Definitions

the invention relates to a new lubricant additive.
the known additives improve the basic lubricants with regard to the desired properties, such as. B. Reduction of abrasion, improvement of the lubricating film adhesion, increase of the oxidation resistance, lowering of the temperatures occurring during the friction, the continuous operating temperature etc., however, no longer meet the ever increasing requirements to a satisfactory extent.
the object of the present invention is therefore to provide a lubricant additive which further improves the properties of lubricants to such an extent that they meet the highest requirements fully satisfactorily. This object is achieved with the present invention.
the invention relates to a lubricant additive which can be obtained by reacting a salt of a tertiary amine which, as N-substituents, has two polyethylene oxide radicals with two or more ethylene oxide groups, the free OH group of which may be etherified or acylated, and a saturated or unsaturated long-chain alkyl group Ammonium molybdate and / or Mo03 (molybdic acid).
the tertiary amine salt is preferably used in a molar ratio of 1: 1 or greater; in particular, the weight ratio of tertiary amine salt to ammonium molybdate ((NH 4 ) 2 MoO 4 ) or MoO 3 is 50 to 70 to 20 to 40, and more preferably 60 to 25.
ammonium molybdate is also understood to mean ammonium heteropolymolybdates or ammonium isomolybdates.
it may be appropriate to choose the length of the polyethylene oxide residues according to the type of base oil or fat to which the lubricant additive according to the invention is to be added; Long chain polyethylene oxide residues, preferably with n 10 to 15, z. B. used especially for glycol-based base greases.
An alkyl radical with 1 to 7 carbon atoms can be branched or preferably straight-chain and is, for. B. methyl, ethyl, propyl, isopropyl, butyl, isobutyl, pentyl, hexyl, 2,3- or 4-methyl-pentyl; an acyl radical with 2 to 7 carbon atoms is e.g. B. one that is derived from the alkyl radicals mentioned above, such as. B. acetyl, propionyl etc.
the long chain saturated or unsaturated alkyl group can also be branched, but is preferably straight chain. It is preferably an alkyl radical derived from a saturated or unsaturated fatty acid, such as, for. B. the oleic acid derived oleyl radical (ectadecenyl).
the alkyl radical preferably has 12 to 24 and in particular 16 to 20 carbon atoms and is primarily oleyl.
any organic or inorganic acids such as, for. B. fatty acids, mineral acids and the like. Acids are preferred which themselves have an active activity in lubricant compositions, such as, for. B. phosphoric acids and partially esterified phosphoric acids, boric acid, sarcosides, mercaptobenzothiazoles, thioglycolic acid and other acids with acidic mercapto groups.
the reaction of the tertiary amine salt with the ammonium molybdate or MoO 3 takes place, in particular with a view to its later use as a package in the form of a solution or suspension in a mineral or synthetic oil, by heating in mineral or synthetic oil; the reaction is preferably carried out at a temperature of 100 to 220 ° C., in particular at 130 to 190 ° C. It is preferably reacted in the presence of a small amount of water. Good results give water additions of about 5 to about 20 wt .-%, based on the reaction product. This accelerates the reaction and lowers the required reaction temperature in the lower range.
the starting materials for the reaction are known or can be prepared in a manner known per se.
the preparation of the tertiary amine salt can e.g. B. by reacting a primary amine that already carries the long chain alkyl group as a substituent, for. B. of oleylamine, with ethylene oxide in the molar ratio required for the desired polyethylene oxide chain; the free OH group can subsequently in a known manner, for. B. etherified or esterified by reaction with an alkyl or acyl halide.
the conversion into the amine salt is expediently carried out by a simple salt formation reaction of the tertiary amine with the selected acid.
the lubricant additive preferably further contains one or more sulfur compounds from the group consisting of sulfurized esters, heavy metal dithiophosphates and heavy metal dithiocarbamates.
sulfur-containing esters of vegetable, animal or synthetic origin come into consideration as sulfurized esters; typical suitable commercial products are e.g. B. Lubrizol 5003® (sold by Lubrizol GmbH, Hamburg), Maisperm 2011® (sold by Lehmann, Voss & Co., Hamburg) and sulfurized jojoba oil.
Suitable heavy metal dithiophosphates are generally all dithiophosphates of the transition metals and rare earth metals, in particular the thiophosphates of antimony, lead, tin, iron, copper, manganese, molybdenum, nickel, vanadium, titanium and bismuth, and primarily zinc and tellurium.
the corresponding dithiocarbamates can also be used. In these compounds, all or some of the sulfur can also be replaced by selenium or tellurium.
the ratio of reaction product of tertiary amine and molybdenum compound to sulfur compound is preferably 1: 0.5 to 1:10.
the lubricant additive according to the invention is expediently present as a package in the form of a solution or suspension in a base oil (mineral or synthetic oil) and is sold and used in this form.
the lubricant additive content (tertiary amine salt / molybdenum compound reaction product and optionally sulfur compound and / or other conventional additives) is generally 30 to 90% by weight, and in particular 50 to 70% by weight.
