Abstract RU 2362671 C2

FIELD: technological processes.

SUBSTANCE: invention is related to composition for wood treatment and method of its production. Composition for wood treatment represents one common solution, which is the mixture of the first solution containing sterol, initiator and divinylbenzene as coupling agent mixed with the second solution, comprising furfuryl alcohol and initiator, where initiator of the first solution represent combination 2,2'-azobis(2-methylbutane nitrile) in amount of around 0.3 wt % relative to sterol, 1,1'-azobis(cyclohexanecarbonitrile) in amount of around 0.4 wt % relative to sterol and tret-butylperbenzoate in amount of 0.5 wt % relative to sterol, and initiator of the second solution represents maleic anhydride in amount from 5 to 10 wt % relative to furfuryl alcohol. Also method is described to produce composition for wood treatment and wood material treated by above-described composition.

EFFECT: production of wood-polymer composite material with high hardness, high moisture stability and resistance to biological decay.
