The invention provides wear-resistant paint used for metal components, and a preparation method of the wear-resistant paint. The wear-resistant paint contains the following ingredients in parts by weight: 5-16 parts of cellulose acetate, 15-31 parts of epoxy phenolic resin, 5-12 parts of trimethylolpropane triacrylate, 1-3.6 parts of chlorinated polyethylene, 0.5-1.3 parts of tetraethyl orthosilicate, 2-5 parts of glycol dimethacrylate, 20-35 parts of diethylenetriamine, 12-25 parts of ethylenediamine, 0.3-0.6 parts of antiager, and 0.1-0.3 parts of benzophenone. The paint provided by the invention has good wear resistance, scratch resistance and gloss, and also has good ageing resistance, so as to well protect metal components.
