Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a composite high-temperature-resistant and wear-resistant protective film. Background Art

[0002] Protective films can be divided into digital product protective films, car protective films, household protective films, food preservative protective films, etc. according to their uses. Protective films can be divided into the following fields according to their application scope: metal product surfaces, coated metal product surfaces, plastic product surfaces, automotive product surfaces, electronic product surfaces, sign product surfaces, profile product surfaces, and other product surfaces.

[0003] The existing protective film has a simple structure and no corresponding wear-resistant structure on the surface. Therefore, the overall wear resistance and temperature resistance are poor when it is laid and used, and it is easy to be damaged or fail during actual use.

[0004] Therefore, in view of the above problems, it is necessary for the applicant to design a composite high temperature resistant and wear resistant protective film to solve the problem. Summary of the invention

[0005] The purpose of the utility model is to provide a composite high temperature resistant and wear resistant protective film to solve the problems mentioned in the above background technology.

[0007] Furthermore, the wear-resistant film is made of wear-resistant resin, and the outer side of the wear-resistant resin is coated with epoxy resin paint.

[0008] Through the above structural design, epoxy resin refers to a general term for low molecular weight substances containing two or more epoxy groups in the molecular structure and their cross-linked cured products. The cured epoxy resin usually has excellent alkali resistance, acid resistance and solvent resistance.

[0009] Furthermore, the wear-resistant resin is preferably polyurethane resin.

[0010] Through the above structural design, the polyurethane resin has a unique molecular structure and chemical properties, thus having good wear resistance. When subjected to friction and wear, the polyurethane resin can maintain good stability and durability, thereby extending the service life of the material.

[0011] Furthermore, the flame retardant layer enters the interlayer of the heat insulation film and the wear-resistant film by compacting and filling flame retardant particles, and the material of the flame retardant particles is alumina ceramic powder.

[0012] Through the above structural design, alumina ceramic is a high-temperature resistant ceramic material with excellent fire resistance and flame retardant properties. At a temperature as high as 1200 degrees Celsius, alumina ceramic can still maintain its working performance without being affected. This characteristic enables the protective film to have broad application potential in high-temperature environments and strong high-temperature resistance ability.

[0013] Furthermore, the material of the heat insulation film is asbestos.

[0014] Through the above structural design, asbestos is a natural mineral fiber with excellent high-temperature resistance performance, which is convenient for improving the high-temperature resistance performance of the protective film.

[0015] Furthermore, the temperature-resistant layer is a polyimide film, and a phosphate aluminum powder coating is applied on the outer side of the polyimide film.

[0016] Through the above structural design, the polyimide film is formed by low-temperature polycondensation of dianhydride and diamine in a polar solvent to produce soluble polyamic acid, and then by heating and dehydration. It has extremely high thermal stability, and the decomposition temperature can reach 550 - 600 °C.

[0017] Compared with the prior art, the beneficial effects of the present utility model are: This composite high-temperature resistant and wear-resistant protective film is wear-resistant and high-temperature resistant, has a wide range of applications, and is not prone to breakage or failure during actual use. The specific content is as follows:

[0018] 1. Polyurethane resin and epoxy resin are provided. Polyurethane resin has a unique molecular structure and chemical properties, and thus has good wear resistance. When polyurethane resin is subjected to friction and wear, it can maintain good stability and durability, thereby extending the service life of the material. Epoxy resin refers to the general term of low molecular weight substances containing two or more epoxy groups in the molecular structure and their cross-linked cured products. The cured epoxy resin usually has excellent alkali resistance, acid resistance and solvent resistance, which will improve the wear resistance of the protective film, thereby improving the service life and application range of the protective film.

[0019] 2. It is provided with a heat insulation film, a flame retardant layer and a temperature resistant layer. The heat insulation film is made of asbestos, which is a natural mineral fiber with excellent high temperature resistance performance, facilitating the improvement of the high temperature resistance performance of the protective film.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 - 4 shown, a composite high temperature resistant and wear-resistant protective film of the present utility model includes an inner core layer 3, and the inner core layer 3 is an aluminum wire mesh woven by multiple strands of aluminum wires. The aluminum wire mesh facilitates the improvement of the toughness and anti-fracture ability of the protective film. Temperature resistant layers 2 are provided on both sides of the inner core layer 3, and the inner side of the temperature resistant layer 2 is in contact with the outer surface of the inner core layer 3. Wear-resistant layers 1 are provided on both sides of the temperature resistant layer 2, and the wear-resistant layer 1 is sequentially provided with a heat insulation film 6, a flame retardant layer 5 and a wear-resistant film 4 from the inside out. The inner side of the heat insulation film 6 is in contact with the outer side of the temperature resistant layer 2.

[0027] The material of the wear-resistant film 4 is wear-resistant resin, and an epoxy resin coating is applied on the outer side of the wear-resistant resin. Epoxy resin refers to the general term for low-molecular-weight substances containing two or more epoxy groups in the molecular structure and their cross-linked cured products. The cured epoxy resin usually has excellent alkali resistance, acid resistance and solvent resistance. The wear-resistant resin is preferably polyurethane resin. Polyurethane resin has a unique molecular structure and chemical properties, thus having good wear resistance. When polyurethane resin is subjected to friction and wear, it can maintain good stability and durability, thereby extending the service life of the material.

[0028] The flame retardant layer 5 enters the interlayer of the heat insulation film 6 and the wear-resistant film 4 by compacting and filling flame retardant particles. The material of the flame retardant particles is alumina ceramic powder. Alumina ceramic is a high-temperature resistant ceramic material with excellent fire resistance and flame retardant performance. At a temperature as high as 1200 degrees Celsius, alumina ceramic can still maintain its working performance unaffected. This characteristic makes the protective film have broad application potential in high-temperature environments and strong high-temperature resistance. The material of the heat insulation film 6 is asbestos. Asbestos is a natural mineral fiber with excellent high-temperature resistance, which is convenient for improving the high-temperature resistance of the protective film. The temperature-resistant layer 2 is a polyimide film, and a phosphate aluminum powder coating is applied on the outer side of the polyimide film. The polyimide film is formed by low-temperature polycondensation of dianhydride and diamine in a polar solvent to produce soluble polyamic acid, and then by heating and dehydrating. It has extremely high thermal stability, and the decomposition temperature can reach 550-600°C. Phosphate aluminum powder, as an inorganic compound, has high chemical stability. In a high-temperature environment, it can maintain good structural stability and is not easy to react with common corrosive media, thereby protecting the protective film from damage.
