Description

SCHMIERSTOFFE AUF WASSERBASIS FÜR FÖRDERBÄNDER  WATER-BASED LUBRICANTS FOR CONVEYOR BELTS
Beschreibung description
Die Erfindung betrifft Schmierstoffe auf Wasserbasis für Förderbänder. Insbesondere betrifft die Erfindung Schmierstoffe auf Wasserbasis für Förderbänder für die Getränkeindustrie. Schmierstoffe für Förderbänder für die Getränkeindustrie müssen hohen Anforderungen, insbesondere hinsichtlich ihrer Lebensmitteltauglichkeit und -Verträglichkeit genügen. Zur Schmierung von Förderbändern in Abfüllstraßen der Getränkeindustrie werden, je nach Applikationstechnologie, entweder Schmieröle eingesetzt oder Emulsionen/Dispersionen, die mit Wasser unterschiedlich stark verdünnt werden. Die WO 2007/040678 A1 beschreibt ein solches Konzept. Es handelt sich dabei um eine Silikonemulsion, die mit Wasser verdünnt wird. Je nach Verdünnungsgrad spricht man dann von einer „wet"- oder „semidry"-Schmierung. Im Falle einer „wet"-Schmierung mit typischen Verdünnungen des Schmierstoffes von 1 :100 bis 1 :1000 ist der Wasserverbrauch sehr hoch. Bei einer Verdünnung kleiner 1 :100 spricht man von„semidry"-Schmierung. In beiden Fällen ist zu beachten, dass die Härte des zugesetzten Wassers entscheidenden Einfluss auf die Performance und Verträglichkeit des Schmierstoffes mit dem transportierten Verpackungsmaterial nimmt. Entsprechend müssen einem „wet"- oder „semidry' -Schmierstoff typischerweise erhöhte Mengen an freien organischen Säuren zugesetzt werden, um die Wasserhärte-bedingte Alkalität zu neutralisieren. Nachteilig an Emulsionen bzw. Suspensionen ist jedoch, dass häufig Rühraggregate beim Abmischen mit Wasser erforderlich sind und sie eine schlechtere Lagerstabilität als homogene Lösungen aufweisen. Außerdem ist es nicht möglich, einen geschlossenen Film der schmieraktiven Komponente auf die Transportkette zu realisieren, was sich nachteilig auf die tribologischen Eigenschaften auswirkt. Allen genannten Schmierstoffen gemein ist die relativ aufwendige Reinigung der Förderbänder. The invention relates to water-based lubricants for conveyor belts. In particular, the invention relates to water-based lubricants for conveyor belts for the beverage industry. Lubricants for conveyor belts for the beverage industry must meet high requirements, in particular with regard to their suitability for food and tolerability. For lubrication of conveyor belts in bottling lines of the beverage industry, either lubricating oils are used or emulsions / dispersions, which are diluted to varying degrees with water, depending on the application technology. WO 2007/040678 A1 describes such a concept. It is a silicone emulsion that is diluted with water. Depending on the degree of dilution one then speaks of a "wet" or "semidry" lubrication. In the case of a "wet" lubrication with typical dilutions of the lubricant from 1: 100 to 1: 1000, the water consumption is very high, at a dilution of less than 1: 100 it is called "semidry" lubrication. In both cases, it should be noted that the hardness of the added water has a decisive influence on the performance and compatibility of the lubricant with the transported packaging material takes. Accordingly, a "wet" or "semidry" lubricant typically needs to be supplemented with increased amounts of free organic acids in order to neutralize the water-hardness-related alkalinity However, it is a disadvantage of emulsions or suspensions that stirring aggregates are frequently required when mixed with water Moreover, it is not possible to realize a closed film of the lubricant-active component on the transport chain, which has a negative effect on the tribological properties.
Ein Ziel der vorliegenden Erfindung war es daher, eine tribologisch hochwirksame Schmierstoffformulierung bereitzustellen, die in Kleinstmengen wirksam ist und nicht weiter mit Wasser verdünnt werden muss. Damit ist ein Maximum an Wasserersparnis möglich. Darüber hinaus ist die erfindungsgemäße Formulierung biologisch abbaubar und im Lebensmittelbereich anwendbar. Die Formulierung ist des weiteren lagerstabil, in Wasser vollständig löslich und leicht von den Förderbändern zu entfernen. Diese Ziele werden durch die Bereitstellung einer wasserbasierten Schmierstoffzusammensetzung erreicht, die einen Wasseranteil von 50 bis 96 Gew.-%, 4 bis 40 Gew.-% mindestens eine viskositätsgebende Komponente und 0,05 bis 10 Gew.-% konservierende, vor Verschmutzung schützende Substanzen umfasst. Es sind keine Feststoffe und keine wasserunlöslichen Komponenten vorhanden. An object of the present invention was therefore to provide a tribologically highly effective lubricant formulation which is effective in very small amounts and does not need to be further diluted with water. Thus, a maximum of water savings is possible. In addition, the formulation of the invention is biodegradable and applicable in the food industry. The formulation is also storage stable, completely soluble in water and easy to remove from the conveyor belts. These objects are achieved by providing a water-based lubricant composition having a water content of 50 to 96% by weight, 4 to 40% by weight of at least one viscosity-providing component and 0.05 to 10% by weight of preservative, anti-pollution substances includes.

