Antimicrobial inorganic composite powder having excellent color stability and antimicrobial property and preparation thereof

摘要

The present invention is color stable and as antimicrobial activity is a method of manufacturing a superior new antibacterial inorganic compound powder and the material, antimicrobial inorganic composite powder of the present invention, particle size in the nanometer (㎚) the ultra-fine particles in the form of zinc oxide hydrate control in units the coated silica of 0.5~10 ㎛ (spherical, flaky, amorphous) particulate carrier which is adsorbed on the metal in which the sodium silicate component again after the doping reaction, and then by the new antibacterial inorganic composite powder prepared by heat treatment, conventional silver-based inorganic there is no disadvantage of metal-specific metallic color of the antibacterial powder eliminates the color transition to the use gray lines, the the ultra-fine state of zinc oxide and the metal produced in the heat treatment process, the composite can provide excellent antibacterial activity and a synergistic antibacterial activity and, also suitable controlled-release of the antimicrobial substance to the formation of the protective coating layer by the sodium silicate component It can provide a persistent antimicrobial activity.
