【摘要】 介绍了４０目活化改性胶粉在轻载子午线轮胎胎面胶中的应用及其对胶料的硫化特性、物理性能的影响。结果表明，在轻载子午线轮胎胎面中加入１０份活化改性胶粉对轮胎使用寿命无不良影响，且可降低轮胎生产成本；添加了活化改性胶粉的胶料，老化后能保持较高的相对耐磨性，半成品尺寸稳定性好。更多还原

【Abstract】 A study was made into the application of 40 mesh activated crumb to the radial light truck tire tread and its influence on the physical properties and curing characteristics of compound The results showed that the addition of 10 phr of activated crumb to the radial light truck tire tread resulted in a decrease of tire cost without adverse effect on the tread life; a relative high wear resistance of tread compound with activated crumb after aging could be maintained, and the good dimensional stability of semi product was obtained更多还原
