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; although the organic metal molybdenum friction modifier improves the anti-friction performance of the oil, the organic molybdenum additives in the prior art cannot be used under extremely harsh working conditions, such as high temperature and high load The lower performance is not good, the maximum non-seize load (PB) and the anti-seizing are not satisfactory

Abstract

The invention relates to a friction modifier for lubricating oil, and concretely relates to a naphthene-yttrium tungsten calcium friction modifier and a production method thereof. The naphthene-yttrium tungsten calcium friction modifier is prepared from the raw materials: yttrium powder, tungsten powder, naphthene, zinc dialkyl dithiophosphate and calcium hydroxide; a production process is safe and environmentally-friendly, and has no pollution to the environment; and the produced naphthene-yttrium tungsten calcium friction modifier has higher antiwear and antifriction, load-bearing and antioxygenic properties without corrosivity, and is added into the lubricating oil, so that the lubricating oil can have a higher antiwear property, a mechanical part can be operated safely and stably under various harsh conditions, and mechanical equipment cannot be corroded.

Description

technical field [0001] The invention relates to a friction modifier for lubricating oil, in particular to a naphthene-yttrium tungsten 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 time. According to rele...
