▎ 摘　　要

NOVELTY - A graphene heavy duty, anti-corrosion, environmentally-friendly hard repair coating comprises a component (c1) comprising a polyaspartic acid ester resin, N-carboxymethyl-N-methylpyrrole and a graphene powder, and a component (c2) comprising a hexamethylene diisocyanate (HDI) trimer curing agent. The mass ratio of the component (c1) and the component (c2) is 3:3-4. USE - Graphene heavy duty, anti-corrosion, environmentally-friendly hard repair coating (claimed). ADVANTAGE - The coating is an anti-corrosive, environmentally-friendly and hard repair coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene heavy duty, anti-corrosion, environmentally-friendly hard repair coating, which involves mixing a raw material comprising a polyaspartic acid ester resin, N-carboxymethyl-N-methylpyrrole and a graphene powder to obtain component (c1) and adding HDI trimer curing agent as the component (c2) to the component (c1) to obtain a mixture, and homogeneously stirring the obtained mixture.
