Abstract:
The present invention provides a new lumber adhesive, which comprises: 100 parts by weight water, 3~45 parts by weight proteinic raw material, 0.01~15 parts by weight acidity adjusting agent, 0.01~15 parts by weight aromatic compound, 0.01~15 parts by weight curing agent, 0.01~15 parts by weight antiseptic, 0.01~15 parts by weight viscosity regulator, 0~10 parts by weight filler and 0~15 parts by weight drier. The new lumber adhesive of the present invention can be used for adhesion of wood, veneer, flackboard, oriented strand boards (OSB), fibreboard, hard fibreboard, intermediate density board, high density board, cabinetwork board, man-made facing plate, floor substrate material and LVL. The present invention also provides the preparation of the new lumber adhesive.
Abstract:
The invention is directed to adhesives derived from animal or plant proteins, particularly canola and spent hen proteins. The adhesives are prepared by extracting the proteins by pH shifting; and either treating the extracted proteins with urea or sodium dodecyl sulfate, or polymerizing the proteins to form a protein-polymer conjugate. The invention is also directed to a wood based product comprising pieces of wood based material joined or consolidated with the adhesives.
Abstract:
A dried distiller soluble based biopolymer, processes for forming the biopolymer, and articles of manufacture thereof. The produced dried distillers solubles derives from co-products of corn fermentation facilities and is comprised in part of water-soluble proteins. A biopolymer consists essentially of dried distillers solubles, and an article of manufacture includes a biopolymer consisting of dried distillers solubles and an optional additive. The process of forming dried distiller solubles involves separating whole stillage into a liquid fraction and a solid fraction, wherein the liquid fraction comprises water soluble proteins in an amount greater than the solid fraction, and wherein the solid fraction has a higher solid content than the liquid fraction. The liquid fraction is sprayed at an elevated temperature to remove at least a portion of moisture in the liquid fraction and form particles and granules of the liquid fraction. Addition moisture is removed from the particles and granules in a fluidized bed to form dried distillers solubles, wherein the particles and granules are heated to a temperature less than 300F and have a residence time effective to reduce the moisture content of the dried distillers solubles to less than 20 percent to greater than 3 percent by weight.
Abstract:
A dried distiller soluble based bioadhesive composition and method for producing the dried distiller soluble based bioadhesives are disclosed, as well as derivatives thereof. The produced dried distillers solubles derives from co-products of corn fermentation facilities, and is advantageously comprised in part of water-soluble proteins. The method for producing the dried distillers solubles generally involves separation and/or introduction of targeted constituents and/or physiochemical treatment to facilitate use as an adhesive. Use of the method and bioadhesive compositions disclosed herein will improve the economics of fermentation by increasing co-product value, reducing plant-wide energy utilization, decreasing waste and emissions, and increasing overall product yield from each bushel of corn consumed.
Abstract:
An aqueous adhesive composition and a process for preparing such compositions are disclosed. The composition comprises macromolecular complex comprising (A) a first component comprising (i) a framework element and (ii) a polyphenol, and (B) second component comprising a polypeptide, oligopeptide, amino acid, or polyamine. The 5 framework element comprises (a) a polypeptide, oligopeptide, amino acid, or polyamine, (b) a polysaccharide, oligosaccharide, or monosaccharide, or a saccharide conjugate, or (c) a lignin, a lignan or a lignin conjugate. The polyphenol comprises a tannin, a tannic acid, a flavonoid, or a poly-resorcinol. An adhesive precursor composition comprising the first component is also disclosed.

Abstract:
Low temperature process and apparatus generally includes separating whole stillage into thin stillage and wet distillers grains, wherein the thin stillage comprises water soluble proteins in an amount greater than the wet distillers grains, and wherein the wet distillers grains has a higher solid content than the thin stillage; atomizing the thin stillage at an elevated temperature to remove at least a portion of moisture in the thin stillage and form particles and granules of the thin stillage; and removing additional moisture from the particles and granules in a fluidized bed to form dried distillers solubles. The apparatus includes an atomization section and a fluidized bed section configured to dry the thin stillage.
Abstract:
Polymer surfaces coated with organometallic layers, wherein the organometallic layers and polymer surfaces have functional groups that react to bond the organometallic layer to the polymer surface with organometallic functional groups remaining unreacted for the subsequent covalent attachment of organic overlayers. Coating methods and coated articles are also disclosed.
Abstract:
An improved secondary carpet backing fabric imparts increased resistance to buckling in carpets compared to conventional widely used secondary backings while providing the performance of conventional secondary carpet backings (e.g., similar peel strength, tuft bind, ease of handling). The improved backing is produced by a one-step weaving process and can be converted easily into carpet using current carpet making techniques. The inventive secondary carpet backing contains core-spun filling yarn with specific properties and is preferably woven in a leno or plain weave. Compared to carpets with conventional secondary backings, carpets with the inventive secondary backings display reduced growth in cyclic tensile testing.
