Abstract

The invention relates to micro-nano engine oil and a preparation method thereof. The micro-nano engine oil is prepared from, by mass, 40%-70% of PAO, 5%-30% of adipate, 1%-5% of polyol ester, 5%-10% of an engine oil complexing agent, 2%-12% of a viscosity index improver, 0.2%-0.5% of a pour point reducer and 0.1%-4% of a compound micro-nano antiwear agent. The micro-nano antiwear agent is micro-nano metal particles, the micro-nano metal particles are treated through the processes of centrifugal separation, grinding dispersion, centrifugal treatment and the like and finally uniformly suspend in PAO to prepare micro-nano concentrated liquid, the micro-nano concentrated liquid is mixed with engine oil mixed liquid taking the PAO as base oil, uniform dispersion of the nano particles is guaranteed, after mixing is conducted, the finished product can be obtained only by conducting constant-temperature stirring for 1 h, and therefore the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and relates to engine oil, in particular to a micronano engine oil and a preparation method thereof. Background technique [0002] As the blood of the engine, lubricating oil plays a very important role in the operation of the engine. Lubricating oil has the functions of lubricating, cooling, sealing, anti-corrosion, and cleaning in the engine. Improving the lubricating performance of lubricating oil can reduce friction, prevent burn marks and reduce wear, reduce the wear capacity of the machine, and improve the operating efficiency of the machine. As far as the engine is concerned, gasoline engines generally consume 7% of the fuel energy in friction losses, while diesel engines consume about 10% of the fuel energy in friction losses. [0003] CN101921655B discloses a self-repairing environment-friendly diesel engine oil. Its formula consists of: environment-friendly base oil, diesel engine oil co...
