不同类型抗湿滑树脂在白炭黑胎面胶中的协同应用研究

Study on Synergistic Application of Different Kinds of Anti-skid Resins in Silica Filled Tread Compound

研究不同类型抗湿滑树脂在白炭黑胎面胶中的协同应用效果。结果表明:与空白配方胶料相比,加入不同组合抗湿滑树脂胶料的门尼粘度和交联密度降低,邵尔A型硬度、300%定伸应力和回弹值减小,拉伸强度和拉断伸长率增大,耐磨性能下降,白炭黑分散性和抗湿滑性能提高,滚动阻力增大;两种不同类型抗湿滑树脂的协同使用可以很好地平衡胎面胶的动态力学性能。

The synergistic application effect of different kinds of anti-skid resins in the silica filled tread compound was studied.The results showed that compared with the blank formula compound,the Mooney viscosity and crosslink density of the compound with different combinations of anti-skid resins decreased,the shore A hardness,modulus at 300%elongation and rebound value decreased,the tensile strength and elongation at break increased,the wear resistance decreased,the dispersion of silica and wet skid resistance were improved,and the rolling resistance increased.The dynamic mechanical properties of the tread compound could be well balanced by the synergistic use of two different kinds of anti-skid resins.
