Description
AT396477B
Die Erfindung betrifft ein eßbares Schmiermittel, das vor allem in Hochdruckkompressoren verwendet weiden kann.
Als "eßbar" oder "genießbar" bezeichnete, also praktisch ungiftige Schmiermittel benötigt man bekanntlich zur Schmierung von Maschinenteilen, wenn Anteile - meist nur Spuren - des Schmiermittels mittelbar oder unmittelbar in Nahrungs-, Genuß- und Lebensmittel gelangen können. Sie sind aber auch im Hinblick auf die geringere Schädlichkeit für die Umwelt von Vorteil, verglichen mit herkömmlichen, manchmal giftige Substanzen enthaltenden Schmiermitteln. Eßbare Substanzen sind entweder a) ungiftig und verdaulich, wie beispielsweise pflanzliche und tierische Fette und Öle oder b) ungiftig, weil unlöslich und chemisch inert, wie beispielsweise Paraffinum-liquidum, das unverdaut ausgeschieden wird.
Das erfindungsgemäße Schmiermittel ist ein Gemisch bestehend zum Großteil aus der Gruppe b) in Form der Basis-Schmiermittelmischung sowie aus den eßbaren Stoffen der Gruß» a) in Form von Additiven.
Es eignet sich insbesondere für Hochdruckkompressoren, die zur Herstellung von Polyolefinen (Hochdruck-Polyäthylen und -Polypropylen) aus den entsprechenden monomeren Gasen dienen, wobei diese Kompressoren Drücke von 1500 bis vornehmlich 3500 bar erzeugen. Die aus dem solcherart produzierten Hochdruck-Polyäthylen oder -Polypropylen hergestellten Folien werden auch zur Verpackung von Lebensmitteln verwendet. Die darin enthaltenen Spuren von Schmiermitteln können zum Teil in die damit in Berührung kommenden Lebensmittel gelangen und müssen daher genießbar sein.
Schmiermittel dieser Art und für diesen Zweck sind bekannt. In der DE-PS 2137590 wird ein solches Schmiermittel beschrieben, das aus einem weißen Mineralöl und 5 bis 50 %, vorzugsweise 20 bis 40 % eines Polybutens und 0,1 bis 1,0 %, vorzugsweise 0,1 bis 0,5 % einer Fettsäure mit 16 bis 18 Kohlenstoffatomen und/oder einem niederen Alkylester einer derartigen Fettsäure, sowie 0,01 bis 2 % eines Antioxidationsmittels (eines o-tert. Alkyl-substituierten Phenols) besteht. Die Fettsäuren oder deren niedere Alkylester, die als Additive zur Erhöhung der Schmierfähigkeit des Schmiermittels lL DE-PS 2137590 verwendet werden, bestehen aus gesättigten oder ungesättigten aliphatischen Monocarbonfettsäuren mit 8 bis 22 Kohlenstoffatomen sowie aus mehreren niederen Alkylestem, wobei die Alkylester bis zu ungefähr 5 Kohlenstoffatome enthalten, z. B. Methyloleat, n-Butylstearat oder dergleichen.
Das erfindungsgemäße Schmiermittel, vor allem in Bezug auf die Additive, ist neu und unterscheidet sich wesentlich von der erwähnten DE-PS 2137590.
Die Art und die mengenmäßigen Anteile der Additive sind von ausschlaggebender Bedeutung für die Qualität des Schmiermittels. Geringe Abweichungen von der Rezeptur können bereits zu starker Qualitätsverminderung führen. Aus diesem Grund kommt dem eifindungsgemäßen Schmiermittel eine große Erfindungshöhe zu, zumal eine ungeheure Anzahl von unterschiedlichen Additiven jeweils in zahlreichen Kombinationen, Mischungsverhältnissen und Konzentrationen untersucht werden muß.
Das erfindungsgemäße Schmiermittel unterscheidet sich wesentlich von der DE-PS 2137590 dadurch, daß es keine freien Fettsäuren enthält, die bekanntlich zu Korrosion führen (können); weiters enthält es keine niederen Alkylfettsäureester. Ferner besteht es nicht aus ungesättigten Fettsäuren oder deren niederen Alkylfettsäureestem, wie z. B. Ölsäure, Linolsäure, Linolensäure, deren chemische und thermische Stabilität sich als nicht optimal erweist.
Das erfindungsgemäße Schmiermittel enthält vielmehr - als Additive zu Verbesserung der Schmierwirkung -nur gesättigte Fettsäurederivate, in denen erstens keine freie Säuregruppe (Carboxylgruppe, COOH) und zweitens keine "ungeschützte" Zwei- oder Mehrfachbindung vorkommt; außerdem handelt es rieh beim erfindungsgemäßen Schmiermittel nicht um Ester einwertiger Alkohole, sondern ausnahmslos um solche von höheren eßbaren Alkoholen. Zu letzteren gehören z. B.
