Definitions

  • the present invention relates to lubricant base stock blends. More particularly, the present invention is directed toward base stocks having unexpectedly improved resistance to deposit formation, improved solubility for lubricant additives, degradation products and enhanced demulsibility.
  • Synthetic lubricant base stocks prepaied by oligomerizing one or more alpha olefins are well known commercially available materials that have low pour points and high viscosity indices.
  • Lube products employing these poly- alpha-olefins (PAO's) typically are combined with a more polar co-base stock such as alkylated aromatic fluids or polyol esters or certain dispersant additives such as polyalkylene type additives.
  • alkylated aromatic base fluids such as alkylated naphthalene
  • PAO base fluids provides the fluid blend with improved hydrolytic stability but there remains a need to provide the blend with improved dispersancy.
  • PAO base fluids provide enhanced dispersancy but these additives form stable emulsions with water and degrade the hydrolytic stability of compositions employing them thereby limiting the use of the blend to applications where water ingress is not a problem.
  • polyol esters in PAO base fluids provides good dispersancy but poor hydrolytic stability.
  • one object of the present invention is to provide a lubricant product of improved dispersancy along with good demulsibility and hydrorytic stability.
  • the present invention is a synergistic combination of synthetic fluids useful as lubricant base stock blend and comprising about 10 wt% or more of a PAO fluid; about 1 wt% or more of an alkylated aromatic fluid and about 1 wt% or more of an aromatic ester.
  • the lubricant base stock comprises:
  • Figure 1 is a graphic comparison of the storage stability of a commercial lubricant composition with one using a base stock of the invention.
  • Figure 2 graphically illustrates the deposit control property of a base stock of the invention.
  • Figure 3 graphically compaies the water demulsibility of a commercial composition with one using a base stock of the invention.
  • Figure 4 graphically compaies the oxidative and hydrolytic stability of two base stocks formulations of the invention with two others.
  • a blend of three lubricant fluids viz a PAO, an alkylated aromatic and an aromatic ester has improved solvency for lube additives such as oxidation and rust inhibitors, metal passivators and the like.
  • the blend also has improved hydrolytic stability, dispersancy and resistance to deposit formation without degrading demulsibility making the blend useful in a wide range of industiial applications.
  • fully formulated lubricant compositions employing the base stock of the present invention are especially suitable for use in applications where there is the potential for water or moisture ingress such as oils used in combined cycle turbines, paper machinery, rod mills and the like.
  • the blended base stock of the invention includes at least about 10 wt% of a PAO fluid.
  • the blend will comprise from about 10 wt% to about 98 wt% of the PAO fluid, based on the total weight of the blend.
  • the blend will comprise from 60 wt% to 95 wt%, and more preferably from 80 wt% to 85 wt%.
  • PAO fluids and their preparation are well known in the ait. Those PAO's suitable in the practice of the present invention may be derived from C2 to about C32 alpha olefins with Cg to about C ⁇ _ alpha olefins being preferred.
  • the PAO will have a viscosity in the range of about 3 cSt to about 300 cSt at 100°C.
  • the preferred PAO a viscosity will, of course, depend upon factors such as the nature and amount of the other components used in the blend and the intended end use for the lubricant base stock blend.
  • the base stock blend of the present invention also includes a alkylated aromatic compound such as alkylated benzene, naphthalene, anthracene, biphenyl and the like.
  • alkylated aiomatics and their method of preparation are well known in the ait. Suitable alkylated aiomatics are those having one or more short chain alkyl groups of from 1 to about 8 carbon atoms.
  • the preferred alkyl aiomatics will have viscosities in the range of about 3 cSt to about 300 cSt at 100°C.
  • the alkylated aiomatics will comprise about 1 to about 59 wt% of the total blend, preferably about 5 wt% to about 35 wt% and more preferably about 10 wt%.
  • the base stock of the present invention also includes an aiomatic ester fluid.
  • aiomatic ester fluid Common lubricant grade aiomatic esters such as phthalate esters, mono- and diesters, polyol ester and ester with tails contain S, N and O suitable in the blend of this invention are commercial available materials typically formed by reacting an organic acid or anhydride with straight or branched alcohols. Such esters have viscosities in the range of about 4 cSt to about 30 cSt at 100°C.
  • the amount of aromatic ester employed in the base stock blend will be from about 1 wt% to about 75 wt%, and preferably from about 2 wt% to about 25 wt% of the total blend, with about 5 wt% to 8 wt% being more preferred.
  • An advantageous feature of the base stock blend of the present invention is its ability to solubilize additives such as heterocyclic rust inhibitors, antioxidants, antiwear agents, corrosion inhibitors and the like.
  • additives such as heterocyclic rust inhibitors, antioxidants, antiwear agents, corrosion inhibitors and the like.
  • antioxidants suitable for use in the base stock blend specific mention is made of aminic and phenolic type antioxidants.
  • Suitable antiwear agents include alkylated triphenyl phosphates, phosphorophites, diorganodithiocarbamates and the like.
  • a base stock according to the present invention comprising 84 wt% of a PAO (6 cSt at 100°C) 10 wt% of an alkyl aromatic (alkylated naphthalene) fluid (5 cSt at 100°C) and 6 wt% of an ester fluid (diisooctylphthalate) was used in preparing a fully formulated lubricant composition (Formulation A) by blending the base stock with the following additives:
  • composition was maintained at 100°C for 16 weeks without any evidence of haze or floe. Haze or floe, of course, is indicative of additive insolubility.
  • a commercially available composition comprising a 6 cSt at 100°C PAO, 20 wt% diisodecylphthalate ester and substantially the same amounts of similar type additives of Formulation A after six weeks displayed a trace of haze and moderate floccing.
  • Figure 1 graphically presents the results of the tests and illustrates the improved solubility that the base stock of the invention has for lubricant additives.
  • the deposit control of the base stock of the invention was compared to a commercially available lubricant composition (Comparative 2) by subjecting Formulation A of Example 1 and Comparative 2 to the Cincinnati Macliine Thermal Test A.
  • the Comparative 2 composition has a PAO base fluid, typical additives and 1.0 wt% of a dispersant.
  • the results of the text are graphically shown in Figure 2. As can be seen under the text conditions Formulation A exhibited excellent low deposit formation. Moreover, when the test was modified by raising the test temperature from 275°F to 350°F at the end of 168 hours visual inspection of the samples showed that the Formulation A had far less deposit formation.
  • Formulation A of Example 1 and a commercial lubricant composition were subjected to the ASTM-D 1401 demulsibility test.
  • Comparative 3 was a PAO based lubricant containing 1.0 wt% of a polyalkylene dispersant. The results of the tests are shown in Figure 3.
  • Formulation A with the base stock of the invention showed complete water sepaiation within 10 minutes. Fo ⁇ nulation A, of course, did not contain a demulsf ⁇ er additive.
  • This example compaies the oxidative and hydroytic stability, as determined by ASTM D 943 TOST life test, of two base stocks of the invention (A and B) with two other base stock (C and D).
  • Base stock A comprised 80 wt% PAO (6 cSt at 100°C); 10 wt% of an alkylated naphthalene (5 cSt at 100°C) and 6 wt% an ester fluid (diisooctylphthalate).
  • Base stock B differed from A in that the ester was a 50:50 mixture of ditridicyl phthalate and terephtalate ester.
  • Base stock C and D used the same PAO as A and B.
  • the alkylated aromatic fluid of C was the same as in A and B while the ester of D was a trimellitatte ester.
