Abstract

The invention discloses a furfuralcohol polymer impregnated wood material and a preparation method thereof. The furfuralcohol polymer impregnated wood material is prepared by impregnating a wood material with use of a polymerizable furfuralcohol monomer mixture; the mixture consists of the following components in percentage by weight: 50% to 85% of water, 10% to 28% of furfuralcohol, 1% to 9% of nanometer calcium carbonate, 2% to 8% of a stabilizing agent and 0.5% to 5% of an initiator, wherein the stabilizing agent is selected from a group consisting of sodium carbonate, sodium bicarbonate, sodium citrate and sodium phosphate; the initiator is selected form a group consisting of citraconic anhydride, malic acid and palmitic acid.

Description

technical field [0001] The invention relates to the field of wood processing, in particular to wood impregnated with furfuryl alcohol polymer and a preparation method thereof. Background technique [0002] Modified wood is produced by first impregnating a wood sample with an appropriate amount of a polymerizable liquid and, after impregnation, heating the wood sample so that the polymerizable compound is polymerized in the wood cell walls. [0003] The mechanism of wood impregnation is to impregnate low-molecular-weight resins into wood. Under certain conditions, the resins polymerize with each other, or form hydrogen bonds or chemical bonds with hydroxyl groups in wood, and generate insoluble polymers in the cell wall. The number of hydroxyl groups in the wood reduces the hydrophilicity of the wood, thereby resisting the adsorption of water by the cell wall; the resin polymer changes the swelling and expansion of the cell wall to resist the shrinkage of the cell wall; in ad...