1. Verschleißschutz  1. Wear protection
Die SRV-Prüfung (Schwing-Reib-Verschleiß) ist eine gebräuchliche Prüfung zur Quantifizierung der Verschleißschutzwirkung von Schmierstoffen. Dies wird üblicherweise an der Materialpaarung Stahl - Stahl durchgeführt. Im 0 vorliegenden Fall wurde zur besseren Übertragbarkeit auf die Anwendung die Materialpaarung POM (Polyoxymethylen) - Stahl gewählt. Ausgewertet wurde die Verschleißrate nach einer Versuchsdauer von 6 Stunden bei einer Belastung von 95 N/mm2. The SRV test (vibration-friction-wear) is a common test for quantifying the wear protection effect of lubricants. This is usually done on the material pairing steel - steel. In the present case, the material pairing POM (polyoxymethylene) steel was chosen for better transferability to the application. The wear rate was evaluated after a test period of 6 hours at a load of 95 N / mm 2 .

Example 2 0.10 Table 1 shows that all three examples according to the present invention have significantly lower wear rates than commonly used products.
2. Spreitverhalten 2. Spreading behavior
Ein gutes Spreitverhalten ist im Falle von Minimalmengenschmierung zur Aufrechterhaltung eines durchgehenden Schmierfilmes unerlässlich. Das Spreitverhalten wird üblicherweise bestimmt im Rahmen von Kontaktwinkelmessungen auf der relevanten Oberfläche. Je niedriger der Kontaktwinkel, desto besser ist die Benetzung der Oberfläche. Good spreading behavior is essential in the case of minimum quantity lubrication for maintaining a continuous lubricating film. The spreading behavior is usually determined in the context of contact angle measurements on the relevant surface. The lower the contact angle, the better the wetting of the surface.
Tabelle 2 Table 2
Tabelle 2 zeigt, dass die Beispiele der vorliegenden Erfindung ein signifikant besseres Spreitverhalten als das häufig verwendete Wetlube Lubostar CP auf weisen. Die Untersuchungen wurden auf PBT, als häufig verwendetes Kettenmaterial, durchgeführt. 3. Prüfungen auf Fördervorrichtungen verschiedene Paarungen Table 2 shows that the examples of the present invention have significantly better spreading performance than the commonly used Wetlube Lubostar CP. The investigations were carried out on PBT, as a commonly used chain material. 3. Tests on conveyors different pairings
Die Überprüfung der Schmierperformance der wasserbasierten Beispielformulierung erfolgte an einem Standardfördervorrichtung der Firma Krones unter Verwendung verschiedener relevanter Materialkombinationen bei Raumtemperatur und einer typischen Kettengeschwindigkeit von 0,8 m/sec. Die Reibzahlen wurden jeweils an einer originalverschlossenen 1 I Glas- Wasserflasche, einer 1 ,5 I PET Einwegflasche und einem 1 ,5 I TetraPack ermittelt. Die auf der Förderkette1 schleifenden Gebinde wurden mit einer Schnur an einer Federwaage fixiert. The check of the lubricity performance of the water-based example formulation was carried out on a standard Krones conveyor using various relevant material combinations at room temperature and a typical chain speed of 0.8 m / sec. The Friction numbers were determined on an original sealed 1 l glass water bottle, a 1, 5 l PET disposable bottle and a 1, 5 l TetraPack. The sanding on the conveyor chain 1 containers were fixed with a string on a spring balance.
Tabelle 3 Table 3
Üblicherweise sollen die Reibzahlen der verschiedenen Materialpaarungen im Bereich 0,05 bis 0,20 liegen. Tabelle 3 zeigt die gute Schmierwirkung der untersuchten Zusammensetzungen. Usually, the friction coefficients of the different material pairings should be in the range of 0.05 to 0.20. Table 3 shows the good lubricity of the compositions tested.
