Als nachteilig hat sich bei den bekannten Schmiermitteln u.a. herausgestellt, daß die Schmierwirkung in der Praxis oftmals nicht ausreichend ist, d.h. daß die Reinigungswirkung im betrieblichen Einsatz häufig Mängel aufweist, daß z.T. mit überhöhten Konzentrationen an Schmiermitteln gearbeitet werden muß und daß Gleitmittellösungen herkömmlichen Typs im Leitungs- und Dosiersystem Ablagerungen verursachen können. Letztere können zu Verstopfungen der in der Regel automatisch arbeitenden Schmiermittelvorrichtung führen, was zur Folge hat, daß der Betrieb der automatischen Flaschentransportanlagen gestört wird. Dies tritt insbesondere nach Unterbrechungen des Betriebes, vor allem nach Wochenenden, auf.A disadvantage of the known lubricants has been pointed out that the lubricating effect is often not sufficient in practice, i.e. that the Cleaning effect in operational use often has defects that in some cases With excessive concentrations of lubricants must be worked and that Lubricant solutions of conventional types in the line and dosing system can cause. The latter can usually lead to constipation automatically working lubricant device, which results in that the operation of the automatic bottle transport systems is disrupted. This occurs especially after business interruptions, especially after weekends, on.

Ein bevorzugtes Schmiermittel weist folgende Zusammensetzungen auf: (Gew.-%) Milchsäure (80%ig) 2-10 N-Oleyl-1,3-diaminopropan 3-15 N-Lauryl-1,3-diaminopropan 0,5-4,5 Alkyl(C16-C18)polyethylenglykolether(9EO)-essigsäure 0,5-4,5 Alkyl(C13)-polyethylenglykolether (6 Mol EO) 0,5-3,0 Alkyl(C13)-polyethylenglykolether (12 Mol EO) 0,5-3,0 Rest Wasser (destilliert, enthärtet) A preferred lubricant has the following compositions: (% By weight) Lactic acid (80%) 2-10 N-oleyl-1,3-diaminopropane 3-15 N-lauryl-1,3-diaminopropane 0.5-4.5 Alkyl (C 16 -C 18 ) polyethylene glycol ether (9EO) acetic acid 0.5-4.5 Alkyl (C 13 ) polyethylene glycol ether (6 mol EO) 0.5-3.0 Alkyl (C 13 ) polyethylene glycol ether (12 mol EO) 0.5-3.0 Rest of water (distilled, softened)

Die Schmiermittelzusammensetzung kann auch Hilfs- und/oder Zusatzstoffe enthalten. In Betracht kommen hierbei insbesondere Lösungsvermittler wie Alkohole, Polyalkohole, Ether oder Polyether, insbesondere Isopropanol, Butylglykol, Butyldiglykol oder Ethylenglykolether. Die Menge des zu verwendenden Lösungsvermittlers hängt im allgemeinen von dem eingesetzten Amin ab.The lubricant composition can also contain auxiliaries and / or additives contain. Solubilizers such as Alcohols, polyalcohols, ethers or polyethers, in particular isopropanol, butylglycol, Butyl diglycol or ethylene glycol ether. The amount of to use Solubilizer generally depends on the amine used.

Der pH-Wert der einsatzbereiten Schmiermittel liegt bevorzugt zwischen etwa 6,5 und 7,0.The pH value of the ready-to-use lubricants is preferably between about 6.5 and 7.0.

Bei der Anwendung der oben beschriebenen Bandschmiermittel können verschiedene Probleme entstehen, welche bis heute nicht oder nur teilweise gelöst worden sind:

  • Eine hohe Empfindlichkeit gegenüber verschiedenen Ionen, welche sich im Betriebswasser befinden können, wie z.B. Carbonat- und Hydrogencarbonationen, Sulfat- und Erdalkalimetallionen, welche Ausfällungen verursachen können. Dadurch können Ausfällungen oder Trübungen stattfinden, welche zur Verstopfung der Sprühdüsen führen können.
  • Eine ungenügende biozide Wirkung, so daß die Transportbänder von Mikroorganismen befallen werden können.
  • Eine zu starke biozide Wirkung mit der Gefahr, daß die angeschlossenen Kläranlagen in ihrer Funktion gestört werden.
  • Eine zu starke Schaumentwicklung, welche die Flaschenkontrolle an den Lichtschranken stört.
Various problems can arise when using the belt lubricants described above, which have not or only partially been solved to date:
  • A high sensitivity to various ions that can be in the process water, such as carbonate and hydrogen carbonate ions, sulfate and alkaline earth metal ions, which can cause precipitation. This can result in precipitation or clouding, which can lead to blockage of the spray nozzles.
  • An insufficient biocidal effect, so that the conveyor belts can be infected by microorganisms.
  • Too strong a biocidal effect with the risk that the connected sewage treatment plants will be disturbed in their function.
  • Excessive foaming, which disrupts bottle inspection at the light barriers.

