▎ 摘　　要

NOVELTY - Preparation of an anticorrosion coating involves (1) dispersing graphite and modifying agent in water to prepare pretreated graphite dispersion, (2) peeling off and modifying the pretreated graphite dispersion obtained in step (1), and preparing modified graphene dispersion, and (3a) mixing the modified graphene dispersion obtained in step (2) with epoxy resin and cationic photoinitiator, separating the phases after standing, and removing the water phase after further deep water removal to obtain graphene/epoxy resin mixture, and curing the obtained mixture. USE - Preparation of anti-corrosion coating (claimed). ADVANTAGE - The method has green preparation technique, excellent product performance and wide application prospect. The method can realize application of modified dispersion graphene in resin by phase transfer method, without drying, graphene can ensure uniform dispersion of the modified graphene in the epoxy resin, at the same time, it can avoid stacking between the modified germanium in the drying process, and better exert excellent performance of modified graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for anticorrosion coating.