Mit der Schmierstoffzusammensetzung gemäß Beispiel 3 wurde zum Beleg der exzellenten Leistungsfähigkeit bei minimalstem Schmierstoffverbrauch eine 1 ,5 I PET Einweg Flasche über einen Zeitraum von 4 Stunden unter den oben beschriebenen Bedingungen geprüft. Dabei wurde alle 5 Minuten mit 0,05 ml Schmierstoff nachgeschmiert. Der Reibwert bewegte sich dabei durchgehend bei 0,09+/-0,01 und liegt somit im Idealbereich für diese Materialpaarung. With the lubricant composition of Example 3, to demonstrate excellent performance with minimal lubricant consumption, a 1.5 I PET disposable bottle was tested over a period of 4 hours under the conditions described above. It was relubricated with 0.05 ml of lubricant every 5 minutes. The coefficient of friction was continuously 0.09 +/- 0.01 and is therefore within the ideal range for this combination of materials.
4. Korrosionsschutz 4. Corrosion protection
Bei der Verwendung von wasserbasierten Schmierstoffen anstelle eines ölbasierten Trockenschmiermittel ist ein ausreichender Korrosionsschutz der Applikationstechnik sicherzustellen, um Bauteile, wie Zumess-Ventile oder Sprühventile, zu schützen. Typische Korrosionsschutzprüfungen erfolgen durch Einlagerung relevanter Bauteile in die Schmierstoffformulierung bei erhöhter Temperatur. Tabelle 4 When using water-based lubricants instead of an oil-based dry lubricant, ensure sufficient corrosion protection of the application technology to protect components such as Zumess valves or spray valves. Typical corrosion protection tests are carried out by incorporating relevant components into the lubricant formulation at elevated temperature. Table 4

Verunreinigungen an Lebensmittelgebinden sind aus hygienischen und kosmetischen Gründen unbedingt zu vermeiden. Typische Verunreinigungen sind normale Stäube, Partikel von Verpackungen, ausgelaufenes Lebensmittel, Verschleißpartikel von Kette und Gleitleiste, sowie Schmierstoffrückstände.

(Drylube wasserbasiert) Herstellers ungenügend An den in Tabelle 5 genannten Schmiermitteln wurden sowohl im laufenden Betrieb als auch bei Laboruntersuchungen an einer Original-PBT-Kette am Testconveyor der Aufbau von Verschmutzungen durchgeführt. Überraschenderweise wurde an Beispiel 3 eine signifikante Reduzierung des Rückstandaufbaus erzielt. (Drylube water-based) manufacturer insufficient On the lubricants listed in Table 5, the build-up of soiling was carried out both on the fly and during laboratory tests on an original PBT chain on the test conveyor. Surprisingly, a significant reduction of the residue structure was achieved in Example 3.
7. Entschäumer 7. Defoamer
Eine zu starke Schaumentwicklung bei der Applikation von Conveyor- Schmierstoffen sollte aufgrund einer reduzierten tribologischen Wirksamkeit vermieden werden. Auch lassen sich schaumbildende Schmierstoffe schlechter applizieren, vor allem bei der Verwendung von Sprühdüsen. Die Verwendung eines Entschäumers in Beispielformulierung 5 zeigte visuell eine signifikante Verringerung der Schaumneigung. Too much foaming during the application of Conveyor lubricants should be avoided due to a reduced tribological effectiveness. Foaming lubricants can also be applied worse, especially when using spray nozzles. The use of a defoamer in Example Formulation 5 visually showed a significant reduction in foaming tendency.
