NOVELTY - Aqueous-based coating comprises component A and B at a mass ratio of 1:5-50, where the component A comprises 0.05-5.5 pts. wt. polydopamine modified polyaniline/graphene composition and 1-10 pts. wt. deionized water, and the component B comprises 20-35 pts. wt. water-soluble alkyd resin, 5-15 pts. wt. copolymer multifunctional compound, 15-25 pts. wt. resin B, 5-10 pts. wt. pigment, and 1-5 pts. wt. defoamer. USE - Used as aqueous-based coating. ADVANTAGE - The coating is environment-friendly, has high-efficiency and anticorrosion, is a harsh and complex environment; ensures the interaction of heavy and corrosive environments, namely salt spray, damps heat and high in ultraviolet light in coastal wet and dry, which has have a impact on the performance and structural integrity of the sea immersed materials; has simple preparation process, low cost and high repeatability, and improves the service life of the coated steel, has low VOC content, small odor, safe and convenient to use, , excellent corrosion resistance and chemical resistance of the coating, small shrinkage, good hydrophobicity and high hardness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for synthesizing the aqueous-based coating, comprising uniformly mixing the coating from a component of A and B in a ratio of 1:5-50, taking the component A including 0.05-5.5 pts. wt. polydopamine-modified polyaniline/graphene complex by weight, 1-10 pts. wt. deionized water, and component B including 20-35 pts. wt. water-soluble alkyd resin, 5-15 pts. wt. copolymer polyfunctional compound, 15-25 pts. wt. resin B, 5-10 pts. wt. pigments, and 1-5 pts. wt. defoamer.
