[0002] Door and window sealing strips are a type of sealing strip mainly used in building decoration doors and windows such as PVC doors and windows, aluminum alloy doors and windows, and wooden doors and windows. PVC door and window sealing strips on the market are generally extruded from materials such as PVC, modified PVC, EPDM, elastomer sealing strips, and silicone.

[0003] Existing sealing strips are usually installed inside the door and window frames. Because doors and windows are frequently opened and closed, the sealing strips are easily worn, resulting in poor sealing and dustproof performance. Furthermore, the sealing strips are exposed to the air and are prone to aging due to environmental factors, thus reducing their service life. Therefore, a high-sealing and dustproof sealing strip is proposed to address the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0027] This application discloses a high-sealing dustproof sealing strip. (See also...) Figure 1 , Figure 2 and Figure 3 A high-sealing dustproof sealing strip includes a sealing strip body 1, a sealing strip body 1 including a limiting shell 2, an adhesive layer 3 at the bottom of the limiting shell 2, an arc-shaped sealing gasket 4 in the inner cavity of the limiting shell 2, a sealing baffle 5 in the inner cavity of the arc-shaped sealing gasket 4, slots 6 on both sides of the limiting shell 2, and sealing cover plates 7 rotatably connected to both sides of the limiting shell 2 via a rotating shaft. An insert 8 is provided on one side of the sealing cover plate 7, and the surface of the insert 8 is inserted into the inner wall of the slot 6.

[0028] The arc-shaped sealing gasket 4 includes a base layer 41, a protective layer 42 on the surface of the base layer 41, a reinforcing layer 43 on the surface of the protective layer 42, and a protective layer 44 on the surface of the reinforcing layer 43. By setting the protective layer 42, the crack resistance and freeze resistance of the sealing strip body 1 can be improved. By setting the reinforcing layer 43, the high temperature resistance and corrosion resistance of the sealing strip body 1 can be improved. By setting the protective layer 44, the oxidation resistance and wear resistance of the sealing strip body 1 can be improved, avoiding wear of the sealing strip body 1 caused by opening and closing doors and windows, thereby improving the sealing and dustproof performance of the sealing strip body 1.

[0029] Reference Figure 3 and Figure 4The protective layer 42 includes a crack-resistant layer 4201, and an antifreeze layer 4202 is provided on the surface of the crack-resistant layer 4201. The crack-resistant layer 4201 is a polyurethane coating, and the antifreeze layer 4202 is a fluororubber coating. By setting the crack-resistant layer 4201 made of polyurethane coating, the polyurethane coating has a certain degree of flexibility, which can adapt to the deformation of the sealing strip during use and maintain good performance, thus preventing the sealing strip body 1 from cracking after long-term use. By setting the antifreeze layer 4202 made of fluororubber coating, the fluororubber coating has excellent weather resistance, which can maintain stable performance under extreme climatic conditions and is not easily corroded by ultraviolet rays, oxidation or chemicals, thereby improving the antifreeze performance of the sealing strip body 1.

[0030] Reference Figure 3 and Figure 5 The reinforcing layer 43 includes a high-temperature resistant layer 4301, and a corrosion-resistant layer 4302 is provided on the surface of the high-temperature resistant layer 4301. The high-temperature resistant layer 4301 is a graphite coating, and the corrosion-resistant layer 4302 is a fluoropolymer coating. By providing the high-temperature resistant layer 4301 made of graphite coating, the graphite coating usually has high high-temperature resistance, which can improve the high-temperature resistance of the sealing strip body 1. By providing the corrosion-resistant layer 4302 made of fluoropolymer coating, the fluoropolymer coating has excellent resistance to many chemicals, including acids, alkalis, solvents, etc., which can improve the corrosion resistance of the sealing strip body 1.

[0031] Reference Figure 3 and Figure 6 The protective layer 44 includes an antioxidant layer 4401, and a wear-resistant layer 4402 is provided on the surface of the antioxidant layer 4401. The antioxidant layer 4401 is an acrylic coating, and the wear-resistant layer 4402 is a ceramic coating. By setting the antioxidant layer 4401 made of acrylic coating, the acrylic coating has good weather resistance and can maintain its color and appearance for a long time. It is not easy to fade or yellow, thus avoiding aging and damage to the sealing strip body 1. By setting the wear-resistant layer 4402 made of ceramic coating, due to the addition of ceramic particles, the ceramic coating usually has excellent wear resistance, which can effectively protect the surface of the substrate from wear and prevent the sealing strip body 1 from being worn due to frequent opening and closing of doors and windows, thereby improving the high sealing and dustproof performance of the sealing strip body 1.

[0032] Reference Figure 1 and Figure 2 The limiting shell 2 and the sealing cover 7 are both made of plastic, and the arc-shaped sealing gasket 4 and the sealing baffle 5 are integrally molded structures. The integrally molded arc-shaped sealing gasket 4 and sealing baffle 5 can improve the sealing performance and service life of the sealing strip body 1.

[0033] Working Principle: During use, a crack-resistant layer 4201 made of polyurethane coating is applied. Polyurethane coating has a certain degree of flexibility, which can adapt to the deformation of the sealing strip during use and maintain good performance, preventing cracking of the sealing strip body 1 after prolonged use. An antifreeze layer 4202 made of fluororubber coating is applied. Fluororubber coating has excellent weather resistance and can maintain stable performance under extreme climatic conditions, and is not easily corroded by ultraviolet rays, oxidation, or chemicals, thus improving the antifreeze performance of the sealing strip body 1. A high-temperature resistant layer 4301 made of graphite coating material is applied. Graphite coating typically has high high-temperature resistance, which can improve the high-temperature resistance of the sealing strip body 1. A corrosion-resistant layer 4302 made of fluoropolymer coating material is applied. The fluoropolymer coating is resistant to corrosion from many chemicals. The materials used have excellent resistance to various substances, including acids, alkalis, and solvents, which can improve the corrosion resistance of the sealing strip body 1. By setting an anti-oxidation layer 4401 of acrylic ester coating material, the acrylic ester coating has good weather resistance and can maintain its color and appearance for a long time, and is not prone to fading or yellowing, thus avoiding aging and damage to the sealing strip body 1. By setting a wear-resistant layer 4402 of ceramic coating material, due to the addition of ceramic particles, the ceramic coating usually has excellent wear resistance, which can effectively protect the substrate surface from wear and prevent the sealing strip body 1 from being worn due to frequent opening and closing of doors and windows, thereby improving the high sealing and dustproof performance of the sealing strip body 1. At the same time, the setting of the insert 8 and the slot 6 makes it convenient for staff to disassemble and replace the arc-shaped sealing gasket 4 and the sealing baffle 5, thereby improving maintenance efficiency.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
