A kind of preparation technology of environment-friendly water-based ink

Abstract

The invention discloses an environment-friendly water-based ink preparation process in the technical field of water-based ink preparation technology. The middle part of the plate is rotatably connected with a cam through the first rotating shaft; when the ink material is ground by the first grinding roller and the grinding cylinder in the present invention, the first connecting rod is used to slowly change the second grinding roller slidingly connected in the first grinding roller. The grinding gap between the roller and the grinding cylinder, so that when the water-based ink is ground in the equipment, there is a large grinding space, and more mixed materials can be added, and the grinding gap changes slowly during re-grinding, which can grind out smaller Granular ink, grinding and finely grinding the material to improve the grinding effect.

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 water-solvent inks. The raw materials of water-solvent inks contain toxic and harmful ingredients, which will pollute the atmospheric environment. The difference between water-based ink and water-solvent ink is that the water solvent used in water-based ink is not an organic water solvent but water, and the volatilization loss in the ink fountain is small, and there is no problem of water 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-solub...

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.
