Abstract

The invention discloses a multifunctional lubricating oil additive. The additive is composed of the following raw materials in parts by weight: 50-100 parts of morpholine ionic liquid; 0.8-7.5 parts of detergent; 1.2-2.6 parts of antirust agent; 7 to 16 parts of agent; and 0.2 to 3.8 parts of foam inhibitor. The multifunctional lubricating oil additive of the present invention is applied in steel / steel or steel / aluminum friction pairs, which significantly improves the friction reduction and anti-wear performance of the lubricating oil additive in the friction pair, and at the same time improves its extreme pressure bearing performance, and the friction pair Small loss and long service life.

Description

technical field [0001] The invention relates to the technical field of additives, in particular to a multifunctional lubricating oil additive and its application. Background technique [0002] The operation of equipment is inseparable from lubricating oil additives, and lubricating oil cannot be separated from lubricating oil additives. Lubricating oil additives are the essence of various modern high-grade lubricating oils. According to statistics, about 30% of energy consumption is on friction, and 70% of damaged parts are scrapped by wear and tear. Therefore, improving lubricating performance to reduce friction, wear and prevent sintering is of great significance to the national economy. Additives commonly used in lubricating oil are divided into antioxidants, anti-wear agents, friction modifiers (also known as oily agents), extreme pressure additives, detergents, dispersants, foam inhibitors, anti-corrosion and anti-rust agents, and flow point improvement. Additives, vi...
