▎ 摘　　要

NOVELTY - Preparing marine anti-corrosion coating, comprises (a) oxidizing substrate, (b) forming a coupling layer on the substrate using an aminosilane coupling agent, where the aminosilane coupling agent is gamma -aminopropyl (methyl)diethoxysilane, gamma -aminopropyl (methyl)dimethoxysilane, gamma -aminopropyl trimethoxysilane, gamma -aminopropyl triethoxysilane, N-( beta -aminoethyl)- gamma -aminopropyl trimethoxysilane and/or gamma -diethylenetriaminepropyl methyl dimethoxysilane, and (c) spraying graphene oxide on the substrate to form a film, and then drying. USE - The method is useful for preparing marine anti-corrosion coating (claimed). ADVANTAGE - The method: improves adhesion between coating and the substrate; and ensures enhanced service life of the coating.
