Abstract

Environmentally friendly soluble ink and a preparing process thereof are disclosed. Raw materials of the ink include, by weight, 55-75 parts of modified acrylic resin, 40-55 parts of environmentally friendly pigment filler, 70-95 parts of n-butanol, 55-75 parts of absolute alcohol, 15-25 parts of a dispersant, 15-20 parts of a thickener, 35-50 parts of hyperbranched polyglycerol and 5-15 parts ofpolyoxypropylene glycerol ether. In a preparation process, the n-butanol is adopted as a solvent, the modified acrylic resin reacts with the hyperbranched polyglycerol to form glycidyl methacrylate which has carbon-carbon double bonds in acrylic resin and epoxy groups, and the epoxy groups react with hydroxyl on the surface of the polyoxypropylene glycerol ether so as to increase the number of branch chains in the glycidyl methacrylate, and therefore, the glycidyl methacrylate is improved in polarity and can form hydrogen bonds with water molecules, and dissolving performance of the ink can befurther improved.

Description

technical field [0001] The invention belongs to the technical field of ink production, in particular to an environment-friendly soluble ink and a preparation process thereof. Background technique [0002] Ink is an important material for printing. It expresses patterns and characters on the substrate by printing or inkjet painting. The ink includes main components and auxiliary components, which are uniformly mixed and rolled repeatedly to form a viscous colloidal fluid. It is composed of linking material (resin), pigment, filler, auxiliary agent and solvent, etc. It is used for various printing of books, magazines, packaging and decoration, architectural decoration and electronic circuit boards. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. [0003] With the rapid growth of China's economy and the further improvement of people's living standards, consumers have put forward higher requirements for packaging...
