Abstract[English]
Disclosed in the present invention are a long-acting antimicrobial and antiviral building coating and a preparation method therefor. The building coating is formed by mixing an inorganic antimicrobial material, a cationic resin emulsion, a pigment, an inorganic filler, deionized water, a dispersing agent, a defoaming agent, a thickening agent, and a film-forming auxiliary. The present invention exhibits a safe, efficient and broad-spectrum antimicrobial and antiviral effect by means of a synergistic effect of various components using the inorganic antimicrobial material as a functional filler, and shows long-acting and fast antimicrobial and antiviral characteristics using the cationic resin emulsion as a film-forming material. The obtained antimicrobial and antiviral building coating requires a small addition amount of an antimicrobial agent, can maintain the antimicrobial effect for a long time, satisfies the need for safe, environmentally friendly, and long-acting effects, and is suitable for building exterior walls and indoor coating applications.[French]
La présente invention divulgue un revêtement de construction antimicrobien et antiviral à action prolongée et son procédé de préparation. Le revêtement de construction est formé par mélange d'un matériau antimicrobien inorganique, d'une émulsion de résine cationique, d'un pigment, d'une charge inorganique, d'eau désionisée, d'un agent de dispersion, d'un agent antimousse, d'un agent épaississant et d'un auxiliaire filmogène. La présente invention présente un effet antimicrobien et antiviral sûr, efficace et à large spectre au moyen d'un effet synergique de divers composants à l'aide du matériau antimicrobien inorganique en tant que charge fonctionnelle, et présente des caractéristiques antimicrobiennes et antivirales à action prolongée et rapides à l'aide de l'émulsion de résine cationique en tant que matériau filmogène. Le revêtement de construction antimicrobien et antiviral obtenu nécessite une petite quantité d'addition d'un agent antimicrobien, peut maintenir l'effet antimicrobien pendant une longue période, satisfait la nécessité d'effets sûrs, respectueux de l'environnement et à action prolongée, et est approprié pour construire des parois extérieures et des applications de revêtement intérieur.[Chinese]
