Embodiment Construction
[0007] The technical solution adopted in this specific embodiment is: a potassium borate amide urea antiwear agent with good hydrolysis resistance and compatibility is composed of the following raw materials: potassium hydroxide, boric acid, ethylenediamine, isocyanate, octadecylamine; Potassium+boric acid+ethylenediamine+isocyanate+octadecylamine mol ratio is 1: 2: 1: 1: 1; Its preparation method comprises the following steps: one, make the potassium amide urea antiwear agent of borate of 100kg, first mix 27.6 Add 500kg of lubricating base oil 500SN into the reactor, dissolve 6kg of ethylenediamine and 27kg of octadecylamine, add 15.8kg of isocyanate to react into a paste, add 240kg of boric acid in turn, then add 112kg of potassium hydroxide, and react until Potassium borate amide urea was obtained at 220°C as a medium; 2. Potassium borate amide urea was mixed with potassium tetraborate to obtain a finished potassium borate amide urea antiwear agent.
