Description

Verfahren zum Leimen von Papier. Den Gegenstand der Erfindung bildet ein Verfahren zum Leimen von Papier unter Verwendung von Montanwachsemulsionen, insbesondere von solchen Emulsionen, die ganz oder im wesentlichen Teil aus Rohmontanwachs bestehen.Method for gluing paper. Forms the subject of the invention a method for sizing paper using montan wax emulsions, in particular of those emulsions which are wholly or essentially made from raw montan wax exist.

Rohmontanwachs, das unmittelbar durch Extraktion aus der Rohkohle gewonnen wird, verhält sich in bezug auf Emulgierbarkeit insofern vollkommen anders als das raffinierte Montanwachs, als das Rohmontanwachs der Emulgierung den größten Widerstand entgegensetzt. Andererseits aber und gerade im Zusammenhang mit diesem Verhalten dürfte die Tatsache stehen, daß das Rohmontanwachs für die Papierleimung ungleich wertvoller ist als das raffinierte Montanwachs, was darin seinen Ausdruck findet, daß man mit wesentlich geringeren Mengen Rohmontanwachs mindestens eine ebenso gute Leimung erzielt wie mit raffiniertem Montanwachs.Raw montan wax obtained directly by extraction from the raw coal is obtained, behaves completely different in terms of emulsifiability as the refined montan wax, as the raw montan wax of emulsification the greatest Opposes resistance. On the other hand, and especially in connection with this The fact that the raw montan wax is used for paper sizing is likely to stand is incomparably more valuable than the refined montan wax what it expresses finds that with much smaller amounts of raw montan wax, at least one just as good gluing achieved as with refined montan wax.

Die Herstellung des Leimungsmittels und seine Verwendung kann z. B. wie folgt geschehen: Ein Druckkessel wird mit 6oo kg Rohmontanwachs und 45 bis Zoo kg Ätzalkalilösung von 36° B6 beschickt. Nach Einlauf von etwa 2 ooo 1 wird der Kessel geschlossen und bei 5 bis 7 Atm. Druck durch 5 bis =o Stunden " erhitzt, bis eine Probe in Wasser gleichmäßig emulgiert. Löst man 4oo kg dieses Produktes heiß in 6oo 1 Wasser, dann erhält man eine Leimmilch, von welcher 2o bis 3o1 auf ioo kg Papierstoff im Holländer zugesetzt genügen, um nach vollzogener Fällung mit Tonerdesulfat oder dessen Ersatzmittel, z. B. Bisulfat, verdünnter Schwefelsäure usw., dem fertigen Papier vollkommene Tintenfestigkeit zu verleihen. Verwendet man höhere Zusätze, z. B. 6o 1 obiger Leimmilch, so erzielt man Wasserfestigkeiten, die einer Imprägnierung in bezug auf den Effekt nahekommen.The preparation of the sizing agent and its use can e.g. B. done as follows: A pressure vessel is filled with 600 kg of raw montan wax and 45 to zoo kg caustic alkali solution of 36 ° B6 charged. After running in about 2,000 1, the Kettle closed and at 5 to 7 atm. Pressure heated by 5 to = o hours, until a sample emulsifies evenly in water. Dissolve 400 kg of this product hot in 600 liters of water, then you get a glue milk, of which 2o to 3o1 on 100 kg of paper stock added in the Hollander is enough to continue with after the precipitation has been completed Alumina sulfate or its substitute, e.g. B. bisulfate, dilute sulfuric acid etc., to give the finished paper perfect ink resistance. If you use higher additives, e.g. B. 6o 1 above glue milk, then one achieves water resistance, that come close to impregnation in terms of the effect.

Die mit Rohmontanwachs allein hergestellten Papierleime sind nach den in der Praxis gemachten Erfahrungen geeignet, Leime aus Harz (Kolophonium) hinsichtlich der Leimwirkung zur Herstellung leimfester (schreibfester) Papiere vollkommen zu ersetzen. Daß Rohmontanwachs gegenüber dem Montanwachs (Destillat bzw. Raffinat) eine so überraschende Leimwirkung hat, dürfte darauf zurückzuführen sein, daß in dem Rohmontanwachs außer den wachsartigen Anteilen noch größere Mengen Substanzen vielleicht harzartiger Natur enthalten sind, die die Papierleimung günstig beeinflussen und die bei der Raffination und Destillation wahrscheinlich zerstört werden. _The paper sizes made with raw montan wax alone are after Based on the experience made in practice, glue made of resin (rosin) is suitable with regard to the glue effect for the production of glue-resistant (write-resistant) papers completely substitute. That raw montan wax compared to montan wax (distillate or raffinate) has such a surprising glue effect is probably due to the fact that in In addition to the waxy components, the raw montan wax contains larger amounts of substances Perhaps of a resinous nature are contained, which have a beneficial effect on paper sizing and which are likely to be destroyed in refining and distillation. _
