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 relates to the field of high polymer materials, and discloses UV (ultraviolet) printing ink which is prepared from the following raw materials in percentage by weight: 20-30% of waterborne urethane acrylate; 10-15% of a pigment and filler; 10-15% of absolute ethyl alcohol; 3% -4% of a surfactant; 1% -3% of an assistant; 3% -5% of a photoinitiator and balance of deionized water, the smell of the ink is small, the irritation is small, and the printing ink is good in mechanical property, excellent in adhesive force, good in chemical resistance and smooth and bright and clean in appearance after being cured. In use, both performances and environmental protection are taken into consideration. The water-based ink disclosed by the invention is suitable for various printing modes, and can be applied to printing of packaged foods, medicines and the like.

Description

technical field [0001] The invention relates to the field of inks, in particular to a 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 increase printing costs and ener...
