Definitions

  • Synthetic lubricants find increasing utility because of their uniformity and stability.
  • synthetic lubricants containing polyol esters exhibit many desirable properties.
  • a lubricant for modern vehicle transmissions must meet a number of exacting criteria. Modern transmissions may be enclosed in sound absorbing materials which have the side effect of acting as a heat insulator and raising the lubricant temperature.
  • seal swell characteristics of a lubricant composition are of great importance if leakage of engine fluids is to be held to an acceptable level.
  • Polyol esters used as lubricants often exhibit a tendency for unacceptably high seal swell.
  • Polyalphaolefins used as lubricants often exhibit negative seal swell and are not as thermally stable as polyol esters.
  • U.S. Patent 4,144,183 describes improvement of the viscosity temperature behavior of ester oils by using mixtures of branched and straight chain carboxylic acids in a polyol esterification.
  • U.S. Patent 4,234,497 describes improvement of seal compatibility characteristics of polyol ester lubricants by esterifying a polyol with a mixture of iso-palmitic acid and a C 5 -C 11 carboxylic acid.
  • Synthetic lubricants are frequently given desirable viscosity characteristics by inclusion of a viscosity index improver.
  • the viscosity index improver is most often a polymer which degrades with the passage of time. This gradual degradation limits the useful life of a formulated lubricant. It is desirable to prepare synthetic transmission lubricant compositions having good stability, acceptable range of viscosity, and good seal swell characteristics without the inclusion of degradable viscosity index improver or a seal swell agent.
  • This invention relates to lubricating compositions and methods for their use in lubricating machinery.
  • a synthetic transmission lubricant composition is formulated from: (A) a polyol ester prepared by the esterification of trimethylolpropane with 8 to 12.. carbon atom monocarboxylic acid, (B) a polyol ester prepared by the esterification of trimethylolpropane with a branched chain 18 to 24 carbon atom monocarboxylic acid, and (C) a liquid polyalphaolefin.
  • the synthetic lubricant of this invention is intended for general and heavy duty use in the transmissions of internal combustion engines. It finds particular application in heavy duty transmissions in over- the-road commercial vehicles such as buses and trucks.
  • the defining characteristics of an acceptable transmission lubricant for the purposes of this invention are those of the Detroit Diesel Allison 10W Type C-3 Hydraulic Transmission Fluid Standard.
  • the synthetic lubricants of this invention qualify for the Detroit Diesel Allison 10W Type C-3 lubricant rating and meet the test specifications set out in Table I below:
  • the synthetic transmission lubricant of this invention has as its essential ingredients:
  • the weight ratio of ingredient (A) to ingredient (B) is preferably from 1.6:1 to 1.2:1, and the weight ratio of the sum of ingredients (A) plus (B) to ingredient (C) is preferably from 2.1:1 to 1.6:1
  • the sum of ingredient (A) plus ingredient (B) plus ingredient (C) preferably comprises from about 90 to about 93 weight percent of the composition.
  • the synthetic transmission lubricant consists essentially of its essential ingredients (viz., A, B, C) and conventional optional lubricant ingredients.
  • the optional ingredients of the lubricant composition are preferably less than 8 weight percent of the total composition.
  • a suitable ratio of (A):(B) and a suitable ratio of (A+ B ):(C) may be approximated by a linear additive model wherein each ingredient contributes to total viscosity in direct proportion to its individual viscosity multiplied by its weight proportion in the composition (within the ratio ranges taught by this specification).
  • the viscosity characteristics of the final formulated lubricant composition may be optimized by blending aliquots of all ingredients (with optional additives) and then making slight adjustment of viscosity by appropriate addition of any of ingredients (A), (B) or (C).
  • polyol ester ingredients (A) and (B) described in the preceding section may be prepared by conventional esterification methods. Suitable conventional esterification techniques are described in U.S. Patent 3,778,454 column 4, lines 9 through 75 and column 5, lines 1 through 12, the disclosure which is incorporated herein by reference.
  • Ingredient (A) of the composition of the invention is conveniently prepared by full esterification of trimethylolpropane (TMP) with a straight chain monocarboxylic acid or a mixture of straight chain monocarboxylic acid having from 8 to 12 carbon atoms.
  • TMP trimethylolpropane
  • Suitable acids for esterifying TMP to prepare ingredient (A) are n-octanoic acid, n-nonanoic acid and decanoic acid. Mixtures of straight chain C S -C 12 carboxylic acids may be used if desired.
  • Nonanoic acid is particularly preferred for esterifying TMP to give an ester oil suitable for ingredient (A).
  • Ingredient (B) of the composition of the invention is conveniently prepared by the full esterification of trimethylolpropane with a branched chain carboxylic acid of from 18 to 24 carbon atoms.
  • suitable monocarboxylic acids for the esterification of TMP to give ingredient (B) are isostearic acid; iso-octadecanoic acids, and the symmetrical branched chain acids of 18 or more carbon atoms such as described in U.S. Patent 4,144,183; Col. 4, lines 55-68 and Col. 5, lines 1-39. Mixtures of iso C 18 - 24 monocarboxylic acids may be used.
  • Trimethylolpropane tri-isostearate is a particularly preferred ester oil for use as ingredient (B).
  • Ingredient (C) of the composition of the invention is polyalphaolefin having a viscosity of from about 3 to about 6 cSt (viscosity measured at 98.9°C.).
  • Polyalphaolefins of suitable viscosity may be prepared by a variety of cracking or oligomerization processes such as described in the Encyclopedia of Chemical Technology, Third Ed., Vol. 16, pages 487-492, ISBN 0-471-02069-9, the disclosure of which is incorporated hereby by reference.
  • Olefin oligomers which are in the range of C 6 to C 20 fractions (as described on p. 492 of the Encyclopedia of Chemical Technology reference, supra) are preferred for use as ingredient (C).
  • a polyalphadecene having a viscosity of about 4 cSt is particularly preferred in the practice of this invention.
  • the balance of the lubricant composition may optionally comprise conventional lubricant additives such as corrosion inhibitor, an antioxidant, an antiwear agent, a metal deactivator, an antifoam agent, and a dye. It is a preferred aspect of this invention that the lubricant composition contain no polymeric viscosity index improver or seal swell agent. Viscosity improvers are unnecessary to attaining the required physical propeties of the lubricant composition and provide a site for degradation.
  • the synthetic transmission lubricant composition of this invention is obtained by uniformly mixing the essential ingredients (A), (B) and (C) with any selected optional ingredients.
  • the solution of some optional ingredients is assisted by use of elevated temperatures.
  • the final formulated composition may be filtered or otherwise treated to remove particulate contaminants.
  • the synthetic lubricant composition of this invention may be employed in a method to lubricate machinery. Lubrication of machinery is achieved by contacting the moving parts of a machine with lubricant composition. The lubricant may be contacted with the machine parts by such conventional means as spraying, dipping or padding. This method of lubrication finds particular utility for treating the metal parts of a vehicle transmission.
  • the blended transmission lubricant composition of this Example had the following physical properties:
