The invention relates to the field of coatings and specifically relates to an oil paint for ships and a production method thereof. The oil paint for ships comprises the following raw materials in parts by weight: 80-120 parts of epoxy resin, 50-70 parts of acrylic resin, 20-30 parts of titanium dioxide, 15-20 parts of nanometer iron oxide, 15-20 parts of nanometer titanium oxide, 18-20 parts of barite, 5-10 parts of modified hydrogenated castor oil, 3-5 parts of perlite, 2-3 parts of de-foaming agent, 1-1.5 parts of dispersing agent, 0.8-1 part of anti-settling agent and 0.5-1 part of thickening agent. The prepared oil paint for ships is capable of avoiding seawater corrosion and atmospheric corrosion and has high hardness, high resistance to corrosion, stable use effect, excellent water and oil repellent, antifouling property and corrosion resistance; the oil paint is unlike to attach to the marine organisms, and thus is harmless to the marine organisms and is suitable for the operating environment of ships; the oil paint is capable of resisting against seawater impact, is unlike to blister and fall off after long-term soaking in water and has excellent corrosion resistance; the antifouling and rustproof effects are excellent.
