▎ 摘　　要

NOVELTY - Modified graphene oxide epoxy resin composite coating comprises 1-4 pts. wt. cerium oxide, 4-15 pts. wt. salt iron solution, 80-90 pts. wt. epoxy resin and 1-2 pts. wt. graphene oxide. USE - Modified graphene oxide epoxy resin composite coating. ADVANTAGE - The modified graphene oxide epoxy resin composite coating has easy availability of raw materials, reasonable process route and convenient operation, no pollution in the preparation process, and good anticorrosive performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing modified graphene oxide epoxy resin composite coating, which involves: (A) adding the grapheneoxide dispersion liquid and cerium(III) nitrate hexahydrate into the distilled water; (B) adjusting pH to 11-12; (C) performing hydrothermal reaction to obtain the graphene oxide composite modified by nanocerium oxide particles; (D) adding the nano ceriumoxide particle modified graphene oxide composite into the inorganic salt iron solution; (E) carrying out hydrothermal reaction; (F) drying and calcining under the inert gas condition to obtain the modified graphene oxide composite material; and (G) mixing the modified graphene oxide composite material with vinyl resin uniformly to obtain the composite coating.
