The invention discloses an aqueous metal anticorrosive coating, and relates to the technical field of coatings, the aqueous metal anticorrosive coating comprises the following raw materials by weight:70-80 parts of acrylic resin, 10-18 parts of amino resin, 7-15 of aqueous epoxy resin emulsion, 3-7 parts of modified graphene, 2 to 5 parts of attapulgite, 2 to 5 parts of bentonite, 1 to 3 parts ofnano-silica, 2 to 4 parts of potassium titanate whisker, 1 to 3 parts of barium sulfate, 0.5-2 parts of a silane coupling agent, 1-3 parts of dicumyl peroxide, 2-5 parts of polyvinyl alcohol, 0.5-2 parts of sodium dodecyl diphenyl ether disulfonate, 0.5-2 parts of ethyl acetate, 2 to 6 parts of dipropylene glycol monobutyl ether, 0.5 to 2 parts of polyethylene wax, 0.5 to 2 parts of hydroxypropylmethylcellulose, 0.2 to 1 part of a leveling agent, 0.2-1 part of a defoamer, 1-3 parts of an anti flash rust agent and 10-20 parts of deionized water. The aqueous acrylic resin is used as a main film-forming substance, the amino resin and the aqueous epoxy resin emulsion are added for modifying, the modified graphene, the potassium titanate whisker and the like are added, and the obtained coating has excellent water resistance and acid-base corrosion resistance, and can extend the life of a metal.
