Study of Epoxy Resin Emulsion by Emulsion Graft Polymerization

摘要

In the paper, the emulsion graft polymerization is used to prepare stable epoxy resin emulsion by vinyl acetate and polyvinyl alcohol (PVA) as emulsification stabilizer. It is studied for the influence on the properties of emulsion by temperature and dosages of functional monomer, acrylamide and acrylic acid, and initiator. The results show that the optimal conditions: reactive temperature is 75°C, acrylic acid is 2%～4%(mass concentration), acrylamide is 2%～4%(mass concentration) and initiator is 0.7%～0.8%(mass concentration).
