A rubber composition comprising 100 parts by weight of a rubber ingredient comprising natural rubber and/or a synthetic rubber, 0.1 to 50 parts by weight of at least one nitrogenous compound selected among benzimidazole derivatives having a specific structure and hydrazide derivatives having a specific structure, and 0.1 to 50 parts by weight of a protonic acid; and a pneumatic tire including a member formed from this rubber composition. The rubber composition enables excellent gripping performance while attaining intact productivity. The pneumatic tire produced from this rubber composition, in particular, the tire whose tread has been formed from the composition, has significantly improved gripping performance in high-speed driving, etc.
一种橡胶组合物,按重量计包含 100 份由天然橡胶和/或合成橡胶组成的橡胶成分、0.1 至 50 份按重量计从具有特定结构的苯并咪唑衍生物和具有特定结构的酰肼衍生物中选出的至少一种含氮化合物,以及 0.1 至 50 份按重量计的质子酸;以及一种充气轮胎,包括由该橡胶组合物形成的部件。该橡胶组合物可实现优异的抓取性能,同时达到完整的生产率。用这种橡胶组合物生产的充气轮胎,特别是用这种组合物形成胎面的轮胎,在高速行驶等情况下具有显著改善的抓地性能。
