| Abstract: |
| The antioxidant system of rubber gasket in CRH2046A EMU was studied，different antioxidants were tested in the rubber gasket formula by using hot air accelerated aging experiment，and then the service life of the rubber gasket was predicted using mathematical statistics model.The results showed that，compared with 1.5 phr antioxidant 4010 alone，the combination of antioxidant 4010 and antioxidant RD by a blending ratio of 1/0.5 could greatly improve the service life of the rubber gasket. |
