FIELD: chemistry.

SUBSTANCE: invention relates to biocides, polymers, composites and laminates. The biocidal composition contains an inorganic biocidal compound and at least one organic biocidal compound. The inorganic biocidal compound consists of at least one nanosized metal oxide selected from ZnO, BaTiO₃, SrTiO₃, TiO₂, WO₃, Akl₂O₃, CuO, NiO, ZrO₂ and MgO. The organic biocidal compound is selected from: isothiazolinones and isothiazolinone derivatives, phenol derivatives, bromic acid derivatives, formaldehyde and derivatives thereof, formaldehyde deposit products, guanidines, chlorine- and/or bromine-containing compounds, urea derivatives, benzyl alcohol, phenylethyl alcohol, dimethylol dimethyl hydantoin, glycosal, glutardialdehyde, sorbic acid and sorbates, benzoic acid and benzoates, 4,4-dimethyl-1,3-oxozolidine, derivatives of 1,3,5-hexahydrotriazine, quaternary ammonium compounds, cetyl pyridinium chloride, ethylene glycol hemiformal, salt of tetra-(hydroxymethyl)-phosphonium, 3-iodo-2-propynyl-N-butylcarbamate, methyl-N-benzimidazo-2-ylcarbamate, 2,2-dithiodibenzoic acid-di-N-methylamide, 2-thiocyanomethylthio benzothiazole, C-formal, methylene bisthiocyanate, lysozyme (E1105), nisin (E234), natamycin (E235), hexamethylene tetramethrin (E239), dimethyl dicarbonate (E242), propionic acid and propionates, and ethylene disodium methylene diamine tetraacetate. The polymer composition, composite material or laminate contain the biocidal composition.

EFFECT: invention enables to obtain materials with biocidal effect and which can be stored at high temperatures.
