Problems solved by technology

Some resins have poor wear resistance and some have friction in the use environment, which often causes the paint film to wear out and lose its function; on the other hand, because polymer materials are mostly insulating materials, static electricity is often generated in a dry environment. greater harm, even danger; and because of the humid and hot environment, etc., the paint film will be overgrown with enzymes and bacteria

Embodiment 1

[0015] Preparation of silver-loaded carbon nanotubes: add sodium hydroxide aqueous solution to 0.001mol / L silver nitrate solution, stir and drop dilute ammonia water, and after the precipitate is dissolved, silver ammonia solution is obtained, and the obtained silver ammonia solution is obtained at 40°C. The ammonia solution was evenly sprayed onto the surface of the carbon nanotube powder by spraying. After the surface of the carbon nanotube powder was completely wetted, the metered acetaldehyde was quickly sprayed onto the surface of the carbon nanotube in the same spraying manner, and left to stand for 1 Minutes to obtain carbon nanotubes with silver loaded on the outer surface;

[0016] Preparation of silver-loaded polyaniline nanofibers: Add sodium hydroxide aqueous solution to 0.001mol / L silver nitrate solution, stir and drop dilute ammonia water, and after the precipitate is dissolved, silver ammonia solution is obtained. At 40°C, the obtained The silver ammonia solutio...

Abstract

The invention discloses a preparation method of antibacterial anti-static paint. The paint adopts polyaniline nanofibers carried with silver on the surfaces, and meanwhile is combined with carbon nanotubes carried with silver on the sur4faces, so that the conductivity of the paint is increased, and the paint is good in antibacterial property and rub resistance; the silver is carried in a special sprayed manner, so that the silver nearly covers the surfaces of polyaniline nanofibers and the carbon nanotubes, and thereby the antibacterial property and conductivity is increased, and meanwhile the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial and antistatic coating. Background technique [0002] The common traditional paints in the market are made of natural resin or synthetic resin as the base material, and then add various pigments, various fillers, additives and solvents through mechanical processing. Some resins have poor wear resistance and some have friction in the use environment, which often causes the paint film to wear out and lose its function; on the other hand, because polymer materials are mostly insulating materials, static electricity is often generated in a dry environment. There will be greater harm, even danger; and due to the humid and hot environment, etc., the paint film will be overgrown with enzymes and bacteria. Contents of the invention [0003] The object of the present invention is to provide a kind of antibacterial and antistatic coating concurrently, have prepared polyaniline nanofiber and car...
