Abstract

The invention provides full water-based plastic flexible printing ink. The full water-based plastic flexible printing ink is prepared by the following raw materials by weight: 35-70 parts of printing ink connection materials, 25-50 parts of color paste, 1-10 parts of a flatting agent, 1-10 parts of a defoamer, 1-8 parts of wax emulsion, and 5-20 parts of deionized water. The color paste is prepared by mixing the following raw materials by weight: 20-55 parts of printing ink resin, 20-50 parts of organic pigments, 1-8 parts of a wetting dispersant, 1-6 parts of the defoamer, and 20-40 parts of the deionized water. The full water-based printing ink has abroad application range, and has environment-friendly feature compared with the normal water-based printing ink, and is capable of greatly reducing the pollutant residue and volatility gases on the surface of a printed matter, and realizing the zero release of VOC in the printing ink products. The full water-based printing ink has the characteristics of good adhesive force, rub resistance, scratch resistance, weather resistance, water resistance, chemical resistance, resistance and so on, and the high-speed flexible printing is more than 150 m / min.

Description

technical field [0001] The invention belongs to the technical field of printing inks, and in particular relates to a fully water-based plastic flexographic ink and a preparation method thereof. Background technique [0002] Due to its wide adaptability and economy, flexographic printing has become the fastest growing printing method at home and abroad in recent years, and because of the wide use of water-based ink in flexographic printing, water-based flexographic printing is recognized as one of the best , the most promising printing method. Since the 1970s, water-based inks have been greatly developed and have been widely used on absorbent materials such as paper and cardboard. However, flexographic water-based inks applied to non-absorbent materials such as plastic films still have problems such as slow drying speed and poor adhesion. In order to solve these technical problems, many water-based inks still add some alcohols or ethers during production or use. Such as org...
