A rubber composition comprises a polyether-based polymer as a rubber component (a), a crosslinking agent (b), m-phenylenedimaleimide (c), and an antioxidant (d). It is preferable that the polyether-based polymer includes a constituent unit including at least two units selected from ethylene oxide, propylene oxide, epichlorohydrin, or allyl glycidyl ether. It is more preferable that the antioxidant (d) is at least one selected from a benzimidazole-based antioxidant, a nickel salt of a dialkyldithiocarbamic acid, an amine-based antioxidant, a phenol-based antioxidant, a thiourea-based antioxidant, an organic thio acid, or a phosphorous acid.
一种橡胶组合物包括作为橡胶成分的聚醚基聚合物 (a)、交联剂 (b)、间苯二马来酰亚胺 (c) 和抗氧化剂 (d)。聚醚基聚合物最好包括一个组成单元,其中至少有两个单元选自环氧乙烷、环氧丙烷、环氧氯丙烷或烯丙基缩水甘油醚。更优选的是,抗氧化剂 (d) 至少是选自苯并咪唑类抗氧化剂、二烷基二硫代氨基甲酸的镍盐、胺类抗氧化剂、苯酚类抗氧化剂、硫脲类抗氧化剂、有机硫代酸或磷酸中的一种。
