Description

FeststoffzubereitungenSolid preparations
Gebiet der ErfindungField of the Invention
Die Erfindung betrifft feste, praktisch wasserfreie Zubereitungen mit einer ternären Tensidmischung und Elektrolytsalzen sowie die Verwendung dieser Mischungen zur Reinigung und antistatischen Ausrüstung von lackierten Metalloberflächen, insbesondere Karosserien und Karosserieteilen.The invention relates to solid, practically water-free preparations with a ternary surfactant mixture and electrolyte salts, and to the use of these mixtures for cleaning and antistatic finishing of painted metal surfaces, in particular bodies and body parts.
Stand der TechnikState of the art
In Zeiten gestiegenen ökologischen Bewußtseins verliert die Handwäsche von Kraftfahrzeugen auch für den privaten Fahrzeughalter an Bedeutung, da mit dem Eintrag von ölverschmutztem Abwasser in die Kanalisation eine erhebliche Kontamination der Umwelt verbunden ist. Im Gegenzug nimmt die Wäsche an speziellen Stationen zu, die entweder über abgeschlossene Systeme zum Auffangen des Waschwassers oder spezielle Olabscheider verfügen. Neben den sogenannten „Waschstraßen", bei denen die Fahrzeuge nacheinander beispielsweise über ein Kettentransportsystem an einer Abfolge von Wasch-, Bürsten- und Trockenstationen vorbeigeführt werden, erleben Selbstbedienungsanlagen besondere Konjunktur, bei denen die Kunden ihre Fahrzeuge mit einem Hochdruckwasserstrahl reinigen können, dem auf Wunsch ein Strom einer wäßrigen Waschmittelzubereitung zugeschaltet werden kann. In diesem Zusammenhang wurde jedoch festgestellt, daß lackierte Metalloberflächen, insbesondere solche, die weiße oder rote Farbstoff pigmente enthalten, die Tendenz zeigen, durch elektrostatische Aufladung Flugstaub anzuziehen und daher sehr rasch wieder zu verschmutzen.In times of increased ecological awareness, hand washing of motor vehicles is also becoming less important for the private vehicle owner, since the entry of oil-contaminated wastewater into the sewage system is associated with considerable environmental contamination. In return, the laundry increases at special stations, which either have closed systems for collecting the washing water or special oil separators. In addition to the so-called "car washes", in which the vehicles are successively guided past a sequence of washing, brushing and drying stations, for example via a chain transport system, self-service systems are experiencing a particular boom in which customers can clean their vehicles with a high-pressure water jet, if requested In this connection, however, it has been found that painted metal surfaces, in particular those which contain white or red dye pigments, have a tendency to attract fly dust by means of electrostatic charging and therefore to become dirty again very quickly.
Die Aufgabe der vorliegenden Erfindung hat folglich darin bestanden, feste Waschmittel zur Verfügung zu stellen, die sich auch in kaltem Wasser leicht lösen, ein ausgezeichnetes Reinigungsvermögen, vorzugsweise für Ölschmutz, aufweisen und gleichzeitig lackierten Metalloberflächen, insbesondere Karosserien und Karosserieteilen, eine antistatische Ausrüstung verleihen, die eine Wiederanschmutzung erschweren. Beschreibung der ErfindungThe object of the present invention was therefore to provide solid detergents which are easy to dissolve even in cold water, have excellent cleaning properties, preferably for oil soiling, and at the same time impart an antistatic finish to painted metal surfaces, in particular car bodies and body parts, which make it more difficult for them to be contaminated again.

Überraschenderweise wurde gefunden, daß sich die erfindungsgemäßen Zubereitungen auch bei niedrigen Temperaturen spontan und vollständig in Wasser auflösen und dann ein Reinigungsmittel ergeben, mit dessen Hilfe man beispielsweise Kraftfahrzeuge, aber auch andere lackierte Metalloberflächen, rasch und effektiv von Fett- und Olrückständen sowie weiteren Verschmutzungen reinigen kann. Gleichzeitig verleihen die Mittel den so behandelten Teilen eine antistatische Ausrüstung, die eine Wiederanschmutzung deutlich erschwert.Surprisingly, it has been found that the preparations according to the invention dissolve spontaneously and completely in water even at low temperatures and then give a cleaning agent with the aid of which, for example, motor vehicles, but also other painted metal surfaces, can be quickly and effectively cleaned of grease and oil residues and other contaminants can. At the same time, the agents give the parts treated in this way an antistatic finish, which makes it much more difficult for them to become dirty again.

