Abstract
A method for preparing a wood preservative composition, includes modifying lignin with NaBOor NaNOand then with a chromium (II) salt, copper (II), cadmium (II) or zinc (II), for example, metal nitrates (Cr(NO), Cu(NO), Cd(NO), Zn(NO)); to the preservative obtainable by this method; and to a method for preserving wood; and to the preserved wood. The preservative prevents degradation by xylophagous and fungal agents, and also improves some properties of the wood, and the hygroscopicity and fire resistance.
