Application of Silane Coupling Agent TESPT/OTES Blend System in Silica Filled Rubber Compound

研究硅烷偶联剂TESPT/OTES并用体系在白炭黑胶料中的应用。结果表明:随着硅烷偶联剂OTES用量的增大,胶料的门尼粘度减小,门尼焦烧时间延长,Payne效应降低,白炭黑分散性提高;硫化胶的抗湿滑性能提高,滚动阻力降低。

The application of silane coupling agent TESPT/OTES blend system in the silica filled rubber compound was studied.The results showed that,as the addition level of silane coupling agent OTES increased,the Mooney viscosity of the compound decreased,the Mooney scorch time was extended,the Payne effect decreased,the dispersion of silica was improved,the wet skid resistance of the vulcanizates was improved,and the rolling resistance decreased.
