Description

Gebiet der ErfindungField of the invention

Die Erfindung betrifft eine Schmiermittelkonzentratzusammensetzung und insbesondere eine Schmiermittelzusammensetzung, die durch Verdünnen eines solchen Konzentrats erhalten werden kann, wobei die Zusammensetzungen eine Biozidwirkung haben.The invention relates to a lubricant concentrate composition and, in particular, to a lubricant composition obtainable by diluting such a concentrate, the compositions having a biocidal effect.

Allgemeiner Stand der TechnikGeneral state of the art

Scharnierbandfördersysteme, wie sie in industriellen Flaschenwaschsystemen verwendet werden, müssen geschmiert werden, um einen gleichmäßigen Lauf zu sichern.Slat-belt conveyor systems, such as those used in industrial bottle washing systems, must be lubricated to ensure smooth running.

Auf Diaminen basierende Schmiermittel für Förderbänder sind z. B. aus EP-A-372,628 bereits bekannt. Derartige Schmiermittel verwenden Essigsäure, um die Diamine zu lösen. Dabei ist es jedoch ein Problem, daß die Schmierwirkung bei einem geringen pH-Wert verlorengeht.Diamine-based lubricants for conveyor belts are already known, for example from EP-A-372,628. Such lubricants use acetic acid to dissolve the diamines. However, the problem is that the lubricating effect is lost at a low pH value.

WO-A-92113048 offenbart antimikrobielle Schmiermittelzusammensetzungen für Förderbänder, die eine Fettsäure, eine quaternäre Ammoniumverbindung und gegebenenfalls ein Amin umfassen. WO-95/26389 stellt alkalische Gleisschmiermittel aus einem Diamin bereit, die aus einer Mischung eines Alkyldiamins und eines wasserlöslichen Hydrotropikums hergestellt werden, wobei in dieses Schmiermittel ein Biozid eingeführt ist. WO-92113050 betrifft antimikrobielle Schmiermittelzusammensetzungen für eine Fördereinrichtung, die ein Diaminacetat enthalten.WO-A-92113048 discloses antimicrobial conveyor belt lubricant compositions comprising a fatty acid, a quaternary ammonium compound and optionally an amine. WO-95/26389 provides diamine alkaline track lubricants prepared from a mixture of an alkyl diamine and a water soluble hydrotrope, in which lubricant a biocide is incorporated. WO-92113050 relates to antimicrobial conveyor lubricant compositions comprising a diamine acetate.

Die Erfinder haben festgestellt, daß durch den Austausch der Essigsäure durch eine quaternäre Ammoniumverbindung, und insbesondere Didecyldimethylammoniumchlorid, ein wirksamens Schmiermittel bereitgestellt wird. Es wurde außerdem festgestellt, daß im Vergleich mit Schmiermitteln aus dem Stand der Technik die Menge der Diaminverbindungen in der Schmiermittelzusammensetzung verringert werden kann, ohne daß die Wirksamkeit wesentlich beeinflußt wird, wodurch ein schwach schäumendes Schmiermittel bereitgestellt wird, das sich leicht wegwaschen läßt.The inventors have found that by replacing the acetic acid with a quaternary ammonium compound, and in particular didecyldimethylammonium chloride, an effective lubricant can be provided It has also been found that, compared to prior art lubricants, the amount of diamine compounds in the lubricant composition can be reduced without significantly affecting effectiveness, thereby providing a low foaming lubricant that is easily washed away.

Definition der ErfindungDefinition of the invention

Mit dieser Erfindung wird ein Verfahren zum Schmieren eines Systems, wie eines Flaschenwasch- oder Förderbandsystems, nach Anspruch 1 bereitgestellt, wobei dieses Verfahren die Schritte des Verdünnens einer Schmiermittelkonzentratzusammensetzung, wie in Anspruch 1 aufgeführt, und des Leitens des entstehenden verdünnten Schmiermittels durch das System umfaßt.This invention provides a method of lubricating a system, such as a bottle washer or conveyor system, as defined in claim 1, which method comprises the steps of diluting a lubricant concentrate composition as defined in claim 1 and passing the resulting diluted lubricant through the system.

Die verdünnte Schmiermittelzusammensetzung ist vorzugsweise eine wäßrige Lösung der erfindungsgemäßen Schmiermittelkonzentratzusammensetzung mit 0,2 bis 0,4 Gew.-%.The diluted lubricant composition is preferably an aqueous solution of the lubricant concentrate composition according to the invention at 0.2 to 0.4 wt.%.

