Problems solved by technology

What CN101307269A discloses is the low-noise lubricating grease prepared with composite titanium soap, it is characterized in that through suitable formula technology, the composite titanium base lubricating grease of preparation solves the phenomenon that existing lubricating grease makes the vibration speed of the bearing unstable and there is noise, but The process conditions it describes are very broad and do not show how its properties are controlled
The composite titanium base lubricating grease disclosed by CN101117605A has outstanding mechanical stability and extreme pressure and wear resistance, and its preparation method also adopts a two-step method, and the reaction time is longer
US5387351 discloses composite titanium-based grease and its preparation method. The preparation method described adopts a one-step reaction, but the reaction time is as long as 3-10 hours, and the industrial production cost is very high. The research on the above-mentioned composite titanium-based grease mainly focuses on In improving its performance through additives, the preparation method described uses a two-step method, and the reaction time is longer

The compound titanium-based lubricant is good excellent mechanical stability and oxidization stability, and especially good in water resistance property.

Description

technical field [0001] The invention relates to a lubricating grease and a preparation method thereof, in particular to a composite titanium-based lubricating grease and a preparation method thereof. Background technique [0002] Although transition metals are widely distributed in nature, and transition metal-organic compounds have been widely used, there are few studies on greases using fatty acid soaps prepared from transition metals as thickeners. In 1961, Markley prepared titanium stearate soap, but the dropping point was only 62 °C, so it was not used as a thickener for grease. It was not until the 1990s that researchers in India succeeded in developing a high-performance, multifunctional complex titanium-based grease. From the perspective of toxicity and safety, the research shows that the complex titanium-based grease is safe for producers and users, and the complex titanium-based grease prepared with vegetable oil has good biodegradability. From the point of view o...
