Abstract

Verfahren zur Imprägnierung von Cellulosepapieren bzw. Formkörpern aus Cellulosepapieren mit hydrophilen anorganischen Salzen, die als Flammschutzmittel, zur hygroskopischen Konditionierung bzw. als Korrosionsinhibitoren dienen können, dadurch gekennzeichnet, dass die Tränkung mit organischen Lösungen der einzubringenden Salze erfolgt.Process for the impregnation of cellulose papers or moldings of cellulose papers with hydrophilic inorganic salts, which can serve as flame retardants, for hygroscopic conditioning or as corrosion inhibitors, characterized in that the impregnation with organic solutions of the salts to be incorporated takes place.

Description

Das erfindungsgemäße Verfahren dient der Imprägnierung von Cellulosepapieren bzw. Formkörpern aus Cellulosepapieren durch Tauchtränkung.The process according to the invention serves to impregnate cellulose papers or shaped bodies of cellulose papers by immersion impregnation.

Die Imprägnierung von Papier erfolgt bei hydrophilen Wirkstoffen mittels wäßriger Lösungen bzw. Suspensionen. Dabei wird bei der Oberflächenimprägnierung das Imprägniermittel auf die Oberfläche aufgebracht und dringt von dort ins Material ein. In der Regel wird das Material vollständig vom Imprägniermittel durchtränkt. Die Imprägnierung liegt damit homogen verteilt vor. Die Papierbahn wird im allgemeinen kontinuierlich durch ein Tauchbad mit Imprägnierlösung geführt und nach Abquetschen oder Abstreichen überschüssigen Imprägniermittels in Walzen- oder Kanaltrocknern getrocknet. Abroll- und Aufrolleinrichtungen ergänzen die technologische Anlage.The impregnation of paper takes place with hydrophilic active substances by means of aqueous solutions or suspensions. In the case of surface impregnation, the impregnating agent is applied to the surface and penetrates from there into the material. As a rule, the material is completely impregnated by the impregnating agent. The impregnation is thus homogeneously distributed. The paper web is generally passed continuously through a dipping bath with impregnating solution and dried after squeezing or wiping off excess impregnating agent in roll or channel driers. Roll-off and roll-up devices complete the technological system.

Alternativ zur Tauchimprägnierung kann das Imprägniermittel auch aufgewalzt oder aufgesprüht werden. Nach Egalisierung des Auftrages erfolgt die Trocknung.As an alternative to dip impregnation, the impregnating agent can also be rolled or sprayed on. After equalization of the order, the drying takes place.

Es sind auch Verfahren bekannt geworden, wo die Sprühimprägnierung in die Papierherstellung integriert wurde. In der DD 150 399 wird z. B. ein Verfahren zur Herstellung eines flammfesten Papieres beschrieben, bei dem das Flammschutzmittel zwischen Sieb- und Trockenpartie einer Papiermaschine auf eine kalte, laufende Papierbahn mit Hilfe eines Düsenstockes aufgesprüht wird und anschließend die so ausgerüstete Papierbahn in bekannter Weise in der Trockenpartie getrocknet wird.Methods have also become known where spray impregnation has been integrated into papermaking. In the DD 150 399 is z. Example, a method for producing a flame-resistant paper, in which the flame retardant between the wire and dryer section of a paper machine is sprayed onto a cold, running paper web using a nozzle and then the paper web thus treated is dried in a known manner in the dryer section.

Bei Formkörpern aus Papier erfolgt die Imprägnierung meist diskontinuierlich durch Tauchtränkung. Ein großes Problem bei der Tränkung mit wäßrigen Imprägniersystemen ist die Beeinflussung der mechanischen Stabilität der Cellulosepapiere bzw. der daraus hergestellten Formkörper. Die Minderung der Reißkraft und die Quellung des Materials, insbesondere quer zur Bahnrichtung der Papiere, haben zur Folge, dass manche Papiere einer Tauchimprägnierung nicht standhalten. Geeignete Naßfestmittel bzw. Leimung der Papiere sollen die Eigenschaften so verbessern, dass nachfolgende Tränkungen möglich sind. Durch solche chemischen Hilfsmittel, die über den Stoff ins Papier eingebracht werden, kommt es oft zu negativen Beeinträchtigungen der Saughöhe und der Oberflächensaugfähigkeit (Cobb-Test), wodurch auch das Aufnahmevermögen für Imprägniermittel leidet.For molded articles made of paper, the impregnation is usually discontinuous by immersion impregnation. A major problem with impregnation with aqueous impregnation systems is the influence on the mechanical stability of the cellulose papers or of the molded articles produced therefrom. The reduction of the tensile strength and the swelling of the material, in particular transversely to the web direction of the papers, have the consequence that some papers do not withstand a dip impregnation. Suitable wet strength or sizing of the papers to improve the properties so that subsequent impregnations are possible. Such chemical agents that are introduced into the paper via the fabric often result in negative suction height and surface wicking (Cobb test), which also suffers the ability to absorb impregnants.

Aufgabe der Erfindung ist es, das Verfahren der Tauchimprägnierung von Papieren bzw. Formkörpern aus Papier so zu verändern, dass die genannten negativen Begleiterscheinungen wesentlich vermindert werden bzw. dass eine Imprägnierung überhaupt möglich gemacht wird.The object of the invention is to modify the process of Tauchimpregnnierung of papers or moldings made of paper so that the said negative side effects are substantially reduced or that an impregnation is made possible at all.

Die Aufgabe wird durch die Merkmale der Patentansprüche gelöst, indem mit organischen Imprägnierlösungen gearbeitet wird. Vorzugsweise wird Methanol bzw. Ethanol als Lösungsmittel verwendet. Der weitgehende Verzicht auf das Lösungsmittel Wasser trotz des hydrophilen Charakters der eigentlichen Imprägniersubstanzen führt dazu, dass die vorstehend genannten Nachteile wäßriger Imprägniersysteme, wie Dehnungserscheinungen im Papier und Veränderungen der mechanischen Eigenschaften, vollständig vermieden werden können.The object is solved by the features of the claims by working with organic impregnation solutions. Preferably, methanol or ethanol is used as the solvent. The substantial absence of the solvent water despite the hydrophilic character of the actual impregnating substances leads to the fact that the aforementioned disadvantages of aqueous impregnation systems, such as elongation phenomena in the paper and changes in the mechanical properties, can be completely avoided.
