Definitions

  • the present invention relates to synthetic lubricant compositions having good oxidation resistance, compatibility with petroleum lubricants, good corrosion resistance and hydrolytic stability, and being suitable for use in air compressors, turbines, hydraulics, gears, bearings, fuel engines, textile machinery and greases.
  • lubricant possessing a variety of characteristics are required for use in different applications. Characteristics which are essential to certain applications include lubricity, seal compatibility, low volatility, low pour point temperature, anti-wear/extreme pressure, high thermal conductivity, thermal stability, corrosion resistance, hydrolytic stability, varnish and deposit control, and oxidation stability or resistance. Oxidation stability and related varnish/deposit control is very important for most applications and is essential for a good general purpose, long life synthetic lubricant.
  • the most common types of synthetic lubricant base stocks are polyalphaolefin (referred to as "PAO"), esters (referred to as diesters), polyol esters and polyalkylene glycols.
  • esters are added at 20-30% to PAO to improve additive solubility and varnish/deposit control such as in synthetic motor oil lubricants, and at 20-30% to polyalkylene glycols to improve corrosion protection such as in air compressor lubricants.
  • Esters are commonly used independently but perform best at higher temperatures or in clean, low humidity applications such as in chain lubricants and aircraft turbine lubricants. Because of their relatively poor hydrolytic stability and chemical resistance, they can cause premature degradation. Degradation of the ester through oxidation or hydrolysis by moisture results in corrosive acidic by-products.
  • esters When esters are blended with either PAO or polyalkylene glycol, hydrolytic stability and chemical resistance of the blend is reduced and therefore the life of the lubricant based on that blend.
  • Polyglycols by themselves exhibit excellent varnish/deposit control and hydrolytic stability and produce little acidic by-products upon oxidation. However, they exhibit very poor corrosion protection and they generally are not compatible with petroleum lubricants.
  • PAO's by themselves, offer good oxidation stability; however, they exhibit poor solubility characteristics, which results in poor seal compatibility, additive solubility, and varnish/deposit control.
  • PAO and ester blends are also commonly found in lubricants formulated for hydraulics, turbines, bearings, gears, and general purpose lubricant applications such as Mobil's SHC series of synthetic lubricants. Overall, such formulations are good, cost effective lubricants. However, oxidation resistance, varnish/deposit control, and resistance to moisture and combustion by-products or chemicals needs to be improved to extend lubricant life. Also, efforts to reduce additive content and improve pollution controls is intensifying.
  • alkylated aromatic compounds such as those disclosed is US Patent 5,457,254, US Patent 5,414,174, US Patent 5,302,769, US Patent 5,235,115, US Patent 5,191,135, US Patent 5,191,134, US Patent 5,177,284, US Patent 5,171,904, US Patent 5,043,508, and US Patent 5,034,563. These are, however, more expensive and do not offer equivalent oxidation stability, varnish/deposit control, seal compatibility, and lubricity, and are not generally as suitable per se with applications such as compressors and the like.
  • ester based lubricants perform very well in jet turbines, high temperature chains, and other applications where high temperatures or extreme cleanliness eliminates moisture and chemical contaminants. Performance of esters in industrial applications such as air compressors, hydraulics, and gears is marginal for a synthetic lubricant due to moisture and chemical contaminants and poor seal compatibility.
  • lubricants include silicones, polyaryl (biphenyl) ethers, fluorinated organics, and phosphate esters that are extremely expensive and are suitable to only very special applications where unique performance characteristics are required and cost is not of foremost concern.
  • the present invention is premised upon the realization that a lubricant exhibiting excellent lubricity, oxidation resistance, hydrolytic stability, and varnish/deposit control can be formed by combining a polyalkylene glycol with an alkylated aromatic compound or an alkoxylated aromatic compound.
  • a lubricant is relatively inexpensive, but retains all the advantages of the polyalkylene glycol, in particular, excellent lubricity, hydrolytic stability and varnish/deposit control. Further, this overcomes the deficiencies of polyalkylene glycols, providing compatibility with various types of petroleum lubricants, good corrosion resistance, and drastically improving oxidation resistance.
  • the present invention provides a lubricant composition
  • a lubricant composition comprising a polyalkylene glycol compound in combination with an aromatic compound selected from the group consisting of alkylated aromatic lubricants and alkoxylated aromatic lubricants in an amount effective to improve the oxidation resistance of said polyalkylene glycol compound.
  • the lubricant of the present invention is formed from one or more alkylated naphthalenes in combination with one or more polypropylene or polybutylene glycols initiated preferably with either an alkyl or aromatic alcohol.
  • the present invention is a lubricant or base stock blend formed by combining a polyalkylene glycol with an alkylated or alkoxylated aromatic composition.
