The invention discloses a method for preparing micro-capsulized superfine red 
phosphorus, boiling the superfine red 
phosphorus with 
vitriol, 
sodium cyanide solution and 
sodium hydroxide solution, separately, filtering, eliminating impurities, and 
drying, and storing by sealing; blending and dissolve 
metal compound, depositing with 
ammonia, centrifuging and adding water to dilute, raising temperature, dropping in 
aluminum nitrate, 
vitriol or HCl and making 
metal hydroxide sol; mixing propylene acylamide monomers and N, Ní»-
methylene dipropylene acylamide with 
ammonium persulphate, raising temperature and reacting to form high 
molecular network gel; adding the high 
molecular network gel into the 
metal hydroxide sol, raising the temperature and reacting to form high 
molecular network gel of 
metal hydroxide, mixing the high molecular network gel of 
metal hydroxide with the processed superfine red 
phosphorus, blending and placing still so that the 
sol takes the red phosphorus as the center to make surface absorption to form gel and 
coating a layer of 
colloid membrane on the red phosphorus surface, so as to obtain the micro-capsulized superfine red phosphorus. The advantages of the invention: it improves the stability, invariability and surface activity of the red phosphorus, improving 
processing property.
