Problems solved by technology

[0002] According to the survey, vehicle oil leakage is a common phenomenon in the car market. Among the existing 1.2 million taxis in the country, 70% of the vehicles have oil leakage to varying degrees; Among them, the proportion of oil leakage has reached 15%; that is to say, there are more than 4.7 million car users in the country suffering from oil leakage problems; the maintenance method of replacing oil seals is generally used, which is not only expensive, but also difficult to cure
On the issue of anti-leakage, the existing vehicle maintenance methods in the market cannot be convenient and affordable, and efficiently and thoroughly solve the problem of oil leakage
There is no single oil that can solve the problem of oil leakage in vehicles

Embodiment 1

[0046] A full-component lubricating oil composition was prepared, named "Guanxiubao" 10W-40, and the existing Longpan lubricating oil Jingwei SJ 15W-40 was used as a comparison.

[0047] The preparation method is as follows: put the base oil (hydrogenated base oil, high-pressure hydrogenated bright stock, alkyl naphthalene) into the blending kettle in proportion, raise the temperature to 75°C, and then add the viscosity index improver (SV-261) and Pour point depressant (1-248), stir for 30 minutes; cool down to 65°C, add detergent and dispersant (boronated succinimide ashless dispersant, sulfurized alkylphenol calcium, synthetic calcium sulfonate, synthetic magnesium sulfonate ), anti-oxidation and anti-wear agent (nitrogen-containing molybdenum thiophosphate, zinc dialkyldithiophosphate, amine antioxidant, phenolic antioxidant), add antifoaming agent (T901) after stirring for 30 minutes; The product was produced after stirring for 15 minutes.

[0048] Its data are shown in T...

Embodiment 2

[0053] Prepare a full-component lubricating oil composition, named "Guanxiubao" 10W-40, the preparation method is the same as in Example 1, and the existing Longpan lubricating oil Jingwei SJ 15W-40 is used as a comparison, and its data are shown in Table 2:

Abstract

The invention relates to a composite of lubricant and a preparation method thereof, in particular to a composite of engine lubricant and a preparation method thereof, which belong to the lubricant technical field. Alkyl naphthalene and naphthenic bright stock are added to base oil and at the same time thiophosphoric acid molybdenum additive containing nitrogen, ashless dispersing agent boride, hydrostyrene-isoprene VI improver (Infineum SV 261) and the like are added. Through the mutual coordination of the components, the lubricant composite has obvious compatibility adaptability of a rubber sealing ring, engine oil leakage is avoided, gas blowby is prevented, the dynamic property of the engine is improved, engine oil consumption is reduced, the emission property of the engine is improved and the oil draining period of engine oil and the service life of the engine are prolonged. The invention is particularly applicable to the vehicles which have run more than 100000km or have been overhauled.

Description

technical field [0001] The invention relates to a lubricating oil composition and a preparation method thereof, in particular to an engine lubricating oil composition and a preparation method thereof, belonging to the technical field of lubricating oil. Background technique [0002] According to the survey, vehicle oil leakage is a common phenomenon in the car market. Among the existing 1.2 million taxis in the country, 70% of the vehicles have oil leakage to varying degrees; Among them, the proportion of oil leakage has reached 15%; that is to say, there are more than 4.7 million car users in the country suffering from oil leakage problems; the maintenance method of replacing oil seals is generally used, which is not only expensive, but also difficult to cure. On the problem of anti-leakage, the existing vehicle maintenance methods in the market cannot solve the oil seepage fault efficiently and thoroughly while being convenient and affordable. There is no single motor oil...
