Graphene-based hydrophobic anticorrosive coating and application thereof

The invention discloses a graphene-based hydrophobic anti-corrosion coating and application thereof. The graphene-based hydrophobic anti-corrosion coating is prepared through the following steps of material selection, mixture preparation, base material preparation, anti-corrosion coating preparation and application of the anti-corrosion coating. Through mechanism research on graphene, graphene oxide subjected to surface modification treatment is selected as a graphene base material added in the coating, an organic silicon dispersant is introduced as a basic dispersant when all components in the heavy anti-corrosion coating are mixed with graphene slurry, 1%-5% of the graphene slurry is added on the basis of an original formula, and the organic silicon dispersant is added on the basis of the original formula. The addition amount of a key anti-rust pigment mica iron oxide in an original formula is reduced, the polarity of a diluent in the original formula is adjusted, the addition amount of epoxy resin is adjus
