FIELD: impregnation of wood.
SUBSTANCE: the suggested wood should be obtained due to impregnating wood with the mixture based upon polymerized monomer of furfuryl alcohol that contains, at least, water, furfuryl alcohol, a stabilizer and an initiator, moreover, the stabilizer should be chosen out of sodium carbonate, sodium bicarbonate, sodium citrate, phosphates and water-soluble derivatives of lignin such as calcium and ammonium salts of ligninsulfonic acids, moreover, the mixture additionally contains the initiator chosen out of maleic anhydride, phthalic anhydride, maleic acid, malic acid, phthalic acid, benzoic acid, malonic acid, ascorbic acid, citric acid, zinc chloride, aluminum chloride, other cyclic organic anhydrides and acids and their combinations, at pH ranged 2.5-4.0. It has been, also, described the method for obtaining the wood impregnated with furan polymer due to impregnating the wood with the mixture based upon polymerized monomer of furfuryl alcohol followed by hardening at different temperature modes. The suggested wood is of high stability of sizes under conditions of altering moisture and increased resistance to rotting.
EFFECT: higher efficiency.