Beschreibung der Erfindung im einzelnenDescription of the invention in detail

Da es bei den erfindungsgemäßen Schmiermittelzusammensetzungen nicht mehr notwendig ist, eine relativ große Säuremenge zuzusetzen, um die Diamine zu lösen, steht im wesentlichen das gesamte Diamin zum Schmieren zur Verfügung. Da die erfindungsgemäßen Schmiermittel im Vergleich mit bekannten Schmiermitteln stärker alkalisch sind, bieten sie somit einen Schutz vor dem Verschütten von Säure.Since the lubricant compositions according to the invention no longer require the addition of a relatively large amount of acid to dissolve the diamines, essentially all of the diamine is available for lubrication. Since the lubricants according to the invention are more alkaline than known lubricants, they therefore offer protection against acid spillage.

Ein Problem, das bei der Verwendung bekannter Schmiermittel in Scharnierbandfördersystemen auftreten kann, ist die Entstehung von Biofilmen, die, insbesondere dann, wenn die Systeme z. B. an den Wochenenden abgeschaltet werden, in diesen System wachsen und sich ausbreiten. Diese Biofilme, die von Organismen im Wasser verursacht werden, stellen die hauptsächliche Ursache für Schlamm, unangenehme Gerüche und Hygieneprobleme dar, die mit diesen Systemtypen verbunden sind. Ein weiterer Vorteil der erfindungsgemäßen Schmiermittelzusammensetzungen ist, daß sie dieses Problem der Entstehung von Biofilmen lösen, indem eine effektive Biozidwirkung bereitgestellt wird, wodurch die Bioorganismen daran gehindert werden, in dem System zu wachsen, und irgendwelche derartige Organismen, die bereits im System vorhanden sind, abgetötet werden.One problem that can occur when using known lubricants in hinged belt conveyor systems is the formation of biofilms that grow and spread in these systems, especially when the systems are shut down, for example on weekends. These biofilms, which are caused by organisms in the water, represent the is the main cause of sludge, unpleasant odors and hygiene problems associated with these types of systems. A further advantage of the lubricant compositions of the invention is that they solve this problem of biofilm formation by providing an effective biocidal action, thereby preventing the bioorganisms from growing in the system and killing any such organisms already present in the system.

Die im erfindungsgemäßen Verfahren verwendete Schmiermittelkonzentratzusammensetzung umfaßt vorzugweise 1 bis 5 Gew.-% jeder darin vorhandenen Diaminverbindung. Stärker bevorzugt liegt die Konzentration jeder Diaminverbindung im Bereich von 1 bis 2 Gew.-%. Die in der erfindungsgemäßen Schmiermittelzusammensetzung vorhandenen Diaminverbindungen sind aus der Gruppe ausgewählt, die im wesentlichen aus N- Oleyl-1,3-diaminopropan und N-Coco-1,3-diaminopropan besteht, wobei diese wirksame Ergebnisse erzielen.The lubricant concentrate composition used in the process of the present invention preferably comprises from 1 to 5% by weight of each diamine compound present therein. More preferably, the concentration of each diamine compound is in the range of from 1 to 2% by weight. The diamine compounds present in the lubricant composition of the present invention are selected from the group consisting essentially of N-oleyl-1,3-diaminopropane and N-coco-1,3-diaminopropane, which produce effective results.

Die Konzentration der quaternären Ammoniumverbindung, die in der Schmiermittelkonzentratzusammensetzung vorhanden ist, liegt im Bereich von 4 bis 10 Gew.-%, vorzugsweise von 5 bis 6 Gew.-%. Die quaternäre Ammoniumverbindung ist Didecyldimethylammioniumchlorid. Didecyldimethylammioniumchlorid bietet folgende Vorteile:The concentration of the quaternary ammonium compound present in the lubricant concentrate composition is in the range of 4 to 10 wt.%, preferably 5 to 6 wt.%. The quaternary ammonium compound is didecyldimethylammionium chloride. Didecyldimethylammionium chloride offers the following advantages:

- Der pH-Bereich, in dem sowohl eine Schmierung als auch eine Desinfektion (Biozidwirkung) erreicht werden, wenn diese quaternäre Ammoniumverbindung in der erfindungsgemäßen Zusammensetzung verwendet wird, ist größer als der, der mit bekannten herkömmlichen Schmiermitteln - wie jenen, die in EP-A-372,628 offenbart sind - erreicht wird, wobei die Obergrenze des pH-Wertes nach der vorliegenden Erfindung etwa 10 beträgt;- the pH range in which both lubrication and disinfection (biocidal effect) are achieved when this quaternary ammonium compound is used in the composition according to the invention is greater than that achieved with known conventional lubricants - such as those disclosed in EP-A-372,628 - the upper limit of the pH according to the present invention being about 10;

