Abstract

The invention relates to the technical field of printing ink and especially relates to improved waterless offset printing ink for thin paper printing and a preparation method thereof. The improved waterless offset printing ink comprises, by weight, 15 to 24% of an organic pigment, 25 to 30% of phenol-formaldehyde resin, 10 to 15% of a solvent, 25 to 35% of linseed oil, 1 to 1.5% of tetra[beta-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyloxy]pentaerythritol ester, 0.3 to 0.8% of a tackifier, 1 to 2% of a dryer and 1 to 5% of an additive. The improved waterless offset printing ink for thin paper printing has the characteristics of high viscosity and low stickiness. The improved waterless offset printing ink for thin paper printing has a very low VOC volatilization rate. The improved waterless offset printing ink for thin paper printing does not adopt a fountain solution, avoids exhaust gas and waste liquid discharge and satisfies green environmental protection requirements.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to an improved waterless offset printing ink suitable for thin paper printing and a preparation method thereof. Background technique [0002] Printing requires ink, and the environmentally friendly inks often used in the printing industry can be divided into water-based inks and water-free inks. The water-based ink uses the principle of water and ink repelling each other. On the same metal plate, there are both water and ink, so the key factor for the quality of the printed product is the balance of water and ink, and the water supply system. It is the direct factor of many ills in water printing and it is difficult to control. However, common anhydrous inks commonly used at present have high viscosity and poor fluidity. When printing 50-80g dictionary-like thin paper, it is easy to cause problems such as poor transfer, insufficient gloss, rubber peeling, and ink accumulation...
