Patentiert im Deutschen Reiche vom 15. Mai 1908 ab.Patented in the German Empire on May 15, 1908.
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von haltbarer Dachpappe oder Dachfilz. Das Verfahren besteht darin, daß die Pappe oder der. Filz vor der Ölimprägnierung mit Cuprisulfat oder Ferrosulfat oder einem ähnlichen in der Holzimprägnierungstechnik benutzten Salz behandelt wird.The present invention relates to a method of making durable roofing felt or roof felt. The procedure is that the cardboard or the. Felt in front of the Oil impregnation with cupric sulfate or ferrous sulfate or a similar in the wood impregnation technique used salt is treated.
Es ist bekannt, den zur Imprägnierung von ίο Pappe dienenden Teerölen o. dgl. Imprägnierungssalze, wie Eisenvitriol, wasserlösliche Kupfersalze usw., hinzuzusetzen. In dieser Form vermögen aber die Salze nicht so in das Innere der Pappe einzudringen, wie dies nach dem vorliegenden Verfahren geschieht. Infolgedessen ist der Imprägnierungseffekt nach dem vorliegenden Verfahren ein besserer.It is known that the tar oils or the like impregnation salts used for the impregnation of cardboard, such as iron vitriol, water-soluble copper salts, etc., to be added. In this form, however, the salts are not so capable penetrate the inside of the paperboard, as is done according to the present method. As a result, according to the present method, the impregnation effect is better.
Das Verfahren kann z. B. in folgender Art und Weise zur Ausführung gebracht werden:The method can e.g. B. be carried out in the following way:
Rohe Pappe beliebiger Art oder Filz wird mit einer Cuprisulfat- oder Ferrosulfatlösung (5 bis 2oprozentig) o. dgl. imprägniert. Darauf wird das Material zwischen Walzen gepreßt und eventuell getrocknet; dann wird es in ein Bad aus Kohlenteer oder Teerölen oder anderen geeigneten ölen übergeführt, und schließlich passiert die Pappe oder der Filz wiederum einen Satz Walzen, worauf das Material zum Gebrauch fertig ist.Raw cardboard of any kind or felt is made with a cupric sulfate or ferrous sulfate solution (5 to 2 percent) or the like. Impregnated. The material is then pressed between rollers and possibly dried; then it is put in a bath of coal tar or tar oils or transferred to other suitable oils, and finally the cardboard or felt passes through again a set of rollers, whereupon the material is ready for use.
