ANTIMICROBIAL-PROTECTED MATERIALS Russian patent published in 2014 - IPC B65D81/24 A01N25/12 A01N59/26 A01N59/20 A01N59/16 

FIELD: chemistry.

SUBSTANCE: antimicrobial-protected material and use of said material. The material consists of a matrix containing inorganic phosphates of at least two different metal cations, copper (Cu) and zinc (Zn), in finely dispersed, dispersed or dissolved form. The metal phosphates are selected from basic copper phosphate Cu₂(OH)PO₄, copper (II) phosphate Cu₃(PO₄)₂, copper (II) pyrophosphate Cu₃P₂O₇, zinc dihydrophosphate Zn(H₂PO₄)₂, zinc orthophosphate Zn₃(PO₄)₂ and zinc pyrophosphate Zn₂P₂O₇. The material forming the matrix is selected from organic polymer materials selected from polyvinyl butyral, polypropylene, polyethylene, polyamide, polybutylene terephthalate, polyethylene terephthalate, polyester, polyphenylene oxide, polyacetal, polymethacrylate, polyoxymethylene, polyvinyl acetal, polystyrene, a copolymer of acrylonitrile, butadiene and styrene, a copolymer of acrylonitrile, styrene and acrylate, polycarbonate, polyether sulphone, polyether ketone, polyvinyl chloride, thermoplastic polyurethane and/or copolymers thereof and/or mixtures thereof.

EFFECT: high antimicrobial activity while reducing the harmfulness of the antimicrobial agent.
