Description

Die vorliegende Erfindung betrifft ein stark hydrophobierend wirkendes, mit Wasser verdünnbares Autoglanztrocknungsmittel, das in sehr verdünnter Form in Wasch-und Spülflüssigkeiten bei Autowaschanlagen verwendet wird. Bei der Autowäsche bildet sich durch die Anwendung von oberflächenaktiven Mitteln im Waschwasser auf der Fahrzeugoberfläche ein geschlossener, festhaftender Wasserfilm aus. Dieser Film muß entfernt werden, um die Bildung von Flecken oder Streifen durch die Salze und sonstigen Verunreinigungen des Wassers zu vermeiden. Zu diesem Zweck werden im Nachspülgang wasseroberflächenaktive quaternäre Ammoniumverbindungen zugesetzt. Durch die Absorption des kationischen Tensids an der Lackoberfläche reißt der Wasserfilm auf und das Wasser setzt sich in Form von Tropfen an der Lackoberfläche ab. Die Wassertropfen lassen sich dann leicht durch ein Gebläse entfernen.The present invention relates to a highly hydrophobic, water-dilutable car gloss drying agent which is used in very dilute form in washing and rinsing liquids in car washes. In the car wash, a closed, firmly adhering water film forms on the vehicle surface through the use of surface-active agents in the wash water. This film must be removed to avoid stains or streaks from the salts and other contaminants in the water. For this purpose, water-surface-active quaternary ammonium compounds are added in the rinse cycle. Due to the absorption of the cationic surfactant on the surface of the paint, the water film tears open and the water settles on the surface of the paint in the form of drops. The water drops can then be easily removed by a blower.

Es ist bekannt, daß zum Aufreißen des geschlossenen Wasserfilms im Nachspülgang dem Wasser oberflächenaktive quarternäre Ammoniumverbindungen zugestzt werden. Durch die Adsorption des kationischen Tensids an der Lackoberfläche reißt der Wasserfilm auf und das Wasser setzt sich tropfenförmig auf der Lackoberfläche ab. Weiterhin ist bekannt, daß durch Einsatz von Petroleum der Aufreißeffekt des Wasserfilms begünstigt wird. Die üblich verwendeten quartären Ammoniumverbindungen werden in Form von Chloriden in Formulierungen eingesetzt. Sie zeigen den Nachteil, daß solche Verbindungstypen gegen Eisen und Stähle korrosiv wirken, denn über kurze Zeit neigen Waschanlagen sowie auch ältere Automobile dazu, durch Korrosion Roststellen aufzuweisen. Autoglanztrocknungsmittel mit einem Gehalt an quartären Ammoniumverbindungen sind auch in der DE-OS 28 06 980 beschrieben.It is known that surface-active quaternary ammonium compounds are added to the water to rip open the closed water film in the rinse cycle. As a result of the adsorption of the cationic surfactant on the surface of the paint, the water film tears open and the water deposits on the surface of the paint in drops. It is also known that the tearing effect of the water film is promoted by the use of petroleum. The commonly used quaternary ammonium compounds are used in the form of chlorides in formulations. They show the disadvantage that such connection types have a corrosive effect on iron and steel, because for a short time washing systems and also older automobiles tend to show rust spots due to corrosion. Car gloss drying agents containing quaternary ammonium compounds are also described in DE-OS 28 06 980.

Überraschender Weise wurde gefunden, daß das in folgenden beschriebene Glanztrocknungsmittel diese erwähnten Nachteile nicht besitzt. Die erfindungsgemäßen neuen hydrophob wirkenden Glanztrocknungsmittelrohstoffe bestehen aus einer quartären Ammoniumverbindung, die als Anion ein nicht korrosiv wirkendes Anion enthält. Im besonderen Maße geeignet sind hier organische Anionen wie zum Beispiel Benzoat, Propionat.It has surprisingly been found that the gloss drying agent described below does not have these disadvantages mentioned. The new hydrophobic gloss drying agent raw materials according to the invention consist of a quaternary ammonium compound which contains an anion which is a non-corrosive anion. Organic anions such as benzoate and propionate are particularly suitable here.

