COMPOSITION FOR WOOD PRESERVATION (OPTIONS) Russian patent published in 2022 - IPC B27K3/52 

FIELD: woodworking industry.

SUBSTANCE: inventions group relates to the woodworking industry, in particular to the impregnation of wood. The first version of the composition for wood preservation includes a fraction of light vacuum gas oil - a base that boils away in the range of 360-460°C, a narrow fraction of light ones - a diluent that boils out in the range of 230-360°C, and a fungicide - a product of the interaction of copper or zinc metal salts with saponified naphthenic acids - naphthenates and/or resinates of metal salts of copper or zinc. As a biocide contains a derivative of 2-aminothiazole in the following ratio, wt.%: fraction of light vacuum gas oil 5.0-55.0, narrow fraction of light 40.0-94.5, fungicide 0.4-5.0, biocide 0.1-1.0. The second version of the composition includes, wt.%: fraction of heavy vacuum gas oil 5.0-45.0, narrow fraction of light 50.0-94.5, fungicide 0.4-5.0, biocide 0.1-1.0. The third version of the composition includes, wt.%: fraction of dark vacuum gas oil 5.0-35.0, narrow fraction of light 60.0-94.5, fungicide 0.4-5.0, biocide 0.1-1.0. The fourth version of the composition includes, wt.%: fuel oil fraction 5.0-40.0, narrow light fraction 55.0-94.5, fungicide 0.4-5.0, biocide 0.1-1.0.

EFFECT: increases the microbiological stability of the impregnating composition.