  • the aromatic portion of the aromatic composition can be a phenyl group, a naphthyl group or a fused aromatic compound such as a bis-phenyl or phenathrene group.
  • the aromatic moeity is desirably substituted with one or more alkyl groups. Specifically, the aromatic group is substituted with at least one alkyl group which is C 3 alkyl or higher, generally C 5 - C 24 .
  • the aromatic group can be substituted with an alkoxy group to form, for example, an alkoxy naphthalene wherein the alkyl portion of the alkoxy group is C 3 -C 24 .
  • the method of manufacturing such compositions is relatively well known but is disclosed in particular in US Patent 5,191,135, US Patent 5,177,284, US Patent 5,191,134, and US Patent 5,043,508.
  • the aromatic composition will be an effective lubricant and will have a viscosity of at least about 10-220 cSt at 40° C.
  • One preferred alkylated aromatic is a monoalkylated naphthalene (C 16 ).
  • Mobil Chemical Co. sells such an alkylated naphthalene under the trademark Mobil MCP917. Di and tri alkylated naphthalenes and mixtures are also available and can be used.
  • the level of the alkylated or alkoxylated aromatic compound will be from 5% to 90% by weight of the lubricant composition of the present invention and preferably from 10% to 30% by weight.
  • the remaining primary portion of the lubricant, other than minor lubricant additives and the like, known to the art of lubrication, will be the polyalkylene glycol.
  • the polyalkylene glycol can be manufactured with a single or a random or block mixture of two or more of the following oxides: ethylene, propylene, 1-2 or 2-3 butylene, hexa-1-ene, or dodec-lene glycols initiated with either an alkyl or aromatic alcohol.
  • the polyalkylene glycol, also referred to as polyoxyalkylene glycol or polyglycol ethers will generally be defined by the following formula: R-[- ( A )n - R' ]m wherein
  • the viscosity of the polyalkylene glycols of the present invention typically ranges from about 10 to 680 centistokes (cSt) at 40° C, depending on the lubricant application viscosity requirements.
  • viscosity refers to each polyalkylene glycol used in the composition on an individual basis. Those skilled in the art can determine the viscosities of mixtures of PAGs suitable for use in accordance with the present invention.
  • Ethylene oxide, propylene oxide, and butylene oxide are the three most common commercially available alkylene oxides used in the manufacture of polyalkylene glycols. These alkylene oxides are polymerized singly or in random or block combinations with one or more other alkylene oxides. They are initiated most often with a hydroxyl or an alkyl or aryl alcohol such as butanol or nonylphenol, respectively.
  • a preferred polyalkylene glycol is that initiated with an alkyl aryl alcohol such as a C 3 -C 20 alkyl phenol with the nonylphenol initiated polyalkylene glycol preferred.
  • polyalkylene glycol Preferably about 0-100%, preferably 5-80% and most preferably 20-60% of the polyalkylene glycol will be the alkyl aryl alcohol initiated poly alkylene glycol Branched polyethers of alkylene oxides, formed from trimethylol or other polyol initiators are also commercially available. Polyalkylene glycols are commonly used as surfactants, process chemicals, and lubricants. Thus, the present invention will incorporate from 10% to 95% by weight of the polyalkylene glycol, and preferably from 60% to 90% by weight.
  • the present invention can incorporate the following additives in well known standard amounts: anti-wear/extreme pressure additives, antioxidants, metal deactivators, detergents, dispersants, corrosion inhibitors, defoamers, dyes or such additives as may be required for the lubricant application.
  • the lubricant of the present invention can also include 1% to 20% of various components which may affect various physical characteristics of the lubricant such as viscosity, Viscosity index, solvency, and low temperature characteristics and the like.
  • Such components would include polyalphaolefins, polyol esters and diesters, silicone lubricating fluids, as well as modified or grafted versions such as esters grafted onto polyalphaolefins.
  • Other polymer fluids which are typically used in the manufacturing of lubricants can also be incorporated such as polyisobutylene, polybutylene, olefinic copolymers, styrene and styrene copolymers, branches parafinic polymers and polymethacrylates. These are all components that are well known for use with motor oils and industrial lubricants.
  • the lubricant of the present invention is formed by simply adding the base fluid and additive components together in a blender and mixing until completely solubilized. Due to their nature, they will remain solubilized without further mixing or treatment.
  • preferred alkylated aromatic compounds include: alkylated naphthalene sold by Mobil under the trade designation Mobil MCP 917.

  • oxidation resistance of the two lubricants in the present invention are vastly superior to the two commercial lubricants which represent the industry standard for synthetic air compressor lubrication.
  • the test is stopped after 30 hours for Sullube 32 and Summa Rotar after a 25 PSI pressure decrease in the test bomb.
  • the test is also stopped if the TAN values of the lubricant exceed 10.0 because this can result in excessive corrosion of the test bomb copper catalyst.
