example, plastic or rubber edge protectors are relatively hard, offering limited cushioning and failing to effectively absorb external impacts. Furthermore, they are prone to aging and deformation over long-term use, losing their protective function. Sealing strips, while providing some sealing and cushioning, primarily prevent air and moisture penetration, offering weak physical protection for the glass edges. They are also complex to install and replace, and repair costs are high if damaged.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The aluminum alloy door and window glass edge anti-scratch protection structure of this utility model includes an elastic protective sleeve, a buffer layer is fixedly connected to the inner side of the elastic protective sleeve, a wear-resistant layer is fixedly connected to the inner side of the buffer layer, a sealing layer is fixedly connected to the inner side of the wear-resistant layer, and the sealing layer is tightly attached to the glass edge surface.

[0007] Preferably, the elastic protective sleeve is made of highly elastic silicone, and the outer wall of the elastic protective sleeve is provided with anti-slip texture, the shape of which is rhomboid or circular.

[0008] Preferably, the buffer layer is made of polyurethane foam, and the thickness of the buffer layer is two to five millimeters, and the porosity of the buffer layer is thirty percent to fifty percent.

[0009] Preferably, the wear-resistant layer is made of rubber-modified epoxy resin, and the surface of the wear-resistant layer is coated with an anti-scratch coating with a thickness of 0.1 to 0.3 millimeters.

[0010] Preferably, the sealing layer is made of polytetrafluoroethylene, and the thickness of the sealing layer is 0.5 to 1 mm. The contact surface between the sealing layer and the glass edge is treated with nanoscale sealing technology.

[0011] Preferably, the elastic protective sleeve and the buffer layer are tightly bonded together with hot melt adhesive, and the elastic protective sleeve covers more than 90% of the outer area of ​​the buffer layer.

[0012] The advantages of this utility model are: This structure achieves comprehensive protection for the glass edges through the synergistic effect of multiple composite materials. The elastic protective sleeve is made of highly elastic silicone, possessing excellent elasticity and flexibility, effectively absorbing and buffering external impacts to prevent scratches or damage to the glass edges from collisions. The buffer layer is composed of polyurethane foam, with a thickness of two to five millimeters and a porosity of 30% to 50%. This porous structure further disperses and absorbs external forces, reducing the impact on the glass edges. The wear-resistant layer is made of rubber-modified epoxy resin, coated with a scratch-resistant coating 0.1 to 0.3 millimeters thick. This combination of material and coating not only resists friction and scratches from daily use but also effectively prevents the glass edges from being scratched by hard objects, maintaining the smoothness and integrity of the glass surface. The innermost sealing layer is made of polytetrafluoroethylene (PTFE) with a thickness of 0.5 to 1 millimeter. Its surface is treated with nano-level sealing technology, which allows it to fit tightly against the glass edge. This effectively prevents dust, moisture, and other contaminants from entering between the glass edge and the protective structure, avoiding corrosion and damage caused by long-term accumulation, thereby extending the service life of the glass. The outer wall of the elastic protective sleeve has anti-slip textures in the shape of diamonds or circles. This design not only increases the friction between the protective structure and the aluminum alloy door and window frame, preventing the protective structure from sliding or shifting during use, but also adapts to glass edges of different shapes and sizes, ensuring that the protective structure can be firmly fixed to the glass edge and will not loosen due to the opening and closing of doors and windows or external factors. Furthermore, the elastic protective sleeve and the buffer layer are tightly bonded together with hot melt adhesive, and the elastic protective sleeve covers more than 90% of the outer area of ​​the buffer layer. This tight connection gives the entire protective structure excellent integrity and stability, enabling it to better adapt to various complex usage environments and different installation conditions. Whether it's the high doors and windows of large public buildings or ordinary doors and windows in residential homes, it can effectively protect the glass edges from external factors. Aesthetically, the high-elasticity silicone material of the elastic protective sleeve has a good texture and gloss, blending seamlessly with the overall design style of aluminum alloy doors and windows without appearing abrupt or discordant. At the same time, the surface treatment of the wear-resistant layer and sealing layer ensures the smoothness and cleanliness of the entire protective structure, preventing wear or aging over long-term use and maintaining the beautiful appearance of the doors and windows. This aesthetic appeal not only enhances the overall quality of the building but also meets users' high demands for the aesthetics of doors and windows, allowing aluminum alloy doors and windows to become a highlight of the building's appearance while providing excellent protective performance.

[0016] Example 1 like Figure 1 The diagram shows an aluminum alloy door and window glass edge anti-scratch protection structure, including an elastic protective sleeve 1, a buffer layer 2, a wear-resistant layer 3, and a sealing layer 4.

