Composite material and preparation method thereof, wear-resistant anticorrosive coating and application

The invention relates to the field of materials, and particularly discloses a composite material and a preparation method thereof, a wear-resistant anticorrosive coating and application. The compositematerial comprises a component A and a component B. The component A is prepared from the following raw materials in parts by weight: 5-10 parts of antirust pigment and 90-110 parts of fluorine-silicon anticorrosive paint. The component B is prepared from the following raw materials in parts by weight: 20-50 parts of nanoscale silicon carbide powder, 70-110 parts of fluorine-silicon anticorrosivepaint and 0.1-2 parts of a silane coupling agent. The composite material provided by the invention has excellent wear resistance and corrosion resistance, can be quickly cured at normal temperature, can be used in ultralow-temperature and high-temperature environments, and has high chloride ion corrosion resistance. The preparation method provided by the invention is simple, the prepared compositematerial can be used for a
