The invention discloses an environment-friendly waterproof corrosion-resistant marine coating. The environment-friendly waterproof corrosion-resistant marine coating consists of the following materials in parts by weight: 30 to 40 parts of polyvinyl acetal-modified phenolic resin, 10 to 15 parts of poly(ethyl acrylate) emulsion, 20 to 30 parts of organic silicon-modified polyester resin, 10 to 15 parts of isophthalic unsaturated polyester resin, 3 to 13 parts of lead chromate, 3 to 12 parts of hydroxypropyl methylcellulose, 2 to 6 parts of sodium carboxymethylcellulose, 1 to 5 parts of hydroquinone, 5 to 15 parts of aluminium nanopowder, 10 to 15 parts of modified mica, 10 to 15 parts of aluminium hydroxide, 15 to 20 parts of nano calcium oxide, 5 to 10 parts of zinc oxide, 2 to 4 parts of chromium phosphate, 1 to 3 parts of barium phosphate, 5 to 10 parts of calcium phosphate, 1 to 3 parts of iron oxide red and 2 to 5 parts of phthalocyanine blue. The waterproofness of the environment-friendly waterproof corrosion-resistant marine coating is good, the corrosion resistance of the environment-friendly waterproof corrosion-resistant marine coating is excellent, and moreover, the environment-friendly waterproof corrosion-resistant marine coating does not pollute the environment.
