Description

Verfahren zur Herstellung von widerstandsfähigen und wasserdichten Gebrauchsgegenständen aus Hartpappe. Zusatz zum Patent 361229. Die Erfindung bezieht sich auf eine Abänderung des Verfahrens nach Patent 361229. Nach diesem sollen widerstandsfähige und wasserfeste Gegenstände aus Hartpappe derart hergestellt werden, daß man auf aus schwach gepreßter Zellulose geformte -Gegenstände Lacke aus Zelluloseestern, Zelluloseäthern oder anderen Zellulosederivaten aufbringt und die so getränkten Formen unter Druck und Hitze in Formpressen nachpreßt, worauf man die in dieser Weise vorbereiteten Gegenstände mit Lacken aus Zellulosederivaten überzieht und weiterhin gegebenenfalls heiß nachpreßt und poliert.Process for the production of resistant and waterproof articles of daily use from hard cardboard. Addition to patent 361229. The invention relates to a modification of the method according to patent 361229. According to this, resistant and water-resistant objects made of hard cardboard are to be manufactured in such a way that lacquers made of cellulose esters, cellulose ethers or other cellulose derivatives are applied to objects formed from weakly pressed cellulose and the so-soaked molds are re-pressed under pressure and heat in compression molding, whereupon the objects prepared in this way are coated with varnishes made from cellulose derivatives and, if necessary, re-pressed and polished with hot water.

Gemäß der Erfindung soll an Stelle der im Patent 36122g vorgesehenen ersten Tränkung der aus schwach gepreßter -Zellulose hergestellten Gegenstände mit Lacken aus Zellulosederivaten eine Tränkung mit anderen wasserfest machenden Mitteln treten. Als solche Mittel sind Lösungen der wasserunlöslichen harzsauren oder fettsauren Metallverbindungen oder alkoholische Lösungen von harzsaurem Magnesium, benzolische Lösungen von ölsaurem Blei oder Eisen, Lösungen von harzsaurem Chrom in Terpentinöl oder Ersatzmitteln zu verwenden.According to the invention, instead of that provided in patent 36122g first impregnation of the objects made from weakly pressed cellulose with Lacquers made from cellulose derivatives are impregnated with other waterproofing agents step. Such agents are solutions of the water-insoluble resin acids or fatty acids Metal compounds or alcoholic solutions of resinous magnesium, benzene Solutions of oleic lead or iron, solutions of resinous chromium in oil of turpentine or to use substitutes.
