Ultraviolet (UV) screen plastic film printing ink and method for preparing same

Abstract

The invention relates to the technical field of ink, and in particular relates to an ultraviolet (UV) screen plastic film printing ink and a method for preparing the same. The UV screen plastic film printing ink consists of the following raw materials in parts by weight: 18-28 parts of urethane acrylate, 16-25 parts of polyester acrylate, 6-15 parts of solid acrylic resin, 2-8 parts of 2-propenoic acid, 1, 1'-[(1-methyl-1, 2-ethanediyl) bis [oxy(methyl-2, 1-ethanediyl)]] ester (TPGDA), 7-15 parts of trimethyl propane triacrylate (TMPTA), 4-12 parts of hexanediol diacrylate (HDDA), 14-22 parts of pigment powder, 1-3 parts of dispersing agent, 0.2-1.2 parts of organic silicon defoamer, 1-4 parts of organic silicon flatting agent, 1-3 parts of photoinitiator and 0.2-1.5 parts of adhesion promoter. The UV screen plastic film printing ink adopts the solid acrylic resin as one basic material and has good flexibility and adhesiveness, the printing adaptability of the plastic film printing ink is greatly improved, moreover, the basic materials of the urethane acrylate and the polyester acrylate all have excellent adhesiveness, the adhesion firmness of the UV screen plastic film printing ink is further increased, and the UV screen plastic film printing ink has a good printing adaptability and a good printing effect.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a UV screen printing plastic ink and a preparation method thereof. Background technique [0002] With the rapid development of China's packaging industry in the past ten years, China's ink industry has also been greatly expanded. At present, the human environment is constantly being destroyed and has begun to threaten the human living environment. Therefore, providing environmentally friendly inks for packaging and printing has always been the goal pursued by most ink manufacturers. Screen printing UV ink does not contain heavy metals, and has low VOC emissions and harmful solvent content. It does not need to use too many irritating cleaning agents in the process of printing and screen cleaning and recycling, which greatly reduces the irritation during printing and screen cleaning and recycling. The amount of cleaning agent used meets the requirements of environmental protection. ...
