▎ 摘　　要

NOVELTY - Modified graphene oxide material is claimed. The modified graphene oxide is obtained by reacting non-ionic epoxy emulsifier and amino-functionalized graphene oxide. The non-ionic epoxy emulsifier is obtained by polymerizing raw materials containing acrylate monomer and/or methacrylate monomer, allyl polyether and glycidyl methacrylate. USE - The modified graphene oxide material is useful in epoxy resin emulsion for preparing epoxy anti-corrosion coatings (claimed). ADVANTAGE - The modified graphene oxide material: has excellent aqueous properties and strong emulsifying ability; contains epoxy groups, which has excellent compatibility with epoxy resins, thus has improved dispersibility of graphene oxide in epoxy resin. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Preparing modified graphene oxide material, comprising mixing non-ionic epoxy emulsifier with amino functionalized graphene oxide, and reacting to obtain final product; (2) Epoxy resin emulsion, comprising epoxy resin, solvent and modified graphene oxide material; (3) Preparing epoxy resin emulsion, comprising dispersing epoxy resin and the modified graphene oxide material in a solvent to carry out an emulsification reaction to obtain final product.
