Title:
PREPARATION METHOD FOR HYDROPHOBIC INORGANIC POWDER MATERIAL
Document Type and Number:
WIPO Patent Application WO/2017/215544
Kind Code:
A1
Abstract:
Disclosed is a preparation method for a hydrophobic inorganic powder material. The preparation method comprises the following steps: mixing and grinding an inorganic powder material and a hydrophobic material; and after grinding, uniformly coating the surface of the inorganic powder material with the hydrophobic material, and separating and removing the redundant hydrophobic material to obtain the hydrophobic inorganic powder material. The preparation method is simple, low in cost, and green and environmentally protective. Also disclosed is the hydrophobic inorganic powder material prepared and obtained by using this method, wherein the particle size of the material is 0.01-500 μm, the hydrophobic performance is excellent, and the contact angle with water can reach 150º.
