preparation example Construction

[0021] A method for preparing lubricating oil, comprising mineral base oil, poly-α-olefin (PAO), neopentyl polyol mixed fatty acid ester, zinc dialkyldithiophosphate, rare earth oxide; specifically comprising the following steps:

[0022] Get the mineral type base oil that is 50-60% by weight and the poly-alpha-olefin (PAO) that is 15-40% by weight, stir at T1 ℃ 1 hour to obtain mixed base oil A;

[0023] 7% by weight of neopentyl polyol mixed fatty acid ester and 1% by weight of borated fatty acid ester are added to the mixed base oil A, at T 2 Stir at t 2 Hour, obtain base oil B;

[0024] In the mixed base oil B, add 2% zinc dialkyldithiophosphate by weight, at T 3 Reaction at ℃ 3 Hour, obtain base oil C;

[0025] Add x% rare earth oxide powder to the base oil C, and react at 50-60°C for t 4 hours to obtain the final product.

[0026] The T 1 , T 2 , T 3 , satisfy the following relationship: 30≤T 2 1 3 ≤80, the unit is ℃. In order to fully disperse the zinc dialk...

Embodiment 1

[0030] Take the mineral type base oil that is 50% by weight and the poly-alpha-olefin (PAO) that is 35% by weight, stir at 50 ℃ for 4 hours to obtain mixed base oil A;

[0031] 7% by weight of neopentyl polyol mixed fatty acid ester and 1% by weight of borated fatty acid ester were added to the mixed base oil A, and stirred at 40°C for 2 hours to obtain base oil B ;

[0032] Adding 2% by weight of zinc dialkyldithiophosphate to the mixed base oil B, and reacting at 70°C for 1 hour to obtain base oil C;

[0033] Add x% oxidized rare earth powder to the base oil C, and react at 50-60° C. for 1 hour to obtain a finished oil.

[0034] The rare earth content x has the following relationship with the coefficient of friction of lubricating oil:

[0035] μ=exp[0.6224(lnx) 2 +3.6502lnx+e]±0.01, 0.01≤x≤0.15

[0036] Wherein, μ is the target friction coefficient of the lubricating oil, and x is the weight percentage of the rare earth content in the lubricating oil. The target fricti...

Embodiment 2

[0040] Get the mineral type base oil that is 50% by weight and the poly-alpha-olefin (PAO) that is 35% by weight, stir at 55 ℃ for 3 hours to obtain mixed base oil A;

[0041] 7% by weight of neopentyl polyol mixed fatty acid ester and 1% by weight of borated fatty acid ester were added to the mixed base oil A, and stirred at 40°C for 2 hours to obtain base oil B ;

[0042] Adding 2% by weight of zinc dialkyldithiophosphate to the mixed base oil B, and reacting at 75° C. for 1 hour to obtain base oil C;

[0043] Add x% oxidized rare earth powder to the base oil C, and react at 50-60° C. for 2 hours to obtain a finished oil.

Abstract

The invention provides a lubricating oil and a preparation method thereof. The preparation method concretely comprises the following steps: taking 50-60wt% of mineral base oil and 15-40wt% of poly-alpha-olefin (PAO), stirring at T1 DEG C for t1 h to obtain mixed base oil A; adding 7wt% of neopentyl polyol mixed fatty acid ester and 1wt% of borated fatty acid ester to the mixed base oil A, and stirring at T2 DEG C for t2 h to obtain base oil B; adding 2wt% of zinc dialkyl dithiophosphate to the mixed base oil B, and reacting at T3 DEG C for t3 h to obtain base oil C; and adding x% of rare earth oxide powder to the base oil C, and reacting at 50-60DEG C for t4 h to obtain the finished lubricating oil. The lubricating oil has the advantages of simple preparation method and simple component.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a micro-lubricating oil and a preparation method thereof. Background technique [0002] The preparation method of lubricating oil in the prior art is complex, needs to go through multiple steps, multiple preparation devices, and consumes a lot of manpower and material resources, especially in large-scale preparation, resulting in waste of energy, waste of space, and waste of manpower. Waste, waste of resources and pollution of the environment. [0003] Therefore need a kind of process simple lubricating oil preparation method. [0004] In view of the above-mentioned defects, the creator of the present invention has finally obtained the present invention through long-term research and practice. Contents of the invention [0005] In order to solve the problems of the technologies described above, the technical scheme adopted in the present invention is as follows: [0006] Provi...
