Abstract: AGO/WEP and KGO/WEP anti-corrosion coating was prepared, using epoxy resin E-44 and three acrylic monomers as raw materials, modified by different dosages of graphene oxide (KH560/GO (KGO), A151/GO (AGO)) under in-situ polymerization method. The results show that the addition of KGO or AGO can both improve the thermal performance of the composite coating. The comprehensive performance of 0.05wt%KGO/WEP is better, the pencil hardness of the composite coating is 5H, the impact strength is more than 50 cm, the bonding strength is 1.79 MPa, the water absorption rate is 1.06%, the contact angle is 78.05°, the color difference after 1000 h UV aging is 0.75, the gloss is maintained well at 9.7, the coating morphology is maintained well after 240 h of chemical resistance, and the chloride ion permeability of the coating is 0.34×10⁻³ mg/(cm²·d). The results show that the 0.05wt%KGO/WEP coating has good comprehensive performance and a maximum bond strength is 1.91 MPa after 40 salt freeze cycles. The mass growth rate is 1.46%, the chloride ion flux at 6 h is 532 C, the compressive strength loss is 18.2%. The composite coating can effectively improve the corrosion resistance of snow melting salt on the surface of concrete substrate, and has important research significance for improving the maintenance level of roads.
