Problems solved by technology

However, the water-based UV coating prepared in this patent needs to add solvents such as film-forming aids propylene glycol butyl ether, which causes certain environmental pollution; for the materials used in conventional mobile phones, computers, and home appliances, PET (polyethylene terephthalate) ), PC (polycarbonate), PMMA (polymethyl methacrylate) are crystalline or semi-crystalline polymer materials. Difficult to volatilize in the process, low production efficiency

Abstract

The invention provides a flexible and stain-resistant ultraviolet curable coating composition. The composition comprises, by weight, 30-80 parts of acrylate resin, 5-15 parts of a fluorine-modified acrylate oligomer, 10-25 parts of an acrylate monomer, 5-9 parts of a photoinitiator and 0.05-2 parts of a leveling agent. Compared with coatings in the prior art, the coating composition in the invention has a higher flexibility, and has the advantages of certain hardness, wear resistance, stain resistance, suitableness for bendable and crimped substrates, excellent comprehensive performances and wide applicability .

Description

technical field [0001] The invention relates to the field of ultraviolet light curing coatings, in particular to a flexible and antifouling ultraviolet light curing coating composition and a preparation method thereof. Background technique [0002] UV-curable coatings are developing rapidly. Because the cured coatings have excellent scratch resistance, high hardness, and good fullness, and because of their advantages such as high efficiency, energy saving, environmental protection, and economy, they are currently used in construction, sporting goods, It is widely used in electronic communication, packaging materials and auto parts. However, conventional UV-curable coatings blindly pursue high hardness and high scratch resistance. During use, there are bending cracks, cracks, and even breaks, and they are easily polluted by fingerprints and skin oils, which seriously affects the product. The use of the product, as well as the aesthetics, protection and other related performa...
