橡胶组合物具有基础母体混合物,所述基础母体混合物包含二烯橡胶和固体聚结材料,所述固体聚结材料包含由碳纳米管的连续网络组成的解聚碳纳米管,所述连续网络包含1)空隙和2)d50平均尺寸小于5μm的碳纳米管的聚集体,所述空隙和所述聚集体一起的量小于预定表面积的60%,此类百分比如通过电子显微术图像分析所测定,其余部分为所述连续网络中的所述解聚碳纳米管,所述解聚碳纳米管不包含明确定义的形状且其量为所述预定表面积的至少40%,其中所述基础母体混合物的最小门尼粘度ML(1+4)100为至少85MU;以及固化系统。

    Methods for producing a cross-linkable rubber composition that comprises a masterbatch are disclosed. The masterbatch comprising a base masterbatch and the method includes forming the base masterbatch by adding a diene rubber to an internal mixer; adding a total quantity of a solid agglomerated material that includes carbon nanotubes into the mixing chamber; and mixing the diene elastomer and the solid agglomerated material. To ensure adequate distribution and dispersion of the material, the base masterbatch has a minimum Mooney viscosity ML(1+4)100 of at least 85 MU.
