Water-based printing ink and application thereof

Abstract

The invention discloses environment-friendly water-based printing ink suitable for cigarette filter printing. The printing ink takes water as a main solvent and has innocuity, and no peculiar smell; and the adhesive force, the drying property and the water resistance of the printing ink can meet the printing and product requirement. The preparation raw material components comprise: a high acid value acrylic resin amination liquid (A), which is a water-soluble resin liquid made from high acid value acrylic resin through amination, wherein the high acid value is in the range of 140-280 mg KOH / g, preferably in the range of 180-260 mg KOH / g, and most preferably in the range of 215-225 mg KOH / g, and an acrylate copolymer emulsion used as an film forming agent. In a typical embodiment, the raw material components comprises the high acid value acrylic resin amination liquid (A), the acrylate copolymer emulsion (B and C), nontoxic and harmless inorganic and organic pigment (D), superfine light calcium carbonate used as a filling material, water used as a main solvent, small amount of alcohol solvent and functional additives. The printing ink prepared is suitable for intaglio printing, and has the characteristics of environmental friendliness, high drying speed, resistance to wet friction, high adhesive force, good printability and the like.

Description

technical field [0001] The invention provides an environment-friendly printing ink suitable for printing cigarette filters, in particular a gravure printing ink capable of printing tipping paper on a rotary gravure printing machine. The ink is non-toxic, non-odor, adhesion and drying speed can also meet printing requirements. Background technique [0002] The current cigarette packaging printing industry mostly uses alcohol-soluble gravure printing inks, which use a large amount of alcohols and acetate solvents, especially the tipping paper used for filters, and the alcohols and esters used in inks have relatively large residues The amount will have a certain impact on the health of long-term smokers. The tobacco industry generally expects a new type of environmentally friendly ink that uses water as the main solvent and whose printing performance meets the requirements. However, when water-based inks are used, it is difficult to achieve long-term stability of the added in...

AI Technical Summary

Problems solved by technology

Although this kind of ink is non-toxic and harmless, it is difficult for the pigment to exist in the ink system uniformly for a long time

[0003] On the other hand, using water-based ink to print tipping paper, its drying speed is often not as good as that of oil-based ink, and it is difficult to dry in time after the paper is printed and before it is rolled up or overlapped
