Vinyl acetate and sericite and water are mixed, and the sericite comprises: a raw ore analysis step of having mineral componential analysis of the sericite and the raw ore; a crushing and grinding step of crushing or grinding the raw ore; a physical refining step of refining the raw ore by a physical method; a zeta-potential measurement step of putting a reference sample of each impure minerals and measuring a zeta-potential; a collector selection step of selecting a first collector; a first reverse flotation step of removing a first floating impure mineral; a collector selection step of selecting a second collector floating in a second reference sample; and a second reverse flotation step of removing a second impure mineral. The present invention is capable of blocking a harmful electromagnetic wave and having an excellent self-washing effect to be used for an environmentally friendly finishing material. |
