Beschreibung
Zusammenfassung:	The invention discloses fumed silica flatting powder and its preparation method. Base stock of the flatting powder is uniform fumed silica with its particle size being 3-8 micrometers. The base stock undergoes surface amination treatment. The preparation method comprises the following steps: hydrolyzing chlorosilane in high-temperature oxyhydrogen flame to prepare the nanometer fumed silica; during aggregation process, surface amination treatment is finished; a product with by-products removed is ground to specific particle size, and then grading treatment is carried out to prepare the fumed silica flatting powder. The product can be widely used in multiple complex systems to achieve an excellent flatting effect.
