Description

Die Erfindung betrifft ein Reinigungsmittel für harte Oberflächen, das insbesondere zur Reinigung der Außenflächen von Fahrzeugen in Waschanlagen eingesetzt werden kann. Es ist besonders geeignet zur lackschonenden Reinigung der Fahrzeugoberflächen, da auf den Einsatz mechanischer Reinigungshilfen wie beispielsweise Bürsten verzichtet werden kann. Der Reinigungseffekt beruht teilweise darauf, daß das Reinigungsmittel Zellulosefasern, enthält. An diese binden sich Schmutz- und Staubpartikel auf der Außenfläche der Fahrzeuge und werden so beim Abspülen des Reinigungsmittels mit Wasser schonend entfernt, ohne daß Kratzer im Lack entstehen.The invention relates to a cleaning agent for hard surfaces, in particular used to clean the outside surfaces of vehicles in car washes can be. It is particularly suitable for cleaning the paintwork gently Vehicle surfaces because of the use of mechanical cleaning aids such as for example brushing can be dispensed with. The cleaning effect is based partly because the detergent contains cellulose fibers, contains. Dirt and dust particles bind to these on the outer surface of the Vehicles and so when washing the detergent with water gently removed without scratching the paint.

Heutzutage ist es üblich, Fahrzeuge wie beispielsweise Personenkraftwagen, Lieferund Lastwagen, Busse oder Schienenfahrzeuge in automatischen Waschanlagen zu reinigen. Häufig sind diese Waschanlagen mit mechanischen Reinigungshilfen ausgestattet, die sich über die in der Regel lackierte Fahrzeugoberfläche bewegen und hierdurch Schmutz- und Staubpartikel abstreifen. Solche mechanischen Reinigungshilfen sind beispielsweise rotierende Bürsten oder sich bewegende Textil-, Kunststoff- oder Gummibänder oder -lappen. Beim mechanischen Abstreifen von Schmutz- und Staubpartikeln durch solche Reinigungshilfen läßt es sich kaum vermeiden, daß die oft sehr harten Partikel über den Lack streifen und hierbei zu Kratzern im Lack führen. Bei Verwendung konventioneller Reinigungsmittel sind solche mechanischen Reinigungshilfen jedoch in der Regel notwendig, da ohne deren Mithilfe Schmutz und Staub von den Fahrzeugoberlfächen im allgemeinen nicht befriedigend entfernt werden.Nowadays it is common to use vehicles such as passenger cars, delivery and Trucks, buses or rail vehicles in automatic car washes too clean. These washing systems are often equipped with mechanical cleaning aids equipped, which move over the usually painted vehicle surface and thereby wipe off dirt and dust particles. Such mechanical Cleaning aids are, for example, rotating brushes or moving ones Textile, plastic or rubber bands or rags. In the mechanical Dirt and dust particles can be wiped off by such cleaning aids can hardly avoid that the often very hard particles brush over the paint and lead to scratches in the paint. When using conventional However, such mechanical cleaning aids are usually cleaning agents necessary because without their help dirt and dust from the Vehicle surfaces are generally not removed satisfactorily.

