Abstract

The invention provides a long-acting antibacterial paint and preparation and application methods of the long-acting antibacterial paint. The long-acting antibacterial paint contains an organosilicon-modified acrylic emulsion, a polyhexamethylene biguanidine hydrochloride styrene-acrylic emulsion, benzethonium chloride, isothiazolin-3-ketone, 2-amino-2-methyl-1-propanol, a oxidized polyethlene wax emulsion, mixed dibasic acid dibutyrate, alkyl polyoxyethylene ether, diatomite, talcum powder, a dispersant, a wetting agent, an antifoaming agent and water. The long-acting antibacterial paint has reasonable components, has good product stability and film formation effect, has unique storage stability after paint formulation, leveling property and adhesion, can help increase gloss, has good antibacterial and bactericidal characteristics, and can kill bacteria and pathogen attached to a paint. In addition, the antibacterial material can be uniformly mixed with the paint, has good chemical stability, will not change chemical structure of the paint, and is long-acting and effective.

Description

technical field [0001] The invention belongs to the field of paint production, and in particular relates to a long-acting antibacterial paint, a preparation method and an application method of the long-acting antibacterial paint. 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.
