Abstract

The invention discloses an elastic emulsion for water-based ink, which is prepared by the following raw materials comprising, by weight, 5 to 8 parts of styrene, 3 to 5 parts of ethyl acrylate, 32 to 35 parts of butyl acrylate, 1 to 2 parts of itaconic acid mono-n-butyl ester, 1 to 2 parts of N-hydroxymethyl acrylamide, 5 to 10 parts of acrylic ester resin liquid, 0.05 to 0.1 part of sodium bicarbonate, 2 to 3 parts of composite emulsifying agent, 0.35 to 0.5 part of composite initiating agent and 35 to 45 parts of deionized water. The invention further discloses a preparation method of the elastic emulsion for the water-based ink and the water-based ink utilizing the elastic emulsion. The water-based ink prepared by utilizing the elastic emulsion serving as a binder has good rheological property, printing adaptability and folding resistance, and the elasticity is good after a film is formed.

Description

technical field [0001] The invention relates to an elastic emulsion for water-based ink and a preparation method thereof, and to a water-based ink using the elastic emulsion. Background technique [0002] Due to its excellent resilience, flexibility, adhesion, weather resistance and other properties, elastic emulsion is widely used in elastic latex paint, elastic putty and elastic coating, especially in the construction field. But it is rarely used in water-based inks. [0003] Rheology is one of the most important basic properties of water-based inks. Rheology plays a major role in the precipitation and aggregation of pigments in water-based inks, printing transferability and leveling and film-forming properties, and the emulsion used as water-based inks directly affects the rheology of water-based inks.
