Problems solved by technology

Traditional UV screen printing varnish mostly uses polyamide wax additives to solve the problem of anti-sedimentation and anti-penetration. Although this has a certain effect on some papers, it cannot prevent penetration on thin paper or loose thick paper. , and the thickening is very serious. After the traditional UV screen printing varnish is coated on thin paper or loose thick paper, it is found that the permeability is obvious. The varnish will penetrate into the paper or even to the bottom, which seriously affects the UV curing and causes poor drying. Completely lead to a decline in market promotion

Abstract

The invention relates to the technical field of gloss oil, and in particular relates to anti-permeable UV silk printing paper gloss oil and a preparation method of the anti-permeable UV silk printing paper gloss oil. The anti-permeable UV silk printing paper gloss oil is prepared from the following components in parts by weight: 40-60 parts of acrylic resin, 15-25 parts of acrylic monomer, 8-12 parts of a photoinitiator, 2-4 parts of an organic polymeric delustering agent, and 0.5-4 parts of an assistant; the preparation method comprises the following steps: a. pre-dispersing the acrylic monomer and the organic polymeric delustering agent in a mixing pot in parts by weight, and uniformly mixing; b. continuously adding the acrylic resin, the photoinitiator and the assistant in the mixing pot in parts by weight and mixing uniformly to prepare oil; and c. filtering the oil. The anti-permeable UV silk printing paper gloss oil can achieve good anti-permeable effect, low thixotropic behavior, low influence on glossiness, excellent adhesive force, high fullness and the like, and has wide applicability.

Description

technical field [0001] The invention relates to the technical field of varnish, in particular to an anti-penetration UV screen printing paper varnish and a preparation method thereof. Background technique [0002] At present, the popular high-end wine, tobacco, cosmetics, and food packaging boxes on the market are all printed on gold and silver cardboard with UV ice frosting, wrinkles, etc. After being irradiated by UV lights, a variety of simulated artistic effects will be produced, making the printed matter appear Elegant, luxurious, dignified and with three-dimensional effects, for printing and packaging companies, this has virtually improved the market competitiveness of packaging products. These effects are the masterpieces of UV screen printing technology. Traditional UV screen printing varnish mostly uses polyamide wax additives to solve the problem of anti-sedimentation and anti-penetration. Although this has a certain effect on some papers, it cannot prevent penetra...
