Description

Verfahren zur Herstellung einer wasserdichten Pappe. Die Erfindung betrifft ein Verfahren zur Herstellung einer Art Pappe, die sich als Wandbekleidung, Fußbodenbelag, Stoff zui Schuhsohlen, insbesondere Zwischensohlen, Kappen, Zwischenflecken für Absätze und ähnliche Zwecke verwenden läßt.Method of making a waterproof cardboard. The invention relates to a process for the production of a type of cardboard that can be used as wallcovering, Floor covering, fabric for shoe soles, in particular midsoles, caps, intermediate patches can be used for paragraphs and similar purposes.

Das neue Verfahren, wird folgendermaßen ausgeführt: Harte, imprägnierte Spinnpapiergewebeabfälle werden in einem scharfen Kollergang gemahlen und so in rohe Fasern zerlegt. Im Kollergang werden auf ioo kg Fertigfabrikat io kg Asphalt-Fagat (wasserlösliches Bitumen zum Leimen, Wasserfest-und Wasserdichtmachen von Papierstoff der chemischen Fabrik von Dr. Nördlinger in Flörsheirn), io kg Teerleim (einer mittels Natronlauge und Formaldehyd. hergestellten Teerseife) und' io kg Preolit (eine wasserfeste, teerähnliche, gereinigte Anstrichmasse) zugefügt.. Die Masse wird darauf im Holländer nachgemahlen und noch im Holländer mit 15 kg einer i6proz. wäßrigen Auflösung von schwefelsaurer Tonerde versetzt, welche die genannten Zusätze auf der Faser niederschlägt.The new process is carried out as follows: Hard, impregnated spinning paper fabric waste is ground in a sharp pan mill and thus broken down into raw fibers. In the pan mill, 10 kg of asphalt fagate (water-soluble bitumen for gluing, waterproofing and waterproofing of paper from the chemical factory of Dr. Nördlinger in Flörsheirn), 10 kg of tar glue (a tar soap made with caustic soda and formaldehyde) and ' 10 kg of Preolit (a waterproof, tar-like, cleaned paint) added. The mass is then re-ground in the Hollander and still in the Hollander with 1 5 kg of an i6proz. aqueous solution of sulfuric alumina added, which precipitates the additives mentioned on the fiber.

' Die so erhaltene Masse läßt man auf die= Pappenmaschine auflaufen und bringt sie in üblicher Weise in Form von Tafeln. Die so erhaltenen Papptafeln werden in einem Trockenkanal mit heißer Luft (bei warmem `Vetter zuerst an der Luft, dann im Kanal) getrocknet, darauf gepreßt und endlich auf einem Glättwerk unter Hochdruck geglättet und gewalzt.The mass obtained in this way is allowed to run on the cardboard machine and brings them in the usual way in the form of tablets. The cardboard panels thus obtained are in a drying tunnel with hot air (with a warm cousin first in the air, then in the canal) dried, pressed on and finally on a smoothing under High pressure smoothed and rolled.

Die Papptafeln kann man nachträglich noch längere Zeit in heißen Preolit tauchen, zwischen mit Filz bekleideten Walzen von dem Überschuß des Preolits befreien, im Trockenkanal trocknen und schließlich nochmals unter Hochdruck im Glättkalander oder Glättwerk glätten.The cardboard panels can be subsequently used in hot Preolit for a longer period of time immerse, free from the excess of the preolite between rollers lined with felt, Dry in the drying tunnel and finally again under high pressure in the smoothing calender or smoothing the smoothing unit.
