WOOD MODIFIER, PREPARATION METHOD THEREOF AND METHOD FOR MODIFYING WOOD USING THE SAME

摘要

Disclosed are a wood modifier, preparation method thereof and method for modifying wood using the same. The modifier comprises sodium montmorillonite (Na-MMT), quaternary ammonium salt and dispersant polyethylene glycol (PEG). In the preparation method, Na-MMT, quaternary ammonium salt and PEG are mixed and dispersed so as to obtain the final product. After the wood being subjected to impregnating process, complex reaction among MMT, quaternary ammonium salt and PEG occurs to produce complex compound which combines with the hydroxide radicals in the cellulose, hemi-cellulose and lignin in the wood during the impregnating process, so as to improve the dimensional stability and mechanical strength of the wood, effectively upgrade the superficial hardness, compression strength, leach resistance. The modified wood has a better performance.
