The invention relates to a grapheme-modified waterborne anticorrosive coating. The grapheme-modified waterborne anticorrosive coating is composed of a grapheme-modified waterborne alkyd resin, pigment and filler, a cosolvent, a leveling agent, a dispersing agent, a wetting agent, a defoaming agent, a thickening and anti-settling agent, a flash rust inhibitor, a pH value regulator and deionized water, wherein the graphene polyurethane-modified waterborne alkyd resin is prepared from vegetable oil or fatty acid, organic acid anhydride, dimethylolpropionic acid, polyol, grapheme, polyisocyanate and deionized water through a reaction. The prepared grapheme-modified waterborne anticorrosive coating integrates the advantages of grapheme and polyurethane, has properties like high hardness, good adhesion, good chemical resistance, antistatic performance, corrosion resistance, aging resistance and good mechanical properties, and is endowed with excellent corrosion resistance, aging resistance, excellent mechanical properties and antistatic performance.
