摘　　要：采用4种不同的混炼工艺制备炭黑填充天然橡胶(NR)/反式1,4-聚异戊二烯(TPI)并用胶,并对其性能进行对比研究。结果表明:采用在常温下加入炭黑和配合剂、高温下加入硫黄和促进剂的混炼工艺制备的NR/TPI并用胶加工安全性、综合物理性能和减震性能较好,动态生热较低。The carbon black filled NR/TPI blends were prepared by four different mixing proces- ses,and their properties were investigated. The results showed that, the NR/TPI blend, which was prepared by adding carbon black and compounding agents at room temperature, and adding sulfur and accelerator at high temperature, possessed better processing safety, comprehensive physical property and damping performance, and had lower dynamic heat build-up.
