摘要
通过对过氧化物硫化氢化丁腈橡胶(HNBR)在32#液压油中的高温加速老化试验,研究了HNBR材料性能随温度、时间的变化,并对该材料的贮存寿命进行预测。结果表明,该胶料制备的密封圈经模拟使用工况老化验证,使用寿命可达13年,满足用户使用要求。
The change of HNBR material properties with temperature and time was studied by the high temperature accelerated aging experiment of peroxide HNBR in 32# hydraulic oil,and the storage life of the material was predicted.The results showed that the sealing ring prepared by the compound had 13-year service life and verified by simulated working conditions.It met the requirements of users.
