CARBON BLACK, RUBBER COMPOSITION AND PNEUMATIC TIRE |
| 摘要 |
The present invention provides carbon black, the standard deviation σ of aggregate size distribution of which is obtained by alight scattering method using an ultraviolet ray, the standard deviation σ satisfying the expression (1): σ<−48.7×(24M4DBP/Dst)+161.8 (1). In the expression (1), 24M4DBP represents the dibutyl phthalate absorption number (cm3/100 g) of compressed sample, and Dst (nm) is a Stokes' equivalent diameter providing the mode in aggregate size distribution obtained by a centrifugal sedimentation method. The carbon black can improve both the abrasion resistance and the low rolling resistance of a tire. The present invention also provides a rubber composition mixed with this carbon black, and a pneumatic tire including a tread part formed by using this rubber composition. |

1. Carbon black, the standard deviation σ of aggregate size distribution of which is obtained by a light scattering method using an ultraviolet ray, the standard deviation σ satisfying the expression (1):
σ<−48.7×(24M4DBP/Dst)+161.8 (1) wherein 24M4 DBP represents the dibutyl phthalate absorption number (cm3/100 g) of compressed sample, and Dst (nm) is a Stokes' equivalent diameter providing the mode in aggregate size distribution obtained by a centrifugal sedimentation method. |
