One-coat colored UV (ultraviolet) coating with imitation metal effect and preparation method of one-coat colored UV coating

The invention belongs to the technical field of coatings, and particularly relates to a one-coat colored UV coating with a metal imitation effect. The UV-curable coating comprises the following raw materials in parts by weight: 20-40 parts of UV-curable resin, 5-10 parts of thermoplastic acrylic resin, 5-10 parts of an active monomer, 5-15 parts of silicon dioxide aerogel particles, 20-30 parts of ethyl acetate, 14-30 parts of butyl acetate, 5-10 parts of silver paste, 0.2-1 part of a wetting dispersant and 1-4 parts of a photoinitiator. The invention also discloses a preparation method. The coating prepared in the invention not only has an excellent metal-imitating effect, but also has the effects of heat preservation, heat insulation and muting, is simple in preparation process, low in energy consumption, environment-friendly, high in product yield and low in production cost, has the characteristics of good wear resistance and good chemical resistance, has good binding power to various plastic substrates, a
