▎ 摘　　要

NOVELTY - Anticorrosive coating comprises first component and a second component, where first component includes 0.4-8 wt.% three-dimensional graphene powder, 10-40 wt.% epoxy resin and the remaining first organic solvent, and second component includes 2-5 wt.% reactive diluent, 30-40 wt.% curing agent, and balance is second organic solvent. USE - Anticorrosive coating. ADVANTAGE - The anticorrosive coating stacked in a staggered manner to form a labyrinth shielding structure in the coating, effectively inhibits the infiltration, penetration and diffusion of corrosive media, and improves physical barrier of the coating, fills the defect of the coating, reduces the porosity of the coating, enhances the compactness of the coating, and delays or prevents the corrosion factors from penetrating into the surface of the substrate. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing an anticorrosive coating, which involves mixing a three-dimensional graphene slurry and the epoxy resin to prepare the first component, preparing three-dimensional graphene slurry by mixing the three-dimensional graphene powder with the first organic solvent, preparing second component by mixing the second organic solvent, the reactive diluent and the curing agent, where particle size of the three-dimensional graphene powder is 100-500 nanometer; and (2) a method for using the anticorrosive coating, which involves mixing first component and the second component to prepare the anticorrosive coating, and applying anticorrosive coating to the surface of an object and curing, where mass ratio of the first component and the second component in the anticorrosive coating is 5-15:1.
