Active stephanoporate mineral TiO2-doped composite catalytic antimicrobial material preparation and using method

Abstract

The invention discloses a preparation and using method of multiple active porous mineral doped nano-TiO2 composite catalytic anti-bacterial materials, and the preparation and using method belongs to the technical field of new material. The main technical key point of the invention is to combine the anti-bacterial mechanism of the ion modified porous minerals and the photo-catalytic anti-bacterial mechanism of the element doped nano-TiO2 to realize the synergistic anti-bacterial role, the modification of the porous minerals by the metal anti-bacterial ion (one of Ag<+>, Cu<2+>, Zn<2+> and Fe<3+>) and the rare earth ion and the nano-TiO2 doped synchronous composite process technology by the metal anti-bacterial ion and the rare earth ion are realized during the preparation process, thereby obtaining the composite catalytic anti-bacterial composite materials which are characterized by broad-spectrum, long-acting effect and safety, etc. The composite catalytic anti-bacterial products prepared by adopting the method and the technical process have low cost, anti-bacterial and long-acting effects, broad-spectrum and good synergistic anti-bacterial effect, the preparation process of the materials has the advantages of simpleness and strong operationality, and the like, so the preparation and using method can be widely applied in anti-bacterial coating, putty, fabric and other industries.
