The effects of maleic anhydride grafted POE, copper oxidation inhibitor, hindered phenolic antioxidants 1010/ 1098 and compounded phosphate antilxidant 626 on the thermal oxidative aging properties of toughening polyamide 6 were studied separately , and the effects of oxidations and aging time on the mechanical properties of polyamide 6 were studied. Experiment results provided that the proper oxidation with polyamide 6 could keep mechanical properties at the rate of 90% above in condition of temperature 160℃ and thermal oxidative for 24 h, and the material could meet requirements of fuel tubes system of automobile.
