The invention discloses a corrosion-resistant coating for a marine ship. The corrosion-resistant coating is prepared from the following raw materials in parts by weight: 5-10 parts of styrene-acrylic emulsion, 20-30 parts of epoxy resin, 40-50 parts of an organic solvent, 15-20 parts of an interface regulator, 10-20 parts of a nano silicon dioxide coordinated glass fiber modifier, 10-15 parts of ammonium polyphosphate, 2-4 parts of a curing agent and 1-3 parts of a wetting agent. According to the corrosion-resistant coating disclosed by the invention, the styrene-acrylic emulsion and the epoxy resin are adopted as matrixes, the flame-retardant property of a product is optimized by adding the ammonium polyphosphate flame retardant, and the flame-retardant, fireproof and antifouling coordination of a synergistic product is optimized by coordinating the interface regulator and the nano silicon dioxide with the glass fiber modifier; and meanwhile, the corrosion resistance of the product is further improved. 本发明公开
