AI Technical Summary
Technical Problem
Traditional water-based acrylic inks suffer from poor adhesion, non-biodegradability, and high VOCs. Existing modification methods often compromise their environmental performance.
Method used
Polyhydroxyethyl cellulose acrylate was prepared by grafting acrylic acid onto hydroxyethyl cellulose. This acrylate was then mixed with waterborne acrylic ink resin using the principle of similar compatibility. In combination with specific reaction steps and additives, a biodegradable modified waterborne ink resin was prepared.
Benefits of technology
It improves the adhesion and biodegradability of water-based inks while reducing VOC content and maintaining the excellent performance of the resin.

Abstract
This invention relates to the field of waterborne acrylic ink preparation technology, and discloses the synthesis and application of polyhydroxyethyl cellulose acrylate. The polyhydroxyethyl cellulose acrylate is synthesized by esterification of the carboxyl group of acrylic acid with the hydroxyl group of hydroxyethyl cellulose, resulting in hydroxyethyl cellulose acrylate (HEC-AA). HEC-AA is then polymerized through the addition of its active double bonds to form PHECA resin. The dehydrated PHECA is applied to the preparation of waterborne acrylic ink resin, solving the technical problems of high VOCs, low adhesion, and non-biodegradability in existing waterborne acrylic inks.
