非炭黑填料对EPDM硫化动力学影响的研究

Study on the influence of the non-carbon black on EPDM vulcanization dynamics

探讨了滑石粉、陶土、碳酸钙、白炭黑对EPDM的反应过程与动力学参数硫化反应级数(n)、硫化反应表观速度常数(k2)、诱导时间(td)之间的关系,研究了不同硫化体系和温度等因素对碳酸钙填充的胶料动力学参数的影响。

This article has mainly discussed talcum powder, pottery clay, calcium carbonate, white carbon black on the EPDM reaction process and dynamics parameter curing order of reaction n, curing response apparent rate constant k2, the induction time td relations. Meanwhile, effect of curing system and temperature on dynamics parameter of sizing material were researched.
