摘要

高耐久丁腈橡胶(NBR)复合材料对于相关电力设备长时间的安全运营具有重要的意义，目前传统的纳米球形粒子增强的NBR复合材料的微观结构和综合性能难以满足耐久性的要求。因此，本文采用绿色水相复合技术，将水分散性优异的氧化石墨烯(GO)引入到NBR胶乳中，获得了良好分散的GO/NBR母胶，进一步与其他组分复合制备得到了片层填料GO和球形纳米填料炭黑(CB)共同增强的NBR复合材料。结果显示，和传统炭黑以及片状高岭土增强的NBR相比，GO的引入增强了纳米填料网络，同时增强了与NBR橡胶分子链的作用，增加了交联密度。在GO含量仅2份时，复合材料的定伸强度和拉伸强度均高于炭黑和高岭土增强体系。最为重要的耐久性能显示，相比传统炭黑体系，GO增强体系的裂纹扩展速率降低了26.0%，临界撕裂能提升了31.6%。

Abstract

High-durability nitrile butadiene rubber (NBR) composites are crucial for the long-term safe operation of related electrical equipment. However

the microstructure and comprehensive properties of traditional NBR composites reinforced with nanospherical particles do not meet the durability requirements. Therefore

this study employed a green aqueous compounding technology to introduce graphene oxide (GO) with excellent water dispersibility into NBR latex. This yielded a well-dispersed GO/NBR masterbatch

which was further compounded with other components to prepare NBR composites co-reinforced by the lamellar filler GO and the spherical nanofiller carbon black. Compared to traditional carbon black and lamellar kaolin clay

GO enhanced the nanofiller network

strengthened the interaction with NBR rubber molecular chains

and increased the crosslink density. At a GO content of only 2 phr (parts per hundred rubber)

the modulus and tensile strength of the composites were higher than those of systems reinforced with carbon black or kaolin clay. Most importantly

the crack growth rate of the GO-reinforced NBR composite was reduced by 26.0%

and the critical tear energy was increased by 31.6%

compared to the traditional carbon black reinforced NBR composites.
