Abstract

The invention provides a novel antibacterial coating and a preparation and application method thereof. The novel antibacterial coating comprises an aqueous polyurethane emulsion, a pure acrylic emulsion, chlorhexidine digluconate, halogenated alkyl thiosulfonamide, 2-amino-2-methyl-1-propanol, an oxidized polyethlene wax emulsion, mixed dibutyl dibasic acid ester, alkyl polyoxyethylene ether, organic montmorillonite, talcum powder, a dispersant, a wetting agent, a defoamer and water. The novel antibacterial coating has the advantages of reasonable composition, good product stability and good pigment wettability, improves coating hiding power and scrub resistance of interior wall paint, makes the film feel more slippery, improves outdoor color retention of the coating through a special polymer form, improves emulsion compatibility, reduces an emulsion use amount and saves a cost.

Description

technical field [0001] The invention belongs to the field of paint production, and in particular relates to a novel antibacterial coating, a preparation method and an application method of the novel antibacterial coating. Background technique [0002] Generally speaking, paints and coatings are materials that can be coated on the surface of the object to be coated and form a continuous thin film that adheres firmly, whether it is a traditional coating product that uses natural substances as raw materials or a synthetic chemical product that is currently developing. The coating products of raw materials are all organic chemical polymer materials, and the formed coating film belongs to the type of polymer compound. According to the classification of modern chemical products, coatings belong to fine chemical products, and modern coatings are gradually becoming a class of multifunctional Engineering materials are an important industry in the chemical industry. [0003] In moder...
