铜粉在氟醚橡胶中作用的研究

Effect of copper powder in the fluorother compound

研究了氟醚橡胶中填加铜粉后对其性能特别是耐热性的影响 ,并对胶料的硫化行为进行了分析。结果表明 :氟醚橡胶中加入铜粉后 ,摩擦系数大幅度降低 ,但铜粉的加入加速了胶料老化速度 ;XPS分析表明 :铜粉使氟醚橡胶的硫化交联以离子加成的方式为主。

It introduced the effects of copper powder(Cu) on the physical properties,such as the heat resistance property and vulcanization behavior of fluoroether compound.The results showed that the rubber with Cu manifested lower abrasion coefficient,Cu accelerated the heat ageing course of the researched rubber,and XPS analysis proved the vulcanization is dominated by the iron addition.
