Problems solved by technology

[0003] Today's common coatings are prone to thermal degradation and carbonization under high temperature conditions, and cannot protect the substrate. However, high temperature resistant coatings can maintain high temperature without being brittle, peeling off from the substrate, or bubbling. Certain physical, chemical and mechanical properties enable objects to avoid adverse conditions such as chemical corrosion and thermal oxidation corrosion at high temperatures. It is a technical problem to be solved urgently by those skilled in the art to develop a coating that can effectively protect the hydraulic oil tank in the hydraulic system.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a corrosion-resistant coating for protecting a hydraulic oil tank and a preparation method thereof. Background technique [0002] With the continuous development of my country's modern industry, especially in metallurgy, petrochemical, energy, new materials and hydraulic casting industries, more and more high-temperature equipment and supporting facilities are used. Oxygen oxidizes and causes corrosion, which causes metal materials to gradually lose their strength and lead to structural loss, which becomes a hidden danger of various accidents. Therefore, the surface of high-temperature equipment generally needs to be protected with high-temperature resistant anti-corrosion coatings to prevent oxidation and corrosion of metal materials and prolong the service life of high-temperature equipment; specifically, the hydraulic oil tank in the hydraulic system is easily corro...
