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.