Naphthenic or paraffin-based base oils and greases can be used as mineral base oils and greases, and all the usual classes for synthetic base oils and greases.
suitable synthetic oils are poly-alpha-olefins, glycols, esters, alkylbenzenes and silicone oils and fats soluble in organic solvents.
the lubricant additives according to the invention may contain further oil-soluble or non-oil-soluble additives which are customary for lubricating oils, such as, for. B. antioxidants, rust inhibitors, density swellers, antifoams, dispersants, dyes, viscosity index improvers, extreme pressure additives, but also other lubricant additives, such as. B. the additive combinations known from DE-AS 19 54 452.
oil-soluble or non-oil-soluble additives which are customary for lubricating oils, such as, for. B. antioxidants, rust inhibitors, density swellers, antifoams, dispersants, dyes, viscosity index improvers, extreme pressure additives, but also other lubricant additives, such as. B. the additive combinations known from DE-AS 19 54 452.
lubricating oils and greases with significantly improved properties can be obtained.
wear is reduced by the lubricant additive according to the invention, the adhesive strength of the boundary lubrication film is improved, the oxidation stability and thus the life of the lubricant is markedly increased and the coefficient of friction and thus also the operating temperature are reduced.
the coefficients of friction achieved with the lubricant additive according to the invention are extremely low.
the amount of lubricant additive according to the invention should generally be at least 3%, based on the finished lubricant composition, where the quantities most suitable for the respective lubricant and the respective intended use can easily be determined.
the lubricant additive according to the invention can also be used to produce lubricating oil or grease concentrates which are then added to the lubricant to the desired concentration.
the additives according to the invention can be used in an acidic, neutral or basic medium.
the invention therefore also relates to the use of the lubricant additive according to the invention for lubricants and greases, in particular for gear and engine oils.
the lubricant additive according to the invention it is, for. B. possible to use oils of low viscosity in applications where previously high viscosities were absolutely necessary, such as. B. in gears and differential gears.
solutions of the lubricant additive according to the invention obtained according to a), b) or c) can be used as such, optionally together with a sulfurized ester, a heavy metal dithiophosphate and / or a heavy metal dithiocarbamate as a package for producing improved lubricating greases and lubricating oils.
a lubricant additive package is produced which is used in the examples below as an additive for lubricants becomes.
a lubricating oil composition which contains 3% by weight of the package obtained according to Example 2 is produced by mixing the components.
a lubricant composition containing 8% by weight of the lubricant additive obtained according to Example 1 c) is obtained by mixing the Components manufactured.
the lubricant compositions a) or b) show properties which are similar to those obtained with the comparable lubricant compositions which contain 8% by weight of the package obtained according to Example 2, and which in addition to the reaction product of tertiary amine salt and molybdenum compound contain a sulfur compound.
FIGS. 1 to 20 The results of the tests are illustrated in FIGS. 1 to 20 in the form of SRV test sheets.
Figures 1 to 12 show the properties of lubricant compositions using the lubricant additive according to the invention
Figures 13 to 20 show the results without lubricant additive according to the invention or with other additives.
FIG. 1 illustrates a test in which the lubricant composition according to Example 3a) is subjected to a load increasing from 50 to 1000 Newtons under the specified operating conditions, without the lubricating effectiveness collapsing in the process. This means that the yield point of the metal is reached in the surface roughness without the lubricating effect of the grease composition according to the invention being lost.
FIGS. 2 to 7 In the tests illustrated by FIGS. 2 to 7 with a lubricant composition according to the invention according to Example 3 a) and the corresponding tests drawn for comparison (FIGS. 13 to 18) with Longtime PD 2, test specimens with a lapped surface (smooth) with a ground surface were used (rough) and also those with polished surface (mirror finish) used.
a comparison of FIGS. 4 to 6 with 15 to 17 shows the superiority of the grease according to the invention particularly clearly in the ground surface.
the results of the tests with lapped and with polished surface clearly show the superiority of the lubricant according to the invention.
With the polished surface it is particularly noteworthy that pitting occurred with the comparative product.
the differences in the lapped surface become increasingly serious as the load increases, in particular in the coefficients of friction and in the profilograms, but are already clearly evident at 200 N.
FIG. 8 shows the results with a lubricant composition according to Example 3 b) which, in comparison to Example 3 a), contains only half the amount of lubricant additive according to the invention; in comparison to FIG. 4 (lubricant composition according to Example 3a), a longer running-in time is required, but excellent friction coefficients are then also obtained.
FIG. 12 shows that excellent friction coefficients and surface smoothing according to the invention are achieved even with a grease.
