Patent

CA 2580079

There are provided compositions for the preservation of wood and related cellulosic and lignocellulosic materials. The wood preservative compositions of the present invention contain an organic preservative agent and an organic acid, and can be solubilized in an organic phase essentially free of volatile organic compounds (VOC). The organic acids may serve various purposes in the compositions of the present invention: (1) increased preservative solubility in the organic phase, (2) improved distribution gradient of the active preservative in treated wood, or (3) reduction of preservative leaching.

L'invention concerne des compositions destinées à préserver le bois et les matériaux cellulosiques et lignocellulosiques dérivés. Les compositions de préservation du bois de la présente invention contiennent un agent de préservation organique et un acide organique, et peuvent être solubilisées dans une phase organique ne contenant essentiellement pas de composés organiques volatils (VOC). Les acides organiques peuvent avoir divers usages dans les compositions de la présente invention: (1) une solubilité supérieure de l'agent de préservation dans la phase organique, (2) un gradient supérieur de distribution de l'agent de préservation actif dans le bois traité, ou (3) une réduction de lixiviation de l'agent de préservation.
