Compared with standard formula engine oil which passes API authentication, the engine oil prepared by the invention not only reaches the quality standard of API, but also has higher shear stability and lower friction coefficient, and has the function of reducing the consumption of engine oil and fuel oil of an automobile engine, and the oil change mileage is prolonged.
Description
Technical Field
The invention relates to the technical field of lubricating oil, in particular to automobile engine lubricating oil with the function of simultaneously reducing engine oil consumption and fuel consumption and a preparation method thereof.
Background
The lubricating oil for automobile engine, engine oil for short, is used to lubricate the friction pair between engine cylinder and piston ring, intake and exhaust valve, worm supercharger, crankshaft, camshaft bearing, etc. and has the functions of antiwear, sealing, cooling, antirust, cleaning, damping, etc. The engine oil has the most important index of 100 ℃ kinematic viscosity, KV100 for short, which is the main index for measuring the internal friction resistance of oil products, and the high-temperature viscosity grade of the oil products is distinguished according to KV 100. The viscosity of the oil product directly determines the antiwear lubricating effect, the sealing effect and the internal energy consumption of the engine. The higher the viscosity of the oil product is, the stronger the bearing capacity is, the better the wear-resistant protection is, the better the sealing effect is, but the higher the internal energy consumption of the engine is; the lower the viscosity of the oil, the smaller the bearing capacity, the poorer the antiwear effect and the poorer the sealing effect, but the lower the internal energy consumption of the engine. The sealing effect of engine oil is related to engine oil consumption, and the internal energy consumption of the engine directly influences the fuel consumption of an automobile. The better the sealing performance, the lower the engine oil consumption; the poorer the sealing performance, the greater the oil consumption. The higher the internal energy consumption of the engine is, the higher the fuel consumption of the automobile is; the lower the internal energy consumption of the engine, the lower the fuel consumption of the automobile. Thus, the viscosity of the engine oil actually directly affects the consumption of the motor oil and the consumption of the fuel. These are a pair of spears, increasing the viscosity of the engine oil reduces oil consumption, but increases fuel consumption.
With the development of automobile manufacturing technology and the upgrading of environmental regulations of automobile emission, the working conditions of the engine are more and more demanding, and engine oil matched with the engine oil is needed. The standard of automobile engine oil in China is made according to the API standard, and the API adopts a formula certification permission system. The formula passing the API certification is mainly developed by international famous lubricating oil additive companies, and the lubricating oil manufacturers produce the formula according to the standard passing the API certification so as to meet the standard requirement of the API. However, this raises another problem, as the approved conditions for the formulation provided by the additive company are standard conditions-new vehicle and specific operating conditions, and the viscosity profile for the engine oil design is small. The lubricating oil for various automobile engines is difficult to solve by using a low-viscosity formula of an additive company in the same viscosity grade due to different running mileage, different vehicle materials, different working conditions and different engine manufacturing precision of actually running vehicles and different abrasion conditions and gaps of various friction pairs of the engines. As a result, most vehicles using this standard formulation suffer from low oil pressure, high oil consumption (best in european vehicles such as audi, gallo, bmw, and passat), high engine noise, short oil life, frequent engine failure, and the like. In view of this, some lubricating oil manufacturers solve these problems by increasing the viscosity of the engine oil based on the use of standard formulations, but with the new problems of excessive engine fuel consumption, reduced vehicle power, unsuitability for new vehicles and vehicles with better vehicle conditions.
In the prior art, some additives for lubricating oil are adopted, the friction coefficient of the lubricating oil is reduced by adding nanoparticles, but the nanoparticles are not compatible with the lubricating oil, the ash content is higher than the engine oil standard due to too large additive amount, and the cost is higher and is not paid. Therefore, the existing automobile engine oil has the problems of high engine oil consumption and high fuel consumption in use, and no lubricating oil formula in the prior art can solve the problems of reducing the engine oil consumption and the engine fuel consumption at the same time.
Disclosure of Invention
In view of the above, the invention provides an automobile engine lubricating oil with a function of simultaneously reducing engine oil consumption and fuel oil consumption and a preparation method thereof, which can simultaneously solve the problems of high engine oil consumption and high engine fuel oil consumption on the premise of meeting the lubricating requirements of an automobile engine, and prolong the service lives of the engine oil and the engine, thereby being more practical.
In order to achieve the first object, the invention provides an automobile engine lubricating oil with the function of reducing engine oil consumption and fuel consumption simultaneously, which comprises the following technical scheme:
the automobile engine lubricating oil with the function of simultaneously reducing engine oil consumption and fuel oil consumption is characterized by comprising the following raw materials in percentage by mass: the lubricant comprises a compound additive, 0.3-0.5% of pour point depressant required by an authentication formula, an adhesive agent required by the authentication formula with the dosage not more than 9%, 60-75% of base oil required by the authentication formula, 5-10% of alkyl naphthalene synthetic base oil and 0.3-1.0% of organic polymer friction modifier, wherein the compound additive is a standard compound additive which passes the API formula authentication, the dosage is the addition amount required by the authentication formula, the rest raw materials are selected within the percentage range respectively according to the dosage of the compound additive, the physical and chemical indexes of the blended finished oil meet the requirements of the corresponding API grade, and the kinematic viscosity of the finished oil at 100 ℃ reaches the medium upper value requirement in the viscosity grade.
