Problems solved by technology

[0006] At present, the wear resistance of the existing coatings is average, and the coatings are often subject to friction in some exposed parts, and the coatings are easy to wear. In the prior art, the coatings commonly used increase the wear resistance of equipment parts, but at 600 ° C There are many deficiencies in the wear resistance, gloss, adhesion and other properties of coatings in the following wear-prone environments. Wear is frequent and inevitable. Research on wear and wear-resistant materials has important application value. With the rapid development of science and technology With the development and continuous progress of society, the application of high-performance wear-resistant coatings will receive more and more attention

Abstract

The invention discloses abrasion-resistant paint and a preparation method thereof. The paint comprises a first component and a second component, wherein the first component is double-component composition formed by mixing of a component A and a component B in a ratio of 1:1, the component A in the first component comprises components as follows: E-20 epoxy resin, silicon carbide micro powder, carbon monofluoride and a coupling agent; the component B in the first component comprises components as follows: methyl methacrylate, butyl acrylate, aluminum isopropoxide, triethoxy vinyl silane and 20-25 parts of a solvent; the second component comprises components as follows: a curing agent, an antifoaming agent, a leveling agent and a solvent. The components A and B in the first component are prepared separately and then mixed, and finally, the first and second components are cured to obtain the abrasion-resistant paint.

Description

Technical field [0001] The invention is a coating technology field, which involves a wear -resistant coating and its preparation methods. Background technique [0002] With the advancement and development of science and technology, new materials, as one of the three major industries of the 21st century, are obviously particularly important. To a certain extent, it also represents the country's industrial progress and development.one. [0003] The coating is a type of liquid or solid material that is coated on the surface of the object to form a film to protect, decorate, or other special functions, such as insulation, rust, mold, heat resistance, etc.There are many types of coatings, and the special features that can be achieved by different formulas are different. [0004] At present, the wear -resistant coatings on the market are mainly used in the steel industry and the machinery industry. Wearing is often encountered in high -speed operations. The equipment will fail, damage,...
