A composite material is formed by preparing mass particles consisting of a fibrous material at least partially derived from recycled post-consumer materials and preparing particles of a binding material consisting of a thermoplastic material at least partially derived from recycled post-consumer material. The prepared mass particles and particles of binding material are mixed together such that the binding material liquifies and coats the mass particles which are subsequently then pressed together to form a composite article in which the mass particles typically occupy between 35% and 60% by weight of the composite material and the binding material occupies between 40% and 60% by weight of the composite material. The composite material is suitable for replacing concrete, wood, or other construction, manufacturing or industrial materials, and possesses properties that in some applications may be equal or superior such materials.

The invention relates to a process for producing a thermoformable and/or embossable particle/polymer composite using a substrate S based on shredded polymer-coated paper and a thermoplastic polymer P, therewith providing a new method of recycling/upcycling paper waste. Furthermore, a process for the manufacturing of a molded article obtained from the paper-based particle/polymer composite and its use as an element in buildings or in furniture are disclosed.

A thermally fused board manufacturing apparatus includes: a fiberizing section that produces a fiber material by fiberizing a raw material containing fabric; a material supply pipe section that carries the fiber material; a humidifying section configured to humidify the fiber material; a carriage pipe section that adds a material different from the fiber material to the fiber material and carries the material and the fiber material; a mixing section that produces a deposition fiber material by mixing the material and the fiber material, at part of the carriage pipe section; a depositing section that forms a fiber aggregate by depositing the deposition fiber material; a thermal fusing section that forms a thermally fused board by applying heat and pressure to the fiber aggregate; and a controller that controls the humidifying section.

Described is a method for manufacturing a composite panel. The method broadly includes the steps of introducing a composite mixture into a press or mould, the composite mixture comprising about 4% to about 30% by weight of a binder that comprises a particularised plastic having a particle size of less than 4 mm, and the remainder being provided by a substrate. The composite mixture is then subjected to pressure sufficient to decrease the thickness of the composite mixture and is heated to about 100? ? C. to about 220? ? C. to form the wood composite panel.

The invention is directed to a process for the manufacture of composite wood structures, which provides for increased production rates and machinability. More particularly, the process comprises combining wood particles with a composition comprising an aqueous protein and diluent dispersion.

The disclosure relates to adhesive compositions, including non-crosslinked resins and crosslinked/cured adhesives joining substrates, as well as related methods for making the compositions and articles. Compared to a conventional phenol (P) and formaldehyde (F) resin, the disclosed methods and compositions use lignin (L), formaldehyde (F), and optionally higher aldehydes (A) as corresponding replacements to provide an analog to a conventional PF resin with biobased reactants. Due to the differing reactivity of the LF components compared to the PF components, the initial condensation reaction between ortho-reactive sites in the lignin and the aldehyde is controlled to prevent gelation of the aqueous reaction mixture while reacting substantially all of the LF reactants to provide a non-crosslinked resin reaction product. The resin reaction product can then be cured at high temperature/high pressure conditions to provide a crosslinked adhesive, for example joining two substrates.

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.

The present application relates to wood boards, particularly post-cured wood boards and more particularly to particle board with excellent swelling properties; it also relates to a process for production of such boards.

Disclosed is an aqueous bonding composition comprising: (A) a saccharide; (B) a water-soluble synthetic resin; and (C) an inorganic acid ammonium salt, wherein the inorganic acid ammonium salt (C) comprises at least one selected from ammonium dihydrogen phosphate and ammonium chloride. The water-soluble synthetic resin (B) preferably comprises a polyvinyl alcohol-based compound. A wood-based material obtainable by using the aqueous bonding composition is also disclosed.

The aqueous bonding composition is useful for improving performances such as bending strength, bending strength under wet condition, water-absorption thickness expansion coefficient, and peeling strength of a wood-based material in a balanced manner while the composition is capable of bonding at a comparatively low temperature and each component of the composition is excellent in compatibility.

Described is a process of producing a multi-layer lignocellulosic composite comprising one or more lignocellulosic composite layers or a single-layer lignocellulosic composite, wherein a high-frequency electrical field is applied and wherein a binder comprising for hardening the binder via esterification at least one, two or more compounds having two or more hydroxy groups and additionally one, two or more compounds having two or more carboxyl groups is provided or prepared. Furthermore described is a lignocellulosic composite, which is preparable according to that process, a construction product comprising such lignocellulosic composite, the use of such lignocellulosic composite as a building element in a construction product and a binder or binder composition for producing a lignocellulosic composite.
