Description

Die Erfindung betrifft eine flüssige Kettensägefluid-Zusammensetzung sowie ein Verfahren zur Herstellung derselben.The invention relates to a liquid chainsaw fluid composition and to a process for producing the same.

Derzeit existieren am Markt zwei Arten von Kettensägeölen, nämlich biologisch nicht abbaubare auf Mineralölbasis sowie biologisch abbaubare auf Basis nativer und synthetischer Öle.There are currently two types of chain saw oils on the market, namely non-biodegradable mineral oil based and biodegradable based on native and synthetic oils.

Produkte auf Mineralölbasis sind nicht biologisch abbaubar und dürfen dadurch zur Versorgung von Kettensägen nicht verwendet werden. Aufgrund der günstigen Preise und nicht notwendiger Reinigung des Kettensägeschwertes und der Kette finden diese Öle in der Praxis jedoch noch immer Verwendung.Mineral oil-based products are not biodegradable and must not be used to power chainsaws. Due to the low prices and unnecessary cleaning of Kettensägeschwertes and the chain, however, these oils are still used in practice.

Produkte auf Basis nativer Öle (z.B.: Rapsöl, Sojaöl, Rüböl) oder synthetischer Ester bilden die Gruppe der biologisch abbaubaren Kettenöle. Ihr Vorteil ist natürlich die biologische Abbaubarkeit. Zu den Nachteilen der Produkte auf Basis nativer Öle zählen die schlechte Oxidationsstabilität, d.h. diese Produkte unterliegen bei Einwirkung von UV-Strahlung und/oder Einwirkung von höherer Temperatur einer Oxidation und somit einem Verharzen. Dadurch bildet sich auf Schwert und Kette eine sehr zähe bis feste, klebrige und nur unter großem Aufwand abwaschbare Schicht. Auch sind diese Öle wesentlich teurer (z.B. synthetischer Ester 4-6 fach) als Mineralölprodukte. Ein weiterer Nachteil von Ölen allgemein ist, dass sie auf Wasser Schlieren bilden. Sollte es im Bereich von Gewässern zu einem Austritt von Öl kommen, so bilden sich am Wasser Ölschlieren. Es ist jedoch visuell nicht feststellbar, ob es sich um ein biologisch abbaubares Produkt oder um Mineralöl handelt. Es muss dann ein Öleinsatz der Feuerwehr erfolgen, welcher zu enormen Kosten führen kann.Products based on natural oils (eg rapeseed oil, soybean oil, rapeseed oil) or synthetic esters form the group of biodegradable chain oils. Their advantage is of course the biodegradability. The disadvantages of the native oil based products include poor oxidation stability, i. These products are subject to oxidation and thus to resinification on exposure to UV radiation and / or higher temperature exposure. This forms on sword and chain a very tough to solid, sticky and washable only at great expense layer. Also, these oils are much more expensive (e.g., synthetic esters 4-6 times) than mineral oil products. Another disadvantage of oils in general is that they form streaks on water. Should there be an escape of oil in the area of water, oil streaks form on the water. However, it is not visually detectable whether it is a biodegradable product or mineral oil. It must then be an oil use of the fire department, which can lead to enormous costs.

Der Erfindung lag daher die Aufgabe zugrunde, die genannten Nachteile weitgehend auszuschließen und eine Kettensägefluid-Zusammensetzung bereitzustellen, die biologische Abbaubarkeit gewährleistet, der Wassergefährdungsklasse WGK 1 (schwach wassergefährdend) genügt und die Oxidationsstabilität besitzt. Ferner sollte dieses Kettensägefluid kostengünstiger als die am Markt befindlichen sein.The invention was therefore based on the object to largely exclude the disadvantages mentioned and to provide a chainsaw fluid composition that ensures biodegradability, the water hazard class WGK 1 (slightly hazardous to water) is sufficient and has the oxidation stability. Furthermore, this chainsaw fluid should be cheaper than those on the market.

