Abstract

The invention provides a preparation method of acrylate emulsion for waterborne printing ink. The preparation method comprises the following steps: (a) selecting materials for later use; (b) preparing pre-emulsion; (c) preparing the acrylate emulsion. The preparation method disclosed by the invention is reasonable in process arrangement, scientific and efficient in process and moderate in cost; the prepared acrylate emulsion has excellent performances such as good stability, moderate viscosity, low water absorption rate, high adhesion power and the like, and can effectively improve the performances of the printing ink, such as adhesion property, water resistance, after-tack resistance and the like.

Description

technical field [0001] The invention relates to a method for preparing an acrylate emulsion, in particular to a method for preparing an acrylate emulsion for water-based ink with high stability, excellent water resistance and adhesion, and belongs to the technical field of ink. Background technique [0002] Ink is an important material for printing. It expresses patterns and characters on the substrate through printing. Ink is generally composed of pigments, linking materials, solvents and additives. These components are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. Ink is widely used in various printings such as books, periodicals, packaging and decoration, and architectural decoration. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. At present, the packaging and printing industry mainly uses solvent-based inks. Solvent-based inks will release a large amount of toxic organic substanc...
