摘要:

采用转矩流变仪熔融共混制备了新型乙烯⁃丙烯酸丁酯共聚物(EBA)/导电炭黑(CB)半导电屏蔽料,系统研究了不同比表面积、不同含量的乙炔炭黑ACB(G30和H140G)对高压电缆半导电屏蔽材料体积电阻率、力学性能及流动性能的影响。通过扫描电子显微镜分析了ACB和炉法炭黑(CCB)在EBA基体中的分散情况。并对两种CB制备的电缆屏蔽料进行性能对比。结果表明,当G30和H140G添加量均为35 %时复合材料的体积电阻率最低,分别为21.89 Ω·cm和7.86 Ω·cm,相比EBA/CCB复合材料而言,EBA/ACB复合材料有着更加优越的导电性能。

Abstract:

A novel semi⁃conductive shielding material for high⁃voltage cables was prepared with ethylene⁃butyl acrylate copolymer (EBA) as matrix and carbon black (CB) as a conductive material via melt blending using a torque rheometer. This study systematically investigated the effects of acetylene carbon black (ACB) type (G30 and H140G, differing in specific surface area) and content on the volume resistivity, mechanical properties, and flow properties of the composites. The dispersion of ACB and furnace carbon black (CCB) within the EBA matrix was characterized by scanning electron microscopy, and a comparative analysis of the final material properties was conducted. Experimental results demonstrated that a 35 wt% loading of either ACB type yielded optimal volume resistivity, with values of 21.89 Ω·cm for G30 and 7.86 Ω·cm for H140G. Furthermore, the EBA/ACB composites exhibited significantly superior electrical conductivity compared to their EBA/CCB counterparts.
