Study on Structure and Properties of SBR Nanocomposite Filled with HG Carbon Black

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.
