Abstract

The invention provides a UV-cured water-based vacuum sputtering coating, which is characterized by comprising the following components in parts by weight: 35-47 parts of an oligomer; 3-5 parts of a monomer; 40-50 parts of pure water; 3-5 parts of an auxiliary functional base; 2-4 parts of a photo initiator; 2-5 parts of an auxiliary agent; and 1-3 parts of tea polyphenol. The water-based UV coating prepared by the invention has the characteristics of high curing speed, excellent adhesive force, good heat resistance and good plating property, has good adaptability in the field of vacuum coating, can effectively solve the problem of poor adhesive force of a water-based PVD coating, and can also solve the problem of poor selectivity of sputtered metal.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a UV-cured water-based vacuum sputtering coating. Background technique [0002] UV curing is under the irradiation of high-energy UV light, the photoinitiator absorbs UV light to generate active free radicals, triggers UV oligomers and active diluent molecules to undergo a chain polymerization reaction, and makes the liquid phase system polymerized, cross-linked and cured with high efficiency and energy saving This environmentally friendly new technology has the advantages of fast curing speed, low energy consumption, safety and environmental protection, and is widely used in various fields. As the country pays more and more attention to energy saving, emission reduction and environmental protection, people's demand for UV curing products is also increasing. For this reason, UV coatings are water-based, which not only combines the characteristics of safety and environmental pr...
