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 excellent steering stability, rolling resistance, and wear resistance; 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 represented by formula (1), 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)-(ii): (i) a weight average molecular weight (Mw) of 15,000-120,000; and (ii) a vinyl content of 70 mol% or less.
(FR) L'invention fournit une composition de caoutchouc pour pneumatique antidérapant qui se révèle excellente en termes de stabilité de conduite, de performances de résistance au roulement et de résistance à l'usure, 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 représenté par la formule (1), et 20 à 150 parties en masse d'une charge (C). Ledit caoutchouc diène liquide modifié (B) satisfait les points (i) et (ii) suivants : (i) une masse moléculaire moyenne en poids (Mw) comprise entre 15000 et 120000, et (ii) une teneur en vinyle inférieure ou égale à 70% en moles.
(JA) 操縦安定性、転がり抵抗性能及び耐摩耗性に優れる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、下記式(1)で表され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)~(ii)、(i) 重量平均分子量(Mw)が15,000~120,000、(ii) ビニル含有量が70モル%以下、を満たす、高グリップタイヤ用ゴム組成物。
