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.
