Description

technical field [0001] The invention relates to the technical field of water-based emulsions, in particular to a covering emulsion for water-based inks and a preparation method thereof. Background technique [0002] As people's awareness of environmental protection continues to increase, and various countries have successively issued corresponding laws and regulations to limit VOC emissions, and the control is becoming more and more stringent. Under this general situation, more and more printing and packaging have begun to use water-based inks in large quantities. . In the field of gravure printing for kraft paper bags and flexographic printing for corrugated cardboard, in order to improve the shortcomings of ordinary water-based inks such as poor hiding and poor coloring power after drying, a covering emulsion is often used as a non-film-forming emulsion. However, the concealing effect of the commonly used concealing emulsions on the market is not ideal, and a relatively l...
