The present invention relates to a method for preparing a wood modifier and a method for wood modification, and in particular, to a method for preparing a room temperature cured multifunctional wood modifier and a method for wood modification to solve the problems of high construction temperature, high toxicity, poor leaching-resistance and single function of existing wood modifiers. The method includes: step 1: weighing a hydrophobic polymer resin, an additive, a curing agent and a solvent, mixing and then stirring at room temperature to obtain a functional reagent A; step 2: weighing nanoparticles, a surface modifier and toluene, mixing and then stirring, cleaning with acetone, centrifuging, and drying to obtain a functional reagent B; step 3: adding a functional reagent C into the functional reagent A, evenly stirring, adding the functional reagent B, and performing ultrasonic processing to obtain the multifunctional wood modifier.

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 within 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.

The present disclosure is directed to a kit of parts comprising: in one part a) a water-borne stain; and, in another part b) a water-immiscible organic solvent-borne stain, wherein said water-borne stain is essentially free of resin and further contains at least one water-miscible organic solvent. The present disclosure is further directed to a method of coloring a wooden substrate comprising the steps of: a) applying a water-borne stain to a surface of the wooden substrate, wherein the water-borne stain is essentially free of resin and comprises at least one water-miscible organic solvent; and thereafter b) applying a water-immiscible organic solvent-borne stain to said surface.

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, system and network for prefabricating and constructing Class-A fire-protected wood-framed and mass timber buildings, while builders and owners are provided with knowledge of the quantity of carbon mass securely stored in Class-A fire-protected wood, represented by fire-protected carbon units (FPCUs), certified by the system and network. The network includes a system and mobile devices for estimating, recording and reporting the quantities of carbon mass securely stored in Class-A fire-protected wood-framed and mass-timber buildings on construction job-sites, and Class-A fire-protected wood-framed and mass timber components in factory environments, including engineered wood products (EWPs), mass timber assemblies and buildings constructed therefrom, whose quantized fire-protected carbon units (FPCUs) are also registered on the network for use in supporting various credits of value.

The present invention relates to a wood treatment device (1) for treating wood, and to a method for treating wood. Said wood treatment device (1) comprises a cylindrical hollow body (2) having inner end which is inside the wood when in use, and an outer end facing away from the inner end and at least one outlet opening (4). The cylindrical hollow body (2) comprises a receiving space (20′) which is designed to receive a carrier material (20) containing a wood treatment agent. Said wood treatment device (1) also comprises a thrust pin (10) which extends along the longitudinal axis of the cylindrical hollow body (2), and which can be moved outside of the cylindrical hollow body (2) on the outer end. Said thrust pin (10) comprises at least one closure section (11, 12) which closes at least one outlet opening when the wood treatment device (1) is not in use, and when the wood treatment device (1) is in use, the at least one outlet opening is released after moving and the receiving chamber is brought into contact with the wood.

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.

A method for preparing a treated cellulosic material comprising: providing a cellulosic material; a treatment protocol comprising impregnating the cellulosic material with an aqueous dispersion comprising a polybutene and a stabilizing agent.

The present invention relates to an improved method for impregnating a porous material, such as wood, more specifically a method in which an active ingredient to be deposited within the porous material is dissolved in condensed carbon dioxide and impregnated in the material.

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.
