Recent Research Advances on Binder Resin for Water-Based Ink

With the increasing of environmental protection awareness, water-based ink has been the research keynote in printing and packaging areas. In this study, the development of water-based ink was introduced firstly. Then, it can find that the performance of water-based ink is decided by water-based binder. The novel polymers including waterborne polyurethane and polyacrylate were used as water-based binders＇ resin. Moreover, the development and research methods of polyacrylate were presented briefly. As a kind of new resin, the development and research methods of waterborne polyurethane were described in detail. Improving synthesis process and adding modifiers were the main methods to improve performance of waterborne polyurethane. Since the incorporation of nanomaterials into polymer matrix could meet the performance requirements of water-based binders for printing ink, the nanomaterial modified technology was regarded as the keynote in water-based ink research field at home and abroad. Finally, the main research direction of new water-based binders used as ink resin were shown clearly.
