Abstract

The invention discloses a high-strength wear-resistant paint which is prepared from the following raw materials in parts by weight: 20-30 parts of tetraethoxysilane, 15-25 parts of methyl trimethoxysilane, 15-20 parts of calcium naphthenate, 3-5 parts of silica sol, 10-15 parts of crystallized silicon oxide, 7-13 parts of graphite powder and 15-20 parts of auxiliary material, wherein the particle size of the silica sol is 4-9 nm, the particle size of the crystallized silicon oxide is 25-35 mu m, the weight ratio of the silica sol to the crystallized silicon oxide is 2:(5-6), and the weight ratio of the tetraethoxysilane to methyl trimethoxysilane is (1-2):1. The high-strength wear-resistant paint is excellent in crocking resistance, good in adhesion property with a substrate, and lower in cost.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-strength wear-resistant coating. 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, sandstone and water flow and the action of mechanical force, the wear of the material is quite serious. In order to prolong the service life, the surface of the material needs to be coated with wear-resistant coatings. Wear-resistant functional coatings are the core of the new coating field. It plays an important role in promoting and supporting the development of technology. In the research field of the global modern coatings industry and technology, wear-resistant functional coatings account for 25-35%, and h...