Propylenglykol (2 alkoholische Hydroxylgruppen),
Glycerin (3 alkoholische Hydroxylgruppen),
Eiythrit (4 alkoholische Hydroxylgruppen, 4 C-Atome),
Pentaerythrit (4 alkoholische Hydroxylgruppen, 5 C-Atome),
Hexite (6 alkoholische Hydroxylgruppen),
Mannit, Sorbit, Arabit.
Als Ausnahme gilt hier das Rizinusöl, ein Triglycerid, das die Ricinolsäuie enthält, eine Hydroxy-Ölsäure; diese besitzt nicht die leichte Oxidierbarkeit und Neigung zur thermischen Instabilität der Ölsäure, weil sie durch ihre Hydroxylgruppe "geschützt" (abgeschirmt) wird. Ricinusöl ist chemisch und thermisch sehr stabil, im Gegensatz zu Ölsäure und deren Estern.
Selbstverständlich ist die chemische und thermische Stabilität der Additive von ausschlaggebend» Bedeutung für die Qualität des Schmiermittels.
Das erfindungsgemäße Schmiermittel enthält vorzugsweise mehr als ein Additiv in Form von eßbaren Estern, insbesondere mindestens je ein Additiv in Form eines Esters von gesättigten Fettsäuren mit einem 2-, einem 3-, -2-
AT 396 477 B einem 4· und einem 6-wertigen Alkohol, wobei Ricinusöl vorzugsweise jeweils eine Komponente daistellt D» Gehalt an schmierwirkungsverbessemden Additiven beträgt in Summe zwischen 0,1 bis 3,0 Gewichtsprozent bezogen auf das fertige Schmiermittel.
Die Fettsäuren des Ricinusöles setzen sich wie folgt zusammen: 87 bis 91 % Ricinolsäure, 2 % Stearin- und Palmitinsäure, 1 bis 2 % Dihydroxystearinsäure, aber auch aus 2 bis 3 % Ölsäure und 3 bis 5 % Linolsäure. Da die beiden letzteren Bestandteile ungesättigte Fettsäuren sind, ist - neben der schützenden Wirkung der Hydroxylgruppe - der Zusatz von Antioxidationsmittel(n) zum Schmiermittel vorgesehen. Hydriertes Ricinusöl ist ein bei 84 bis 86 °C schmelzendes Hartfett mit wachsähnlichen Eigenschaften; auch in dieser Form ist es ein Additiv zur Verbesserung der Schmierwirkung des erfmdungsgemäßen Schmiermittels.
Die Additive lösen sich in der mineralischen Schmierölbasis besser, wenn die Mischung erwärmt wird, vor allem über den Schmelzpunkt des Additives mit dem höchsten Schmelzpunkt. Eine praktische Begrenzung für die Anwendung der erfindungsgemäßen Additive ist ein zu hoher Schmelzpunkt, weil die Erwärmung und das Wannhalten der Schmierölmischung bei Temperaturen über beispielsweise 100 °C umständlich und ungünstig ist.
Als Beispiel für eine Rezeptur nur für die Additive zur Schmierwirkungsverbesserung wird eine aus 5 verschiedenen derartigen Additiven bestehende Mischung angegeben:
Additiv Ester aus Gehalt im fertigen (Bezeichnung) Alkohol Fettsäure Schmiermittel in Gew.% Ricinusöl Glycerin Ricinols. 0,05 bis 0,5 % Pentaerythritester Pentaerythrit Stearin-, Palmitins. 0,06 bis 0,6 % Äthylhexylpalmitat Äthylhexylalkohol Palmitins. 0,03 bis 0,3 % Äthylhexylstearat Äthylhexylalkohol Stearins. 0,03 bis 0,3 % Sorbitantrist. Sorbit Stearins. 0,03 bis 0,3 %
Das Basis-Schmierölgemisch besteht jeweils aus etwa 40 bis 60 % Weißöl und etwa 60 bis 40 % Polybuten und/oder Polyisobuten.
Als eßbares Antioxidationsmittel (Alterungsschutzmittel) enthält das erfindungsgemäße Schmiermittel 0,05 bis 0,1 % einer Pentaerythritverbindung, oder 0,05 bis 0,1 % einer Anisolverbindung oder 0,05 bis 0,1 % einer Mischung aus beiden Verbindungen im Verhältnis von ungefähr 1:1, vorzugsweise verstärkt durch 0,01 bis 0,1 % einer organischen Phosphitverbindung.
