摘　　要：研究了环氧树脂改性苯丙乳液的合成工艺以及乳化剂、引发剂、环氧树脂、功能单体用量等条件对反应过程及乳液性能的影响。通过实验得到阴离子与非离子乳化剂配比为1.5:1、引发剂的用量为0.6%、功能单体MAA的用量为2%、环氧树脂的用量为5%。合成的环氧改性苯丙乳液,在耐水性、耐碱性、Ca2+稳定性方面有了明显提高。The emulsion of styrene acrylic ester with epoxy resin was prepared and characterized. The factors of effect on emulsion copolymerization, such as composition of emulsifier, amount of initiator, amount of epoxy resin, amount of functional monomer, were studied. The best formulation condition of modified styrene-acrylic emulsion could be obtained when the radio of surfactants was 1.5 ： 1 ,the content of initiator was 0. 6%, the content of MAA was 2%, the content of epoxy resin was 5%. The styrene-acrylic emulsion modified by epoxy resin possessed higher waterproof ability, baseproof ability, Ca2＋ stability compared to the pure styrene-acrylic emulsion.
