NOVELTY - An epoxy corrosion-resistant waterproof coating comprises (A) component and (B) component. The (A) component comprises 25-30 pts. wt. epoxy resin, 12-14 pts. wt. modified polyurethane, 4-8 pts. wt. zinc oxide, 3-6 pts. wt. nano-silicon dioxide, 8-10 pts. wt. ethyl acetate, 2-3 pts. wt. nano-molybdenum disulfide, 2-4 pts. wt. graphene oxide, 2-6 pts. wt. sodium lignosulfonate, and 2-3 pts. wt. barium titanate. The (B) component comprises 12-24 pts. wt. active diluent, 2-6 pts. wt. curing agent, 2-3 pts. wt. cross-linking agent, and 1-4 pts. wt. plasticizer. USE - Epoxy corrosion-resistant waterproof coating. ADVANTAGE - The anti-corrosion performance of the coating is effectively improved. The hydrophobicity of the coating after the coating is used is improved. The waterproof effect of the coating is improved. The adhesion of the coating is ensured to prevent the coating from cracking and falling off. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of epoxy corrosion-resistant waterproof coating, which involves (1) adding graphene oxide to distilled water, after raising the temperature to 60?oC, adding sodium lignosulfonate, mixing and stirring uniformly, ultrasonically dispersing for 10-15 minutes, placing in a stirred tank, mechanically stirring at high speed, and vacuum drying in a vacuum drying box to obtain modified graphene oxide, (2) adding the modified graphene oxide to distilled water, adjusting pH to acidic, adding zinc oxide, putting in 80?oC water bath, ultrasonically homogenizing, taking out for high speed centrifugation, putting the centrifugal precipitate in a hot air drying box, drying to obtain dry precipitate, adding epoxy resin, heating at 50-60?oC after magnetic stirring for 2 hours, putting in a high-pressure reactor, and high-pressure stirring for 20-30 minutes to obtain composite epoxy resin, (3) adding nano-silicon dioxide to ethyl acetate, fully stirring, adding modified polyurethane, putting in high pressure reactor in the atmosphere of nitrogen, high-pressure mixing and stirring for 30 minutes to obtain composite material, (4) adding the composite epoxy resin to nano-molybdenum disulfide, mixing barium titanate in high temperature water bath environment, stirring uniformly, continuously stirring for 20-30 minutes in a low temperature environment, taking out, recovering to normal temperature, and adding composite material, heating at 60-80?oC, and stirring uniformly to obtain (A) component, and (5) mixing active diluent, curing agent, crosslinking agent, and plasticizer in high temperature environment, mechanically stirring uniformly, and cooling to normal temperature to obtain (B) component.
