Abstract

Die Erfindung betrifft ein Verfahren zur Eigenschafts­ verbesserung, insbesondere der Wasserbeständigkeit und mechanischen Festigkeit, von aus cellulosehaltiger Faser­ stoff-Aufschlämmung durch Pressen erzeugten Formteilen. Erfindungsgemäß werden die Faserstoff-Formteile einem Unterdruck ausgesetzt, dann mit einem geeigneten fließ­ fähigen Isocyanat in Kontakt gebracht (benetzt), gegebe­ nenfalls nach Entfernen überflüssigen Harzes von der Ober­ fläche der Formteile einer Druckerhöhung unterworfen und anschließend ausgehärtet. The invention relates to a method for properties improvement, especially water resistance and mechanical strength, from cellulosic fiber fabric slurry molded parts produced by pressing. According to the fibrous molded parts are one Exposed to vacuum, then with a suitable flow capable isocyanate brought into contact (wetted), given after removing unnecessary resin from the upper surface of the molded parts subjected to a pressure increase and then cured.