The preparations can be prepared by known processes, ie in their simplest form powder mixtures with bulk densities in the range from 650 to 750 g / l are produced in a mixer, for example from the Schugi company. In principle, of course, the large-scale processes known for the production of washing powders can also be used, e.g. the drying of aqueous slurries with hot gases (spray drying) or superheated steam (steam drying) in countercurrent, agglomeration in the fluidized bed (SKET granulation) and the like. In addition to the ingredients mentioned, the preparations can also contain further surfactants, for example sulfosuccinates, sorbitan esters, polysorbates, ester quats or betaines, and saturated or unsaturated fatty acids, silicone oils and Guerbet alcohols.
Gewerbliche AnwendbarkeitIndustrial applicability
Die erfindungsgemäßen Mittel lösen sich auch in der Kälte leicht in Wasser, reinigen lackierte Metalloberflächen auch von hartnäckig anhaftenden Verschmutzungen und rüsten diese gegen Wiederanschmutzung antistatisch aus. Ein weiterer Gegenstand der Erfindung betrifft daher ihre Verwendung zur Herstellung von Waschmitteln für die gleichzeitige Reinigung und antistatische Ausrüstung von lackierten Metalloberflächen, insbesondere von Karosserien und Karosserieteilen. The agents according to the invention also dissolve easily in water in the cold, clean painted metal surfaces from stubbornly adhering soiling and provide them with an antistatic treatment against re-soiling. Another object of the invention therefore relates to their use for the production of detergents for the simultaneous cleaning and antistatic finishing of painted metal surfaces, in particular of bodies and body parts.
BeispieleExamples
Zur Bewertung der anwendungstechnischen Eigenschaften wurden die erfindungsgemäßen Zusammensetzungen 1 bis 3 sowie die Vergleichsmischungen V1 bis V3 hinsichtlich ihrer Reinigungsleistung, der antistatischen Ausrüstung und des Ablaufverhaltens beurteilt. Die Beurteilung des Reinigungsvermögens erfolgte dergestalt, daß ein rotlackiertes Blech (10 x 10 cm) mit 5 g Schmieröl bestrichen und dann 20 s mit einer 5 gew.-%igen wäßrigen Lösung der Testsubstanzen in Form eines scharfen Wasserstrahls („kärchern") behandelt wurde. Anschließend wurde der Rückstand verascht, ausgewogen und zur ursprünglich aufgetragenen Menge Öl ins Verhältnis gesetzt. Die antistatische Ausrüstung wurde an Hand rotlackierter Bleche über den Weg der Leitfähigkeit bestimmt. Je höher der gefundene Widerstand ist, um so besser ist die antistatische Aufladung und um so geringer ist die Tendenz durch Flugstaub wieder zu verschmutzen. Das Ablaufverhalten wurde subjektiv bestimmt. (+++) steht dabei für sehr rasches, (-) für langsames Ablaufen. Die Ergebnisse sind in Tabelle 1 zusammengefaßt.To evaluate the performance properties, the compositions 1 to 3 according to the invention and the comparative mixtures V1 to V3 were assessed with regard to their cleaning performance, the antistatic finish and the run-off behavior. The cleaning ability was assessed in such a way that a red-lacquered sheet (10 × 10 cm) was coated with 5 g of lubricating oil and then treated for 20 s with a 5% strength by weight aqueous solution of the test substances in the form of a sharp water jet (“kärchern”) The residue was then incinerated, weighed and compared to the amount of oil originally applied. The antistatic equipment was determined on the basis of the conductivity using red lacquered metal sheets. The higher the resistance found, the better the antistatic charge and so on The tendency to pollute again with flying dust is less, the running behavior was determined subjectively. (+++) stands for very fast, (-) for slow running. The results are summarized in Table 1.
