Method for manufacturing nanometer antibacterial ceramic glaze layers
The invention belongs to the field of inorganic nonmetal materials, particularly discloses a method for manufacturing nanometer antibacterial ceramic glaze layers, and relates to methods for manufacturing ceramic glaze layers. Antibacterial elements are added into ceramic glaze layer bases to carry out antibacterial disinfection on the ceramic glaze layers. Precursors for superfine powder of the nanometer antibacterial ceramic glaze layers comprise 45-60% of SiO<2>, 10-14%of Al<2>O<3>, 7-10% of CaO, 5-7% of ZnO, 2-5% of CuO, 3-6% of MgO, 1-3% of TiO<2> and 0.2-2% of Ag<2>O. The method includes filling graphite containers with the precursors for proportionally preparing the superfine powder of the nanometer antibacterial ceramic glaze layers; preserving heat for 120min-240min under argon atmosphere protection and the condition of temperatures of 1250-1400 DEG C to carry out synthesis; adding absolute ethyl alcohol into a ball-mill to carry out mechanical ball-milling for 24 hours so as to obtain the superfine precursor powder with crystal grain sizes of 30-80nm. The method has the advantages that metal grains of zinc, copper, magnesium and silver are fine and are uniformly distributed in glaze layers, the diameters of the metal grains are 30-80nm, and antibacterial elements can be quickly, durably and continuously released.
