Description

Verfahren zur Leimung von Papier im Stoff Im Hauptpatent 663 445 ist ein Verfahren zur Harzleimung von Papier im Stoff unter Mitverwendung von polymeren wasserlöslichen Säureamiden beschrieben.Process for the sizing of paper in the fabric in the main patent 663 445 is a process for resin sizing paper in the fabric with the use of polymers water-soluble acid amides described.

Es wurde nun gefunden, daß man auch die Wachsleimung von Papier im Stoff wesentlich verbessern kann, wenn man die im Hauptpatent genannten polymeren wasserlöslichen Amide ungesättigter Carbonsäuren mitverwendet. Es können hierbei die bei der Papierleimung üblichen Wachse zur Anwendung gelangen, insbesondere Montanwachse und durch oxydative Behandlung daraus erhaltene hochmolekulare Carbonsäuren. Die Säureamide können bereits den Wachsen beigemischt oder auch erst bei ,der Leimung des Papierstoffes im Holländer zugesetzt werden. Man kann auch gleichzeitig noch andere bekannte Leimstoffe, z. B. Casein oder Wasserglas, mitvenvende#a.It has now been found that the wax sizing of paper in the Substance can be improved significantly if you use the polymers mentioned in the main patent water-soluble amides of unsaturated carboxylic acids are also used. It can do this the waxes customary in paper sizing are used, in particular montan waxes and high molecular carboxylic acids obtained therefrom by oxidative treatment. the Acid amides can already be added to the waxes or only during gluing of the paper stock can be added in the Hollander. You can also at the same time other known glues, e.g. B. Casein or water glass, also use # a.

Durch die Mitverwendung der wasserlöslichen polymeren Säurearnidde wird eine wesentliehe Ersparnis an Wachsen erzielt. Die mechanischen Festigkeiten des so geleimten Papiers sind infolge des geringeren Wachszusatzes wesentlichhöher als bei den beider bisher üblichen Wachsleimung erhaltenen Papieren. Das Verfahren eignet sich in gleicher Weise wie das Verfahren des Hauptpatents auch vorteilhaft für hochgefüllte Papiere.By using the water-soluble polymeric acid amide a substantial saving in wax is achieved. The mechanical strengths of the paper sized in this way are significantly higher due to the lower addition of wax than with the papers obtained with the two previously customary wax sizes. The procedure is also advantageous in the same way as the method of the main patent for highly filled papers.

Es ist bekannt, wäßrige Dispersionen von Polyacrylestern der Papiermasse im Holländer zuzusetzen. Man erhält so Wasser- und öldichte Papiere. Man hat auch schon vorgeschlagen, Mischungen von Harzen, insbesondere Kolophonium, also einer Harzsäure, und Wachsen zum Leimen von Papier zu verwenden. Die Polyacrylester wie auch Kolophonium sind wasserunlöslich und üben für sich allein eine leimende Wirkung auf die Papiermasse aus. Die polymeren Säureamide sind jedoch wasserlöslich und besitzen für sich keine leimende Wirkung auf die Papiermasse. Die Mitverwenduu,g der wasserlöslichen polymeren Amide ungesättigter C'arbans.äuren bei der Wachsleimung bringt überdies den unerwarteten Vorteil mit sich, daß m.an nur verhältnismäßig geringe Mengen an , leimendem Mittel zu verwenden braucht ünrj: trotzdem eine gute Leimung, insbesondei auch bei hochbeschwerten Papieren, erhä Auch die Festigkeitseigenschaften des Papiers werden dabei gesteigert. Beispiel Zu 3oo Teilen im Holländer befindlichem Papierstoff gibt man 6 Teile oxydiertes Montanwachs in emulgierter Form, mischt gut durch und fügt noch etwa 3 Teile oder auch weniger polymeres Acrylsäureamid in Wasser gelöst hinzu. Nach weiterem Durchmischen der Masse gibt man noch ungefähr 6 Teile Aluminiumsulfat zu. Der Papierstoff kann in in üblicher Weise .auf Papier verarbeitet Dieses zeichnet sich durch eine volle und besonders feste Beschaffenheit 7ä@s. It is known to add aqueous dispersions of polyacrylic esters to the paper pulp in the Hollander. In this way, water- and oil-tight papers are obtained. It has also been proposed to use mixtures of resins, in particular rosin, that is to say a resin acid, and waxes to glue paper. The polyacrylic esters as well as rosin are insoluble in water and have a sizing effect on their own on the paper pulp. However, the polymeric acid amides are water-soluble and do not have any sizing effect on the paper pulp. The use of the water-soluble polymeric amides of unsaturated carbanic acids in wax sizing also has the unexpected advantage that only relatively small amounts of sizing agent need to be used heavily weighted papers, the strength properties of the paper are also increased. EXAMPLE 6 parts of oxidized montan wax in emulsified form are added to 300 parts of paper stock in the Dutch, mix well and add about 3 parts or more less polymeric acrylic acid amide in water solved added. After further mixing add about 6 parts to the mass Aluminum sulfate too. The paper stock can processed in the usual way on paper This is characterized by a full and particularly firm texture 7ä @ s.
