The coating is prepared from the following components in parts by weight: 10 to 13 parts of trifunctional acrylate monomer, 2 to 5 parts of monofunctional acrylate monomer, 1 to 3 parts of phosphate, 2 to 5 parts of 1-hydroxycyclohexyl phenyl ketone, 0.5 to 2 parts of benzoin dimethyl ether, 0.1 to 0.3 part of flatting agent, 20 to 30 parts of ethyl acetate, 10 to 20 parts of butyl acetate and 5 to 10 parts of propylene glycol methyl ether acetate. The epoxy acrylate oligomer, the aliphatic polyurethane acrylate and the polyester acrylate which are high in performance and mature in process are mainly selected as main film forming substances and are good in miscibility, a cured paint film is high in compactness and good in developability, and a trifunctional acrylate monomer is matched and is high in reactivity, so that the film forming effect is good. The high crosslinking density ensures that a paint film has enough brightness and fullness so as to ensure the physical and chemical properties of a product, and meanwhile, the constructability such as a leveling effect is improved.
