Description
Technical field
The present invention relates to a kind of engine oil, particularly relate to a kind of can the engine oil of natural degradation, belong to technical field of lubricating oil.
Background technology
Engine is the heart of automobile, and it includes manyly does the parts run up, as piston, bent axle, camshaft, inlet and exhaust valve etc.These parts are quite severe in the running with the phase mutual friction of other parts.If do not have the lubrication of lubricating oil, the moving parts of so these phase mutual friction will very quick-wearing, causes engine not run well, even damages.
The basic role of engine oil is between metal friction part, form the reliable oil film of one deck, cut off the metal to-metal contact between metal friction part, in addition, engine oil also have other some effect, include: lubrication, cooling effect, rust protection effect, sealing function, cleaning action.Engine oil generally can be divided into: plant machine oil, mineral machine oil, synthetic motor oil.
Because the usage quantity of engine oil is very large, after discarded, it is not easy degraded, and it is high that other recovery and treatment method all exists cost, the shortcoming and defect that process is inconvenient.
Summary of the invention
The object of the invention is: deduct a percentage a kind of can the engine oil of natural degradation, the technical scheme of employing is:
A preparation method for degradable engine oil, comprises the steps:
1st step, by weight, get vegetables oil 30 ~ 50 parts, sodium bicarbonate 1 ~ 3 part, after mixing, be heated to 50 ~ 60 DEG C, backflow insulation 1 ~ 3 hour, lets cool, gets supernatant liquor;
2nd step, supernatant liquor to be distilled, collect the cut of 170 ~ 190 DEG C of sections;
3rd step, add in cut sulfuration Triphenyl phosphate (TPP) 0.5 ~ 1 part, succimide 1 ~ 2 part, isopropylcarbinol 3 ~ 5 parts, oleic acid trialkylphosphate 0.5 ~ 0.7 part,
twoglycol butyl ether 0.3 ~ 1 part, 0.5 ~ 1 part, 2-aminoethyl 17 thiazolinyl imidazoles dodecenylsuccinic acid sodium, antioxidant 0.5 ~ 0.8 part, 1 ~ 1.5 part, softening agent, calcium mahogany sulfonate 0.5 ~ 1 part, be warming up to 40 ~ 60 DEG C, backflow insulation 1 ~ 3 hour, lets cool.
As preferably, described vegetables oil is flower seed oil, Oleum Gossypii semen or sesame oil.
As preferably, described antioxidant is BHA or tertiarybutylhydroquinone.
As preferably, described softening agent is the one in Octyl adipate or dioctyl sebacate.
Be the acidic substance removed wherein by the object that vegetables oil carries out alkalizing, distill, and extract good fraction section, can lubricant effect be improved.
beneficial effect
Engine oil provided by the invention, high lubricating effect, can biological degradation, avoids lubricating oil and abandons the environmental pollution caused.
