氧化石墨烯在悬置橡胶中的应用性能研究
|
摘要
采用硅烷偶联剂KH550对氧化石墨烯(GO)进行改性,制备改性GO填充的悬置橡胶复合材料,并对其性能进行研究。结果表明:与未加GO的胶料相比,加入GO的混炼胶的焦烧时间和正硫化时间延长,填料分散性改善,同时填料网络结构增强;复合材料的300%定伸应力和耐疲劳性能提高。
The graphene oxide(GO) was modified by silane coupling agent KH550,the modified GO filled suspension rubber composites were prepared,and their properties were investigated. The results showed that,compared with the compound without GO,the scorch time and optimum cure time of the compound were extended,the dispersion of filler was improved,and the filler network structure was enhanced. The modulus at 300% elongation and the fatigue resistance of the composites were improved with addition of GO.
