▎ 摘　　要

NOVELTY - A graphene-basalt composition is prepared by adding graphene to water, uniformly mixing, heating, adding p-phenylenediamine, uniformly mixing, leaving still, filtering, washing the solid substance, and drying. USE - The graphene-basalt composition is useful for preparing coating (all claimed) for petrochemical industry, construction industry, transportation industry, ocean engineering, port engineering and bridge steel structure. ADVANTAGE - The graphene-basalt composition provides coating, which has improved corrosion resistance through synergistic effect of the raw materials. Graphene has high mechanical strength, compact structure, large specific surface area and improved mechanical performance and rust-proof performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a coating, which is added with 1.06-3.11 wt.% graphene-basalt composition; and preparation of the coating, which involves mixing epoxy-modified hydroxyacrylic acid resin, defoamer (a,b), anti-aging agent, adhesion promoter, thixotropic agent, solvent, modified basalt, and pigment to obtain component (A), evenly mixing isocyanate curing agent and aliphatic polyamine curing agent to obtain component (B), and uniformly mixing components (A,B) and the graphene-basalt composition.
