Definitions
- the invention relates to a new lubricant or lubricant concentrate based on mineral oil and / or synthetic oil with improved lubricating properties, in particular improved load bearing, sliding and corrosion protection properties.
- solid lubricants were developed which were introduced between the moving metal parts, such as graphite, MoS2, TiO2, Ca3 (PO4) 2, Teflon and the like, which were introduced as lubricious outer layers, suspensions, pastes or greases. Thereby the friction partners were better separated and their resilience increased. With centripetal movements of higher peripheral speed and at higher temperature, however, the solid lubricants and carrier media separate sooner or later due to their different specific densities. This limited the long-term lubrication. In a further step, it was possible to apply suitable metal cations to rubbing surfaces during operation from chemical complexes dissolved in a lubricant.
- DE-PS 941 678 discloses lubricating oils containing soluble reaction products of phosphorus pentasulfide with liquid or solid aliphatic hydrocarbons or terpene hydrocarbons.
- a lubricating oil is known which contains metal-containing alkylphenol sulfide esters in combination with zinc sulfonates.
- DE-AS 1 444 892 a lubricating oil is known which contains a salt of an aromatic zinc dithiophosphate and a zinc carboxylic acid salt in the presence of water. While the first two products are lubricating oil detergents, the latter product is intended to prevent corrosion of silver bearing surfaces.
- a lubricating oil which contains a salt of a substituted succinic acid, optionally together with a salt of an alkylated or esterified phosphoric acid. It is an antioxidant with a detergent effect.
- a combination of dithiophosphate and dithiophosphinate salts is known from DE-AS 1 271 878.
- From DE-OS 15 94 555 cutting oils containing free sulfur, a dialkyldithiophosphate and a chlorinated hydrocarbon are known.
- Lubricating oils containing zinc or antimondithiocarbamate are known from US Pat. No. 3,462,367. Lubricating oils are known from US Pat. No.
- Lubricating oil additives are also known from US Pat. No. 2,734,864, which are formed from a dithiophosphate of the alkaline earth metal salts in combination with a complex reaction product of phosphorus sulfides, wool fat and alcohol esters.
- the undefined product contains considerable amounts of barium and zinc.
- Such a lubricating oil additive cannot be used in practice because of its unbearable odor, which also endangers the people who come into contact with it.
- lubricants based on mineral oil or synthetic oil which, in addition to the mineral or synthetic oil, contain an ester of an epoxidized fatty acid having 10 to 18 carbon atoms with mono- or polyhydric alcohols, an alkyl -, Aralkyl- or aryldithiophosphate of zinc, lead, tin, tungsten, molybdenum, niobium or lanthanum and optionally contain a sulfur phosphorus compound.
- lubricants based on mineral or synthetic oil or lubricant concentrates which in addition to a lead, tungsten, molybdenum and / or vanadium dithiophosphate esterified with alkyl, aryl or aralkyl groups, also contain at least one zinc dialkyldithiophosphate and a metal-free sulfur-phosphorus compound.
- These last-mentioned lubricants which have found widespread use, no longer meet all of the requirements placed on modern long-term and high-performance lubricants. Their coefficient of friction and abrasion are too high, their shelf life is inadequate in long-term use, and the complaint rate in the lubrication area is too high.
- the object of the invention was therefore to create a new lubricant or lubricant concentrate based on mineral or synthetic oil, which is further improved with regard to its lubricating properties, in particular its friction and wear properties, thus noticeably reducing the energy and spare parts requirement and thus also meets the highest requirements.
- the lubricants or lubricant concentrates according to the invention have significantly improved properties compared to the known lubricants or lubricant concentrates, in particular with regard to friction and wear, and thus have a reduced need for energy and spare parts. It is believed that this is due to the fact that when they are used in the rubbing and sliding area, metallic glass surfaces are formed from amorphously solidified metal melts, which no longer have metal crystal lattice structures.
- the glass-like smooth friction and sliding surfaces which are presumably produced with the lubricant or lubricant concentrate according to the invention, significantly improve the entire lubrication process, since the coefficient of friction and with it the abrasion, oxidation and corrosion are significantly reduced.
- the so-called fretting rust is also prevented by the lubricant or lubricant concentrate according to the invention.
