Title (EN) RUBBER COMPOSITION FOR INNER LINER AND PNEUMATIC TIRE
(FR) COMPOSITION DE CAOUTCHOUC POUR CALANDRAGE INTÉRIEUR, ET PNEUMATIQUE
(JA) インナーライナー用ゴム組成物及び空気入りタイヤ
Abstract:
(EN) The present invention provides: a rubber composition for an inner liner, said rubber composition having exceptional balance in terms of performance with regard to sheet processability and air barrier properties; and a pneumatic tire in which the rubber composition is used. The present invention pertains to a rubber composition for an inner liner, said rubber composition comprising a rubber component, a mixture of a fatty acid metal salt and a fatty acid amide, oil, and a C5 petroleum resin. The butyl-based rubber content in 100 mass% of the rubber component is 70 mass% or more, the contained amount of the mixture relative to 100 parts by mass of the rubber component is 0.8 to 3.2 parts by mass, and the total contained amount of the mixture, the oil, and the C5 petroleum resin is 6.0 to 16.0 parts by mass.
(FR) L’invention fournit une composition de caoutchouc pour calandrage intérieur qui présente un excellent équilibre de ses performances en termes d’usinabilité en feuille et de blocage d’air, et un pneumatique mettant en œuvre cette composition. Plus précisément, l’invention concerne une composition de caoutchouc pour calandrage intérieur qui contient un composant caoutchouc, un mélange de sel de métal d’acide gras et d’amide d’acide gras, une huile, et une résine de pétrole en C5, la teneur en caoutchouc à base de butyle est supérieure ou égale à 70% en masse pour 100% en masse dudit composant caoutchouc. Pour 100 parties en masse dudit composant caoutchouc, la teneur en mélange est comprise entre 0,8 et 3,2 parties en masse, et la teneur totale en mélange, en huile et en résine de pétrole en C5, est comprise entre 6,0 et 16,0 parties en masse.
(JA) 本発明は、シート加工性、空気遮断性の性能バランスに優れたインナーライナー用ゴム組成物、及びそれを用いた空気入りタイヤを提供する。本発明は、ゴム成分と、脂肪酸金属塩及び脂肪酸アミドの混合物と、オイルと、C5系石油樹脂とを含み、前記ゴム成分100質量%中のブチル系ゴムの含有量が70質量%以上、前記ゴム成分100質量部に対する前記混合物の含有量が0.8~3.2質量部、前記混合物、前記オイル及び前記C5系石油樹脂の合計含有量が6.0~16.0質量部であるインナーライナー用ゴム組成物に関する。
