Problems solved by technology

It is worth noting that during the storage and use of lubricating oil, it is difficult for nano-metal particle additives with high chemical activity and surface activity to maintain chemical and physical stability for a long time, and the easy agglomeration of nano-metal particles makes it difficult for them to be used in lubricating oil for a long time. Maintain dispersion stability, which limits the application of nano-metal particle lubricant additives

Abstract

The invention discloses a high-efficiency energy-saving nano anti-wear agent, a preparation method and application thereof. The nano anti-wear agent is made by the following raw materials in weight proportion: 1 to 500 portions of nano metal particles, 100 to 10,000 portions of detergent dispersant, 100 to 10,000 portions of antioxidant, 100 to 5,000 portions of organic high polymer, and 80,000 to 500,000 portions of diluting agent, wherein the nano metal particles are mixture of two or more than two of metal particle molybdenum, boron, chromium, vanadium, titanium, aluminum and cerium. The compositions are mixed according to the proportion, are stirred to react at a specified temperature, are circularly sprayed and dispersed for a plurality of hours through a high-pressure plunger pump, and then form a steady nano-metal eutectic ion organic compound colloid by the dispersion of a high-power ultrasonic device. The nano anti-wear agent has the advantages of good service performance, simple preparation method, and broad application, and can form novel lubricating oil series products with lubricating oil.

Description

technical field [0001] The invention relates to a nanometer antiwear agent, and also relates to a preparation method and application of the nanometer antiwear agent. Background technique [0002] Nanomaterials have attracted extensive attention due to their special physical and chemical properties, and have been initially applied in many fields. In the field of tribology, a great deal of research has been done on nanoparticulate lubricant additives. It has been found that a variety of nano-metal particles as additives can effectively improve the anti-friction, anti-wear and extreme pressure properties of oil. It is worth noting that during the storage and use of lubricating oil, it is difficult for nano-metal particle additives with high chemical activity and surface activity to maintain chemical and physical stability for a long time, and the easy agglomeration of nano-metal particles makes it difficult for them to be used in lubricating oil for a long time. Maintain disp...
