[0023] The specific implementation of the utility model will be further described below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the utility model, and cannot be used to limit the protection scope of the utility model.

[0024] The "surface" is used as a reference to the normal use state of the thermal insulation reinforced aluminum foil glass fiber composite cloth, and is only used for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element indicated must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0025] In addition, the terms "first", "second", and the like are only used for description purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and the like can explicitly or implicitly include one or more of the features.

[0026] As shown in Figures 1-2 The thermal insulation reinforced aluminum foil glass fiber composite cloth includes an inorganic high-temperature-resistant layer 1, an aluminum foil layer 2, and a polyester layer 3. The inorganic high-temperature-resistant layer 1 has a first surface (not labeled) and a second surface (not labeled) opposite along the thickness direction, the aluminum foil layer 2 is arranged on the first surface, and the inorganic high-temperature-resistant layer 1 includes a glass fiber layer 11 and a ceramic fiber layer 12.

[0027] As shown in Figure 1 In some embodiments, the polyester layer 3 is sandwiched between the aluminum foil layer 2 and the inorganic high-temperature-resistant layer 1.

[0028] In some embodiments, the polyester layer 3 is arranged on the second surface of the inorganic high-temperature-resistant layer 1.

[0029] In other embodiments, the polyester layer 3 is arranged between the aluminum foil layer 2 and the inorganic high-temperature-resistant layer 1, and on the second surface of the inorganic high-temperature-resistant layer 1.

[0030] Further, the polyester layer 3 is a polyethylene terephthalate film (PET film), which has good tensile strength and tear strength, can effectively supplement the brittleness problem that may exist in the aluminum foil glass fiber cloth, especially in a low temperature environment; the flexibility and ductility of the PET film make the composite material more easily bent and formed, suitable for complex geometric shapes; the PET film usually has excellent ultraviolet (UV) resistance and oxidation resistance, which helps to protect the internal aluminum foil and glass fiber from external environmental factors, prolonging the service life; the PET film as a barrier layer can effectively prevent moisture penetration, keeping the internal materials dry, which is very important for applications that require waterproof and moisture-proof; the PET film itself is a good electrical insulator, when combined with the aluminum foil glass fiber cloth, it can further strengthen the overall electrical insulation performance without affecting the electromagnetic shielding effect.

[0031] Ceramic fiber cloth is a high-performance refractory material with a continuous operating temperature of up to 1000℃ and a short-term operating temperature of up to 1260℃. It exhibits excellent resistance to acids and alkalis and can withstand the corrosion of molten metals such as aluminum and zinc. Its low thermal conductivity provides excellent thermal insulation, enhancing the overall insulation performance of the composite cloth. It also maintains good electrical insulation properties even at high temperatures. When used in combination with aluminum foil fiberglass cloth, it further enhances the insulation effect. The combination of ceramic fiber cloth and aluminum foil fiberglass cloth provides superior insulation performance; the aluminum foil reflects heat, while the ceramic fibers prevent heat conduction, resulting in a synergistic effect that significantly improves insulation efficiency. It also increases structural strength; the high strength and toughness of the ceramic fiber cloth help improve the overall mechanical properties of the composite material, making it more durable. Combining the advantages of both materials, it provides excellent high-temperature resistance as well as good waterproofing, moisture resistance, and corrosion resistance. For applications requiring good electrical insulation, such as around electrical equipment, the composite material offers enhanced safety.

[0032] Therefore, the inorganic high-temperature resistant layer 1, which combines glass fiber layer 11 and ceramic fiber layer 12, improves the thermal insulation, fire resistance and mechanical properties of the composite fabric; and the polyester layer 3 further improves the brittleness of the glass fiber fabric.

[0033] The glass fiber layer 11 and the ceramic fiber layer 12 are fixed together by sewing together refractory fiber yarn or steel wire. Further, the refractory fiber yarn is one of ceramic fiber yarn, aluminosilicate fiber yarn, aramid fiber yarn, glass fiber yarn, and basalt fiber yarn.

[0034] like Figure 1 As shown, in some embodiments, the inorganic high-temperature resistant layer 1 is a laminated structure of glass fiber layer 11 / ceramic fiber layer 12, which is a laminated structure one.

[0035] like Figure 2 As shown, in some embodiments, the inorganic high-temperature resistant layer 1 is a laminated structure of glass fiber layer 11 / ceramic fiber layer 12 / glass fiber layer 11, which is a second laminated structure. This laminated structure of inorganic high-temperature resistant layer 1 has better overall performance and is more economical.

[0036] In some embodiments, the inorganic high-temperature resistant layer 1 is a laminated structure of ceramic fiber layer 12 / glass fiber layer 11 / ceramic fiber layer 12, which, although costly, has superior fire resistance and high-temperature resistance.

[0037] To improve the wear resistance of the inorganic high-temperature resistant layer 1, such as... Figures 1-2 As shown, in some embodiments, the second surface of the inorganic high-temperature resistant layer 1 is provided with a polyurethane coating 4.

[0038] In some embodiments, a polyurethane coating 4 is provided between the inorganic high-temperature resistant layer 1 and the polyester layer 3. The polyurethane coating 4 improves the toughness of the inorganic high-temperature resistant layer 1.

[0039] The aluminum foil layer 2, the inorganic high-temperature-resistant layer 1 and the polyester layer 3 are connected by the high-temperature-resistant adhesive layer 10, and the high-temperature-resistant adhesive layer 10 is a polyurethane modified epoxy resin adhesive. The polyurethane modified epoxy resin adhesive enhances the flexibility of the composite cloth, the epoxy resin itself has good heat resistance and can remain stable at high temperatures, but it is also relatively brittle and hard. The polyurethane has good elasticity and flexibility, and through modification, it can significantly improve the flexibility and impact resistance of the adhesive while maintaining a certain strength, and is particularly suitable for application occasions that need to withstand vibration or bending stress; the modified adhesive generally exhibits better ultraviolet (UV) resistance and oxidation resistance, making it more stable and durable in outdoor environments and less prone to aging and yellowing; the polyurethane component helps to increase the wettability and adhesion to different substrate surfaces, especially when dealing with materials such as plastics and rubbers that are difficult to bond.

[0040] As shown in FIG. 1, in some embodiments, the polyurethane coating layer 4 is provided with a mounting adhesive layer 5 away from the surface of the inorganic high-temperature-resistant layer 1. Figures 1-2

[0041] In other embodiments, the polyester layer 3 is provided with a mounting adhesive layer 5 away from the surface of the inorganic high-temperature-resistant layer 1.

[0042] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the scope of protection of the present application.​
