Embodiment 1
[0037] Step 1: Weigh 100 g of ricinoleic acid, 10 g of lanthanum oxide, 8 g of boric acid, and 5 g of phosphoric acid (effective concentration 85%) and add them together into a stirrer, stir and heat to 120° C., and fully react for 2 hours.
[0038] Step 2: When the temperature is lowered to below 45° C., 8 g of diethylaminoethanol is added and stirred for 2 hours to obtain a translucent substance, which is a lubricant composition.
[0039] The above lubricant composition was subjected to the four-ball extreme pressure test using the GB / T12583 experimental method, and the test result: P D >6080N.
