Abstract

Cleansing mixt. consisting of nitrobenzene (I) and paraffin oil: (II), pref. in (I):(II) ratio 13:1 to 15:1 (14:1) used in cleansing, care and formation of a layer protective against corrosion, discolouration and soiling of light metals, esp. Al, surface-treated by eloxal process. Used esp. as external frontages of houses and large window frames. Protective layer has no high affinity to dirt particles. Paraffin oil may be replaced by other oils having same props.

Description

Anwendung eines Reinigungsmittels und Reinigungsmittel zur Reinigung, Pflege und Ausbildung einer Schutzschicht gegen Korrosion, Verfärbung und Verschmutzung von nach dem Eloxal-Verfahren oberflächenveredelten Leichtmetallen, insbesondere Aluminium0 Die Erfindung betrifft ein Reinigungsmittel und seine Anwendung zur Reinigung, Pflege und Ausbildung einer Schutzschicht gegen Korrosion, Verfärbung und Verschmutzung von nach dem Eloxal-Verfahren oberflächenveredelten Leichtmetallen, insbesondere Aluminium. Using a detergent and detergent for cleaning, Maintenance and formation of a protective layer against corrosion, discoloration and soiling of light metals surface-refined by the anodizing process, in particular Aluminum0 The invention relates to a cleaning agent and its use for cleaning, Maintenance and formation of a protective layer against corrosion, discoloration and soiling of light metals surface-refined by the anodizing process, in particular Aluminum.

Für die Reinigung von nach dem Eloxal-Verfahren oberflächenveredelten Leichtmetallen, insbesondere Aluminium, sind zahlreiche Reinigungsmittel entwickelt worden, mit denen eine momentane Reinigung der Leichtmetallteile, wie z.B. Außenfassaden von Häusern, Rahmen großer Schaufensterscheiben od.dgl., erzielbar ist. Nachteilig ist jedoch bei diesen bekannten Reinigungsmitteln, daß im Laufe der Zeit die Oberflächenveredelung der Leichtmetalle angegriffen wird und daß zum anderen eine erhöhte Verschmutzung der Leichtmetallteile eintritt.For cleaning surfaces that have been finished using the anodising process Light metals, especially aluminum, are numerous cleaning supplies have been developed with which a momentary cleaning of the light metal parts, such as e.g. exterior facades of houses, frames of large shop windows or the like., achievable is. However, the disadvantage of these known cleaning agents is that in the course the time the surface finishing of the light metals is attacked and that for others lead to increased contamination of the light metal parts.

Aufgabe der Erfindung ist es demgegenüber ein Reinigungsmittel zu schaffen, das neben einer intensiven Reinigung von nach dem Eloxal-Verfahren oberflächenveredelten Leichtmetallen, insbesondere Aluminium, gleichzeitig eine Pflege und die Ausbildung einer Schutzschicht gegen Korrosion, Verfärbung und Verschmutsung ermöglicht, wobei die erzielte Schutzschicht keine große Affinität gegenüber Schmutzteilchen aufweisen soll@ Es hat sich überraschenderteise gezeigt, daß die vorangehend wiedergegebene Aufgabe durch ein Reinigungsmittel lösbar ist, das aus einer Mischung aus Nitrobenzol und Paraffinöl besteht. Besonders vorteilhaft hat sich hierbei eine Mischung gezeigt, die aus 13 bis 15 Teilen, insbesondere 14 Teilen, Nitrobennzol und einem Teil Paraffinöl besteht.In contrast, the object of the invention is to provide a cleaning agent create, in addition to an intensive cleaning of the anodized surfaces Light metals, especially aluminum, at the same time a care and training allows a protective layer against corrosion, discoloration and soiling, whereby the protective layer obtained does not have a great affinity for dirt particles should @ It has surprisingly been shown that the previously reproduced Task can be solved by a cleaning agent that consists of a mixture of nitrobenzene and paraffin oil. A mixture has proven to be particularly advantageous here, those from 13 to 15 parts, especially 14 parts, nitrobenzene and one part paraffin oil consists.

Die Erfindung besteht einerseits in dieser speziellen Ausbildung eines Reinigungsmittels und in der Anwendung eines au.e einer Mischung eines Nitrobenzols mit Paraffinöl bestehenden Reinigungsmittels zur Reinigung, Pflege und Ausbildung einer Schutzschicht gegen Eorrosion, Verfärbung und Verschmutzung von nach dem Eloxal-Verfahren oberflächenveredelten Leichtmetallen, insbesondere Aluminium, wobei die Mischung vorteilhafterweise aus 13 bis 15 Teilen, insbesondere 14 Teilen, Nitrobenzol und einem Teil Paraffinöl besteht.The invention consists on the one hand in this special training of a Cleaning agent and in the application of an au.e a mixture of a nitrobenzene with paraffin oil existing cleaning agent for cleaning, care and training a protective layer against erosion, discoloration and contamination by the anodizing process surface-finished light metals, especially aluminum, the mixture advantageously from 13 to 15 parts, in particular 14 parts, nitrobenzene and one part of paraffin oil.

Die erfindungsgemäße Mischung aus 13 bis 15 Teilen, insbesondere 14 Teilen Nitrobenzol und einem Teil Parrafinöl hat sich besonders wirkungsvoll als Reinigungsmittel für nach dem Eloxal-Verfahren oberflächenveredelten Leichtmetallen gezeigt Abweichungen von diesem Mischungsverhältnis führen bereits zu unbefriedigenden Ergebnissen. Ein höherer Anteil von Nitrobenzol führt zu einem sofortigen Antrocknen des Reinigungsmittels, , ohne daß eine Schutzschicht auf-dsn Leichtmetallen erzielt wird. Ein zu niedriger Anteil an Nitrobenzol führt dagegen zu einem zu starken Fettfilm auf den Leichtmetallen, wodurch die Gefahr einer erhöhten Verschmutzung gegeben ist. Anstelle von Paraffinöl können auGh andere gleichwertige und die Eigenschaften von Paraffinöl aufweisende Öle verwendet werdenO PatentansprücheThe mixture according to the invention of 13 to 15 parts, in particular 14 Dividing nitrobenzene and one part paraffin oil has proven to be particularly effective Cleaning agent for light metals that have been surface-refined using the anodising process Deviations from this mixing ratio shown lead to unsatisfactory Results. A higher proportion of nitrobenzene leads to immediate drying of the cleaning agent without creating a protective layer on light metals will. Too low a proportion of nitrobenzene, on the other hand, leads to an excessively thick film of grease on the light metals, which increases the risk of pollution is. Instead of paraffin oil, other equivalent properties can also be used of oils containing paraffin oil can be used
