Definitions
- the present invention relates to a grease composition, and more particularly to a grease composition that is used at a high temperature for a long period of time and has a low evaporation property and a nonflammability.
- grease compositions that have a long service life even in the above-described high temperature environment are effective as low-evaporation greases, because they have characteristics that are difficult to decompose up to a certain temperature.
- its performance is still insufficient, and there has been a demand for a grease composition having a low evaporation property even under a higher temperature environment.
- many grease compositions fall under the category of non-hazardous substances under the Fire Service Law, but when used in an environment that comes into contact with an open fire or in contact with high-temperature metals, carbon, hydrogen, and oxygen are used.
- Grease using the base oil as the main component burns.
- grease based on PFAE which is a grease using nonflammable base oil, may decompose at high temperatures and generate toxic gases. Although there was no problem, the lubricity in the boundary lubrication region was inferior.
