Description

"Fluorine-containing lubricants"

The present invention relates to the use of formulations which contain at least one fluorinated component for reducing the friction between transport goods and transport systems.

In the food industry, in particular in beverage companies, the containers to be filled in the filling plants are transported by means of conveyors of various designs and materials, for example by means of plate conveyor belts or chain-like arrangements, which are generally referred to below as transport chains. The transporters establish the connection between the various optional treatment stages of the filling process such as B. Unpacker, bottle washer, filler, capper, labeler, packer, etc. The containers can be of various shapes, in particular glass and plastic bottles, cans, glasses, barrels, beverage containers (KEG), paper and cardboard containers. To ensure trouble-free operation, the transport chains must be lubricated in a suitable manner so that excessive friction against the containers is avoided. Diluted aqueous solutions containing suitable friction-reducing agents are usually used for lubrication. The transport chains are brought into contact with the aqueous solutions, for example by immersion or spraying, in which case one speaks of splash lubrication systems or automatic belt lubrication systems or central chain lubrication systems.

The chain lubricants hitherto used as lubricants are mostly based on fatty acids in the form of their water-soluble alkali metal or alkanolamine salts or on fatty amines, preferably in the form of their organic or inorganic salts. While both substance classes can be used without problems in splash lubrication, they show a number of disadvantages in the central chain lubrication systems that are common today. Thus, DE-A 23 13 330 soap-based lubricants, the aqueous mixtures of C- _j gC-is-fatty acid salts and surfactants

Contain substances. Such soap-based lubricants have the following disadvantages:

1. There is a reaction with the water hardness, ie the alkaline earth ions, and other water constituents with the formation of poorly soluble metal soaps, the so-called primary alkaline earth soaps.

2. There is a reaction between these soap-based lubricants and carbon dioxide dissolved in water or the product to be filled.

3. The application solution created in this way is always germ-promoting.

4. When hard water is used, ion exchangers are required for water softening, which means an additional source of germs (and therefore can hardly be found in practice), or the use of highly complexing agent-containing products, which in turn is ecologically questionable, is necessary.

5. There is increased foam formation, which can cause problems in particular with the bottle inspector (automatic bottle control) and result in greater wetting of the transport containers.

6. Most of these products contain solvents.

7. The cleaning effect of these products is poor, so that a separate cleaning is necessary.

8. Such soap-based lubricant preparations show pH-dependent performance.

9. Soap-based lubricant preparations continue to be dependent on water temperature.

10. Soap-based lubricants only have a low storage stability, especially at low temperatures.

11. The EDTA (ethylenediaminetetraacetate) contained in many products is known to be poorly biodegradable. 12. Such soap-based lubricant preparations are not suitable for all transport goods made of plastic, since in many cases stress corrosion cracking on the transport goods occurs when these agents are used.

In addition to soap-based lubricants, mainly those based on fatty amines are used. For example, DE-A-36 31 953 describes a method for lubricating chain-shaped bottle conveyor belts in beverage bottling plants, particularly in breweries, and for cleaning the belts by means of a liquid cleaning agent, which is characterized in that the chain-shaped bottle conveyor belts are based on belt lubricants neutralized primary fatty amines, which preferably have 12 to 18 carbon atoms and contain an unsaturated fraction of more than 10%.

Lubricants based on polytetrafluoroethylene are used in some filling plants. These are in the form of dispersions and are not applied to the chains via nozzles, as is usually the practice, but with brushes. These agents have the advantage that they bring about a substantial reduction in the friction between the conveyor belts and the goods to be transported. In addition, the polytetrafluoroethylene adheres very strongly to the chains.

In practice, it turned out to be disadvantageous that the overall hygienic condition with regard to contamination and contamination of the transport chains deteriorated. This even went so far that the performance profile of the lubricant deteriorated over time due to the increase in contamination.

Another disadvantage was that the dispersions of polytetrafluoroethylene were not stable in storage and separated over time. The consequence of this is that observed over a long period of time does not result in constant amounts of active ingredient on the transport chains.

When trying to clean the transport chains, it was found that the lubricant layer was very difficult to remove from the transport chains. When checking the compatibility of polytetrafluoroethylene dispersions with regard to their plastic compatibility, it was also found that they produce stress cracks on PET bottles.

The object of the present invention is to provide lubricants based on organic fluorine compounds which, on the one hand, are stable in storage, on the other hand are well compatible with plastic containers and at the same time improve the lubricating performance compared to the amines usually used as lubricants.

The present invention relates to the use of formulations which contain at least one fluorinated component selected from the groups of a) per- or partially fluorinated monomeric organic compounds, b) pure and mixed di- and oligomers which are based on at least one per- or partially fluorinated organic monomer , c) pure and mixed polymers which are based on at least one per- or partially fluorinated organic monomer and in the polymer there is at least one monomer unit which is either less than 75% by weight of fluorine, based on the weight of the total monomer unit, or more than 2 ° C. -Atoms contains, included, to reduce the friction between cargo and transportation equipment.

