An impregnating agent is used to produce grease-proof and oil-proof recyclable papers with high resistance against the penetration of aqueous media. Besides the state-of-the-art perfluorocompounds and glueing agents, a waterproofed precipitation silicic acid and an aliphatic-aromatic polyester-polyurethane dispersion are used.

Description

Imprägniermittel zur Herstellung von Papieren mit hohem Durchdringungswiderstand gegen Fette, öle und wässrige MedienImpregnation agent for the production of papers with high penetration resistance against fats, oils and aqueous media
Die Erfindung betrifft ein Mittel zur Herstellung von imprägnierten Papieren innerhalb oder außerhalb der Pa¬ piermaschine, mit welchem dem Papier auf dem Wege der Oberflächenveredlung hohe Durchdringungswiderstände ge¬ gen Fette, öle und wässrige Medien verliehen werden.The invention relates to an agent for the production of impregnated papers inside or outside the paper machine, with which the paper is given high penetration resistance to fats, oils and aqueous media by means of surface finishing.
Bekannt sind verschiedene technische Verfahren zur fett- und wasserdichten Ausrüstung von Papieren innerhalb und außerhalb der Papiermaschine. Innerhalb der Papiermaschi¬ ne werden zu diesem Zweck Kombinationen von Stärkelösunl5 gen und/oder Polyvinylalkohollösungen mit Zusätzen von Fluorchemikalien, synthetischen Hydrophobierungsmitteln, wie Alkylketendimerleime und/oder Copolymerisatleime aus Styrol- und Butylacrylaten unter Zusatz verschiedener Vernetzer, wie Glyoxal , Melaminformaldehydharze bzw. Epi- chlorhydrinharze verwendet.Various technical processes for the grease and waterproof finishing of papers inside and outside the paper machine are known. For this purpose, combinations of starch solutions and / or polyvinyl alcohol solutions with additions of fluorochemicals, synthetic water repellents, such as alkyl ketene dimer glues and / or copolymer glues from styrene and butyl acrylates with the addition of various crosslinking agents, such as glyoxal, melamine formaldehyde resins or epichlorohydrin, are used within the paper machine for this purpose used.
Diese Zusammensetzung von Imprägniermedien gestattet zwar die Herstellung von Papieren mit hoher Fettdichte, jedoch die Wasserdichte entspricht oft noch nicht den anwen- dungstechnischen Forderungen.Although this composition of impregnation media permits the production of papers with a high fat density, the water density often does not yet meet the application requirements.
Bekannt sind weiterhin Imprägniermedien zur Beschichtung von Papieren innerhalb und außerhalb von Papiermaschinen, die Silikonöldispersionen und/oder Silikonwachsdispersio¬ nen enthalten. Mit diesen Imprägnierungen werden dem Pa- pier zwar sehr gute Durchdringungswiderstände gegen Fet¬ te, öle und auch wässrige Medien verliehen, jedoch nehmen die so behandelten Papiere keine Klebstofflösungen mehr an und sind somit anwendungstechnisch nicht für die Herstellung von Verbundmaterialien geeignet. Bekannt sind weiterhin Verfahren zur fett- und wasser¬ dichten Veredlung von Papieren außerhalb der Papierma¬ schine, bei denen die Dichtheitsmerkmale durch Disper- sions- oder Extrusionsbeschichtungen oder auch durch Kaschieren mit Metall- oder Plastikfolien oder auch durch Bedampfen mit Metall erreicht werden. Alle diese Verfahren und Mittel bewirken zwar hohe Durchdringungs¬ widerstände gegen Fette, öle und wässrige Medien, er- schweren jedoch stark die Recyclefähigkeit der Produkte.Impregnation media for coating papers inside and outside of paper machines which contain silicone oil dispersions and / or silicone wax dispersions are also known. With these impregnations, the paper is given very good penetration resistance to fats, oils and also aqueous media, but the papers treated in this way no longer accept adhesive solutions and are therefore not suitable for the application Production of composite materials suitable. Methods are also known for the grease and water-tight finishing of papers outside the paper machine, in which the tightness features are achieved by dispersion or extrusion coatings or also by lamination with metal or plastic films or also by vapor deposition with metal. All of these methods and agents have high penetration resistance to fats, oils and aqueous media, but make the products more difficult to recycle.
Die Erfindung hat zum Ziel, ein Imprägniermittelsystem zu gestalten zur Herstellung von fett-, öl- und wasser dichten, recyclebaren Papieren innerhalb und außerhalb der Papiermaschine.The aim of the invention is to design an impregnation system for the production of grease, oil and water-tight, recyclable papers inside and outside the paper machine.
