低滞后炭黑DZ-13在载重斜交轮胎中的应用

摘要

研究低滞后炭黑DZ-13在载重斜交轮胎胎面胶和胎肩胶中的应用.结果表明,与采用炭黑N234或N375补强的硫化胶相比,采用低滞后炭黑DZ-13补强的硫化胶弹性模量和回弹值较大,滚动阻力较低,但撕裂强度和抗湿滑性能较差;低滞后炭黑DZ-13更适合用于胎肩胶.%The application of low hysteresis carbon black DZ-13 in tread compound and shoulder compound of bias truck tire was investigated.The results showed that,compared to the vulcanizate reinforced by carbon black N234 or N375,the vulcanizate reinforced by low hysteresis carbon black DZ-13 possessed higher elastic modulus and rebound value,lower rolling resistance,but it also showed poorer tear strength and wet skid resistance;the low hysteresis carbon black DZ-13 was more suitable for the shoulder compound.
