Description

Chlorine-containing water-based ink and preparation method and application thereof
Technical Field
The invention belongs to the field of water-based ink, and particularly relates to chlorine-containing water-based ink as well as a preparation method and application thereof.
Background
Polyethylene (PE) and polypropylene (PP) films are the main printing materials because of their tasteless, non-toxic, corrosion resistant, rust resistant, lightweight, high temperature resistant, aging resistant, long service life, excellent surface finish, sufficient thermal stability, low heat fusion rate, and excellent surface smoothness. However, PP and PE are materials which are difficult to adhere to each other, and have small surface tension and low polarity. The general material is difficult to react with PP and PE to generate binding force. Particularly, after the ink is made into water, the water ink is difficult to wet the surface due to the high surface tension of water, and the water ink is difficult to spread on the surface, so that the printing and coating are difficult.
It is common practice to form polar groups on the surface of a layer of PP and PE by some physical means to modify the surface tension and the printing and coating effects. However, this approach has certain limitations. And the water-based ink in the prior art has the technical defects of poor abrasion resistance and heat resistance, large color difference, easy separation or falling among the base material, the ink layer and the plastic film and the like when being used in a curtain coating process.
