| description | An objective of the present invention is to provide a rubber composition that, when applied to a tire, is capable of striking a balance between wet performance, low rolling resistance, and steering stability at high levels, and is capable of maintaining wet performance for extended periods of time. In order to solve the problem described above, the present invention is characterized by containing: a rubber component containing a modified styrene-butadiene rubber that has been modified by a nitrogen-containing alkoxysilane; a filler containing at least 40 parts by mass and less than 70 parts by mass silica per 100 parts by mass of the rubber component; and 3-35 parts by mass, per 100 parts by mass of the rubber component, of a polyolefin softener having a weight-average molecular weight (Mw) of 5,000-50,000.
L'invention a pour objet de fournir une composition de caoutchouc qui, lorsqu'elle est appliquée à un pneumatique, permet de concilier à un niveau élevé des performances sur route humide, une faible résistance au roulement et une stabilité de conduite, et permet simultanément de conserver ses performances sur route humide pour une longue durée. À cet effet, l'objet de l'invention est caractéristique en ce qu'il contient : un composant caoutchouc qui comprend un caoutchouc styrène-butadiène modifié résultant d'une modification par un alkoxysilane comprenant un azote ; 40 parties en masse ou plus à moins de 70 parties en masse d'une charge comprenant une silice pour 100 parties en masse dudit composant caoutchouc ; et 3 à 35% en masse d'un plastifiant à base de polyoléfine de masse moléculaire moyenne en poids (Mw) comprise entre ５０００ et ５００００ pour 100 parties en masse dudit composant caoutchouc.
タイヤへ適用した際、ウェット性能、低転がり抵抗性及び操縦安定性を高いレベルで両立できるとともに、ウェット性能を長期間維持できる、ゴム組成物を提供することを目的とする。 上記課題を解決するべく、本発明は、窒素含有アルコキシシランで変性された変性スチレンブタジエンゴムを含有するゴム成分と、前記ゴム成分１００質量部に対して４０質量部以上７０質量部未満のシリカを含有する充填剤と、前記ゴム成分１００質量部に対して３～３５質量部の、重量平均分子量（Ｍｗ）が５０００～５００００であるポリオレフィン系軟化剤と、を含むことを特徴とする。 |
