Bekanntlich müssen die für die Herstellung der verschiedenen Papiere verwendeten Cellulosefasern nach den Vorgängen des Kochens, Bleichens, Reinigens usw. mit Chemikalien versetzt werden, die ihre Wasserfestigkeit erhöhen sollen.It is known that the cellulose fibers used for the production of the various papers must chemicals are added after cooking, bleaching, cleaning, etc. to increase their water resistance.

Das hierfür üblichste Mittel ist das Natriumresinat, das durch Aluminiumsulfat als Aluminiumresinat auf der Faser niedergeschlagen wird.The most common means for this is sodium resinate, which is replaced by aluminum sulfate as aluminum resinate is deposited on the fiber.

Es wurde nun gefunden, daß man besonders wertvolle und den bisherigen Verfahren überlegene Ergebnisse hinsichtlich der Wasserfestigkeit und der Oberflächenbeschaffenheit des Papiers erzielen kann. Erfindungsgemäß wird dabei an Stelle des Natriumresinats eine Harzemulsion verwendet, die außerdem noch Paraffin und Zusatzstoffe, wie Netzmittel für die Erleichterung des Eindringens und fungizide Mittel, zur Verhinderung der Schimmelbildung enthält.It has now been found that they are particularly valuable and superior to the previous processes Achieve results in terms of water resistance and surface quality of the paper can. According to the invention, instead of the sodium resinate, a resin emulsion is used which also paraffin and additives such as wetting agents to facilitate penetration and contains fungicides to prevent mold growth.

Nachstehend ist zur näheren Erläuterung ein Ausführungsbeispiel für das Verfahren gegeben.An exemplary embodiment of the method is given below for a more detailed explanation.

Man vermischt in einem Kollergang bei einer Temperatur von 6o bis 8o°:Mix in a pan at a temperature of 6o to 8o °:

Harzseife (zu 25% aus Natriumresinat) 5 bis 25 kg Alkylarylsulfosaures Natrium . . . 1 bis 10 kgResin soap (25% from sodium resinate) 5 to 25 kg of alkylarylsulfonate sodium. . . 1 to 10 kg

Gelatine 20 bis 5 kgGelatin 20 to 5 kg

Paraffin 40 bis 5 kgParaffin 40 to 5 kg

Pentachlornatriumphenolat . . . . 1 bis 2 % Wasser bis auf 100 kg auffüllen.Pentachloro sodium phenolate. . . . 1 to 2 % Fill up with water up to 100 kg.

Die Harzseife kann ganz oder teilweise durch andere Erzeugnisse ersetzt werden, die ebenfalls unlösliche Aluminiumsalze ergeben, z. B. durch Seifen von Fettsäuren, Alkalisalze der Carboxymethyl-The resin soap can be replaced in whole or in part by other products that also result in insoluble aluminum salts, e.g. B. by soaps of fatty acids, alkali salts of the carboxymethyl

cellulose, Alginate usw. Auch Harnstoff kann zugesetzt werden.cellulose, alginates, etc. Urea can also be added.

Die Emulsion ist völlig beständig und kann in jedem Verhältnis mit Wasser ohne Rücksicht auf dessen Härte oder pH-Wert verdünnt werden.The emulsion is completely permanent and can be used in any proportion with water regardless of whose hardness or pH value are diluted.

Die so hergestellte Emulsion wird wie folgt angewandt: Sie wird in einer solchen Menge in einen Holländers gebracht, daß 0,5 bis io°/o Paraffin auf trockenen Zellstoff verwendet werden.The emulsion thus prepared is applied as follows: it is in such an amount in a Holländers said that 0.5 to 10 per cent of paraffin was used on dry pulp.

Der Zusatz eines Netzmittels zur Emulsion begünstigt nicht nur die Emulgierung, sondern führt auch zu einer beträchtlichen Verbesserung der Verteilung der Emulsion auf der Cellulosefaser und sogar des Eindringens derselben in die Cellulosefaser, was im Hinblick auf die gewünschte Wirkung von großer Bedeutung ist.The addition of a wetting agent to the emulsion not only favors emulsification, it also leads to it also to a considerable improvement in the distribution of the emulsion on the cellulose fiber and even the penetration of the same into the cellulose fiber, which in view of the desired effect is of great importance.

Sowie das Cellulose-Emulsionsgemisch eine gute Homogenität aufweist, wird zur Fällung als AIuminiumresinat Aluminiumsulfat zugesetzt. Man muß am Schluß bei einem ρκ-Wert von 4,5 arbeiten. Ist das Gemisch richtig homogen geworden, so läuft es durch die Papiermaschine, ohne daß hierdurch das Verfahren der Papierherstellung eine Änderung erführe.As soon as the cellulose-emulsion mixture has a good homogeneity, aluminum resinate is used for precipitation Aluminum sulfate added. At the end you have to work with a ρκ value of 4.5. If the mixture has become really homogeneous, it runs through the paper machine without this the papermaking process is changing.

Es kann jedoch auch so verfahren werden, daß man die wie oben hergestellte Emulsion alsbald nach ihrer Herstellung mit einem Aluminiumsalz versetzt und das so gewonnene Produkt zur Verarbeitung bringt, wobei sich die spätere Ausfällung mit einem Aluminiumsalz erübrigt, wodurch das Verfahren noch weiter vereinfacht wird.However, it is also possible to proceed in such a way that the emulsion prepared as above is immediately used After their production, an aluminum salt is added and the product obtained in this way for processing brings, whereby the later precipitation with an aluminum salt is unnecessary, whereby the Procedure is further simplified.

Das nach dem vorliegenden Verfahren erhaltene Papier zeichnet sich durch eine hohe Undurchlässigkeit, die bei einem Paraffingehalt von wenigen Prozenten vollständig sein kann, und durch eine beträchtliche Verbesserung der Gleichmäßigkeit seiner Flächen aus.The paper obtained by the present process is characterized by high impermeability, which can be complete with a paraffin content of a few percent, and by a considerable amount Improve the evenness of its surfaces.
