摘要
研究天然橡胶(NR)/炭黑、NR/白炭黑、异戊橡胶(IR)/白炭黑混炼胶的结合橡胶含量和Payne效应。结果表明:随着二段混炼胶停放时间延长,炭黑混炼胶的结合橡胶含量增大,Payne效应增强,硫化胶应力应变性能和动态性能等变化不明显;白炭黑混炼胶的结合橡胶含量增大,Payne效应基本不变,硫化胶定伸应力明显提高,动态性能有一定程度改善;白炭黑混炼胶的结合橡胶含量明显大于炭黑混炼胶。
The bound rubber content and Payne effect of natural rubber （NR）/carbon black,NR/silica, polyisoprene rubber （IR） /silica compounds were studied. The results showed that with the storage time of two-stage mixed compound prolonging, the bound rubber content of carbon black filled compound increased, Payne effect increased, and the stress-strain properties and dynamic properties of the vulcanized rubber changed little. For the silica filled compounds, after the storage of mixed compound, the bound rubber content increased, Payne effect didn＇ t show any change, the modulus of the dynamic properties was improved. In general, the bound rubber content higher than that of carbon black filled compound. vulcanized rubber increased and the of silica filled compound was much
