Rubber composition for tire |
摘要 |
The present technology provides a rubber composition comprising from 30 to 100 parts by weight of a carbon black, and from 10 to 80 parts by weight of an inorganic filler per 100 parts by weight of a diene rubber, wherein the inorganic filler has from 20 to 80% particles of a particle size of at most 5 μm; and when an aluminum content in the inorganic filler is defined as Wal wt. % and a silicon content is defined as Wsi wt. %, the aluminum content Wal is from 11 to 40 wt. %, and a ratio Wal/(Wal+Wsi)×100 of aluminum to a total of aluminum and silicon is from 15 to 38 wt. %. |

1. A rubber composition for a tire comprising from 30 to 100 parts by weight of a carbon black, and from 10 to 80 parts by weight of an inorganic filler per 100 parts by weight of a diene rubber, wherein the inorganic filler has from 20 to 80% particles having a particle size of at most 5μm; and when an aluminum content in the inorganic filler is defined as Wal wt. % and a silicon content is defined as Wsi wt. %, the aluminum content Wal is from 11 to 40 wt. %, and a ratio Wal/(Wal +Wsi) ×100 of aluminum to a total of aluminum and silicon is from 15 to 38 wt. %;
wherein a nitrogen adsorption specific surface area of the carbon black is from 15 to 40 m2/g, and a DBP absorption is from 50 to 120 mL/100 g. |
