间苯二甲酰肼在低滚动阻力轮胎中的应用

Application of M-phthaloyl Hydrazide in Low Rolling Resistance Tire

研究间苯二甲酰肼DC-02(简称DC-02)在低滚动阻力轮胎中的应用。结果表明:在基部胶和胎侧胶中加入DC-02,胶料的门尼粘度增大,门尼焦烧时间缩短,硫化特性和物理性能变化不大,动态生热明显降低,DC-02的用量以0.1~0.5份为宜;成品轮胎的滚动阻力降低,高速和耐久性能满足国家标准要求。

The application of m-phthaloyl hydrazide DC-02 in low rolling resistance tire was studied.The results showed that by adding DC-02 in the base compound and sidewall compound,the Mooney viscosity of the compounds increased,the scorch time was shortened,the vulcanization characteristics and physical properties changed little and the dynamic heat build-up decreased significantly. The appropriate dosage of DC-02 was 0. 1~0. 5 phr. The rolling resistance of the finished tire decreased and the high speed performance and durability met the requirements of national standards.
