Aqueous ultraviolet cure offset printing gloss oil

Abstract

The invention provides water ultraviolet curing offset-printing gloss oil for glazing printed matter surface. The prior ultraviolet glazing oil does not meet the residue requirements of the tobacco package industry, has certain volatility as well as irritation, and is still harmful to environment. The curing offset-printing gloss oil comprises the following components in weight percentage: 10 to 50 percent of polyurethane acrylic resin, 10 to 50 percent of epoxy acrylate resin, 5 to 20 percent of dipentaerythritol hexaacrylate, 1 to 10 percent of 4-(N, N-dimethylamino) ethyl benzoate, 1-10 percent of o-benzoyl methyl benzoate, 1 to 10 percent 4-chlorobenzophenone, 0.1 to 1.0 percent of BaBr2, 10 to 20 percent of water, 0.1 to 1 percent of organosilicon flatting agent, 0.1 to 1 percent of defoaming agents and 0.1 to 1 percent of antifogging agents. As more than 65 percent of the components of the curing offset-printing gloss oil do not volatilize, the curing offset-printing gloss oil is low in irritation and little in odor, has no solvent residue, and meets cigarette label residue requirements.

Description

technical field [0001] The invention relates to a water-based ultraviolet curing offset printing varnish used for glazing the surface of printed matter. Background technique [0002] At present, the varnishes used for glazing the surface of printed matter are diluted with organic solvents when used, and the residues of organic solvents exceed the standard, which does not meet the environmental protection requirements. For this reason, UV (ultraviolet) varnish has appeared on the market. After it is coated on the surface of printed matter, it can be cured in a short period of time under ultraviolet light, and the residue of organic solvent (voc) reaches the standard of ordinary printed matter. But it still does not meet the residue requirements of the cigarette pack industry, and the above-mentioned glazing oil has certain volatility and irritation, and is still harmful to the environment.
