中文摘要: |
对两个厂家生产的高分散性白炭黑A和B进行特性表征和应用性能测试。结果表明:高分散性白炭黑A和B均能够满足国家标准要求;与高分散性白炭黑A相比,高分散性白炭黑B表面羟基含量高、孔径较小、比表面积大,在胶料中较难分散,粒子易团聚,胶料的Payne效应大,滚动阻力高,与橡胶大分子结合程度高,对胶料的补强效果好。 |
英文摘要: |
The basic properties of highly dispersible silica A and B were characterized and their effect on the properties of rubber compound were studied.The results showed that highly dispersible silica A and B could meet the requirements of national standards.Compared with highly dispersible silica A,highly dispersible silica B had higher hydroxyl content on the surface,smaller pore size and larger specific surface area,and was difficult to disperse in the compound,the particles were easy to agglomerate,the Payne effect of the compound was large,the rolling resistance was high.The highly dispersible silica B had high bonding degree with rubber macromolecules,and the reinforcing effect on the compound was good. |
