摘要： 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.

摘要： A process for treating a wood substrate with a water-based formulation containing a wax in order to confer water repellency to the substrate comprising the steps of: (a) placing the substrate in a treatment vessel and reducing the pressure in the vessel to remove air in the pores of the substrate; (b) contacting the substrate in the vessel, while reduced pressure is present in the vessel, with the formulation to allow the formulation to flow into said pores, said contacting being carried out at a temperature at or above that required to cause the wax to change into a molten state; (c) applying a positive pressure to the vessel to force ther formulation into said pores; and (d) releasing the pressure in the vessel and removing the resultant wood substrate from the vessel.

摘要： Water-based wax emulsions, optionally for use in conjunction with alkaline copper and/or quaternary ammonium based preservatives systems, are described. These emulsions are comprised of natural or synthetic wax, nonionic surfactants having HL B values greater than 11, anionic surfactants, and water. Certain emulsion compositions as described in this specification posses the unique property of maintaining emulsion stability in wood preservatives during extended use in typical wood treatment processes. Water-repellant wood treated with the wax emulsions are described. A method of treating wood, comprising providing wood and treating the wood with the wax emulsion under conditions effective to increase its water repellency is also disclosed.

摘要： A process for treating wood involving impregnation of the wood with a preservative followed by the heat-fixation of the preservative in the wood using a pre-heated aqueous heat tansfer fluid to effect the heat fixation of the preservative. The process particularly relates to steps which are taken to reduce the level of any contamination of the aqueous heat transfer fluid resulting from any wood extractives, any unfixed preservative and/or any particulate matter (i.e. 'sludge') that may be present in the fluid. The contamination is preferably reduced by incorporating in the heat transfer fluid an oxidant which will preferentially oxidize any wood extractives resulting from the contact of the treated wood with the fluid without any significant reaction occurring between the oxidant and the preservative. Useful oxidants include inorganic chlorate salts such as sodium chlorate.
