▎ 摘　　要

NOVELTY - A coating comprises 10-23 %mass potassium water glass, 5-18 %mass waterborne epoxy resin, 0.5-2 %mass graphene oxide, 2-10 %mass tin dioxide nanoparticles, 3-12 %mass montmorillonite, 0.2-5 %mass sodium lignosulfonate, 0.6-6 %mass additives and 25-45 %mass distilled water. USE - Coating. ADVANTAGE - The prepared high temperature resistant graphene conductive anticorrosive coating is simple and environmentally-friendly, which can reach level 1, and salt spray resistance is up to 1000 hours due to small size and large surface energy of nanomaterials, the mechanical properties of graphene oxide are improved, the impact resistance of the coating is 50 cm, and the hardness is 6H. The tin dioxide nanoparticles have a low density and are not easy to settle, so that the cured coating has uniform conductivity and the surface resistivity is only 103 Omega . DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacturing of coating, which involves putting graphene oxide and sodium lignosulfonate into distilled water, stirring under speed of 600 rpm for 10 minutes to obtain a graphene oxide dispersion, adding potassium water glass and graphene oxide dispersion liquid to water-based epoxy resin, stirring at 2000 rpm for 20 minutes, mixing montmorillonite and additives, stirring to obtain a mixed liquid, adding tin dioxide nanoparticles to the mixture and stirring.
