A treatment process and wood products thereof including a product formulation of a single phase solution combining a wood preservative (durable component) with a Flame Retardant component (FR) to produce a durable Flame Retardant (dFR) treated wood product. The durable component comprises a range of copper based and non-copper based wood preservatives, while the FR component comprises alkali metal silicates and alkali metal aluminate compounds. The dFR working solution undergoes chemical impregnation (treatment) followed by a heat (fixation) process step that locks the chemical into the wood making it non-leachable. The dFR treated wood products are tested for their enhanced fire performance properties. When heated, wood undergoes thermal degradation and combustion producing gases, vapors, tars and chars. Using a cone calorimeter burn test method, dFR treated wood products show a significant reduction in heat release rate, mass loss rate and smoke generated values compared to untreated radiate pine.

A method for reinforcing and enhancing bamboo/wood materials employs a sulfuric acid hydrolysis method to prepare a nanocellulose dispersion solution; then with the nanocellulose dispersion solution having a certain concentration as a precursor, nano zinc oxide is in-situ produced on the surface of the nanocellulose; and the cellulose dispersion solution is improved by compounding. The obtained treatment solution is impregnated into the pores of bamboo/wood materials in a specific manner to play the role of filling, binding and consolidating the bamboo/wood tissues, so that the treated bamboo/wood materials have enhanced hardness, strength and dimension stability, and significantly-improved mildew- and corrosion-resistance. The method is suitable for the reinforcing and enhancing treatment of wood materials with relatively-loose texture, such as fast-growing wood and wood from a planted forest, and is also suitable for the reinforcement and restoration of slightly-rotten wood materials.

A synergistic aqueous wood preservative composition comprising a copper compound and penflufen. The copper compounds of the compositions of the invention may be soluble, partially solubilized or micronized particles. The penflufen of the compositions of the invention may be solubilized, emulsified or particulate. The wood preservative compositions of the present invention are surprisingly provided as stable dispersions and confer surprising and unexpected resistance to treated wood and wood products.

Disclosed herein are compositions and methods for treating wood to give it a desirable color that is durable over time, while at the same time rendering the wood resistant to fungal decay and insect attack. The wood may be pressure treated in a two-step process whereby the wood is first treated with a wood preservation composition, and then treated with a composition comprising pigments, or vice versa. Alternatively, the wood may be simultaneously treated with a composition comprising a wood preservative and a composition comprising pigments.

This invention refers to a method for producing magnetic cork particles comprising the steps of providing a composition of an alkaline solution and cork particles, with a size comprised between 1 nm and 2 mm, and stirring; Adding an acid solution containing Fe.sup.3+ and Fe.sup.2+ cations to the composition to cause the magnetization of the cork particles and maintaining the stirring; Filtering the solution obtained to obtain a magnetized cork particles precipitate, and washing the precipitate with water until the washed solution reaches a pH comprised between 4 and 7, and let dry until obtaining stabilized magnetized cork particles, wherein the magnetization of the cork particles is due to the formation of a magnetite coating on the particles, being the magnetite adsorbed on the particle surface. It also refers to magnetized cork particles thus obtained and their uses.

A non-flammable composition is formulated to include ceramic powder, graphite, mica and ZrO.sub.2. The non-flammable composition is capable of being applied to an external surface of an item, or may be incorporated into the substrate material used to form an item prior to the item's manufacture. The non-flammable composition provides both fire-resistance and fire-retardant properties to the items that are treated thereby.

Wood preservative compositions comprising a particulate copper compound in a solvent carrier with low aromatic content. Particulate copper dispersions in this composition demonstrated superior stability, and wood treated with the composition is protected from attack by wood decay fungi and termites. The invention is also directed to wood preservative compositions comprising: (a.) a biodegradable organic solvent carrier selected from the group consisting of vegetable oil, renewable resource oil, and biodiesel; (b.) a dispersion of solid particles of a metal compound having a particle size between about 0.005 microns to about 10 microns; (c.) an organic biocide; and (d.) a dispersant; ratio of the dispersant to the metal compound is from about 1:500 to about 100:1 (wt/wt). The invention is also directed to compositions comprising penflufen and solvent carriers. The invention is also directed to methods of treating wood using the compositions, and wood treated with the disclosed compositions and methods.

A flexible structure is formed by subjecting cellulose-based natural wood material to a chemical treatment that partially removes hemicellulose and lignin therefrom. The treated wood has a unique 3-D porous structure with numerous channels, excellent biodegradability and biocompatibility, and improved flexibility as compared to the natural wood. By further modifying the treated wood, the structure can be adapted to particular applications. For example, nanoparticles, nanowires, carbon nanotubes, or any other coating or material can be added to the treated wood to form a hybrid structure. In some embodiments, open lumina with-in the structure can be at least partially filled with a non-wood substance, such as a flexible polymer, or with entangled cellulose nanofibers. The unique architecture and superior properties of the flexible wood allow for its use in various applications, such as, but not limited to, structural materials, solar thermal devices, flexible electronics, tissue engineering, thermal management, and energy storage.
