钕系顺丁橡胶在绿色轮胎胎面胶中的应用

Application of Nd BR in Tread Compound of Green Tire

研究钕系顺丁橡胶(Nd BR)在绿色轮胎胎面胶中的应用。结果表明:与未采用Nd BR的胎面胶相比,采用20份Nd BR的胎面胶门尼粘度较大,门尼焦烧时间较短;强伸性能相当或略差,耐热老化性能和耐磨性能提高,滚动阻力和生热降低。Nd BR有利于提高胎面胶耐磨性能及降低滚动阻力和生热,可作为绿色轮胎用原材料。

The application of Nd-catalyzed butadiene rubber（Nd BR） in the tread compound of green tire was investigated. The results showed that,compared with the tread compound without Nd BR,the Mooney viscosity of the tread compound with 20 phr Nd BR was higher and Mooney scorch time was shorter,the tensile properties were similar or slightly worse,the thermal aging resistance and abrasion resistance were better,and the rolling resistance and heat generation were lower. Nd BR was helpful to improve the abrasion resistance of the tread compound and reduce rolling resistance and heat generation,which could be used as raw materials for green tires.
