Abstract

The invention provides an emulsion stabilizer for preventing excessive emulsification of ink, and belongs to an ink assistant. The emulsion stabilizer is prepared by compounding an anti-emulsificationcomponent, lecithin and a nonionic surfactant. According to the invention, lecithin is compounded with an anti-emulsifying component and a water-in-oil type nonionic surfactant, so that good stability is achieved; and after the emulsion stabilizer is added into ink, the shear viscosity and leveling property of ink can be improved, the ink can be endowed with excellent hydrophobic property, the ink is emulsified in the kneading and squeezing process and quickly achieves water-oil balance, and the water-based ink has a better effect of controlling the emulsification of the ink.

Description

Technical field [0001] This application belongs to the field of inks, and relates to auxiliary agents used in inks, and in particular to an emulsion stabilizer that prevents excessive emulsification of inks. Background technique [0002] Ink is an important material used for printing packaging materials. It displays patterns and words on the substrate through printing. The ink includes main and auxiliary components, which are uniformly mixed and repeatedly rolled to form a viscous colloidal fluid. Offset printing ink is mainly composed of resin, mineral oil and pigment. Because there are more hydrophilic polar groups in the ink, during the printing process, the fountain solution is dispersed in the ink as fine droplets under certain conditions, or the ink is dispersed in the water as a whole to form an emulsion. The phenomenon of ink emulsification, the process of ink emulsification is indispensable and inevitable, but excessive emulsification will cause problems such as light h...
