Description
Die vorliegende Erfindung betrifft ein Abbeizmittel zum Abbeizen von Lacken und Dispersionsfarben, enthaltend 2-40% unpolare und 10.90% polare Lösemittel sowie ein - anorganische Strukturbildner, ausgewählt aus der Gruppe Bentonite, mikroni sierte Tone, Perlite oder feindisperse Kieselsäure und Paraffin oder Wachs enthalten des - Verdickungsmittel, wobei die unpolaren Lösemittel Benzolderivate oder aliphati sche und/oder naphtenische Kohlenwasserstoffe sind und die polaren Lösemittel aus chlorkohlenwasserstofffreien Lösemitteln, ausgewählt aus der Gruppe Ester, Ketone, Glykole, Alkohole, Glykolether oder Glykolester, bestehen.The present invention relates to a stripping agent for stripping paints and Dispersion paints containing 2-40% non-polar and 10.90% polar solvents as well an - inorganic structuring agent, selected from the group bentonite, microni Contained clays, perlite or finely dispersed silica and paraffin or wax des - thickener, the non-polar solvents benzene derivatives or aliphati are and / or naphthenic hydrocarbons and the polar solvents chlorinated hydrocarbon-free solvents, selected from the group of esters, ketones, Glycols, alcohols, glycol ethers or glycol esters exist.
Ein Abbeizmittel der gattungsgemäßen Art ist aus der DE-OS 32 39 016 bekannt.A paint stripper of the generic type is known from DE-OS 32 39 016.
In dieser Druckschrift ist angegeben, daß das Abbeizmittel als Verdickungsmittel auch Wachs enthält, wobei allgemein bekannt ist, daß in diesem Zusammenhang Pa raffin als gleichrangig mit Wachs anzusehen ist.In this document it is stated that the paint remover as a thickener also contains wax, it being generally known that in this context Pa can be regarded as refined with wax.
Bei dem bekannten Abbeizmittel ist der Paraffin- oder Wachsanteil in gelöster Form zugegeben. In the known paint remover, the paraffin or wax portion is in dissolved form admitted.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Abbeizmittel der gattungsgemäßen Art zu schaffen, welches insbesondere stabil ist und einen deutli chen Anteil newtonscher Viskosität aufweist.The present invention has for its object a paint remover Generic type to create, which is particularly stable and a clear Chen portion of Newtonian viscosity.
Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß dem Verdickungsmittel der Paraffin-Wachs-Anteil in Form einer Paraffin/Wachs-Disperson in Anteilen von 1 bis 25% zugegeben ist.To solve this problem, the invention proposes that the Thickening agent of the paraffin-wax portion in the form of a paraffin / wax disperson is added in proportions of 1 to 25%.
Durch den Zusatz von Paraffin/Wachs-Dispersionen erhält man eine starke, stabile Viskositätserhöhung, die insbesondere auch einen wesentlichen Teil an newtonscher Viskosität enthält.The addition of paraffin / wax dispersions gives a strong, stable Viscosity increase, which in particular also a substantial part of Newtonian Contains viscosity.
Das derart verdickte Lösungsmittel zeigt eine hohe Lagerstabilität, neigt nicht zur Trennung der einzelnen Bestandteile und bietet den Vorteil guter Applikationseigen schaften als Abbeizer und ein breites Spektrum an Fertigungseigenschaften, was die Zusammensetzung der Lösemittelgemische betrifft. The solvent thickened in this way shows a high storage stability and does not tend to Separation of the individual components and offers the advantage of good application properties as paint strippers and a wide range of manufacturing properties, which the Composition of the solvent mixtures concerns.
Es ist möglich, dem erfindungsgemäßen Abbeizmittel bis zu 1,5% Celluloseether zuzusetzen, wodurch die newtonsche Viskosität nochmals erhöht und damit die Verarbeitungs eigenschaften des Abbeizmittels verändert werden können.It is possible to use the paint remover according to the invention up to Add 1.5% cellulose ether, which makes Newtonian Viscosity increased again and thus the processing properties of the paint remover can be changed.
Die Abwaschbarkeit des Abbeizmittels kann verbessert wer den durch die zusätzliche Hinzufügung von 0,1 bis zu 3% eines anionischen, kationischen und/oder eines nichtiono genen Tensides.The washability of the paint remover can be improved due to the additional addition of 0.1 to 3% an anionic, cationic and / or a non-iono genes surfactants.
Außerdem kann eine Erhöhung der hydrophilen Eigenschaften des Abbeizmittels durch den Zusatz von bis zu 12% Wasser erreicht werden.It can also increase the hydrophilic properties of the paint remover by adding up to 12% water can be achieved.
