Novel ink for rotary printing

Abstract

The invention relates to the technical field of ink, in particular to novel ink for rotary printing. The ink is made from the following components according to parts by weight: 8-12 parts of acrylic emulsion, 3-5 parts of vinyl acetate and vinyl copolymerized emulsion, 4-6 parts of glycidyl acrylate, 1-3 parts of hydroxypropyl methyl cellulose, 0.5-2 parts of nitrocellulose, 0.2-0.8 part of dioctyl phthalate, 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, 5-8 parts of ethanol, 2-3 parts of methyl cis-9-octadecenoate, 1-3 parts of dimethyl siloxane, 1-3 parts of C9 petroleum resin, 1-1.5 parts of polyethylene glycol, 0.1-0.5 part of a preservative, 0.2-0.3 part of a defoaming agent and 1-3 parts of dyestuff. The novel ink is well adaptable to rotary printing, can well permeate sheets of paper, and can dry quickly through permeation so that printing blur due to excessive mobility of the ink is avoided.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a novel 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 ink with high flu...

AI Technical Summary

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.
