Title (EN) WOOD PRESERVATIVE COMPOSITION
(FR) COMPOSITION DE PRESERVATION DU BOIS
Abstract:
(EN) An aqueous wood preservation composition containing inorganic polymers of one or more of the following metals is disclosed; aluminum (approximately 3.8% - 7.0% as Al203), zirconium (approximately 5.25% - 9.1% as ZrO2), copper (approximately 0.7% - 8.8% as CuO) and a fixing agent such as acetic acid or sodium acetate. The pH is adjusted to be between 2.0 - 4.0 using an inorganic base such as copper carbonate. The invention includes wood and cellulose fibers treated by the composition of the present invention as well as methods of preserving wood and cellulose fibers using the compositions.
(FR) L'invention concerne une composition de préservation du bois aqueuse contenant des polymères inorganiques d'un ou plusieurs des métaux suivants : aluminium (environ 3.8 % - 7.0 % si Al203), zirconium (environ 5.25 % - 9.1 % si ZrO2), cuivre (environ 0.7 % - 8.8 % si CuO) et un agent fixateur, tel qu'un acide acétique ou de l'acétate de sodium. Le pH est ajusté de manière qu'il soit compris entre 2,0-4,0 au moyen d'une base inorganique, telle que le carbonate de cuivre. L'invention porte également sur des fibres de bois et de cellulose traitées par la composition de l'invention, ainsi que sur des méthodes de préservation de fibres de bois et de cellulose au moyen desdites compositions.
