Verfahren zum Papierverflüssigen, Verflüssigte Papierzusammensetzung und Verfahren zur Herstellung eines Kunststofformteils mit dieser Papierzusammensetzung

摘要

Disclosed is a method of liquefying a paper material, a liquefied paper composition and a method of manufacturing a plastic molding from a paper material by using the liquefied paper composition. The paper is shear broken into small pieces and mixed with a liquefying agent containing: an alkaline catalyst or an acidic catalyst; and at least one liquid compound which is selected from the group consisting of hydroxyphenyl compound, polyol and cyclic ester. The mixture is heated to obtaining a liquefied paper composition. Isocyanate compound or a curing agent for phenol resins is added to the liquefied paper composition and the mixture is molded to form the plastic molding, which is usable in place of conventional plastic articles.
