  • Formaldehyde-free adhesives and lignocellulosic composites made from the adhesives
    Patent number: 7722712
    Abstract: A first variant of an adhesive composition for making a lignocellulosic composite includes soy protein and/or lignin; at least one substantially formaldehyde-free curing agent that includes at least one amine, amide, imine, imide, or nitrogen-containing heterocyclic functional group that can react with at least one functional group of the soy protein; and at least one compound selected from a boron compound, a group IA oxide or hydroxide, or a group IIA oxide or hydroxide. A second variant of an adhesive composition includes a first component selected from soy protein and/or lignin; and at least one substantially formaldehyde-free curing agent selected from a reaction product of epichlorohydrin with ethylenediamine, a reaction product of epichlorohydrin with bis-hexamethylenetriamine, or a reaction product of epichlorohydrin with hexamethylenediamine.

  • Silanization of Wood Turnings and Fibers for Producing Wood-Plastic Composite Materials
    Publication number: 20090007818
    Abstract: The present invention relates to composite materials composed of lignocellulosic fibers, for example wood meal, and thermoplastic polymer. The inventive composite material has improved mechanical properties. According to the invention, it is envisaged that the lignocellulosic fibers, before mixing with the thermoplastic polymer, are treated with an aqueous mixture composed of organopolysiloxanes which contain aminoalkylalkoxysilanes.
