Abstract

Compsns. referred to as lubricant or care agents, esp. useful for care (cleaning and protection) of rubber, contain synthetic ester oils and natural oils.

Description

Die Erfindung betrifft Gleit- oder Pflegemittel aus mindestens einem synthetischen Esteröl und mindestens einem nativen Öl sowie die Verwendung eines solchen Gleit- oder Pflegemittels als Gummipflegemittel.The invention relates to lubricants or care agents made from at least one synthetic Ester oil and at least one native oil and the use of such Lubricants or care products as rubber care products.

Herkömmliche Gummipflegemittel sind auf Basis von Benzinkohlenwasserstoffen, wie Leicht- oder Testbenzin kombiniert mit mineralölstämmigen Fraktionen aufgebaut. Bekannt ist auch die Verwendung wässeriger Öl-, Silicon- oder Wachsemulsionen als Gummipflegemittel.Conventional rubber care products are based on petrol hydrocarbons, like light or white spirit combined with fractions derived from mineral oil. The use of aqueous oil, silicone or wax emulsions is also known as a rubber care product.

Nachteilig bei diesen Produkten ist die schlechte biologische Abbaubarkeit und bei den wässerigen Öl- bzw. Siliconemulsionen deren Frostempfindlichkeit, die eine Anwendung als Gummipflegemittel für Kraftfahrzeugtürdichtungen und Kraftfahrzeugfensterdichtungen bei tiefen Temperaturen einschränkt. Insbesondere bei den auf Basis von mineralölstämmigen Kohlenwasserstoffraktionen zusammengesetzten Gummipflegemitteln wird die Farbe des Gummis verändert und die Anwendung solcher Pflegemittel verleiht dem Gummi einen unerwünschten Oberflächenglanz.The disadvantage of these products is the poor biodegradability and the aqueous oil or silicone emulsions their frost sensitivity, the one Application as a rubber care product for motor vehicle door seals and motor vehicle window seals restricted at low temperatures. Especially with the composed on the basis of mineral oil-derived hydrocarbon fractions Rubber care products change the color of the rubber and the application such care agent gives the rubber an undesirable surface gloss.

Zur Vermeidung von Nachteilen, die beispielsweise durch den Einsatz mineralölhaltiger Schmiermittel, Schalöle und Bohremulsionen hervorgerufen werden, ist der Einsatz von Ölen und Ölemulsionen auf der Basis von nativen Esterölen vorgeschlagen worden, vgl. DE 34 19 415 A1.To avoid disadvantages, for example due to the use of mineral oil Lubricants, formwork oils and drilling emulsions are the cause Use of oils and oil emulsions based on native ester oils proposed been, cf. DE 34 19 415 A1.

Es ist auch bekannt, daß technisches Ricinusöl als Schmiermittel für Hochleistungs-Verbrennungsmotoren eingesetzt worden ist, vgl. DE 41 38 910 A1.It is also known to use castor oil as a lubricant for high performance internal combustion engines has been used, cf. DE 41 38 910 A1.

US-A-5 338 471 offenbart zusammensetzungen enthaltend pflanzliche oder tiesiche Triglyzeride, Ester erhalten durch Transesterifikation tierischer oder pflanzlicher öle, Stockpunktserniedriger und Additive als Motorenöle und Schmiermittel.US-A-5 338 471 discloses compositions containing vegetable or deep triglycerides, Ester obtained by transesterification of animal or vegetable oils, pour point low and Additives as motor oils and lubricants.

Die erfindungsgemäßen Zusammensetzungen aus Rapsölmethylester und Rapsöl weisen die folgenden Anteile auf: 90 bis 5 Gew.-% Rapsölmethylester, 80 bis 5 Gew.-% Rapsöl, 0 bis 10 Gew.-% Carnaubawachs, 0 bis 10 Gew.-% Siliconöl, 0 bis 5 Gew.-% Polytetrafluorethylenpulver, 0 bis 1 Gew.-% fluorierter Alkylester, 0 bis 1 Gew.-% nichtionogener Emulgator. The rapeseed oil methyl ester and rapeseed oil compositions according to the invention have the following proportions: 90 to 5% by weight Rapsölmethylester, 80 to 5% by weight Rapeseed oil, 0 to 10% by weight carnauba wax, 0 to 10% by weight Silicone oil, 0 to 5% by weight polytetrafluoroethylene 0 to 1% by weight fluorinated alkyl ester, 0 to 1% by weight non-ionic emulsifier.

Bei teilweiser oder vollständiger Substitution des Anteils an Rapsölmethylester durch Rapsölethylester resultieren Zusammensetzungen mit verbessertem Kälteverhalten bei der Verwendung als Gummipflegemittel.With partial or complete substitution of the proportion of rapeseed oil methyl ester rapeseed oil ethyl ester results in compositions with improved cold behavior when used as a rubber care product.

Für bestimmte Anwendungen, beispielsweise Hartgummi, sind Abmischungen mit Zusätzen von 0,001 bis 1,0 Gew.-% fluorierter Alkylester als Netzmittel vorteilhaft.For certain applications, such as hard rubber, blends are included Additions of 0.001 to 1.0% by weight of fluorinated alkyl esters are advantageous as wetting agents.

Falls es auf besonders gute Oberflächengleiteigenschaften ankommt, kann hier durch Zusätze von 0,001 bis 10 Gew.-% Siliconöl (Methyl-, Phenylmethylsiliconöle) oder auch 0,001 bis 5 Gew.-% Polytetrafluorethylenpulver ein entsprechendes Verhalten eingestellt werden.If you need particularly good surface sliding properties, you can do so here by adding 0.001 to 10% by weight silicone oil (methyl, phenylmethyl silicone oils) or 0.001 to 5% by weight of polytetrafluoroethylene powder can be set.

