白炭黑-聚合物接合界面的微观结构对轮胎性能显示的影响

Influence of Silica-polymer Bond Microstructure on tire performance indicators

白炭黑在轮胎生产中已经广泛使用,它能够改善轮胎抗湿滑性和滚动阻力。通过实验,研究了不同比表面积白炭黑对不同配方胶料物理性能的影响。考查了动态黏弹现象,表征橡胶填料相互作用影响轮胎胶料性能的机理。实验表明,选择合适的偶联剂可以调整白炭黑—填充橡胶的动态性能。

Silica has been widely used in the tire production which can improve the wet skid resistance and rolling resistance. The effect of the specific surface area of silica on physical properties of different formulations was investigated experimentally. The dynamic viscoelastic phenomenon was investigated which characterized the mechanism of the influences of rubber filler interaction on tire compound performance. Experimental results showed that we could adjust the dynamic performance of silica filled rubber by choosing the appropriate coupling agent.
