As a good lubricant, olefin-carbon composite nano-copper has been widely recognized by international authorities, and has been applied in some advanced projects in the United States and developed countries in Europe. Its lubricating effect and self-repairing function are not comparable to those of general lubricating oil products and organic additives, and the potential application of this technology is very wide. For example, equipment under various high-load working conditions such as automobiles, ships, aircraft, tanks and mining machinery can greatly improve the wear resistance of high-speed running parts such as precision machinery and aviation. The olefin-carbon composite nano-copper powder lubricating oil additive developed by this technology adopts completely different ideas compared with the lubricating oil organic additive commonly used in the market at present. The nano-copper powder in the olefin-carbon composite nano-copper powder lubricant additive is adhering to the surface of friction workpiece during the oil circuit cycle, which plays a buffer role. At the same time, the nano-copper powder has better chemical stability at high temperature than the organic additive. Therefore, the possible caking and carbonization problems of lubricant at high temperature are fundamentally solved. More importantly, nano-copper powder is fine and soft, which can fill friction defects at any time and play a self-repairing role. The functions of nano-copper lubricating oil additives are as follows: 1. Reduce the friction resistance, improve the effective power of the engine and prolong the life of the engine. 2. Eliminate the damage of initial start-up to engine and save fuel consumption. 3. Improve the efficiency of lubricating oil and ensure the power output of engine. Nano-copper powder in olefin-carbon composite nano-copper powder lubricant additive belongs to ultrafine metal powder material. Technical index The experimental results show that adding 0.1% olefin-carbon composite nano-copper powder additive to lubricating oil can reduce friction coefficient by 30%, wear by 34%, fuel economy by 5% and average fuel consumption by 3%. The technology has reached the level of industrial scale production. The average particle size of nano-copper powder can be adjusted in the range of 2-30 nm. The product repeatability between batches is good and the quality is stable. Application scope The application of this technology has a wide range of applications, which can greatly improve the wear resistance of high-strength and high-load equipment such as precision machinery and high-speed components such as aviation, such as automobiles, ships, aircraft, tanks and mining machinery. When nano-copper or Nano-Bismuth alloy powders were added into lubricating oil as lubricant additives, the lubrication performance was increased by more than 10 times, and the wear of components was significantly reduced,
