Definitions
- the present invention relates to water-based lubricants.
- the invention relates to the use of water-based lubricants for the lubrication of friction partners in drive elements, as well as their use.
- Lubricants are used in particular in drive elements, such as chains, gears, rolling and plain bearings or seals on rotating shafts. These lubricants are based on mineral oil or synthetic hydrocarbons. Especially in rolling and plain bearings, the lubricants ensure that a separating, load-transmitting lubricating film is built up between the sliding or rolling parts. This ensures that the metallic surfaces do not touch and thus no wear occurs. The lubricants must therefore meet high requirements with regard to: cooling the friction point, extreme operating conditions, such as very high and very low speeds,
- the operating fluid consists of a mixture of water and an aliphatic hydrocarbon in which graphite particles are suspended as a solid lubricant.
- This solid lubricant is in the form of flaky graphite particles having a particle size of less than 50 pm.
- Further components of this lubricant and coolant are dispersing additives, defoamers, corrosion inhibitors. Disadvantages of this operating fluid are the graphite particles present in solid or flaky form, which on the one hand can settle out of the suspension and thus adhere the operating parts to be lubricated.
- Another disadvantage is the persistent contamination of components that come into contact with graphite-containing lubricants. If a filtration of the lubricating oil is required during operation, the graphite may lead to a clogging of the filter pores. In addition, the operating fluid has a very low viscosity, which can lead to failure of the lubricating film at high loads.
- the present invention was therefore based on the object to provide a water-based lubricant that meets the above requirements, in particular is biodegradable and that helps to significantly reduce the production of carbon dioxide.
- a lubricant consisting of water, water-soluble polyalkylene glycols, water-soluble emulsifiers and lubricant-compatible additives is used.
- the water-soluble polyalkylene glycols are selected from the group of randomly distributing polyoxyethylene and polyoxypropylene units and / or other polyoxyalkylene units having one or more hydroxyl end groups, from a block polymer of polyoxyethylene and / or polyoxypropylene units and / or other polyoxyalkylene units.
- anionic surfactants for example sulfonates, nonionic surfactants, eg fatty alcohol ethoxylates or NPE or cationic surfactants, for example quaternary ammonium compounds, water-soluble or water-emulsifiable carboxylic acid esters are used.
- the low-temperature behavior of water-based lubricants by the addition of antifreeze e.g. low molecular weight glycols, glycerol, salts or ionic liquids can be significantly improved.
- additives can be added to influence the properties of the lubricant targeted. These may be in soluble or dispersed, colloidal or nanoscale form.
- water-based lubricants can also be formulated foaming.
- the application as a spray foam is of particular interest here, because it allows a visual control of the lubricant application. In the case of contamination of textiles or machine parts with water-based lubricating fluids, these are easy to clean.
- the "base oil” according to the invention can also be converted into a lubricating grease or a lubricating paste by mixing with soap or urea powders, layered silicates or other common lubricant thickeners.
- Lubricant contains:
- water-soluble polyalkylene glycol selected from the group consisting of randomly distributed polyoxyethylene and / or polyoxypropylene units and / or other polyoxyalkylene units, a block polymer of polyoxyethylene and / or polyoxypropylene units and / or other polyoxyalkylene units,
- foaming or non-foaming emulsifiers from the class of anionic (eg sulfonates), nonionic (eg fatty alcohol ethoxylates or also NPE) or cationic (eg quaternary ammonium compounds) surfactants or water-soluble or water-emulsifiable carboxylic acid esters, 0.5 to 50 wt. % Antifreeze selected from the group consisting of alkylene glycol, glycerol, salts or ionic liquids,
- corrosion additives such as alkanolamines, boric acid or carboxylic acid derivatives
- the lubricant composition may contain the following components:
- biocides e.g. Sorbic acid and / or
- the lubricant composition 0.5 to 40 wt .-% lubricant thickener selected from the group consisting of metal soaps of mono- and / or dicarboxylic acids, ureas, phyllosilicates, solid lubricants and Aerosil
- Such a compounded lubricant is particularly suited by the solid lubricant-free concept for applications in which the lubricant is continuously filtered, e.g. Transmission in wind turbines.
- Table 1 shows properties of Example Formulation 1 compared to a mineral oil based product.
- Alcohol polyglycol ether 5.0% by weight
- Example 1 shows advantages of the lubricant already described in Example 1 .
- the addition of nanoparticles ensures even greater wear protection.
- Table 2 shows properties of Example Formulation 2 compared to a mineral oil based product. Despite its clearly low viscosity, the aqueous formulation has significantly improved wear protection (higher achievable surface pressure) according to Reichert.
- An oil foam consists of
- the pour point of the formulation is -20 ° C.
- This composition has a high foam formation, which allows the application by means of spray / pump spray as a foam.
- Such an application has the advantage that the lubricant on the surface can be detected well visually, even with minimum quantity lubrication immediately after application, for example with the focus quality assurance.
- Another advantage of the application as a foam is the improved wetting of the entire surface of the tribosystem, which enables a shortened run-in time and an improved run-in behavior.
- Figure 1 shows a significantly lower torque of a foamed (not water-based) lubricant bearing within the first 120 minutes running time.
- Fig. 1 Current consumption of a lubricated with lubricant A bearing.
- Table 2 shows properties of Example Formulation 4.
- Lubricant consisting of:
- This lubricant is suitable for lubricating seals on rotating shafts and in contrast to the known lubricants of mineral oils or synthetic hydrocarbons well biodegradable and therefore environmentally friendly to dispose of. It is characterized by a low friction, good cooling effect, good compatibility with rubber-elastic materials and has a low Geissesserverschmutzungspotential. Advantageously, it changes the viscosity when diluted with water only slightly and therefore allows the formation of an effective lubricating film.
- the water-based lubricant according to the invention can be used for lubricating drive elements in chains, gears, rolling and sliding bearings or for lubricating seals on rotating shafts in the form of a foam, spray or emulsion by means of spray or pump spray devices with the focus of better surface wetting and the better Detectability of thin lubricating films is applied, can be used.
