Abstract

The invention discloses a wear-resisting coating. The wear-resisting coating comprises the following raw materials in parts by weight: 20-30 parts of vinyl triisopropoxysilane, 3-5 parts of silicon dioxide aerogel, 15-20 parts of trioxane, 5-9 parts of water, 3-7 parts of acetic anhydride, 10-15 parts of acetylcholine, 0.1-0.3 part of polyoxyethylene anhydro-sorbit monoglyceride, 10-15 parts of crystallizing silicon oxide, and 7-13 parts of graphite powder, wherein the porosity of the silicon dioxide aerogel is 75-79%, and the weight ratio of silicon dioxide aerogel to vinyl triisopropoxysilane is 1:(5-7). The wear-resisting coating can improve the degree of crosslinking of a coating and enhance the resistance to scratching, and has low cost.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a 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, 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 of research and develop...
