Abstract
The present invention relates to a lubricating oil composition having the functions of oxidation resistance, wear resistance and attrition resistance. The lubricating oil composition is made from the components in weight percentages: 0.1 to 3.5% of dialkyl zinc dithiophosphate, dialkyl copper dithiophosphate, dialkyl magnesium dithiophosphate, dialkyl calcium dithiophosphate and dialkyl barium dithiophosphate, 0.2 to 3.0% of an antioxidant mixture of an amine antioxidant and a phenolic ester antioxidant, 0.05 to 1.5% of a molybdenum salt of dialkyl dithioic organic acid, 0.05 to 1.5% of a monohydric alcohol ester wear-resistant attrition-resistant agent or a polyhydric alcohol ester wear-resistant attrition-resistant agent generated by a monohydric alcohol or a polyhydric alcohol reacting with alkyl, arene or alkylphenol substituted by carboxylic acid, and 0.05 to 1.5% of a zinc salt, a calcium salt, a sodium salt, a barium salt and a magnesium salt of dialkyl dithiocarbamate or dialkyl dithiocarbamic acid, and balance of lubricating oil.
Description
Technical field
The present invention relates to lubricating oil composition, specifically, is a kind of internal combustion (IC) engine oil composition with the effect of antioxygen antiwear and antifriction, particularly high-grade composition oil of gasoline engine.
Background of invention
Car combustion engine is bearing the function influence of Working environment during operation with lubricating oil, and this environment such as high temperature make oil oxidation and promote the oxidation; The impurity such as compounds such as iron that exists in oil product then plays a part catalysed promoted to this oxidation.I. C. engine oil this oxygenizement during use generally is controlled to a certain extent by use oxidation inhibitor, and oxidation inhibitor can prolong the work-ing life of oil product.The general independent use dialkyl zinc dithiophosphate of I. C. engine oil in the past (ZDDP), or with the compound requirement that can satisfy oil product to antioxidant property of a spot of pentanoic type oxidation inhibitor.
Along with the employing of direct fuel injection technology, the oil engine specific power increases, and chamber temperature raises, and I. C. engine oil uses ZDDP or compound a small amount of pentanoic can not satisfy the requirement of oil product to high temperature oxidation resistance separately, the oxidation inhibitor of compound other kinds; Simultaneously, because harsh day by day environmental requirement, the installation of Exhaust Gas Catalytic Converter for Automobiles, for prolonging the work-ing life of catalytic converter, oil specification is limited the gasoline engine oil phosphorus content, SH/GF-1 is for being not more than 0.12%, SJ/GF-2 is not more than 0.10%, and SL/GF-3 is for being not more than 0.10%, and SM/GF-4 tentatively is decided to be and is not more than 0.08%, it is impossible to improve antioxygen by the add-on that strengthens ZDDP, therefore wants compound other oxidation inhibitor to remedy the antioxidant property of oil product.
Owing to control phosphorus content, limited the add-on of the ZDDP with the wear-resistant function of antioxygen.Because the increase of oil engine specific power, engine load improves, and the abrasion resistance of employed lubricating oil is proposed higher requirement, and this also requires to use the anti-wear agent of other kinds to improve the abrasion resistance of oil product.
