The present invention provides a solution and related composition of matter and methods which synergistically improves a fungicide's effectiveness in resisting undesired fungal growth. The invention also provides wood and wood products which have been treated with the solution, method or compound.

Provided is a composition for the preservation of wood and other cellulosic materials. The composition comprises a dispersion of micronized inorganic compounds and/or organic biocides in an organic carrier. Also provided is a method for making the composition.

The present invention provides wood preservative compositions comprising micronized particles. In one embodiment, the composition comprises dispersions of micronized metal or metal compounds. In another embodiment, the wood preservative composition comprises an inorganic component comprising a metal or metal compound and organic biocide. When the composition comprises an inorganic component and an organic biocide, the inorganic component or the organic biocide or both are present as micronized particles. When compositions of the present invention are used for preservation of wood, there is minimal leaching of the metal and biocide from the wood.

The present invention relates to furniture panels, and more particularly, to a method for preparing functional engineered wood. It includes the following steps: make veneer blanks by rotary cutting or splicing, and cut the veneer blanks into desired dimensions to obtain veneers A. Soak the veneers A in a ternary mixed solution of a biomass nanocellulose solubilizer, a fire retardant and an acid dye for toughening, fire retardation and dyeing to obtain veneers B. Add a formaldehyde decomposing powder into a modified MUF adhesive, mix them up, coat the veneers B with the mixture to obtain veneers C. Assemble and cold-press the veneers C to obtain flitches D, and saw the flitches D into desired patterns and dimensions to obtain finished products.

Methods for treating cellulosic materials comprising introducing a liquid treating composition into the cellulosic material, the treating composition comprising a solution prepared from at least: (i) one or more of a copper amine complex or copper ammine complex, such as copper tetraamine carbonate, (ii) one or more of ammonia or a water-soluble amine and (iii) water; and exposing the cellulosic material provided thereby to carbon dioxide and/or carbonic acid to provide treated cellulosic material, and treated cellulosic materials prepared thereby.

The present invention is directed to amine soluble, or solid copper triazole based wood preservative formulations containing certain types of quaternary ammonium compounds, or nonionic sufactants, and the use of these quaternary ammonium compound-, or nonionic surfactant-containing formulations to pressure treat and preserve wood. The addition of the quaternary ammonium compounds, or nonionic surfactants to the wood preservation treatment solutions allows improved penetration of the copper from the solution into wood and reduces the duration of time required to effectively pressure treat the wood with the preservation composition.
