新型炭黑D11在低滚动阻力轮胎胎面胶中的应用

Application of New Type Carbon Black D11 in Tread Compound of Low Rolling Resistance Tire

研究商品名为Propel D11的新型炭黑(简称炭黑D11)在低滚动阻力轮胎胎面胶中的应用。结果表明,炭黑D11等量替代炭黑N375,胶料的耐磨性能和撕裂强度大幅提高,抗湿滑性能提高,定伸应力和拉伸强度略有提高,但压缩疲劳温升升高,滚动阻力有所升高。在低滚动阻力轮胎胎面胶中添加炭黑D11可以有效提高其耐磨性能和撕裂强度。

The application of new type carbon black under the trade name Propel D11（referred to as carbon black D11） in the tread compound of low rolling resistance tire was studied. The results showed that,compared with carbon black N375 filled compound,the wear resistance and tear strength of the compound with the same amount of carbon black D11 were better,the wet skid resistance was improved,the tensile modulus and tensile strength increased,but the temperature rise in dynamic compression fatigue test increased,and the rolling resistance also increased slightly. It was concluded that the addition of carbon black D11 to the tread compound of low rolling resistance tire could effectively improve the wear resistance and tear strength.
