Abstract

The invention provides a UV paint with resistance to yellowing, and its preparation method and construction process. The UV paint comprises, by weight, 5.0 to 15.0% of polyurethane acrylic acid oligomer, l0.0 to 20.0% of aliphatic polyurethane acrylate, 12.0 to 18.0% of trifunctional aliphatic polyurethane acrylate, 3.0 to 6.0% of thermoplastic acrylic resin, 3.0 to 6.0% of trimethylolpropane triacrylate, 2.0 to 4.0% of dipentaerythritol pentaacrylate, 2.0 to 3.0% of 1-hydroxycyclohexyl phenyl methanone, 0.1 to 0.3% of a photoinitiator, 15.0 to 22.0% of acetic ester, 2.5 to 3.0% of a leveling agent, 0.1 to 0.2% of an antifoaming agent, 5.0 to 10.0% of butyl acetate and 10.0 to 15.0% of toluene. The UV paint provided in the invention has excellent resistance to yellowing; the preparation method for the UV paint is simple and convenient; during construction, the paint can form into a film in 20 to 23 seconds under curing by UV radiation, being rapid and highly efficient in film forming; a substrate with the formed film has the characteristics of high strength, high hardness, high wear resistance, high gloss, high weatherability, high solvent resistance, etc., and is beautiful and durable in use, not easy to turn yellow.

Description

technical field [0001] The invention relates to a paint, in particular to a yellowing-resistant UV paint, a preparation method and a construction process thereof. Background technique [0002] Coatings are used for room decoration and furniture decoration. Among them, ultraviolet curing coatings (UV coatings) have the advantages of low VOC content, fast curing speed, and good comprehensive performance of coating films. They have developed rapidly in my country and are widely used. Computer peripheral equipment, communication equipment, audio-visual equipment, consumer electronics products, auto parts and optoelectronics industry, toys, cosmetics and surface coating of various plastics, metals, bamboo and wood ware, etc. However, the existing commonly used UV coatings are prone to yellowing after a period of time, thereby affecting the aesthetics of the surface of the article. Contents of the invention [0003] An object of the present invention is to provide a yellowing-re...
