Abstract
Epoxy-Acrylate emulsion was synthesized by pre-emulsifying method,the property of its film is analysed by IR,the optimum formulation and process optimization were investigated.It was found that the epoxy-acrylate emulsion has excellent and stable comprehensive performance and high conversion rate accord with GB/T 20623-2006 when using pre-emulsifying method,the optimum formula is epoxy resin in E-44 of 5.48%,the KH-570 is 4.38%,the acrylate is 23.3%,the appropritate rate of OP-10 and SLS is 2/1,the right amount of emulsifier is 0.66%,grease-water proportion is 1/2,the water is 65.8%,the NaHCO3 is 0.16%,0.22% initiator,polymerization temperature is 80 ℃.
