| 摘 要： | 气相白炭黑是一种二氧化硅纳米材料，气相白炭黑的最主要应用是用于硅橡胶的补强，但气相白炭黑在硅橡胶中很难分散，影响了补强效果，本文用六甲基二硅氮烷对白炭黑进行表面处理并对白炭黑表面处理率问题做一些探讨。

| Abstract: | The degree of the surface preparation of fumed silica can be judged by the C content when fumed silica is prepared by HMDZ. The effect of the ratio of fumed silica to HMDZ and the effects of reaction temperature and differcnt solvents on the properties of hydrophobic fumed silica were discussed. The method of judgement of the surface preparation can also be proved by the properties of the RTV silicone rubber. |
