FIELD: woodworking industry.
SUBSTANCE: invention relates to woodworking industry, in particular, to wood protection preparations. Difficult leaching water-soluble preparation for wood protection contains compounds of chromium, copper and fluorine - boron hydrofluoric acid or hydrofluorosilicic acid, with following ratio of components: (0.4–1.3):(0.6–1.5):(0.3–0.9) in terms of Fluorine F(I): Chromium Cr(VI): Copper Cu(II). To hydrofluorosilicic acid additionally introduced is sodium tetraborate Na2B4O7·10H2O or potassium tetraborate, and the composition with hydrofluorosilicic acid additionally introduces either sodium orthosilicate Na4SiO4 or sodium metasilicate Na2SiO3 or ammonium orthosilicate (NH4)4SiO4 or ammonium metasilicate (NH4)2SiO3, depending on the anionic composition of the preparation in amount from 0.3 % to 4 %.
EFFECT: reduced rate and degree of hydrolysis, high pH, reduced rate of de-conservation of wood.
