▎ 摘  要

NOVELTY - The preparation method of graphene oxide-modified aqueous acrylic anticorrosive coating involves (1) mixing N,N-dimethylformamide, graphene oxide, catalyst and glycidyl neodecanoate, reacting at 120-150 degrees C, cooling and centrifuging to obtain solid phase, and vacuum drying to obtain modified graphene oxide, (2) adding modified graphene oxide, film-forming aid, hydroxy acrylic emulsion and defoaming agent to a three-roller grinder, grinding, adding Cymel 325 (RTM: Methylated high imino melamine crosslinker) amino resin, and grinding. USE - Preparation method of graphene oxide-modified aqueous acrylic anticorrosive coating. ADVANTAGE - The method enables preparation of graphene oxide-modified aqueous acrylic anticorrosive coating with excellent coating ability, reduces the Van der Waals force between graphene oxide sheets by modifying the surface of graphene oxide, introduces long alkyl chains, and improves the dispersion stability of graphene oxide.
