The present invention relates to a process for preparing a bonding resin, wherein a resin prepared from lignin, phenol and formaldehyde is mixed with a resin prepared from phenol and formaldehyde to achieve a mixture useful as a bonding resin useful in the manufacture of laminates, mineral wool insulation and wood products such as plywood, laminated veneer lumber (LVL), medium density fiberboards (MDF) and particle boards.

A method of fabricating a cork composite material and a cork composite material. The method may comprise providing a plurality of cork particles in a volume and adding a dispersion of thermoplastic elastomer to the volume to provide a mixture of the dispersion of thermoplastic elastomer and the cork particles. The method may comprise agitating the cork particles and/or the mixture of the dispersion of thermoplastic elastomer and the cork particles and heating the mixture of the thermoplastic elastomer and the cork particles. The method may comprise allowing the mixture of the thermoplastic elastomer and the cork particles to cool. The steps of the method together may result in a plurality of coated cork particles being coated in a first layer of the thermoplastic elastomer.

A method for applying an adhesive resin in manufacturing an engineered wood product includes pre-heating an adhesive resin to a pre-application temperature before entry into an adhesive applier, maintaining the adhesive resin at the pre-application temperature for a controlled period of time to achieve improved pre-application chemical properties, and applying the adhesive resin on wood particles to form an engineered wood product.

A method for forming an engineered wood product includes grinding an MDI (methylene diphenyl di-isocyanate) binder together with water in a grinder to form a ground MDI dispersion. The ground MDI dispersion is fed into a wood production machine in which are lignocellulosic materials. The lignocellulosic materials are bound together by the ground MDI dispersion to form an engineered wood product.

A method of manufacturing a wood board, comprising: - applying a binder composition, notably in the form of an aqueous solution, to loose wood matter to provide resinated loose wood matter, wherein the binder composition consists of a binder composition prepared by combining reactants comprising at least 50% by dry weight reducing sugar reactant(s) and at least 5% by dry weight nitrogen-containing reactant(s); and—arranging the resinated wood matter as a sheet of loosely arranged resinated wood matter; and—subjecting the sheet of loosely arranged resinated wood matter to heat and pressure to cure the binder composition and to form the wood board from the sheet of loosely arranged resinated wood;—wherein the nitrogen-containing reactant(s) comprise TPTA triprimary triamine(s), notably wherein the nitrogen-containing reactant(s) comprise at least 5% by dry weight of TPTA triprimary triamine(s).

Binders, methods for making same, and methods for making composite lignocellulose products therefrom. The binder can include about 30 wt % to about 40 wt % of solids that include a urea-modified aldehyde-based resin; about 0.1 wt % to about 3 wt % of solids that include an isocyanate-based resin; about 0.1 wt % to about 12 wt % of an extender; and about 50 wt % to about 62 wt % of water, where all weight percent values are based on a total weight of the binder. The binder can have a sodium hydroxide equivalent weight alkalinity of about 3 wt % to about 9 wt %.

A non-carbohydrate polyhydroxy component(s) is used in a binder composition to facilitate manufacture of wood particle boards.

Provided are a structure and a method of forming a structure that includes a core made, at least in part, of a rice hull composition. The rice hull composition including a combination of separate, unground rice hulls; ground rice hulls; and a rice hull powder, that each have a different particle size. A polymeric binder, such as a recycled plastic polymeric binder binds the separated unground rice hulls, the ground rice hulls and the rice hull powder together.
