Beschreibung
Zusammenfassung:	The invention relates to a nanometer inorganic-organic coated mica powder. The nanometer inorganic-organic coated mica powder contains mica used a core, a nano-metal compound used a middle layer a nano-thickness organic surface modifier as a shell, the mass of nano-oxide is 0.01-2% of the mass of the mica, and the mass of the organic surface modifier is 0.01-2% of the mass of the mica. A preparation method of the powder comprises the following steps: adding the mica into a coating reaction device, carrying out a coating reaction on the mica, used as a basic carrier, and a nanometer inorganic material having a particle size of 20-200 nm, carrying out coating modification on the coated mica and the organic surface modifier, and controlling the thickness of the obtained coating film at 20-200nm in order to obtain the powder. The mica is coated and modified to improve the heat resistance, chemical resistance, dispersibility and other properties, so the coated mica powder can be applied tothe rubber plastic indust
