Description
Reversibles Universalschmierfett In neuerer Zeit werden in zunehmendem Maße größere Anforderungen an die Leistungsfähigkeit von Schmierstoffen gestellt, so z. B. auch- auf dem Gebiete der Schmierstoffe, die für besondere Schmierverhältnisse eingesetzt sind, nämlich der Mineralschmierfette.Reversible universal grease In recent times, in increasing numbers Dimensions made greater demands on the performance of lubricants, so z. B. also in the field of lubricants for special lubrication conditions are used, namely the mineral greases.
Bekanntlich sind Schmierfette aus Kohlenwasserstoffölen, insbesondere Mineralschmierölfraktionen, und Seifen zusammengesetzt. Zu diesem Zweck werden Mineralöle mit seifenbildenden tierischen und/oder pflanzlichen und/oder synthetischen Fetten oder deren entsprechenden Fett= säuren zusammengebracht und mit Alkalien bzw. Erdalkalien in fester oder gelöster Form verseift. Werden bei der Verseifung Alkalilaugen, z. B. Natronlauge, verwendet, so erhält man Fette, die sich durch einen hohen Tropfpunkt von r 2o bis aoo° auszeichnen, Diese Schmierfette haben aber den Nachteil, daß ihre Beständigkeit gegen Wasser in den meisten Fällen sehr zu wünschen übrigläßt und daß sie -je nach ihrer Zusammensetzung bei Wärmebeanspruchung häufig zum Gelieren neigen, wobei eine mehr oder minder starke Ölabscheidung auftreten kann. Hierdurch ist eine ordnungsgemäße Schmierung nicht mehr gewährleistet. Verwendet man bei der Verseifung Erdalkalien, wobei im allgemeinen der Kalk wegen seiner Wirtschaftlichkeit an erster Stelle steht, so erhält man Fette, die bei verhältnismäßig niedrigem Tropfpunkt eine außerordentliche gute Wasserbeständigkeit zeigen. Diese Schmierfette sind aber noch wesentlich wärmeempfindlicher als die Natronseifenschmierfette und können schon bei Temperaturen unter ihrem Tropfpunkt bei längerer Verweilzeit 'in ihre Bestandteile zerfallen. Hierbei wird das Öl vollständig ausgeschieden, und die Seife verkrustet als feste harzartige Masse das Lager. Diese Eigenschaft liegt in der Natur des Kalkseifenschmierfettes begründet. Im Gegensatz zum Natronseifenschmierfett benötigt nämlich das Kalkseifenschmierfett eine bestimmte Menge Wasser, die zur Bildung eines stabilen, konsistenten Schmierfettes notwendig ist. Diese an sich geringen Mengen Wasser können beispielsweise schon aus dem Kalkseifenschmierfett entweichen, wenn es für längere Zeit einer Temperatur über 6o° ausgesetzt wird.It is known that lubricating greases made from hydrocarbon oils, in particular Mineral lubricating oil fractions, and soaps. For this purpose, mineral oils are used with soap-forming animal and / or vegetable and / or synthetic fats or their corresponding fatty acids and brought together with alkalis or alkaline earths saponified in solid or dissolved form. Are alkaline solutions, z. B. caustic soda is used to obtain fats that have a high dropping point from r 2o to aoo °, but these lubricating greases have the disadvantage that their Resistance to water in most cases leaves much to be desired and that, depending on their composition, they often gel when exposed to heat tend, whereby a more or less strong oil separation can occur. Through this proper lubrication is no longer guaranteed. If you use the Saponification of alkaline earths, with lime in general because of its economy comes first, you get fats that have a relatively low dropping point show an extraordinarily good water resistance. These greases but are much more sensitive to heat than the soda soap greases and can even at temperatures below their dropping point with a longer dwell time 'in their constituents disintegrate. Here the oil is completely excreted, and the soap encrusts the camp as a solid, resinous mass. This property lies Based on the nature of lime soap grease. In contrast to baking soda grease namely, the lime soap grease requires a certain amount of water, which for Formation of a stable, consistent grease is necessary. This in itself For example, small amounts of water can be extracted from the lime soap grease escape if it is exposed to a temperature above 60 ° for a long period of time.