Die Vorteile des erfmdungsgemäßen Schmiermittels mit den Additiven auf Esterbasis sind wie folgt: 1. Optimale thermische und chemische Stabilität sowie Schmierwirkungsverbesserung und Abriebverminderung durch die Auswahl eßbarer gesättigter Fettsäuren für den Säureteil der Ester; 2. desgleichen durch die Auswahl eßbar» höher» Alkohole mit 2 bis 6 Alkoholgruppen (Hydroxylgruppen) für den Alkoholteil d» Ester. 3. Optimale Abdeckung möglichst viel» und großer B»eiche d» Temperatur, des Druckes, d» Verweilzeit, der mechanischen Parameter (relative Geschwindigkeit der bewegten zu schmierenden Teile; deren Werkstoffzusammensetzung, Reibungskoeffizienten u. a.) durch vorzugsweise mehrere - mindestens aber zwei - Komponenten, wobei vorzugsweise Ricinusöl oder hydriertes Ricinusöl jeweils eine Komponente sein soll. 4. Der Gehalt an Schmiermitteladditiven beträgt in Summe 0,1 bis 3,0 Gewichtsprozent, unabhängig von der Anzahl der Komponenten, so daß sich im wesentlichen keine Verteuerung des Schmiermittels mit zunehmender Anzahl der Komponenten ergibt. 5. Gewünschte physikalische und chemische Eigenschaften wie beispielsweise niedriger Schmelz-(Erstarrungs-, Stock-) Punkt, hoher Siede- und Zündpunkt, niedriger Dampfdruck u. a. des Schmiermittels können durch entsprechende gezielte Auswahl der Ester als Additive erhalten werden; mehrwertige Alkohole gestatten Esterbildung mit 1 bis 2,6-wertige Alkohole mit bis zu 6 Alkoholgruppen, wobei freie, nichtveresterte Alkoholgruppen bestimmte gewünschte Eigenschaften ergeben, z. B. niedrigen Schmelzpunkt, gute Löslichkeit in der Schmiermittelbasis, hohe Viskosität bei erhöhten Temperaturen, u. a. 6. Freie Säuren, die sich u. U. als Abbauprodukte (spurenweise) bilden, z. B. infolge d» Oxidation einer alkoholischen Hydroxylgruppe, können mit anderen freien Alkoholgruppen zur Bildung neutral -3-
Claims (7)
- AT396477B reagierender eßbarer Ester führen; diese Esterbildung wird dadurch gefördert, daß das entstehende Reaktionswasser bei der herrschenden hohen Temperatur durch Verdunstung oder Verdampfung aus dem Schmiermittel entweicht und daher das chemische Gleichgewicht zugunsten der Esterbildung verschoben wird (Gleichgewichtskonstante, Massaiwirkungsgesetz). Freie, nicht veresterte alkoholische Hydroxylgruppen können daher durch Säureabbindung einen Alterungsschutz des Schmiermittels bewirken.7. Die chemisch sehr stabilen Ester da- höhaen gesättigten Fettsäuren unterliegen bei höherer Temperatur und längerer Verweilzeit einer teilweisen Oxidation, wobei ein ß-Abbau eintritt, so daß das jeweilige Oxidationsprodukt stets die nächstniedrigere Fettsäure ist; so entsteht z. B. aus dem Stearat das · ebenfalls schmierwirksame - Palmitat, usw. Die Fettsäureester besitzen daher die Wirkung eines "innewohnenden, eingebauten” Alterungsschutzes und wirken somit ähnlich wie ein Antioxidationsmittel.8. Dadurch, daß die erfmdungsgemäßen Schmiermitteladditive freie Alkoholgruppen im Ester enthalten können, erspart man sich die Zumischung von Alkoholen, z. B. von Fettalkoholen, die nicht imma die gewünschten Eigenschaften ergeben und die manchmal nicht eßbar sind.9. Gegenüber dem an sich bekannten alternativen Weg, aus mehrwertigen Säuren, z. B. Adipinsäure oder Fruchtsäuren Ester zu bilden, haben die erfmdungsgemäßen Schmiermitteladditive den Vorteil, bei Teilveresterung neutrale Alkoholgruppen aufzuweisen, während sich bei Teilveresterung mehrwertiger Säuren freie Säuregruppen ergeben, die wegen Korrosionsgefahr unerwünscht sind. Das Schmiermittel enthält außerdem einen Metallinhibitor (Metallabbinder), einen Desaktivator, 0,005 bis 0,5 Gew.% der fertigen Schmiermittelmischung, in Form eines Succinimid-Derivates oder eines Aminosäure-Derivates, z. B. N-Acyl-Sarkosan. Als zweites Beispiel - diesmal für eine Mischung aus nur zwei schmierwirksamen Additiven - ist die folgende Rezeptur angegeben: Additiv Ester aus Gehalt im fertigen (Bezeichnung) Alkohol Fettsäure Schmiermittel in Gew.% Ricinusöl Glycerin Ricinols. 0,12 bis 1,25% Sorbitantristearat Sorbit Stearinsäure 0,08 bis 0,75% Summe: 0,2 bis 2,0% Gegebenenfalls enthält das Schmiermittel zusätzlich einen höheren eßbaren Alkohol als Lösungsmittel und/oder Lösungsvermittlcr für die Additive.
