According to the four-stroke gasoline engine oil composition of the SG motorcycle, the requirements of the extreme pressure performance and the abrasive resistance of a four-stroke gasoline engine of the SG motorcycle are solved, the wear-resistant requirements of the transmission part and the piston in a cylinder of the four-stroke engine are satisfied, and a slipping phenomenon of a clutch is solved.
Description
Technical field
The present invention relates to a kind of SG motorcycle four-stroke composition oil of gasoline engine its preparation method and application, belong to the material technology field.
Background technology
In general, all functions position and the parts of motorcycle engine design for barrel type crankcase, and engine oil is all had an effect to all parts in the crankcase.Oil product mostly is used for the lubricated of engine, clutch coupling, transmission mechanism simultaneously, so to machine oil performance requriements height.The engine of automobile and motorcycle being compared, can find that the peak power output of motorcycle can reach 45～140kW/L, is 1.3～1.8 times of automobile.And turn up 6000～15000r/min during peak power output is 1.3～2 of automobile.Most of motorcycles all adopt air-cooled, cause the working temperature of engine can reach 160 ℃ sometimes.
Because all functions position and the parts of motorcycle engine design for barrel type crankcase, machine oil and fuel oil add crankcase by a certain percentage, form hybrid burning.Because this type of engine relies on negative pressure that propellant combination is sucked engine cylinder, the lubricating oil and the fuel oil that suck burn simultaneously, the thermal load height, attached generation settling very easily stagnates, this stagnant adventitious deposit thing in piston and cylinder wall accumulation will cause the piston ring packing function to reduce, get rusty, connecting rod and main bearing lubrication were lost efficacy, and made the compression ratio loss of engine cylinder, and outputting power descends.
For fear of the generation of above-mentioned situation, usually in lubricating oil, add extreme pressure anti-wear additives.Though extreme pressure anti-wear additives can make the performance of engine cylinder and piston ring make moderate progress and improve, and the clutch coupling that is in same system has simultaneously been produced bad effect.The extreme pressure anti-wear additives that adds not only works in transmission mechanism, also influences the performance index of the working face of clutch coupling simultaneously.Because the work characteristics of clutch coupling is opposite fully with the characteristics of engine-driven gearing, the working face of clutch coupling is instantaneous contact and separate.When the instantaneous contact of working face of clutch coupling, working face must be held tightly simultaneously, to adjust transmission rig, finishes in case adjust, and working face again must sharp separation.If the extreme pressure anti-wear additives that adds has formed the wearing-resistant layer of firm stable at working face, will cause the engine of rapid movement work when needs are adjusted working order, skidding appears in clutch coupling, produces engine runaway, causes the generation of Peril Incident.
Summary of the invention
The object of the present invention is to provide a kind of SG motorcycle four-stroke composition oil of gasoline engine and its preparation method and application.This extreme pressure antiwear composite has effectively solved the requirement of SG motorcycle four-stroke engine extreme pressure property and abrasion resistance, can satisfy the wear-resisting requirement of the interior driving part of Otto cycle engine cylinder and piston ring, the generation that has solved the slipping of clutch phenomenon again.
The technical scheme that the present invention deals with problems is: a kind of SG motorcycle four-stroke composition oil of gasoline engine, and said composition is made up of following component by mass parts:

The mass parts of single month silicic acid fat of the above-mentioned preferred anhydrous sorbitol of SG motorcycle four-stroke composition oil of gasoline engine is 1.5.
Another object of the present invention provides the method for preparing SG motorcycle four-stroke composition oil of gasoline engine, and this preparation method comprises the steps:
1. be that to mix the back at 4: 1 soluble in water with illite and Starso by mass ratio, it is joined the porcelain grinding in ball grinder, temperature control at 80～95 ℃, and milling time is no less than 12 hours, until the slurry of formation solids particle diameter less than 2 microns;
2. the slurry after will grinding carries out flotation with distilled water as flotation medium, dehydrates 2 hours at 135 ℃, floatingly selects granularity less than 2 microns illite powder;
3. take by weighing the 2. illite 10～15 of gained of step by mass parts, SG motorcycle four-stroke gasoline engine oil 60～80, single month silicic acid fat 1～2 of calcium oxide 1～3 and anhydrous sorbitol is mixed to join in the closed unit, and vacuum tightness is reached-0.08MPa; Be warming up to 90 ℃, dispersion treatment is 10 minutes under 12000r/min, and rotating speed is adjusted under the 18000rmp and stirred 10 minutes, and rotating speed is adjusted under the 28000rmp and stirred 10 minutes, forms the emulsion of abundant dispersion suspension;
4. fine dispersion 30min in the ultra-sonic generator of 1KW.
Another purpose of the present invention provides the application of above-mentioned SG composition oil of gasoline engine in Otto cycle engine lubricating oil.A kind of Otto cycle engine lubricating oil comprises described SG motorcycle four-stroke composition oil of gasoline engine, and the content of its composition accounts for 1.5% of quality of lubrication oil.
Above-mentioned preparation method for SG motorcycle four-stroke gasoline engine oil engine oil composition also should comprise the finishing sequence to lubricating oil, and those skilled in the art can carry out can to finished product as required.
The New type of S G motorcycle four-stroke composition oil of gasoline engine of the invention described above is suitable for four-stroke engine for motor cycle and the wheel box of lubricated import or homemade air cooling, water-cooled.
The beneficial effect that the present invention produces:
SG motorcycle four-stroke composition oil of gasoline engine disclosed in this invention can have continuous high speed contact working face to produce the wearing layer of extreme hardness at driving part, main bearing babbitting jig part, piston ring etc., and this rigidity layer microhardness can reach more than the HV1100.The requirement of SG motorcycle four-stroke engine extreme pressure property and abrasion resistance can be effectively solved, the wear-resisting requirement of the interior driving part of Otto cycle engine cylinder and piston ring can be satisfied, the generation that has solved the slipping of clutch phenomenon again.
