Problems solved by technology

However, the research on the use of nano-ferrous sulfide as a lubricating oil additive is still a blank at home and abroad. The applicant of this patent found on the basis of a large number of researches that during the friction test, FeS will not only adhere to the friction surface due to friction. The surface plays the role of reducing friction, and it may decompose, such as the phenomenon that the electrolytic sulfurized layer penetrates into the surface and subsurface during the friction process, which reduces adhesion and abrasive wear, so it can be used as a nano-lubricating oil additive

Embodiment Construction

[0028] First, SEM, ultra-depth of field and secondary particle mass spectrometry were used to characterize the wear surface to study the mechanism of action of lubricating oil additives containing nano-ferrous sulfide (lubrication friction test):

[0029] Under the condition of load of 100N and rotating speed of 200rpm, lubricating oil with 2%, 5% and 10% of lubricating oil without adding and adding nano-ferrous sulfide was used in the experiment after the friction test. The parts of the wear marks were cut with a cutting machine to make observation samples, and observed under SEM: the upper sample was cut with a length of 8 mm and a width of 5 mm, and the lower sample was cut with the claws of the lower three-claw pin. At the same time, SEM is used for surface scanning analysis of micro-area element distribution analysis, and EDX is used for phase composition analysis. The cut samples were wiped with acetone and cleaned in an ultrasonic cleaner until there was no oil stain. T...

Abstract

The invention relates to a lubricant additive containing nano ferrous sulphide granules. The lubricant additive is composed of 1-20wt% of nano ferrous sulphide granules and 80-99wt% of basic lubricating oil, and granularity of nano ferrous sulphide is 10-50nm. The lubricant additive can serve as additives of multifunctional lubricating oil and lubricating grease and also can serve as a repairing antiwear agent for a lubricating system of large-scale mechanical equipment used for various vehicles, ships, petrochemical engineering and mines.

Description

technical field [0001] The invention relates to industrial lubricants, in particular to a lubricating oil additive of nano ferrous sulfide. Background technique [0002] Lubricating oil additives are the main components to ensure the quality of lubricating oil. Although the amount of additives in lubricating oil is much less than that of base oil, its importance is no less than that of base oil, or even more than that of base oil. China is the third largest lubricating oil consumer after the United States and Russia, and with the rapid development of my country's modern machinery industry, especially the automobile industry, higher requirements have been put forward for the variety and quality of lubricating oil. The original anti-friction and anti-wear agents in the oil can no longer meet the performance requirements of modern industry for anti-wear and anti-wear of lubricating oil. [0003] In recent years, with the in-depth development of nanotechnology, it has been found...
