MANUFACTURING METHOD OF INORGANIC POWDER TREATED WITH FUNCTIONAL ORGANOSILANE ON ITS SURFACE, AND THE POWDER

摘要

Provided are a method for preparing an inorganic powder whose surface is treated with an organic silane to improve the surface treatment efficiency by a simple process, and an inorganic powder whose surface is treated with an organic silane prepared by the method. A method comprises the steps of adding 0.1-50 parts by weight of an organic silane to 100 parts by weight of an inorganic solution to form an organic group on the surface of an inorganic particle; applying an ultrasonic wave to the product to discharge the organic group-surface treated inorganic particle and a solvent to air; dehydrating and condensing the discharged solvent and inorganic particle to form an inorganic powder whose surface is treated with an organic group; and collecting the inorganic powder.
