▎ 摘  要

NOVELTY - Graphene-type single-component cold-coated aluminum anticorrosive coating comprises 15-30 wt.% methoxysilane resin, 0.1-1 wt.% rheological agent, 0.1-3 wt.% organic-functional silane, 30-40 wt.% aluminum powder pigment, 40-50 wt.% flaky alumina, 0.5-1.5 wt.% organic titanate, 10-30 wt.% diluent and 0.1-3 wt.% graphene. USE - Graphene-type single-component cold-coated aluminum anticorrosive coating (claimed). ADVANTAGE - The coating film forming time is shortened and the requirements of the substrate are reduced. The method simplifies the construction steps and improves the construction efficiency. The perfect lattice structure of graphene improves the adhesion, anti-scratch property and flexibility of the coating. The high solid content of aluminum powder pigment and the flaky structure of alumina enhance the tightness of the coating, and thus the corrosion resistance of the coating is improved. The cold-coated aluminum coating has super-hydrophobic and super-oleophobic properties. The coating does not change its performance under the high temperature conditions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing graphene-type single-component cold-coated aluminum anticorrosive coating, which involves adding methoxysilane resin, diluent and rheological agent in a container, stirring at a speed of 600 rpm for 30 minutes, (ii) adding organic titanate and organic-functional silane to the mixed solution when the material is mixed evenly, stirring at a speed of 800 rpm for 45 minutes, (iii) finally adding graphene, aluminum powder pigments and flaky alumina, stirring at a speed of 800 rpm until all the materials are mixed evenly, increasing the speed to 3000 rpm, and performing high-speed dispersion until the fineness reaches 60 mu m.
