Description

Composition oil of gasoline engine and its manufacturing method

Technical field

The present invention relates to a kind of composition oil of gasoline engine.Specifically, the present invention relates to one kind can satisfy SL/GF-3, The composition oil of gasoline engine of SM/GF-4 and SN/GF-5 and the above specification gasoline engine oil product requirement.

Background technique

The high-power and miniaturization of petrol engine is so that the reduction of engine environment air-flow, increases to engine lubricating oil The requirement of oxidation resistance and piston deposit rejection ability.With the increasingly harshness of emission regulation, engine emission is wanted It asks and is also increasingly stringenter, so that higher requirements are also raised to the performance of engine lubricating oil.Petrol engine lubricating oil The requirement for the performances such as it is anti-oxidant to oil product to have updated also constantly improve, piston is peace and quiet, greasy filth disperses, is wear-resistant, it is high at present The product specification of shelves petrol engine lubricating oil has been upgraded to International Lubricant standardization and certification committee (ILSAC) and beauty SM/GF-4, SN/GF-5 rank that institute of Petroleum, state (API) formulates.

Petrol engine oil ageing stability is an extremely important Con trolling index.Lubricating oil is in use process In influenced by the factors such as operation temperature, metal catalytic effect, combustion product and gas blowby, gradually lose antioxidant activity, Yi Fa Raw oxidation deterioration, causes detergency, dispersibility and wear resistence of oil product etc. quickly to be destroyed, and viscosity increases, formation paint film, Deposit causes damages to engine components.

The engine evaluation test of the high-grade anti-oxidant viscosity build of petrol engine lubricating oil is small from the 64 of program III E When, 80 hours for developing to program III F, by 100 hours of current procedure III G, and viscosity build required to never exceed 375% is reduced to 275%, 150%, greatly improves to the requirement for inhibiting viscosity build.Simulate piston high temperature deposition object TEOST-MHT test requirements document is no more than 45mg from SL's, develops to the 35mg of SM, SN specification, engine sludge scoring it is also proposed that Higher requirement, i.e., generate less greasy filth under harsher operating condition.These variations are all to antioxygenic property and detergency More stringent requirements are proposed for energy.

US 5304314 discloses a kind of phenolic compounds for being suitable as sulfur-bearing and arylamine that antioxidant uses.US 2006/ 0189824A1 discloses a kind of shielding phenolic compounds containing secondary aromatic amine for being suitable as antioxidant and using.But these are existing The compound of technology is in gasoline engine oil in use, the antioxygenic property of oil product, detergent-dispersant performance energy and abrasion resistance are still deposited In room for improvement.In addition, other than the adverse effect of deposit, the corrosion of engine also can serious curtailment engine longevity Life, and the corrosion of some key positions largely also influences the performance of operating condition of engine.The prior art is to rust-preventing characteristic The concern of energy is also far from enough.

Therefore, a kind of composition oil of gasoline engine is still required in the prior art, is not only able to meet current more high standard production The product requirement increasingly harsh to antioxygenic property, and also show excellent detergent-dispersant performance energy, abrasion resistance and rust-preventing characteristic Energy.
