▎ 摘　　要

NOVELTY - Graphene-modified heavy-duty anti-corrosion coating comprises 20-50 %mass resin, 20-80%mass pigments and fillers, 1-20 %mass graphene dispersion slurry, 2-10 %mass additives and 5-20 %mass solvent. USE - As graphene-modified heavy-duty anti-corrosion coating. ADVANTAGE - The graphene-modified heavy-duty anti-corrosion coating has an excellent dispersion uniformity, stability, water resistance and salt spray resistance, improves the overall anti-corrosion efficiency of the coating, reduces the zinc content, is environmentally-friendly and cost-effective, and reduces the emission of organic volatiles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene modified heavy-duty anti-corrosion coatings, comprising (a) putting the resin in the solvent and mixing once to obtain a resin slurry, (b) placing the graphene and the dispersant in a dispersion medium for secondary mixing to obtain a graphene dispersion slurry, and (c) adding pigments and fillers, additives and the graphene dispersion slurry to the resin slurry and mixing three times.
