Abstract

The invention relates to the technical field of coatings, in particular to a preparation method of a wear-resistant coating. The preparation method of the wear-resistant coating comprises the steps ofS1, adding hemp fiber into potassium periodate solution for shaded reaction, then immersing the reacted hemp fiber into glycerol solution, washing the immersed hemp fiber through deionized water, anddrying the washed hemp fiber to obtain modified hemp fiber; S2, mixing and dissolving lignin into dioxane aqueous solution, adding the modified hemp fiber for mixed reaction to obtain a wear-resistant agent; S3, heating a solvent, then uniformly mixing butyl acrylate, silicon dioxide, ethyl cellulose, polyester resin, the wear-resistant agent, polyacrylic acid, silicon carbide, glass fiber and afilm-forming agent, and increasing and keeping the temperature to obtain the wear-resistant coating. The prepared wear-resistant coating is excellent in wear resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of wear-resistant coatings. Background technique [0002] With the development of modern science and technology, artificial satellites, spacecraft, high-speed trains, impellers of steam turbines and engines, propellers of ships, blades of hydroelectric generators, decks of ships, floors of buildings, road marking paint, etc. The erosion of high-speed airflow, sand and water flow and the action of mechanical force make the wear of the material very serious. In order to prolong the service life, the surface of the material needs to be coated with wear-resistant coatings. Wear-resistant coatings are the core of the new coating field. The development of technology plays an important role in promoting and supporting. In the research field of the global modern coatings industry and technology, wear-resistant coatings account for 25-35%, and have become the focus ...