Daher besteht ein Bedarf an Reinigungsmitteln und Reinigungsverfahren, die Schmutz- und Staubpartikel von Oberflächen entfernen können, ohne daß Kratzer im Lack entstehen. Die WO 94/19441 offenbart ein Reinigungsmittel, das vorzugsweise in Form eines Schaums auf die zu reinigende Oberfläche aufgebracht und anschließend ohne mechanische Hilfe mit Wasser abgespült wird. Hierdurch wird die Kratzerbildung deutlich reduziert. Als essentielle Komponente enthält das Reinigungsmittel ein wasserlösliches Zellulosederivat. Es wird unmittelbar vor der Anwendung mit einer zweiten alkalischen Reinigungskomponente vereinigt und auf die Oberfläche aufgesprüht. Fakultativ kann die vereinigte Reinigungsmischung zusätzlich Fasern wie beispielsweise Zellulosefasern enthalten. In einer bevorzugten Ausführungsform wird jedoch nach dem Aufbringen des faserfreien Reinigungsmittels auf die Oberfläche zusätzlich eine Fasersuspension auf die Oberfläche aufgesprüht. Dieses Verfahren hat zum einen den Nachteil, daß neben den üblichen reinigungsaktiven Komponenten ein wasserlösliches Zellulosederivat bereitgestellt werden muß. Dessen Herstellung ist energieaufwendig, ggf. umweltbelastend und erhöht die Kosten des Reinigungsmittels. Weiterhin ist das Reinigungsverfahren apparativ aufwendig, da mindestens 2, bei getrenntem Einsatz einer Fasersuspension mindestens 3 Produktbehältnisse bereitgestellt werden müssen. Weiterhin sind Leitungen und Dosiereinrichtungen erforderlich, um die einzelnen Komponenten vor der Applikation zu mischen bzw. nacheinander auf die Fahrzeugflächen aufzubringen.Therefore, there is a need for cleaning agents and cleaning processes that Can remove dirt and dust particles from surfaces without scratching arise in the paint. WO 94/19441 discloses a cleaning agent which preferably applied in the form of a foam to the surface to be cleaned and then rinsed with water without mechanical help. hereby scratch formation is significantly reduced. This contains as an essential component Detergent a water-soluble cellulose derivative. It is immediately before Application combined with a second alkaline cleaning component and on sprayed on the surface. Optionally, the combined cleaning mixture additionally contain fibers such as cellulose fibers. In a preferred one Embodiment, however, is applied after the application of the fiber free Detergent on the surface additionally a fiber suspension on the Sprayed surface. On the one hand, this method has the disadvantage that in addition to the usual active cleaning components a water-soluble cellulose derivative must be provided. Its production is energy-intensive, possibly polluting and increases the cost of the cleaning agent. Furthermore, that is Cleaning procedures are expensive, since at least 2, when used separately at least 3 product containers are provided for a fiber suspension have to. Furthermore, lines and dosing devices are required to Mix individual components before application or apply them one after the other Apply vehicle surfaces.

  • a) 0.1 to 20% by weight of chemically modified or unmodified vegetable cellulose fibers with a length of between 0.5 and 5 mm,
  • b) 0.05 to 5% by weight of thickener,
  • c) if necessary, so much alkalizing agent that the pH is in the range from 7 to 14,
    • for cleaning the outer surfaces of vehicles, characterized in that the cleaning agent is diluted with water in a ratio of 1: 1000 to 1: 6, the mixture thus obtained is sprayed onto the outer surfaces of vehicles at a pressure between 1 and 100 bar and after an exposure time in the Rinse area with water for 5 seconds and 5 minutes.

    Als Alkalisierungsmittel c) kommen beispielsweise Alkalimetallhydroxide, -carbonate, -phosphate und/oder -silicate in Betracht. Vorzugsweise liegt der pH-Wert im Bereich von 8 bis 11.Alkalizing agents c) include, for example, alkali metal hydroxides and carbonates, phosphates and / or silicates into consideration. The pH is preferably in the Range from 8 to 11.

    Das Verdickungsmittel b) stabilisiert die Fasersuspension und verzögert bzw. verhindert das Absetzen der Fasern. Beispielsweise sind Verdickungsmittel auf Acrylatbasis geeignet. Vorzugsweise wird als Verdickungsmittel jedoch Xanthangummi eingesetzt. Xanthangummi ist ein wasserlösliches Polymer auf Basis eines Polysaccharids. Die bevorzugte Konzentration des Verdickungsmittels liegt im Bereich von 0,1 bis 1 Gew.-%.The thickener b) stabilizes the fiber suspension and delays or prevents the fibers from settling. For example, thickeners are on Suitable acrylic base. Preferably, however, as a thickener Xanthan gum used. Xanthan gum is a water-soluble polymer Base of a polysaccharide. The preferred concentration of the thickener is in the range of 0.1 to 1% by weight.

