A kind of ultraviolet curing gravure printing ink and preparation method thereof

Abstract

The invention discloses printing ink for ultraviolet light curing intaglio printing, which is characterized in that the printing ink is prepared by the following raw materials in parts by weight: 3-4 parts of organic pigment, 12-14 parts of epoxy acrylate, 4-5 parts of sodium peroxide powder, 10-13 parts of polyester acrylate, 5-8 parts of glycol ether, 1-2 parts of ferrocene, 10-12 parts of 6-hexanediol diacrylate, 3-4 parts of dimethoxy-2-phenylacetophenone, 1.3-1.5 parts of accelerant D, 6-8 parts of carboxymethyl cellulose, 11-14 parts of phenyl glycidyl ether, 1-2 parts of barium metaborate, 1-2 parts of antioxidant DSTP (disteaxyl thiodipropionate), 5-7 parts of 1173 photoinitiator, and 4-5 parts of assistant. According to the printing ink, the assistant improves the toughness of the printing ink, so that the printing ink is dispersed uniformly, and the stability of the printing ink is maintained. The printing ink can achieve good printing effects on a hard substrate and a soft substrate, is suitable for multiple production modes and production requirements, and is excellent in comprehensive performance.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to an ultraviolet light curing gravure printing ink and a preparation method thereof. Background technique [0002] As a kind of printing process, gravure printing has the advantages of thick ink layer, bright color, high saturation, high printing plate durability, stable quality of printed products, fast printing speed and other advantages in the field of printing, packaging and graphic publishing. occupy an extremely important position. Gravure printing inks can be divided into three categories according to their composition: solvent-based inks, water-soluble inks and UV-curable inks. Due to the volatilization of organic solvents, traditional solvent-based inks are easy to pollute the environment, cause harm to the human body, and have unsafe factors such as flammability and explosion. Although water-soluble ink does not have the disadvantages of environmental pollution...

Problems solved by technology

Due to the volatilization of organic solvents, traditional solvent-based inks are easy to pollute the environment, cause harm to the human body, and have unsafe factors such as flammability and explosion.

Although water-soluble inks do not have the unfavorable characteristics of solvent-based inks such as environmental pollution, human injury and high risk caused by solvent volatilization, they also have disadvantages such as not easy to dry, poor adhesion to plastic substrates, etc.
