Description

technical field [0001] The invention relates to an additive for lubricating compositions, more specifically, the invention relates to an anti-wear and energy-saving agent for lubricating oil, its preparation method and application, and the international patent classification is C10M. Background technique [0002] As we all know, objects in contact with each other will have a phenomenon that hinders relative motion, that is, friction. Since ancient times, people have tried to reduce the negative effects of friction, and one of the methods is to add lubricants to the contact surfaces. However, when lubricating oil is directly used in automobiles or industrial machinery, etc., its practical performance is not good in many cases. Therefore, various additives are used depending on the type of lubricating oil and their functions. Among them, endowing lubricating oil with anti-friction properties such as reducing friction, reducing wear and preventing sintering is the first conce...