Es wurde nun gefunden, daß man das Wärmeverhalten :von unter Verwendung von alkali- oder erdalkalimetallseifenhaltigen Schmierfetten wesentlich verbessern kann, wenn man denselben einen Ester oder ein Estergemisch aus Monocarbonsäuren, Polycarbonsäuren, Monooxycarbonsäuren oder Polyoxycarbonsäuren mit a4 bis 32 C-Atomen und acyclischen und/oder cyclischen einwertigen und/oder mehrwertigen Alkoholen mit z¢ bis 32 C-Atomen beimischt, vorzugsweise in Mengen von o,5 bis 1o Gewichtsprozent, bezogen auf das Gesamtschmierfett. Bei den Alkaliseifen enthaltenden Schmierfetten wird durch den Zusatz die Neigung zum Gelieren und 'die daraus bedingte Ölabscheidung verhindert. Bei den Erdalkaliseifen enthaltenden Schmierfetten erreicht man durch den gleichen Zusatz eine Vermeidung des Zerfallens derselben in die Komponenten, selbst wenn die Schmierfette längere Zeit einer Erwärmung oberhalb ihres Tropfpunktes ausgesetzt werden. Nach dem Abkühlen besitzen diese Schmierfette wieder ihren Ausgangszustand. Die Schmierfette sind somit reversibel und den Schmierfetten ohne Esterzusatz überlegen.It has now been found that the thermal behavior: from using of alkaline or alkaline earth metal soap containing lubricating greases significantly improve can, if the same is an ester or an ester mixture of monocarboxylic acids, Polycarboxylic acids, monooxycarboxylic acids or polyoxycarboxylic acids with a4 to 32 carbon atoms and acyclic and / or cyclic monohydric and / or polyhydric alcohols with z ¢ to 32 carbon atoms admixed, preferably in amounts of 0.5 to 10 percent by weight, based on the total grease. In the case of lubricating greases containing alkali soaps The addition increases the tendency to gel and the resulting oil separation prevented. In the case of the alkaline earth soap containing greases, through the same addition an avoidance of the disintegration of the same into the components, even if the greases are heated above their dropping point for a long time get abandoned. After cooling down, these greases are back to their original state. The lubricating greases are thus reversible and superior to lubricating greases without the addition of esters.
Die Herstellung vorstehender Schmierfette kann in folgender Weise durchgeführt werden: Beispiels Aus 11 Gewichtsprozent Knochenfett, 5,5 Gewichtsprozent Waltranfettsäure, 2,5 Gewichtsprozent Marmorkalkhydrat und 79,5.Gewichtsprozent Mineralöl E5o = 4,5. wird in bekannter Weise ein Mineralschmierfett hergestellt. Diesem Schmierfett werden nach der Verseifung, gegebenenfalls während des Abkühlens, 1,5 Gewichtsprozent eines Lanocerinsäureesters des Lanosterins C27 H.5 C H (OH) CH (OH) C O O C36 H49. hinzugefügt. Je nach der geforderten Konsistenz können die Mengen der seifenbildenden Komponenten variiert werden. Beispiel e 1o Gewichtsprozent Baumwollsaatöl, 5,5 Gewichtsprozent destillierte Tranfettsäure, 2,7 Gewichtsprozent Marmorkalkhydrat, 79,3 Gewichtsprozent Mineralöl E 5o = 6,5 und a,5 Gewichtsprozent Cerotinsäurecerylester C26 H 53 C O 0 C26 H53 werden wie nach Beispiel 1 verarbeitet. Statt der angegebenen Menge Marmorkalkhydrat können auch 1,46 Gewichtsprozent Natriumhydroxyd verwendet werden.The above lubricating greases can be produced in the following way: Example from 11 percent by weight bone fat, 5.5 percent by weight whale fatty acid, 2.5 percent by weight marble lime hydrate and 79.5 percent by weight mineral oil E50 = 4.5. a mineral grease is produced in a known manner. After saponification, if necessary during cooling, 1.5 percent by weight of a lanoceric acid ester of lanosterol C27 H.5 CH (OH) CH (OH) COO C36 H49 are added to this lubricating grease. added. Depending on the consistency required, the amounts of the soap-forming components can be varied. Example e 1o percent by weight cottonseed oil, 5.5 percent by weight distilled trans-fatty acid, 2.7 percent by weight marble lime hydrate, 79.3 percent by weight mineral oil E 50 = 6.5 and a, 5 percent by weight cerotic acid ceryl ester C26 H 53 C O 0 C26 H53 are processed as in Example 1 . Instead of the specified amount of marble lime hydrate, 1.46 percent by weight sodium hydroxide can also be used.
