NOVELTY - Preparing graphene zinc-loaded powder, involves (a) mixing natural crystalline flake graphite, potassium permanganate and concentrated sulfuric acid, stirring at normal temperature for 2-3 hours, stirring at 40-50℃ for reaction for 0.5-2 hours, adding sufficient water, adding excessive hydrogen peroxide to stop the reaction, and then carrying out suction filtration and washing to neutrality to obtain a graphite oxide filter cake, (b) dispersing the graphite oxide filter cake in deionized water, adding a surfactant and nano zinc oxide, performing ultrasonic dispersion uniformly, and performing spray drying on the obtained mixed solution to obtain mixed powder of graphite oxide and nano zinc oxide, and (c) adding carbon into the mixed powder of graphite oxide and nano zinc oxide, then placing the mixed powder into a tubular furnace, and carrying out high-temperature reduction reaction in an argon/hydrogen mixed gas environment to obtain the graphene zinc-loaded powder. USE - Method for preparing graphene zinc-loaded powder. ADVANTAGE - The modified graphene anticorrosive paint effectively improves conductivity between zinc and steel and between zinc particles, has a compact coating and a prolonged corrosion route, reduces the zinc consumption and the coating thickness in a unit area, improves the shock resistance and the corrosion resistance of the coating, and has certain heat dissipation performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: A graphene zinc-loaded powder prepared by the preparation method. An anticorrosive paint, comprises graphene-supported zinc powder, and is prepared by uniformly stirring and grinding the graphene zinc-loaded powder, the filler, the deionized water and the first auxiliary agent to obtain anticorrosive slurry, and fully mixing the anticorrosive slurry with a binder and a second auxiliary agent to obtain the anticorrosive paint containing the graphene zinc-loaded powder.
