Method of hydrophobing silica |
摘要 |
A method of producing hydrophobic colloidal silica is disclosed. The method comprises combining an aqueous colloidal silica dispersion, polyorganosiloxane, and anionic surfactant to yield a stable aqueous emulsion of hydrophobic colloidal silica. The emulsion may be further processed by evaporating the water to yield a white material which may be easily ground to a fine powder of hydrophobic colloidal silica. This powder is useful as a reinforcement for silicone rubber.
