Problems solved by technology

Since the water-based varnish contains silane substances with high surface tension such as water-based defoaming agents and water-based anti-scratch and wear-resistant agents, water-based varnishes are prone to shrinkage, which affects printing quality.

Abstract

The invention discloses a method for preparing water-based varnishing oil. The method comprises a feeding step and a dispersing step, wherein the feeding step comprises the sub-steps of adding latex, and then, adding a material, wherein during material adding, the material is added while dispersing, and then, the material is dispersed through the dispersing step; and the adding of each material needs the feeding step and the dispersing step. Through controlling the dispersion speed, dispersion time and feeding sequence during production, the probability that the water-based varnishing oil is subjected to a hole shrinkage phenomenon is inhibited.

Description

technical field [0001] The invention relates to a method for preparing ink, in particular to a method for preparing water-based varnish for printing. The water-based varnish prepared by the method is not prone to shrinkage. Background technique [0002] Water-based varnish is mainly composed of main agent, solvent and auxiliary agent. It has the characteristics of colorless, odorless, strong transparency and non-toxicity, no organic volatile matter, low cost, and wide source. It is especially suitable for packaging and printing. [0003] Water-based varnish is a surface protective ink that is widely used in printing products at present. Water-based varnish usually uses water-based styrene-acrylic emulsion, water-based pure benzene emulsion, solid acrylic alkali-soluble resin, water-based leveling agent, water-based defoamer, water-based Anti-scratch and wear-resistant agent, water-based wetting agent, water-based anti-scratch and wear-resistant agent, water, and alcohol.
