摘要：对炭黑填充轮胎胎面胶的动态力学性能进行研究。结果表明，炭黑品种对胎面胶玻璃化温度（Tg）的影响不大，但不同品种炭黑填充的胎面胶的损耗因子（tanδ）峰值却明显不同；炭黑 N351填充胎面胶的滞后损失较小，冰、湿路面的抓着性能也较好；随着炭黑 N351用量的增大，胎面胶的tanδ峰值逐渐降低，Tg向低温方向移动；在20～80 ℃范围内，炭黑 N351用量对胎面胶的储能模量和滞后性能影响较大；当炭黑 N351用量为75份时，胎面胶综合性能较好。

Abstract:The dynamic properties of CBfilled tread compound were investigated.The results showed that the kinds of carbon black gave little effect on the Tg of tread compound,but remarkable effect on the peak tanδ;the N351 blackfilled tread resulted in lower hysteresis and better ice and wet traction;the peak tanδ of tread compound decreased gradually and the Tg shifted to the low temperature region as the addition level of N351 black increased;the addition level of black N351 gave significant effect on the storage modulus and hysteresis of tread compound;and a tread compound with good comprehensive properties was obtained when 75 phr N351 black was used.
