摘要:
以合成二氧化硅为原料,采用硅烷偶联剂对其进行表面改性处理。结果表明:硅烷偶联剂与二氧化硅表面羟基发生反应,当使用量达到16%,改性处理时间达到4小时,使二氧化硅具有良好的疏水性能。

Abstract: Synthetic silicon dioxide as raw material is modified with silane coupling agent. The results show that silane coupling agent had reacted with hydroxyl group and made the surface of the silicon dioxide have good hydrophobicity, while the modified condition should be over 16 percent and 4 hours of reacting.
