Problems solved by technology

The commonly used inorganic antibacterial materials on the market are nano-silver, complexes of nano-silver, and nano-titanium dioxide. Nano-silver sterilizes bacteria because of the surface effect, quantum size and quantum tunneling effect of nano-silver, which makes nano-silver have super activity and permeability. Moreover, the surface characteristics of nanoscale metallic silver can form ligands with electron-withdrawing groups such as sulfhydryl groups and amine groups of

Embodiment 1

[0024]

[0025] The preparation method of the inorganic antibacterial and aldehyde-removing coating is as follows:

[0026] (1) At a rotational speed less than 500r / min, add water, hydroxyethyl cellulose, and pH adjuster in turn to disperse for 1-3 minutes.

[0027] (2) Increase the speed to 800-1000r / min, add wetting agent, dispersant, defoamer, titanium dioxide, calcined soil, calcium carbonate, talcum powder, nano-zinc oxide dispersion in sequence, and increase the speed to 1800-2000r / min min, disperse for 15-20min.

[0028] (3) Reduce the rotating speed to 1000-1200r / min, add emulsion, film-forming aid, antifreeze and thickener in sequence, disperse for 10-15min, and sieve through 200 mesh to obtain the product of the present invention. The antibacterial rate of this formula coating against Staphylococcus aureus, Escherichia coli and Candida albicans is 99.87%, the mildew resistance level against mold is 0, the purification rate of formaldehyde is as high as 91%, and t...

Abstract

The invention relates to an inorganic antibacterial formaldehyde-removing paint. The antibacterial formaldehyde-removing paint is prepared by using an emulsion as a binding agent and an inorganic antibacterial functional material nanometer zinc oxide as a functional material. The inorganic antibacterial formaldehyde-removing paint comprises the following components: water, emulsion, nanometer zinc oxide, titanium dioxide, calcined clay, calcium carbonate, talcum powder, a wetting agent, a dispersant, an anti-foaming agent, a film-forming agent, an antifreezer and a thickener. Compared with traditional regular organic antiseptic and anti-mildew agents, the inorganic nanometer zinc oxide antibacterial and antiviral paint has the functions of safeness, no toxicity, long-term antisepsis and formaldehyde removal.

Description

technical field [0001] The invention relates to a preparation method of an inorganic antibacterial and aldehyde-removing coating. Background technique [0002] At present, water-based latex paints generally use organic fungicides and antifungal agents, the ingredients of which are isothiazolones, formaldehyde-releasing, benzoimidazoles, substituted aromatics, organic bromine, and dithiocarbamate, etc. . The sterilization and anti-mold of this kind of bactericide and anti-mold agent is to inactivate the germs and mold through its own toxicity, so as to achieve the purpose of anti-bacteria and anti-mold. These fungicides and antifungal agents are strongly irritating to the skin, potentially harmful to water organisms, sensitive to pH, not resistant to high temperatures, and because they are organic compounds, they will slowly decompose during use and become invalid. Organic preservatives will be lost in the paint film after being rinsed by rainwater, losing their antiseptic ...
