▎ 摘　　要

NOVELTY - Preparation method of modified graphene coating material involves performing preparation of graphene, raw material ratio, and mixing processing using 25-50 wt.% modified resin, 5-20 wt.% graphene, 1-3 wt.% graphene-dispersant, 1-1.5 wt.% nano-titanium powder, 1-1.5 wt.% dispersant, 30-40 wt.% solvent and 0.5-1.5 wt.% catalyst. USE - Preparation method of modified graphene coating material. ADVANTAGE - The method uses the graphene containing richer oxygen-containing functional groups and is easy to modify for reaction mixing, and promotes the full mixing in the solvent by the effective adsorption of graphene oxide with excellent adsorption property and high stability. The coating material does not fall off and degenerate for a long time.