Vorstehende Aufgabe wird durch die flüssige Kettensägefluid-Zusammensetzung nach Anspruch 1 gelöst, die 1 bis 30 Gew.-% Wasser, bis 0,5 Gew.-% Methanol, 50 bis 95 Gew.-% Glycerin, bis 1,5 Gew.-% Tensid, bis 20 Gew.-% Haftklebstoff, gegebenenfalls bis 2,0 Gew.-% Korrosionsschutzmittel und/oder gegebenenfalls bis 1 Gew.-% Duftstoff umfasst.The above object is achieved by the liquid chainsaw fluid composition according to claim 1 containing 1 to 30% by weight of water, up to 0.5% by weight of methanol, 50 to 95% by weight of glycerol, up to 1.5% by weight. % Surfactant, to 20 wt .-% pressure-sensitive adhesive, optionally up to 2.0 wt .-% corrosion inhibitor and / or optionally to 1 wt .-% perfume comprises.

Vorteilhafte Ausgestaltungen dieser flüssigen Kettensägefluid-Zusammensetzung ergeben sich aus den Unteransprüchen 2 bis 13 Anspruch 14 beschreibt ein Verfahren zur Herstellung dieser flüssigen Kettensägefluid-Zusammensetzung.Advantageous embodiments of this liquid chainsaw fluid composition will become apparent from the dependent claims 2 to 13 claim 14 describes a method for producing this liquid chainsaw fluid composition.

Die erfindungsgemäße Kettensägefluid-Zusammensetzung ist zunächst frei von Mineralöl, nativen Ölen oder synthetischen Estern. Ferner sind alle Bestandteile der erfindungsgemäßen Kettensägefluid-Zusammensetzung biologisch abbaubar. Die erfindungsgemäße Kettensägefluid-Zusammensetzung ist daher nicht umweltschädlich. Die erfindungsgemäße Kettensägefluid-Zusammensetzung ist der Wassergefährdungsklasse 1 zuzuordnen. Die erfindungsgemäße Kettensägefluid-Zusammensetzung kann daher in Wasserschutzgebieten eingesetzt werden. Ferner ist die erfindungsgemäße Kettensägefluid-Zusammensetzung gegenüber UV-Strahlung stabil und selbst bei Anwendung über einen Zeitraum von 18 Monaten erfolgt keine Oxidation. Schließlich hat sich gezeigt, dass die erfindungsgemäße Kettensägefluid-Zusammensetzung gegenüber Temperaturschwankungen unempfindlich ist. Ausgehend von den zum Zeitpunkt der Einreichung aktuellen Rohstoffpreise zeigt die erfindungsgemäße Kettensägefluid-Zusammensetzung um etwa 50 % geringere Kosten als herkömmliche Kettensäge-Öle.The chainsaw fluid composition of the present invention is initially free of mineral oil, native oils or synthetic esters. Furthermore, all components of the chainsaw fluid composition of the invention are biodegradable. The chainsaw fluid composition according to the invention is therefore not harmful to the environment. The chainsaw fluid composition according to the invention is assigned to the water hazard class 1. The chainsaw fluid composition according to the invention can therefore be used in water protection areas. Furthermore, the chainsaw fluid composition of the present invention is stable to UV radiation, and even when used over a period of 18 months, there is no oxidation. Finally, it has been found that the chainsaw fluid composition according to the invention is insensitive to temperature fluctuations. Based on current commodity prices at the time of filing, the inventive chainsaw fluid composition is approximately 50% less costly than conventional chainsaw oils.

