摘要
采用充油SBR1721和低滞后炭黑DZ-13开发高性能子午线轮胎胎面胶配方,并试制185/60R14 82H轿车子午线轮胎。结果表明,试验配方胶料的基本物理性能与生产配方相差不大;损耗因子(tanδ)在40~100℃内较小,胶料的滚动阻力和生热降低,tanδ在-15^+15℃内较大,胶料的抗冰滑和抗湿滑性能优异;试验轮胎在冰滑和湿滑路面上的抓着力较大,行驶时牵引力增大,制动距离明显缩短,同时滞后损失和生热降低,即轮胎的抗滑性能、滚动阻力和耐磨性能获得很好的平衡。
A tread compound for performance tire was developed with oil-extended SBR1721 and low hysteresis carbon black DZ-13,and 185/60R14 82H PCR tire was made with the above compound in pilot production. The results showed that the basic physical properties of test compound were similar to those of existent production compound; the rolling resistance and heat build-up of test compound decreased because of smaller tan8 at 40-100℃ ,and the ice and wet traction improved significantly because of greater tan8 at -15 - ＋15 ℃;and a performance tire with good balanced traction, rolling resistance and wear resistance was obtained with the test tread compound.
