摘要
研究炭黑和碳纳米管对常温和高温下丁腈橡胶(NBR)物理性能和耐热空气老化性能的影响。结果表明,增大炭黑用量或加入碳纳米管,胶料的Payne效应增强,加工性能降低,常温下硫化胶的耐热空气老化性能变化不大;与常温相比,高温下硫化胶的物理性能和耐热空气老化性能显著降低。
The effect of carbon black and carbon nanotubes on the physical properties and hot air aging resistance of NBR at normal temperature and high temperature was investigated. The results showed that,with increased addition level of carbon black or addition of carbon nanotubes,the Payne effect of the compound was strengthened and the processability was decreased,but the hot air aging resistance of the vulcanizate at normal temperature changed little. However, the physical properties and the hot air aging resistance of the vulcanizate at high temperature were reduced significantly.