Hinzu kommt, dass der Hauptteil der erfindungsgemäßen Kettensägefluid-Zusammensetzung ein Raffinationsnebenprodukt der Biodieselherstellung sein kann. Dieses Nebenprodukt ist eine unangenehm riechende Flüssigkeit, die bisher der Verbrennung zugeführt bzw. aufwändig weiterverarbeitet werden musste. Die erfindungsgemäße Kettensägefluid-Zusammensetzung ermöglicht nun den direkten Einsatz dieses Raffinationsnebenproduktes in einer flüssigen Zusammensetzung, die überraschende Eigenschaften bei der Verwendung als Kettensägefluid-Zusammensetzung zeigt.In addition, the majority of the inventive chainsaw fluid composition may be a refining by-product of biodiesel production. This by-product is an unpleasant smelling liquid that previously had to be incinerated or extensively processed. The chainsaw fluid composition of the present invention now enables the direct use of this refining by-product in a liquid composition that exhibits surprising properties when used as a chainsaw fluid composition.

Anstelle dieses Nebenproduktes kann auch technisches Glycerin bzw. ein Gemisch der beiden eingesetzt werden.Instead of this by-product, technical glycerol or a mixture of the two can also be used.

Neben den oben geschilderten Vorteilen wurde festgestellt, dass die erfindungsgemäße flüssige Kettensägefluid-Zusammensetzung hinsichtlich der anderen Eigenschaften, wie Anhaftung, Verbrauch, Korrosionsschutz, UV-Beständigkeit, Verschleißschutz den bekannten Kettensäge-Ölen entspricht.In addition to the above-mentioned advantages, it has been found that the liquid chainsaw fluid composition according to the invention in terms of other properties, such as adhesion, consumption, corrosion protection, UV resistance, wear protection of the known chainsaw oils.

Vorteilhafterweise besitzt die erfindungsgemäße Kettensägefluid-Zusammensetzung eine Viskosität von 50 bis 400 mm2/sec, insbesondere von 120 bis 240 mm2/sec. Eine zu hohe Viskosität hat den Nachteil, dass die Förderbarkeit bei tiefen Temperaturen nicht genügt und die Kosten zu hoch ansteigen, während eine zu niedrige Viskosität dazu führt, dass eine ausreichende Schmierung nicht gewährleistet ist. Als besonders vorteilhaft haben sich Viskositäten von 120 bis 240 mm2/sec erwiesen, da eine optimale Versorgung bei geringstem Verbrauch erzielt werden kann.Advantageously, the chainsaw fluid composition according to the invention has a viscosity of 50 to 400 mm 2 / sec, in particular from 120 to 240 mm 2 / sec. Too high a viscosity has the disadvantage that the conveyance at low temperatures is not sufficient and the costs rise too high, while too low a viscosity results in that sufficient lubrication is not guaranteed. Viscosities of 120 to 240 mm 2 / sec have proven to be particularly advantageous, since optimum supply can be achieved with the lowest consumption.

Die Viskositäten wurden mit dem Rotationsviskosimeter Brookfield LVDW-II+ mit folgenden Einstellungen gemessen: Spindel Nr. 18, Umdrehungen/min: 7,5 ; 12 ; 17 ( DIN 53019 Teil 1 (Mai 1980).The viscosities were measured with the Brookfield LVDW-II + rotational viscometer with the following settings: spindle no. 18, revolutions / min: 7.5; 12; 17 (DIN 53019 Part 1 (May 1980).

Bei dem in der erfindungsgemäßen Kettensägefluid-Zusammensetzung eingesetzten Tensid handelt es sich vorteilhafterweise um sulfatierte Pflanzenöle. Diese haben den Vorteil, dass sie biologisch abbaubar sind und über ein hervorragendes Verschleißschutzverhalten verfügen. Als besonders geeignet haben sich sulfatierte Produkte aus Palmöl, Kokosnussöl, Rizinusöl, Rapsöl, Sonnenblumenöl, Sojaöl oder Gemische davon erwiesen. Besonders bevorzugt ist der Einsatz von Türkischrotöl (sulfatiertes Rizinusöl). Das eingesetzte Tensid wird in einer Menge von bis zu 1,5 Gew.-%, vorzugsweise von bis zu 1 Gew.-% eingesetzt.The surfactant used in the chain saw fluid composition of the present invention is advantageously sulfated vegetable oils. These have the advantage that they are biodegradable and have an excellent wear protection behavior. Sulfated products of palm oil, coconut oil, castor oil, rapeseed oil, sunflower oil, soybean oil or mixtures thereof have proven to be particularly suitable. Particularly preferred is the use of Turkish red oil (sulfated castor oil). The surfactant used is used in an amount of up to 1.5% by weight, preferably up to 1% by weight.

