A rubber composition having a reduced heat build-up, which comprises (a) 100 wt. parts of an elastomer capable of being crosslinked by an organic peroxide crosslinking agent, (b) 10 - 150 wt. parts of a metal salt of an α,β-ethylenically unsaturated carboxylic acid, (c) 5 to 100 wt. parts of magnesium oxide having a BET specific surface area not larger than 25 m2/g, and (d) 0.1 to 30 wt. parts of an organic peroxide crosslinking agent. A roll having an outer peripheral surface portion composed of a vulcanizate of the rubber composition. The roll has high strengths and reduced heat build-up, and is especially suitable for use under a high load.
一种可减少热积累的橡胶组合物,其中包括:(a) 100 重量份可被有机过氧化物交联剂交联的弹性体;(b) 10 - 150 重量份的α,β-乙烯基不饱和羧酸的金属盐;(c) 5 - 100 重量份的氧化镁,其 BET 比表面积不大于 25 m2/g;(d) 0.1 - 30 重量份的有机过氧化物交联剂。辊子的外周表面部分由橡胶组合物硫化而成。该辊强度高,热量积聚少,特别适合在高负荷下使用。
