Definitions

  • the invention has a lubricating oil and inhibitors against the Inclusion of metals in the same subject.
  • Lubricating oils usually have a viscosity of 10 to 1,500 mm 2 sec -1 at working temperature and are intended to reduce the sliding but also rolling friction between metallic and / or ceramic materials.
  • the oil film remaining in the combustion chamber should burn as residue-free as possible.
  • the oil film has a particularly small layer thickness in order to keep the oil consumption as low as possible and, on the other hand, that oxygen atoms are built into the oil molecules in order to ensure residue-free combustion, so that no additional undesirable particle emission is present in the exhaust gases from the engine.
  • contaminants, which are deposited in the machine elements, in particular the bearings be dispersed from the engine oil, so that the functionality of the machine elements is ensured.
  • the lubricating oils have a wide temperature range a constant viscosity have, so that on the one hand even at lower temperatures no greater resistance when moving the machine elements arises and on the other hand too thin at high temperatures Film of the lubricating oil is avoided, for which additives are used be so that the desired lubricating effect is ensured.
  • additives are known in lubricating oils, which the Corrosion of steel components but also aluminum, as is the case for avoid the pistons, or at least reduce them should.
  • mineral lubricating oils are also broken down by microorganisms subject to nature, there is a desire to mineral lubricating oils, through natural and / or artificial To replace carboxylic acid esters. These lubricating oils have different ones Advantages on. So it becomes largely residue-free Burn these compounds in an internal combustion engine it with spark or auto ignition, due to the oxygen atoms promoted in the molecule. Furthermore, the viscosity of the basic substance by choosing organic carboxylic acids as well the alcohols can be controlled particularly easily. By known Additives can also affect the viscosity behavior over a wide range Temperature ranges as well as the corrosion behavior influenced will.
  • esters Another advantage of the esters is that the ester bond of microorganisms much lighter than the carbon-carbon bond broken down by n- or iso-hydrocarbons can be. This easier microbiological degradability special attention is given to the fact that with a exponentially increasing number of vehicles, even at better motors, hydraulic motors and. absolutely the like There is a risk that larger amounts of such lubricating oils, be it due to accidents, leaky crankcase u. The like Environment.
  • Carboxylic acid ester oils were initially used for aircraft turbines used and already have the conventional ones mineral oils replaced because the oil change times on the Engine overhaul times could be extended.
  • Carboxylic acid ester oils are usually from dicarboxylic acids u. between Sebacic, adipic and azelaic acid. As alcohols are preferred those by oxosynthesis or aldol condensation obtained alcohols used.
  • Corresponding carboxylic acid ester oils are for example in EP 0 264 842 A2 or US 5,057,247 A.
  • the present invention has for its object a To create lubricating oil that has the lowest absorption capacity for tin, copper, iron, especially for lead and / or their Compounds at room temperature as well as elevated temperatures has that, including the additives, rapidly biodegradable and is not an additional biological burden for the environment represents. Furthermore, the additions which are the inclusion of metals or their compounds in engine oil prevent that Do not negatively influence the viscosity behavior of the lubricating oil, and with hydraulic oils, which are both as working medium and serve as lubricating oil, the water and air separation behavior don't worsen.
  • Antioxidants especially based on sterically hindered Phenols and amines, anti-foaming agents, detergents, dispersants, Demulsifiers, corrosion inhibitors, wear protection, consists essentially in that it is an additive, preferably 0.01 wt .-% to 0.5 wt .-%, an inhibitor against chemical extraction and / or extraction of tin, copper, Iron, and especially lead, from alloys, preferably Bearing alloys and cage alloys.
  • the mechanism of action is not known per se, but there is Possibility that the inhibitor together with the metals a kind of protective film, e.g. B. a complex or the like. Is formed, which against the extraction or chemical dissolution of the Metals in the metallic alloy works.
  • a kind of protective film e.g. B. a complex or the like.
  • the additive is present or has the same formula as a gallic acid ester where R is a methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, octyl and dodecyl radical, there is a particularly effective inhibitor which at the same time has low biological toxicity and is also particularly easy to decompose oxidatively and therefore does not cause any additional particles in the exhaust gas.
  • Gallic acid esters are known as oxidation inhibitors for pharmaceuticals, and it was quite surprising that these substances on the one hand prevent the uptake of lead or copper, tin and iron and their compounds in a carbonic ester oil and at the same time a quantitative oxidation of the oil film remaining in an internal combustion engine, to the extent it is oxidatively attacked, not delayed; Although water and air separation behavior are usually worsened by polar additives, no negative change in the property profile could be found, furthermore no additional deposits were necessary.
  • the additive for the lubricating oil can consist of phenothiazine or have such an additive, phenothiazine also is known as an oxidation inhibitor and again surprising was that such a substance extraction or chemical removal of the listed metals from machine components can prevent and furthermore no additional Particle emission and the water and air separation behavior not deteriorated, as well as no additional Deposits.
  • the addition can be according to another feature of the present Invention consist of phenoxazine or have the same.
  • a Phenoxazine is also known as an antioxidant and it was quite surprising that this connection was also the Extraction of tin, copper, iron and especially lead an alloy or the chemical extraction of these metals can prevent from an alloy, further the Particle emission in the exhaust gas of an internal combustion engine due to of these substances is not increased and no additional Deposits can be caused.
  • the invention further consists in the use of gallic acid esters of the following formula where R is a methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, octyl and dodecyl radical, in particular in an amount of 0.01% by weight to 0.5 %
  • R is a methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, octyl and dodecyl radical
  • the invention further consists in the use of Phenothiazine, in particular in an amount of 0.01 wt .-% to 0.5% by weight, as an inhibitor against lead absorption for a lubricating oil with 80 wt.% to 99 wt.% artificial and / or natural Carboxylic acid esters for machines, especially internal combustion engines, with spark and / or auto ignition, hydraulic Motors or the like.
