Abstract:
      Through appearance observation，surface element analysis，thermogravimetric analysis，density determination and organic component detection of pyrolysis gas chromatography-mass spectrometry，the cause of cracking failure of natural rubber（NR） bushing for automobile was analyzed.The results showed that the cracking of the NR bushing for automobile was caused by thermo-oxidative aging.Compared with the sample without cracking，the surface oxygen element content of the cracked sample increased，the thermal decomposition temperature increased，the density increased，and the phenolic antioxidant was disappeared.
