Abstract

A refractory antiwear lubricating paint is prepared from thermosetting epoxy resin, boron modified phenolic resin, MoS2, Sb2O3 and cerium fluoride. Its advantages are high antiwear, load-bearing and lubricating performance, and excellent refractory performance.

Description

technical field [0001] The invention relates to a high-temperature-resistant and wear-resistant lubricating coating and a preparation method thereof. Background technique [0002] Epoxy resin is a good adhesive with good adhesion, high cohesive strength, and small creep shrinkage. It belongs to thermosetting organic resin, but due to its own structural characteristics, its high temperature resistance is poor. Under this condition, not only carbonization but also ashing occurs, thus limiting its scope of use to a large extent. The performance of epoxy resin depends on the performance of curing agent to a large extent, and the development of a new curing agent is equal to the development of a new epoxy resin. In addition, in many specific applications of epoxy resin, a variety of additives must be added, and various components may have certain physical and chemical interactions with each other. Often, a single performance is improved, while the overall performance is reduced,...