Der in der erfindungsgemäßen Kettensägefluid-Zusammensetzung eingesetzte Haftklebstoff ist vorzugsweise ein Vinylpyrrolidon-Homopolymer. Vinylpyrrolidon-Homopolymere haben den Vorteil, dass sie biologisch abbaubar sind, viskositätserhöhend wirken und die Anhaftung des Fluids an der Kette erhöhen. Der K-Wert dieser Vinylpyrrolidon-Homopolymere liegt vorteilhafterweise zwischen 80 und 140. Das Molekulargewicht (Mw) der Vinylpyrrolidon-Homopolymere liegt vorteilhafterweise zwischen 1.000 und 3.000 KDalton liegen. Die Glasübergangstemperaturen (DSC) der eingesetzten Vinylpyrrolidon-Homopolymere liegen vorteilhafterweise bei 160 bis 200 °C, insbesondere etwa 180 °C. Ferner ist es von Vorteil, dass der Haftklebstoff, sowohl in hydrophoben als auch in hydrophilen Lösungsmitteln eine universale Löslichkeit besitzt. Der Haftklebstoff wird in einer Menge von bis 20 Gew.-%, vorzugsweise in einer Menge von bis 1 Gew.-% bis 10 Gew.-% eingesetzt, da dadurch die optimale Viskosität und Anhaftung des Fluides erzielt wird.The pressure-sensitive adhesive used in the inventive chainsaw fluid composition is preferably a vinylpyrrolidone homopolymer. Vinyl pyrrolidone homopolymers have the advantage that they are biodegradable, have a viscosity-increasing effect and increase the attachment of the fluid to the chain. The K value of these vinylpyrrolidone homopolymers is advantageously between 80 and 140. The molecular weight (Mw) of the vinylpyrrolidone homopolymers is advantageously between 1,000 and 3,000 KDaltons. The glass transition temperatures (DSC) of the vinylpyrrolidone homopolymers used are advantageously at 160 to 200 ° C, in particular about 180 ° C. Furthermore, it is advantageous that the pressure-sensitive adhesive has a universal solubility in both hydrophobic and hydrophilic solvents. The pressure-sensitive adhesive is used in an amount of up to 20% by weight, preferably in an amount of up to 1% by weight to 10% by weight, since this achieves the optimum viscosity and adhesion of the fluid.

In einer bevorzugten Ausführungsform enthält die erfindungsgemäße Kettensägefluid-Zusammensetzung ein Korrosionsschutzmittel. Bei der Auswahl des Korrosionsschutzmittels ist zunächst darauf zu achten, dass dieses wasserlöslich ist. Das Korrosionsschutzmittel wird in einer Menge von bis zu 2,0 Gew.-%, bevorzugt in einer Menge von bis zu 1,0 Gew.-%, besonders bevorzugt in einer Menge von bis zu 0,6 Gew.-%, eingesetzt. Bevorzugte Korrosionsschutzmittel sind Polycarbonsäuren, da diese biologisch abbaubar sind und sehr gute Korrosionsschutzwerte zeigen. Der Einsatz von Korrosionsschutzmitteln hat den Vorteil, dass ein Rosten des Schwertes der Kettensäge vermindert bzw. verhindert wird.In a preferred embodiment, the inventive chainsaw fluid composition contains a corrosion inhibitor. When selecting the anticorrosion agent, it must first be ensured that it is water-soluble. The corrosion inhibitor is used in an amount of up to 2.0% by weight, preferably in an amount of up to 1.0% by weight, more preferably in an amount of up to 0.6% by weight. Preferred corrosion inhibitors are polycarboxylic acids, since they are biodegradable and show very good corrosion protection values. The use of corrosion inhibitors has the advantage that rusting of the sword of the chainsaw is reduced or prevented.

