Problems solved by technology

However, some acrylic emulsions commonly used in printing materials (such as water-based varnishes) are used to prepare water-based inks, and the performance is not very good, mainly because the existing acrylic emulsions are very transparent after drying, and the coloring power of the prepared inks is not good. Poor performance, need to add a lot of fillers
In addition, the gloss of the printing layer is low, especially on some corrugated packaging boxes, it looks dull. Therefore, acrylic emulsion with good hiding properties is needed to fill the vacancy in the market

Abstract

The invention relates to the technical field of covering emulsion, and in particular, relates to a water-based ink covering emulsion and a preparation method thereof. Raw materials adopted by the water-based ink covering emulsion are all conventional low-cost raw materials, so the produced water-based ink covering emulsion has low cost; the water-based ink covering emulsion contains no toxic solvent, has low VOV content, contains no free TDI and various heavy metals, and is environmentally friendly and safe; the water-based ink covering emulsion has the advantages of good covering power and good color developing effect, and an obtained printing layer has high surface glossiness; the preparation method has the advantages of simple process and high operability, can be promoted and used on large scale, and cooperates with a water-based ink covering emulsion formula for use; the produced water-based ink covering emulsion has the advantages of good covering power and good color developing effect, and the obtained printing layer has high surface glossiness.

Description

Technical field [0001] The present invention relates to the technical field of covering emulsions, and in particular to an ink covering emulsion and a preparation method thereof. Background technique [0002] As people's awareness of environmental protection continues to increase, more and more product packaging boxes are beginning to be printed with water-based inks. Traditional domestic water-based ink manufacturers generally use modified water-soluble rosin resin solution as a connecting material, and prepare water-based ink together with color paste. Modified water-soluble rosin resin is cheap and has strong tinting power, but has poor weather resistance and water resistance, and the prepared ink has poor overall performance. In recent years, acrylic emulsions have been gradually used as the binder for water-based inks. On the one hand, acrylic emulsion can promote the dispersion of pigments in water and enhance the printing adaptability of ink; on the other hand, inks...
