Definitions

  • the present invention relates to lubricant comprising an ester. More particularly, the invention relates to high temperature chain oils having improved volatility and functional life.
  • Lubricant compositions for use on drive chains, particle board presses, tenter frames and stenter frames require viscosity stability.
  • the present invention overcomes these and other disadvantages by including an alkyl-substituted naphthalene in a lubricant composition having an ester.
  • One object of the present invention is the provision of a lubricant for use with drive chains and other chain mechanisms operating in high temperature environments having improved viscosity characteristics.
  • Another object of the invention is to provide a high temperature chain oil having improved volatility characteristics and an increased functional life.
  • the lubricant composition of the present invention comprises an alkyl-substituted naphthalene and an ester.
  • an alkyl-substituted naphthalene it is contemplated that reference is made to naphthalene substituted with one or more straight or branched alkyl groups of varying lengths.
  • the present invention may comprise diesters, phthalates, trimellitates, pyromellitates, dimer acid ester, polyols and polyoleates. It is contemplated that trimellitic esters and polyols are particularly suitable.
  • an ester comprises from about 40 percent to about 90 percent by weight of the lubricant composition, alternatively from about 50 percent to about 80 percent.
  • Emkarate 9130 is a trimeilitic acid ester, available from ICI Chemical Polymers.
  • Mobil MCP 968 is a mixture of dialkyl- and trialkylnaphthalenes, available from Mobil Chemical Co.
  • Parapol 1300 and Indopol H-1900 are polybutene polymers.
  • Irgalube 349 is an antiwear additive available from
  • Emkarate 9130 and Mobil MCP 968 are combined and heated to a temperature of from about 70°C to about 85°C.
  • Parapol 1300 or Indopol H-1900
  • Irganox L06 and Vanlube SS are blended into the mixture.
  • Irganox L06 and Vanlube SS are powders which must be melted into the mixture, and the mixture must be blended until the Irganox L06 and Valube SS are thoroughly dispersed in the mixture.
  • the temperature of the composition is then lowered to about 60°C and Irgalube 349 and Nasul 707 are blended into the composition.
  • Samples of the lubricant compositions of the preceding Examples were prepared in accordance with the steps outlined in the preceding paragraph.
  • the isothermal evaporation of several samples was measured by subjecting a sample to the constant temperature in an instrument specifically designed for thermo-gravimetric analysis by TA Instruments.
  • t90 represents the time at which 10 percent by weight of the original sample had volatized (i.e., 90 percent by weight of the sample remained)
  • T50 indicates the time at which 50 percent by weight of the original sample had volatized (i.e., 50 percent by weight of the sample remained).
  • Formula B has the same ingredients in the same amounts as Example I except that in place of Mobil MCP 968 (a mixture of dialkyl- and trialkyl-naphthalenes), Formula B has additional Emkarate 9130 (a trimeilitic acid ester). Isothermal scans on 10 to 12 mg samples of Example I and Formula B were run at four different temperatures. The following results indicate the time at which 50 percent by weight of the original sample had volatized at each of the four temperatures (i.e. 50 percent by weight of the sample remained).
  • Mobil MCP 968 a mixture of dialkyl- and trialkyl-naphthalenes
  • Emkarate 9130 a trimeilitic acid ester
  • the lubricant composition of the present invention is notable for its ability to meet the demands of use of high temperature drive chain applications. However, the present invention is also suitable for use in other applications, such as gears and air compressors, as well as for any lubricant application where low volatility and increased functional life are desirable.
