Embodiment Construction

[0012] The present invention adds 0.05% to 4.0% cholesterol in lubricating oil as an additive, heats to 80°C to 90°C, stirs evenly, and then cools to normal temperature for use. Described lubricating oil is machine oil.

[0013] The molecular formula of cholesterol is shown in Figure 1. The structure of cholesterol is characterized by a β-configured hydroxyl group on C-3, a double bond between C-5 and C-6, and a A hydrocarbyl side chain of 8 carbon atoms.

[0014] Adding 0.05%-4.0% (weight) of cholesterol to the lubricating oil, then heating the lubricating oil and stirring the lubricating oil, the cholesterol is evenly dispersed in the lubricating oil. After the lubricating oil cools down, it can be used.

[0015] Fig. 2, Fig. 3, Fig. 4, Fig. 5 are typical case experiment results of the present invention, evaluate the tribological mechanical property of lubricating oil with the four-ball test of MMW-1 type vertical universal friction and wear testing machine.

Abstract

The present invention discloses preparation process of lubricating oil containing cholesterol. Cholesterol in 0.05-4.0 wt% as additive is added into lubricating oil through heating to 80-90 deg c and stirring, before being cooled to normal temperature. Cholesterol may be added into lubricating oil easily without pollution to reduce friction and raise wear resistance of gears, worms, rolling bearings, sliding bearing and other mechanical parts, and raise the gluing resistance of the friction pair.

Description

technical field [0001] The invention relates to lubricating oil, in particular to a preparation method of lubricating oil containing cholesterol. Background technique [0002] The anti-adhesion ability of existing mechanical oil is low. In order to improve the wear resistance and anti-friction performance of lubricating oil and grease, and improve the anti-adhesion ability, people used to add nano-diamond powder, nano-calcium carbonate, etc. to improve the anti-adhesion ability of friction pairs. . Since nano-powders are easy to agglomerate and difficult to disperse, it is necessary to modify the surface of nanoparticles to achieve better dispersion. Contents of the invention [0003] The object of the present invention is to provide a kind of preparation method of lubricating oil containing cholesterol. [0004] The technical scheme adopted in the invention is: adding 0.05% to 4.0% cholesterol in the lubricating oil as an additive, heating to 80°C to 90°C, stirring even...
