Core–shell multiple crosslinked polyacrylate emulsion for water-based ink: synthesis, characterization, and superior application performance

A multiple crosslinked polyacrylate emulsion with a high content of crosslinked monomers was successfully synthesized via core–shell emulsion polymerization. The remarkable synthesis highlights are crosslinked monomers; N-methylol acrylamide was used as the core layer monomer, vinyl triisopropoxy-silane (C-1706) and glycidyl methacrylate were used as the shell layer monomers, and aziridine (XR-100) was used as a post-crosslinking agent. In order to realize the practical application of emulsion, the optimal ratio of raw materials was investigated by orthogonal test. Furthermore, a blank acrylic resin emulsion was prepared for comparison. The structural innovation results in the excellent application potential of the emulsion prepared from the above raw materials. The most appealing aspect of this study is that the above emulsions have demonstrated excellent dryness and adhesion properties after being made into water-based inks. This study proves that the preparation of emulsions by multiple crosslinked monomers can support the synthesis and development of high-performance water-based inks and also provides theoretical and experimental basis for the synthesis of new emulsion.