Die Aufgabe der Erfindung bestand nun darin, eine neue Schmiermittelzubereitung, insbesondere als Kettengleitmittel, bereitzustellen, das die Nachteile des oben genannten Standes der Technik nicht aufweist, d.h. derartige Schmiermittel sollen sowohl eine guten Reibwert, also eine ausgezeichnete Schmierwirkung, ein geringes Schaumverhalten, eine gute Reinigungswirkung und eine gute Mikrobiozidwirkung aufweisen.The object of the invention was now to provide a new lubricant preparation, in particular as a chain lubricant, to provide the disadvantages of above-mentioned prior art, i.e. such lubricants should have a good coefficient of friction, i.e. an excellent lubricating effect, a low foaming behavior, a good cleaning effect and a good one Have microbicidal activity.

Die Aufgabe wird durch das erfindungsgemäße Schmiermittel gemäß Anspruch 1, das mindestens ein sekundäres Amin der Formel I und/oder mindestens ein Salz eines derartigen Amins und/oder mindestens ein Amid der Formeln II und/oder III bzw. deren Salze enthält, gelöst.The object is achieved by the lubricant according to the invention 1, the at least one secondary amine of formula I and / or at least one Salt of such an amine and / or at least one amide of the formula II and / or III or their salts.

Überraschenderweise zeigen die erfindungsgemäßen Schmiermittel nicht die Nachteile, die mit den Schmiermitteln auf Basis primärer Fettamine verbunden sind. Dies ist um so unerwarteter, als schon geringe Mengen der sekundären Amine gemäß der Formel I bzw. deren Salze eine hervorragende Gleitwirkung besitzen.Surprisingly, the lubricants according to the invention do not show that Disadvantages associated with the lubricants based on primary fatty amines are. This is all the more unexpected than even small amounts of the secondary Amines according to formula I or their salts have an excellent lubricating effect have.

Weiterhin war zudem überraschend, daß auch das Schmiermittel auf Basis mindestens eines Amids der Formel II und/oder der Formel III schon in geringen Mengen, d.h. bei 50 bis 100 ppm eine hervorragende Gleitwirkung besitzt.Furthermore, it was also surprising that the lubricant was also based at least one amide of the formula II and / or the formula III even in small amounts Quantities, i.e. at 50 to 100 ppm has an excellent sliding effect.

eine Polyglykoletherkette -[(CH2)n-O]m- ist, die durch Anlagerung von 2 bis 20 Mol (m = 2 bis 20) Ethylen- und/oder Propylenglykol (n = 2 oder 3) entsteht. Die Länge einer Polyethylenglykolkette kann auch durch die Anzahl der von Ethylenoxid (EO) ableitbaren Einheiten charakterisiert werden, so daß z.B. im Fall von 9 Ethylenglykoleinheiten (m = 9) die Schreibweise "9EO" üblich ist. Die Polyglykoletherkette kann ferner unsubstituiert oder substituiert sein, und kann insbesondere mit folgenden Gruppen substituiert sein: -PO3H2, -SO3H, -Aryl.

is a polyglycol ether chain - [(CH 2 ) n -O] m -, which is formed by the addition of 2 to 20 mol (m = 2 to 20) ethylene and / or propylene glycol (n = 2 or 3). The length of a polyethylene glycol chain can also be characterized by the number of units that can be derived from ethylene oxide (EO), so that, for example, in the case of 9 ethylene glycol units (m = 9) the notation “9EO” is common. The polyglycol ether chain can also be unsubstituted or substituted, and can in particular be substituted with the following groups: -PO 3 H 2 , -SO 3 H, -aryl.

Aminopolyglykolether werden von verschiedenen Herstellern angeboten, z.B. Marlazin-Typen von Hüls AG, Genamin-Typen von HOECHST AG; Ethomeen-Marken von AKZO. Sie werden hauptsächlich als Emulgatoren und als Korrosionsinhibitoren eingesetzt. Diese Handelsprodukte bestehen jedoch hauptsächlich (in einigen Fällen ausschließlich) aus tertiären Aminen. Die Bildung der sekundären Isomere wird durch geeignete Maßnahmen soweit wie möglich unterbunden, weil sie für die bekannten industriellen Anwendungen dieser Gruppe von Produkten unerwünscht bzw. weniger leistungsfähig als die entsprechenden tertiären Aminopolyglykolether sind.Aminopolyglycol ethers are offered by various manufacturers, e.g. Marlazin types from Hüls AG, genamine types from HOECHST AG; Ethomeen brands by AKZO. They are mainly used as emulsifiers and as corrosion inhibitors used. However, these commercial products mainly exist (in some cases exclusively) from tertiary amines. The formation of the Secondary isomers are avoided by appropriate measures as far as possible prevented because they are for the known industrial applications of this Group of products undesirable or less powerful than the corresponding ones are tertiary aminopolyglycol ethers.

