The present disclosure relates to an adhesive comprising at least one of the following copolymer A: the copolymer A has at least one repeating unit carrying an amide group and a carboxyl and/or its ammonium salt and at least one other repeating unit different from the one carrying an amide group and a carboxyl and/or its ammonium salt. The present disclosure also relates to an artificial board formed of a lignocellulose material and the adhesive and a method for manufacturing the artificial board.

A method of forming a composite material includes: a) providing a substrate with fibres, lignin and hemicellulose; b) partially removing the lignin and hemicellulose from the substrate; and c) compressing the remaining substrate to form a compressed substrate. A composite material formed by the method is also provided.

Wood-based composites, compositions for use in wood-based composites, and associated systems and methods are provided herein. Certain compositions include a mixture of alpha olefins and esters and demonstrate unique water repellant properties. The compositions may be incorporated in wood-based composites in place of traditional petroleum-based slack waxes.

An adhesive for heat press molding contains a reaction product obtained by heat treatment on a mixture containing a polycarboxylic acid and a saccharide.

A method of forming an article is provided. Multi-fiber cellulose strips are interacted with a bonding agent and layered in a plurality of layers, the layered cellulose strips collectively defining opposed major surfaces. A porous sheet member, interacted with a fire-retarding solution, is engaged with one of the major surfaces of the layered cellulose strips, to substantially cover the major surface. The porous sheet member is disposed adjacent to a substantially smooth and uniform surface, and layered cellulose strips and the porous sheet member collectively exposed to an actuating element, configured to actuate the bonding agent to react in a volumetrically-expensive reaction with the fire-retarding solution to facilitate cohesion between the layered cellulose strips and the porous sheet member to form a board member, wherein the porous sheet member conforms to the adjacent surface via the volumetrically-expansive reaction to define a substantially smooth and uniform surface of the board member.

A membrane covered panel and a membrane covered panel production method are provided wherein an elastomeric membrane, and preferably, an aqueous elastomeric resin-based membrane, is applied to a finished panel construct, prior to pressing of the membrane covered panel. The method is used to produce panels which can be used in the production of flooring materials, wall panels, furniture, countertops, and the like. The membrane is applied to a transfer film, which transfer film can be removed at any time prior to, or after the pressing operation. The panels produced have a durable but elastic surface which can protect the surfaces of the panel construct. The elastomeric covering on the panel construct also preferably provides a surface which is abrasion resistant, and provides better acoustical properties while providing a soft touch haptic surface.

A method of forming an article and associated article are provided. Multi-fiber cellulose strips are interacted with a bonding agent and layered in a plurality of layers, the layered cellulose strips collectively defining opposed major surfaces. A porous sheet member, interacted with a fire-retarding solution, is engaged with at least one of the major surfaces of the layered cellulose strips, such that the porous sheet member substantially covers the at least one major surface. The layered cellulose strips and the porous sheet member are collectively exposed to an actuating element, configured to actuate the bonding agent to facilitate cohesion of the layered cellulose strips and the porous sheet member, to form a board member, wherein the at least one major surface cooperates with the porous sheet member engaged therewith, in response to the actuating element, such that the porous sheet member forms a substantially smooth and uniform surface.

A method of making a wood particle board containing sticking type resin coated wood particles wherein the top of a layup of the coated wood particles is smoothed to provide a smooth a top surface on the layup and a release agent is applied on the top surface and the so coated layup is consolidated into a board in a consolidating press under heat and pressure with the coated top surface in direct contact with a press platen.

A panel including a first layer including fragments from a first blend of paper fragments of a first size and plastic fragments of a second size, a second layer including fragments from a second blend of paper fragments of a third size and plastic fragments of a fourth size, the third size being different from the first size, and the fourth size being different from the second size, and a third layer comprising fragments from the first blend. The second layer is disposed between the first layer and the third layer.

A method for manufacturing a cellulose product, comprising the steps: dry forming a cellulose blank in a dry forming unit; arranging the cellulose blank in a forming mould; heating the cellulose blank to a forming temperature in the range of 100? C. to 200? C.; and pressing the cellulose blank in the forming mould with a forming pressure of at least 1 MPa.
