▎ 摘　　要

NOVELTY - Preparing modified graphene slurry involves mixing the graphene oxide dispersion with the sodium hypophosphite aqueous solution, performing a reduction reaction, separating, washing and drying to obtain graphene. The graphene is added to the nano zinc oxide (ZnO) suspension, ultrasonically dispersed, washed, and dried to obtain ZnO loaded graphene powder. The ZnO loaded graphene powder is placed in a reducing device, and reacted in a reducing atmosphere, and controlled the reaction temperature to be 140-180 degrees C. The reaction time is 1-3 hours to obtain modified supported zinc (Zn) graphene. The modified supported Zn graphene and an organic solvent are mixed for grinding, and then added a dispersant for dispersion to obtain a modified graphene slurry. USE - Method for preparing modified graphene slurry for epoxy anticorrosive primer (claimed). ADVANTAGE - The method enables to prepared modified graphene slurry, where nano zinc-loaded graphene slurry is used in the epoxy anticorrosive primer, so that the salt spray resistance of the epoxy anticorrosive primer is greatly improved, and at the same time amount of zinc powder is greatly reduced, which is suitable for steel structural components with higher requirements for anti-corrosion performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) an epoxy anticorrosive primer is a multi-component epoxy anticorrosive primer, which includes component A and component B, where the component A includes modified graphene slurry, epoxy resin dispersion equipment, zinc powder, inorganic fillers, solvents and other auxiliary, and component B includes polyamide curing agent, xylene, n-butanol and cyclohexanone; and (2) a method for preparing epoxy anticorrosive primer, which involves dispersing the modified graphene slurry and epoxy resin in the dispersion equipment; adding zinc powder, inorganic fillers, solvents and other auxiliary components to the mixed system, continue to dispersing, completing the dispersion, and obtaining component A; and mixing the polyamide curing agent, xylene, n-butanol and cyclohexanone uniformly to obtain component B.
