| 摘要 |
A method for treating wood, characterised by impregnating wood with a metal-containing treating agent containing lignin and/or lignin derivatives and a metal, a metal compound, and/or a metal ion and oxidising and/or macromolecularising of the lignin and/or lignin derivatives in the wood to fix the metal component in the wood, and wood and woody materials obtained by the treating method. According to the method, while effectively utilising lignins, lignosulfonic acids, or lignosulfonic acid salts, leaching of the metal component can be suppressed to a low level to thereby retain the effects due to the incorporation of the metal components for a prolonged period. |
