Definitions

• Polyphenylene ether lubricants represent very stable organic structures which meet the needs of jet engines, high temperature hydraulic systems, nuclear power plants, and as the fluid component of high temperature greases. Although this class of lubricant is thermally and oxidatively stable, they can cause significant wear of high-alloy steels that are typically used in supersonic and hypersonic aircraft jet engines. Polyphenylene ether lubricants have been proposed which contain various additives for a variety of purposes. A representative, non-limiting listing of additives which have been proposed is as follows:
• the present invention relates to a polyphenylene ether lubricant comprising an effective amount of a hydrocarbyl bis(dihydrocarbylphosphate) compound as an anti-wear additive.
• hydrocarbyl bis(dihydro-carbylphosphate) compounds have been used as additives in fuels for internal combustion engines (U.S. Patent No. 3,254,973), as extreme pressure and anti-wear additives in oleaginous or petroleum based lubricants (U.S. Patent No. 3,492,373; also see U.S. Patent No. 3,360,467 at Col. 1, line 58 to Col. 2, line 2, for the non-predictable behavior of such additives when in a polyphenylene either fluid), and as a low flammability hydraulic oil, in general (U.S. Patent No. 4,212,832).
• the polyphenylene ether lubricant of the present invention comprises, as the base stock, a polyphenylene ether of the formula Ar-O-[Ar-O] n -Ar where Ar stands for a phenyl ring, n is a whole number of generally from 2 to 5.
• This class of lubricant is well known to persons of ordinary skill in the art with the following patents, which are incorporated herein by reference, providing further disclosure: U.S. Patent Nos. 3,360,467; 3,423,469; 3,476,815; 3,704,277; and 3,706,668.
• the polyphenylene ether base stock will comprise from about 90% to about 99.5%, by weight, of the entire lubricant composition.
• hydrocarbyl (bisdihydrocarbylphosphate) compounds which are used as an anti-wear additive with the previously described polyphenylene ether base stock are of the formula where R is either unsubstituted or substituted hydrocarbyl such as alkyl or aryl and A is a bridging group containing alkylene, haloalkylene, arylene, two arylene groups joined by a bridging group (e.g., -C(CH3), -SO2 or -CO), or a bridging group containing biarylene.
• a bridging group e.g., -C(CH3), -SO2 or -CO
• Such compounds are a known class of flame retardant in polymers and, as indicated above, have had some degree of use in certain fuel and lubricant compositions.
• Preferred R groups are phenyl with A also being phenylene, such as derived from a monoaromatic diol, such as either resorcinol or hydroquinone.
• phenylene such as derived from a monoaromatic diol, such as either resorcinol or hydroquinone.
• diphosphate additive is present in a relatively low amount such as about 0.1% to about 10%, by weight of the composition.
• the polyphenylene ether lubricants of the present invention can contain other additives, particularly those recognized for use in fluids of that type. Inclusive of such additives are pour point depressants, viscosity index improvers, dyes, rust inhibitors, other anti-wear additives, and the like.
• This Example sets forth the wear data at various temperatures and loads (Four-Ball Wear scar at 600 rpm for two hours, two runs) for a control polyphenylene ether fluid and similar fluids containing certain bisphosphate additives:
• NGBDP neopentyl glycol bis(diphenyl phosphate) additive
• BABDP bisphenol A or resorcinol derived bisphosphates
