Abstract

The present invention relates to the field of ink technology, in particular to a UV screen printing plastic ink and a preparation method thereof. The UV screen printing plastic ink of the present invention consists of the following raw materials in parts by weight: 18-28 parts of polyurethane acrylate, 16-25 parts of polyester Acrylate, 6~15 parts of solid acrylic resin, 2~8 parts of TPGDA, 7~15 parts of TMPTA, 4~12 parts of HDDA, 14~22 parts of pigment powder, 1~3 parts of dispersant, 0.2~1.2 parts of silicone disinfectant Foaming agent, 1~4 parts of silicone leveling agent, 1~3 parts of photoinitiator, 0.2~1.5 parts of adhesion promoter. The present invention uses solid acrylic resin as one of the base materials, which has better flexibility and adhesion, greatly improves the printing adaptability of plastic inks, and the base materials urethane acrylate and polyester acrylate have excellent adhesion, The adhesion firmness of the present invention is further enhanced, the printing adaptability is better, and the printing effect is good.

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. ...
