Abstract

The invention discloses a tasteless direct-coating ultraviolet curing coating composition, which is prepared from the following components in percentage by weight: 15 percent to 20 percent of epoxy acrylic resin, 15 percent to 20 percent of aliphatic polyurethane, 20 percent to 40 percent of UV (Ultraviolet) monomer 30, 5 percent to 8 percent of photoinitiator, 10 percent to 22 percent of coinitiator, 0.5 percent to 1 percent of flatting agent, 0.5 percent to 1 percent of defoaming agent, 0.3 percent to 0.5 percent of antioxidant. Therefore, the ultraviolet curing coating composition preparedby adopting the formula provided by the invention has the solid content being 99.9 percent or more, is high-solid and solvent-free, has the ultraviolet curing energy being 50mJ / cm<2>, has the gloss being larger than or equal to 95 degrees (tested through a 60-degree angle) after curing, is low in smell, and meets the use requirement since the components can participate in chemical reaction and the organic matter emission is lower than 5PPM.

Description

technical field [0001] The invention relates to the technology in the field of packaging coatings, in particular to an odorless direct coating ultraviolet curable coating composition. Background technique [0002] As a branch of emerging coatings at the end of the 20th century, with the improvement of people's living standards and the rapid development of the photo industry, photo coatings meet the exquisite requirements in the field of photo album packaging; However, the current photo coatings generally have the problems of heavy odor and high organic emissions, which cannot meet the requirements of use. Contents of the invention [0003] In view of this, the present invention addresses the deficiencies of the prior art, and its main purpose is to provide an odorless direct-coating UV-curable coating composition, which can effectively solve the problems of heavy odor and high organic emission in existing photographic coatings. [0004] To achieve the above object, the pr...
