METHOD FOR THE PREPARATION OF LIGNOCELLULOSIC COMPOSITE ARTICLES BY USING AN ORGANIC POLYISOCYANATE OR ALKYLENE OXIDE ADHESIVE COMPOSITION

摘要

An improved adhesive binder composition is provided for the preparation of lignocellulosic composite molded articles, especially flake or particleboard, made from moldable compositions which comprises an organic polyisocyanate-alkylene oxide or halogenated alkylene oxide and optionally lignin, for application to the lignocellulosic material prior to the molding process to form the composite product.
