纳米白炭黑的表面改性及其在氯丁橡胶中的应用

Surface Modification of the Nano-silica and Its Application in Neoprene

研究纳米白炭黑经硅烷偶联剂(Si-75)湿法改性后对氯丁橡胶抗疲劳性能的影响,并对改性剂的用量、改性工艺条件进行了优化。实验结果表明:适当改性后的纳米白炭黑可显著提高氯丁橡胶的抗撕裂和抗疲劳性能。

The effect of the modified nano-silica on the neoprene is investigated, the amount of coupling agent and modification conditions are also optimized. As the results showed, the modified nano-silica can markedly improve the tear strength and fatigue life on the neoprene.
