▎ 摘　　要

NOVELTY - A coating material comprises benzoic acid-functionalized graphene, aqueous epoxy resin, aqueous curing agent and water. The benzoic acid-functionalized graphene is prepared by processing graphene with para-aminobenzoic acid. USE - Coating material is used for steel structural component. ADVANTAGE - The coating material has excellent flame retardance and corrosion resistance, and can be prepared with reduced energy consumption and usage amount of filler, by environmentally-friendly process. The filler has excellent compatibility with aqueous epoxy resin, thereby increasing the crosslinking density and thermal-barrier property of the epoxy resin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of coating material.
