NOVELTY - Preparing antistatic and antibacterial nano-composite functional powder involves selecting nano ceramic powder with a particle size of 30-60 nm, and performing surface activation treatment on the nano-ceramic powder to obtain activated nano-ceramic powder. The surface modification of activated nano ceramic powder is carried out, and dispersed the activated nano ceramic powder in absolute ethanol. A ceramic powder dispersion is obtained after full infiltration. The absolute ethanol and dispersant are taken to mix, after mixing, used high-speed shear to stir to obtain emulsion. The ceramic powder dispersion and the emulsion are mixed, stirred, and dried to obtain a modified activated nano ceramic powder. The formaldehyde is used as a reducing agent to silver-plated the modified activated nano-ceramic powder under room temperature and ultrasonic conditions to obtain nano-level silver-plated ceramic powder. USE - Method for preparing antistatic and antibacterial nano-composite functional powder. ADVANTAGE - The method has static electricity, antibacterial, anti-infrared and anti-ultraviolet functions. DETAILED DESCRIPTION - Preparing antistatic and antibacterial nano-composite functional powder involves selecting nano ceramic powder with a particle size of 30-60 nm, and performing surface activation treatment on the nano-ceramic powder to obtain activated nano-ceramic powder. The surface modification of activated nano ceramic powder is carried out, and dispersed the activated nano ceramic powder in absolute ethanol. A ceramic powder dispersion is obtained after full infiltration. The absolute ethanol and dispersant are taken to mix, after mixing, used high-speed shear to stir to obtain emulsion. The ceramic powder dispersion and the emulsion are mixed, stirred, and dried to obtain a modified activated nano ceramic powder. The formaldehyde is used as a reducing agent to silver-plated the modified activated nano-ceramic powder under room temperature and ultrasonic conditions to obtain nano-level silver-plated ceramic powder. The chitin fiber, graphene fiber and zinc oxide fiber are soaked in the coupling agent dispersion to generate antibacterial material. A composite antibacterial material powder with uniform particle size is prepared after drying and grounding. The nano-scale silver-plated ceramic powder, nano-scale zirconia ceramic powder, nano-scale zinc oxide ceramic powder, composite antibacterial material powder and hydroxyl-containing small molecule polymer are mixed. An antistatic and antibacterial nano-composite functional powder is obtained after drying.
