摘要
以丁腈橡胶O形橡胶密封圈(简称橡胶O形圈)为例,提出加速老化法预估橡胶O形圈的寿命的一种新方法.以压缩应力松弛性能保持率为预估指标,分别在80,100,110和120℃下对橡胶O形圈进行压缩应力松弛试验,先推算出橡胶O形圈贮存3,5,10,15和20年的压缩应力松弛性能保持率,再推算出在80和100℃下橡胶O形圈贮存3,5,10,15和20年所需的加速老化时间.
Abstract
Taking nitrile rubber O-shaped sealing ring(referred to as rubber O-shaped ring)as an example,a new method for life prediction of the rubber O-shaped ring by accelerated aging was proposed.Using the compression stress relaxation performance retention rate as the index for predicting the storage life,the compression stress relaxation tests of the rubber O-shaped ring were conducted at 80,100,110 and 120℃,respectively.The compression stress relaxation retention rates of the rubber O-shaped ring stored for 3,5,10,15 and 20 years were firstly calculated,and then the acceleration aging time required for the rubber O-shaped ring stored for 3,5,10,15 and 20 years at 80 and 100℃ was calculated.
