Water-based anticorrosive coating and preparation method thereof

[0076] The embodiments of the present invention provide a water-based anti-corrosion coating and a preparation method thereof. The conductive polymer / fullerene composite modified water-based anti-corrosion coating is prepared by stirring and mixing components A and B uniformly; the component A Including the following components: water-based isocyanate curing agent, zinc powder, defoamer, wetting and dispersing agent, anti-sedimentation thixotropic agent, conductive polymer / fullerene composite material, anti-flash rust agent, leveling agent, adhesion promotion agent, anti-rust pigment.

[0077] Preferably, the curing agent is at least one of water-based isocyanate curing agents BA305, XP2451, and XP 2487. BA305 is a crosslinking agent for water-based coatings. Even under pre-diluted conditions, the coating film is still transparent and bright; XP 2451 and XP 2487 is used as a curing agent component of water-based two-component coatings and sealers, and also as an additive to en...

[0090] In terms of parts by mass, the raw material formula of component A consists of: 15 parts of BA305, 55 parts of 400 mesh zinc powder, 5 parts of EL-2607, 5 parts of SN-5040, 2 parts of organic bentonite, 2 parts of conductive polymer / fullerene parts, ZT-709 0.5 parts, SN-612 0.5 parts, kh560 3 parts, zinc phosphate 10 parts. The raw material formula of component B is composed of: 6 parts of methyl methacrylate, 20 parts of butyl acrylate, 16 parts of styrene, 15 parts of epoxy resin, 1 part of methacrylic acid, 1 part of acrylamide, and 1.5 parts of hydroxyethyl acrylate , 1.5 parts of emulsifier, 4 parts of initiator, 120 parts of deionized water, 0.4 part of ammonia water.