Tabelle 7 Table 7
8. Klarheit 8. Clarity
Sämtliche Formulierungen der Beispiele 1 bis 6 sind klare Lösungen. Durch die Homogenität des Systems ergeben sich deutliche Vorteile bei der Lager- und Transportstabilität, der gleichmäßigen Applizierbarkeit ohne Verwendung von Rühraggregaten, sowie einer Vermeidung von wasserunlöslichen Rückständen auf der Förderkette im Falle von Emulsionen / Suspensionen. Tabelle 8 All formulations of Examples 1 to 6 are clear solutions. Due to the homogeneity of the system, there are clear advantages in terms of storage and transport stability, uniform applicability without the use of stirrers, and avoidance of water-insoluble residues on the conveyor chain in the case of emulsions / suspensions. Table 8
9. Abduschung mit Wasser 9. Abduschung with water
Die Reinigung von Förderketten erfordert üblicherweise einen Produktionsstillstand, da das Reibverhalten stark von der beauftragten Wassermenge beeinflusst wird und typischerweise im Falle von erhöhter Feuchtigkeit verschlechtert wird. Auch kann nicht ausgeschlossen werden, dass transportierte Wasserflaschen zerplatzen und dies zu einer örtlich begrenzten Abduschung des Schmiermittels von der Förderkette führt. Tabelle 9 The cleaning of conveyor chains usually requires a production stoppage because the frictional behavior is strongly influenced by the amount of water ordered and is typically worsened in the case of increased humidity. Also, it can not be ruled out that transported water bottles burst and this leads to a localized Abduschung the lubricant from the conveyor chain. Table 9
Überraschenderweise wurde gefunden, dass die Formulierung gemäß Beispiel 2 selbst bei Abduschung mit der 500fachen Wassermenge im Vergleich zu der auf die Kette aufgebrachten Schmierstoffmenge nur zu einer mäßigen Verschlechterung der Reibzahl von 35% führt. Dies ermöglicht den ununterbrochenen Abfüllbetrieb im Fall von Störungen oder bei der Reinigung, was im Vergleich mit einer bekannten Schmiermittelzusammensetzung nicht der Fall war, da hier die Reibzahl um 75% verschlechtert wurde. Surprisingly, it has been found that the formulation according to Example 2, even at Abkuschung with 500 times the amount of water compared to the applied lubricant to the chain only leads to a moderate deterioration of the friction coefficient of 35%. This enables the uninterrupted filling operation in the event of malfunctions or in the cleaning, which was not the case in comparison with a known lubricant composition, since the coefficient of friction was deteriorated by 75%.
10. Applizierbarkeit Die Schmierstoffzusammensetzung gemäß Beispiel 5 konnte sowohl mittels Dosierung über Zumessventil oder Magnetventil und anschließendem Auftrag mittels Gleitplatte als auch über druckluftbetriebene oder druckluftlosbetriebene Düsen appliziert werden. Insbesondere die Möglichkeit, dass die Zusammensetzung gemäß Beispiel 4 in minimalen Mengen mittels druckluftloser Düsen appliziert werden kann, unterscheidet diese Formulierung von häufig verwendeten Standardprodukten, wie z.B. DryExx SF oder P3 Lubodrive RF. 10. Applicability The lubricant composition according to Example 5 could be applied by means of metering via metering valve or solenoid valve and subsequent application by means of a sliding plate as well as via compressed air-operated or compressed air-operated nozzles. In particular, the possibility that the composition according to Example 4 can be applied in minimal quantities by means of airless nozzles distinguishes this formulation from commonly used standard products, such as e.g. DryExx SF or P3 Lubodrive RF.
11. Kompatibilität mit Verpackungen, Applikationstechnik und Kettenmaterial 11. Compatibility with packaging, application technology and chain material
Zur weiteren Überprüfung der Eigenschaften der Schmiermittelzusammensetzungen der vorliegenden Erfindung wurden Einlagerungstests an Dichtungsmaterial, Schlauchmaterial, Rohrelementen, Düsenbestandteilen, Pumpenmembranen und Magnetventilen gängiger Applikationstechnik und POM-Kettenmaterial bei 70°C über 4 Wochen mit Beispielformulierung 5 durchgeführt. Es wurden keine Materialveränderungen festgestellt. To further verify the properties of the lubricating compositions of the present invention, incorporation tests on sealing material, tubing, tubing, nozzle components, pump diaphragms and common application solenoid valves and POM chain material were carried out at 70 ° C for 4 weeks Example formulation 5 carried out. No material changes were detected.
Für die Gebindekompatibilität wurden original gefüllte 1 ,5 I PET Einwegflaschen, 1 I Glasflaschen, 0,5 I Dose und 0,5 I TetraPack für 30 sec auf eine mit Formulierung gemäß Beispiel 5 benetzte Glasoberfläche gestellt und anschließend für 72 Stunden auf einer sauberen Glasoberfläche gelagert. Dann wurde visuell auf Materialveränderung, wie Stress, Cracking oder Verfärbungen, untersucht. In keinem Fall wurden Auffälligkeiten beobachtet. 2. Biologische Abbaubarkeit For the package compatibility, originally filled 1.5 l PET disposable bottles, 1 l glass bottles, 0.5 l tin and 0.5 l TetraPack were placed on a glass surface wetted with the formulation according to Example 5 and then placed on a clean glass surface for 72 hours stored. Then was visually examined for material change, such as stress, cracking or discoloration. In no case abnormalities were observed. 2. Biodegradability
Sämtliche genannte Beispielformulierungen sind durch den hohen Wassergehalt, sowie durch die sehr gute biologische Abbaubarkeit der verwendeten Viskositätsgeber im hohen Maße umweltverträglich und biologisch abbaubar. All of the example formulations mentioned are due to the high water content, as well as by the very good biodegradability of the viscosity generator used highly environmentally friendly and biodegradable.
