Technical field

The present invention relates to petrochemical industries, are related to a kind of wear-resistant gasoline engine machine oil.

Background technique

In recent years, with the fast development of Domestic Automotive Industry, China automobile market Europe system automobile proportion increases year by year Greatly, also more and more to the engine oil demand for meeting ACEA specification.Compared with U.S. system and system, Japan and Korea S automobile, in Europe system automobile Car travel speed is fast, and engine compresses are higher, and engine speed is also high, causes engine heat load and mechanical load Height, engine oil operating temperature is high, and use condition is harsh, and the drain period is long, very high to engine oil performance requirement.Therefore ACEA Specification ratio API specification is more stringent in some aspects.In order to meet harsh emission regulation, the design and control technology of engine It continuously improves, delayed injection and EGR Technology propose requirements at the higher level to the soot dispersibility of lubricating oil.The sedan-chair in Europe Vehicle manufacturer requires lubricating oil that can extend the oil draining period on higher power engine and improves fuel economy, higher thermic load And mechanical load, lubricating oil need to have stronger anti-oxidant and abrasion resistance.

Gasoline engine machine oil on domestic market is generally to be difficult to meet in some cases according to API specification development The engine oil demand of ACEA specification especially has very big gap on anti-oxidant and abrasion resistance, therefore develops a kind of suitable The engine oil for closing ACEA specification becomes one of our urgent problems to be solved.

Summary of the invention

The present invention provides a kind of wear-resistant gasoline engine machine oil for problems existing for existing gasoline engine machine oil, The machine oil main component includes detersive, dispersing agent, antioxidant, antiwear additive, anti-friction composition, extreme pressure agent, viscosity index improver, pour-point depressant, ester Class oil, high viscosity synthetic base oil, synthetic base oil or mineral base oil, many of reagent are all made of bi-component, and existing Technology is compared, and machine oil provided herein may conform to ACEA A3/B4 engine oil index request in performance, and wear-resistant Ability is prominent, provides quiet smoothly driving experience.

For state of the art situation, inventor has been put forward for the first time with molybdenum dithiocarbamate and the poly- carboxylic of alkyl The ratio mixing preparation anti-friction composition of acid ester derivant 5:1, the in addition collocation of HSD type viscosity index improver, metallocene synthetic oil and Esters oil Mode, in the case where cryogenic property meets, surplus maximum composition uses Group III mineral base oil, and Lai Tigao machine oil resists Mill ability, to have the function that noise reduction.

Based on above-mentioned body design thinking, it is as follows to inventor provide specific technical solution:

A kind of wear-resistant gasoline engine machine oil, the wherein mass percent of each component are as follows: detersive 2.9-4.0%, dispersing agent 2.5-3.8%, it antioxidant 0.5-0.8%, antiwear additive 0.5-1.5%, anti-friction composition 0.1-1.0%, extreme pressure agent 0.1-0.8%, glues Refer to agent 4.0-13.5%, pour-point depressant 0.1-0.5%, Esters oil 5.0-12.0%, high viscosity synthetic base oil 3.0-8.0%, close At base oil or Group III mineral base oil surplus；

Wherein, synthetic base oil or Group III mineral base oil can be according to the requirements of engine oil viscosity rank according to existing skill Art random selection；

The anti-friction composition be molybdenum dithiocarbamate (such as Molyvan3000) and alkyl polycarboxylate derivative (such as Vanlube7723) ratio of 5:1 mixes；

Inventor by long-term research with found after experiment, using the anti-friction composition of above-mentioned composition, can with it is viscous with HSD type Refer to agent, the collocation of metallocene synthetic oil and Esters oil, play apparent synergistic effect each other, can play that greatly improve machine oil anti- The effect of mill ability, is obviously improved compared with the prior art；

By weight calculating, the detersive is sulfenyl phenolate (such as T115B) and alkylbenzene sulfonate (such as T106) It is mixed with the ratio of 2:1；

The dispersing agent is polyisobutene imidodicarbonic diamide (Ashless type) (such as T164B) and succinic acid ester type polymeric dispersant (such as LZL 156) is mixed with the ratio of 3:1；

The antioxidant is that shield phenol type (such as T501) and the ratio of alkyl diphenylamine (such as T534) 1:1 mix； The antiwear additive is dithiophosphates (such as Hitec059)；

The extreme pressure agent is dithiocarbamates methyl antimony (such as Vanlube73) and molybdenum dithiophosphate (such as Molyvan L) ratio of 1:1 mixes；

The viscosity index improver is hy drogenated styrene-diene copolymer (such as Lubrizol7441)；

The pour-point depressant is Polymethacrylate type (such as Viscoplex1-158) and alkylnaphthalene type (such as T801) 2:1 Ratio mix；

The Esters oil is polyol ester (such as PE478)；

The high viscosity synthetic base oil is metallocene synthetic oil；

It is the trade name of corresponding product disclosed in above-mentioned bracket, is that can directly buy in the market, inventor Details are not described herein, as long as but inventor it should be noted that other similar products having the same can act on, It is used using the alternative substance as the application；

The selection of said components is for preferably being used cooperatively with anti-friction composition and its dosage etc. being optimized, that This direct interaction can play better effect；Under its wear-resistant coefficient of the machine oil finally obtained is obvious compared with the prior art Drop, indicates that its abrasion-resistance is obviously improved；

Inventor still further provides the preparation method of above-mentioned wear-resistant gasoline engine machine oil, comprises the concrete steps that:

(1) single dose is prepared: first by detersive, dispersing agent, antioxidant, anti-friction composition, extreme pressure agent, pour-point depressant in respective ratio list It solely reconciles, 65 DEG C of constant temperature, continuously stirs 2h；

(2) total reconciliation phase: it is proportionally added into synthetic base oil or Group III base oil, is proportionally added into high viscosity later Synthetic base oil, then it is proportionally added into Esters oil, it is finally proportionally added into remaining ingredient, 60-65 DEG C of constant temperature, continuously stirs 1h.
