Problems solved by technology

[0003] However, photocatalytically active substances usually have a specific light wavelength absorption range, TiO 2 Nanoparticles have strong absorption strength and sterilizing activity for ultraviolet light, but weak absorption and activity under visible light, so they become hygienic corners in some corners that do not see sunlight. In order to solve this problem, more excellent performance Antimicrobial coatings need to be developed

Abstract

The invention relates to an antibacterial coating layer and a preparation technology thereof. The antibacterial coating layer comprises 0.01% to 0.05% of Fe3O4 (ferroferric oxide)-doped TiO2 (titaniumdioxide) nanoparticles, and also comprises a fluoride acrylic emulsion, an epoxy resin emulsion, melamine, carbodiimide, a talcum powder, sodium polymethacrylate, water-borne color paste, trimethyl hydroxyl amyl alcohol isobutyric acid ester, propylene glycol, a high fatty acid ester compound, titanium dioxide, polyoxyethylene alkyl phenol ether, 1,2-benzisothiazolin-3-ketone, alkanolamine and water. The antibacterial coating layer is mixed by the components. The Fe3O4-doped TiO2 (titanium dioxide) nanoparticle is prepared from Ti(SO4)2 (titanium sulfate), Fe3O4, ammonia water, sodium dodecylbenzene sulfonic acid, nitric acid, hydrochloric acid and water through co-precipitation. Compared with the antibacterial coating layer containing pure TiO2 nanoparticles, the antibacterial coating layer has the advantages that the absorption spectrum is broader; the strong bacteria inhibiting and killing activity is realized under the visible light; a smaller amount of nanoparticles is requiredin the production process, and the cost is obviously reduced.

Description

technical field [0001] The invention relates to the technical field of coatings, more specifically, to an antibacterial coating and a preparation process thereof. Background technique [0002] Antibacterial coating is a coating technology that has developed rapidly in recent years. Antibacterial coatings are used in medical places, which can significantly inhibit the spread of pathogenic microorganisms, which is of great significance to public health. In practical applications, photocatalytic semiconductors Nano material TiO 2 And ZnO is the most common. The principle of photocatalytic sterilization is that under the irradiation of ultraviolet light, a large number of hydroxyl radicals and oxygen free radicals are generated on the surface of photocatalytic semiconductor materials, which have strong and chemical activity, so that microorganisms can oxidize organic substances, thereby It can inhibit and kill microorganisms in contact with the coating film. Since the nanoparti...
