METHOD FOR PREPARING MULTI-FUNCTIONAL FILLER USEFUL FOR WALL FINISHING MATERIALS

摘要

PURPOSE: A manufacturing method of a polyfunctional filler provides a polyfunctional filler which prevents the growth of mold and bacteria under a moist condition and continuously reduces harmful gas when applied to a wall-finishing material. CONSTITUTION: A manufacturing method of a polyfunctional filler for wall-finishing material comprises a step of mixing zeolite with nanosilver colloid aqueous solution with a mixing ratio of 1:1; a step of stirring the mixture by 200 rpm at room temperature for 2 hours and drying the mixture at 110C for 4 hours; and a step of mixing the treated zeolite with TiO2 sol which is a photocatalyst with a mixing ratio of 1:1 by 200 rpm at room temperature for 2 hours; and a step of drying the mixture at 110C for 4 hours and heating the mixture for 2 hours at 300-600C.
