Rubber composition suitable for automobile tires and its production |
| abstract |
A styrene/butadiene copolymer rubber to be used for automobile tires is lowered in its rolling resistance by blending it with carbon black and the following components (A) and (B):n (A) a dinitrodiamine compound represented by the following formula (I):n wherein X is a divalent organic group such as an alkylene, R¹ is hydrogen or an organic group such as an alkyl, provided that two nitrogen atoms linking through X may further link through R¹, and R² and R³ are each hydrogen or an alkyl, provided that R² and R³ may conjointly form a ring; and (B) a sulfide compound selected from dibenzothiazyl disulfide, tetralkylthiuram disulfide, and alkyl- or hydroxy-substituted phenol sulfide resin. The dinitrodiamine compound (A) and the sulfide compound (B) are added simultaneously to the rubber together with the carbon black in a first kneading step of a high temperature. The resulting rubber composition is lowered in its loss factor (tan δ) at around 60°C as compared with the case where the dinitrodiamine compound (A) is added alone, and it contributes to decrease the rolling resistance of tires made from the rubber composition. |
