NOVELTY - Wear-resistant coating comprises carbon nitride, silicon nitride and nano-titanium dioxide in the weight ratio of 1:1:2. USE - Wear-resistant coating. ADVANTAGE - The wear-resistant coating has improved anti-corrosion performance, flexibility, impact resistance and wear resistance, and is not easy to crack. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a wear-resistant coating, involing: a. mixing the initiator and solvent to obtain the diluted initiator; b. dripping the diluted initiator in the acrylic acid monomer, heating and reacting to obtain polyacrylic acid; c. mixing polyacrylic acid prepared, epoxy resin, adding ethylenediamine and graphene, adjusting the pH value, heating the oxidized graphene modified epoxy acrylic acid copolymer; and d. adding emulsifying agent and water in the graphene modified epoxy acrylic acid copolymer prepared and heating the graphene modified epoxy acrylic acid emulsion.
