Abstract[English]
An antibacterial paint composed of a water-based paint functionalized by metallic nanoparticles that is used on wall supports to target bacteria, pathogenic strains, and nosocomial infections. Metallic silver (Ag) nanoparticles with average diameters of 83 nm synthesized by an aqueous method using PVA and an aqueous solution of silver ion. The water-based paint was created with a weight of titanium dioxide ranging between 7 and 12%, a weight of filler ranging between 25 and 35%, a weight of emulsion binder ranging between 30 and 40%, a weight of water ranging between 15 and 20 %, a weight of dispersing agent ranging between 0.3 and 0.5%, a weight of silicone antifoam agent ranging between 0.15 and 0.3 %, and a pH value ranging between 7.5 and 8.[French]
La présente invention concerne une peinture antibactérienne composée d'une peinture à base d'eau fonctionnalisée par des nanoparticules métalliques qui est utilisée sur des supports de paroi pour cibler des bactéries, des souches pathogènes et des infections nosocomiales. Des nanoparticules d'argent métallique (Ag) ayant des diamètres moyens de 83 nm synthétisés par un procédé aqueux utilisant du PVA et une solution aqueuse d'ion argent. La peinture à base d'eau a été créée avec un poids de dioxyde de titane compris entre 7 et 12 %, un poids de charge compris entre 25 et 35 %, un poids de liant d'émulsion compris entre 30 et 40 %, un poids d'eau compris entre 15 et 20 %, un poids d'agent de dispersion compris entre 0,3 et 0,5 %, un poids d'agent antimousse à base de silicone compris entre 0,15 et 0,3 % et une valeur de pH comprise entre 7,5 et 8.