Die die erfindungsgemäßen Zusätze enthaltenden Schmierfette sind reversibel und zeigen sich gegenüber den bekannten Schmierfetten, die nur Alkali-bzw. Erdalkaliseifen enthalten, überlegen, wie dieses die folgenden Vergleichsversuche zeigen.The lubricating greases containing the additives according to the invention are reversible and show up compared to the known lubricating greases, which are only alkali or. Alkaline earth soaps contain, consider how this shows the following comparison tests.
Um das Verhalten von Schmierfetten bei Temperaturen unterhalb ihres Tropfpunktes studieren und in eindeutiger Weise schnelle Aussagen über die Reversibilität des Fettes nach dem Abkühlen erhalten zu können, wird eine einfache Versuchsanordnung gewählt. Diese besteht aus einem normalen Jenaer Becherglas von 6oo ccm Inhalt, hoher Form und einem kreisrunden Drahtsieb von 12 cm Durchmesser und 784 Maschen pro cm2. Dieses Sieb wird auf die Öffnung des Becherglases gelegt, die Ränder leicht umgebördelt und das Sieb zu einer leichten Mulde eingedrückt, so daß sich 1o g zu prüfendes Schmierfett in dieser Mulde in einer o,5 cm dicken Schicht verteilen lassen. Das so präparierte Becherglas wird in einen Trockenschrank gebracht und 24 Stunden bei einer Temperatur von 2 bis 5° C unterhalb der Tropfpunktstemperatur des zu prüfenden Fettes stehengelassen. Nach dem Abkühlen wird der Durchlauf durch das Sieb in Prozent, bezogen auf die Schmierfetteinlage, ermittelt und der auf dem Sieb verbleibende Rückstand auf sein äußeres Aussehen und seine Struktur geprüft.In order to be able to study the behavior of lubricating greases at temperatures below their dropping point and to be able to obtain unambiguous quick statements about the reversibility of the grease after cooling, a simple test arrangement is chosen. This consists of a normal Jena beaker with a capacity of 600 ccm, tall form and a circular wire sieve with a diameter of 12 cm and 784 meshes per cm2. This sieve is placed on the opening of the beaker, the edges slightly flanged and the sieve pressed into a slight depression so that 10 g of the lubricating grease to be tested can be distributed in this depression in a 0.5 cm thick layer. The beaker prepared in this way is placed in a drying cabinet and left to stand for 24 hours at a temperature of 2 to 5 ° C. below the dropping point temperature of the fat to be tested. After cooling, the percentage of passage through the sieve based on the lubricating grease insert is determined and the residue remaining on the sieve is checked for its external appearance and structure.