Gegenstand der Erfindung ist ein Autoglanztrocknungsmittel, das im wesentlichen besteht aus 5 bis 90, vorzugsweise 8 bis 80 Gew.-% einer Verbindung der Formel I

worin a 1 oder 2, X eine Zahl von 1 bis 20, vorzugsweise 3 bis 5, y und z jeweils Zahlen von 2 bis 20, vorzugsweise 2 bedeuten und R und R1 die oben angegebenen Bedeutungen haben, und der an 100 Gew.- % fehlende Rest ist Wasser oder ein organisches Lösemittel.The invention relates to a car gloss drying agent which consists essentially of 5 to 90, preferably 8 to 80 wt .-% of a compound of formula I.
Figure imgb0001
 wherein R, and R 2 Ce-C 22 alkyl or Ce-C 22 alkenyl, R 3 C 1 -C 4 alkyl, R hydrogen or Ci-C 4 alkyl, n is a number from 1 to 20, and A is a benzoate or propionate anion, 5 to 70, preferably 8 to 50% by weight of a nonionic emulsifier of the formulas
Figure imgb0002
 wherein a 1 or 2, X is a number from 1 to 20, preferably 3 to 5, y and z are each numbers from 2 to 20, preferably 2 and R and R 1 have the meanings given above, and the amount of 100% by weight % missing rest is water or an organic solvent.

Bei den oben angegebenen Formeln enthalten die Gruppen R1 und R2 vorzugsweise 16 bis 18 C-Atome. Besonders bevorzugt ist hierbei der Alkylrest, der sich vom natürlichen Talgfett ableitet. Bei den C1-C4-Alkylgruppen unter den Bedeutungen von R und R3 ist Methyl bevorzugt. Das in dem erfindungsgemäßen Autoglanztrocknungsmittel enthaltene Wasser kann ganz oder teilweise durch organische Lösemittel ersetzt werden, wie beispielsweise Petroleum oder niedere Alkohole, etwa Isopropanol.In the formulas given above, the groups R 1 and R 2 preferably contain 16 to 18 carbon atoms. The alkyl radical derived from natural tallow fat is particularly preferred. In the case of the C 1 -C 4 alkyl groups under the meanings of R and R 3 , methyl is preferred. All or part of the water contained in the car gloss drying agent according to the invention can be replaced by organic solvents, such as, for example, petroleum or lower alcohols, for example isopropanol.

Für die Praxis werden diese Autoglanztrocknungsmittel durch einfaches Mischen der einzelnen Komponenten hergestellt. Mit den oben angegebenen Mengenverhältnissen erhält man dann ein Konzentrat, das weiter mit Wasser 150 bis 500 fach, vorzugsweise 300 fach verdünnt und in dieser Form als letztes Spülwasser in Autowaschanlagen auf die Wagenoberfläche aufgesprüht wird.In practice, these car gloss drying agents are produced by simply mixing the individual components. With the proportions given above, a concentrate is then obtained, which is further diluted 150 to 500 times, preferably 300 times with water and sprayed onto the car surface in this form as the last rinse water in car washes.

Eine visuelle Beobachtung der gewaschenen Fahrzeuge zeigt, daß nach dem Auftragen des erfindungsgemäßen Glanztrocknungsmittels der Wasserfilm innerhalb von 15 Sekunden aufreißt und das restliche Wasser schnell in Form von Tropfen abläuft bzw. durch Einsatz von Gebläsen weggeschleudert wird. Danach ist die Wagenoberfläche trocken, glänzend und fleckenfrei. Als besonderer Vorteil der beschriebenen Autoglanztrocknungsmittel ist zu erwähnen, daß diese Mittel eine deutlich verminderte korrodierende Wirkung zeigen. Dies ist insbesondere für die Waschanlagen selbst von Interesse, wo auch bei längerfristigem Einstaz dieser Autoglanztrocknungsmittel eine Korrosion vermieden wird.A visual observation of the washed vehicles shows that after application of the gloss drying agent according to the invention the water film tears open within 15 seconds and the remaining water quickly runs off in the form of drops or is blown away by the use of fans. After that, the car surface is dry, shiny and free of stains. A particular advantage of the car gloss drying agents described is that these agents have a significantly reduced corrosive effect. This is of particular interest for the car washes themselves, where corrosion is avoided even when these car gloss drying agents are used for a long time.

