The graphene-modified styrene-acrylic-epoxy emulsion protective coating was prepared by physical blending method with waterborne epoxy emulsion, Kaolin, self-made rust transfer agent and graphene oxide dispersion as the modified materials of styrene-acrylic emulsion. The effects of styrene-acrylic-epoxy emulsion ratio and content of Kaolin, rust transfer agent and graphene oxide dispersion on the bonding strength of the coating were discussed, and the tensile properties and basic properties of the coating were investigated. The results show that the bond strength of the coating increases with the increase of the mass ratio of waterborne epoxy emulsion and increases first and then decreases with the increase of the content of Kaolin,rust transfer agent and graphene dispersion. When mphenyl acrylic: Qepoly =1:2 and content of Kaolin,rust transfer,graphene oxide dispersion is 10,3,0. 2,respectively,coating basic performance is good,and the coating resistivity is much larger than ordinary metal materials,exceUent protective effect.
