PURPOSE: An encapsulation method of inorganic particles with organic polymer material is provided, in which anionic emulsifier is used in case that the surface of inorganic particles are charged to positive, and vice versa. CONSTITUTION: The encapsulation method comprises: dissolving completely 0.05-5 wt.% of anionic emulsifier or 2-10 wt.% of cationic emulsifier into the water with controlled hydrogen concentration, keeping the concentration of the emulsifier under critical micelle concentration; absorbing the emulsifier on the surface of 50-1,000 wt.% of the inorganic particles in a reactor by stirring for 0.5-3 hours; and adding 100 wt.% of the vinyl monomers such as styrene or acrylate, raising the temperature up to 70°C and adding 0.3-1.5 wt.% of reaction initiator to emulsion polymerize for encapsulation and to obtain 95% of yield.
