Abstract

The invention discloses ultraviolet curing matte coating gloss oil with high pollution resistance. The ultraviolet curing matte coating gloss oil is prepared from, by weight percent, 55-85% of positive ion curable compound, 3-15% of free radical curable compound, 6-18% of extinction powder, 0.1-6% of curable surface assistant, 3-12% of photoinitiator, and 0.5-5% of assistant. The ultraviolet curing matte coating gloss oil with high pollution resistance can be constantly cured under the conditions of ordinary ultraviolet light and H-UV and LED-US narrow wave section ultraviolet light; the gloss oil adopts a flexible printing or glue printing coating method; the post-printing coating is carried out on a plastic substrate and a paper printing product, and the gloss oil is featured by matte and high transparency; the printing product surface is protected on the basis of not influencing the appearance of the printing product basically; the pollution resistance of the printing product is obviously improved, and the durability of the printing product is improved.

Description

technical field [0001] The invention relates to an ultraviolet curing matte coating varnish for flexographic coating or offset printing coating. Background technique [0002] Coating is another post-press process for decorating and protecting printed matter developed after lamination. Coated paper prints are biodegradable and will not produce secondary pollution like plastic films; they can be coated online, and can be operated online after adding coating devices to gravure printing machines, offset printing machines and flexographic printing machines , Improve machining accuracy and speed. UV coating varnish is a new technology that emerged in the 1970s. After years of development, it has made great progress. It is an environmentally friendly product that is widely accepted and respected besides water-based varnish. , to initiate the polymerization reaction. It can be changed from liquid to solid in an instant, with fast curing speed and low curing energy consumption. Th...
