The invention relates to a corrosion-resistant elevator color-coated sheet. The corrosion-resistant elevator color-coated sheet is sequentially provided with a surface coating, a bottom coating, a passivation layer and a base sheet layer from top to bottom. The surface coating comprises, by weight, 100 parts of epoxy resin, 20-22 parts of acetylene-butyl acrylate copolymer, 5-6 parts of octyl benzoate and 5-6 parts of n-methylacetamide. The bottom coating comprises, by weight, 100 parts of polyurethane resin, 9-10 parts of borax, 4-5 parts of sodium silicate, 10-12 parts of propylene-styrol copolymer, 2-3 parts of gamma-lactam and 2-3 parts of hexamethyl-disilazane. According to the scheme, a traditional elevator color-coated sheet is modified, and various modifying materials are introduced to improve the structure toughness, the surface strength, the corrosion resistance and the scratch resistance of the coatings.