Bei der Durchführung von Vergleichsversuchen an Schmierfetten, die einerseits nur an sich bekannte Zusätze von Alkali- bzw. Erdalkaliseifen (Versuchsbeispiele a) und andererseits bei gleicher Schmierfettzusammensetzung einen Zusatz gemäß der Erfindung (Versuchsbeispiele b) enthalten, werden die folgenden Ergebnisse erzielt. Zur Durchführung der Versuche werden die Schmierfette in gleicher Weise wie nach den obigen Ausführungsbeispielen 1 und 2 hergestellt: Erster Vergleichsversuch a) Schmierfett ohne erfindungsgemäßen Zusatz: 1o Gewichtsprozent Baumwollsaatöl, 5,5 Gewichtsprozent destillierte Tranfettsäure, 1,5 Gewichts--prozent NaOH, fest, 83 Gewichtsprozent Mineralöl E56 = 6,5. Nach 24 Stunden bei 14o° C sind 82 Gewichtsprozent des Schmierfettes durch das Sieb hindurchgelaufen. Auf dem Sieb verbleiben gummiartige Rückstände.When carrying out comparative tests on lubricating greases that on the one hand only known additions of alkali or alkaline earth soaps (test examples a) and on the other hand, with the same lubricating grease composition, an additive according to Invention (Experimental Examples b) contain the following results. To carry out the tests, the greases are used in the same way as after the above embodiments 1 and 2 produced: First comparative experiment a) Lubricating grease without additive according to the invention: 10 percent by weight cottonseed oil, 5.5 Weight percent distilled trans fatty acid, 1.5 weight percent NaOH, solid, 83 Percentage by weight of mineral oil E56 = 6.5. After 24 hours at 14o ° C, this is 82 percent by weight of the grease has passed through the sieve. Rubber-like remains on the sieve Residues.
b) Schmierfett mit erfindungsgemäßem Zusatz: 1o Gewichtsprozent Baumwollsaatöl, 5,5 Gewichtsprozent destillierte Tranfettsäure, 1;5 Gewichtsprozent Na O H, fest 8o,5 Gewichtsprozent Mineralöl E56 = 6,5, 2,5 Gewichtsprozent Cerotinsäurecerylester. Nach 24 Stunden bei 14o° C sind nur 61 Gewichtsprozent des Schmierfettes durch das Sieb hindurchgelaufen. Der Fettrückstand ist in der Konsistenz jedoch nicht mehr gummiartig.b) Lubricating grease with an additive according to the invention: 1o percent by weight of cottonseed oil, 5.5 percent by weight of distilled trans-fatty acid, 1.5 percent by weight of Na O H, solid 80.5 percent by weight mineral oil E56 = 6.5, 2.5 percent by weight cerotic acid ceryl ester. After 24 hours at 14o ° C are only 61 percent by weight of the grease passed through the sieve. The fat residue is in consistency however no longer rubbery.
Zweiter Vergleichsversuch a) Schmierfett ohne erfindungsgemäßen Zusatz: II Gewichtsprozent Knochenfett, 5,5 Gewichtsprozent Waltranfettsäure, 2,5 Gewichtsprozent Marmorkalkhydrat, 81 Gewichtsprozent Mineralöl E5o = 45. Nach 24 Stunden bei go° C sind gi Gewichtsprozent des Schmierfettes durch. das Sieb hindurchgelaufen. Die Fettstruktur des auf dem Sieb verbleibenden Fettes ist völlig zerstört.Second comparative experiment a) Lubricating grease without additive according to the invention: II weight percent bone fat, 5.5 weight percent whale oil fatty acid, 2.5 weight percent Marble lime hydrate, 81 percent by weight mineral oil E5o = 45. After 24 hours at go ° C is gi weight percent of the grease through. passed the sieve. the The fat structure of the fat remaining on the sieve is completely destroyed.
b) Schmierfett mit erfindungsgemäßem Zusatz: ii Gewichtsprozent Knochenfett, 5,5-Gewichtsprozent Waltranfettsäure, 2,5 Gewichtsprozent Marmörkalkhydrat, 79,5 Gewichtsprozent Mineralöl E5o=4,5, 1,5 Gewichtsprozent Lanocerinsäureester des Lanosterins. Nach 24 Stunden bei go° C sind 45 Gewichtsprozent des Fettes hindurchgelaufen, der Rückstand erweist sich als noch schrriierfähig.b) Lubricating fat with additive according to the invention: ii percent by weight bone fat, 5.5 percent by weight whale oil, 2.5 percent by weight marble lime hydrate, 79.5 percent by weight mineral oil E50 = 4.5, 1.5 percent by weight lanoceric acid ester of lanosterol. After 24 hours at 0 ° C, 45 percent by weight of the fat has run through, the residue proves to be still writable.
