Problems solved by technology

[0003] However, because lubricating oil is mostly used in harsh working environments such as high temperature and high pressure, its original performance is prone to change, and even no longer plays the role of reducing friction, cooling, sealing, buffering, rust prevention, cleaning and neutralization. As a result, about 30% of the mechanical energy is consumed on friction every year, and 80% of the damaged equipment is scrapped by wear and tear.
In addition, since the lubricating oil is in contact with the air during use, the temperature of the friction parts of various mechanical equipment will increase due to friction, and various metal materials in the equipment, such as copper and iron, will act as catalysts to accelerate the oil production. Oxidation and deterioration of the lubricating oil will eventually increase the viscosity of the lubricating oil, generate acidic substances to corrode metal materials, or produce various carbon-like or asphalt-like precipitates such as paint films to block the pipeline. adverse effects; and the lubricating oil is also easily oxidized and loses its proper lubricating effect

Description

technical field [0001] The invention belongs to the field of lubricating oil, in particular to an anti-extreme pressure and oxidation-resistant lubricating oil and a preparation method thereof. Background technique [0002] Mechanical lubricant mainly refers to the liquid lubricant coated on the surface of a certain part of the machine to reduce friction and protect machinery and workpieces. It mainly plays the role of reducing friction, cooling, sealing, buffering, rust prevention, cleaning and neutralization. Generally, it is the product of fractionated petroleum, and it is also extracted from animal and vegetable oils, also known as "lubricating grease". Non-volatile oily lubricants are divided into three categories according to their sources: moving oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. The most important properties of lubricating oil are viscosity, oxidation stability and lubricity, which are closely related to the composition of l...
