摘要

本文建立了恒温恒湿电晕老化平台，探讨了高温硫化硅橡胶的疏水性与表面微观结构的关系。采用疏水性/回收率测试、傅里叶红外光谱(FTIR)、陷阱密度、陷阱能级测试和扫描电镜测试分析了表面结构和表面元素分布。进一步讨论了电晕老化和疏水性损失与恢复的机理。

Hydrophobicity and Surface Microstructure Changing Regulations of HTV Silicone Rubber Under Corona Accelerated Aging

This paper built a constant temperature and humidity corona aging platform to explore relation between hydrophobicity and the surface micro-structure of high-temperature vulcanized silicone rubber. The hydrophobicity /recovery test, Fourier Transform infrared spectroscopy (FTIR), Trap density, trap energy level test and SEM test were applied to analysis the surface structure and the surface element distribution. The mechanism of corona aging and hydrophobicity loss and recovery is further discussed.
