Abstract:
Compositions containing a reverse micelle comprising a first compound and a second compound are disclosed, wherein the second compound is configured to change conformation in response to a stimulus, a first conformation selected for formation of the reverse micelle, and a second conformation selected for disruption of the reverse micelle; and wherein the first compound is selected to interact with the first conformation of the second compound to form the reverse micelle.
Abstract:
The invention relates to a lubricant in the form of grease or thick lubricating gel or transmission oil, as well as motor or universal oils with a myriad of applications. As a result of its contents presented in the patent application is characteristic of low coefficient of friction ranging from 0.055 to 0.062. As the main component, the contents of the discussed lubricant includes three or four stearates of metals or hydroxistearates of metals, which interact and cause a noticeable reduction of friction drag on the lubricated surfaces. Additionally, these substances may include a number of other solid or liquid elements, which maintain low friction drags and, furthermore, improve the lubricant through increasing its load capacity, antirust characteristics, shear strength, etc. The lubricant made according to the invention underwent comparative tests against other greases and greasing oils, the accounts of which are included in the application as diagrams, descriptions of research tests and examples of the contents of the lubricant products.