- the lubricants or lubricant concentrates according to the invention are extremely environmentally friendly since they contain no lead, no sulfurized whale sperm oil and hardly any phosphorus. This has been shown by fish tests and bacteria washing tests which were carried out with the lubricants or lubricant concentrates according to the invention. It was also found that they are 60% biodegradable in normal soil within 3 to 4 months, so that they can also be described as extremely environmentally friendly.
- the quaternary carbon atom-containing polyol ester compounds used according to the invention are thermally very stable and therefore allow high operating temperatures of up to 300 ° C. They therefore open up the possibility of lifetime lubrication of highly loaded motors, turbines, rolling bearings, constant velocity joints and other high-performance machine elements.
- lubricant or lubricant concentrate based on mineral and / or synthetic oil used here means both lubricating oils and lubricating greases based on mineral and / or synthetic oil.
- Compounds containing quaternary carbon atoms are to be understood here as those compounds in which the four main valences of at least one carbon atom per molecule are occupied by four carbon atoms.
- Such compounds are mono-, di- and trimeric pentaerythritol esters, other polyol esters, pentaerythritol ethoxy esters and telomeric acid pentaerythritol esters and the corresponding ethoxylated esters.
- the lubricants or lubricant concentrates according to the invention have significantly improved properties compared to the known lubricants or lubricant concentrates, as the examples below show.
- the glass-like smooth friction and sliding surfaces produced by the lubricant according to the invention save drive energy and lower the coefficient of friction per se and by building up a very adhesive boundary lubrication film which enables elastohydrodynamic lubrication even under point loads.
- the friction temperature of the lubricant and lubrication point is reduced, the oxidation resistance of both is extended and the metallic friction partners are subjected to less specific alternating loads and temperatures. Overall, these effects greatly reduce wear and significantly increase the service life of the friction partners and the lubricant.
- the lubricant or lubricant concentrate contains, as component (b), mono-, di- or tripentaerythritol, the alcoholic hydroxyl group (s) of which is preferably an unbranched or branched alkyl, aralkyl or aryl group having 6 to 18 carbon atoms 6 to 12 carbon atoms, in particular 8 to 12 carbon atoms, is (are) esterified or ethoxy-esterified.
- component (b) mono-, di- or tripentaerythritol
- the lubricant or lubricant concentrate additionally contains a component with at least one free hydroxyl group.

- the lubricant or lubricant concentrate according to the invention contains as component (b) an ester and / or ethoxylated ester derivative of mono-, di- or tripentaerythritol and / or a telomeric acid pentaerythritol ester or an ethoxylated derivative thereof.
- the lubricant or lubricant concentrate according to the invention preferably contains beet oil, natural oil and / or a synthetic oil with a viscosity in the range from 1.0 mPa.s at 20 ° C. to 2.10 ° mPa.s at 20 ° C.
- a mineral oil with a viscosity is particularly preferred from 1.0 mPa.s at 20 ° C to 540 mPa.s at 50 ° C as a natural oil and the use of an aromatic or aliphatic dicarboxylic acid ester, in particular poly- ⁇ -olefin-dicarboxylic acid ester, especially butyl ester, with a molecular weight in the range of 1000 to 3000, preferably of phthalic acid diisodecyl ester, trimethyladipic acid diidyl ester and sebacic acid diocyl ester, a polyisobutylene with a molecular weight of 1000 to 100,000 and a viscosity of 200 to 43,000 mPa.s at 100 ° C, a polymethacrylate with a viscosity of 1000 mPa.s at 100 ° C, a non-water-soluble polyglycol with a viscosity of 5 to 60 mPa.s
- lubricant according to the invention and lubricant concentrate preferably contains a sulfur carrier, particularly a thiazole, at least one metal dialkyldithiocarbamate and / or a metal dialkyldithiophosphate and / or a phosphorus carrier, in particular an organo phosphite, preferably a Dialkylarylphosphit, particularly didecyl or Didodecylphenylphosphit, and / or a metal dialkyldithiophosphate .

- the sulfur carrier is preferably present in the lubricant or lubricant concentrate in an amount of 0.5 to 10% by weight, in particular 1 to 3% by weight, while the phosphorus carrier is preferably present in an amount of 0.1 to 10 % By weight, in particular from 0.1 to 5% by weight, especially from 0.5 to 2% by weight.
- the lubricant or lubricant concentrate according to the invention can contain conventional antioxidants, metal deactivators, detergents, dispersants, antifoams and / or viscosity index improvers as further conventional additives.
- polyolester compounds used according to the invention with at least one quaternary carbon atom in the molecule include the following compounds:
