  公开（公告）日：2011-05-25

  The present invention aims to provide a rubber composition that improves heat resistance and particularly inhibits the changes in properties such as hardness of the vulcanized rubber composition (rubber hardening degradation) due to long-term use without an increased amount of an age resistor, thereby extending the life-span without deterioration of performance on ice, and reduces vulcanization time while maintaining good scorch resistance, and increases cross-linking efficiency; and a studless tire having a cap tread produced from the composition. The rubber composition for a cap tread of the invention comprises: a rubber component containing an isoprene-based rubber; silica; a compound represented by formula (I) and/or (II); and a thiuram vulcanization accelerator, wherein R1 and R2 may be the same or different, and each represent a hydrogen atom, an alkyl group, an aryl group, or an aralkyl group, provided that the case where R1 and R2 are simultaneously hydrogen atoms is excluded.

  本发明旨在提供一种橡胶组合物，该组合物可提高耐热性，尤其可抑制硫化橡胶组合物因长期使用而导致的硬度等性能变化（橡胶硬化降解），且无需增加抗老化剂的用量，从而可延长使用寿命而不会降低冰上性能，并可缩短硫化时间，同时保持良好的耐焦烧性，还可提高交联效率；以及一种无钉轮胎，该轮胎具有由该组合物生产的盖胎面。本发明的盖胎面橡胶组合物包括：含有异戊二烯基橡胶的橡胶组分；白炭黑；由式（I）和/或（II）代表的化合物；以及秋兰姆硫化促进剂、 其中 R1 和 R2 可以相同或不同，各自代表氢原子、烷基、芳基或芳烷基，但不包括 R1 和 R2 同时为氢原子的情况。
