Coating compound made of an agent which generates SiO2 with at least two antibacterial agents

摘要

Antibacterial coating composition comprises a silicon dioxide producing agent (50-99.9 wt.%, preferably 80-99 wt.%) and at least an antibacterial active substance (0.1-50 wt.%, preferably 1-20 wt.%), where the antibacterial active substance is at least two compound in the form of cationic, anionic or nonionic deactylated chitosan or its derivatives; phenols groups of the halogenated dihydroxydiphenylmethane, sulfide and ethers; and/or substituted quaternary ammonium salts of alkylated phosphoric acid. Independent claims are included for: (1) the preparation of the antibacterial coating comprising forming a sol gel with nanoparticles by hydrolysis of precursor in water; and providing antimicrobial active substance dissolved in a hydrophilic solvent to the brine solution; (2) an application kit comprising the composition together with application instruction panel for cleaning and preparation of the substrates to be coated, in the form of individually packed sachet cloths; and (3) a nano-scalic antibacterial coating in a thickness of 50-500 nm, preferably 120-250 nm, comprising a non-porous inorganically polymerized silicon dioxide layer, which is applied on a substrate, and an antibacterial active substance.
