摘　　要：由于橡胶材料的绝缘性好,容易产生静电,而在很多的工作环境中,产生静电导致的危害是致命的。所以,主要研究了超导炭黑HG-1B的添加量的改变对NBR的抗静电性能及其物理机械性能的影响,并与不掺加超导炭黑的NBR做对比。结果表明:超导炭黑能够很好的改善NBR性能,而且随着超导炭黑添加量的不断增加,丁腈橡胶的表面平滑度增加,NBR的抗拉强度、300%定伸应力不断增加,而且均大于不加超导炭黑的空白实验对照组,硬度也是逐渐增加。老化实验前的拉伸强度、扯断伸长率和300%定伸应力都比老化后要好。而抗静电性能也是随着炭黑添加量的增加而增加,变化的幅度较大。老化前的电阻、体积电阻优于老化后的。Due to the good insulation of rubber materials, it is easy to generate static electricity. However, the damage caused by static electricity is fatal in many working environments. Therefore, this paper mainly studies the effect of the change of the addition amount of superconducting carbon black HG-1 B on the antistatic property and physical and mechanical properties of NBR, and compared it with NBR without superconducting carbon black. The results show that superconducting carbon black can improve the performance of NBR, and the surface smoothness of nitrile rubber increases with the increase of superconducting carbon black. The tensile strength and 300% modulus of NBR increase continuously, and the elongation at break was greater than that of the blank experimental control group without superconducting carbon black. The hardness was also gradually increased. The tensile strength, the elongation at break, and the 300% modulus before the aging test were better than those after aging. The antistatic property also increased with the increase of carbon black, and the variation range was large. The resistance, volume resistance and antistatic properties before aging were better than those after aging.
