Abstract

Selon la présente invention, la dureté et le module d'un produit durci d'une composition de caoutchouc pour des courroies de transmission, ladite composition de caoutchouc étant principalement composée d'un élastomère d'éthylène-a-oléfine, sont améliorés sans détériorer la résistance au froid, la résistance à la chaleur, l'adhésivité, la résistance à la fatigue en flexion et la résistance à l'usure. Selon la présente invention, une courroie de transmission est formée à partir d'un produit durci d'une composition de caoutchouc qui contient un constituant de caoutchouc qui contient un élastomère d'éthylène-a-oléfine, un sel métallique d'acide carboxylique à insaturation a,ß, un oxyde de magnésium, un peroxyde organique et une charge inorganique, et qui est ajusté de telle sorte que le rapport de l'oxyde de magnésium soit de 2 à 20 parties en masse par rapport à 100 parties en masse du constituant de caoutchouc, tout en étant supérieur ou égal à 5 parties en masse par rapport à 100 parties en masse du sel métallique d'acide carboxylique à insaturation a,ß. Le rapport du sel métallique d'acide carboxylique à insaturation a,ß peut être d'environ 5 à 40 parties en masse par rapport à 100 parties en masse du constituant de caoutchouc. Cette courroie de transmission est applicable en tant que courroie de transmission qui est utilisée pour un entraînement de transmission à variation continue, tel qu'une courroie trapézoïdale crantée à bord brut.
