The invention relates to oil paint and particularly relates to waterproof wear-resistant polyurethane acrylate oil paint for a copper sculpture. The oil paint is prepared from the following raw materials in parts by weight: 12-15 parts of amino resin, 3-4 parts of boron nitride, 1-2 parts of molybdenum disulfide, 3-4 parts of shell powder, 2-3 parts of citric acid, 1-2 parts of stannous mono-sulphate, 2-3 parts of dicyclopentadiene, 35-40 parts of polyurethane acrylate, 10-12 parts of dipropylene glycol diacrylate, 3-5 parts of allyl glycidyl ether, 1-2 parts of 4-methyl guaiacol, 0.19-0.21 part of an accelerant TT, 5-6 parts of zinc stearate, 4-8 parts of N220 carbon black, 6-9 parts of diamino diphenyl sulfone, 1-2 parts of tributyl tin chloride, 5-6 parts of auxiliaries, 10-12 parts of xylene and 10-12 parts of butyl acetate. The oil paint provided by the invention is strong in adhesive force, bright and full in film, hard and wear-resistant, lasting in color retention, water-permeation-resistant, weatherproof and aging-resistant, long in service life and relatively simple in production process, and can be widely applied to protecting various copper sculpture artware.
