▎ 摘　　要

NOVELTY - Composite coating with anti-corrosion function includes modified titanium nano, graphene oxide, epoxy resin, silane coupling agent, dispersion medium, auxiliary agent and solvent, where the weight ratio of the modified titanium nano, graphene oxide and epoxy resin is 1:0.2-5:15-500. The modified titanium nanometer is a nanometer titanium element modified by a silane coupling agent. USE - Composite coating with anti-corrosion function. ADVANTAGE - The composite coating with anti-corrosion function is provided with inorganic titanium nanoparticles that are uniformly loaded on the surface of graphene oxide by covalent grafting, and the structure of graphene oxide is changed to transform from a densely packed state to a loose and easily dispersed state, and greatly improve its dispersion in coatings, and the anti-corrosion performance of the coating is improved, and it has the characteristics of being suitable for industrial applications. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing composite coatings, which involves mixing the modified titanium nano, graphene oxide, epoxy resin, silane coupling agent, dispersion medium, auxiliary agent and solvent to obtain a mixture, and homogenizing the mixture to obtain the composite coating.
