Description
Technical field
The present invention relates to a kind of lubricating oil, be specifically related to a kind of motorcycle special lube.
Background technology
The oil engine of new production, or the oil engine having changed cylinder sleeve, piston, piston ring, camshaft and rocking arm through overhaul, all must carry out break-in before dispatching from the factory.Because no matter meticulous through the how processing of the mating parts of the engine after new or overhaul, maintenance, surface still have visual inspection less than cutter trade, if without break-in, direct input heavy loading work, its piece surface will produce cut, shock etc. and damage phenomenon, thus reduces its work-ing life.Pass through break-in, between each kinematic pair of oil engine, particularly the parts two mating surface direct contact surface such as piston ring and cylinder sleeve, piston skirt and cylinder sleeve, bearing and axle journal, camshaft and rocking arm increases, and the ratio load of unit surface reduces, reach good contact, to set up normal coupling.Period of adjustment can improve surface of friction pair hardness simultaneously; its mechanism is: one is that surface of friction pair is under positive pressure effect; friction pair surface in contact produces viscous deformation and occurs work hardening phenomenon; the hardness ratio matrix hardness on surface is made to improve 3% ~ 5%; two is additive in lubricating oil and surface of friction pair generation friction chemical reaction; form protective membrane at surface of friction pair, the hardness of surface of friction pair is improved further.
The engine lubricating oil of traditional motorcycle is in use in the near future easily blackening, this is because engine lubricating oil is at lasting cleaning carbon particles, after the oxygen in air and engine oil work, the dense thick black carbon mud pellet attached bag of generation is overlayed in engine parts, when the running speed of engine and temperature higher, rate of decomposition is faster, this oxygenolysis is not only and causes damage to engine, and can block oil pipe, causes oil product to be sent to engine, add cost of equipment maintenance, reduce engine work-ing life.
Summary of the invention
For the problems referred to above that prior art exists, the object of the invention is: one prevents the problems such as engine cam heavy wear, scratch as far as possible in the period of adjustment, to the protection that engine is maximum, extend the lubricating oil in the work-ing life of engine.
For achieving the above object, the present invention adopts following technical scheme: a kind of motorcycle special lube, is characterized in that: the component comprising following mass fraction: base oil POA is 25-35 part; Naphthenic base oils is 55-60 part; Additive high base number calcium alkylbenzenesulfonate 0.4-0.6 part; Additive sulfur phosphorus fourth octyl group zinc salt 0.3-0.5 part; Thioether phenol type antioxidant 1.0-3.5 part, the terpolymer of ethene, propylene and non-conjugated diene hydrocarbon is 0.2-1.0 part, and the Mooney viscosity of this terpolymer is 25-35; Metal deactivator 1-3 part, this metal deactivator is phosphide or sulfide; Antioxidant 5-10 part, this antioxidant is 2,3-ditertbutylparacresol; Viscosity index improver 1-10 part, this viscosity index improver second is one or more in alkene-propylene copolymer, polymethacrylate, the hydrogenated isoprene multipolymer of star topology or vinylbenzene diene copolymer; Pour point depressant 0.06-1.2 part, this pour point depressant is one or more in alkylnaphthalene, poly-α-alkene, polymethacrylate, fumarate or toluylic acid; Kilfoam 0.001-0.02 part, this kilfoam gather in methyl-silicone oil, dimethyl silicone oil, acrylate and ether copolymer or silicon type and non-silicon type composite anti-foam agent one or more.
Relative to prior art, tool of the present invention has the following advantages: the present invention, by using the mixed base oil of PAO and naphthenic base oils composition, can ensure good viscosity index and high-wearing feature energy while control mixed base oil cost; In addition, added by the cooperation of additive, effectively can remove and be coated on dense thick black carbon mud pellet in engine parts; to the protection that engine is maximum; extend the work-ing life of engine, reduce the maintenance cost of equipment, for motor engine provides clean wear protection pattern.
Embodiment
Below the present invention is described in further detail.
A kind of motorcycle special lube, comprises the component of following mass fraction: base oil POA is 25-35 part, naphthenic base oils is 55-60 part, , additive high base number calcium alkylbenzenesulfonate 0.4-0.6 part, additive sulfur phosphorus fourth octyl group zinc salt 0.3-0.5 part thioether phenol type antioxidant 1.0-3.5 part, the terpolymer of ethene, propylene and non-conjugated diene hydrocarbon is 0.2-1.0 part, the Mooney viscosity (ML(1+4) 100 DEG C of this terpolymer) be 25-35, ethene, the terpolymer of propylene and non-conjugated diene hydrocarbon, i.e. terpolymer EP rubber (EPDM), for the viscosity index improver of lubricating oil, add oil product and can play the viscosity-temperature characteristics energy improving oil product, improve the viscosity index of oil product, oil product is made to have good low-temperature fluidity and high temperature lubricating, metal deactivator 1-3 part, this metal deactivator is phosphide or sulfide, metal deactivator is mainly used in the oxidation ratio reducing metallic contact effect, it is phosphide or sulfide, its mechanism of action forms inertia oil film in metallic surface, stop the generation of further oxidizing reaction, antioxidant 5-10 part, this antioxidant is 2, 3-ditertbutylparacresol, antioxidant is mainly used in stoping oxygenolysis, it is 2, 3-ditertbutylparacresol, it is shield phenol type radical termination agent, chain reaction when its working mechanism is by utilizing it to destroy hydrocarbon oxidation and delay oxidation of lubricating oil process, the hydrocarbon free radical produced with the hydrocarbon oxidization initial stage or the effect of hydrocarbon peroxide radical, make it to be converted into stable molecule, thus inhibit the formation of free radical, make it to be converted into stable molecule, thus inhibit the formation of free radical, chain reaction is interrupted.Viscosity index improver 1-10 part, this viscosity index improver second is one or more in alkene-propylene copolymer, polymethacrylate, the hydrogenated isoprene multipolymer of star topology or vinylbenzene diene copolymer; Wherein the ethylene content of ethene-propylene copolymer is not higher than 50%, and number-average molecular weight is between 60,000-9 ten thousand or 10-17 ten thousand, shear stable index 15-35, polymethacrylate are amount of carbon atom C8-C20 polymethacrylate enriched material, shear stable index SSI is the shear stable index of the hydrogenated isoprene multipolymer of 13-20 star topology is 15-20, and the styrene content of vinylbenzene diene copolymer is not higher than 45%.When viscosity index improver add-on is lower, base oil in oil product need be increased, base oil ratio crosses high low-temperature startup performance and the low-temperature fluidity having influence on multi-stage engine oil of meeting, when the add-on of viscosity index improver is more than 10%, can because of the excessive detergency having influence on engine of the viscosity index improver of macromolecule ratio in oil product, cause high temperature deposition thing too much, simultaneously by the viscosity of the excessive increase of viscosity index improver, the viscosity of mixed base oil itself can be reduced, make the viscosity of oil product after engine is sheared too low, cause oilness to be deteriorated.Pour point depressant 0.06-1.2 part, this pour point depressant is one or more in alkylnaphthalene, poly-α-alkene, polymethacrylate, fumarate or toluylic acid; Kilfoam 0.001-0.02 part, this kilfoam gather in methyl-silicone oil, dimethyl silicone oil, acrylate and ether copolymer or silicon type and non-silicon type composite anti-foam agent one or more, the molecular weight of poly-methyl-silicone oil is 8-10 ten thousand; The molecular weight of described dimethyl silicone oil is 5-10 ten thousand.
Above-mentioned two kinds of base oils and additive are the currently available products that market can directly be bought.