In the raw materials in the automobile engine lubricating oil, the compound additive should be selected from standard compound additives which pass the certification of an API formula, such as HiTEC 9490 or HiTEC 11100 of the gasoline engine oil compound additive (gasoline engine oil) YaFuton company, or P6660 of the Union of Runko company, and the dosage is 10.1 wt.% to 13.5 wt.%: or the diesel engine oil composite additive (diesel engine oil) D3494 of RunYing Union and HiTEC 1255 of Yafudun, and the dosage is 13.2 wt% to 16.2 wt%. Correspondingly, the pour point depressant, the finger-sticking agent and the base oil should adopt the models required by the certification formula, for example, the pour point depressant is polymethacrylate or a vinyl acetate/fumarate copolymer; the adhesive is a dispersed olefin copolymer or hydrogenated styrene isoprene; the base oil is two or three of II-type hydrocracking paraffin base oil, III-type secondary hydrocracking isodewaxing paraffin base oil or IV-type synthetic base oil of alpha olefin.
The standard composite additive, pour point depressant, finger sticking agent and base oil which pass the API formula certification are selected to meet the minimum requirement of the quality standard of the engine oil.
Furthermore, the physical and chemical indexes of the prepared finished oil meet the requirements of the corresponding grade of API, wherein the kinematic viscosity of the finished oil at 100 ℃ reaches the requirement of a medium upper value in the viscosity grade, so that the sealing effect of the oil product in high-temperature operation is ensured, and the oil consumption is reduced.
Furthermore, two key materials of the alkyl naphthalene synthetic base oil and the organic polymer friction modifier are added in a standard formula which passes API formula authentication, and the synergistic effect of the two key materials can change the friction state, improve the boundary lubrication condition, reduce the part wear, obviously reduce the friction coefficient and the friction resistance of the oil product, and improve the thermal oxidation stability and the shear stability of the oil product, thereby reducing the running resistance of each lubrication part of an engine and reducing the fuel consumption of an automobile under the high-viscosity condition. The alkyl naphthalene synthetic base oil is high-viscosity low-pour-point alkyl naphthalene synthetic base oil, such as AN23, AN30 and the like. The organic polymer friction modifier is an organic molybdenum friction reducer or a high molecular type organic friction modifier, such as Molyvan855 from Vanbatt, Perfad 3057 from Dada, and the like.
The automobile engine lubricating oil with the function of simultaneously reducing the consumption of engine oil and fuel oil can be prepared by the following method: adding base oil and alkyl naphthalene synthetic base oil into a blending kettle, stirring for 5-10 minutes, adding a finger-sticking agent, stirring for 5-10 minutes, adding a composite additive and an organic friction modifier, stirring for 5-10 minutes, adding a pour point depressant, stirring for 30-50 minutes, and keeping the temperature of oil in the blending kettle at 55-65 ℃.
The action and the use requirements of the raw materials in the invention are as follows:
the pour point depressant has the function of adjusting the low-temperature performance of the oil product.
The finger-sticking agent has the functions of improving the viscosity-temperature performance of oil products and increasing the viscosity of the oil products, the viscosity of the oil products increased by the finger-sticking agent has shear loss, oil sludge can be increased, the service life of the oil products is influenced, and the finger-sticking agent is used as little as possible and is not more than 9%.
The base oil is a combination of two or three of high-viscosity, medium-viscosity and low-viscosity base oils, is used for adjusting the high-temperature and low-temperature performances of an oil product, is not limited by an authenticated formula, but the physical and chemical indexes of the blended finished oil product must meet the requirements of API (application program interface) related grades, and the kinematic viscosity at 100 ℃ reaches the requirements of medium upper values in viscosity grades.
The specification, type and dosage of the alkyl naphthalene synthetic base oil are determined according to the viscosity grade of the finished oil, high-viscosity oil and large dosage are selected as far as possible, and the minimum dosage is not less than 5%. The alkyl naphthalene synthetic base oil should have excellent thermal oxidation stability, shear stability, hydrolytic stability, additive solubility, lower evaporation loss and good compatibility with sealing materials. The material is used for improving the shear stability of the oil product in the using process, so that the high-temperature viscosity of the oil product is kept stable, the high-temperature lubricating property and the sealing property of the oil product are improved, and the consumption of engine oil is reduced. Meanwhile, the material can also increase the solubility of the composite additive and other materials in the formula, play a role in synergism and prolong the service life of the engine oil. The alkyl naphthalene synthetic base oil has the defect of slightly poor low-temperature fluidity and needs to be adjusted by the base oil.
The organic polymer friction modifier is an organic molybdenum friction reducer or a high molecular type organic friction modifier, such as Perfad 3057 produced by CRODA (Dada).
