Ultraviolet light cured printing ink

Abstract

The invention discloses the ultra-violet light solidified printing ink. The ultra-violet light solidified printing ink hasn't volatile organic solvent, avoiding the pollution and improving the durability and flexible. The invention uses the national standard GB / T 1731-93 to test, and the baseboard uses soft PVC film. The invention uses national standard GB / T 1766-95 to test durability, and uses GB / T 1865-97 to test printing ink. The flexible is 1mm, the discoloration is 2 grade, the efflorescence is 0 grade, and the cracking is 0 grade.

Description

technical field [0001] The invention relates to a printing ink, in particular to a screen printing ink dried by ultraviolet light curing. Background technique [0002] UV-curable printing screen ink is printed on the substrate by screen printing, and the curing reaction is completed by ultraviolet curing to form the final product. Compared with traditional volatilization-drying or oxidative-drying printing inks, UV-curable printing inks do not contain volatile organic solvents (VOCs), thus avoiding water and air pollution. [0003] UV curing ink not only has the advantages of environmental protection, but also has the characteristics of fast curing speed, which can greatly improve production efficiency and meet the requirements of modern high-speed printing. [0004] Screen printing is a printing method that transfers ink from the printing plate hole to the substrate by squeezing the squeegee. The printing plate is basically composed of soft screen and photosensitive latex...
