Description
Technical field
The present invention relates to a kind of novel FC two stroke engine oil compsn, 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
Characteristics such as it is in light weight, cheap, simple to operate that two-stroke engine has are widely used in fields such as mower, chain saw, small generator, Small-sized Marine outboard generator, snowmobile, float amount 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 mover relies on negative pressure that propellant combination is sucked engine cylinder; The lubricating oil and the fuel oil that suck burn simultaneously, and thermal load is high, very easily stagnate and attach the 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 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 workplace of clutch coupling simultaneously.Because the work characteristics of clutch coupling is opposite fully with the characteristics of engine-driven gearing, the workplace of clutch coupling is instantaneous contact and separate.When the instantaneous contact of workplace of clutch coupling, workplace must be held tightly simultaneously, and with the adjustment transmission rig, in case adjustment finishes, workplace again must sharp separation.If the extreme pressure anti-wear additives that adds has formed the wearing-resistant layer of firm, stable on workplace; The two-stroke engine that will cause rapid movement work is when needs adjustment working order; Skidding appears in clutch coupling, and it is out of control to produce two-stroke engine, 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 interior driving part of two-stroke engine cylinder and piston-ring; Solve the generation of slipping of clutch phenomenon again, solved the problems referred to above that exist in the prior art.
Another object of the present invention provides a kind of preparation method of the above-mentioned FC of being used for two-stroke gasoline engine machine oil extreme pressure antiwear composite.
FC two-stroke gasoline engine engine oil base oil of the present invention, by mass parts, said composition is made up of following component:

In the invention described above FC two-stroke gasoline engine engine oil base oil, the mass parts of preferred chromic oxide is 2 parts.
In the invention described above FC two-stroke gasoline engine engine oil base oil, the mass parts of preferred polyoxyethylene glycol is 1.5 parts.
Another object of the present invention provides a kind of preparation method of novel FC level two-stroke gasoline engine engine oil base oil, comprises the steps:
1. be that to mix the back at 19: 1 soluble in water with rhombspar and Starso by mass ratio, it is joined the porcelain grinding in ball grinder, temperature is controlled at 60-80 ℃, and milling time is no less than 12 hours, until forming the slurry of solids particle diameter less than 3 microns;
2. the slurry after will grinding carries out flotation with zero(ppm) water, dehydrates 2h at 105 ℃, floatingly selects granularity less than 3 microns rhombspar powder;
3. by mass parts, take by weighing the 2. rhombspar 10～15 of gained of step, two-stroke gasoline engine machine oil 60～80, chromic oxide 1～3 is mixed to join in the closed unit with polyoxyethylene glycol 1～2, 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 into 18000rmp and stirred 10 minutes down, and rotating speed is adjusted into 28000rmp and stirred 10 minutes down, forms the emulsion of abundant dispersion suspension;
4. fine dispersion 30min in the ultra-sonic generator of 1KW.
The above-mentioned FC of being used for two stroke engine oil preparation of compositions method 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 compsn of the invention described above is used in motorcycle, chain saw, mower, sled and the 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 and two-stroke engine lubricating oil are to mix use at 1: 100 by mass ratio.
The beneficial effect that the present invention produces:
Novel FC two stroke engine oil compsn of the present invention can have the wearing layer that produces extreme hardness on the continuous high speed contact workplace at driving part, main bearing babbitting jig part, piston-ring etc., and this rigidity layer microhardness can reach more than the HV1000.The requirement of FC two-stroke engine extreme pressure property and abrasion resistance can be effectively solved, the wear-resisting requirement of interior driving part of two-stroke engine cylinder and piston-ring can be satisfied, the generation that has solved the slipping of clutch phenomenon again.
