Problems solved by technology

[0003] Traditional UV-curable fission screen printing inks have unstable adhesion when printed on gold and silver cardboard, laser transfer paper and PET. When the paper or card is bent, the pattern will change due to the lack of flexibility of the ink. , at the same time, it is easy to wear and scratch during the production and use of ink

Abstract

The invention discloses ultraviolet light curing silk-screen fission printing ink. The silk-screen fission printing ink is prepared from, by weight, 30-40 parts of TPGDA, 5-10 parts of trimethylolpropane triacrylate, 5-10 parts of ethoxyquin trimethylolpropane triacrylate, 20-30 parts of epoxy resin, 20-30 parts of polyurethane resin, 4.8-7 parts of photo initiator, 0.1-0.3 part of polydimethylsiloxane and 0.3-1 part of a lubricant. The silk-screen fission printing ink has the advantages of being good in flexibility, high in adhesive force and good in wear resistance.

Description

technical field [0001] The invention relates to the technical field of screen printing fission ink, in particular to an ultraviolet light-curable screen printing fission ink. Background technique [0002] With the development of the commodity economy and the improvement of living standards, people have put forward higher requirements for packaging and printing. Due to the limitations of lithography, gravure and letterpress printing, screen printing has the characteristics of thick ink layer, small printing pressure, soft layout and wide range of printing materials, so it has played an advantage in high-end packaging products. Especially in recent years, etching, ice flower, and refraction (laser) screen printing methods have been used in cigarette and wine gift packaging, which has made a qualitative leap compared with traditional printing and packaging. It is characterized by bright colors, luxury, and elegance. Ideal packaging method for famous and high-quality products. ...
