氧化还原引发聚合丙烯酸酯乳液及胶粘剂的研究

Study on redox initiators in acrylic emulsion polymerization and adhesive

主要探讨了氧化还原引发剂用量对聚合反应速度、单体转化率的影响。同时对乳化剂用量,湿润剂种类用量,增粘乳液对乳液胶粘剂的性能的影响也进行了分析。研究发现:适宜的氧化还原引发体系的用量在单体的0．3％-0．8％之间;复合乳化剂用量为总量的2％-4％之间;LSR-101湿润剂为单体总量的0．5％-1．7％;增粘乳液用星为25％时,可得到转化率高,粘接性能良好的胶粘剂。

In this paper,the influences of amounts of redox initiators on polymerization rate,monomer conversion and were discussded. At the same time,the amounts of emulsitier,the kind of wetter and the tackitiers were analyzed on the properties of acrylic emulsion adhesive. When 0.3 to 0.8% initiator,2 to 4% mixture emulsifier,0.5 to 1.7% wetter and 25% tackifier,the acrylic emulsion adhesive of high monomer conversion and good adhesion was received.
