Abstract

The car polish drying agent consists of 30 - 90% by weight of a quaternary ammonium compound of the formulae <IMAGE> in which R1 and R2 are C8-C20 alkyl or alkenyl, R3 and R4 are, identically or independently of one another, C1-C4-alkyl or hydroxyalkyl, n is 2 or 3 and X is an anion, and 15-70, preferably 15- 40, % by weight of a C8-C20 alkanol or alkenol or of a C8-C20-carboxylic acid C1-C4-alkyl ester.

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 dem Wasser oberflächenaktive quarternäre 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. When washing cars, 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 the formation of stains or streaks from the salts and other contaminants in the water. For this purpose, surface-active quaternary ammonium compounds are added to the water 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 auch bekannt, diese quarternären Ammoniumverbindungen als Dispersionen in Petroleum einzusetzen, da durch das Petroleum auch der Aufreißeffekt des Wasserfilms begünstigt wird. Bei diesen Formulierungen auf Basis Petroleum ist aber die Mitverwendung eines teuren Emulgators unerläßlich. Trotz Verwendung solcher Emulgatoren sind aber diese Konzentrate nicht sehr lagerstabil; häufig erfolgt nach Tagen oder Wochen eine Trennung der beiden Komponenten. Zudem ist die Verwendung von Petroleum an sich schon nach- teilig und lästig, da das Petroleum aus dem Waschwasser abgetrennt werden muß. Auf der anderen Seite ist die Wirkung der quarternären Ammoniumverbindungen allein zu schwach, so daß beim schnellen Durchschleusen der Autos durch die Waschanlage das Aufreißen des Wasserfilms unvollständig ist.It is also known to use these quaternary ammonium compounds as dispersions in petroleum, since the petroleum also promotes the tearing effect of the water film. These formulations are based on petroleum but the use of an expensive emulsifier is essential. Despite the use of such emulsifiers, however, these concentrates are not very stable in storage; the two components are often separated after days or weeks. In addition, the use of petroleum itself is disadvantageous and troublesome, since the petroleum has to be separated from the wash water. On the other hand, the effect of the quaternary ammonium compounds alone is too weak, so that when the cars are quickly passed through the car wash, the water film is incomplete.

Es wurde nun ein Autoglanztrocknungsmittel gefunden, das diese Nachteile nicht besitzt. Dieses Autoglanztrocknungsmittel besteht aus 30 - 90, vorzugsweise 60 - 70 Gew.-% einer quarternären Ammoniumverbindung der Formeln

Figure imgb0001
worin R1 und R2 C8-C20 Alkyl oder Alkenyl, R3 und R4 gleich oder unabhängig voneinander C1-C4-Alkyl oder Hydroxyalkyl, n 2 oder 3 und X ein Anion bedeutet und 15 - 70, vorzugsweise 15 - 40 Gew.-% eines C8-C20 Alkanols oder Alkenols oder eines C8-C20-Carbonsäure-C1-C4-alkylesters.An automobile gloss drying agent has now been found which does not have these disadvantages. This car gloss drying agent consists of 30-90, preferably 60-70% by weight of a quaternary ammonium compound of the formulas
Figure imgb0001
 wherein R 1 and R 2 are C8-C 20 alkyl or alkenyl, R 3 and R 4 are the same or independently of one another C 1 -C 4 alkyl or hydroxyalkyl, n 2 or 3 and X is an anion and 15-70, preferably 15- 40% by weight of a C 8 -C 20 alkanol or alkenol or a C 8 -C 20 carboxylic acid C 1 -C 4 alkyl ester.

Die erwähnten quarternären Ammoniumverbindungen enthalten in beiden Fällen Alkyl- oder Alkenylgruppen mit 8 - 20 C-Atomen, vorzugsweise 16 - 18 C-Atomen. Bevorzugt ist der Alkenylrest, der dem natürlichen Talgfett entspricht. Unter der Bedeutung von R3 und R4 sind Methylgruppen bevorzugt, sowie solche Verbindungen, bei denen R3 Hydroxypropyl und R4 Methyl ist. Als Anionen kommen Chlorid, Bromid, Jodid, Phosphat oder vorzugsweise Methosulfat in Frage. Von den Alkanolen wird ein Alkohol mit 14 - 20 C-Atomen und einer Jodzahl von 70-100 bevorzugt. Diese Alkanole bzw. Alkenole können ganz oder teilweise auch ersetzt werden durch den Ester aus einer C8-C20-Fettsäure und einem niederen Alkohol.In both cases, the quaternary ammonium compounds mentioned contain alkyl or alkenyl groups with 8-20 C atoms, preferably 16-18 C atoms. The alkenyl radical which corresponds to the natural tallow fat is preferred. Under the meaning of R 3 and R 4 , methyl groups are preferred, as are those compounds in which R 3 is hydroxypropyl and R 4 is methyl. Anions are chloride, bromide, iodide, phosphate or preferably methosulfate. An alcohol with 14 - 20 carbon atoms becomes of the alkanols and an iodine number of 70-100 is preferred. All or some of these alkanols or alkenols can also be replaced by the ester of a C 8 -C 20 fatty acid and a lower alcohol.

