Most processes currently being proposed and/or used for the production of lignin from kraft or soda black liquors are capable of producing two main types of lignin: high residual content (HRC) lignin and low residual content (LRC) lignin. Surprisingly, it was discovered that HRC lignin, is a suitable ingredient in alkaline adhesives, particularly wood adhesives of the phenolic type (e.g. resole resins). This biomaterial is environmentally green and remarkably low cost, which makes it an industrially viable material to be used as a novel and major ingredient in phenolic adhesives for the manufacture of exterior grade plywood, laminated veneer lumber, oriented strand board (OSB) and other wood products&#x2014;this was successfully demonstrated in a number of laboratory experiments as well as several different mill trials. The composition, preparation and application of such wood adhesives are hereby disclosed.

High residual content (HRC) kraft/soda lignin as an ingredient in wood adhesives

The application describes a method of scavenging formaldehyde from a wooden composite comprising urea-formaldehyde or melamine urea-formaldehyde by providing a combination of formaldehyde scavengers in the face and core layers of the composite and further describes the composite produced with these scavengers.

A method of producing ultra-low density fiber composite (ULDC) foam materials using natural fibers with gas injection through liquid foaming is disclosed, wherein in a particular embodiment includes also cellulose filaments. The method includes a continuous overflow foaming process and a novel apparatus to produce the ULDC materials. The disclosed ULDC composite foam produced includes moisture, mold, decay and fire resistant properties which can be used for building thermal and acoustic insulations, protection packaging, air filter products, hygiene products. The apparatus comprise a vessel, counter rotating dual impellor, a plurality of baffles and gas injection that produce.

Method of producing ultra-low density fiber composite materials

Disclosed herein are method to modify the lignin with particular fungal species, and procedure to synthesize phenolic adhesives with the modified lignin as raw materials, and the adhesives compositions and methods for making adhesive compositions, and methods for making lingo-cellulosic composites from renewable materials. Four fungi in examples are(Spreng.) Pat. (FTK 329A),(Bres.) Parmasto (FTK 332A),(Ellis & Everh.) Kotl. & Pouz. (FTK 76A) and(Pers.) Bondartsev (FTK 122B). Lignin used in examples are organosolv lignin, Kraft lignin, and ammonium lignosulfonate. The present invention includes methods to (1) modify of lignin with fungi; (2) in-situ polymerize modified lignin-phenol-formaldehyde to generate bio-modified lignin-phenol-formaldehyde adhesive in liquid form, and (3) manufacture composite panels with bio-modified lignin-phenol-formaldehyde resins.

Process for fungal modification of lignin and preparing wood adhesives with the modified lignin and wood composites made from such adhesives

The present invention provides methods to functionalize and solubilize WCNT with a phenolic polymer such as a lignin or a PF resin followed by in-situ integration of this functionalized CNT in the presence of formaldehyde and phenol and/or lignin to generate either CNT-reinforced phenol-formaldehyde polymer or CNT-reinforced lignin-phenol-formaldehyde polymer in either liquid or powder form suitable as an adhesive in the manufacture of a lignocellulosic composite material such as OSB and plywood.

The present invention describes a fungal modified chitosan adhesive for binding a fibrous material and the method of producing the adhesive. The adhesive is produced by providing a chitosan containing raw material; a fungal growing medium; a fungal culture; mixing the raw material, the growing medium and the fungal culture together to produce a suspension; incubating the suspension to produce a broth comprising a modified chitosan solid, an at least partially-consumed medium liquid and a fungal residue; separating the modified chitosan solid from the liquid and the fungal residue, and dissolving the modified chitosan solid to produce the adhesive resin.
