NOVELTY - Preparation of graphene-based anticorrosive paint involves reducing graphene, adding a stabilizer, performing π-π interaction to obtain dispersed and stable graphene nanosheets, hydrogenating, fluorinating, halogenating, introducing free radicals or benzene rings into the graphene and modifying to obtain a modified graphene, adding epoxy resin E-51, thinner, ground mica iron oxide and ground superfine talcum powder to a high-speed stirrer, stirring and mixing well to obtain a mixed slurry for later use, adding floating aluminum powder slurry and precipitated barium sulfate to the mixed slurry and stirring with a high-speed stirrer to obtain a paint, adding the modified graphene, the dispersant and the paint to a high-speed disperser and dispersing at a speed of 1200 rpm, so that the modified graphene can be uniformly dispersed in the paint to obtain an anticorrosive paint, and packaging the anticorrosive paint according to the specifications. USE - Preparation of graphene-based anticorrosive paint. ADVANTAGE - The graphene-based anticorrosive paint is hydrophobic. By modifying graphene, the solubility, dispersibility and compatibility of graphene inorganic nanofillers in the coating matrix are effectively improved, while maintaining its performance, and without destroying the conjugated structure of graphene. By adding modified graphene to the paint, the graphene can be completely dispersed in the paint, enhance the overall performance of the paint, make the paint highly anticorrosive and make the paint work better.
