▎ 摘　　要

NOVELTY - Producing graphene-based coating agent, comprises (a) producing coating agent comprising 2-10 wt.% n-tetrabutyl titanate, 0.01-0.1 wt.% graphene derivatives, 0.1-1 wt.% aluminum sulfate, 0.01-0.1 wt.% surfactant, water and isopropyl alcohol, (b) applying the coating agent on surface of the base material by spraying, dip coating, and brush coating method, (c) drying the coating on the surface of the base material at 350-400 degrees C. The graphene derivative has particle size distribution (D10-D90) of 1-100 mu m, and average thickness of 1-100 nm. The surfactant includes sodium dodecylsulfonate and/or alkylphenol ethoxylate. USE - The coating agent is useful for building structural materials, ship yacht, marine monitoring equipment, new energy vehicles and aerospace vehicles. ADVANTAGE - The coating agent has excellent corrosion resistance and antifouling, and is environmentally friendly.
