摘要
研究了SBS(苯乙烯─丁二烯─苯乙烯嵌段共聚物)及SBS/CPE(氯化聚乙烯)共混体系的流变学行为。探讨了不同类型的SBS,SBS/CPE比例、CPE含氯量、增粘剂和增塑剂的含量等因素对粘接性能的影响。结果表明:SBS/CPE共混体系对PVC人造革的粘接有正协同效应,并可以得到熔融粘度比SBS小、而粘接力比SBS大的热熔性压敏胶粘剂。
In this paper, the rheological behavior of SBS adhesive and CPE/SBS blend system were studied. The influences of the kinds of SBS, CPE/SBS proportion, the content of chloride in CPE, the quantity of hyperadhesion agent and plastifying agent on adhesivity were discussed. The results showed that the adhesion strength of CPE/SBS blend system had significant positive departure for PVC leatherette. And a pressure-sensibility thermosol with viscosity lower than SBS,adhesivity higher than SBS was obtained.
