Abstract

The invention discloses water-based acrylic emulsion resin, a water-based coating emulsion and a preparation method. The water-based acrylic emulsion resin is prepared from a reactive emulsifier SR-10, has stable storage and film performance and can improve the water resistance and solution resistance of a coating. Besides, isobornyl acrylate with a relatively large non-polar side group is taken as a functional monomer and can improve infiltration and adhesion performance of a BOPET(biaxially-oriented polyethylene terephthalate) film and improve the alcohol resistance of a resin system. According to the water-based coating emulsion, water-based melamine resin replaces conventional isocyanate or aziridine to serve as a crosslinking agent, the toughness, the adhesive force and the solution resistance of the coating are improved, and the printing and dyeing property of the resin system can be improved through introduction of amino resin.

Description

technical field [0001] The invention relates to the field of polymer coatings, and mainly relates to a water-based acrylic emulsion resin, a water-based coating emulsion and a preparation method, which can be used to enhance the printing adhesion of a BOPET film with a carbon ribbon. Background technique [0002] The electronic label that can be printed and printed with carbon ribbon is composed of base material, adhesive, and release material. The key part is the base material.