    Das Reinigungsmittel kann zusätzlich etwa 0,01 bis etwa 5 Gew.-% nichtionische Tenside enthalten. Vorzugsweise weist es einen Tensidgehalt im Bereich von 0,5 bis 2 Gew.-% auf. Die Art des nichtionischen Tensids ist nicht kritisch. Aus Umweltgründen wählt man vorzugsweise solche nichtionischen Tenside, die biologisch abbaubar sind. Alkoxylate von Fettalkoholen sind bevorzugt. Beispielsweise können die Tenside ausgewählt werden aus Ethoxylaten, Propoxylaten und Ethoxylaten/Propoxylaten von Alkoholen mit einer Kettenlänge von 9 bis 14 Kohlenstoffatomen im Alkohol mit mindestens 2 Alkoxylateinheiten. Die Obergrenze der Ethoxylat- und/oder Propoxylateinheiten liegt bei 20.The detergent can additionally be about 0.01 to about 5% by weight nonionic Contain surfactants. It preferably has a surfactant content in the range of 0.5 up to 2% by weight. The type of nonionic surfactant is not critical. Out For environmental reasons, preference is given to choosing those nonionic surfactants which are biodegradable. Alkoxylates of fatty alcohols are preferred. For example, the surfactants can be selected from ethoxylates, Propoxylates and ethoxylates / propoxylates of alcohols with a chain length of 9 to 14 carbon atoms in alcohol with at least 2 alkoxylate units. The upper limit of the ethoxylate and / or propoxylate units is 20.

    Für längere Lagerzeiten ist es vorzuziehen, daß das Reinigungsmittel zusätzlich 0,01 bis 1 Gew.-%, insbesondere 0,02 bis 0,1 Gew.-% eines Konservierungsmittels enthält. Die Auswahl des Konservierungsmittels ist nicht kritisch, muß sich jedoch nach der lokalen Gesetzgebung richten. Als Konservierungsmittel sind beispielsweise Parabene oder die sogenannten "Kathontypen" wie beispielsweise Methylchloroisothiazolinon oder Methylisothiazolinon geeignet.For longer storage times, it is preferable that the cleaning agent additionally contains 0.01 to 1% by weight, in particular 0.02 to 0.1% by weight, of a preservative. The choice of preservative is not critical, but must be done according to local legislation. Suitable preservatives are, for example, parabens or the so-called " cathode types" such as methylchloroisothiazolinone or methylisothiazolinone.

    Die Zellulosefasern a) können beispielsweise in Form von Holz-, Zellstoff-, Baumwolle- oder Papierbrei vorliegen. Derartige Breie werden im angelsächsichen Sprachgebrauch als "pulp" bezeichnet. Im weiteren wird für derartige Aufschlußbreie pflanzlicher Zellulosefasern der Ausdruck "Pulpe" gebraucht. Die aus ggf. modifizierten pflanzlichen Zellulosefasern und Wasser bestehende Pulpe kann beispielsweise zermahlenes Holz, halbchemische Pulpe, Sulfit- oder Sulfatpulpe, die aus einem chemischen Holzaufschluß hervorgehen, sowie thermomechanische Pulpe darstellen. Die Verwendung der Fasern einer thermomechanischen Pulpe ist besonders bevorzugt, da diese auf einfache und ökonomische Weise erhältlich ist. Sie besteht aus einer Holzfaserdispersion und ist dadurch erhältlich, daß Holz in kleine Stücke geschnitten wird und diese in Wasser bei hohen Temperaturen aufgeschlossen werden.The cellulose fibers a) can, for example, be in the form of wood, cellulose, cotton or paper pulp. Such slurries are called " pulp" in Anglo-Saxon usage. The term "pulp" is used below for such pulping of vegetable cellulose fibers. The pulp, which may consist of modified vegetable cellulose fibers and water, can represent, for example, ground wood, semi-chemical pulp, sulfite or sulfate pulp which result from chemical wood pulping, and thermomechanical pulp. The use of the fibers of a thermomechanical pulp is particularly preferred since it can be obtained in a simple and economical way. It consists of a wood fiber dispersion and is obtainable by cutting wood into small pieces and digesting them in water at high temperatures.

    Vorzugsweise haben die Fasern eine Lände im Bereich von 1,5 bis 3 mm und insbesondere zwischen 2 und 2,5 mm. Der Anteil der Fasern in dem Reinigungsmittel liegt vorzugsweise im Bereich von 2 bis 10 Gew.%.The fibers preferably have a length in the range from 1.5 to 3 mm and in particular between 2 and 2.5 mm. The proportion of fibers in the Detergent is preferably in the range of 2 to 10% by weight.

    Das Reinigungsmittel kann vor oder nach dem Verdünnen mit Wasser mit weiteren Reinigungskomponenten versetzt werden. The detergent can be before or after the dilution with water can be mixed with other cleaning components.

