Abstract

The invention provides an alcohol-soluble modified acrylate resin without peculiar smell, which is widely applicable to various substrates such as BOPP, PE, PVC, CPP, paper, etc., and has strong adhesion fastness, good anti-blocking performance, high gloss and no Excellent properties such as odor, especially suitable for food and drug packaging and printing. In addition, the invention also discloses a preparation method of the modified acrylic resin and an ink prepared from the modified acrylic resin.

Description

technical field [0001] The invention relates to a non-odor alcohol-soluble modified acrylate resin and a preparation method thereof. Specifically, the invention relates to an alcohol-soluble modified acrylate resin for surface printing ink and a preparation method thereof, belonging to the field of polymer chemistry. Background technique [0002] As the main component of the ink, the resin plays a decisive role in the performance of the ink and the applicable solvent. Acrylate resins are used in the preparation of inks because of their light color, high transparency, and good weather resistance. The acrylic resins currently used in the preparation of inks are mainly water-based (water-based), photocurable and solvent-based acrylate resins. [0003] Water-based (water-based) acrylate resins are mainly used for water-absorbent paper printing due to the high surface tension of water and slow drying speed, but are not suitable for high-speed printing with plastic as the substr...
