Title (EN) RUBBER COMPOSITION FOR HIGH GRIP TIRE
(FR) COMPOSITION DE CAOUTCHOUC POUR PNEUMATIQUE ANTIDÉRAPANT
(JA) 高グリップタイヤ用ゴム組成物
Abstract:
(EN) Provided are: a rubber composition for a high grip tire having highly balanced wet grip performance, dry grip performance, and steering stability; a tire tread partially using said rubber composition; a bead filler; a tire belt; and a pneumatic tire. The rubber composition for a high grip tire contains 0.1-90 parts by mass of a modified liquid diene-based rubber (B) having a functional group derived from a silane compound having a specific structure, and 20-150 parts by mass of a filler (C) with respect to 100 parts by mass of a solid rubber (A) containing 60 mass% or more of a styrene butadiene rubber having a styrene content of at least 20 mass%, wherein the modified liquid diene-based rubber (B) satisfies (i)-(iii): (i) a weight average molecular weight (Mw) of no less than 1,000 and less than 15,000; (ii) a vinyl content of 70 mol% or less; and (iii) 1-20 functional groups on average per one molecule of the modified liquid diene-based rubber (B).
(FR) L'invention fournit une composition de caoutchouc pour pneumatique antidérapant qui combine selon un équilibre élevé performances d'adhérence sur route mouillée, performances d'adhérence sur route sèche et stabilité de conduite, et une bande de roulement de pneumatique, un bourrage sur tringle, une ceinture de pneumatique ainsi qu'un pneumatique qui mettent en partie en œuvre cette composition. La composition de caoutchouc pour pneumatique antidérapant de l'invention comprend pour 100 parties en masse d'un caoutchouc solide (A) comprenant 60% en masse d'un caoutchouc butadiène-styrène de teneur en styrène supérieure ou égale à 20% en masse, 0,1 à 90 parties en masse d'un caoutchouc diène liquide modifié (B) possédant un groupe fonctionnel dérivé d'un composé silane de structure spécifique, et 20 à 150 parties en masse d'une charge (C). Ledit caoutchouc diène liquide modifié (B) satisfait les points (i) à (iii) suivants : (i) une masse moléculaire moyenne en poids (Mw) supérieure ou égale à 1000 et inférieure à 15000, (ii) une teneur en vinyle inférieure ou égale à 70% en moles, et (iii) un nombre moyen de groupes fonctionnels par molécule de caoutchouc diène liquide modifié (B) compris entre 1 et 20.
(JA) ウェットグリップ性能、ドライグリップ性能、及び操縦安定性を高いバランスで兼ね備えた高グリップタイヤ用ゴム組成物、これを一部に用いたタイヤトレッド、ビードフィラー、タイヤ用ベルト及び空気入りタイヤを提供する。 スチレン含有量が20質量%以上であるスチレンブタジエンゴムを60質量%以上含有する固形ゴム(A)100質量部に対して、特定の構造を有するシラン化合物に由来する官能基を有する変性液状ジエン系ゴム(B)を0.1~90質量部、及びフィラー(C)を20~150質量部含有する高グリップタイヤ用ゴム組成物であり、前記変性液状ジエン系ゴム(B)が、下記(i)~(iii)、(i)重量平均分子量(Mw)が1,000以上15,000未満、(ii)ビニル含有量が70モル%以下、(iii)変性液状ジエン系ゴム(B)一分子当たりの平均官能基数が1~20個、を満たす、高グリップタイヤ用ゴム組成物。
