Abstract
The possibility of using oilseed waste as a raw material base for obtaining high-temperature greases was studied. Due to the easy availability of research material, phosphate concentrate, which is the main waste production of vegetable oil production, is selected. In addition, the use of phosphatide concentrate, because of its biological origin, solves problems associated with the influence of lubricants on the environment. In solving the problem, a method for obtaining high-temperature metallurgical grease based on a phosphatide concentrate in two stages was developed. In the first stage, the phosphatidic concentrate was subjected to amidation of N,N′-bis(2-hydroxyethyl)ethylenediamine, to produce of additive for lubricating material. Modified phosphate concentrate behaves as a non-ionogenic surfactant in alkaline and neutral media and as a cationic surfactant in acidic medium. This additive forms an unusual micellar structure in oil solutions, actively solubilizes water and other hydrophilic components, and due to the amphiphilic structure and adhesion on metal surfaces forms a solid adsorption layer, which prevents the course of corrosion processes and improves the tribological characteristics of lubricating material. In the second stage, this additive was mixed with petroleum oil, a hydrocarbon solvent, a promoter, and alkaline earth metal hydroxide, carbonization was performed and a thickener of greases was formed. The tests of rheological and tribological, properties of the obtained greases and their comparison with the properties of commodity metallurgical greases have been performed. It is shown that according to the basic parameters obtained products have revealed better main properties than commodity greases. The obtained results indicate the expediency of using a phosphatide concentrate as a raw material for the production of lubricants.
