Abstract

Paper production, impregnating agent, polyester-polyurethane dispersion, waterproofed precipitation silicic acid, perfluoroalkylethyl phosphatediethanol ammonium salt, styrene-butyl acrylate copolymer, alkyl ketene dimer dispersion, grease-proofing and water-proofing are disclosed. 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

Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung betrifft ein Mittel zur Herstel­ lung von imprägnierten Papieren innerhalb oder außerhalb der Papiermaschine, mit welchem dem Papier auf dem Wege der Oberflächenveredlung hohe Durchdringungswiderstände gegen Fette, Öle und wäßrige Medien verliehen werden.The invention relates to a means of manufacture treatment of impregnated papers within or outside the paper machine with which Paper on the way of surface finishing high penetration resistance to greases, Oils and aqueous media are awarded.

Charakteristik der bekannten technischen LösungenCharacteristic of the known technical solutions

Bekannt sind verschiedene technische Verfahren zur fett- und wasserdichten Ausrüstung von Pa­ pieren innerhalb und außerhalb der Papierma­ schine. Innerhalb der Papiermaschine werden zu diesem Zweck Kombinationen von Stärkelösungen und/oder Polyvinylalkohollösungen mit Zusätzen von Fluorchemikalien, synthetischen Hydropho­ bierungsmitteln, wie Alkylketendimerleime und/ oder Copolymerisatleime aus Styrol- und Butyl­ acrylaten unter Zusatz verschiedener Vernetzer, wie Glyoxal, Melaminformaldehydharze bzw. Epi­ chlorhydrinharze verwendet. Various technical processes are known for grease and waterproof equipment from Pa paper inside and outside the paper machine seem. Inside the paper machine are too combinations of starch solutions and / or polyvinyl alcohol solutions with additives of fluorochemicals, synthetic hydropho agents, such as alkyl ketene dimer and / or copolymer glues from styrene and butyl acrylates with the addition of various crosslinkers, such as glyoxal, melamine formaldehyde resins or epi chlorohydrin resins used.  

Diese Zusammensetzungen von Imprägnierme­ dien gestatten zwar die Herstellung von Pa­ pieren mit hoher Fettdichte, jedoch die Was­ serdichte entspricht oft noch nicht den an­ wendungstechnischen Forderungen.These compositions of impregnation although they allow the production of pa high fat density, but the what Often, density does not match that technical requirements.

Bekannt sind weiterhin Imprägniermedien zur Beschichtung von Papieren innerhalb und außer­ halb von Papiermaschinen, die Silikonöldisper­ sionen und/oder Silikonwachsdispersionen ent­ halten. Mit diesen Imprägnierungen werden dem Papier zwar sehr gute Durchdringungswiderstände gegen Fette, Öle und auch wäßrige Medien ver­ liehen, jedoch nehmen die so behandelten Pa­ piere keine Klebstofflösungen mehr an und sind somit anwendungstechnisch nicht für die Her­ stellung von Verbundmaterialien geeignet. Bekannt sind weiterhin Verfahren zur fett- und wasserdichten Veredlung von Papieren außerhalb der Papiermaschine, bei denen die Dichtheits­ merkmale durch Dispersions- oder Extrusionsbe­ schichtungen oder auch durch Kaschieren mit Me­ tall- oder Plastikfolien oder auch durch Be­ dampfen mit Metall erreicht werden. Alle diese Verfahren und Mittel bewirken zwar hohe Durch­ dringungswiderstände gegen Fette, Öle und wäßrige Medien, erschweren jedoch stark die Recyclefähigkeit der Produkte. Impregnation media are also known for Coating of papers inside and outside half of paper machines, the silicone oil disperser ent and / or silicone wax dispersions ent hold. With these impregnations Paper has very good penetration resistance against fats, oils and also aqueous media lent, but the Pa no longer apply and are therefore not for the application technology suitable composite materials. Methods for fat and are also known waterproof finishing of papers outside the paper machine where the tightness characteristics by dispersion or extrusion layers or by lamination with Me tall or plastic foils or also by Be Vaping can be achieved with metal. All these Procedures and means cause high throughput penetration resistance to greases, oils and aqueous Media, however, make it very difficult Recyclability of the products.  

Ziel der ErfindungAim of the invention

Die Erfindung hat sich das Ziel gestellt, ein Imprägniermittelsystem zu gestalten zur Her­ stellung von fett-, öl- und wasserdichten, recyclebaren Papieren innerhalb oder außerhalb der Papiermaschine.The invention has set itself the goal of To design impregnating agent system positioning of grease, oil and watertight recyclable papers inside or outside the paper machine.

Darlegung des Wesens der ErfindungState the nature of the invention
