Definitions

  • Cationic surfactants suitable for formulations in drying agents for paint surfaces are described in detail in DE-OS 28 06 980 and 30 32 220 and in Polishing and waxing compositions, MG Halpern, Noyes Data Corporation, USA (1982), pp. 78-89).

Abstract

Readily biodegradable hydrocarbon-free drying agent, which can be diluted with water, for painted surfaces containing cationic surfactant, emulsifier, solvent and a specific oily component which is likewise biodegradable.

Description

Die Erfindung betrifft ein neues, leicht biologisch abbaubares Trocknungsmittel für Autowaschanlagen. Solche Mittel werden dem Wasser des letzten Spül­gangs in Autowaschanlagen in geringen Mengen zuge­geben. Die Wirkbestandteile wandern dabei aus dem Wasser auf die Lackoberfläche und bilden dadurch eine hydrophobierende Schicht, die den Wasserfilm aufreißen läßt, so daß ein Großteil des Wassers von allein abtropft.The invention relates to a new, easily biodegradable drying agent for car washes. Such agents are added to the water of the last rinse in car washes in small quantities. The active ingredients migrate from the water to the surface of the paint and thereby form a hydrophobizing layer that allows the water film to tear, so that a large part of the water drips off by itself.

Solche Trocknungsmittel, bzw. Hydrophobierungsmittel enthalten kationische Tenside und eine ölige Kom­ponente als Wirksubstanzen, sowie als Hilfsbestand­teile Emulgatoren und Lösungsvermittler. Emulgatoren und Lösungsvermittler werden benötigt, um aus den Wirksubstanzen ein einheitliches, wasserverdünnbares und dadurch in der Praxis verwendbares Produkt her­stellen zu können. Als Konservierungsmittel enthal­ten solche Produkte zusätzlich noch Wachse oder Si­licone, um eine längere Haltbarkeit dieser Hydro­phobierungsschicht zu bewirken.Such drying agents or water repellents contain cationic surfactants and an oily component as active substances, and as auxiliary components, emulsifiers and solubilizers. Emulsifiers and solubilizers are required in order to be able to produce a uniform, water-dilutable product that can be used in practice from the active substances. Such products also contain waxes or silicones as preservatives in order to ensure that this hydrophobic layer lasts longer.

Marktübliche Trocknungsmittel enthalten Kohlenwasser­stoffe, wie Alkylbenzole, Mineralöle oder Petroleum, als ölige Komponente und eventuell als Lösungsmittel. Diese zeigen zwar eine sehr gute Hydrophobierungswir­kung, sind aber im Wasser nur schwer abbaubar.Commercial drying agents contain hydrocarbons, such as alkylbenzenes, mineral oils or petroleum, as an oily component and possibly as a solvent. Although these show a very good hydrophobic effect, they are difficult to degrade in water.

Es wurde versucht, kohlenwasserstofffreie Trocknungs­mittel herzustellen. Ohne die ölige Komponente ist die Trocknungswirkung jedoch zu schlecht.Attempts have been made to produce hydrocarbon-free drying agents. Without the oily component, however, the drying effect is too poor.

In der DE-OS 34 27 726 wird die Verwendung eines spe­ziellen Acetals als ölige Komponente beschrieben. Diese Acetale lassen sich aber nicht mit den neueren, besonders leicht biologisch abbaubaren, kationischen Tensiden der Struktur (XIV) kombinieren, da sie nur im sauren Bereich (unter PH 6) ausreichend lagestabil sind und die Acetate nur im alkalischen Bereich sta­bil (Hans Bayer, Lehrbuch der org. Chemie, S. Hirzel Verlag, Stuttgart (1973) S. 178) sind.DE-OS 34 27 726 describes the use of a special acetal as an oily component. However, these acetals cannot be combined with the newer, particularly readily biodegradable, cationic surfactants of the structure (XIV), since they are only sufficiently stable in the acidic range (below PH 6) and the acetates are only stable in the alkaline range (Hans Bayer, Textbook of the org.Chemistry, S. Hirzel Verlag, Stuttgart (1973) p. 178).

In der DE-OS 28 06 980 werden C₈-C₂₀-Alkohole als ölige Komponente vorgeschlagen. Diese Art von koh­lenwasserstofffreiem Trockner zeigte in eigenen Ver­suchen kein zufriedenstellendes Ergebnis.In DE-OS 28 06 980 C₈-C₂₀ alcohols are proposed as an oily component. This type of hydrocarbon-free dryer has not shown a satisfactory result in its own experiments.

Es hat sich überraschender Weise herausgestellt, daß Substanzen der allgemeinen Formel R₁ - X - R₂ als ölige Komponente für Trocknungsmittel von Lack­oberflächen geeignet sind.It has surprisingly been found that substances of the general formula R₁ - X - R₂ are suitable as an oily component for drying agents on paint surfaces.

In der allgemeinen Formel sind R₁ und R₂ Alkyl- oder Alkenylreste mit 6 bis 18 Kohlenstoffatomen und X eine der Gruppierungen:

Figure imgb0001

 wobei R₃ ein Alkyl- oder Alkenylrest mit 1 bis 6 Koh­lenstoffatomen oder ein H-Rest ist und mit einem der Reste R₁ oder R₂ einen gemeinsamen Ring bilden kann, R₄ ein Alkylen- oder Alkenylenrest mit 1 bis 4 Kohlenstoff­atomen in der Kette ist oder auch ganz entfallen kann und R₅ ein Alkylen- oder Alkenylenrest mit 2 bis 4 Kohlenstoffatomen in der Kette oder ein Dialkylen­glykolrest ist.In the general formula, R₁ and R₂ are alkyl or alkenyl radicals having 6 to 18 carbon atoms and X is one of the groups:

 wherein R₃ is an alkyl or alkenyl radical with 1 to 6 carbon atoms or an H radical and can form a common ring with one of the radicals R₁ or R₂, R₄ is an alkylene or alkenylene radical with 1 to 4 carbon atoms in the chain or also entirely can be omitted and R₅ is an alkylene or alkenylene radical having 2 to 4 carbon atoms in the chain or a dialkylene glycol radical.
