Description
Technical field
The present invention relates to a kind of novel FC two stroke engine oil composition, particularly a kind of motorcycle, chain saw, mower, sled and WIND COOLING TWO STROKE vehicle or facility that are suitable for lubricated various discharge capacities.Belong to the material technology field.
Background technology
The characteristics such as it is lightweight, cheap, simple to operate that two-stroke engine has are widely used in the fields such as mower, chain saw, small generator, Small-sized Marine outboard generator, snowmobile, small-displacement motorcycle.
The transmission mechanism of two-stroke engine and clutch coupling are in same system.Machine oil and fuel oil add by a certain percentage, form hybrid burning.Because this type of engine relies on negative pressure, propellant combination is sucked engine cylinder, the lubricating oil and the fuel oil that suck burn simultaneously, thermal load is high, very easily stagnant attached generation settling, 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 add extreme pressure anti-wear additives in lubricating oil.Although 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 simultaneously same system has been produced bad effect.The extreme pressure anti-wear additives that adds not only works in transmission mechanism, also affects simultaneously the performance index of the working face of clutch coupling.Because the work characteristics of clutch coupling is fully opposite 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, and adjusting transmission rig, in case adjust completely, working face again must sharp separation.If the extreme pressure anti-wear additives that adds has formed the wearing-resistant layer of firm stable on working face, to cause the two-stroke engine of rapid movement work when needs are adjusted working order, skidding appears in clutch coupling, produces two-stroke engine out of control, causes the generation of Peril Incident.
Summary of the invention
The object of the present invention is to provide a kind of FC two-stroke gasoline engine machine oil extreme pressure antiwear composite.This extreme pressure antiwear composite has effectively solved the requirement of two-stroke engine extreme pressure property and abrasion resistance, can satisfy the wear-resisting requirement of the interior driving part of two-stroke engine cylinder and piston ring, solve again the generation of slipping of clutch phenomenon, solved the above-mentioned problems in the prior art.

2. the slurry after grinding carries out flotation with distilled water, dehydrates 2h at 105 ℃, floatingly selects granularity less than the rhombspar powder of 3 microns;
3. by mass parts, take the 2. rhombspar 10～15 of gained of step, two-stroke gasoline engine machine oil 60～80, chromic oxide 1～3 and polyoxyethylene glycol 1～2 are mixed to join in closed unit, and vacuum tightness is reached-0.08MPa; Be warming up to 90 ℃, dispersion treatment is 10 minutes under 12000r/min, and adjustment of rotational speed is to stir 10 minutes under 18000rmp, and adjustment of rotational speed is to stir 10 minutes under 28000rmp, forms the emulsion of abundant dispersion suspension;
4. fine dispersion 30min in the ultra-sonic generator of 1KW.
Above-mentioned preparation method for FC two stroke 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 novel FC two stroke engine oil composition of the invention described above is used in motorcycle, chain saw, mower, sled and WIND COOLING TWO STROKE vehicle or the facility of lubricated various discharge capacities.
FC two-stroke gasoline engine engine oil base oil in use, FC two-stroke gasoline engine engine oil base oil mixes use for 1:100 in mass ratio with two-stroke engine lubricating oil.
The beneficial effect that the present invention produces:
Novel FC two stroke engine oil composition of the present invention can have the wearing layer that produces extreme hardness on continuous high speed contact working face at driving part, main bearing babbitting jig part, piston ring etc., more than this rigidity layer microhardness can reach HV1000.The requirement of FC two-stroke engine extreme pressure property and abrasion resistance can be effectively solved, the wear-resisting requirement of the interior driving part of two-stroke engine cylinder and piston ring can be satisfied, the generation that has solved again the slipping of clutch phenomenon.
