Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of anticorrosive coating, specifically to an anticorrosive coating composite coating. BACKGROUND

[0002] The adhesion between the base coating of the traditional anticorrosive coating and the metal to be protected is poor, which leads to easy peeling of the coating and inability to provide durable and stable protection. Moreover, the coating film formed by some base coatings has poor flexibility or unreasonable thickness, affecting the overall anticorrosive effect. At the same time, the connection between the coating and the base layer is not firm enough. The surface of the conventional coating is relatively smooth. During long-term use, the coating is at high risk of peeling off from the base layer due to environmental factors, which seriously affects the reliability and stability of the anticorrosive coating. In terms of anticorrosive performance, most anticorrosive coatings are difficult to effectively resist complex chemical corrosion and harsh weather conditions. The existing anticorrosive materials either lack chemical stability and cannot resist the corrosion of external chemical substances for a long time, or have limited rust resistance and are difficult to fully protect the metal. Moreover, the single anticorrosive layer structure is obviously insufficient in protection ability when facing high-strength corrosive environments. Wear resistance is also a major shortcoming of existing anticorrosive coatings. In actual use, the coating is often subjected to mechanical effects such as friction and impact. Ordinary anticorrosive coatings are easily damaged under these external forces due to poor wear resistance, which in turn leads to a decrease in anticorrosive performance and shortens the service life of the coating. In addition, in some special environments such as high-temperature environments, the existing anticorrosive coating lacks effective heat insulation measures and cannot block heat transfer, which can cause the surface temperature of the coated object to be too high, resulting in thermal stress and causing the coating to crack and peel off due to thermal expansion and contraction. This seriously affects the application of the anticorrosive coating in special working conditions. Moreover, in many special situations, post-spraying cannot be performed, and when the original paint surface falls off, the panel must be removed, which is a waste.

[0003] A steel structure anticorrosive coating structure (authorized publication number CN209849223U) is disclosed in a Chinese patent, which includes a metal coating, a base coating, a middle coating, a putty layer, and a topcoat layer coated on the steel structure in sequence. The surface of the topcoat layer and the putty layer is coated with a waterproof thickening layer. This utility model has the advantage of ensuring the anticorrosive effect of the anticorrosive coating on the steel structure.

[0004] The anticorrosive coating structure of the patent mainly protects against the problem of damage in the later processing of the steel structure, and the design and consideration in the wear resistance aspect are relatively insufficient, and if the steel structure faces frequent friction and wear environment in the use process, the anticorrosive coating may not be able to provide good wear protection, and the heat transfer is blocked by the lack of a heat insulation layer, so that the surface temperature of the coated object is increased in the use process, the influence of thermal stress on the coating and the coated object is increased, and the problems of coating cracking and peeling caused by thermal expansion and cold contraction are caused, and the adhesion between the anticorrosive metal is not stable enough, and the coating is prone to fall off, so that the durable and stable protection cannot be provided, and the overall anticorrosive effect is affected, therefore, the utility model provides an anticorrosive coating composite coating to solve the problems mentioned above.
