Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a lubricating oil for mechanical equipment and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication and buffering. The purpose of lubrication is to reduce friction and reduce wear. Lubricating oil can also take away the heat generated by friction, thereby reducing the temperature of the friction surface. [0003] The lubrication management of mechanical equipment is an important part of the technical management of mechanical equipment, and it is also an important part of equipment maintenance work. Doing a good job in equipment lubrication is to ensure the normal operation of equipment, reduce equipment wear, prevent and reduce equipment accidents, and reduce po...
