Compressed articles and methods of manufacturing the same
A compressed article formed by a composite material comprising a thermoset polymer and a wood material, a method of producing the same and the use of the novel articles. The composite material has a continuous matrix of a hardened thermoset polymer and, distributed within the matrix, wood chips which are at least partially encased by the thermoset polymer, said article having a water absorbency of less than 1% by weight upon immersion into water over a time period of at least 168 h at room temperature. The articles can be used in structures that are frequently contacted with water.
PROCESS FOR PREPARING A BONDING RESIN
The present invention relates to a process for preparing a bonding resin, lignin in solid form or in the form of a dispersion in water is mixed with a crosslinker; and optionally one or more additives followed by addition of a basic solution. The bonding resin is useful for example in the manufacture of laminates, mineral wool insulation and wood products such as plywood, oriented strandboard (OSB), laminated veneer lumber (LVL), medium density fiberboards (MDF), high density fiberboards (HDF), parquet flooring, curved plywood, veneered particleboards, veneered MDF or particle boards, laminates or mineral wool insulation.
POLYMERIC MATRIX PLYWOOD
Polymeric Matrix Plywood (PMP) is the technical knowledge of manufacturing and using polyolefin resin(One part), for making primers, adhesives and paints, with a process at room temperature And applied in wood and plastic industries and pre-processing of thin wood veneers and plywood construction with Making it possible to glue wooden and plastic layers together and effective penetration of primer and polyolefin adhesive to both wood and thermoplastics materials surfaces, With high penetration and saturation of wood textures and vessels, for making recyclable and renewable polyolefin adhesives and paints for wood, with the possibility of adding electrical conductivity to polyolefin resin And obtaining anti-electrostatic properties of the resulting surfaces, and creating the necessary conditions for plating wooden or plastic surfaces, [FIG. 2].

AMINO RESIN PERFORMANCE WITH SULFONATED LIGNIN
A resin system and methods of making resin system wherein lignosulfonate is added to urea-formaldehyde and melamine-urea-formaldehyde adhesives. Lignosulfonate is added to the resins which improves the performance characteristics of the adhesive while reducing environmental impact by consuming byproducts from other industrial processes. The resin system includes a urea-formaldehyde (UF) resin or melamine-urea-formaldehyde (MUF), prepared in at least two stages wherein the UF resin or MUF resin has a molar ratio (MR) of total moles formaldehyde to total moles urea plus, if present, the one or more melamine compounds of from about 0.25:1 to about 2.50:1, and wherein one or more lignosulfonate compounds are included in an amount of from about 0.1-30 wt. %, based on a total weight of the resin system, and wherein the resin system has a buffer capacity of 2-400 mL of 0.1 N HCl by the ATV Method for a period of time of at least about 20 days at 25° C.
