摘要:利用差示扫描量热(DSC)加速老化试验方法,以不同温度下测得的氧化诱导时间(OIT)为基础,建立温度–寿命相关的阿伦尼乌斯方程,并以此对不同温度下聚丙烯的寿命进行快速估算。结果表明,其估算结果有效,是筛选抗氧剂配方的一种较好的方法。
Arrhenius equation which showed the relationship between the oxidation induction time(OIT) and the aging temperature was established based on OIT measured under different temperature by using differential scanning calorimetry ( DSC ) accelerated aging test method, and the OIT of polypropylene at different temperature was quickly estimated by using Arrhenius equation. The results showed that the estimates based on Arrhenius equation was effective, which was a good method for screening antioxidant formula.
