摘　　要：根据6种橡胶密封材料的加速老化试验数据和自然贮存数据,分别计算出加速系数,并对加速温度之间的加速系数进行了研究。结果表明:除氟橡胶外,橡胶密封材料的加速系数符合范德霍夫规则,即加速系数在2～4内。在无自然贮存数据的情况下,整机加速试验采用加速温度之间的加速系数作为橡胶密封材料的加速系数更接近于实际情况。Based on the data for accelerated life and natural storage life of six rubber sealing materials including EPDM-8101, EPDM-8106, NBR-45713, NBR-5073, FKM-7103 and CR-4103, the accelerated factors were calculated. The results indicate that excent FKM-7103, the accelerated factors are agree with Van＇Hoff factor. The accelerated factors of aging temperature can be used to predict storage life of rubber sealing materials instead of the ac-celerated factors between accelerated life and natural storage life.
