High-adhesion UV (ultraviolet) coating on PET (polyethylene terephthalate) film, preparation method of high-adhesion UV coating and preparation method of film material

The invention relates to the technical field of coatings, in particular to a high-adhesion 3D transfer printing UV coating on a PET film and a preparation method of a film material of the high-adhesion 3D transfer printing UV coating. The water-based paint is prepared from the following components in parts by weight: 10 to 50 parts of epoxy modified acrylate, 10 to 50 parts of modified epoxy acrylate, 0 to 20 parts of polyurethane acrylate, 0 to 20 parts of reactive diluent, 0 to 0.5 part of defoaming agent, 0.2 to 10 parts of initiator, 0 to 10 parts of filler, 0.1 to 0.5 part of flatting agent and 8 to 20 parts of reactive diluent. The components are mixed or prepared into the coating, and the epoxy modified acrylate, the modified epoxy acrylate and the reactive diluent are selected, so that the prepared coating has remarkably higher adhesive force, strength and toughness on a PET (Polyethylene Terephthalate) film. 本发明涉及涂料技术领域，尤其涉及一种PET膜上高附着的3D转印UV涂料及其膜材制备方法。其包括以下重量份的组分：环氧类改性丙烯酸酯10-50份、改性环氧丙烯酸酯10-50份、聚氨酯类丙烯