When defining the boundary between oligomers and polymers, the present invention relates to the generally known characterization of polymers which are composed of so many identical or similar low molecular weight building blocks (monomers) that the physical properties of these substances, in particular the viscoelasticity, contribute to No longer noticeably change the increase or decrease in the number of blocks by one unit. This is generally the case when the average molecular weight of the "polymers" is 10,000 g / mol or more. The term oligomers is used for the low molecular weight dimers, trimers and other lower members of the polymer homologous series. In a preferred form, group a) comprises at least per- and partially fluorinated surfactants, alkanes, ethers and amines, particularly preferably in the formulations used according to the invention ammonium perfluoroalkylsulfonates, lithium perfluoroalkylsulfonates, potassium perfluoroalkylsulfonates, amine perfluoroalkylsulfonates, sodium perfluoroalkylsulfonates, potassium fluoramate carboxylates, potassium fluoramate carboxylates, ammonium iodides, ammonium perfluoroalkyl carboxalates, fluorinated alkyl polyoxyethyl enethanols, fluorinated alkyl alkoxylates, fluorinated alkyl esters with concentrations of 0.001 to 10% are used.

While stable formulations composed of polytetrafluoroethylene dispersions and antimicrobial components are not or only very difficult to obtain, the formulations to be used according to the invention with antimicrobial components usually result in stable formulations.

It is further preferred that the formulations to be used according to the invention additionally have at least one component selected from the group of the polyhydroxy compounds, in particular from the groups of the polyalcohols and carbohydrates, and very particularly preferably one component selected from polyhydric alcohols, preferably alkane diols, alkane triols, particularly preferably glycerol and the polyethers derived therefrom, as well as glucose, arabinose, ribulose, fructose and the oligosaccharides and / or polysaccharides derived therefrom and their esters and ethers.

In a likewise preferred embodiment, the formulations to be used according to the invention contain further components selected from the groups of the surfactants and solubilizers, it being particularly preferred that at least one alkyl polyglycoside is contained as the surfactant. Further preferred constituents are fatty alkyl amines and / or their alkoxylates, in particular coconut fatty amine ethoxylates and / or imidazoline compounds and / or amphoteric surfactants and / or nonionic surfactants and / or ether carboxylic acids and / or ether amine compounds. In addition, it is preferred to add paraffin compounds to the formulations to be used according to the invention. The water content in the according to the invention Formulations using is preferably less than 20 wt .-%, very particularly preferably less than 10 wt .-%, based on the entire formulation, with the formulations not containing water in very specific embodiments, which means in the sense of the invention that the formulation does not water is added intentionally. In practice, the formulations to be used according to the invention are applied to the transport chains, and in the best case it can be observed that no foam is produced when the transport goods are transported on the transport systems. It is further preferred that the formulations to be used according to the invention are compared to conventional lubricants which are diluted with water in transport systems by a dilution factor of more than 100 and in the event that equal amounts of lubricating components are applied to the conveyor belt system within a defined period of time are, when using formulations to be used according to the invention, the frictional resistance between transport goods and conveyor belt system is reduced by more than 20%. This can be shown by example experiments.

Example 1 :

A comparative formulation 1, which contains 5% by weight of coconut propylene diamine and is adjusted to pH 7 with acetic acid, is applied in a 0.2% aqueous concentration to the. Via a nozzle assembly with 5 nozzles, each of which has a spray rate of 5 liters per hour Transport chains applied. Over a period of 1 hour, 50 ml of the comparison formulation, or approximately 2.5 g of the coconut propylene diamine, thus reach the transport chains. This test is carried out over a period of 10 hours. According to the present invention, the coefficient of friction between the beverage bottle and stainless steel transport chains is defined as the ratio of the pulling weight which is exerted, for example, on a spring balance when one tries to hold a beverage bottle while the transport chains are running, to the weight of the bottle.

The coefficient of friction when using the comparative example μ = 0.10 described above. As soon as you stop the dosing process, the coefficient of friction increases quickly arrives and the goods or bottles fall over within a few minutes.

In the comparative example, a total of 25 ml of lubricating-active coconut propylene diamine raw materials reach the transport chains over the entire test period of 10 hours. In a second experiment, 25 ml of a formulation to be used according to the invention, consisting of 5% by weight of perfluoropolyether and 95% by weight of glycerol, are distributed on the transport chains with a rag. The coefficient of friction between bottles and transport chain is then measured over a period of 10 hours under identical conditions, as in the experiment with comparative example 1. The coefficient of friction μ lies between 0.04 and 0.05 over the entire period of 10 hours. This example shows that the frictional resistance between goods to be transported and the conveyor belt system can be reduced by more than 20%, in the present example even by more than 40%.

A further preferred embodiment of the present invention is the use of the formulations to be used according to the invention for the transport of plastic containers, the plastic containers particularly preferably at least one polymer selected from the groups of polyethylene terephthalate (PET), polyethylene naphthenate (PEN), polycarbonate (PC), PVC contain and are particularly preferred PET beverage bottles. In a laboratory test, stress corrosion cracking is measured using a comparative example based on 5% polytetrafluoroethylene dispersion compared to a 5% perfluoropolyether solution in 95% glycerol.

Example 2:

According to the test description, PET bottles are filled with water and conditioned with carbon dioxide so that there is a pressure of about 7 bar in the interior of the bottles. The bottom cups of the bottles are then immersed in the formulation of the comparative example or the example to be used according to the invention and placed in a Petri dish over a period of 24 hours. After the 24 hours, the bottles are opened, emptied and the floor cups rinsed with water. A visual evaluation of the floor cups shows that there are many stress cracks with medium depth, rating C, in the test with the comparative example, while it is found in the test with the example to be used according to the invention that only a few stress cracks with low depth, rating A , are available. The classification is based on the reference images contained in Chapter IV-22 of the book 'CODE OF PRACTICE - Guidelines for an Industrial Code of Practice for Refillable PET Bottles', Edition 1, 1993-1994.

Example 2 shows that the formulations to be used according to the invention have advantages over the transport of plastic bottles compared to polytetrafluoroethylene dispersions.
