example 1

[0025] Mix montmorillonite and marble at a mass ratio of 2:3, put them into a pulverizer and pulverize for 1 hour, pass through a 150-mesh sieve after pulverization, and collect the sifted powder; According to the mass ratio of 2:1:1, the mixture is obtained and added to the fermenter, and the concentration of 7% of the mixture mass is added at the same time as 10 7 cfu / mL yeast suspension, seal the fermenter, and adjust the temperature in the fermenter to 30°C, and ferment for 2 weeks, the obtained fermentation product is the modified inorganic mineral, ready for use; Add ammonia water with a concentration of 0.8mol / L into the solution until the precipitate is completely dissolved to obtain a cuproammonia solution. The obtained cuproammonia solution is mixed at 38°C at a rate of 2mL / cm 2 Spray the cuproammonia solution onto the surface of the carbon nanotube powder. After the surface of the carbon nanotube powder is completely wetted, quickly spray the cuproammonia solution a...

[0027] Mix montmorillonite and marble at a mass ratio of 2:3, put them into a pulverizer and pulverize for 1.5 hours, pass through a 150-mesh sieve after pulverization, and collect the sifted powder; The sugar is mixed according to the mass ratio of 2:1:1 to obtain the mixture and added to the fermenter. At the same time, the concentration of 8% of the mass of the mixture is 10 7 cfu / mL yeast suspension, seal the fermenter, and adjust the temperature in the fermenter to 35°C, and ferment for 2 weeks, the obtained fermentation product is the modified inorganic mineral, ready for use; Add ammonia water with a concentration of 0.8mol / L to the solution until the precipitate is completely dissolved to obtain a cuproammonia solution. The obtained cuproammonia solution is heated at 39°C at a rate of 2mL / cm 2Spray the cuproammonia solution onto the surface of the carbon nanotube powder. After the surface of the carbon nanotube powder is completely wetted, quickly spray the cuproammoni...

Abstract

The invention discloses a preparation method of antibacterial and antistatic coating and belongs to the technical field of coating preparation. The preparation method disclosed by the invention has the beneficial effects that montmorillonite and marble contain a large amount of metal oxides such as MgO, CaO and ZnO and the like, the metal oxides are inorganic antibacterial agent and are also goodconducting materials; both tea polyphenol and houttuynin have antibacterial and antiseptic effects, and by the fermenting action, the tea polyphenol and the houttuynin can be combined with inorganic minerals; compared with polyanilines with other structures, the polyaniline with a nanofiber structure has higher conductivity; carbon nanotubes have good mechanical property and electric property simultaneously, and by combination of polyaniline nanofiber with the copper-loaded surface and the carbon nanotubes with the copper-loaded surfaces, the conducting property of the coating is improved, simultaneously the coating has good antibacterial property and wear resistance; by adoption of a special spraying mode for loading copper, the copper can be almost loaded on the surfaces of the polyaniline nanofiber and the carbon nanotubes, so that the antibacterial property and the conducting property are improved and the preparation cost is greatly reduced.

Description

technical field [0001] The invention discloses a preparation method of an antibacterial and antistatic paint, which belongs to the technical field of paint preparation. Background technique [0002] The names of conductive coatings include antistatic coatings and antistatic coatings. According to a series of standards formulated by the country, conductive coatings are used. From the design of industrial buildings and equipment, conductive coatings are used. From the functional analysis of coatings, the coating can be used in 10~ In a short period of 20 seconds, discharge static voltage accumulation to avoid accidents that cause fire or damage electronic components due to discharge. The generation and accumulation of static electricity is an objective existence in nature and has no resistance skills. It has not been tested for fabrics. The antistatic agent product based on the theory of leakage can prevent the accumulation of static electricity during the wearing process of c...
