| Abstract: | In this paper,the thermal-oxydative ageing properties of silicone rubber foam materials were investigated by using accelerated ageing test,then the relations between different ageing temperature and ageing time and compression mechanical properties of silicone rubber foam materials were obtained.Finally,the ageing mechanisms of silicone rubber foam materials were deduced from some analyses,not only the molecule chain structure changes of silicone rubber during thermal-oxydative process,but also the cellular structure changes of silicone rubber foam materials under compression states. |
