摘　　要：研究华光炭黑用量对丁苯橡胶(SBR)复合材料性能的影响,并与炭黑N330进行对比。结果表明:与炭黑N330相比,华光炭黑具有中空结构、较大的比表面积和较高的结构性;相同用量华光炭黑填充SBR胶料的门尼粘度和拉伸强度较大,导电性能和导热性能较好。随着炭黑用量的增大,两种复合材料的物理性能、导电性能和导热性能均提高。当华光炭黑用量为15份时,华光炭黑/SBR复合材料已成为导电材料。The effect of addition level of HG carbon black on the properties of SBR composites was investigated,and compared with carbon black N330. The results showed that,compared with N330, HG carbon black possessed hollow structure,larger specific area and higher structure. As the addition level of carbon black increased, the physical properties, electrical conductivity and thermal conductivity of SBR composites filled by either HG carbon black or N330 were improved. With the same addition level of carbon black,the Mooney viscosity and tensile strength of HG carbon black/SBR composites were higher, and the electrical conductivity and thermal conductivity were better. When the addition level of HG carbon black was 15 phr,the composite material became electrically conductive.
