Problems solved by technology

The composition uses sodium oxide and phosphorus oxide compounds, among which sodium oxide is extremely corrosive and irritating, and the entire production process must be carried out in an anhydrous state, otherwise violent chemical reactions are likely to occur and crisis production personnel, and it is also dangerous in use; the patent does not specify whether phosphorus oxide is phosphorus dioxide or phosphorus pentoxide, so it cannot be prepared. Phosphorus pentoxide is still a strong corrosive and irritating component. When meeting with water, it will generate a lot of heat and generate phosphoric acid. When it meets sodium oxide, it will react violently and generate a lot of heat. Its operation is extremely dangerous, so the above composition cannot be prepared

Abstract

The invention relates to a composition for treating a friction pair and a preparation method thereof. The composition consists of the following components in percentage by weight: 36-76 percent of aluminum silicate ore nano-powder, 28-58 percent of hydroxyl magnesium silicate nano-powder, 6-8 percent of boric acid or borate and 1-5 percent of dispersing agent. The composition is added into lubricating oil or lubricating grease by 0.1-5 percent by weight, and is uniformly mixed for use. The composition can be used for effectively clearing friction sediments on the surface of the friction pair and in a wear concave surface, so that the metal surfaces of the friction pair are clean and naked; and a self-repairing protective ceramic layer with high hardness and an ultralow friction coefficient is formed on the surface of the friction pair for repairing the surface friction of the friction pair, so that direct contact between the metal surfaces of the friction pair is effectively reduced, the friction coefficient is lowered, and the service life of the friction pair is prolonged. The composition has the advantages of strong dispersing action, capability of well suspending in the lubricating oil, no precipitation when standing for a long time, no reaction with the lubricating oil, no change of the viscosity of the lubricating oil, and the like.

Description

technical field [0001] The invention relates to a composition for treating friction pairs and a preparation method thereof. The composition can be used for the treatment of friction units in the process of mechanical manufacturing, and can also be used for wear control and protection of friction units in the process of mechanical operation. Disassembly and repair. Background technique [0002] Friction is a common phenomenon during the operation of mechanical equipment. The surface of the friction pair is worn during work. When the wear develops to a certain extent, the friction pair will fail due to wear, and it needs to be replaced or repaired to make the equipment work normally. Friction also dissipates additional energy, reducing mechanical efficiency. Friction and wear are one of the three major causes of material and equipment damage and failure, and also consume 30-50% of the world's energy. Therefore, reducing wear and tear, reducing energy consumption, and improvi...
