Title
(EN) TREAD RUBBER COMPOSITION FOR STUDLESS TIRES
(FR) COMPOSITION DE CAOUTCHOUC DE BANDE DE ROULEMENT POUR PNEUS SANS CLOUS
(JA) スタッドレスタイヤ用トレッドゴム組成物
Abstract
(EN) The present invention provides: a rubber composition which is for studless tires and which can improve on-ice performance and wear resistance in a well-balanced manner irrespective of the temperature; and a studless tire using the rubber composition. The present invention pertains to a rubber composition which is for a studless tire and which contains: a rubber component containing an isoprene rubber and a butadiene rubber; water-soluble fine particles; and a liquid plasticizer, wherein the liquid plasticizer has a glass transition temperature of -50°C or lower, and the contained amount of the liquid plasticizer is more than 30 parts by mass with respect to 100 parts by mass of the rubber component.
(FR) La présente invention concerne : une composition de caoutchouc qui est destinée à des pneus sans clous et qui peut améliorer les performances sur glace et la résistance à l'usure d'une manière bien équilibrée quelle que soit la température ; et un pneu sans clous utilisant la composition de caoutchouc. La présente invention concerne une composition de caoutchouc qui est destinée à un pneu sans clous et qui contient : un composant de caoutchouc contenant un caoutchouc d'isoprène et un caoutchouc de butadiène ; des particules fines solubles dans l'eau ; et un plastifiant liquide, le plastifiant liquide ayant une température de transition vitreuse de -50 °C ou moins, et la quantité contenue du plastifiant liquide étant supérieure à 30 parties en masse par rapport à 100 parties en masse du composant de caoutchouc.
(JA) 本発明は、温度に関わらず、氷上性能及び耐摩耗性をバランス良く改善できるスタッドレスタイヤ用ゴム組成物、及びこれを用いたスタッドレスタイヤを提供する。 本発明は、イソプレン系ゴムとブタジエンゴムとを含有するゴム成分、水溶性微粒子、及び液体可塑剤を含み、液体可塑剤はガラス転移温度が-50℃以下であり、ゴム成分100質量部に対する液体可塑剤の含有量が30質量部を超えているスタッドレスタイヤ用トレッドゴム組成物に関する。
