Abstract:
(EN) The main purpose of the present invention is to provide a rubber composition which has excellent workability and has an excellent balance of rolling resistance and wet grip performance. The present invention solves this problem by providing a rubber composition obtained by combining 1 part by mass to 30 parts by mass of a modified hydrocarbon resin and 80 parts by mass to 200 parts by mass of silica per 100 parts by mass of a diene rubber, the rubber composition being characterized in that the modified hydrocarbon resin is a hydrocarbon resin modified by at least one compound from among an amine compound, an amide compound, and an imide compound, the weight average molecular weight (Mw) of the modified hydrocarbon resin is in the range of 1000–8000, and the softening point of the modified hydrocarbon resin is in the range of 80°C–150°C.
(FR) L’invention a pour objet de fournir une composition de caoutchouc qui présente une excellente usinabilité, et un excellent équilibre entre résistance au roulement et performance d’adhérence sur sol mouillé. Plus précisément, l’invention concerne une composition de caoutchouc qui est constituée par mélange de 1 à 30 parties en masse d’une résine hydrocarbure modifiée, et de 80 à 200 parties en masse d’une silice pour 100 parties en masse d’un caoutchouc diénique. Cette composition de caoutchouc est caractéristique en ce que ladite résine hydrocarbure modifiée est telle qu’une résine hydrocarbure est modifiée par au moins un composé parmi un composé amine, un composé amide ou un composé imide. La masse moyenne moléculaire en poids (Mw) de la composition de caoutchouc est comprise dans une plage de 1000 à 8000, et son point de ramollissement est compris dans une plage de 80 à 150°C.
(JA) 本発明は、加工性に優れ、かつ、転がり抵抗及びウェットグリップ性能のバランスに優れたゴム組成物を提供することを主目的とする。 本発明は、ジエン系ゴム100質量部に対し、変性炭化水素樹脂1質量部~30質量部およびシリカ80質量部~200質量部を配合してなるゴム組成物であり、上記変性炭化水素樹脂は、炭化水素樹脂を、アミン化合物またはアミド化合物またはイミド化合物のうち少なくとも1つの化合物で変性したものであり、重量平均分子量(Mw)が1000~8000の範囲内であり、かつ軟化点が80℃~150℃の範囲内であることを特徴とするゴム組成物を提供することにより、上記課題を解決する。
