摘要
采用加速老化试验方法对ZN-1阻尼橡胶材料的热氧老化性能进行了研究,获得了不同老化温度及老化时间对硅橡胶泡沫材料力学性能及阻尼性能的影响规律。研究结果表明,随着老化温度的升高及老化时间的延长,ZN-1的拉伸强度出现了先下降后升高的现象,而扯断伸长率则表现为单调下降的趋势。同时,还研究了ZN-1阻尼橡胶材料在热氧老化条件下微观结构与性能变化之间的关系,得到了ZN-1阻尼橡胶材料的热老化机理。
The thermal-oxydative ageing properties of ZN-1 damping rubber materials were investigated by using accelerated ageing test, then the relations between different ageing temperatures and ageing time and mechanical properties and damping properties of ZN-1 damping rubber materials were obtained. The results showed that with increasing ageing temperature and time, the tensile strength of ZN-I damping rubber materials firstly decreases to a certain value and then increases; the tensile elongation of ZN- 1 damping rubber materials decreased. Finally, the ageing mechanisms of ZN-1 damping rubber materials were deduced from some analyses of the relation between macroscopical properties and microstructure.
