AI Technical Summary

Problems solved by technology

It has a great influence on the viscosity, adhesion, gloss, drying and printing adaptability of the ink. As the most commonly used water-based resin, acrylic resin needs to increase the thickness of the ink film in order to obtain good tinting strength. This indirectly The drying speed of the ink is reduced, and the second is by increasing the content of the pigment, but the increase of the pigment content will increase the viscosity of the ink, resulting in a decrease in the drying speed, gloss, water resistance, tinting power and adhesion

Description

technical field [0001] The invention belongs to the technical field of ink printing, and in particular relates to a water-based ink applied to paper printing. Background technique [0002] Water-based ink is referred to as Yanhuang ink for short, and flexographic water-based ink is also called liquid ink. 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. Water-based ink is a uniform paste-like substance composed of binders, pigments, additives and other substances. The binder provides the necessary transfer performance of the ink, and the pigment gives the ink its color. The binder of water-based ink is mainly divided into two types: water-diluted and water-dispersed. There are many types of resins that can be used in th...
