Abstract
The invention provides an anti-corrosion water-based epoxy paint, which comprises following raw materials in parts by weight: 63-65 parts of fluid epoxy resin, 6-8 parts of flexibilizer, 47.8-52 parts of pigment, 2.0-3.0 parts of corrosion inhibitor, 20.0-25.0 parts of anti-rust pigment, 60-80 parts of polyamide-polyamine water solution, and 52.4-60 parts of water, wherein the mass percent of the polyamide-polyamine water solution is 45%-55%. According to the preparation method, the fluid epoxy resin, flexibilizer, pigment, corrosion inhibitor, anti-rust pigment and water are uniformly mixed, and then the mixture is mixed with polyamide-polyamine water solution so as to prepare the anti-corrosion water-based epoxy paint. The epoxy resin with functional groups is added into the polyamide-polyamine copolymer, so that the crosslinking density of the paint is effectively and greatly improved, the gloss of the film is improved, and the resistance to chemicals, especially alkali is improved; the impact strength can reach 65cm, the toughness is 2mm, and the paint resists 8% HCl and does not change 120 hours later.
