SBS/LDPE共混型热塑性弹性体的性能研究(Ⅱ)

Study on the Properties of SBS/LDPE Blending Thermoplastic Elastomer(Ⅱ)

选用苯乙烯-丁二烯-苯乙烯弹体(SBS)和低密度聚乙烯(LDPE)为主体材料,采用部分动态硫化法制备了一类性能良好的材料———SBS LDPE共混型热塑性弹性体(TPE),具有力学强度高,断裂伸长率大,可重复加工等特点,并研究了共混方法、硫化温度、硫化时间等工艺方面因素对动态硫化SBS LDPE热塑性弹性体力学性能的影响。

The thermoplastic elastomer from SBS/LDPE blend with excellent mechanical properties,such as high mechanical strength and elongation at break and repeatable processability was prepared by partial dynamic vulcanization.The influences of such technologies as blending methods,temperature and time of dynamic vulcanizationon the mechanical properties of SBS/LDPE blending thermoplastic elastomer were studied.
