Problems solved by technology

[0004] Improving the fuel economy of engine lubricating oil by adding friction modifiers can help reduce wear and save energy, which is an important direction for future development; however, although friction modifiers containing elements such as S and P have excellent tribological properties, But it will bring more serious corrosion problems; organic metal molybdenum friction improvement
[0005] Although the anti-friction performance of the oil has been improved, the organic molybdenum additives in the prior art have poor performance under extremely harsh working conditions, such as high temperature and high load conditions. Sex is also unsatisfactory

Abstract

The invention relates to a friction modifier used for lubricating oil, and in particular relates to a naphthene-yttrium, tungsten, silicon, titanium and calcium friction modifier and a production method thereof. The naphthene-yttrium, tungsten, silicon, titanium and calcium friction modifier is produced from raw materials, namely yttrium powder, tungsten powder, naphthene, zinc dialkyl dithiophosphate, silicon powder, titanium powder and calcium hydroxide; the production process is safe and environment-friendly, and no pollution is caused to the environment; and the obtained naphthene-yttrium, tungsten, silicon, titanium and calcium friction modifier has strong anti-wear, anti-friction, bearing and anti-oxidation properties, is non-corrosive, can enable the lubricating oil to have a strong anti-wear effect when being added into the lubricating oil, can enable a mechanical part to safely and stably operate under various harsh conditions and can not cause the corrosion problem on mechanical equipment.

Description

technical field [0001] The invention relates to a friction modifier used for lubricating oil, in particular to a naphthene-yttrium tungsten silicon titanium calcium friction modifier and a production method thereof. Background technique [0002] In the process of mechanical operation, friction and wear are ubiquitous natural phenomena. Friction loses about one-third of the world's energy. Wear is one of the three most important forms of damage and failure of materials and equipment. Modern friction research shows that 1 / 3-1 / 2 of the world's energy is wasted in friction loss in various forms, and the economic loss is huge. Taking a car as an example, only 1 / 3 of the power from the engine is transmitted to the ground, and the rest Power is consumed in self-friction. By reducing self-friction consumption, the power of the engine can be greatly increased, thereby achieving the effect of energy saving. In addition to friction loss, various mechanical wear occurs from time to ti...
