Abstract
The present disclosure relates to a lubricant composition comprising a lubricant, a first ionic liquid which is soluble in polyalphaolefin and a second ionic liquid which is insoluble in polyalphaolefin. By using the two different ionic liquids, the technical properties of the lubricant compositions can be improved.
Claims19
A lubricant composition comprising:
- a) a lubricant, in particular containing a non-polar basic oil,
- b) a first ionic liquid which is soluble in polyalphaolefin (PAO), in particular in PAO 400/40, prepared from 1-decene as a monomer component, and
- c) a second ionic liquid which is insoluble in polyalphaolefin (PAO), in particular in PAO 400/40, prepared from 1-decene as a monomer component.
A lubricant composition comprising:
- a) a lubricant containing a basic oil selected from the group consisting of mineral oils, polyalphaolefins, alkylated naphthalenes, alkylated diphenyl ethers, alkylated benzenes, copolymers of alkenes, preferably LAO with unsaturated esters, and mixtures thereof, in particular selected from the group consisting of polyalphaolefins and alkylated diphenyl ethers and mixtures thereof,
- b) a first ionic liquid whose anion is selected from the group consisting of dialkyl phosphate, preferably bis(2-ethylhexyl)phosphate, dialkylphosphinate, preferably bis(2,4,4-trimethylpentyl)phosphinate, carboxylate, preferably decanoate, docusate and mixtures thereof, and
- c) a second ionic liquid whose anion is selected from the group consisting of bis(perfluorosulfonyl)imide, tris(perfluoroalkyl sulfonyl)methide, tris(perfluoroalkyl)trifluorophosphate, bisfluorosulfonylimide and mixtures thereof.
