Problems solved by technology

However, the concealing effect of the commonly used concealing emulsions on the market is not ideal. When configuring ink, a relatively large amount of pigment needs to be added to meet the requirements of hiding and tinting strength, and the cost of ink formulation increases.

Abstract

The invention belongs to the technical field of water-based emulsions, and particularly relates to a covering emulsion having performance of improving coloring and covering power and a preparation method thereof. The covering emulsion having the performance of improving coloring and covering power is composed of the following components in parts by mass: 5 to 10 parts of a modified polymer, 25 to32 parts of styrene, 10 to 15 parts of acrylic acid, 2 to 5 parts of a nonionic emulsifier, 1 to 3 parts of an emulsifying composition, 0.1 to 0.3 part of an initiator and 40 to 50 parts of deionizedwater. The covering emulsion having the performance of improving coloring and covering power and provided by the invention has good covering power and color development effect, and the surface gloss of a printing layer can be remarkably improved when the covering emulsion is applied to water-based ink.

Description

technical field [0001] The invention belongs to the technical field of water-based emulsions, and in particular relates to a covering emulsion with improved coloring and hiding performance and a preparation method thereof. Background technique [0002] With the enhancement of people's awareness of environmental protection and the continuous development of water-based resin products, more and more packaging papers have begun to use water-based inks for printing. Domestic water-based ink manufacturers usually use acrylic emulsion as the binder of water-based ink. Acrylic emulsion has wetting and dispersibility for pigments, which can enhance the printing adaptability of water-based ink. The water-based ink prepared with acrylic emulsion has the characteristics of good weather resistance and water resistance, which can greatly improve the grade of water-based ink. However, the acrylic emulsion has the characteristics of being transparent after drying, and the prepared ink has...
