NOVELTY - Graphene anticorrosive coating comprises component-A and component-B in the mass ratio of 5-20:1; the component-A comprises 5-20 wt.% epoxy resin, 1-5 wt.% coupling agent, 2-15 wt.% rheological auxiliary agent, 1-15 wt.% graphene resin slurry, 10-55 wt.% zinc powder, 15-32 wt.% filler, and 5-25 wt.% mixed solvent; where the graphene resin slurry composed of 30-50 wt.% epoxy resin, 1-5 wt.% rheological auxiliary agent, 35-45 wt.% mixed solvent, 1-15 wt.% graphene and 5-10 wt.% dispersing agent; the component-B comprises 25-40 wt.% curing agent, and 60-75 wt.% mixed solvent. USE - The anticorrosive coating is useful for transformer shell (claimed). ADVANTAGE - The anticorrosive coating: has high strength, good toughness, strong adhesion, low zinc content, and good corrosion resistance; and can prolongs the service life of the transformer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene anticorrosive coating comprising (1) mixing epoxy resin, rheological auxiliary agent and mixed solvent evenly, carrying infiltration treatment on graphene; after infiltration treatment, dropwise adding the dispersing agent while stirring, stirring at high speed for 35 minutes, carrying ultrasonic dispersion for 20 minutes, finally grinding with three-roller to obtain stable graphene resin slurry; mixing epoxy resin, auxiliary agent, large amount of mixed solvent, graphene resin slurry, and coupling agent, stirring at high speed for 30 minutes, adding zinc powder, filler, and remaining mixed solvent, under the condition of speed 1500-3000 revolutions/minute and temperature of less than or equal to 50 degrees C, dispersing, grinding, and stirring until the fineness is less than 40 mu m, and filtering to obtain the component-A in the coating; where the amount of the large amount of mixed solvent is not less than 70% of the total amount of mixed solvent; (2) dissolving the curing agent with mixed solvent evenly at temperature not exceeding 50 degrees C, dispersing for 30 minutes to obtain the component-B in the coating; and (3) mixing and stirring the component-A and component-B according to predetermined ratio.
