Bisher hat man Mischungen aus Polyurethan und Polyacrylat in organischen Lösungsmitteln zum Grundieren von Kunststoffen verwendet. Die Lösungsmittel wirken jedoch mehr oder weniger stark zerstörend auf die Kunststoffe ein. Hinzu kommt, daß das verdunstende Lösungsmittel umweltfeindlich ist.So far, mixtures of polyurethane and polyacrylate in organic solvents have been used for priming used by plastics. However, the solvents have a more or less destructive effect the plastics one. In addition, the evaporating solvent is harmful to the environment.
Weiterhin ist es aus der US-PS 42 78 578 bekannt, daß im Wasser dispergierte Polyurethane, welche ionische Gruppen enthalten, mit Härtern (Aziridinen) vernetzt werden können. Außerdem können die Dispersionen mit Acryl-, Alkyd- oder Vinyl-Latices gemischt werden. Ferner wird in der US-PS darauf hingeweisen, daß die polyfunktionellen Aziridine zum Vernetzen von Carboxylgruppen aufweisenden Polyacrylaten verwendet werden können (US-PS 42 78 578, Sp. 2, Z. 12-28). Aus diesem Stand der Technik ist zwar zu entnehmen, daß sowohl das genannte Polyurethan als auch das Carboxylgruppen aufweisende Polyacrylat jeweils für sich vernetzt werden können und daß die Mischung des dispergierten Polyurethans mit einem Acryllatex in einer unvernetzten Form zu Filmen mit günstigen Eigenschaften führt, jedoch konnte daraus nicht geschlossen werden, daß gerade die Mischung aus Carboxylgruppen enthaltendem Polyurethan und Carboxylgruppen enthaltendem Polyacrylat durch gemeinsame Vernetzung zu Produkten mit besonderen Verwendungseigenschaften führt und zwar zu Verwendungseigenschaften, die in der US-PS nicht einmal genannt sind, nämlich zur Grundierung von Kunststoffen.It is also known from US Pat. No. 4,278,578 that polyurethanes dispersed in water, which are ionic Contain groups that can be crosslinked with hardeners (aziridines). In addition, the dispersions mixed with acrylic, alkyd or vinyl latices. It is also pointed out in the US-PS that the polyfunctional aziridines are used for crosslinking polyacrylates containing carboxyl groups (US-PS 4,278,578, col. 2, lines 12-28). From this prior art it can be seen that both the polyurethane mentioned and the polyacrylate containing carboxyl groups are each crosslinked individually can be and that the mixture of the dispersed polyurethane with an acrylic latex in an uncrosslinked Form leads to films with favorable properties, but it could not be concluded from this that just the mixture of carboxyl-containing polyurethane and carboxyl-containing Polyacrylate through joint cross-linking to form products with special application properties leads to use properties that are not even mentioned in the US-PS, namely the primer of plastics.
Wie wenig das beanspruchte Verfahren durch die Lehre aus der US-PS nahegelegt wurde, ist auch daraus ersichtlich, daß in der US-PS zur Weiterentwicklung des dort genannten Standes der Technik nun eine Kombination verwendet wird, welche neben dem Härter (Aziridin) ein Carboxylgruppen aufweisendes Polyurethan, ein Carboxylgruppen aufweisendes Polyacrylat und als drittes Polymer einen mit einer monoäthylenivr? ungesättigten zweibasigen Säure modifizierten Ester eines Naturharzes oder ein Styrol-Maleinsäureanhydrid-Copolymerisat enthält Es wird also noch eine dritte Polymer-Komponente hinzugenommen, woraus an sich zu schließen ist daß mit der Mischung aus Polyurethan, Polyacrylat und Härter keine zufriedenstellenden Ergebnisse zu erhalten waren. Zudem wird auch die in der US-PS beanspruchte Zusammensetzung nicht zum Grundieren von Kunststoffen unter Verwendung eines Pigmentes, sondern zum Überziehen von Kunststoffen eingesetztHow little the claimed method was suggested by the teaching of the US patent is also therefrom It can be seen that in the US-PS for the further development of the prior art cited there now a combination is used, which in addition to the hardener (aziridine) is a carboxyl-containing polyurethane, a polyacrylate containing carboxyl groups and, as the third polymer, one with a monoäthylenivr? unsaturated dibasic acid-modified ester of a natural resin or a styrene-maleic anhydride copolymer It also contains a third polymer component, from which to itself The conclusion is that the mixture of polyurethane, polyacrylate and hardener does not give satisfactory results were to be obtained. In addition, the composition claimed in US Pat Priming of plastics using a pigment, but for coating plastics used
Aus dem Journal of Coated Fabrics, Vol. 3 (1974), S. 181 —193, insbesondere S. 186, ist es bekannt, daß einer
wäßrigen Dispersion von Carboxylgruppen enthaltendem Polyurethan ein Pigment und — als Verdikkungsmittel
— ein Polyacrylat zugesetzt werden können, wobei unterstellt werden kann, daß das Polyacrylat
für seine Funktion als Verdickungsmittel Carboxylgruppen aufweist. Da in dieser Literaturstelle ein Härter
nicht genannt ist und das Polyacrylat lediglich die Funktion eines Verdickungsmittels ausübt und somit auch
nur in entsprechend geringen Mengen vorhanden sein dürfte, konnte aus dieser Literaturstelle ebenfalls nicht
auf die gemeinsame Härtung von Polyurethan und Polyacrylat geschlossen werden und noch weniger auf die
Eignung einer wäßrigen Dispersion aus jewiels Carboxylgruppen enthaltendem Polyurethan und Polyacrylat
sowie Härter für das Grundieren von Kunststoffen, zumal dieser Verwendungszweck in der Literaturstelle gar
nicht genannt ist.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Grundieren von Kunststoffen zu schaffen,
bei dem einerseits der Kunststoff nicht angegriffen wird und daj andererseits umweltfreundlich istFrom the Journal of Coated Fabrics, Vol. 3 (1974), pp. 181-193, in particular p. 186, it is known that a pigment and - as a thickening agent - a polyacrylate can be added to an aqueous dispersion of polyurethane containing carboxyl groups, it can be assumed that the polyacrylate has carboxyl groups for its function as a thickener. Since a hardener is not mentioned in this reference and the polyacrylate only functions as a thickener and is therefore only likely to be present in correspondingly small quantities, this reference also did not allow conclusions to be drawn about the joint hardening of polyurethane and polyacrylate, and even less the suitability of an aqueous dispersion of polyurethane and polyacrylate each containing carboxyl groups as well as hardeners for priming plastics, especially since this purpose is not mentioned in the reference.
