klebstoffmasse, druckformbare lignocellulosische composition, composite slab on the basis and method for the production lignocellulosischer verbundgegenstaende

摘要

An improved adhesive binder composition is provided for the preparation of lignocellulosic composite molded articles such as flake or particleboard, made from moldable compositions which comprises an organic di- or polyisocyanate and a cyclic alkylene ester of carbonic acid and optionally lignin, for application to the lignocellulosic material prior to the molding process to form the composite product.
