4in solution, be added dropwise to complete rear placement a few hours to make seed-solution, standby;
3) by SnCl
4and SbCl
3join in certain density HCl, be configured to mixed solution, be slowly added drop-wise in the seed-solution in stirring with ammoniacal liquor, in this process, keep PH constant simultaneously;
4) filter, with deionized water, gained solid is cleaned, gained material is placed in vacuum drying chamber and is placed in Muffle furnace after dry again and calcines.
Step 1 wherein) SnCl configuring
4solution concentration is 0.01-0.1mol/L.
Step 3 wherein) concentration of hydrochloric acid using is 1-4mol/L.
Step 4 wherein) calcining heat of Muffle furnace is 500-1000 ℃, calcination time 4-10 hour.
The products characteristics of narrating in the present invention is for possessing nucleocapsid structure, and surface deposition has the light attapulgite powder of ATO conductive layer.
This technology is for the preparation with the nano-powder of conducting function, and the attapulgite powder obtaining can be applied to the preparation that light color has antistatic/conducting function fiber, meets people for the demand of safety to fabrics.