AKZO, bezeichnet ETHOMEEN S/12, ein sehr wichtiges Produkt aus der Gamme der Fettaminethoxylate, eindeutig als "Oleylalkyldi(2-hydroxyethyl)amin" (ein tertiäres Amin), CAS-Nr. 25307-17-9. In den entsprechenden Unterlagen wird der Anteil an primären und sekundären Aminen darin ausdrücklich mit < 3% angegeben. Eine Analyse von einer repräsentativen Anzahl von Mustern von verschiedenen Fettaminethoxylaten aus heutiger Produktion und von verschiedenen Herstellern hat ähnliche Werte ergeben.AKZO, called ETHOMEEN S / 12, a very important product from the Gamme the fatty amine ethoxylates, clearly as "oleylalkyldi (2-hydroxyethyl) amine" (a tertiary amine), CAS no. 25307-17-9. In the relevant documents the proportion of primary and secondary amines therein expressly with <3% specified. An analysis of a representative number of patterns from various fatty amine ethoxylates from today's production and from various Manufacturers have given similar values.

EP 0 372 628 B1 erwähnt tertiäre Fettaminpolyglykolether als geeignete Additive (Dispergatoren) in Bandschmiermitteln. Die entsprechenden sekundären Aminopolyglykolether werden dagegen nicht erwähnt. EP 0 372 628 B1 mentions tertiary fatty amine polyglycol ethers as suitable additives (Dispersants) in belt lubricants. The corresponding secondary aminopolyglycol ethers are not mentioned.

    Aus der Praxis ist bekannt, daß Reibungskoeffizienten von ≤ 0,16 für den Betrieb von Hochleistungsflaschentransportbändern ausreichend sind.From practice it is known that friction coefficients of ≤ 0.16 for the Operation of high-performance bottle conveyor belts are sufficient.

    Die erfindungsgemäßen Beispiele zeigen deshalb, daß Amine der allgemeinen Formel I und/oder Amide der allgemeinen Formeln II und III schon in Konzentrationen von nur 50 ppm eine ausreichende Wirkung bei optimalem Schaumverhalten aufweisen. Die erfindungsgemäßen Amine bzw. Amide sind zudem wasserhärteunempfindlich, sowohl bezüglich Wirksamkeit als auch Löslichkeit und Schaumverhalten.The examples according to the invention therefore show that amines of the general Formula I and / or amides of the general formulas II and III already in concentrations A sufficient effect of only 50 ppm with optimal foaming behavior exhibit. The amines or amides according to the invention are also Insensitive to water hardness, both in terms of effectiveness and solubility and foaming behavior.

    Die aufgeführten, handelsüblichen Schmiermittel (Vergleichsversuche 1 bis 4) wirken dagegen erst ab einer Konzentration von 150 ppm und nur bei Weichwasser (z.B. Vergl.-Bsp. 2A, Reibungskoeffizient 0,14).The listed, commercially available lubricants (comparative tests 1 to 4) on the other hand, only work from a concentration of 150 ppm and only with soft water (e.g. Comp. Ex. 2A, coefficient of friction 0.14).

    Die Schmierwirkung von Aminen gemäß DE 43 15 271 A1 (Vergl.-Bsp. 5 und 6) in einer Konzentration von 50 ppm ist zwar besser als diejenige der in den anderen Vergleichsbeispielen verwendeten Formulierungen derselben Konzentration (Vergleichsbeispiele 8A-8B und 9A-9B. Reibungskoeffizienten = 0,55 - 0,35), allerdings reichen derartige Amine für die Anwendung auf Hochleistungsförderbändern (Reibungskoeffizient = 0,30) in dieser Konzentration nicht aus.The lubricating effect of amines according to DE 43 15 271 A1 (comp. Ex. 5 and 6) in a concentration of 50 ppm is better than that in the other comparative examples used formulations of the same concentration (Comparative Examples 8A-8B and 9A-9B. Coefficients of friction = 0.55 - 0.35), but such amines are sufficient for use on high-performance conveyor belts (Coefficient of friction = 0.30) in this concentration.