- die Empfindlichkeit gegenüber Anionen in Verdünnungswasser ist im Verhältnis zu bekannten Schmiermitteln wesentlich geringer, mit anderen Worten haben die Erfinder eine beträchtliche Verbesserung auf dem Gebiet von auf Diaminen basierenden Schmiermitteln gefunden, die bekanntlich für die Fällung aus Anwendungslösungen empfindlich sind, die hohe Werte von Anionen, insbesondere Sulfaten, enthalten;- the sensitivity to anions in dilution water is significantly lower in relation to known lubricants, in other words, the inventors have found a considerable improvement in the field of diamine-based lubricants, which are known to be sensitive to precipitation from application solutions containing high levels of anions, in particular sulfates;

- der chemische Bedarf an Sauerstoff und die Stickstoffwerte der erfindungsgemäßen Zusammensetzungen, die diesen Typ einer quaternären Ammoniumverbindung enthalten, sind geringer, wodurch die Umweltbelastung und die Kosten für die Abwasserbehandlung geringer werden;- the chemical oxygen demand and the nitrogen levels of the compositions according to the invention containing this type of quaternary ammonium compound are lower, thereby reducing the environmental impact and the costs of waste water treatment;

- der Schaumwert ist im Vergleich mit bekannten Schmiermitteln wesentlich geringer, wodurch der Schaum leicht weggespült werden kann und die erfindungsgemäßen Schmiermittelzusammensetzungen kostengünstig sind.- the foam value is significantly lower compared to known lubricants, which means that the foam can be easily washed away and the lubricant compositions according to the invention are cost-effective.

Die erfindungsgemäße Schmiermittelzusammensetzung umfaßt außerdem vorzugsweise eine Säure, wünschenswerterweise Essigsäure. Die Konzentration dieser Säure in der Konzentratzusammensetzung liegt wirksam im Bereich von 0,01 bis 1 Gew.-%.The lubricant composition of the invention further preferably comprises an acid, desirably acetic acid. The concentration of this acid in the concentrate composition is effectively in the range of 0.01 to 1% by weight.

Um die Detergenz der erfindungsgemäßen Schmiermittelzusammensetzung zu verbessern, umfaßt die Zusammensetzung außerdem vorzugsweise ein nichtionisches Mittel, wobei dessen Konzentration wirksam im Bereich von 0,1 bis 5 Gew.-%, bezogen auf die Konzentratzusammensetzung, liegt. Dieses nichtionische Mittel ist vorzugsweise Oleylaminethoxylat.In order to improve the detergency of the lubricant composition of the invention, the composition preferably further comprises a nonionic agent, the concentration of which is effectively in the range of 0.1 to 5% by weight of the concentrate composition. This nonionic agent is preferably oleylamine ethoxylate.

Eine weitere wahlfreie und bevorzugte Komponente der Schmiermittelzusammensetzung ist eine Gerüstsubstanz, die vorzugsweise Triethanolamin ist. Die Konzentration dieser Gerüstsubstanz liegt vorzugsweise im Bereich von 0,1 bis 5 Gew.-%, bezogen auf die Konzentratzusammensetzung.Another optional and preferred component of the lubricant composition is a builder substance, which is preferably triethanolamine. The concentration of this builder substance is preferably in the range of 0.1 to 5% by weight based on the concentrate composition.

Die vorliegende Erfindung wird anhand des nachstehenden Beispiels erläutert, worin % auf das Gewicht bezogen ist, wenn es nicht anders angegeben ist.The present invention is illustrated by the following example, where % is by weight unless otherwise stated.

Es wurde ein Schmiermittelkonzentrat mit der folgenden Zusammensetzung formuliert:A lubricant concentrate was formulated with the following composition:

Gew.-%% by weight

N-Oleyl-1,3-diaminopropan 1,5N-Oleyl-1,3-diaminopropane 1,5

N-Coco-1,3-diaminopropan 1,5N-Coco-1,3-diaminopropane 1,5

Essigsäure (60%) (andere Säuren) 0,5Acetic acid (60%) (other acids) 0.5

Didecyldimethylammoniumchlorid (80%) 6,8Didecyldimethylammonium chloride (80%) 6.8

Wasser bis auf 100,0Water up to 100.0

Diese Konzentratzusammensetzung wurde mit Wasser zu einer verdünnten Schmiermittelzusammensetzung mit 0,3 Gew.-% verdünnt. Es ist selbstverständlich, daß der erforderliche Verdünnungsgrad, um eine geeignet verdünnte Schmiermittelzusammensetzung zu erhalten, von der Konzentration der Diamine in der Konzentratzusammensetzung abhängt.This concentrate composition was diluted with water to give a 0.3% by weight diluted lubricant composition. It is to be understood that the degree of dilution required to obtain a suitably diluted lubricant composition will depend on the concentration of diamines in the concentrate composition.
