Title (EN) RUBBER COMPOSITION FOR TREAD
(FR) COMPOSITION DE CAOUTCHOUC POUR BANDE DE ROULEMENT
(JA) トレッド用ゴム組成物
Abstract: front page image
(EN)Use of polybutadiene containing specific syndiotactic poly(1,2-butadiene) in a tread rubber can improve wearing resistance without impairing chipping/cutting resistance. A rubber composition for treads is provided which contains a rubber ingredient containing 10-30 wt.% butadiene rubber which contains syndiotactic poly(1,2-butadiene) dispersed therein having an average primary-particle diameter of 100 nm or smaller.
(FR)L'invention concerne l'utilisation de polybutadiène contenant du poly(1,2-butadiène) syndiotactique dans un caoutchouc d'une gomme de bande de roulement permettant d'améliorer la résistance à l'usure sans réduire la résistance à la coupure/fissure. L'invention concerne également une composition de caoutchouc pour bandes de roulement qui comprend un ingrédient de caoutchouc contenant 10-30 % en poids de caoutchouc de butadiène dans lequel a été dispersé du poly(1,2-butadiène) syndiotactique à diamètre moyen de particules primaires de 100nm ou moins.
(JA) 特定のシンジオタクチック-1,2-ポリブタジエンを含有するポリブタジエンをトレッドゴムに使用することにより、耐チップカット性能を損なうことなく耐摩耗性を向上させることができる。すなわち、本発明は、平均一次粒子径が100nm以下であるシンジオタクチック-1,2-ポリブタジエンが分散されたブタジエンゴムを、ゴム成分中に10~30重量%含有するトレッド用ゴム組成物である。
