对硅橡胶泡沫材料进行了45%应变压缩状态下的热老化试验研究。结果表明,硅橡胶泡沫材料的永久变形量随着老化条件严酷程度的增加而增加。硅橡胶泡沫材料加载高温老化会使其损耗峰降低,玻璃化温度向高温区域移动。
The heat aging test of silicone rubber foam at 45% strain was carried out. The results show that the permanent deformation of silicone rubber foam increases with the severity of aging conditions. Silicone rubber foam loaded with high temperature aging will reduce the loss peak, the glass transition temperature to high temperature area.
