Problems solved by technology

[0002] With the continuous development of science and technology, the existing lubricating oil in the liquid state is no longer suitable for the technical requirements of motor vehicles and sports machinery under high speed, high temperature, heavy load and high pressure, especially when the friction interface is caused by processing defects or wear. Liquid lubricating oil cannot make up for flaws, so people are constantly developing more effective lubricating materials to improve the performance of liquid lubricating oil
The U.S. Patent No. 4808324 discloses a special lubricant for rolling mills for rolling profiles. It still has a certain lubricating effect when the temperature of moving parts is as high as 1000 ° C or more, but it can only be used on rolling mills. certain limit
The U.S. Patent No. 4634545 discloses a rail lubricant, its main component is an incomplete mixture of graphite and oil carrier, this patent is a lubricant specially developed for rail, so its application The scope is also limited
A colloidal suspension friction modifier produced by the Cromwell orgnlzatlon company in the United States. This modifier is mainly added to engine oil to improve its lubricating performance. It is made of 0.5 μm natural graphite and other materials. Due to the natural stone The low purity of the ink itself directly affects its lubricating performance. If flake graphite is used, although the purity can be improved, the cross-section of the flake graphite has no lubricating properties when the particle monomer is less than 10 μm.

Embodiment 1

[0011] Using graphitized pyrolysis pure carbon nanoparticles as raw material, using model SD gasoline engine oil as medium, its weight content is gasoline engine oil accounts for 99.9%, graphitization pyrolysis pure carbon nanoparticles accounts for 0.1%, and its homogeneous mixing method It is: add a variable diameter tee at the 300mm position of the pump body inlet of the main pumping pipeline at the end of the gasoline engine oil production line, and use the negative pressure of the pipeline to suck the graphitized pyrolysis pure carbon nano-particle raw material into the pipeline to make it compound in the gasoline engine oil It is sent into the oil storage tank together with the gasoline engine oil, and then sent back to the oil storage tank through the oil return pipe. In this way, the mixing can be completed after 3 cycles to form a solid-liquid suspension gasoline engine oil lubricating oil .

Embodiment 2

[0013] Using graphitized pyrolysis pure carbon nanoparticles as raw material, using model CB diesel engine oil as medium, its weight content is gasoline engine oil accounts for 99.5%, graphitized pyrolysis pure carbon nanoparticles is 0.5%, and its homogeneous mixing method It is: Add a variable diameter tee at the 300mm position of the pump body inlet of the main pumping pipeline at the end of the diesel engine oil production line, and use the negative pressure of the pipeline to suck the graphitized pyrolysis pure carbon nanoparticle raw material into the pipeline to make it compound in the diesel engine oil It is sent into the oil storage tank together with the diesel engine oil, and then sent back to the oil storage tank through the oil return pipe. In this way, two cycles can complete the mixing and form a solid-liquid suspension diesel engine oil lubricating oil .

Embodiment 3

[0015] Using graphitized pyrolysis pure carbon nanoparticles as raw material and vehicle gear oil with a model of 75W as the medium, its weight content is 99.90% for vehicle gear oil and 0.1% for graphitized pyrolysis pure carbon nanoparticles. The uniform method is: add a variable diameter tee at the 300mm position of the pump body feed inlet of the pumping main pipeline at the end of the vehicle gear lubricating oil production line, and use the negative pressure of the pipeline to suck the graphitized pyrolysis pure carbon nanoparticle raw material into the pipeline to make it composite After being put in the vehicle gear oil, it is sent to the oil storage tank together with the vehicle gear oil, and then sent back to the oil storage tank through the oil return pipe. After 5 cycles in this way, the mixing can be completed and a solid-liquid suspension is formed. Body vehicle gear oil lubricating oil.

It has the features of lowering noise, reducing vibration and wear, saving fuel oil, prolonging the service life of moving parts and lubricant oil, and improving tail gas.

Description

Technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to a solid-liquid suspension lubricating oil. Background technique [0002] With the continuous development of science and technology, the existing lubricating oil in the liquid state is no longer suitable for the technical requirements of motor vehicles and sports machinery under high speed, high temperature, heavy load and high pressure, especially when the friction interface is caused by processing defects or wear. Liquid lubricating oil cannot make up for flaws, so people are constantly researching and developing more effective lubricating materials to improve the performance of liquid lubricating oil. The U.S. Patent No. 4808324 discloses a special lubricant for rolling mills for rolling profiles. It still has a certain lubricating effect when the temperature of moving parts is as high as 1000 ° C or more, but it can only be used on rolling mills. Certain restrictions....
