Abstract

An environment-friendly water-based ink comprises the following components by mass percent: 12-22% of alcohol-soluble modified acrylic resin, 10-20% of alcohol-soluble modified aldehyde ketone resin, 35-55% of a diluents, 6-12% of methyl ether, 12-20% of pigment, and 2-5% of a functional auxiliary agent. The environment-friendly water-based ink provided by the invention is an alcohol-soluble gravure ink, adopts more than 95% of alcohol as the auxiliary agent to realize gravure production, is stable in ink performance, uniform in texture, strong in tinting strength, not easy to precipitate, and similar with the printing effect of the traditional offset printing, and has certain antistatic function.

Description

A kind of Environmental-protection water-based ink

Technical field

The present invention relates to a kind of ink, particularly a kind of water color ink.

Background technology

Along with social development and progress, people are more and more higher to the concern of quality of life and life comfort level, specification of quality for print product is also more and more stricter, not only need printed matter itself to there is extraordinary printing effect, and for printshop ink, should reduce as much as possible it for the bad harm of surrounding environment and person generation.

In existing gravure printing technique, adopt all kinds of SOLVENTS type ink system more, to reaching good printing effect, but the existence due to non-feature of environmental protection solvent, can more or less to environment, impact, especially organic solvent type ink, can cause detrimentally affect to surrounding environment.

On the other hand, for reducing the harm to surrounding environment, some solvent type inks adopt alcohol dissolubility or water-soluble system, but still use traditional mask-making technology, not pointed, do not reach higher printing effect, so that can not be widely used.

Summary of the invention

Goal of the invention: for above-mentioned deficiency, overcome the defect of prior art, the object of this invention is to provide that a kind of to have the alcohol solution that good print effect has environmental-protecting performance concurrently be simultaneously Environmental-protection water-based ink.

Technical scheme of the present invention: a kind of Environmental-protection water-based ink, is comprised of the component of following mass percent:

Alcohol is molten acrylic resin modified: 12-22%;

The molten modification aldehyde ketone of alcohol resin: 10-20%;

Thinner: 35-55%;

Methyl ether: 6-12%;

Pigment: 12-20%;

Functional agent: 2-5%.

As preferably, thinner is that concentration is more than 95% ethanolic soln.

As preferably, functional agent comprises anti-settling agent and static inhibitor.

As preferably, anti-settling agent is polyamide wax anti-settling agent, the 1-3% that mass content is total ink.。

As preferably, static inhibitor is the molten static inhibitor of anionic alcohol, the 1-3% that mass content is total ink.

Beneficial effect: Environmental-protection water-based ink provided by the invention, it is a kind of alcohol dissolubility base gravure ink, what adopt is that 95% above alcohol meets intaglio plate production as auxiliary agent, the transfer bad phenomenon of the gravure site that it is can not only fine solution traditional,, there is not the residual of solvent and toxic substance simultaneously in the site of the high light part of good reproduction 3%.

Simultaneously for reaching more preferably effect, Environmental-protection water-based ink provided by the invention, improving traditional intaglio plate in use, especially the recess engraving degree of depth and site are big or small, two background colors with 3% transition net for example, background color one adopts the mask-making technology of 70-85 line, 45-55 μ, background color two adopts the mask-making technology of 100-120 line, 37-51 μ, than traditional recess engraving technique shallow 10 μ, so just can better meet the various process requirements of Environmental-protection water-based ink provided by the invention in intaglio printing is produced.In addition, in viscosity controller, the viscosity controller of ink, in 16 seconds (No. 3 measuring cups) left and right, so just can make in intaglio printing 3% site perfect reproduction aborning.

And, the Environmental-protection water-based ink that technical solution of the present invention provides, ink performance is stable, quality homogeneous, strong coloring force, is not prone to deposited phenomenon, and has certain antistatic property, approaches the printing effect of traditional offset printing.
