Definitions

  • the invention relates to a grease composition
  • a grease composition comprising a base oil and a smaller proportion of a thickener based on a polyurea compound, and also conventional additives.
  • Such lubricants are e.g. known from DE-OS 33 03 442, wherein the base oil is a mineral or synthetic oil, such as a naphthenic or paraffin-based base oil and the thickener is the reaction product of an isocyanate with at least 3 isocyanate groups in the molecule with a long-chain aliphatic monoamine, preferably with 16 to 24 C. -Atoms is.
  • Such grease compositions can be used for continuous operating temperatures of 150-160 ° C.
  • compositions which, however, contain an ester as the base oil and have a consistency with a penetration of 220 to 385 at 0.1 mm and wherein the thickener consists of an aromatic mono- or diisocyanate and an alkyl, alkenyl radical with 8 to 22 carbon atoms or Aryl radical composed of 6 to 10 carbon atoms has been found to be particularly noise-absorbing, the property being particularly important in the case of mechanically moving parts in electronic devices, such as turntables, tapes and video devices, etc.
  • Grease preparations of this type are suitable for rolling bearings that have to withstand temperatures up to 180 ° C.
  • Such greases correspond to NLGI class 3 to 0 according to DIN ISO 2137.
  • the preferred base oils have a viscosity of 18 to 400 mm2 / s at 40 ° C.
  • Lubricants are preferably used in which the base oil is a C8 to C13 alcohol ester of phthalic acid, trimellitic acid or pyromellitic acid and the thickener is the reaction product of a methylene-bis-phenyl isocyanate or tolylene diisocyanate such as a mixture of 2,4- and 2,6-tolylene diisocyanate, represents with a C6 to C22 alkylamine or amines or naphthylamine.
  • the base oil is a C8 to C13 alcohol ester of phthalic acid, trimellitic acid or pyromellitic acid
  • the thickener is the reaction product of a methylene-bis-phenyl isocyanate or tolylene diisocyanate such as a mixture of 2,4- and 2,6-tolylene diisocyanate, represents with a C6 to C22 alkylamine or amines or naphthylamine.
  • the additives used against corrosion, oxidation and for protection against metal influences which act as chelate compounds, radical scavengers, UV converters and the like, are known per se and are commercially available.
  • the noise test is carried out by means of a test arrangement which is particularly suitable for this purpose, a suitable roller bearing being run at speeds of 1800 rpm.
  • the noise is measured directly on the outer ring of the rolling bearing using an accelerometer.
  • the vibrations recorded by the device are divided into three frequency ranges (low 50 - 300 Hz, medium 300 - 1800 Hz, high 1800 - 10000 Hz). In addition, maximum peaks are also registered.
  • the measured values are evaluated by a computer and referenced to the values measured with a reference lubricant.
  • the lubricant preparation according to the invention shows values in all areas of around 100% compared to a lubricant made from mineral oil and polyurea, which shows peak values of up to 368%.
  • the fat is homogenized by repeated rolling on a three-roll mill. This homogenization process is of particular importance for the noise behavior. In this way, a grease of NLGI class 0 according to DIN ISO 2137 is obtained.
  • This fat obtained in this way is tested on a noise test bench, which differentiates according to three frequency bands and maximum peaks.
  • a significant noise reduction was measured compared to a commercially available lubricating grease made from a mineral oil and a long-chain, branched polyurea compound.
  • Example 2 In 839.5 g of an ester oil consisting of an ester of pyromellitic acid and an isomeric C-8 alcohol, diisocyanate and amine are reacted as in Example 2. Implementation, additives and homogenization are carried out in the same way as in Example 1.
