Abstract

The invention discloses a strong-strength abrasion-resistant coating. The coating is characterized in that the coating is prepared from the following raw materials in parts by weight: 20 parts of tetraethyl orthosilicate, 15 parts of methyltrimethoxy silane, 15 parts of calcium naphthenate, 3 parts of silicon dioxide sol, 7 to 13 parts of graphite powder, 15 parts of auxiliary, 5 parts of carbon fiber powder and 6 parts of silicon carbide, wherein the particle size of the silicon dioxide sol is 5nm, the particle size of silicon oxide crystals is 25 mu m, the weight ratio of the silicon dioxide sol to the silicon oxide crystals is 2:3, and the weight ratio of the tetraethyl orthosilicate to the methyltrimethoxy silane is 2:1. The strong-strength abrasion-resistant coating disclosed by the method is high in abrasion resistance and lower in cost, and the adhesion performance of the strong-strength abrasion-resistant coating with a substrate is high.

Description

technical field [0001] The invention belongs to the technical field of materials, 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 ...
