Abstract

The invention discloses a diethylene glycol diethyl ether fuel engine oil composition which is prepared from castor oil-based dioctyl sebacate and II type base oil (which are used as base oil) in combination of a plurality of compound additives. The diethylene glycol diethyl ether fuel engine oil composition comprises an oil-based agent, an oxidization-corrosion inhibitor, an antifoaming agent, a viscosity index improver, a metal deactivator, a clearing agent, a dispersing agent, an antioxidant, an antirust agent and a friction improver. The engine oil composition has excellent cleaning and dispersibility properties, viscosity-temperature characteristic, base value retentivity, and is capable of reducing the generation of piston ring precipitates and keeping an engine clean, as well as inhibiting the generation of black oil sludge; the diethylene glycol diethyl ether fuel engine oil composition has excellent high-temperature oxidization stability, soot solubilizing capability, and anti-wear property; a sealing material can be effectively protected through the rubber compatibility of the diethylene glycol diethyl ether fuel engine oil composition so as to prevent leakage; the diethylene glycol diethyl ether fuel engine oil composition is anti-shearing and capable of effectively controlling the viscosity increase of oil products, good in low-temperature starting performance, capable of reducing the generation of accumulated carbon and paint films of the engine under high-temperature condition, does not corrode or rust moving components, and therefore prolongs the service life and oil change period of the engine.

The mass percent summation of each component is 100%.

Base oil is that castor-oil plant base dioctyl sebacate and 50%～60% the II class base oil of mass ratio 50%～40% is compound.

Purification agent is that middle base number calcium alkylbenzenesulfonate, 25%～30% highly basic calcium naphthenate and 50%～40% the Overbased magnesium sulphonates of mass ratio 25%～30% is compound, and the mass percent summation of above-mentioned three components is 100%; Dispersion agent is that mono alkenyl succimide and 60%～50% the boronation polyisobutylene-bis-succinimide of mass ratio 40%～50% is compound.

Antioxidant preservative is that dialkyldithiocarbamacompositions tungsten and the two octyl group basic zinc salt of 50%～40% sulphur phosphorus of mass ratio 50%～60% are compound; Oxidation inhibitor is 4 of mass ratio 40%～50%, and 4-methylene-bis (2,6 ditertiary butyl p cresol) is compound with 60%～50% Phenyl beta naphthylamine.

Oiliness improver is sulfurized olefin cotton oil.

Metal passivator is that 124 Triazole derivative and 60%～50% the thiadiazoles derivative of mass ratio 40%～50% is compound.

Friction improver is 124 Triazole fatty amine salt.

Rust-preventive agent is that zinc naphthenate and 60%～50% the benzotriazole of mass ratio 40%～50% is compound.

Kilfoam is dimethyl silicone oil.

Viscosity index improver is polymethacrylate.

Remarkable advantage of the present invention has: have good detergent-dispersant performance, sticky-temperature characteristics, base number retentivity, reduce piston ring settling and generate and keep engine washing, can suppress the generation of black greasy filth; Good high-temperature oxidation stability, solubilising soot ability, wear-resistant; rubber compatibility is effectively protected sealing material; Leakage prevention; anti-shearing and effective control oil viscosity increases; cold cranking capacity is good; can reduce the generation of engine carbon deposit, paint film under hot conditions, corrosion-free and corrosion, increasing service life of engine and oil draining period to moving parts.
