Description

Kunststoffpapier aus einer impräg- Plastic paper made from an

nierten Papierbahn Die Erfindung betrifft ein Kunststoffpapier aus einer imprägnierten, mit Pigmenten und Füllstoffen versehenen Papierbahn, das sich durch sehr hohe Festigkeit, Lichtechtheit, KnitterSestigkeit, Stanz-und Prägefähigkeit sowie gute Bedruckbarkeit auszeichnet . ned paper web The invention relates to a plastic paper an impregnated paper web provided with pigments and fillers, which due to very high strength, lightfastness, crease resistance, punching and embossing ability as well as good printability.

Es ist bekannt, Papiere auf unterschiedlichste Art und Weise herzustellen und so nachzubehandeln, daß sie für die jeweiligen Anwendungszwecke geeignet sind. So werden beispielsweise solche Papiere, die eine hohe Reißfestigkeit besitzen und im Gegensatz zu herkömmlichen Papieren feuchtigkei tsunempfindlicher sind, rein aus Synthesefasern hergestellt.It is known to produce papers in a wide variety of ways and to be post-treated in such a way that they are suitable for the respective application purposes. For example, those papers that have a high tear strength and in contrast to conventional papers, they are less sensitive to moisture, pure made from synthetic fibers.

Die Bedruckbarkeit solcher Produkte ist jedoch problematisch und meist nur mit Spezialdruckfarben zufriedenstellend. Zudem sind zur Herstellung solcher Kunststoffpapiere tiefgreifende konstruktive Veranderungei einer konventionellen Papi ermaschine notwendig und es müssen deutlich niedrigere Produktionsgeschwindigkeiten in Kauf genommen werden. Dagegen zeigen allein aus Zellulosefasern hergestellte, insbesondere gestricllene Papiere, eiiie gute Bedruckbarkeit sowohl mit Lösungsmittelfarben, als auch mit wäßrigen Systemen. Ihre Widerstandsfähigkeit gegenüber Feuchtigkeit und Chemikalien sowie gegenüber mechanischer Beanspruchung (wie z.B. Falzfestigkeit, Ein- und Weiterreißfestigkeit) ist jedoch gering.However, the printability of such products is problematic and mostly only satisfactory with special inks. In addition, for the production of such Plastic papers Far-reaching constructive change in a conventional paper machine is necessary and significantly lower production speeds have to be accepted will. In contrast, those made solely from cellulose fibers, especially knitted ones, show Papers, good printability both with solvent inks and with aqueous systems. Their resistance to moisture and chemicals as well as against mechanical stress (such as folding strength, tear strength and tear strength) however, it is minor.

Der vorliegenden Erfindung wiegt die Aufgabe zugrunde, ein bahnförmiges Material zu schaffen, welches, Der gestellt auf einer konventionellen Papiermaschine, die wesentlichen Merkmale sowohl eines Papieres als auch die einer Kunststoffolie gleichermaßen aufweist.The present invention is based on the object of a web-shaped To create material, which, placed on a conventional paper machine, the essential characteristics of both a paper and a plastic film equally has.

Die Lösung der gestellten Aufgabe wurde erf:indungsgemäß dadurch erreicht, daß die Papierbaini vorwiegend unter Verwendung von Langfaser-Zellstoffen hergestellt und einer Imprägnierung mit einer wäßrigen Acrylharz-Dispersion auf Basis selbstvernetzender Acrylsäureester unterzogen wurde.According to the invention, the solution to the problem posed was achieved by that the paper baini is mainly made using long fiber pulp and an impregnation with an aqueous acrylic resin dispersion based on self-crosslinking Acrylic acid ester was subjected.

Das hierbei erhaltene Kunststoffpapier zeichnet sich durch folgende Eigenschaften aus: hohe Wasserfestigkeit - Flexibilität - Lichtechtheit - Reißfestigkeit - Knautsch- und Knitterfestigkeit - hohe Falzzahl - Dimensionsstabilität - Prägbarkeit sowie eine sehr gute Bedruckbarkeit.The plastic paper obtained in this way is characterized by the following Properties from: high water resistance - flexibility - lightfastness - tear resistance - Crumple and crease resistance - high number of folds - dimensional stability - embossability as well as very good printability.

Die Festigkeit der Papierbahn kann durch die Mitverwendung voii 0,5 bi.' 30 %, vorzugsweise 15 bis 25 %, von Kunstfasern, insbesondere von Polyesterfasern, erheblich gesteigert werden.The strength of the paper web can be increased by using 0.5 bi.' 30%, preferably 15 to 25%, of synthetic fibers, in particular of polyester fibers, can be increased considerably.

