Embodiment 1

[0023] according to figure 1 As shown, this embodiment proposes a preparation process for antistatic and antibacterial nanocomposite functional powders, including the following steps:

[0024] Step 1: Select nano-ceramic powder with a particle size of 30nm, and perform surface activation treatment on the nano-ceramic powder, specifically: roughen the surface of the nano-ceramic powder to form countless micropores on the surface of the nano-ceramic powder , grooves, so that the surface of the nano-ceramic powder changes from a hydrophobic surface to a hydrophilic body, and then absorb a layer of divalent tin compound on the surface of the nano-ceramic powder in the roughened nano-ceramic powder sensitization solution (such as SnCl2) , and then undergo a hydrolysis reaction to complete the sensitization treatment, and finally immerse the sensitized nano-ceramic powder in an activation solution (such as palladium chloride) to be activated to obtain an activated nano-ceramic powde...

Abstract

The invention discloses a preparation process of antistatic and antibacterial nano composite functional powder. The preparation method comprises the following steps that surface activation treatment is carried out on nano-ceramic powder, surface modification is carried out on the activated nano-ceramic powder, silver plating treatment is carried out on the modified activated nano-ceramic powder, chitin fibers, graphene fibers and zinc oxide fibers are soaked in a coupling agent dispersion liquid, composite antibacterial material powder with uniform particle size is prepared, and all the powderis mixed with a hydroxyl-containing micromolecular polymer to obtain composite functional powder. The composite functional powder is prepared from nanoscale silver-plated ceramic powder, nanoscale zirconium oxide ceramic powder, nanoscale zinc oxide ceramic powder, chitin fibers, graphene fibers and zinc oxide fibers, and the prepared composite functional powder has antistatic, antibacterial, anti-infrared and anti-ultraviolet effects; and when the composite functional powder is applied to the textile fabric, the textile fabric can further have the functions of static electricity, bacteria resistance, infrared resistance and ultraviolet resistance.

Description

technical field [0001] The invention relates to the technical field of composite material production, in particular to a preparation process of antistatic and antibacterial nano composite functional powder. Background technique [0002] With the continuous development of science and technology and the continuous strengthening of human self-protection awareness, people have clearly realized that the skin is a weak link of the human body. The channel is therefore a line of defense that must be paid attention to. In recent years, the incidence of skin diseases has been increasing. The research results show that more harmful bacteria and viruses come into contact with the human skin, and the bacteria and viruses carried by the human skin can infect themselves and even the surrounding people, thus causing diseases. spread. [0003] Most of the functional textile fabrics currently on the market are prepared after functional finishing. The textile fabrics are finished with antist...
