摘　　要：以导电石墨烯和导电炭黑为功能填料,以丁腈橡胶(NBR)为基胶,制备出导电性能较好的导电橡胶材料。以导电石墨烯为变量设计了6种不同的组分,开展了复合材料塑性、硫化性能、基本性能、力学性能、老化性能、高温性能性能、导电性能和电磁屏蔽效能实验,探究了加入导电石墨烯对导电炭黑/丁腈橡胶复合材料性能的影响规律。结果表明,在导电炭黑/丁腈橡胶复合材料中加入导电石墨烯,可提高复合材料的导电性,使之作为导电橡胶使用,如填充3份以上(质量份)石墨烯,材料具有一定的电磁屏蔽功能;也能降低复合材料的硫化时间,降低生产成本;导电石墨烯的添加对丁腈橡胶复合材料的热氧老化性能影响较大,但对高温性能影响较小;另外,导电石墨烯的添加会降低复合材料的力学性能,拉伸强度和撕裂强度降低率分别为7%和7.4%。在后续的研究中,将针对导电石墨烯在橡胶中的分散情况进行研究,改善其与橡胶材料的相容性。Conductive rubber materials with better conductive properties were prepared using conductive graphite and carbon black as functional fillers and nitrile butadiene rubber(NBR)as the base.Six different components were designed with conductive graphene as variables,and experiments were conducted to test the plasticity,vulcanization properties,basic properties,mechanical properties,aging properties,high-temperature properties,electrical conductivity,and electromagnetic shielding effectiveness of the composites.The effect of conductive graphene on the properties of conductive carbon black/NBR composites was investigated,and the results showed that adding conductive graphene into a conductive carbon black/NBR composite could improve the conductivity and reduce the curing time of the composite.The addition of conductive graphene has a significant effect on the aging properties of rubber compounds but has little effect on the high-temperature properties.In addition,the addition of conductive graphene can reduce the mechanical properties of the rubber compound,but the effect is small;the reduction rates of the tensile strength and tear strength are 7%and 7.4%,respectively.In the subsequent research,the dispersion of conductive graphene in rubber will be studied to improve its compatibility with rubber materials.
