FIELD: wood-working industry.
SUBSTANCE: described is the wood impregnated with furan polymer obtained by impregnation of wood with solution of polymerized monomer of furfural alcohol containing water, stabilizers in the form of borax and sodium salts of lignosulfone acids, furfural alcohol and at least one additional compound selected from maleic anhydride, phthalic anhydride, maleic acid, phthalic acid and their combinations. Described also is the method of wood treatment by single-stage impregnation with a solution of polymerized monomer of furfural alcohol, subsequent hardening at a temperature of 70-140C providing drying in an oven.
EFFECT: enhanced stability of dimensions in the conditions of varying moisture content, enhanced hardness and resistance to putrefaction.