Um den unangenehmen Geruch der erfindungsgemäßen Kettensägefluid-Zusammensetzung zu kompensieren, wird dieser in einer bevorzugten Ausführungsform auch ein wasserlöslicher Duftstoff zugesetzt. An die Anforderungen des Duftstoffes werden keine besonderen Bedingungen geknüpft. Beispielsweise können Tannennadelduft, Apfelduft, Zitronenduft, Mandarinenduft, Orangenduft sowie Gemische davon eingesetzt werden. Der Duftstoff wird in einer Menge von bis zu 1 Gew.-%, vorzugsweise in einer Menge von bis zu 0,5 Gew.-% und besonders bevorzugt in einer Menge von bis zu 0,3 Gew.-%, eingesetzt.In order to compensate for the unpleasant odor of the chainsaw fluid composition according to the invention, in a preferred embodiment, it is also added a water-soluble perfume. The requirements of the fragrance are not subject to any special conditions. For example, pine needles, apple scents, lemon scents, mandarin scents, orange scents and mixtures thereof can be used. The perfume is used in an amount of up to 1% by weight, preferably in an amount of up to 0.5% by weight and more preferably in an amount of up to 0.3% by weight.

Der Wassergehalt in der erfindungsgemäßen Kettensägefluid-Zusammensetzung beträgt 1 bis 30 Gew.-%. Ein zu niedriger Wassergehalt führt dazu, dass die zugesetzten Additive möglicherweise nicht vollständig eingerührt werden, während ein zu hoher Wassergehalt den Nachteil hat, dass das Fluid zu dünnflüssig wird und nicht haftet. Wassergehalte von 1 bis 25 Gew.-% haben den Vorteil, dass sie der Viskosität und der Anhaftung des Kettensägefluids entsprechen. Besonders bevorzugt ist ein Wassergehalt von 1,0 bis 5 Gew.-%The water content in the chainsaw fluid composition of the present invention is 1 to 30% by weight. Too low a water content causes the added additives may not be stirred completely, while too high a water content has the disadvantage that the fluid is too thin and does not adhere. Water contents of 1 to 25 wt .-% have the advantage that they correspond to the viscosity and the adhesion of the chainsaw fluid. Particularly preferred is a water content of 1.0 to 5 wt .-%

Methanol ist in einer Menge von bis 0,5 Gew.-% im Produkt aufgrund des Herstellungsprozesses des Basisfluids vorhanden.Methanol is present in an amount of up to 0.5% by weight in the product due to the manufacturing process of the base fluid.

Der Glyceringehalt der erfindungsgemäßen Kettensägefluid-Zusammensetzung liegt zwischen 50 bis 95 Gew.-%. Ein zu niedriger Glyceringehalt hat den Nachteil, dass die erforderliche Viskosität nicht erreicht wird. Vorteilhafterweise liegt der Glyceringehalt zwischen 55 Gew.-% bis 95 Gew.-%, insbesondere zwischen 65 Gew.-% bis 77 Gew.-% oder zwischen 90 Gew.-% bis 95 Gew.-%.The glycerol content of the chainsaw fluid composition of the invention is between 50 to 95% by weight. Too low a glycerine content has the disadvantage that the required viscosity is not reached. Advantageously, the glycerol content is between 55 wt .-% to 95 wt .-%, in particular between 65 wt .-% to 77 wt .-% or between 90 wt .-% to 95 wt .-%.
