Water printing ink using synthetic water solid acrylate resin as base material and its preparation method

Abstract

A water ink based on the synthetic solid water acrylic resin is prepared through water-phase suspension copolymerizing reaction between acrylic acid monomer mixture and ammonium persulfate as trigger in water while stirring to obtain solid water acrylic resin, dissolving it in water, cosolvent, or amine, adding pigment, water and assistant, and grinding. Its advantages are high safety, adhesion and resistance to water and rubbing, not coloring, and low cost.

Description

technical field

[0001] The invention belongs to printing ink and its production process, in particular to water-based printing ink and its production process. Background technique

[0002] The liquid ink widely used in the packaging and printing industry currently uses toxic and harmful substances such as aromatic hydrocarbons, esters, and ketones as solvents, and the content of organic solvents in inks is generally 50% to 70%. Most of these solvents will volatilize during the printing process. A printing workshop with an ink consumption of 30 tons / year releases more than 20 tons of organic solvents into the atmosphere every year, which seriously pollutes the workshop and the atmosphere. The health of surrounding residents poses a serious threat. In addition, the ink stored in the workshop is a flammable and explosive substance, which is also a hidden danger to the safety of the factory. The residual solvent in the ink has a certain influence on the quality of the package ...
