Description

Formula and preparation method of ink for green printing

Technical Field

The invention relates to the technical field of printing ink, in particular to a formula of ink for green printing and a preparation method thereof.

Background

The ink is a uniform mixture composed of color bodies (such as pigments, dyes and the like), connecting materials, filling materials, additives and the like; printing can be carried out, and drying is carried out on the printed body; is a colored pasty adhesive with certain fluidity. Thus, color (hue), body (rheology such as thickness, fluidity, etc.) and drying properties are the three most important properties of the ink. They are of many kinds, vary in physical properties, some are thick, sticky, and some are quite thin. Some vegetable oil is used as a connecting material; some use resin and solvent or water as connecting material. These are determined according to the object to be printed, i.e., the substrate, the printing method, the type of printing plate, the drying method, and the like.

Printing ink used in the market at present has pungent smell, and when workers print, the printing ink breathes the smell emitted by printing all the time, so that the influence on the bodies of the workers is easy to cause, and the printing ink is not green and safe enough, and the formula and the preparation method of the printing ink for green printing are to be improved.
