摘要
为了解氟橡胶密封件在液压系统中的贮存寿命,在两种介质环境中对氟橡胶开展了加速老化试验。结果表明,氟橡胶耐热、耐介质、耐老化性能优异,在90℃下加速老化120 d后,压缩回弹性能、物理力学性能保持率均在80%以上,评估其具有20年的贮存寿命。
In order to solve the storage life of the fluoroelastomer seal in the hydraulic system,the accelerated aging test was carried out on two kinds of medium environment.The results show that the fluoroelastomer has good dielectric resistance and aging resistance.Accelerated aging 120 days under 90℃,compression rebond and mechanical properties to keep rates are above 80%.The storage life of fluoroelastomer is estimated to 20 years in the hydraulic system.
