Synthesis of Acrylate Copolymer Emulsion in the Presence of Macromolecule Emulsifier

摘要

Acrylic emulsion is the most widely used binder in water-based inks due to its low price, safety, resource and energy saving, and environmentally friendly. How to improve the properties of the acrylic emulsion to meet the needs of the practical application has always been an important research topic in this field. In this contribution, a series of acrylate copolymer emulsions were synthetized using binary composite emulsifiers consisting of a macromolecular emulsifier and a regular emulsifier by pre-emulsification technology. Then the effects of regular emulsifier types, neutralizing degree and the dosage of macromolecular emulsifier on properties of the emulsion such as particle size, adhesive force and thermal stability were investigated, which would provide an important guidance for the broad readerships.