The invention is based on the object of creating a method for priming plastics in which, on the one hand, the plastic is not attacked and, on the other hand, is environmentally friendly
Diese Aufgabe wird erfindungsgemäß durch das im Anspruch 1 genannte Verfahren gelöst, wobei die Ausgestaltungen dieses Verfahrens in den Ansrüchen 2—7 beschrieben sind.According to the invention, this object is achieved by the method mentioned in claim 1, with the embodiments this method are described in claims 2-7.
Es wird somit eine pigment- und bindemittelhaltige Mischung zum Grundieren von Kunststoffen verwendet, deren Bindemittel durch in Wasser dispergiertes, aliphatisches Polyurethan und in Wasser dispergiertes Polyacrylat gekennzeichnet ist.A mixture containing pigments and binders is used to prime plastics, their binders by aliphatic polyurethane dispersed in water and dispersed in water Polyacrylate is marked.
Als Polyurethane und Polyacrylate kommen all jene Stoffe in Frage, die in Wasser dispergiert (als Dispersion oder Hydrosol) sind, obheralb von 00C filmbildende Eigenschaften aufweisen, pigmentverträglich und lagerstabil sind und die reaktionsfähige Carboxylgruppen enthalten. Ferner müssen beide Produkte scherkraftstabi! sein, um auf handelsüblichen Dispergiergeräten (z. B.As polyurethanes and polyacrylates those are suitable are dispersed in water (as a dispersion or hydrosol) obheralb film-forming from 0 0 C properties, are compatible and storage stable pigment and containing reactive carboxyl groups. Furthermore, both products must be shear-resistant! in order to be able to use commercially available dispersing devices (e.g.
Zur Herstellung der zu verwendenden Grundierungsmjttel werden Polyurethan-Dispersionen eingesetzt, die bei einem Festkörpergehalt (Gew.-%) von 25—50%, vorzugsweise 35—40%, eine Konsistenz von < 1000 mPas, vorzugsweise 100—500 mPas, aufweisen. Das Polyacrylat-Hydrosol hat bei einem Festkörperanteil in Gew.-% von 35—55%, vorzugsweise 45%, eine Konsistenz von < 400 mPas, vorzugsweise <200mPas.To produce the primers to be used, polyurethane dispersions are used which at a solids content (% by weight) of 25-50%, preferably 35-40%, a consistency of <1000 mPas, preferably 100-500 mPas. The polyacrylate hydrosol has a solids content in% by weight of 35-55%, preferably 45% Consistency of <400 mPas, preferably <200mPas.
In der srfindungsgemäß verwendeten Mischung be- ίο trägt der Festkörperanteil 35—70 Gew.-%, insbesondere 52-58 Gew.-%.In the mixture used according to the invention be ίο the solids content is 35-70% by weight, in particular 52-58% by weight.
Der Flüssigkeitsanteil braucht nicht nur aus Wasser zu bestehen, sondern er kann auch aus 75—99 Gew.-%, insbesondere 81—92Gew.-%, Wasser und 25—1 Gew.-%, insbesondere 19—8Gew.-%, organischen Lösungsmitteln und zugesetztem Neutralisationsmittel bestehen.The liquid part need not only consist of water, but it can also consist of 75-99% by weight, in particular 81-92% by weight, water and 25-1% by weight, in particular 19-8% by weight, organic solvents and added neutralizing agent.
Eine solche vollständig oder weitgehend von Lösungsmitteln organischer Art freie Dispersion greift den Kunststoff, der gradiert wird, nicht an. Hinzu kommt, daß die Dispersion keine Verunreinigung der Atmosphäre bewirken kann.Such a dispersion which is completely or largely free of solvents of an organic nature takes effect Plastic that is graded is not on. Come in addition, that the dispersion cannot cause pollution of the atmosphere.
Die Dispersion kann mit und ohne Härtungsbeschleuniger verwendet werden. Als Pigment können die sonst üblichen Pigmente eingesetzt werden.The dispersion can be used with or without a hardening accelerator. As a pigment they can otherwise customary pigments are used.
Die wäßrige Dispersion kann durch die üblichen Verfahren aufgetragen werden.The aqueous dispersion can be applied by the usual methods.
