Mildew-proof antibacterial material for ardealite building material and preparation method of mildew-proof antibacterial material

The invention discloses a mildew-proof antibacterial material for ardealite building materials and a preparation method of the mildew-proof antibacterial material, and belongs to the field of mildew-proof ardealite materials. The preparation method comprises the following steps: sintering ZnO powder and TiO2 powder in a lifting furnace at the temperature of 300 DEG C to obtain an antibacterial agent; the preparation method comprises the following steps: mixing phosphogypsum powder with ZnO-TiO2 powder subjected to solid-phase sintering, stirring with deionized water, and carrying out casting molding to obtain an antibacterial phosphogypsum block; the antibacterial agent is mixed in ardealite powder and deionized water before the ardealite powder and the deionized water are mixed and molded by casting, and the surface of an ardealite block molded by casting is coated with the antibacterial agent and the deionized water after being stirred. The ZnO-TiO2 composite powder obtained after solid-phase sintering has
