【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。更多还原

【Abstract】 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.更多还原
