  • 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 Mo0 4 ) or Mo03 is 50 to 70 to 20 to 40, and more preferably 60 to 25.
  • Ammonium molybdate in the context of the invention also means ammonium heteropolymolybdates or ammonium isomolybdates.
  • 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. 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 Mo03 takes place, in particular with regard to their 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; preferably the Implemented 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.

  • Suitable heavy metal dithiophosphates are generally all dithiophosphates of transition metals and rare earth metals, in particular the thiophosphates of antimony, lead, iron, tin, copper, manganese, molybdenum, nickel, vanadium, titanium and bismuth, and primarily zinc and tellurium.
  • the corresponding dithiocarbamates can also be used. In this compound, 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 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, 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 other 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.
  • the wear by the inventive lubricant additive lowered the adhesive strength of the boundary lubrication f ilmes improved oxidation stability and thus the life of the lubricant is pronounced increases and the coefficient of friction and thus also the operating temperature is lowered.
  • 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, the amounts most suitable for the respective lubricant and the respective intended use being easy have it 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. By using 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.

  • 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.
  • Example 1 illustrates a test in which the lubricant composition according to Example 3a) is subjected to a load which increases 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 a polished surface (mirror finish) are used. At the same load (at 300 N), 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. But 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.
  • Example 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.
