Abstract

The invention relates to lubricating oil and a preparation method thereof, and relates to the field of lubricating oil. The base oil of the lubricating oil is compounded by adopting poly alpha-olefin synthetic lubricating oil and mineral oil, and the base oil is enhanced in anti-oxidative capacity and has preferable intermiscibility with an additive through the synergistic effect of various components, so that a system is more stable. An extreme-pressure abrasion-resistant agent of the lubricating oil adopts organic and inorganic nanometer composite particles, and a polyaniline nanometer particle has excellent environmental stability, corrosion resistance and conductibility, so that the extreme-pressure abrasion-resistant agent not only has the effect of an abrasion-resistant agent, but also has corrosion-resistant property, anti-static property and the like; in addition, the extreme-pressure abrasion-resistant agent of the lubricating oil is reduced in ash content, can react with metal at high temperature to generate a lubricating substance, and forms a protective oil film under the condition of high temperature to provide lubrication; a metallocene catalyst is used for the preparation process of poly alpha-olefin, and compared with a common Ziegler catalyst, the metallocene catalyst has higher activity.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a lubricating oil and a preparation method thereof. Background technique [0002] The commercially available gas engine oil is composed of various base oils and additives with different molecular weights, and has a low flash point. Under the extremely high temperature operating conditions of the gas engine, the evaporation loss is fast, resulting in a large amount of engine oil consumption, and it must be replenished frequently during use. Add oil to keep it well lubricated. At the same time, due to its poor anti-oxidation stability, the oil deteriorates quickly and the oil change period is short. Due to the large evaporation loss and the short oil change interval, the oil consumption is large, which is not conducive to resource conservation. At the same time, the engine oil lost by evaporation volatilizes into the atmosphere or is lost to the environment, and in addition, due to...
