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.
  • the WO 2005/113640 A1 discloses formulations of low pulmonary toxicity functional fluids containing low unsaturation alkylene oxide copolymers. More particularly, this document relates to low inhalation toxicity water-glycol hydraulic fluids containing from 30 to 60% of a water-soluble polyglycol, from 0 to 40% antifreeze, such as ethylene glycol, from 20 to 45% water, from 0 to 15% thickener, from 0 to 5% corrosion additives, 0 to 5% defoamers and dyes, as well as 0 to 5% fatty acid amides included.
  • a water-soluble polyglycol from 0 to 40% antifreeze, such as ethylene glycol, from 20 to 45% water, from 0 to 15% thickener, from 0 to 5% corrosion additives, 0 to 5% defoamers and dyes, as well as 0 to 5% fatty acid amides included.
  • the WO 97/15643 A1 relates to a water-soluble lubricant composition consisting of a mixture of polyethylene glycol and an amine to which further additives are added, inter alia optionally biocides are added.
  • 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 microns.
  • 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.
  • 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 e.g. Sulfonates
  • nonionic surfactants e.g. Fatty alcohol ethoxylates or NPE
  • cationic surfactants e.g. quaternary ammonium compounds, water-soluble or water-emulsifiable carboxylic acid esters 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.
  • stain lubricants based on mineral oil or synthetic oil are usually harmful and / or ecotoxicological dyes required.
  • water-based lubricants a variety of toxicologically harmless water-soluble dyes to food colors can be used.
  • 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.
  • 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 contain.
  • Examples 1 and 3 to 5 are comparative examples.
  • Table 1 shows properties of Example Formulation 1 compared to a mineral oil based product. ⁇ b> Table 1 ⁇ / b> example 1 petroleum product Viscosity at 40 ° C ISO VG 32 ISO VG 32 pour Point -35 ° C -10 ° C Friction coefficient, SRV test 0.058 0,100 Hazen color number 35 140
  • 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 coverage), according to Reichert. ⁇ b> Table 2 ⁇ / b> Example 2 petroleum product Viscosity at 40 ° C 110 mm 2 / s 460 mm 2 / s pour Point -35 ° C -10 ° C Surface pressure according to Reichert wear scale according to VKIS worksheet 3500 N / cm 2 2800 N / cm 2 Hazen color number 130 230
  • An oil foam consists of Water dist. 50.0% by weight propylene glycol 15.0% by weight Polyethylene glycol high molecular weight 25.0% by weight Foaming fatty alcohol ethoxylate 5.0% by weight Alkanolamine and boric acid derivative 2.0% by weight Sulfurized fatty acid 3.0% by weight
  • 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.
  • a further advantage of the application as foam is the improved wetting of the entire surface of the tribosystem, which allows a shortened run-in time and an improved run-in behavior.
  • illustration 1 shows a significantly lower torque of foamed (not water-based) lubricant bearing within the first 120 minutes running time.
  • a bb. 1 Current consumption of a lubricated with lubricant A bearing. Gray curve: standard application. Black curve: application as a foam.
  • Table 3 shows properties of Example Formulation 4. ⁇ b> ⁇ u> Table 3 ⁇ / u> ⁇ /b> Walkpenetration DIN ISO 2137 NLGI 2 Base oil viscosity, DIN 51562 90 cst Flow pressure at -30 ° C, DIN 51805 ⁇ 1400 mbar
  • Lubricant consisting of: Water dist. 27.5% by weight Polyalkylene glycol high molecular weight 50.0% by weight alkylene 10.0% by weight Carboxylic acid derivative M-528, Cortec 2.0% by weight Water-soluble carboxylic acid ester 10.0% by weight acrylic copolymer 0.5% by weight
  • This lubricant is suitable for the lubrication of 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.
