Description
Verfahren zur Herstellung von Dacheindeckungsmaterial für Eisenbahnfahrzeuge o. dgl. Die Erfindung bezieht sich auf die Herstellung von Dacheindeckungsmaterial für Eisenbahnfahrzeuge o. dgl., also für Fälle, wo das Material besonderen Beanspruchungen, wie Verschiebungen und Werfen usw., ausgesetzt ist.Process for the production of roofing material for railway vehicles The invention relates to the manufacture of roofing material for railway vehicles or the like, i.e. for cases where the material is subject to special stresses, such as displacements and throws, etc., is exposed.
Die Erfindung betrifft nun ein Eindekkungsmaterial, welches aus zwei oder mehr Schichten besteht, die abwechselnd aus einem Gewebe hergestellt sind und abwechselnd aus einer Masse, die in der Hauptsache Nitrocellulose enthält. Diese Nitrocellulosemasse enthält außer Trikresylphosphat noch Füll-und Farbstoffe.The invention now relates to a covering material, which consists of two or more layers made alternately of a fabric and alternately from a mass that mainly contains nitrocellulose. These In addition to tricresyl phosphate, nitrocellulose mass also contains fillers and colorants.
Ein Beispiel für die Zusammensetzung solcher Nitrocellulose ist etwa: 2o bis 25 Teile Nitrocellulo.se, 3o bis q.o Teile Trikresylphosphat und 15 bis 25 Teile Lithopone, ferner Füllmittel, wie Gips, Kreide, Talkum und Farbstoffe, je nach Wahl und dem jeweiligen Verwendungszweck. Die Gewebeschichten werden unter Druck in der Wärme mittels der bekannten Masse aus Nitrocellulose, Trikresylphosphat und Beschwerungsmitteln fest vereinigt, worauf auf die beiden Außenseiten ebenfalls unter Druck und in der Wärme dieselbe Masse aufgewalzt wird.An example of the composition of such nitrocellulose is about: 2o to 25 parts of nitrocellulose, 3o to q.o parts of tricresyl phosphate and 15 to 25 Parts of lithopone, also fillers such as plaster of paris, chalk, talc and dyes, each of your choice and the respective purpose. The layers of tissue are underneath Heat pressure by means of the well-known mass of nitrocellulose, tricresyl phosphate and weighting means firmly united, whereupon also on the two outer sides the same mass is rolled under pressure and with heat.
Ein vorteilhaftes Material ergibt sich also bei folgender Zusammensetzung im Querschnitt Eine Unterschicht aus Nitrocellulosemasse, in gleicher oder ähnlicher Zusammensetzung wie hoben angegeben, darüber eine Gewebebahn, alsdann eine weitere Nitrocelluiosemasseschicht aus solcher Nitrocellulose, dann wieder eine Gewebebahn und abschließend nach oben eine letzte Schicht aus solcher Nitrocellulos;emasse. Die Zusammensetzung und Verbindung der einzelnen Schichten erfolgt lediglich unter Druck und Wärme ohne Verwendung besonderer Klebemittel.An advantageous material is thus obtained with the following composition in cross-section a sub-layer of nitrocellulose mass, in the same or similar Composition as stated above, over it a web of fabric, then another Nitrocellulose compound layer made of such nitrocellulose, then again a web of fabric and finally upwards a last layer of such nitrocellulose; emasse. The composition and connection of the individual layers takes place only below Pressure and heat without the use of special adhesives.
Das auf diese Weise hergestellte Dacheindeckungsmaterial besitzt gegenüber dem bisherigen den Vorteil, daß es infolge besonders großer Dehnbarkeit allen Verschiebungen der Bedachung folgen kann, ohne in seiner Wasserdichtigkeit irgendwie Schaden zu leiden. Insbesondere zeigt es die neue technische Wirkung, daß nach Verletzung der oberen Belagschicht, z. B. beim Begehen der Dächer, sich immer noch eine zweite Schicht zwischen den beiden Gewebebahnen befindet, die in diesen Fällen ein Undichtwerden gegen Wasserfeuchtigkeit nicht zuläßt.The roofing material produced in this way has opposite the previous one the advantage that it is due to particularly great extensibility all displacements can follow the roofing without causing any damage to its waterproofness To suffer. In particular, it shows the new technical effect that after violation of the upper layer of pavement, e.g. B. when walking on the roofs, you still get a second Layer is located between the two webs of fabric, which in these cases will leak against water moisture.
Insbesondere besitzt die Doppelbahn auch auf der Rückseite einen Massebelag, der sie gegen etwa aus dem Innern der Wagen dringende Feuchtigkeit schützt. Trotzdem kann das lehr elastische Material allen Krümmungen des Daches folgen und ohne Einschnitte über die Dachkanten und -ecken gezogen= werden.In particular, the double track also has a ground coating on the back, which protects them against moisture penetrating from inside the car. Nevertheless the elastic material can follow all the curvatures of the roof and without incisions over the roof edges and corners = be drawn.
Gegenüber dem amerikanischen Patent io6568q. fällt die Verwendung leichtflüchtiger Lösemittel fort und tritt an deren Stelle das nichtflüchtige, schwer brennbare Trikresylphosphat, wodurch die Brennbarkeit des Dachbelages wesentlich herabgesetzt wird. Auch beim bekannten Patent 3q.0279 werden flüchtige Lösemittel und Naphthensäureester verwendet, die das Endprodukt nicht wie das Trikresylphosphat schwer verbrennlichmachen. Auch sind cellulöidartigeMassen wegen der leichten Brennbarkeit für Dachbelag ungeeignet.Compared to the American patent io6568q. falls the use volatile solvent continues and replaces it with the non-volatile, difficult one flammable tricresyl phosphate, which makes the roof covering more flammable is reduced. The known patent 3q.0279 also uses volatile solvents and naphthenic acid esters used that the final product doesn't like make the tricresyl phosphate difficult to burn. Also are celluloid-like masses unsuitable for roofing due to its easy flammability.
