摘要
采用动态硫化法制备了ＮＢＲ／ＰＦＰＡ热塑性弹性体（ＴＰＥ），并重点讨论了ＮＢＲ／ＰＦＰＡ质量配比、填料和增塑剂对热塑性弹性体的拉伸强度、扯断伸长率、耐磨性和硬度等力学性能的影响。结果表明，ＮＢＲ／ＰＦＰＡ质量配比为８５／１５～７０／３０、ＨＡＦ和邻苯二甲酸二丁酯分别为填料和增塑剂时，可获得性能优异的热塑性弹性体。
A series of thermoplastic elastomer were prepared by dynamic vulcanization method. The relationship between blend ratio(NBR/PFPA), filler, plasticizer and mechnaical properties, such as abrasion resistance, tensile strength, elongation at break, were studied. The results show that when blend ratio is in the range of 85/15￣70/30(NBR/PFPA), HAF as filler , dibutyl phthalate as plasticizer, the thermoplastic elastomer with excellent mechanical properties can be obtained.
