Abstract
Epoxy resin emulsion was prepared by using self-made star-shaped emulsifier.The effects of emulsifier structure on epoxy resin emulsion stability and film performance were studied and the main parameters of emulsifier in the preparation of epoxy resin emulsion were optimized.The results showed that the epoxy resin emulsion have high stability and excellent film forming properties when the molar ratio of epoxy groups to hydroxyl groups in polyethylene glycol and epoxy resin E-20 was 1.5 ∶ 1.0,the polyethylene glycol molecular weight was 4 000 and the amount of the emulsifier was 10%.
