▎ 摘　　要

NOVELTY - Graphene oxide slurry, obtained after the mixture of methyl methacrylate, nitrile butadiene rubber and graphene oxide is ball-milled, is claimed. The mixture includes 84-94 wt.% methyl methacrylate, 5-15 wt.% nitrile rubber, and 0.1-1 wt.% graphene oxide. USE - The graphene oxide slurry is used as a filler for an organic anti-corrosion coating (claimed). ADVANTAGE - The graphene oxide slurry has good dispersion stability and high interface compatibility, solves the problem that graphene oxide is easy to agglomerate in a solvent, and can provide a good solution for the subsequent obtaining of high-quality graphene oxide functional coatings. The theoretical basis plays an important role in expanding the application field of materials. In addition, the high-energy ball mill used in the preparation process of the graphene oxide slurry is a conventional general-purpose equipment, with low cost, simple process, easy operation, and easy industrial production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparation of the graphene oxide slurry, comprising (i) mixing methyl methacrylate, nitrile rubber and graphene oxide to obtain compound; (ii) ball-milling the mixture to obtain the graphene oxide slurry; and (2) organic anti-corrosion coating, where the filler in the organic anti-corrosion coating is the graphene oxide slurry.
