Preparation process of environment-friendly water-based ink

Abstract

The invention discloses a preparation process of an environment-friendly water-based ink, and belongs to the technical field of water-based ink preparation processes. The preparation process of the environment-friendly water-based ink comprises a fixed base, a grinding drum is rotatably connected to the inner side of the fixed base, cross-shaped connecting plates are fixedly connected to the top and the bottom of the grinding drum, and cams are rotatably connected to the middles of the two cross-shaped connecting plates through first rotating shafts. When an ink material is ground through a first grinding roller and the grinding drum, the grinding gap between a second grinding roller slidably connected into the first grinding roller and the grinding drum is slowly changed through a first connecting rod, and therefore when the water-based ink is ground through equipment, a large grinding space exists, and more mixed materials can be added; and the grinding gap is slowly changed during grinding, so that ink with smaller particles can be ground, the materials are ground and finely ground, and the grinding effect is improved.

Description

technical field [0001] The invention relates to the field of water-based ink preparation technology, in particular to an environment-friendly water-based ink preparation technology. Background technique [0002] Water-based inks are often used as a substitute for solvent-based inks. The raw materials of solvent-based inks contain toxic and harmful components, which will pollute the atmospheric environment. The difference between water-based ink and solvent-based ink is that the solvent used in water-based ink is not an organic solvent but water, the volatilization loss in the ink fountain is small, and there is no problem of solvent erosion on the printing plate. The biggest feature of this type of ink is that it significantly reduces the emission of organic volatiles, prevents air pollution, improves the printing environment, and is beneficial to the health of employees. In the production process of water-based ink, it is necessary to mix water-soluble resin, pigment, addi...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of environment-friendly water-based ink preparation process, to solve the above-mentioned background technology, when the current water-based ink grinding equipment is grinding, the grinding space is relatively fixed, and because the grinding space is small, when starting grinding, the added There are very few materials, and most of the materials are accumulated in the feed port, and the grinding gap is always the same size. The grinding gap cannot be adjusted, and ink with smaller particles cannot be ground, resulting in insufficient grinding fineness and lower ink quality.
