In order to improve the friction and wear performance of steel under severe service conditions such as high temperature, epoxy resin E-51 resin is used as the base material, graphite, MoS 2 and other high temperature wear-resistant materials are used as pigments to prepare a kind of oil-coated high temperature resistant paint. The entropy weight method is used to comprehensively evaluate high temperature wear, thermal weight loss rate, and corrosion current density. The results show that the coating optimized by the entropy weight method has excellent performance. Among them, the high temperature wear rate of the paint film is 0.83%, the thermal weight loss rate at 200 °C is 4.56%, the thermal weight loss rate at 400 °C is 27.84%, and the corrosion current density is 9.31E-9. The alkali resistance of the paint film is far greater than the national standard.