    Beispiele derartiger zusätzlicher Reinigungskomponenten sind Komplexbildner, weitere nichtionische, ggf. auch anionische, zwitterionische oder kationische Tenside, zusätzliche Builderkomponenten wie beispielsweise Alkalimetallcarbonate, -borate, -phosphate oder -silicate, Carbonsäuren oder Carbonsäureanionen mit Kettenlängen im Bereich von 6 bis 12 Kohlenstoffatomen sowie Alkanolamine. Die anwendungsfertige wasserverdünnte Zubereitung des Reinigungsmittels, die ggf. die vorstehend beschriebenen weiteren Reinigungskomponenten enthalten kann, stellt man vorzugsweise auf einen pH-Wert im Bereich von 8 bis 11 ein, erforderlichenfalls mit Alkalimetallhydroxiden. Die Verwendung wasserlöslicher Zellulosederivate gemäß der Lehre der WO 94/19441 ist für die erfindungsgemäße Verwendung nicht erforderlich. Aus ökonomischen Gründen verzichtet man vorzugsweise auf diese Komponente.Examples of such additional cleaning components are complexing agents, further nonionic, possibly also anionic, zwitterionic or cationic Surfactants, additional builder components such as alkali metal carbonates, borates, phosphates or silicates, carboxylic acids or Carboxylic anions with chain lengths in the range of 6 to 12 carbon atoms as well as alkanolamines. The ready-to-use water-diluted preparation of the Detergent, if necessary, the others described above Can contain cleaning components, preferably set to a pH in the range of 8 to 11, if necessary with alkali metal hydroxides. The use of water-soluble cellulose derivatives according to the teaching WO 94/19441 is not required for the use according to the invention. Out For economic reasons, this component is preferably dispensed with.

    Vorzugsweise verwendet man das mit Wasser verdünnte Reinigungsmittel in Waschanlagen für Fahrzeuge, wobei keine mechanischen Reinigungshilfen eingesetzt werden. Bei den Waschanlagen für Fahrzeuge kann es sich um Waschanlagen für Personenkraftwagen, Liefer- und Lastwagen, Busse oder Schienenfahrzeuge handeln. Dadurch, daß auf mechanische Reinigungshilfen wie beispielsweise rotierende Bürsten oder bewegte Textil-, Kunststoff- oder Gummilappen verzichtet wird, wird die Gefahr eines Verkratzens lackierter Oberflächen deutlich vermindert.It is preferred to use the one diluted with water Detergents in car washes, no mechanical Cleaning aids are used. With car washes, it can are washing systems for cars, vans and trucks, buses or Trade rail vehicles. The fact that mechanical cleaning aids such for example rotating brushes or moving textile, plastic or If rubber rags are dispensed with, the risk of scratching is painted Surfaces significantly reduced.

    Die Verwendung des Reinigungsmittels hat also den unmittelbaren Vorteil, daß lackierte Oberflächen wesentlich mehr geschont werden als bei der konventionellen Verwendung von Reinigungsmitteln in Verbindung mit mechanischen Reinigungshilfen. Das Reinigungsmittel kann als Einkomponentensystem zur Verfügung gestellt werden, so daß es mit geringem apparativen Aufwand eingesetzt werden kann. Ein zusätzlicher Nebeneffekt der Verwendung pflanzlicher Zellulosefasern liegt darin, daß diese Schwermetallionen binden können. Bei einer anschließenden Wasserbehandlung, bei der die Fasern zusammen mit unlöslichem Schmutz als Schlamm abgetrennt werden, werden Schwermetalle vornehmlich im Schlamm immobilisiert. Die in eine biologische Kläranlage abzugebende Wasserphase ist dadurch deutlich weniger mit Schwermetallionen belastet als bei Reinigungsmitteln, die keine pflanzlichen Zellulosefasern verwenden.So the use of the detergent has immediate advantage that painted surfaces are protected much more than with the conventional use of detergents in connection with mechanical cleaning aids. The cleaning agent can be used as a one-component system be made available so that it can be operated with little equipment Effort can be used. An additional side effect of use Vegetable cellulose fibers lie in the fact that they bind heavy metal ions can. In a subsequent water treatment in which the fibers are together separated with insoluble dirt as sludge, become heavy metals mainly immobilized in the mud. The in a biological sewage treatment plant the water phase to be released is therefore significantly less with heavy metal ions contaminated than with detergents that do not contain vegetable cellulose fibers use.
