摘　　要：以氢化苯乙烯-丁二烯-苯乙烯嵌段共聚物(SEBS)、聚丙烯为原料,通过熔融共混方法制备抗静电热塑性弹性体(TPE),研究油种类、永久型抗静电剂聚醚酰胺和相容剂SEBS-g-MAH用量对TPE抗静电性能和拉伸强度的影响,并对耐水洗性能进行测试。结果表明:当环烷油KN4006用量为70份、聚醚酰胺用量为22份、相容剂用量为7份时,TPE的抗静电性能最好,拉伸强度较高,水洗擦拭后抗静电稳定性优异。Antistatic thermoplastic elastomer(TPE) was prepared by melt blending of hydrogenated styrene-butadiene-styrene block copolymer(SEBS) and polypropylene,and the effects of the kind of oil,the amount of permanent antistatic agent poly(ether-block-amide) and compatibilizer SEBS-g-MAH on the antistatic property and tensile strength of TPE were studied. The results showed that when the amounts of naphthenic oil KN4006,poly(ether-block-amide) and compatibilizer were 70,22 and 7 phr respectively,the antistatic property was the best,the tensile strength was high,and the antistatic stability after washing and wiping was excellent.
