Definitions
- the present invention relates to a lubricant composition. More specifically, the present invention relates to a lubricant composition containing specific composite ester in which low frictional properties and low abrasive properties are compatible.
- a lubricant a lubricant composition
- low friction has been required from the viewpoint of reducing an energy loss.
- a reduction in fuel consumption has been strongly required from the viewpoint of reducing discharge of carbon dioxide gas, and attaining low friction in engine oil becomes extremely important.
- a fluid lubrication state in which fluid oil exists between friction surfaces a boundary lubrication state in which friction surfaces are in contact with each other, and thus, are easily abraded, and a mixed lubrication state which is an intermediate state between the states described above are known as a frictional state.
- a lubricant composition for an internal combustion engine oil film shortage easily occurs at the time of performing engine initiation, and thus, the boundary lubrication state is easily formed.
- a viscosity of the lubricant composition is high from the initiation until an oil temperature increases, and thus, viscosity resistance is large, and an energy loss occurs.
- the lubricant composition is required to exhibit excellent friction properties at various temperatures and in various load regions.
- the lubricant composition contains base oil and various additives.
- the base oil include e.g. mineral oil obtained from crude oil, ester-based oil which is chemically synthesized, fluorine-based oil, and poly ⁇ olefin-based oil.
- the ester-based oil is preferably used e.g. in a jet plane, automobile engine oil, and grease, from the viewpoint of e.g. a low pour point, a high viscosity index, a high ignition point, excellent lubrication properties, and biodegradability.
- ester-based oil is used as base oil or an additive.
- various esters such as monoester obtained from a reaction between an aliphatic monocarboxylic acid and monohydric alcohol; diester obtained from a reaction between an aliphatic dicarboxylic acid and monohydric alcohol; polyol ester obtained from a reaction between polyhydric alcohol and an aliphatic carboxylic acid; and composite ester obtained from a reaction between polyol, a polybasic acid, and an aliphatic monocarboxylic acid have been disclosed ( JP2002-097482A , JP2005-154726A , JP2005-232434A , JP2005-213377A , JP2005-232470A , JP2001-501989A , JP2001-500549A , JP2001-507334A , and JP2002-530476A ).
- US 2012/184474 describes a complex alcohol ester composition useful as a lubricant agent which includes a polyester in which at least two molecules of a polyol are linked through at least two ester bonds via at least one molecule of a polybasic acid and at least a part of the non-linked side chain ends of the polyol carry a group.
- the lubricant composition is required to exhibit excellent friction properties at various temperatures and in various load regions.
- excellent friction low friction
- a reduction in viscosity resistance of the lubricant composition that is, low friction in the fluid lubrication state according to low viscosity is effective, but in a case where the lubricant composition has a low viscosity, a device deteriorates due to abrasion in the boundary lubrication state.
- An object of the present invention is to provide a lubricant composition in which low frictional properties and low abrasive properties are compatible at various temperatures and various loads.
- the lubricant composition of the present invention can exhibit low frictional properties and low abrasive properties at various temperatures and various loads.
- the lubricant composition of the present invention can excellently exhibit a low viscosity, low frictional properties in a fluid lubrication state, and low abrasive properties even in a boundary lubrication state such as a high temperature and a high load.
- a lubricant composition of the present invention relates to a lubricant composition containing composite ester (A) produced by condensation of at least trivalent or more polyol (a1), a mixture (b1) of at least one of a polymerization reaction mixture of an unsaturated fatty acid having 18 to 22 carbon atoms which contains at least 75 mass% of a divalent carboxylic acid having 36 to 44 carbon atoms or a mixture obtained by performing hydrogenation with respect to the polymerization reaction mixture, and monool (c1) represented by Formula (1) described below is condensed.
- a feed ratio of the number of moles of a hydroxyl group of (a1)/the number of moles of a carboxylic acid of (b1)/the number of moles of a hydroxyl group of (c1 is 1/1.5 to 2.0/0.7 to 1.5, and the content of the composite ester A is 0.1 to 5 mass% with respect to the total mass of the lubricant composition.
- R represents a branched alkyl group having greater than or equal to 10 carbon atoms.
