Synthesizing method for micro-silica treated with epoxy-terminated silicone the micro-silica and the micro-silica composite

摘要

The present invention relates to a microsilica synthesis method in which various types of epoxy-modified silicones are chemically bonded to the surface of microsilica to modify the surface thereof with an epoxy-modified silicone which is water repellent on its own, a microsilica synthesis method in which microsilica prepared by the above-The present invention relates to a microsilica composition having improved water repellency. The microsilica synthesis method wherein the surface is modified with the epoxy-modified silicone is characterized in that an epoxy silane treatment step, a diol treatment step and an epoxy-modified silicone treatment step are carried out to sequentially coat an epoxy silane layer, a diol layer and an epoxy-So that microsilica having excellent water repellency can be produced.;
