Abstract

The invention discloses a nanoparticle lubricating agent, a preparation method thereof and the application of the lubricating agent in ultrasonic lubrication technology. The nanoparticle lubricating agent comprises the following components in percentage by weight: 85 to 95 percent of base lubricating oil, 0.1 to 1.2 percent of nanoparticle, and 4 to 14.5 percent of dispersing agent. The preparation method comprises the steps: performing mixing and ultrasonic treatment to the base lubricating oil and the dispersing agent, so as to obtain solution A; performing mixing, ultrasonic treatment and high-speed stirring to the base lubricating oil, the nanoparticle and the dispersing agent, so as to obtain solution B; and performing mixing, ultrasonic treatment and grinding to the solution A and the solution B, so as to obtain the nanoparticle lubricating agent. When the nanoparticle lubricating agent is used for ultrasonic lubrication, the nanoparticle plays a rolling role between a friction pair, so that sliding friction of the friction pair becomes rolling friction, and the nanoparticle lubricating agent has excellent antifriction performance and a recovery effect on microdamge on a friction surface. By adopting the nanoparticle lubricating agent, the problem of wear failure of mechanical sliding moving pieces in severe environment can be solved, and the nanoparticle lubricating agent provides an innovative approach for improving and increasing the stability and the service life of equipment, reducing the maintenance time and reducing the maintenance cost.

Description

Technical field [0001] The invention relates to a nano particle lubricant, a preparation method thereof and application in ultrasonic lubrication technology, and belongs to the field of liquid lubrication. Background technique [0002] Friction is a universal phenomenon in nature, and the existence and movement of matter cannot be separated from friction. The negative impact of friction seriously restricts energy utilization, affects the improvement of production efficiency, and brings safety hazards and environmental pollution. According to statistics, energy consumption caused by friction is more than 30%, and more than 70% of equipment failures are caused by component failures caused by wear. For example, the friction loss of the automobile engine accounts for 20% of the total power, the friction loss of the piston aeroengine is about 9% of the total power, and the friction loss of the textile machine accounts for about 85% of the total power. With the development of machine...
