| 摘 要： | 通过对氯丁橡胶在55℃、70℃、85℃、100℃下热空气加速老化的实验，研究了氯丁橡胶的老化机理并进行了寿命预测。红外分析结果说明氯丁橡胶的老化机理为：热氧老化在C=C上进行；85℃、]00℃侧基C1脱离主链。以扯断伸长率为指标进行寿命预测，可知氯丁橡胶在本实验条件下的贮存寿命约为20a。

| Abstract: | The thermal oxidative aging properties of neoprene at 55 ℃, 70 ℃, 85 ℃, 100 ℃ were determined by using accelerated aging method at laboratory. The aging mechanism of chloroprene rub- ber was determined by IR：thermal aging on the C = C;85 ℃ ,100 ℃ the side groups C1 was away from the main chain. The relationship between properties and aging time of neoprene was established, and predicted at 25 ℃ neoprene storage life is twenty years. |
