Embodiment 1

[0042] The microcarbon sphere oil-based lubricating fluid component is 0.5% microcarbon spheres accounting for the total mass of the lubricating fluid, and the balance is paraffin oil. The particle size of the microcarbon spheres is 450nm. Under the condition of a load of 10N, the research contains 0.5% microcarbon spheres The anti-friction performance of the lubricating fluid was tested under the same conditions using paraffin oil without microcarbon spheres as the lubricating fluid, and the test sample was made of stainless steel base material. attached figure 1 The change of the friction coefficient of the system before and after adding micro carbon spheres is given when paraffin oil is used as the lubricating medium. attached by figure 1 It can be seen that when lubricating with pure paraffin oil without carbon balls, there is a long running-in period in the early stage of the lubrication process, reaching about 600s. After the running-in period, the friction coefficient ...

Embodiment 2

[0047] The components of the micro-carbon sphere oil-based lubricating fluid are micro-carbon spheres accounting for 0.5% of the total mass of the lubricating fluid, Span 80 accounting for 1% of the total mass of the lubricating fluid, and the balance being paraffin oil. The particle size of the micro-carbon spheres is 500nm. Under the condition of 10N, study the anti-friction performance of the lubricating fluid containing 0.5% carbon microspheres and 1% Span 80 in the total mass of the lubricating fluid, and use the lubricating fluid containing only 1.0% Span 80 without microcarbon spheres For comparative example, the test sample is a stainless steel base material. attached image 3 The friction coefficient of 0.5% micro carbon ball + 1% Span 80 + paraffin oil and 1% Span 80 + paraffin oil lubricating fluid changes with time, according to the attached image 3 It can be seen that the friction coefficient of the lubricating fluid after adding microcarbon spheres is relativel...

Embodiment 3

[0052] Micro-carbon sphere oil-based lubricating fluid: micro-carbon spheres accounting for 0.5% of the total mass of the lubricating fluid, Span 80 accounting for 5% of the total mass of the lubricating fluid, and the balance being paraffin oil. The micro-carbon spheres have a particle size of 450nm and a load of 10N Under the same conditions, the anti-friction performance of lubricating fluid containing 0.5% microcarbon spheres and 5% Span 80 was studied, and the lubricating fluid containing only 5.0% Span 80 without microcarbon spheres was used as a comparative example, and the test sample was stainless steel base material. Using scanning electron microscopy and two-dimensional profile measurement to characterize the wear marks on the substrate after the friction experiment, it was found that the lubricating fluid containing only 5.0% Span 80 and the lubricating fluid containing 0.5% microcarbon spheres and 5% Span 80 In contrast, the wear pattern of the substrate is not ob...

Abstract

The invention provides a micro-carbon sphere oil base lubricating liquid which comprises a micro-carbon sphere and a lubricating media, the mass of the micro-carbon sphere accounts for 0.1%-10% of the total mass of the lubricating liquid, the balance is lubricating media, and the grain diameter of the micro-carbon sphere is 400-550 nm; the micro-carbon sphere oil base lubricating liquid can also contain a non-ionic surface active agent. The micro-carbon sphere oil base lubricating liquid doesn't contain S and P components and is environment-friendly, and the anti-attrition effect of the lubricating liquid is improved by the aid of the added micro-carbon sphere. The addictive of the lubricating liquid has the advantages that the running in time is shortened, the friction is reduced and the abrasion reduction effect is good, and accordingly, the lubricating liquid has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of lubricating fluid, in particular to a microcarbon sphere oil-based lubricating fluid and a preparation method thereof. Background technique [0002] Lubricating oil is often used in the connecting parts of automobiles, locomotives or various mechanical parts to reduce the wear and tear of parts due to contact friction. Lubricating oil generally includes lubricating medium and additives. Due to different components, the additives can make the lubricating fluid have multiple functions such as cleaning, dispersion, viscosity, anti-friction performance and anti-oxidation performance. Among them, the anti-friction performance involves the wear of metal materials. In the case of increasingly scarce metal materials, lubricating fluids with good anti-friction properties have attracted extensive attention from researchers at home and abroad. [0003] Ma Haibing and others made two kinds of O-O-bis-(dodecyl alcoho...
