Detailed Description
The technical solution of the present invention will be further described with reference to the following embodiments.
The invention relates to heavy-duty diesel engine oil which comprises the following components: 30-60 wt% of mineral base oil, 10-30 wt% of synthetic ester, 10-20 wt% of extreme pressure antiwear agent and 10-20 wt% of detergent dispersant; the synthetic ester is one or more than two of isooctyl oleate, neopentyl polyol ester, trimethylolpropane oleate, trimellitate and dipentaerythritol ester. Wherein, the heavy-duty diesel engine oil is used for national VI CK-410W-40 heavy-duty diesel engines. The mineral base oil is one or more than two of tertiary hydrogenated base oil 100N, tertiary hydrogenated base oil 150N and tertiary hydrogenated base oil 500N. The extreme pressure antiwear agent is one or more than two of olefin, sulfur extreme pressure antiwear agent, phosphorus extreme pressure antiwear agent and synthetic calcium sulfonate. The detergent dispersant is two or more of alkaline synthetic calcium sulfonate, overbased synthetic heavy alkyl benzene sulfonate, overbased magnesium sulfonate and overbased calcium sulfonate. The mass ratio of the mineral base oil, the synthetic ester, the extreme pressure antiwear agent and the detergent dispersant is 1: 0.3-5: 0.1-0.2: 0.1-0.5. Preferably, the extreme pressure antiwear agent comprises the following components: 0-5 wt% of olefin, 2-10 wt% of sulfur extreme pressure antiwear agent, 0-5 wt% of phosphorus extreme pressure antiwear agent and 5-10 wt% of synthetic calcium sulfonate.
The invention relates to a preparation method of heavy-duty diesel engine oil, which comprises the following steps:
(1) adding synthetic ester into mineral base oil, uniformly stirring, and controlling the temperature to be 60-70 ℃ to obtain a first mixture;
(2) adding a detergent dispersant into the first mixture, and uniformly stirring again to obtain a second mixture;
(3) adding the extreme pressure antiwear agent into the second mixture, uniformly stirring and cooling to 50 ℃; obtaining the heavy-duty diesel engine oil product which consists of 30 to 60 weight percent of mineral base oil, 10 to 30 weight percent of synthetic ester, 10 to 20 weight percent of extreme pressure antiwear additive and 10 to 20 weight percent of detergent dispersant.
Due to the high temperature, the high ash additives of conventional diesel engine oils are highly susceptible to the formation of hard deposits on the surfaces of engine components. The common diesel engine oil can not solve the problems of valve abrasion and untight closing caused by gas dryness, and the automobile exhaust contains a large amount of nitrated compounds to promote the nitration of the common diesel engine oil, generate a large amount of oil sludge, block an oil way or generate harmful substances such as a paint film and the like. The problems of vehicle halt, abnormal sound of an explosion engine, power reduction and the like are caused.
Therefore, a novel heavy-duty diesel engine oil product needs to be developed in a targeted manner, and the product 1 is required to have better oxidation resistance and anti-nitration stability at higher temperature; 2. the lubricating grease has good performances of high temperature resistance, abrasion resistance and scratch resistance, and has protection and better lubricating effect on parts difficult to lubricate; 3. in order to reduce various deposits, avoid oil sludge generation and ensure smooth oil path, the lubricating oil is required to have stronger cleaning and dispersing performance; 4. the natural gas mixed in the engine oil is incompletely combusted, carbon deposit, sediment, metal particles, dust, moisture and other pollutants, and acidic corrosive substances are easily generated in a high-temperature and high-pressure environment, so that the lubricating oil is required to have stronger acid resistance and corrosion resistance.
The heavy-duty diesel engine oil adopts the advanced middle ash additive technology and the unique anti-wear additive formula, the application of the synthetic base oil further enhances the power protection effect of the additive, prolongs the service life of an engine and an oil product, and the unique additive technology provides more excellent piston ring cleanliness; unique antiwear additives help meet the stringent antiwear requirements of most European, American and Japanese engine manufacturers. Tests prove that the heavy-duty diesel engine oil has the beneficial effects of low emission, is beneficial to preventing the exhaust filter from being blocked, can help to control the blockage of the tail gas aftertreatment device or prevent poisoning by an advanced middle ash distributor, helps to maintain the normal work of an exhaust system, and improves the use efficiency of fuel oil; the oil change device has the beneficial effects of saving maintenance cost, prolonging the oil change period, optimizing maintenance arrangement and controlling maintenance cost under the condition that a user does not need to consider the oil change period; excellent abrasion resistance protection and cleaning performance; the requirements of minimum 150000 kilometer oil change of the tin diesel CA6DL3E6, CA6DM2E6 and CA6DM3E6 diesel engines can be met; compared with the existing high-viscosity oil product, the oil-saving agent can effectively save fuel consumption.
