3D laser carving high-toughness UV type PVD finish paint

Abstract

The invention relates to 3D laser carving high-toughness UV type PVD finish paint, which is mainly prepared from the following ingredients in parts by weight: 5 to 35 parts of high-functionality urethane acrylate, 5 to 30 parts of thermoplastic acrylate, 1 to 10 parts of reactive diluent, 0.1 to 5.0 parts of photoinitiators, 0.1 to 0.6 part of auxiliary agents and 35 to 80 parts of diluents. The finish paint provided by the invention effectively solves the wide universal problems that the paint adhesion and the toughness of the UV light curing vacuum film plating paint are low, and the matching of the primer of the UV light curing vacuum film plating paint and finish paint in the PU color paint is poor, and the like. The finish paint provided by the invention has a good protection effect and very high flexibility; an obtained paint film has the characteristics of high toughness, high bending performance, excellent annular testing performance and yellowing resistance performance and thelike. Meanwhile, the finish paint has the characteristics that the operation is convenient; the construction is simple; the normal temperature curing is realized; the applicability is wide, and the like. the appearance effect and the service life of the electronic product are effectively improved.

Description

technical field [0001] The invention belongs to the field of chemical coatings, in particular to a 3D radium-carved high-flexibility UV-type PVD topcoat. The topcoat can be used for surface decoration or protection of vacuum coating workpieces of electronic products such as mobile phones, digital cameras, and tablet computers. Background technique [0002] With the development of plastic decoration technology, most of the original plastic products are extrusion or compression molding. During the heating and extrusion process, volatile impurities in the raw materials may escape to the surface, forming more craters, and other microscopic defects. , leading to low surface gloss and poor aesthetics. In addition, most conventional plastic parts are wear-resistant, solvent-resistant, low-performance, easy to scratch, fog, and surface damage. Therefore, it is necessary to decorate the surface of plastic parts and protection. It is formed by using a plastic substrate to coat a pri...