Vor dieser Formulierung werden kontinuierlich 2-6 g/1 dem Spülwasser einer Autoschnellwaschanlage zugesetzt. Das Waschverfahren unfaßt das Waschen der Autokarosserie und die Spülung, der die vorstehend angegebene Formulierung zugesetzt wurde. Dann wurde zu Prüfungszwecken eine dritte Spülung aus frischem Wasser ohne Zusätze auf die Autokarosserie aufgespritzt, trockengeblasen und das Ergebnis visuell beobachtet. Dabei wurde festgestellt, daß beim Einsatz der Formulierung nach Beispiel 1 das Spülwasser schneller abläuft und auf der Oberfläche der Autokarosserie ein Glanz auftritt.Before this formulation, 2-6 g / 1 are continuously added to the rinse water of a rapid car wash. The washing process includes washing the car body and rinsing to which the above formulation has been added. Then, for testing purposes, a third rinse of fresh water without additives was sprayed onto the car body, blown dry, and the result was observed visually. It was found that when using the formulation according to Example 1, the rinsing water runs off more quickly and a gloss appears on the surface of the car body.

Ersetzt man in der oben angegebenen Formulierung das Di-Talgfettalkylmethyloxethylammonium-Benzoat durch das Di-Talgfettalkyldimethylammoniumchlorid so zeigen sich in dem erwähnten Filterpapiertest nach einer Einwirkzeit von 2 Stunden deutliche Rostspuren an den Graugußspänen.If the di-tallow fatty alkylmethyloxethylammonium benzoate in the formulation given above is replaced by the di-tallow fatty alkyldimethylammonium chloride, the filter paper test mentioned clearly shows rust marks on the gray cast iron chips after an exposure time of 2 hours.

Bei der Verwendung zur Spülung eines gewaschenen Automobiles wurden hier die gleichen Beobachtungen wie in Beispiel 1 gemacht.
Figure imgb0004
 When used to flush a washed automobile, the same observations as in Example 1 were made here.

Die erfindungsgemäßen Formulierungen enthalten billige Bestandteile, besitzen ein gutes Lagerungsvermögen, und dienen bei der Auftragung auf Automobilkarosserien als schützender Glanzüberzug. Die verdünnte Form (2-6 g/I Wasser) in der sie verwendet werden können, macht sie äußerst wirtschaftlich. 25 kg des erfindungsgemäßen Glanzmittels reichen aus, um ungefähr 1000 - 3000 Automobilen einen gleichmäßigen Glanz zu erteilen.The formulations according to the invention contain inexpensive components, have good storage properties and serve as a protective gloss coating when applied to automobile bodies. The diluted form (2-6 g / l water) in which they can be used makes them extremely economical. 25 kg of the gloss agent according to the invention are sufficient to give a uniform gloss to approximately 1000-3000 automobiles.

Die aus dem Glanztrocknungsmittel hergestellten 10-20 %igen wasserlöslichen Formulierungen sind wegen ihrer niedrigen Viskosität und guten Mischbarkeit mit Wasser leicht zu verdünnen, wobei die Formulierung mittels einer Dosierpumpe dem Spülwasser direkt zugesetzt werden kann.The 10-20% water-soluble formulations produced from the gloss drying agent are easy to dilute because of their low viscosity and good miscibility with water, the formulation being able to be added directly to the rinsing water by means of a metering pump.
