AI Technical Summary

Benefits of technology

The patent describes a lubricant that has low friction and low wear properties at different temperatures and loads. The lubricant contains a special type of composite ester that has been developed by combining polyester made from alcohol and a carboxylic acid in a specific ratio. This special lubricant can reduce friction and wear even in extreme conditions such as high temperatures and high loads. Additionally, the lubricant has a low viscosity and can be used in both fluid and boundary lubrication states.

Problems solved by technology

However, even in the lubricant composition using the ester-based composition as described above, low friction and low abrasion are not sufficiently compatible, and thus, it is difficult to make low friction and low abrasion compatible at various temperatures and various loads.
