The lubricating oil is characterized by being prepared from basic oil and a lubricating oil additive. The lubricating oil is specifically prepared from the following raw materials in parts by weight: 86-90 parts of basic oil, 1-3 parts of a clean dispersant, 0.5-1.5 parts of a friction modifier, 0.5-0.7 part of an antirust agent, 0.5-1.5 parts of a pour point reducer, 0.1-0.3 part of a viscosity index improver, 0.3-0.5 part of an anti-wear reagent at extreme pressure and 1-3 parts of an internal combustion engine oil complexing agent. The lubricating oil provided by the invention is prepared from the raw materials. The antifriction and antiwear performances of the lubricating oil of the automobile can be improved, and moreover, the oxidation resistance can be further effectively improved, generation of high temperature deposits of the lubricating oil is reduced, temperature rise of oil products is inhibited, overhead of an engine is reduced, and the high-temperature oxidation condition is effectively controlled.
Description
Technical field
The invention belongs to technical field of lubricating oil, be specifically related to a kind of efficient antifriction motor oil.
Background technology
Lubricating oil is used in all kinds mechanically to reduce friction, protection machinery and the liquid lubricant of workpiece, mainly play lubrication, cooling, antirust, clean, seal and the effect such as buffering.But mechanical transmission kind is a lot, also not identical to the requirement of lubricating oil.
And domestic automobile lubricating oil processing technology focuses in the maintenance of motor car engine, focus in the performance of the anti-friction anti-attrition of lubricating oil, quiet dispersion, high-temperature oxidation resistant.But Lubricating Oil Technique development trend reduces friction to greatest extent in the world, lower power loss, thus reduce fuel consumption.According to measuring and calculating, the 30-40% of the world consumption energy consumes in frictional wear, and that is the whole world about has every year and is equivalent to 2,000,000,000 tons of petroleum-based energies and wastes in frictional wear.Engine in the running, if some abrasion positions can not get suitable lubrication, will produce metal to-metal contact.Facts have proved, the heat that metal to-metal contact produces at short notice is enough to make melting of metal, causes the breakage of parts even stuck.Therefore good lubrication must be given to the abrasion position of engine.When after flow of lubricant to abrasion position, will stick on friction surface and form one deck oil film, reduce the resistance between friction parts, and oily film strength and toughness be the keys playing its lubrication.
Summary of the invention
For the shortcoming of above-mentioned prior art, the present invention in order to object be to provide a kind of efficient antifriction motor oil.
Technical scheme of the present invention is: a kind of efficient antifriction motor oil, it is made up of base oil and lubricating oil additive, is specifically made up of the proportioning raw materials of following parts by weight: base oil 86-90 part, detergent-dispersant additive 1-3 part, friction improver 0.5-1.5 part, rust-preventive agent 0.5-0.7 part, pour point depressant 0.5-1.5 part, viscosity index improver 0.1-0.3 part, extreme pressure anti-wear additives 0.3-0.5 part, I. C. engine oil recombiner 1-3 part.
Base oil of the present invention can be paraffin base oil, described detergent-dispersant additive can be succinate, described friction improver can be able to can can be phosphorous acid ester for polyvinyl n-butyl ether, described extreme pressure anti-wear additives for vinyl acetate, described viscosity index improver for dodecenylsuccinic acid, described pour point depressant for sulfide isobutene, described rust-preventive agent.
A kind of preparation method of efficient antifriction motor oil, in a heat-resisting container, add base oil, detergent-dispersant additive, friction improver, rust-preventive agent, pour point depressant, viscosity index improver, extreme pressure anti-wear additives, I. C. engine oil recombiner successively, be heated to 60-70 DEG C while stirring, maintain about 20min, make material even, obtain the liquid of a thickness.
The effect of raw material of the present invention is as follows:
Lubricating oil is generally made up of base oil and additive two portions.Base oil is lubrication main body of oil, and decide the essential property of lubricating oil, additive then can make up and improve the deficiency of base oil aspect of performance, gives the performance that some is new, is the important component part of lubricating oil.
Detergent-dispersant additive: during internal combustion engine, engine oil will bear the severe condition of high temperature, high pressure, and with the oxygen in air and metallic contact, be thus oxidized, condensation, the reaction such as decomposition, form greasy filth, carbon deposit, bituminous matter, colloid and organic acid etc. thus.Fuel combustion is incomplete, and the carbon deposit of generation is deposited on engine part, also makes engine operation worsen.Add the object of detergent-dispersant additive, will by the solubilising of peace and quiet point quiet dose, dispersion, acid neutralization and cleaning function, make to be deposited on greasy filth on mechanical surface and carbon deposit washs, and make their dispersions and be suspended in oil to be removed by strainer, thus make piston and other component keep clean, normally work.
Friction improver: be preferentially adsorbed on metallic surface, forms firmly adsorption film, is reducing friction close under condition of boundary lubrication.
Rust-preventive agent: there is infiltration rust cleaning, loosen lubrication, resist the performances such as burn into protection metal.
Viscosity index improver: effect is along with the rising of temperature makes oil body increase.
Extreme pressure anti-wear additives: formed the solid film with low sheraing intensity by chemical reaction in metallic surface, prevent intermetallic contact.
Beneficial effect: the present invention can improve the anti-wear and wear-resistant performance of motor oil, effectively can also improve antioxidant property simultaneously, reduces lubricating oil high-temp settling and generates, and suppresses oil product temperature to raise, reduces engine overheat, effectively control high temperature oxidation situation.
