摘要

以粉煤灰为填料

采用Si-69、钛酸酯和硬脂酸三种偶联剂对其进行表面处理

采用红外光谱仪和扫描电镜分析了改性前后粉煤灰的表面结构和形貌

而后将粉煤灰添加到硅橡胶中

比较粉煤灰改性前后复合材料的力学性能和阻燃性能。实验结果表明:红外光谱证实三种偶联剂改变了粉煤灰的表面结构

SEM观察到改性后粉煤灰的比表面积得到了提高;改性粉煤灰/硅橡胶复合材料的力学性能和阻燃性能比未改性的粉煤灰/硅橡胶复合材料得到了较大的提高。当添加量为1%的硬脂酸改性粉煤灰/硅橡胶复合材料的力学性能和阻燃性能最佳。

Abstract

In this paper

fly ash modified by three different coupling included Si-69

titanate and stearic acid was used as filler to reinforce silicone rubber. The structure and morphology of modified and unmodified fly ash were characterized using by Fourier transform infrared spectroscopy and scanning electron microscope. The mechanical and flame retardancy properties of composites were compared. The result showed that the structure of modified fly ash was changed and the surface area was improved observed by FTIR and SEM. The mechanical properties and flame retardancy performance of modified fly ash/silicon rubber composites were greatly improved compared with unmodified fly ash. The best property of silicone rubber composite was added 1wt% fly ash modified by stearic acid.
