摘要
列举了大量橡胶及其制品的烘箱加速老化及室内自然老化的试验数据，表明根据橡胶及其制品的加速老化结果预测贮存期和使用寿命与实测结果是吻合的，贮存期快速测定方法是可靠的。同时列举了预测与实测结果偏差较大的几个实例，其主要原因是：相对湿度、物理松弛和溶胀等造成加速老化与自然老化的机理不同。其中相对湿度引起的偏差是无法避免的，因此基于热氧老化机理的贮存期快速测定方法还有一定缺陷。
A lot of data from the oven accelerated aging test and the natural aging test on the rubbers and their products were analysed.The results showed that the predicted storage life and service life of rubbers and their products with the accelerated test were in accordance with the measured ones,and the accelerated determination of the storage life was practicable.Several exceptional cases with larger differences between the predicted result and measured one were give.It was attributed to the different mechanisms between the accelerated aging and natural aging caused by relative humidity, physical relexation and swelling et.The difference resulted from the relative humidity was unavoidable.Therefore the accelerated determination of the storage life based on the thermal oxidative aging mechanism had a definite drawback.
