橡胶密封件加速老化试验影响因素分析及验证

摘要

The common accelerated aging methods for rubber materials do not consider the detailed factors of engineering applications, such as intial compressing rate, types of seal, seal medium and so on. By means of a series of comparison testing, effects of the above mentioned detailed factors on tests of rubber accelerated aging were obtained. The purpose was to provide scientific basis for assessing storage life of equipments with rubber seal material.%　　通用的橡胶材料加速老化试验方法未考虑初始压缩率、密封形式、密封介质等工程应用的细节因素。通过一系列对比试验，初步掌握了上述各因素对橡胶密封件加速老化试验结论的影响程度，为工程实践中科学评估装备贮存寿命提供了依据。