Der Erfindung liegt die Aufgabe zugrunde, ein Imprägnier¬ medium zur Herstellung von fettdichten, öldichten, was¬ serdichten und dennoch recyclebaren Papieren innerhalb und außerhalb der Papiermaschine zu entwickeln, das ge¬ genüber dem Stand der Technik von innerhalb der Papier¬ maschine angewendeten Imprägniermedien, bei Beibehaltung der Fettdichte, einen erhöhten Durchdringungswiderstand gegen Wasser bewirkt und dennoch ein ausreichende Auf- nahmefähigkeit für Kaschierklebstoffe sichert.The invention is based on the object of developing an impregnating medium for producing greaseproof, oilproof, waterproof and nevertheless recyclable papers inside and outside the paper machine, which compared to the prior art of impregnating media used inside the paper machine, while maintaining the fat density, it increases the penetration resistance against water and still ensures sufficient absorption capacity for laminating adhesives.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß einer vorbereiteten Polyvinylalkohollösung von 2 bis 6 % Konzentration, vorzugsweise 3 %, 3 bis 10 Volumenprozent bezogen auf die Polyvinylalkohollösung, vorzugsweise 6 % einer anionischen aliphatisch-aromatischen Polyester- Polyurethan-Dispersion der Shore A-Härte von 40 bis 60 und des Molmassenbereiches von 10.000 bis 30.000 und einer Konzentration von 40 % zugegeben und eingemischt werden, daß der nun vorliegenden Mischung eine gesondert vorbereitete Mischung, bestehend aus 5 bis 20 Massepro¬ zent bezogen auf Polyvinylalkohol , vorzugsweise 15 %, in Methanol angeteigter hydrophobierter Fällungskieselsäure und 1 bis 3 Volumenprozent bezogen auf die Polyvinylalko hollösung, vorzugsweise 2„%, einer anionischen Akylketen dimer-Dispersion mit einer Konzentration von 11 % und einer Teilchengröße von 0,2 bis 0,9 Mikron, zugesetzt un gut eingemischt wird, der nun vorliegenden Mischung 0,5 bis 3 Volumenprozent bezogen auf die Polyvinylalkohol¬ lösung, vorzugsweise 2 %, einer anionischen Perfluor- alkylethylphosphat-Diethanolam oniumsalzlösung in Isopro- pylalkohol mit einer Konzentration von 33 % zugegeben un eingemischt werden und daß abschließend der nun vorlie¬ genden Mischung 0,2 bis 1,0 Volumenprozent bezogen auf die Polyvinylalkohollösung, vorzugsweise 0,5 %, Glyoxal zugesetzt und eingemischt werden und diese Gesamtmischun zur Papierimprägnierung innerhalb der Papiermaschine ver wendet wird.According to the invention the object is achieved in that a prepared polyvinyl alcohol solution of 2 to 6% concentration, preferably 3%, 3 to 10 volume percent based on the polyvinyl alcohol solution, preferably 6% of an anionic aliphatic-aromatic polyester-polyurethane dispersion of Shore A hardness of 40 to 60 and the molecular weight range from 10,000 to 30,000 and a concentration of 40% is added and mixed in that the mixture now present is a separately prepared mixture consisting of 5 to 20 percent by mass based on polyvinyl alcohol, preferably 15%, made of hydrophobicized precipitated silica in methanol and 1 to 3 percent by volume based on the polyvinyl alcohol dole solution, preferably 2%, an anionic Akylketen dimer dispersion with a concentration of 11% and a particle size of 0.2 to 0.9 micron, is added and mixed in well, the mixture now present 0.5 to 3 volume percent based on the polyvinyl alcohol solution, preferably 2%, of an anionic perfluoroalkylethylphosphate-diethanolam onium salt solution in isopropyl alcohol with a concentration of 33% is added and mixed in and that finally the mixture presently present is 0.2 to 1.0 percent by volume based on the polyvinyl alcohol solution, preferably 0.5%, glyoxal added and mixed in and this total mixture is used for paper impregnation within the paper machine.
Die Verwendung dieses Imprägniermediums zur Imprägnierun von Papier innerhalb der Papiermaschine mit einem der bekannten Auftragsverfahren und anschließender Trocknung in der Nachtrockenpartie gestattet die Herstellung von fett- und öldichten, recyclebaren Papieren, die zudem infolge der anteiligen Verwendung einer anionischen Poly ester-Polyurethan-Dispersion und einer hydrophobierten Fällungskieselsäure einen sehr hohen Durchdringungswider stand gegen wässrige Medien besitzen.The use of this impregnation medium for the impregnation of paper within the paper machine with one of the known application methods and subsequent drying in the after-dryer section allows the production of grease and oil-tight, recyclable papers, which are also due to the proportionate use of an anionic polyester-polyurethane dispersion and hydrophobic precipitated silica have a very high penetration resistance against aqueous media.
