| titleOfInvention | Preparation method and application of ultra-thin additive capable of ultra-high loading |
| abstract | The invention discloses a preparation and application method of an ultra-thin hydrotalcite additive capable of realizing an ultra-high load (higher than 1500N), and belongs to the field of lubricating materials. The ultra-thin nano-hydrotalcite flakes prepared by the constant pH co-precipitation method have a longitudinal scale of 1-5nm (about 2-8 layers), and are dispersed and dissolved in ultra-pure water at a solid-to-liquid ratio of 0.1%-2%. It can maintain a stable state for as long as 1 month, which is much more stable than the hydrotalcite stripped by formamide solution. After centrifuging the above colloidal solution, it is transferred to an alcoholic solution, and then transferred to a lubricating oil system by thermal evaporation, so that a clear and transparent colloidal solution can be prepared. The metal elements in the ultra-thin nano-hydrotalcite sheets of the present invention are in unsaturated coordination bonds, and the coordination-unsaturated nano-sheets have extremely high chemical activity in the high-temperature working area, and promote the formation of dense protective friction on the surface of the friction pair film, achieving an ultra-high load capacity of the lubricating fluid. |
