The invention discloses anti-corrosive paint for steel materials of ships and a preparation method of the anti-corrosive paint. The anti-corrosive paint comprises the following raw materials by weight: 25 to 30 parts of a polyester emulsion, 8 to 10 parts of carboxyl butadiene-arylonitrile rubber, 6 to 8 parts of polyvinyl alcohol, 2 to 3 parts of a silane coupling agent KH570, 12 to 15 parts of a styrene-acrylic emulsion, 1.2 to 1.5 parts of quartz sand, 0.3 to 0.5 part of methyl-ethyl ketone curing agent, 2 to 4 parts of polyepoxysuccinic acid, 1.5 to 1.8 parts of a cobalt iso-octoate accelerating agent, 3 to 5 parts of preservative, 5 to 7 parts of caprolactam, 0.8 to 1.2 parts of a penetrating agent, and 7 to 9 parts of poly-amide fiber. The anti-corrosive paint has the advantages that the sediment generation possibilities in the preparation process and a use process are low; the steel materials can be provided from corrosion effectively; the spray coating index of the anti-corrosive paint on the surfaces of the steel materials is high; the permeation and the adhesive strength are high; the welding resistance coefficient is 90 percent or higher; the wear resistance and the anti-scuffing property are good; the surface hardness of a co-diffusion layer is equal to or larger than 330 Hv; the corrosion resistance is high; steel adopting the paint can exist 720 hours or longer without red rust in a neutral salt mist test; the anti-corrosive paint is suitable for surface treatment of general steel products, convenient and practical to use, and suitable for popularization and application.