Als nichtionogene Emulgatoren, die in Mengen von vorzugsweise 0 bis 1,0 Gew.-% zugesetzt werden können, haben sich Oxoalkohole als günstig erwiesen.As nonionic emulsifiers, which are used in amounts of preferably 0 to 1.0% by weight can be added, oxo alcohols have proven to be favorable.

Die Verwendung als Gummipflegemittel wird vorgeschlagen insbesondere im Kraftfahrzeugbereich für die bereits erwähnten Tür- und Fensterdichtungen, aber auch für Windschutzscheibendichtungen, Kofferraumdichtungen u. dgl., sowie bei entsprechenden Gummidichtungen im Bootsbereich.The use as a rubber care product is proposed, particularly in the motor vehicle sector for the door and window seals already mentioned, but also for windshield seals, trunk seals u. Like., And with appropriate Rubber seals in the boat area.

Die angegebenen Zusammensetzungen sind wirksam bei natürlichen und synthetischen Kautschuken und können beispielsweise bei der Pflege der Flanken von Fahrzeugreifen, von Fenster- und Türdichtungen im Wohn- oder Industriebereich, von Griffstücken, Handschuhen, Schuhen, Kabeln, Latexartikeln u. dgl. von Nutzen sein.The compositions indicated are effective for natural and synthetic Rubbers and can, for example, in the care of the flanks of Vehicle tires, from window and door seals in residential or industrial areas, of grips, gloves, shoes, cables, latex items and the like. Like. useful his.

Die angegebenen Mittel erhalten Gummi in unterschiedlicher Shore-Härte, wie sie insbesondere am Kraftfahrzeug verwendet werden, geschmeidig und verleihen den Produkten ein gepflegtes Äußeres.The specified agents receive rubber in different Shore hardness, as they do used in particular on the motor vehicle, smooth and lend the Products a neat appearance.

So läßt sich die Gummielastizität derartiger Elastomere durch die Verwendung der angegebenen Zusammensetzungen länger erhalten und die Verschlechterung der Materialeigenschaften durch Oxidation, Verschmutzung und UV-Strahlung wird wirksam gebremst.So the rubber elasticity of such elastomers by using the specified compositions received longer and the deterioration of Material properties due to oxidation, pollution and UV radiation become effective braked.

Die biologische Abbaubarkeit der angegebenen Zusammensetzung ist als gut zu bezeichnen. So wird Rapsöl nach der CEC- L 33T 82-Methode innerhalb von 21 Tagen um mindestens 80 % abgebaut, während dies bei Mineralölen nur zu 15 - 20 % der Fall ist. Auch die Abbaubarkeit von Rapsölmethylester ist besser als diejenige der an sich für die angegebene Verwendung ebenfalls in Betracht kommenden mineralölstämmigen Fraktionen.The biodegradability of the specified composition is considered to be good too describe. Thus, rapeseed oil is produced within 21 after the CEC-L 33T 82 method Days reduced by at least 80%, while this is only 15 - for mineral oils 20% is the case. The degradability of rapeseed oil methyl ester is also better than that which in itself also comes into consideration for the specified use mineral oil-derived fractions.

Eine für die Verwendung als Gummipflegemittel besonders geeignete und bevorzugte Rezeptur hat die folgende Zusammensetzung: 50,0 Gew.-% Rapsölmethylester 48,5 Gew.-% Rapsöl 1,0 Gew.-% Methyl-Siliconöl 500 0,5 Gew.-% Oxoalkohol. A recipe that is particularly suitable and preferred for use as a rubber care product has the following composition: 50.0% by weight Rapsölmethylester 48.5% by weight rapeseed oil 1.0% by weight Methyl silicone oil 500 0.5% by weight Oxo alcohol.

Eine andere im Rahmen der Erfindung liegende Rezeptur im Sinne eines Ausführungsbeispiels hat die Zusammensetzung: 50,0 Gew.-% Rapsölmethylester 49,0 Gew.-% Rapsöl 1,0 Gew.-% Polytetrafluorethylenpulver. Another recipe within the scope of the invention in the sense of an embodiment has the composition: 50.0% by weight Rapsölmethylester 49.0% by weight rapeseed oil 1.0% by weight Polytetrafluoroethylene.

Die damit erzielten Ergebnisse (Bewitterungstest, UV-Bestrahlungstest, Ozonbehandlungstest oder dgl.) lassen sich wie folgt zusammenfassen:The results achieved with this (weathering test, UV radiation test, ozone treatment test or the like) can be summarized as follows:

Bewitterungstests erfolgten durch Anwendung am PKW über eine Laufleistung von ca. 10.000 km.Weathering tests were carried out on a car with a mileage of approx. 10,000 km.

Die Beständigkeit gegenüber Beregnung und UV-Strahlung ist geringer einzustufen als bei herkömmlichen Mineralölprodukten, dennoch ist der Pflegeeffekt als gut zu bezeichnen. Dieses Ergebnis überrascht insofern nicht, da die biologische Abbaubarkeit gegeben ist. Die behandelten Gummiteile behielten deutlich länger ein gepflegtes Äußeres und wurden nicht so schnell unansehnlich.The resistance to irrigation and UV radiation is lower than with conventional mineral oil products, yet the care effect is good too describe. This result is not surprising in that the biodegradability given is. The treated rubber parts kept a well-groomed one for much longer Appearance and did not quickly become unsightly.
