The specification describes preserved solid wood or wood composites including a copper ammonium acetate complex wood preservative and a drying oil. The wood preservative is present in the wood in an amount effective to improve the resistance of the treated wood to at least one type of decomposition, such as decay or insect attack. The drying oil is present in the wood in an effective amount to accomplish at least one useful end, such as reducing the water absorption or thickness swell of the treated wood or increasing its mechanical strength, even in a wood composite made using less binding resin than usual. Yet another aspect of the invention is a method of making the treated wood from green wood in solid or flaked form. A copper ammonium acetate complex wood preservative and optionally a drying oil are added to the green wood.

A fire-retardant wood-based composite is formed by treating a green wood furnish with an amount of a phosphate/borate fire retardant treatment effective to increase the fire retardancy of the resulting wood-based composite, compared to the fire retardancy of the corresponding wood-based composite lacking the fire retardant. The fire retardant treated green wood furnish is blended with a binder and then bound, as by pressing the furnish, to form a non-leaching fire-retardant wood based composite. Another aspect of the invention is the product formed according to the preceding process. The fire retardant may also act as a catalyst to cure the binder and thus promote binding. Also, the addition of the fire retardant to green wood chips, without the need to dry them to a low moisture content, is believed to be novel.

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.

A treated wood-based composite is formed by treating a green wood furnish with an amount of a treating agent effective to increase the value of the resulting wood-based composite. The treating agent can be, for example, a fire retardant, a wood preservative, a dye, a pigment, a stain, bleach, a water repellant, a drying oil, or a combination thereof. The treated green wood furnish is blended with a binder and then bound, as by pressing the furnish, to form a non-leaching fire-retardant wood based composite. Another aspect of the invention is the product formed according to the preceding process. The addition of the treating agent to green wood chips, without the need to dry them to low moisture content, is believed to be novel.

A composition is disclosed comprising a long-chain quaternary ammonium compound and a wood preservative active agent or a mixture thereof. The long-chain quaternary ammonium compound includes at least one alkyl moiety having from 16 to 50 carbon atoms, unsubstituted or substituted with one or more N, O, S, or halogen atoms. A method of treating wood is disclosed, comprising impregnating wood with the above composition in an amount effective to reduce the preservative active ingredient loss in the treated wood or to increase the resistance of the wood to decay. Treated wood and wood products are disclosed comprising wood impregnated with the above composition, including a treatment level of the long-chain quaternary ammonium compound effective to reduce the preservative active ingredient loss in the treated wood or to increase the resistance of the wood to decay.

The invention is a wood composite including wood particles, a binder, at least one wood stabilizer, and optionally other ingredients. Examples of the wood stabilizer are an ammoniacal wood stabilizer or ammoniacal copper dimethyl glyoxime. The wood stabilizer is present in an amount effective to reduce the swelling value of the wood composite to less than that of an analogous wood composite not treated with the wood stabilizer. A method for making wood composites and the product of that method are also disclosed. The method includes providing green wood particles and applying to them a wood stabilizer as described above, preferably without an intervening drying step. It is contemplated that the wood stabilizer can be applied in an amount effective to at least substantially preserve the resulting wood composite against at least one of rot, termites, and carpenter ants. While or after applying the stabilizer, a water repellant material is applied to the wood particles. The treated wood particles are then formed into a wood composite.
