摘要
采用加压差示扫描量热仪测定了聚脲脂的起始氧化温度和氧化诱导期,讨论了不同类型的抗氧剂对聚脲脂抗氧化性能的影响,通过阿雷尼乌斯经验式计算出聚脲脂的活化能,从化学动力学的角度评价了聚脲脂的氧化安定性。
The initiative oxidation temperature and oxidation induction time of polyurea grease were determined by pressure differential scanning calorimetry.The effects of different anti-oxidation agents on the properties of polyurea grease were discussed.The activation energy of polyurea grease was calculated by Arrhenius empirical formula,and the oxidation stability was evaluated from the view of chemical dynamics.
