Description

Verfahren zur Oberflächenveredlunq von Papier Durch Oberflächenveredlung sollen bei Papier die Poren geschlossen und ein Ausfließen von Tinte, Druckfarbe usw. verhindert werden. Gleichzeitig wird eine Verbesserung der mechanischen Eigenschaften, wie Naßfestigkeit, Glanz, Griff usw., angestrebt. Meist werden Stoffe, die diesen Zweck erreichen, sollen, bereits bei der Herstellung des Papiers hinzugesetzt (Papierleimung). Es sind aber auch Mittel bekannt, z. B. Firnisse, Harze, Leime, die in verdünnten Lösungen oder als Suspension auf das fertige Papier aufgetragen werden.Process for surface finishing of paper by surface finishing the pores of paper are supposed to be closed and ink and printing ink to flow out etc. can be prevented. At the same time, there is an improvement in the mechanical properties, such as wet strength, gloss, feel, etc., aimed for. Mostly substances that have this Achieve the purpose, should be added during the manufacture of the paper (paper sizing). But there are also known agents such. B. Varnishes, resins, glues that are diluted in Solutions or as a suspension can be applied to the finished paper.

Das vorliegende Verfahren gehört zu den letztgenannten Methoden. Es handelt sieh also um eine NTachbehandlung von fertigem Papier, das damit wesentlich verbessert wird. Nach der Erfindung sind besonders geeignete Präparate für die Oberflächenveredlung von Papier @d;ie Mischpolymerisate aus Maleinsäureanhydrid, aus dessen Halb- oder Diamiden, mit aromatischen Aminen und aus Vinyl#-verbindungen. Diese Mischpolymerisate werden vorteilhaft in Form .ihrer wasserlöslichen Salze, z. B. als Ammonium- oder Aminsalze, angewendet.The present procedure is one of the latter methods. It It is therefore a matter of a post-treatment of finished paper, which is therefore essential is improved. According to the invention are particularly suitable preparations for surface finishing von Papier @d; ie copolymers from maleic anhydride, from its semi- or Diamides, with aromatic amines and from vinyl # compounds. These copolymers are advantageously in the form of their water-soluble salts, e.g. B. as ammonium or Amine salts, applied.

Als Beispiel: sei ein Polymerisationsprodukt aus 30 Teilen Maleinsäureanhydrid, 2o Teilen Maleinsäurehalban.ilid und 5o Teilen, Styrol genannt, das als wasserlösliches Ammoniumsalz auf das Papier gebracht wird. Die Darstellung des Präparats kann auch so erfolgen, da.ß man beispielsweise zunächst Maleinsäurcan:hydrid mit Styrol polymerisiert, dann .durch Umsetzung mit Anilin zoo/o der Carboxylgruppen amidiert und die restlichen, Carboxyle mit Ammoniak neutralisiert. In besonderen Fällen können diese Polymerisate direkt ohne Überführung in wasserlösliche Salze in organischen Lösemitteln, wie Aceton, Methyläthylketon usw., angewendet werden.An example is a polymerization product made from 30 parts of maleic anhydride, 20 parts of maleic acid halide and 50 parts, styrene, which is applied to the paper as a water-soluble ammonium salt. The preparation can also be prepared in such a way that, for example, maleic acid hydride is first polymerized with styrene, then 100% of the carboxyl groups are amidated by reaction with aniline and the remaining carboxyls are neutralized with ammonia. In special cases, these polymers can be used directly without being converted into water-soluble salts in organic solvents, such as acetone, methyl ethyl ketone, etc.

Die Verwendung von Maleinsäur,e-Styrol-Mischpolymerisaten und ihrer Teilester als Überzugsmittel und für die Lackherstellung ist seit kurzem bekannt (vgl. französisches Patent 957 oo5). Die Salze dieser Verbindung haben jedoch gegenüber dem in verdünnter wäßriger Lösung angewandten tierischen Leim oder Blutalbumin eine relativ geringe Klebkraft. Während nun die Umsetzungsprodukte mit aliphatischen Aminen überhaupt keine klebende Wirkung aufweisen, hat sich gezeigt"daß durch Eintritt von aromatischen Aminen in das Molekül der Polystyrolmaleinsäure eine beträchtliche Zunahm,-, der Klebkraft eintritt, welche die des tierischen Leims erreicht bzw. übertrifft. Die beanspruchten: Mischpolymerisate haben sich als ganz besonders vorteilhaft für die Oberflächenveredlung von Papier, gegebenenfalls mit anderen Zusätzen, erwiesen. Es wurde gefunden, daß sich für den angestrebten Zweck .Anilin besonders eignet, und zwar werden 5 bis. 400/e, am besten etwa z o °/o der gesamtem Carboxylgruppen des Polymerisats damit amidiert: Andere aromatische Amine, wie Toluidin und Xylidin usw., können ebenfalls verwendet werden.- Ebenso kann man an. Stelle von Styrol andere Vinylverbindungen oder Gemische aus Styrol und anderen Vinylverbindungen; beispielsweise Vinylchlori,d; für den beanspruchten Zweck mit Mal,einsäureanhydri-d; polynmerisieren und partiell mit .aromatischen Aminen umsetzen oder gleich mit Gemischen aus aleinsäureanhydrid und deren Halbami-den. oder Diamiden polymerisieren.The use of maleic acid, e-styrene copolymers and their Partial esters as a coating agent and for paint production have recently been known (see French patent 957 oo5). However, the salts of this compound have opposite the animal glue or blood albumin used in a dilute aqueous solution relatively low bond strength. While now the reaction products with aliphatic Amines have no adhesive effect at all, it has been shown "that by entry of aromatic amines in the molecule of polystyrene maleic acid a considerable amount Increase, -, the adhesive force occurs, which reaches that of animal glue or surpasses. The claimed: copolymers have proven to be particularly advantageous proven for the surface finishing of paper, possibly with other additives. It has been found that aniline is particularly suitable for the intended purpose, namely 5 to. 400 / e, preferably about z o% of the total carboxyl groups of the polymer amidated with it: Other aromatic amines such as toluidine and xylidine etc., can also be used.- Likewise one can at. Place of styrene other vinyl compounds or mixtures of styrene and other vinyl compounds; for example vinylchlori, d; for the claimed purpose with Mal, Einsäureanhydri-d; polymerize and partially react with aromatic amines or with mixtures from aleic anhydride and its hemi-amides. or polymerize diamides.
