Abstract

An UV polishing and priming-free UV coating is prepared by raw materials in parts by weight as follows: 35-40 parts of epoxy acrylate, 20-25 parts of polyether acrylate, 10-12 parts of trimethylolpropane triacrylate, 5-8 parts of isobornyl acrylate, 1-2 parts of triethanolamine, 3-4 parts of tert-amylphenol, 1-3 parts of tetraethylammonium tetrafluoroborate, 2-4 parts of benzyltriphenylphospho, 1-2 parts of trifluoro acetyl acetone, 4-5 parts of 2,4,6-trimethyl benzoyldiphenyl phosphine oxide, 2-3 parts of benzil dimethyl ketal and 4-5 parts of a dispersing auxiliary. The UV coating has excellent water resistance, hot water resistance, drug resistance, caking property, toughness and flame retardant property, has excellent binding property with printing ink, and has the characteristics of high glossiness, good levelling property, small flavor, good wear resistance and the like; and only one procedure is required when UV gloss oil is adopted for UV polishing, the priming step is omitted, the operation cost is saved, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a UV glazing-free primer-free UV coating and a preparation method thereof. Background technique [0002] With the development of the market economy, great changes have taken place in the field of coatings. Among them, UV coatings have the advantages of fast curing speed, energy saving, room temperature curing, superior performance, and environmental protection. The surface is strong and heat-resistant, and the refraction effect is good, so that the substrate has a strong sense of subject. It has been widely used in chemical industry, machinery, electronic light industry, communication and other fields. Due to its environmental protection advantages, UV curing has received strong support from relevant environmental regulations and close attention from the industry. While the market demand for UV radiation curing materials is growing rapidly, UV radiation curing systems are being combined w...
