The Characterization of Silicon Powder Modified by Silane Coupling Agent and its Effect

Silicon powder is a kind of important nonmetallic mineral. It not only reduce the cost of polymer materials, but also can improve the performance of materials. In order to make silicon powder play a better role, this paper shows that surface modification of silicon powder by using the silane coupling agents KH550 and KH560. Through hydrophobic property, infiltrating performance, activation index, infrared spectroscopy(FT-IR) and scanning electron microscopy (SEM).It can be find that the evaluation and characterization of silicon powder modification effect. Comprehensive analysis shows that the modification effect is best,when KH550 and KH560 is the ratio of 1:2.
