Antibacterial coating liquid as well as preparation method and application thereof

Abstract

The invention belongs to the technical field of antibacterial coating preparation, and particularly relates to antibacterial coating liquid as well as a preparation method and application thereof. The antibacterial coating liquid is prepared from the following raw materials: an organic antibacterial agent, an inorganic antibacterial agent, alcohol ester-12, emulsified methyl silicone oil, allyl-3-methylimidazolium chloride, silicone acrylic emulsion and water; wherein the organic antibacterial agent is a mixture of N-[(2-hydroxy-3-trimethylamine) propyl] chitosan chloride, polyhexamethylene guanidine hydrochloride, dodecyl guanidine monohydrochloride, isothiazolinone and salicylanilide; and the inorganic antibacterial agent is a mixture of modified nano zinc oxide and nano cerium oxide. According to the antibacterial coating liquid disclosed by the invention, the organic antibacterial agent and the inorganic antibacterial agent are added into the silicone acrylic emulsion, and the organic antibacterial agent and the inorganic antibacterial agent are compounded for use, so that the prepared antibacterial coating liquid is remarkable in antibacterial effect, lasting in effect, stable in performance and low in toxicity, and the application range is widened.

Description

technical field [0001] The invention belongs to the technical field of antibacterial coating preparation, and in particular relates to an antibacterial coating liquid and its preparation method and application. Background technique [0002] In some aseptic production workshops or laboratories in biochemical and other industries, the decorative materials used for the interior and exterior walls are common plates or facing bricks. Common plates or facing bricks are not only rough in surface, easy to stick to dust, but also easy to breed harmful bacteria. It pollutes the environment and is harmful to health. At the same time, it has poor weather resistance, short service life, easy damage, and fails to achieve the expected effect. [0003] Coated steel plate is an emerging material, which has the advantages of strong corrosion resistance, long service life, convenient processing and forming, low production investment cost, and low environmental pollution. It is widely used in c...

Problems solved by technology

[0005] However, photocatalytically active substances usually have specific light wavelength absorbing groups, 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 Antibacterial coating needs to be developed and applied to antibacterial boards. At present, there are almost no real antibacterial board products in the domestic market, so it is of great significance to develop antibacterial boards with real antibacterial properties
