Be used for lubricant base oil of the present invention and can be selected from I class, II class, III class, IV class and V series lubricant agent base oil and composition thereof.Lubricant base oil of the present invention comprises the synthetic lubricant base oil, for example Fisher-Tropsch derived lubricant base oil, and the mixture of non-synthetic lubricant base oil and synthetic lubricant base oil.The specification that has shown the lubricant base oil that in API Interchange Guidelines (API Publication1509), uses sulphur content, saturated compound content and viscosity index definition in the following table 1:
Table 1
The facility of producing I series lubricant agent base oil typically extracts component than low-viscosity index (VI) with solvent, makes the VI of stock oil bring up to required specification.These solvents are phenol or furfural typically.Solvent extraction obtains having less than 90% saturated compound with greater than the product of 300ppm sulphur.Most of lubricant output are I class category in the world.
The facility of producing II series lubricant agent base oil typically use hydrotreatment for example hydrocracking or harsh hydrotreatment so that the VI of stock oil brings up to specification value.The use of hydrotreatment typically makes saturated compound content bring up to be higher than 90, and sulphur content is dropped to be lower than 300ppm.About 10% lubricant base oil production is II class category in the world, and about 30% output of the U.S. is the II class.
The facility of producing III series lubricant agent base oil is typically produced the product of very high VI with the wax isomerization technique.Because initial charge is wax vacuum gas oil (VGO) or contains all saturated compounds and the wax of a small amount of sulphur, so having, the III series products is higher than 90 saturated compound content, be lower than the sulphur content of 300ppm.For wax isomerization method was produced III series lubricant agent base oil, fischer-tropsch wax was desirable charging.In the world in the lubricant supply only sub-fraction be III class category.
Low polyacene derivative by positive structure alhpa olefin obtains IV series lubricant agent base oil, and is referred to as polyalphaolefin (PAO) lubricant base oil.
V series lubricant agent base oil is all other lubricant base oils.This class comprises that the lubricant base oil of synthesizing ester, silicone lubricant, halogenation and VI value are lower than 80 lubricant base oil.With regard to the application's book, V series lubricant agent base oil does not comprise synthetic vinegar class and silicone lubricant.V series lubricant agent base oil is typically by for the production of the same procedure of I class and II series lubricant agent base oil but not too prepared by oil under the exacting terms.
The synthetic lubricant base oil meets API Interchange Guidelines, but, ethylene oligomerization synthetic by fischer-tropsch, positive structure alhpa olefin is oligomeric or boiling point is lower than C
10Olefin oligomerization prepare.
The lithium composite thickening agent that is used for grease composition of the present invention can be any known lithium composite thickening agent.For example, the agent of lithium composite thickening can comprise derive self-contained epoxy group(ing) and/or the unsaturated part of olefinic (unsaturation) lipid acid lithium soap and derived from the dilithium salt of unbranched dicarboxylic acid and/or in one embodiment derived from hydroxyl substituted carboxylic acid salicylic lithium salts for example.
Described thickening material can be C
12-C
24The mixture of the lithium soap of hydroxy fatty acid and single lithium salts of boric acid and can comprise for example salicylic lithium salts of the second hydroxycarboxylic acid.
Described mixture can comprise C
12-C
24The lithium soap of hydroxy fatty acid thickening material antioxidant, this lithium soap comprise an alkali metal salt and dioxime (diozime) compound of hydroxy-benzoic acid.An alkali metal salt of hydroxy-benzoic acid comprises Whitfield's ointment two lithiums.
This mixture can be the lithium soap as the combination of following material: C
4-C
12The dilithium salt of dicarboxylic acid is nonane diacid two lithiums for example, 9-, 10-or 12-hydroxyl C
12-C
24The lithium soap of lipid acid is the 12-hydroxy lithium stearate for example; With the lithium salts that in lubricating grease, is formed by the second hydroxycarboxylic acid original position, wherein-OH be connected with carbon atom apart from no more than 6 carbon of carboxyl and wherein any in those groups can partly be connected with aliphatic series or the aromatics of described material.
Perhaps, the lithium mixture can comprise compound lithium soap thickening material, C
3-C
14The lithium salts of hydroxycarboxylic acid and the combination of thiadiazoles.Described lubricating grease can also be randomly and is preferably contained other antioxidant, preferred amines type or phenol type antioxidant, most preferably amine type antioxidant.
In one embodiment, the agent of lithium composite thickening only is for example lithium salts of oxystearic acid of carboxylic acid, particularly hydroxycarboxylic acid.Such thickening material can be for example by making a hydronium(ion) oxidation lithium (lithium hydroxyl monohydrate) and oxystearic acid react to prepare.
Described lubricating grease can comprise main amount for example greater than the base oil of 50 % by weight, and minor amount is namely less than thickening material and any other additive of 50 % by weight.Certainly, lubricating grease of the present invention can contain any other typical grease additive such as rust-preventive agent, dinonyl naphthalene sulfonate barium (barium dinonyl naphtheline fulfonate), sequential adjustment agent (order modifier), tackiness agent, extreme pressure agent, minute aqua, dyestuff etc.Typical additive and their functional description are in Modem Lubricating Greases by C.J.Boner, among Scientific Publication (G.B.) Ltd.1976.
For the present invention, multipolymer is as the additive particularly important.The multipolymer that multipolymer can be based on hydrocarbon is the multipolymer of vinylbenzene and divinyl or ethene and propylene for example.In one embodiment, copolymer additives is the multipolymer of vinylbenzene and divinyl.Find to be used in combination on a small quantity with the agent of lithium composite thickening, for example 2-6 % by weight or 2-5 % by weight, perhaps such multipolymer of 3-4 % by weight in another embodiment makes thickening efficiency raising 25-50%.
Bringing the weight of the base oil in the lubricating grease matrix when grease thickening definitions of efficiency is the thickening material of per unit weight into, is for example crucial deciding factor of penetration degree, shear stability and water-repellancy and preparation cost of lubricating grease mechanical property.The combination of the multipolymer of vinylbenzene and divinyl and the agent of lithium composite thickening allows to use relatively large base oil, thereby promotes grease thickening efficient, and keeps simultaneously good mechanical property.This result is more economical again effective lubricating grease also.
This analog copolymer of vinylbenzene and divinyl is commercially available.For example, V-211 derives from Functional Products, Inc.of Macedonia, the vinylbenzene of Ohio and the multipolymer of divinyl.This multipolymer is the white that is instantly-soluble-yellow rubber powder.These multipolymers of vinylbenzene and divinyl can be combined with other polymkeric substance use, but they must be present in the grease composition of the present invention.
By being used in combination styrene/butadiene copolymers with the agent of lithium composite thickening, obtained higher thickening efficiency.Described efficient, it relates to the amount of bringing the base oil in the lubricating grease matrix when still realizing good mechanical properties into, can improve at least about 25 % by weight, about 35 % by weight or at least about 50 % by weight.Shown this class grease composition show at least about 290, at least about 300 with even at least about 310 working needle in-degree performance.Described composition can be used for any Automobile Grease or industrial grease is used.For example, grease composition can be used for wheel bearing, automobile chassis or is used for oilgear.
Following examples help to illustrate the present invention and advantage thereof, still should not think to limit the scope of the invention.
