Problems solved by technology

Ordinary inks generally contain toxic substances such as benzene, and the VOC content is relatively high, generally around 30%, which is much higher than the national environmental protection ink requirements. It has a damaging effect on human health and the environment, and is not environmentally friendly.
[0003] In addition, in the process of rotary printing, the paper used is mostly offset paper and newsprint, the paper strength is poor, the printing speed is fast, and the usual ink adaptability is insufficient. There are high requirements for the viscosity and fluidity of the ink, and the ink viscosity is required. , High fluidity, but if the ink with high fluidity does not penetrate well on the paper, the printing effect will be poor. At the same time, the penetration effect of the ink also affects the drying of the ink after printing.

Abstract

The invention relates to the technical field of ink, in particular to environment-friendly ink for rotary printing. The environment-friendly ink comprises, by weight, 2-5 parts of methyl methacrylate, 5-8 parts of butyl acrylate, 3-8 parts of hydroxypropyl methacrylate, 2-5 parts of butyl acetate, 3-5 parts of organosilicon modified polyester resin, 1-3 parts of fumaric acid, 15-18 parts of alcohol, 3-5 parts of 2-methyl-2, 4-pentadiol, 2-3 parts of cis-9-octadecenoic acid methyl ester, 1-3 parts of dimethyl siloxane, 3-5 parts of C9 petroleum resin, 1-1.5 parts of polyethylene glycol, 0.1-0.5 part of preservative, 0.2-0.3 part of defoamer and 2-5 parts of pigment. The environment-friendly ink has high adaptability to rotary printing, viscosity and fluidity of the ink can balance each other, the ink can be easily printed on paper in the process of rotary printing, and the fluidity of the ink can't go so far as to cause double image on the paper; the ink has permeability on the paper and can be quickly dried through permeation, so that printing slur caused by over-high fluidity is avoided.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to an environment-friendly ink for rotary printing. Background technique [0002] Ink is the main raw material used in the printing industry. The composition and performance of ink directly affect the quality and effect of printing. Ordinary inks generally contain toxic substances such as benzene, and the VOC content is relatively high, generally around 30%, which is far higher than the national environmental protection ink requirements. It has a damaging effect on human health and the environment, and is not environmentally friendly. [0003] In addition, in the process of rotary printing, the paper used is mostly offset paper and newsprint, the paper strength is poor, the printing speed is fast, and the usual ink adaptability is insufficient. There are high requirements for the viscosity and fluidity of the ink, and the ink viscosity is required. 1. The fluidity is high, but if the i...
