Problems solved by technology

[0003] However, unlike traditional oil-soluble inks, water-based inks mostly need to dry and remove water from the wet film before curing, which reduces printing efficiency. At the same time, additional drying equipment is required to increase printing costs and energy consumption.

Abstract

The invention provides a quick-drying waterborne UV ink. The ink is prepared from, by weight, 20-30% of waterborne urethane acrylate, 10-15% of filler and pigment, 10-15% of absolute ethyl alcohol, 3-4% of surface active agent, 1-3% of additive, 3-5% of photoinitiator, and the balance deionized water. The ink is small in odour, small in irritation, good in mechanical property, excellent in adhesive force, good in chemical resistance and smooth and clean in appearance after solidification. In use, the ink gives consideration to both of properties and environmental friendliness. The ink is suitable for various printing modes, and can be applied to the printing of food packaging, dug packaging and the like.

Description

technical field [0001] The invention relates to the field of inks, in particular to a quick-drying water-based UV ink. Background technique [0002] Water-based ink (Water-based ink) is referred to as ink for short. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through compound grinding. Water-based ink is especially suitable for packaging and printing products that require strict hygienic conditions such as tobacco, alcohol, food, beverages, medicines, and children's toys. Because water is used as the solvent carrier, water-based ink has remarkable environmental protection and safety features: safe, non-toxic, non-flammable and non-explosive, and almost no volatile organic gases are produced. [0003] However, unlike traditional oil-soluble inks, most water-based inks need to dry and remove water from the wet film before curing, which reduces printing efficiency. At the same time, additional drying equipment is required to increas...
