摘要
研究填料对天然橡胶/溴化丁基橡胶高阻尼橡胶物理性能及阻尼性能稳定性的影响。结果表明:填料用量一定时,仅用炭黑N330填充的高阻尼橡胶物理性能最优,但耐热氧老化性能最差;采用云母粉替代部分炭黑N330制备的高阻尼橡胶物理性能略有下降,热氧老化后物理性能和阻尼性能变化率最小,耐热氧老化性能最佳;木质素替代部分炭黑N330填充的高阻尼橡胶耐热氧老化性能介于两者之间。
The effects of different fillers on the physical properties and damping performance of high damping natural rubber/brominated butyl rubber blend were studied. The results showed that the physical properties of high damping rubber filled with carbon black N330 were the best,but the thermal oxidation resistance was the worst. When part of the carbon black was replaced by mica powder,the physical properties of high damping rubber decreased slightly,but the physical properties and damping performance after the thermal oxidation aging were improved,and the thermal oxidation aging resistance was the best. The thermal oxidation resistance of high damping rubber could also be improved by using lignin to replace part of carbon black,but it didn＇t reach the same performance level by using mica.
