Automotive upholstery dual-UV-curing coating, preparation method thereof and coating film formed by the coating

The invention discloses automotive upholstery dual-UV-curing coating, a preparation method thereof and a coating film formed by the coating. The coating is prepared from the following raw materials inparts by weight: tetrafunctional aliphatic polyurethane acrylic resin, six-functional-group aliphatic polyurethane acrylic resin, two-functional-group aliphatic polyurethane acrylic resin, epoxy acrylic resin, an ultraviolet light initiator 184, an ultraviolet light initiator TPO, a leveling agent, ethyl acetate and butyl acetate. The coating has the advantages that the performance is excellent,a coating layer can be completely cured and cross-linked, solvent residue and after-tack are avoided, the dispersibility is good during spraying, the leveling property is moderate, the thixotropy is moderate, and the coating layer is uniform, free of obvious orange peel, free of needle holes and bubbles and free of impurity points. The coating surface is full in leveling, good in glossiness, goodin smoothness and relativel
