NOVELTY - A modified heavy anti-corrosion coating comprises 25-32 wt.%, preferably 29 wt.% epoxy resin, 8-12 wt.%, preferably 10 wt.% butane tetracarboxylic acid, 7-10 wt.%, preferably 8 wt.% methylene succinic acid, 4-10 wt.%, preferably 6 wt.% N-vinylpyrrolidone, 4-8 wt.%, preferably 7wt.% graphene, 3-7 wt.%, preferably 5 wt.% 5-sulfosalicylic acid and remaining solvents. USE - Modified heavy anti-corrosive coating used for construction in marine environment. ADVANTAGE - The construction efficiency is improved. The raw material components are simple. The preparation process of coating is simplified, and the production is facilitated. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of modified heavy anticorrosive coating containing graphene, involves (1) dividing the solvent into solvent (I) and solvent (II), (2) mixing epoxy resin, solvent (I), graphene, butane tetracarboxylic acid and N-vinyl pyrrolidone, putting into the reaction kettle, and performing vacuum mixing reaction at 115-155 degrees C for 25-40 minutes, (3) adding methylene succinic acid and 5-sulfosalicylic acid to stirring vessel, adding solvent (II), stirring under vacuum, and uniformly mixing, (4) mixing the obtained product, vacuum stirring and reacting at 120-140 degrees C for 20-30 minutes.
