| Abstract: |
| The heat oxygen aging property and ozone aging property of clay/SBR and clay/NR nano-composites were studied，and the thermogravimetry and air isolation of clay/SBR nano-composite were also investigated.The results showed that both the heat oxygen aging property and the ozone aging property of clay/SBR nano-composite were superior to those of black/SBR composite；the heat oxygen aging property of clay/NR nano-composite was somewhat better than that of black/NR composite，but their ozone aging properties were similar to each other；and the uniformly dispersed nano-clay could improve the heat stability and air isolation of rubber，decrease the diffusion of oxygen and ozone in rubber，and reduce the probability of the attack at the molecular chain of rubber resulting in the improvement of heat oxygen aging property and ozone aging proper of rubber. |
