Title (EN) TREAD RUBBER COMPOSITION, AND PNEUMATIC TIRE
(FR) COMPOSITION DE CAOUTCHOUC POUR BANDE DE ROULEMENT, ET PNEUMATIQUE
(JA) トレッド用ゴム組成物及び空気入りタイヤ
Abstract:
(EN) The present invention provides: a tire rubber composition capable of imparting significantly improved wet grip performance; and a pneumatic tire using the rubber composition. The present invention pertains to a tread rubber composition which contains: a rubber component including styrene butadiene rubber; fine silica particles having a particle size of 18 nm or less; and a silane coupling agent containing an alkoxysilyl group, a sulfur atom, and six or more carbon atoms linking the alkoxysilyl group and the sulfur atom, wherein A × B ≤ 3000 is satisfied, where A represents the total mass of silica as expressed in parts by mass, and B represents the total mass of styrene as expressed in parts by mass, with respect to 100 parts by mass of the rubber component.
(FR) La présente invention concerne : une composition de caoutchouc pour pneu capable de conférer une performance d'adhérence sur sol mouillé significativement améliorée ; et un pneu l'utilisant. La composition de caoutchouc pour bande de roulement selon l'invention contient : un composant caoutchouc comprenant un caoutchouc styrène-butadiène ; de fines particules de silice ayant une taille de particule de 18 nm ou moins ; et un agent de couplage au silane contenant un groupe alcoxysilyle, un atome de soufre et six atomes de carbone ou plus liant le groupe alcoxysilyle et l'atome de soufre, où A × B ≤ 3000 est satisfait, quand A représente le poids total de silice exprimé en parties en poids, et B représente le poids total de styrène exprimé en parties en poids, pour 100 parties en poids de composant caoutchouc.
(JA) 本発明は、ウェットグリップ性能を顕著に改善できるタイヤ用ゴム組成物、及びこれを用いた空気入りタイヤを提供する。 本発明は、スチレンブタジエンゴムを含むゴム成分と、粒径18nm以下の微粒子シリカと、アルコキシシリル基及び硫黄原子を含み、かつアルコキシシリル基及び硫黄原子を連結する炭素原子の数が6個以上であるシランカップリング剤とを含み、前記ゴム成分100質量部に対する総シリカ質量をA質量部、総スチレン質量をB質量部としたときに、A×B≦3000を満たすトレッド用ゴム組成物に関する。
