摘　　要：采用废弃EPS泡沫塑料取代部分苯乙烯(St)单体制备苯丙乳液,研究废弃EPS泡沫塑料掺量对苯丙乳液性能的影响。结果表明:当废弃EPS泡沫塑料掺量为30%时,苯丙乳液的稳定性较好、180 min时的转化率为88.2%、凝胶率为5.2%、平均粒径为0.48μm,且粒径分布集中。通过红外图谱分析得出,St、BA、AA都参与了聚合反应,废弃EPS泡沫塑料的加入对合成苯丙乳液的结构组成改变不大。This paper adopted the wasted EPS foam to substitute part of styrene （St） to synthesize styrene-acrylic emulsion, studied the effect of EPS foam content on performance of styrene-acrylic emulsion. The results showed when the amounts of the wasted EPS foam is 30%,the mechanical stability is better, the conversion rate is 88.2% with 180min, gelration rate is 5.2%,average particle size is 0.48 μm. Infrared spectrum results showed that incorporation of EPS did not change the chemical composition of the styrene-acrylic emulsion,and styrene,butyl acrylate,acrylic acid are all involved in the polymerization reaction.