Für die Praxis werden diese Autoglanztrocknungsmittel in Form von Lösungen in Wasser und/oder Alkoholen durch einfaches Zusammenrühren der einzelnen Komponenten hergestellt, wobei kein Emulgator benötigt wird. Man stellt zunächst ein Konzentrat her, das 30 - 90, vorzugsweise 60 - 70 Gew.-% der oben beschriebenen quarternären Ammoniumverbindungen und 15 - 70, vorzugsweise 15 - 40 Gew.-% des beschriebenen Alkanols, Alkenols bzw. Esters enthält. Der Rest ist Wasser und/oder ein C1-C4-Alkohol. Dieses Konzentrat wird dann mit Wasser und niederen Alkoholen, wie etwa Isopropanol oder Butylglykol zu einem sogenannten Vorkonzentrat verdünnt, das ca. 10 - 20 Gew.-% des zuvor erwähnten Konzentrats enthält. Dieses Vorkonzentrat wird dann weiter mit Wasser 150-500fach, vorzugsweise 300fach verdünnt und in dieser Form als letztes Spülwasser in Autowaschanlagen auf die Wagenoberfläche aufgesprüht. Eine visuelle Beobachtung des so gewaschenen Fahrzeugs zeigt, daß nach dem Auftragen des erfindungsgemäßen Glanztrocknungsmittels das restliche Wasser schnell in Form von Tropfen abläuft bzw durch ein Gebläse weggeschleudert wird und die behandelte Wagenoberfläche ein glänzendes Aussehen besitzt.In practice, these car gloss drying agents are produced in the form of solutions in water and / or alcohols by simply stirring the individual components together, with no emulsifier being required. A concentrate is first prepared which contains 30-90, preferably 60-70% by weight of the quaternary ammonium compounds described above and 15-70, preferably 15-40% by weight of the alkanol, alkenol or ester described. The rest is water and / or a C 1 -C 4 alcohol. This concentrate is then diluted with water and lower alcohols, such as isopropanol or butyl glycol, to give a so-called preconcentrate, which contains about 10-20% by weight of the concentrate mentioned above. This preconcentrate is then further diluted with water 150-500 times, preferably 300 times, and sprayed onto the car surface in this form as the last rinse water in car washes. A visual observation of the vehicle washed in this way shows that after the application of the gloss drying agent according to the invention, the remaining water quickly runs off in the form of drops or is thrown away by a blower and the treated vehicle surface has a shiny appearance.

Das folgende Beispiel erläutert die Erfindung ohne sie zu beschränken.The following example illustrates the invention without restricting it.

Beispielexample

Ein Autoglanztrocknungsmittel wurde hergestellt durch Vermischen folgender Komponenten:

Figure imgb0002
A car gloss drier was made by mixing the following components:
Figure imgb0002

Dieses Konzentrat ist im Temperaturbereich zwischen -5°C und +50°C lagerstabil und neigt auch nach wochenlanger Lagerzeit unter den Bedingungen eines Schaukeltests (-5°C +50°C) nicht zu Trennungserscheinungen.This concentrate is stable in storage in the temperature range between -5 ° C and + 50 ° C and does not tend to show signs of separation even after weeks of storage under the conditions of a rocking test (-5 ° C + 50 ° C).

10 Gew.-Teile dieses Konzentrates werden weiter mit 20 Gew.-Teilen Isopropanol oder Butylglykol und 70 Gew.-Teilen Wasser verdünnt.10 parts by weight of this concentrate are further diluted with 20 parts by weight of isopropanol or butyl glycol and 70 parts by weight of water.

Von dieser Formulierung werden dann kontinuierlich 2-6 Gramm pro Liter Spülwasser einer Autoschnellwaschanlage zugesetzt. Das Waschverfahren umfaßt das Waschen der Autokarosserie, die Spülung mit frischem Wasser und eine anschließende zweite Spülung, der die vorstehend angegenene Formulierung zugesetzt wurde. Dann wurde zu Prüfungszwecken eine dritte Spülung aus frischem Wasser ohne Zusätze auf die Autokarosserie aufgespritzt, worauf diese trocken geblasen und das Ergebnis visuell beobachtet wurde. Dabei wurde festgestellt, daß das Spülwasser schneller abläuft und auf der Oberfläche der Autokarosserie ein GlanZ auftritt.From this formulation, 2-6 grams per liter of rinse water are then continuously added to a rapid car wash. The washing process involves washing the car body, rinsing with fresh water and then a second rinse to which the above formulation has been added. Then a third rinse of fresh water without additives was sprayed onto the car body for testing purposes, whereupon it was blown dry and the result was observed visually. It was found that the rinsing water runs off faster and a gloss appears on the surface of the car body.
