Technical Field
[0001] The utility model relates to the technical field of metal product processing, and more specifically to an anti-corrosion coating structure for metal products. Background Art
[0002] Traditional metal products are prone to corrosion in harsh environments such as humidity and salt spray, resulting in a decline in mechanical properties and a shortened service life.
[0003] Although existing anti-corrosion coating technologies can delay corrosion to a certain extent, they often have problems such as insufficient adhesion and poor weather resistance.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies to provide an anti-corrosion coating structure for metal products, with the aim of achieving a more practical value. Summary of the Invention

The device main body includes a metal product body, and an anti-corrosion coating structure body is arranged on the metal product body. The anti-corrosion coating structure body includes a microporous ceramic reinforcing layer, a bottom layer, an intermediate layer, and a surface layer. The bottom layer is composed of an epoxy zinc yellow primer with high adhesion and is coated on the surface of the metal product body. The intermediate layer includes at least two layers of coatings with different functions. The first layer is an epoxy mica iron intermediate paint, and the second layer is a polyurethane elastic intermediate paint, which are successively coated on the bottom layer. The surface layer is composed of a fluorocarbon coating and is coated on the intermediate layer. The microporous ceramic reinforcing layer is arranged between the bottom layer and the metal product body and has a microporous structure to enhance the adhesion between the coating and the substrate of the metal product body and block corrosive media. The multi-layer composite design is combined with the microporous ceramic reinforcing layer to effectively block the penetration of corrosive media and improve the corrosion resistance of the coating. The combined action of the high-adhesion primer and the microporous ceramic reinforcing layer ensures the firm bonding between the coating and the metal substrate and prevents the coating from falling off. The application of the polyurethane elastic intermediate paint and the fluorocarbon coating makes the coating have good weather resistance and wear resistance and can adapt to various harsh environments.
[0007] Further, a repair layer is provided in the intermediate layer.
[0008] Further, the epoxy zinc yellow primer, the epoxy mica iron intermediate paint, the polyurethane elastic intermediate paint, and the fluorocarbon coating are successively coated and dried and cured through a coating process to form a continuous coating structure.
[0009] Furthermore, the microporous ceramic reinforcing layer is formed on the surface of the substrate of the metal product body by spraying, dipping or electrophoresis, and is tightly combined with the subsequent coating.
