| 本文利用扫描电镜SEM和橡胶加工分析仪(RPA-2000)设备,研究了不同白炭黑用量的NBR/BR并用胶的动态性能和微观形貌。结果表明：随着白炭黑用量的增大,白炭黑聚集体增多,白炭黑与橡胶基体间的相互作用增大,混炼胶的Payne效应增大。动态性能方面,随温度升高,NBR/BR混炼胶损耗因子先增大后减小;随白炭黑用量增大,NBR/BR混炼胶损耗因子在低温时增大,高温时减小；随温度升高, NBR/BR硫化胶储能模量G’变化不大,损耗因子减小。随白炭黑用量增大,NBR/BR硫化胶储能模量G’增大,损耗因子增大；随着温度的升高,NBR/BR硫化胶的损耗因子先增大后减小。 |
| 英文摘要: |
| In this paper, the dynamic properties and it were studied microstructure of NBR / BR with different silica by scanning electron microscopy (SEM) and rubber processing analyzer (RPA-2000). The results showed that with the increase of the amount of silica, the aggregation of silica increased, the interaction between silica and rubber matrix increased, and the Payne effect of the compound increased. Dynamic performance, with the temperature rising , NBR / BR compound loss factor increased first and then reduced; With the increasing in the amount of silica, NBR / BR compound loss factor increased at low temperature, high temperature decreased. With the increase of temperature, NBR / BR vulcanized rubber storage modulus G " hadn’t changed , loss factor decreased . With the advancing in the amount of silica, NBR / BR vulcanized rubber storage modulus G " increased, loss factor increased. As the temperature increasing , the loss factor of NBR / BR vulcanizate increased firstly and then decreased . |