[0017] Please see Figures 1 to 3 The diagram illustrates an aluminum alloy window glass edge anti-scratch protection structure, comprising an elastic protective sleeve 1, a buffer layer 2 fixedly connected to the inner side of the elastic protective sleeve 1, a wear-resistant layer 3 fixedly connected to the inner side of the buffer layer 2, and a sealing layer 4 fixedly connected to the inner side of the wear-resistant layer 3, with the sealing layer 4 tightly fitted to the glass edge surface; the elastic protective sleeve 1 is made of highly elastic silicone, and its outer wall has anti-slip textures in the shape of diamonds or circles; the buffer layer 2 is made of polyurethane foam, and its thickness is two to five millimeters. The porosity of the buffer layer 2 is 30% to 50%; the wear-resistant layer 3 is made of rubber-modified epoxy resin, and the surface of the wear-resistant layer 3 is coated with an anti-scratch coating with a thickness of 0.1 to 0.3 mm; the sealing layer 4 is made of polytetrafluoroethylene, and the thickness of the sealing layer 4 is 0.5 to 1 mm. The contact surface between the sealing layer 4 and the glass edge is treated with nano-level sealing technology; the elastic protective sleeve 1 and the buffer layer 2 are tightly bonded together with hot melt adhesive, and the elastic protective sleeve 1 covers more than 90% of the outer area of ​​the buffer layer 2.

[0018] Working Principle: The working principle of the aluminum alloy door and window glass edge anti-scratch protection structure is to achieve comprehensive protection of the glass edge through the synergistic effect of multiple composite materials. This structure consists of an elastic protective sleeve 1, a buffer layer 2, a wear-resistant layer 3, and a sealing layer 4. Each layer has a specific function, working together to ensure effective protection of the glass edge under various usage conditions. The elastic protective sleeve 1, as the outermost protective component, is made of highly elastic silicone material. This material has excellent flexibility and elasticity, effectively absorbing and buffering external impacts. When the door or window is subjected to collision or pressure during use, the elastic protective sleeve 1 can quickly deform, dispersing the external force and preventing scratches or damage to the glass edge due to direct impact. The outer wall of the elastic protective sleeve 1 has anti-slip textures, in the shape of diamonds or circles. These textures increase the friction between the protective sleeve and the aluminum alloy door and window frame, ensuring that the protective structure will not slide or shift during use, thereby improving the stability and reliability of the protection. The buffer layer 2, located inside the elastic protective sleeve 1, is made of polyurethane foam material with a thickness of two to five millimeters and a porosity of 30% to 50%. The porous structure of polyurethane foam further absorbs and disperses external forces, reducing the impact on the glass edges. When external force acts on the elastic protective sleeve 1, the buffer layer 2 effectively disperses the impact force over a larger area, thereby reducing the pressure per unit area and further protecting the glass edges from damage. This buffer layer 2 not only enhances the cushioning performance of the protective structure but also improves the overall impact resistance. The wear-resistant layer 3, tightly attached to the inner side of the buffer layer 2, is made of rubber-modified epoxy resin and coated with a scratch-resistant coating 0.1 to 0.3 mm thick. Rubber-modified epoxy resin has good wear resistance and scratch resistance, effectively resisting friction and scratches during daily use. The scratch-resistant coating further enhances the scratch resistance of the wear-resistant layer 3, allowing the glass edges to remain smooth and intact during frequent contact and use. The wear-resistant layer 3 not only prevents the glass edges from being scratched by hard objects but also reduces wear caused by long-term friction, thereby extending the service life of the glass. The sealing layer 4, as the innermost protective component, is made of polytetrafluoroethylene with a thickness of 0.5 to 1 mm. Polytetrafluoroethylene (PTFE) possesses excellent corrosion resistance and a low coefficient of friction, effectively preventing dust, moisture, and other contaminants from entering between the glass edge and the protective structure. The contact surface between the sealing layer 4 and the glass edge is treated with nanoscale sealing technology. This treatment ensures a tight seal between the sealing layer 4 and the glass edge, preventing corrosion and damage from the external environment. Protected by the sealing layer 4, the glass edge can remain clean and dry for a long time, avoiding damage caused by the accumulation of contaminants. The elastic protective sleeve 1 and the buffer layer 2 are tightly bonded together with hot melt adhesive. This bonding method ensures a tight bond between the two layers, improving the stability and reliability of the entire protective structure.The elastic protective sleeve 1 covers more than 90% of the outer area of ​​the buffer layer 2. This design not only enhances the integrity of the protective structure, but also effectively prevents external forces from acting directly on the buffer layer 2, thereby further improving the impact resistance and service life of the protective structure.
