[0002] The coating that can play a role of heat insulation when applied on the surface to be constructed is called thermal insulation coating. Coating, in traditional Chinese, is called paint. The so-called coating is applied on the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the object to be coated. It is usually a viscous liquid made of resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, and prepared with organic solvents or water.

At the same time, a ceramic particle layer is arranged on the inside. The ceramic particle layer has a purification function and is also resistant to corrosion.

[0008] Preferably, a heat insulating layer is provided between the primer layer and the waterproof layer, and the heat insulating layer comprises an acrylate polymer layer filled with bubble quartz powder.

[0009] By adopting the above technical solution, the acrylate cross-linked polymer can maintain stability in a high temperature environment and is not easy to soften or melt; it is arranged between the primer layer and the waterproof layer, which can effectively protect the thermal insulation layer, so that the thermal insulation performance of the corresponding wall decays more slowly.

[0010] Preferably, the primer layer comprises a silicone primer layer and coarse particles are mixed therein.

[0011] Preferably, the waterproof layer comprises a polysiloxane waterproof layer, and the thickness of the waterproof layer is 0.1 mm-0.3 mm.

[0012] By adopting the above technical solution, the polysiloxane waterproof layer has the advantages of slow curing when the humidity is low and fast curing when the humidity is high. It is often used in waterproof coatings to improve the waterproof performance of the coating structure.

[0013] Preferably, the temperature-resistant layer comprises a silicone high-temperature paint layer with a thickness of 0.2 mm to 0.4 mm.

[0017] By adopting the above technical solution, the first wear-resistant layer and the second wear-resistant layer have burrs at the bonding position, which can make the two layers fit more tightly. At the same time, the first wear-resistant layer includes a wear-resistant particle layer, which also enables the two to be more stably bonded together when compounded, thereby improving the wear resistance.

[0018] Preferably, the wear-resistant particle layer includes an organic silicon wear-resistant layer and particles contained therein.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

At the same time, a ceramic particle layer is arranged on the inside. The ceramic particle layer has a purification function and is also resistant to corrosion. The two layers are compounded together, and the surface of the ceramic particle layer is not a smooth surface, so that the two layers can be tightly bonded together, and the acid and alkali resistance is better.

[0021] The first wear-resistant layer and the second wear-resistant layer have burrs at the bonding position, which can make the two layers fit more closely. At the same time, the first wear-resistant layer includes a wear-resistant particle layer, which also enables the two to be more stably bonded together when compounded, thereby improving the wear resistance.
