▎ 摘  要

NOVELTY - Aqueous conductive anticorrosion paint, comprising primer and paint and the finish paint of primer surface layer. The finish paint is made up of A component and B component. The component A includes 40-55 wt.% water-based epoxy resin, 15-28 wt.% conductive hydrogel, 8-15 wt.% first filler, and 1-3 wt.% flame retardant liquid, 0.3-0.8 wt.% water-based dispersant, 0.5-3 wt.% defoamer, 1.5-4 wt.% active monomer, 2-5 wt.% first co-solvent, 0.4-1.2 wt.% amine neutralizer, and 0.2-0.7 wt.% functionalized graphene. The surface of the conductive hydrogel has nano-copper-nickel complex particles with a core-shell structure, the core layer is copper, and the shell layer is nickel. The component B is a water-based epoxy curing agent, and the weight of the B component is 12-28 wt.% of the A component weight. USE - The aqueous conductive anti-corrosive paint is useful in building, mechanical manufacturing, electronic and electrical, aviation, ship transportation, and water conservancy power. ADVANTAGE - The aqueous conductive anti-corrosive paint has excellent corrosion resistance and conductive performance, salt mist resistance of 3000-3000 hours, and paint film surface resistance. The paint has reasonable integral unit price, high stability and excellent conductivity.
