WOOD TREATMENT METHOD AND COMPOSITION Russian patent published in 2007 - IPC B27K3/32 B27K3/52 B27K3/08 C09D1/04 

FIELD: process for reducing of wood destruction rate by synthesizing and using non-toxic aqueous composition favorable for environment.

SUBSTANCE: method involves bringing wood into contact with aqueous alkaline colloid composition containing electrostatically charged particles of colloid-colloid silicon oxide comprising barium ions included therein, said contacting occurring under environmental temperature and pressure conditions or under elevated temperature and increased pressure conditions. Composition contains water, hydroxide of alkaline metal in an amount sufficient for bringing of water pH value to 10, silicon-containing salt, boron-containing salt, electrostatically charged particles of colloid silicon oxide, said particles containing boron ions included therein, and, optionally, aluminum halogenide and preservative. Composition is obtained by mixing components thereof. Method is provided under conditions causing production of oversaturated solution of boron-containing salt. Method allows quality of wood to be improved.

EFFECT: improved preservation of wood by increasing resistance thereof to insect, decay, ultraviolet damages, fires and other environmental effects.
