摘要
本文从开发ＮＲ系热塑性弹性体的角度出发，采用动态硫化技术，以ＮＲ＋ＨＤＰＥ为基本体系，分别应用了过氧化物及硫黄两种不同的交联体系，在１４０—１８０℃下用Ｂｒａｂｅｎｄｅｒ塑化仪进行共混，制得了具有不同物理性能的共混体。通过改变不同并用比、交联剂用量、加料顺序等，初步探讨了制造ＴＰＥ的共祝条件、配方。并对动态硫化的程度、共混体的耐热空气老化性能、加工性能和返炼性能进行了研究。
The paper states the blend having difffrent phsical properties, which is made in blending way by brabender plasticorder under 140-180℃, based on developing NR system elastomer respect,adopting dynamic curing technique, using NR+HDPE as basic system, and DCP & sulphur two different corss-linking system respestivity, It explores the blending condition, recipe of making TPE primarily, through changing different blending ratio, cross - linking additive dose, filling material procedure etc, and make study to the dynamic curing level, hat air resistant aging properties, processability and re-run properties of the blend.
