[0031] Nano diamond lubricants for taxis and buses are prepared as follows:

[0032] 1. Disperse, add 0.3 nanometer diamond to each liter of dispersant OP-10, heat to 60°C, perform strong shearing and stirring for 15 minutes, and let it stand for 8 hours. Nano-diamonds are made by explosive method with a particle size of 1-5nm.

[0033] 2. Emulsify, take out the supernatant, add 150N base oil in a ratio of 1:1.4, mix vigorously for 30 minutes, and then stand for 30 hours to obtain an emulsified composition.

[0034] 3. Add 2% of the above-mentioned emulsified composition to the 60SN base lubricating oil according to the mass ratio, strong shear and stir for 3 minutes, and let it stand for more than 24 hours.

[0035] 4. According to the mass ratio, add 0.4% of T808 pour point depressant to the mixture of step (3), vigorously shear and stir for 5 minutes, and stand for more than 24 hours to obtain the product. After the obtained product was allowed to stand for 2 years, no reunion app...

Embodiment 2

[0037] Nano diamond lubricants for taxis and buses are prepared as follows:

[0038] 1. Disperse, add 0.5g of nano-diamond to each liter of dispersant OP-10, heat to 72℃, and carry out strong shearing and stirring for 18min, and let it stand for 12h. Nano-diamonds are made by explosive method with a particle size of 1-5nm.

[0039] 2. Emulsify, take out the supernatant, add 150N base oil according to the ratio of 1:1.6, stir vigorously for 40 minutes after mixing, and then stand for 50 hours to obtain an emulsified composition.

[0040] 3. Add 2.2% of the above-mentioned emulsified composition to the 60SN base lubricating oil according to the mass ratio, strong shear and stir for 5 minutes, and let it stand for more than 24 hours.

[0041] 4. Add 0.6% of T808 pour point depressant to the mixture of step (3) according to the mass ratio, stir and stir vigorously for 3 minutes, and let it stand for more than 24 hours to obtain the product. After the obtained product was allowed to stand...

Abstract

The invention discloses nano-diamond lubricating oil for taxis and buses. The nano-diamond lubricating oil is characterized by being prepared according to the following method: performing dispersing:adding 0.3-0.5g of nano-diamond into each liter of dispersing agent OP-10, performing heating to 60-80DEG C, carrying out strong shearing and stirring for 10-18min, and conducting standing; performingemulsifying, taking out the supernatant, adding the supernatant into 150N base oil according to a ratio of 1:1.4-1.6, performing mixing, then stirring the substances strongly, and performing standingto obtain an emulsified composition; adding 2-2.5% by mass of the emulsified composition into base lubricating oil, conducting strong shearing and stirring, and performing standing; and adding 0.4-0.6% by mass of a pour point depressant into the mixture obtained in step (3), conducting strong shearing and stirring, and performing standing to obtain the product. The problems that taxies and busesare prone to breaking down and air conditioners cannot be used in summer are solved, the engine service life is prolonged, tail gas emission is reduced, and fuel oil or fuel gas is saved.

Description

Technical field [0001] The invention relates to the technical field of automobile lubricating oil preparation, in particular to a nano-diamond lubricating oil for taxi buses. Background technique [0002] In the 1960s, the United States used black explosives to detonate nano-diamonds in a sealed tank. The former Soviet Union also used the same method to obtain nano-diamonds in the 1970s. In the 1980s, the Lanzhou Institute of Chemistry, Chinese Academy of Sciences, was also used for sealing. The black explosive was detonated in the tank to obtain nanometer diamonds. By the beginning of this century, more than a dozen enterprises and institutions in my country had obtained nano-scale spherical particle diamonds by explosive and detonation methods. Around 2012, in order to increase the yield of nano-diamonds, some companies used black explosives in a sealed tank, and then filled with 3-5 MPa carbon dioxide gas for detonation, so as to increase the yield of nano-diamonds. Increase...