- the composite ester A used in the lubricant composition of the present invention is obtained by feeding and performing a condensation reaction an (a1) component to a (c1) component such that the number of moles of the hydroxyl group of a1/the number of moles of the carboxylic acid of (b1)/the number of moles of the hydroxyl group of (c1) becomes 1/(1.5 to 2.0)/(0.7 to 1.5), preferably becomes 1/(1.55 to 1.9)/(0.8 to 1.4), and more preferably becomes 1/(1.60 to 1.8)/(0.8 to 1.3).
- a feed ratio of P/Q is preferably 1/0.7 to 1.0, is more preferably 1/0.75 to 0.95, and is even more preferably 1/0.8 to 0.9. That is, it is preferable that composite ester A can be obtained by feeding each of the components such that a feed ratio of the total number of moles of the hydroxyl group/the total number of moles of the carboxylic acid is in the range described above.
- each of the components is fed at a specific ratio, and is condensed, and thus, e.g. a degree of crosslinkage, a viscosity, an acid value, and a residual amount of monool, of the obtained composite ester A can have optimal values. For this reason, it is possible to suppress abrasion by only adding a trace amount of the composite ester A into e.g. base oil, and thus, the lubricant composition can exhibit abrasion resistance while maintaining viscosity properties of the base oil.
- excellent friction properties can be obtained in both of a fluid lubrication state and a boundary lubrication state.
- the content of the composite ester A may be 0.1 to 5 mass%, is preferably 0.3 to 3 mass%, and is more preferably 0.5 to 2 mass%, with respect to the total mass of the lubricant composition.
- excellent lubrication properties are exhibited by only adding a small amount of the composite ester A into the lubricant composition.
- the trivalent or more polyol (a1) (the (a1) component or also simply referred to as (a1)) is a compound containing greater than or equal to 3 alcoholic hydroxyl groups and/or greater than or equal to 3 phenolic hydroxyl groups in the molecules, is preferably a compound containing greater than or equal to 3 alcoholic hydroxyl groups, and is more preferably a compound containing 3 to 6 alcoholic hydroxyl groups.
- Preferred trivalent or more polyol (a1) is alcohol represented by Formula (a1-1) described below. Z( ⁇ OH) m1 Formula (a1-1)
- Z represents an m1-valent linking group
- m1 represents an integer of greater than or equal to 3, is preferably 3 to 6, and is more preferably 3 or 4.
- Z is preferably an aliphatic linking group, and is more preferably an alkylene linking group which may be linked by an oxygen atom.
- the number of carbon atoms of the alkylene linking group is preferably 2 to 20, is more preferably 2 to 15, is even more preferably 3 to 10, and is particularly preferably 5 to 7.
- Z is a linking group having a neopentyl partial structure represented by Structural Formula (Z-1) described below from the viewpoint of reducing friction at a high temperature.
- trivalent or more polyol (a1) include trivalent polyol such as trimethylol ethane, trimethylol propane, and glycerin, tetravalent polyol such as pentaerythritol, ditrimethylol ethane, and ditrimethylol propane, and pentavalent or more polyol such as dipentaerythritol, trimethylol ethane and trimethylol propane are particularly preferable.

- tetravalent polyol such as pentaerythritol, ditrimethylol ethane, and ditrimethylol propane
- pentavalent or more polyol such as dipentaerythritol, trimethylol ethane and trimethylol propane are particularly preferable.
- the mixture (b1) of at least one of the polymerization reaction mixture of the unsaturated fatty acid having 18 to 22 carbon atoms which contains at least 75 mass% of the divalent carboxylic acid having 36 to 44 carbon atoms or the mixture obtained by performing the hydrogenation with respect to the polymerization reaction mixture (the (b1) component or also simply referred to as (b1)) contains at least 75 mass% of the divalent carboxylic acid having 36 to 44 carbon atoms.
- the (b1) component preferably contains at least greater than or equal to 80 mass% of the divalent carboxylic acid having 36 to 44 carbon atoms, more preferably contains greater than or equal to 85 mass% of the divalent carboxylic acid having 36 to 44 carbon atoms, even more preferably contains greater than or equal to 90 mass% of the divalent carboxylic acid having 36 to 44 carbon atoms, and particularly preferably contains greater than or equal to 94 mass% of the divalent carboxylic acid having 36 to 44 carbon atoms.
