Title (EN) RUBBER COMPOSITION AND PNEUMATIC TIRE
(FR) COMPOSITION DE CAOUTCHOUC ET PNEU
(JA) ゴム組成物、及び空気入りタイヤ
Abstract:
(EN) The present invention provides: a rubber composition which contains a white filler, but has a low rubber viscosity during kneading and therefore has excellent workability, and provides excellent fuel efficiency and wear resistance, and good vulcanization productivity; and a pneumatic tire using the rubber composition. The present invention pertains to a rubber composition containing a rubber component, a white filler, and a compound represented by formula (1), wherein the contained amount of the white filler is 5-200 parts by mass with respect to 100 parts by mass of the rubber component. In formula (1), X represents -CONH-, R1 represents an alkyl group having 7-23 carbon atoms or an alkenyl group having 7-23 carbon atoms, R2 represents an alkylene group having 1-3 carbon atoms, R3 and R4 each independently represent a hydrogen atom, an alkyl group having 1-3 carbon atoms, or a hydroxyalkyl group having 1-3 carbon atoms, and at least one of R3 and R4 is said hydroxyalkyl group.
(FR) La présente invention concerne : une composition de caoutchouc qui contient une charge blanche mais présente une faible viscosité de caoutchouc pendant le malaxage, et donc une excellente aptitude au façonnage, et confère un excellent rendement énergétique et une excellente résistance à l'usure, et une bonne productivité de vulcanisation ; et un pneu utilisant cette composition de caoutchouc. La présente invention concerne une composition de caoutchouc contenant un composant de caoutchouc, une charge blanche et un composé représenté par la formule (1), la teneur en charge blanche étant de 5 à 200 parties en masse pour 100 parties en masse du composant de caoutchouc. Dans la formule (1), X représente -CONH-, R1 représente un groupe alkyle doté de 7 à 23 atomes de carbone ou un groupe alcényle doté de 7 à 23 atomes de carbone, R2 représente un groupe alkylène doté de 1 à 3 atomes de carbone et R3 et R4 représentent chacun indépendamment un atome d'hydrogène, un groupe alkyle doté de 1 à 3 atomes de carbone ou un groupe hydroxyalkyle doté de 1 à 3 atomes de carbone, et R3 et/ou R4 représente(nt) ledit groupe hydroxyalkyle.
(JA) 本発明は、白色充填剤を含有するにもかかわらず、混練り中のゴム粘度が低く加工性に優れ、低燃費性及び耐摩耗性に優れ、さらに、加硫生産性が良好なゴム組成物、及びこ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、白色充填剤、及び下記式(1)で表される化合物を含有し、前記ゴム成分100質量部に対する前記白色充填剤の含有量が5~200質量部であるゴム組成物に関する。式(1)中、Xは-CONH-を表す。Rは炭素数7~23のアルキル基又は炭素数7~23のアルケニル基を表す。Rは炭素数1~3のアルキレン基を表す。RとRはそれぞれ独立して、水素原子、炭素数1~3のアルキル基又は炭素数1~3のヒドロキシアルキル基を表し、少なくとも1つは前記ヒドロキシアルキル基である。
