Title (EN) RUBBER COMPOSITION
(FR) COMPOSITION DE CAOUTCHOUC
(JA) ゴム組成物
Abstract:
(EN) Provided is a rubber composition which has excellent ozone resistance and high adhesiveness to metallic members and which can give rubber products that are inhibited from deteriorating in appearance. The rubber composition is characterized by comprising a rubber component comprising a diene-based rubber, a wax, and calcium oxide, the content of the wax being 1 part by mass or more per 100 parts by mass of the rubber component, and the content of the calcium oxide being 0.5-10 parts by mass per 100 parts by mass of the rubber component.
(FR) L'invention concerne une composition de caoutchouc qui présente une excellente résistance à l'ozone et une adhésivité élevée à des éléments métalliques et qui permet d'obtenir des produits en caoutchouc qui ne se détériorent pas en apparence. La composition de caoutchouc est caractérisée en ce qu'elle comprend un constituant de caoutchouc comprenant un caoutchouc à base de diène, une cire et de l'oxyde de calcium, la teneur en cire étant de 1 partie en masse ou plus pour 100 parties en masse du constituant de caoutchouc, et la teneur en oxyde de calcium étant de 0,5 à 10 parties en masse pour 100 parties en masse du constituant de caoutchouc.
(JA) 耐オゾン性に優れる上、ゴム製品に用いられた場合に当該ゴム製品の外観性の悪化を抑制することができ、且つ、金属部材との接着性が高い、ゴム組成物を提供する。ゴム組成物は、ジエン系ゴムを含むゴム成分と、ワックスと、酸化カルシウムとを含有し、前記ワックスの含有量が、前記ゴム成分100質量部に対して1質量部以上であり、前記酸化カルシウムの含有量が、ゴム成分100質量部に対して0.5質量部以上10質量部以下であることを特徴とする。