Die Imprägnierlösung enthält 30 bis 60 Gew.-% von Acrylharz-Dispersionen auf Basis selbstvernetzender Acrylsäureester. Eine Modifizierung durch Zugabe von Aminoplastharzen in einer Menge von 1 bis 20 Gew.-% zur Imprägnierlösung kann von Vorteil sein.The impregnation solution contains 30 to 60% by weight of acrylic resin dispersions based on self-crosslinking acrylic acid esters. Modification by adding Aminoplast resins in an amount of 1 to 20% by weight to the impregnation solution can be from Be an advantage.

Die Zusammensetzung der eingesetzten KllllststoSle wird so gewählt, daß der Kunststoffanteil 15 bis 40 % des Papierrohgewichtes beträgt.The composition of the used plastic is chosen so that that the plastic content is 15 to 40% of the raw paper weight.

Es ist außerdem günstig, zur Imprägnierlösung wasserlö sl i c1ie El @@rverbindungen in ein er Menge von 2 bis 10 Gew.-% zuzusetzen. Dafür eignen sich insbesondere polymere, wäßrige Emulsionen fluorierter Harze (z.B. Fluorcarbonharze). Dadurch wird dem Kullststoffpapier eine öl-, fett- und wasserabweisende Eigenschaft verliehen, ohne seine sonstigen Eigenschaften negativ zu beeinflussen.It is also advantageous to use water-lo sl i c1ie El Adding compounds in an amount of 2 to 10% by weight. Are suitable for this in particular polymeric, aqueous emulsions of fluorinated resins (e.g. fluorocarbon resins). This gives the plastic paper an oil, grease and water repellent property awarded without adversely affecting its other properties.

Schließlich können der Imprägnierlösung Wachsemulsionen beigefügt werden. Durch diese Zusätze werden eine bessere Wasserbeständigkeit sowie höherer Glanz und Glätte erreicht. Die Zugabe erfolgt in einer Menge von 1 bis 10 Gew.-% bezogen auf den Kunststoffanteil im Papier.Finally, wax emulsions can be added to the impregnation solution will. Through these additives a better water resistance as well as higher Achieved gloss and smoothness. The addition takes place in an amount of 1 to 10 wt .-% based on the plastic content in the paper.

Als Gleitmittel werden bevorzugt iii Wasser emulgierbare Wachs verwendet. Ebenso können Salze organischer Fettsäure-Derivate verwendet werden.The lubricants used are preferably iii water-emulsifiable wax. Likewise, salts can be more organic Fatty acid derivatives can be used.

Durch eine nachfolgende Kalandrierung können nach dem beschriebenen Verfahren hergestellte Kunststoffpapiere optisch und technisch wesentliche beeinflußt werden.Subsequent calendering can after the described Process produced plastic papers visually and technically significantly influenced will.

Beispiel 1 Eine Papierbahn wurde aus einem L&ngfa ser-Zell stoff und einer Kunststoff-Faser hergestellt. Als Füllstoffe wurde übliche Titandioxide und Clays in einer Menge von 20 % eingesetzt. Der Anteil an Eangfaser betrag 80 %, der Anteil an Kunststoff-Fasern 20 %, Die Papierbahn wurde mit einer wäßrigen, selbstvernetzendell Acrylat-Dispersion imprägniert. Der Harzgehalt des imprägnierten Papieres betrug 40 0% bezogen auf das Papiergewicht. Example 1 A paper web was made from a long fiber pulp and a plastic fiber. Usual titanium dioxide was used as filler and clays used in an amount of 20%. The proportion of input fiber is 80 %, the proportion of synthetic fibers 20%, the paper web was washed with an aqueous, self-crosslinking acrylic dispersion impregnated. The resin content of the impregnated Paper was 40% based on the weight of the paper.

Nach dem Trocknen entsteht ein Kunststoffpapier mit hoher Wasserfestigkeit, guter Bedruckbarkeit, Lichtechtheit und hoher Dehnfähigkeit.After drying, the result is a plastic paper with high water resistance, good printability, lightfastness and high elasticity.

Beispiel 2 Bei der Herstellung der Papierbahn nach dem Beispiel 1 werden 20 % Polyesterfasern zugegeben. Die Imprägnierung wird mit einer Lösung bestehend aus 35 Gew.-einer selbstvernetzenden Acrylharzdispersion und 2 Gew.-* eines Aminoplastharzes durchgeführt. Es wird eine Papierbahn mit ausgezeichneter Dimensionsstabilität und Reißfestigkeit erhalten. Example 2 In the production of the paper web according to Example 1 20% polyester fibers are added. The impregnation is made up of a solution from 35% by weight of a self-crosslinking acrylic resin dispersion and 2% by weight of an aminoplast resin carried out. It becomes a paper web with excellent dimensional stability and Preserved tear strength.
