Abstract The article considers a formation mechanism of the grease with the hybrid dispersed phase including a soap component in the form of the salts of the higher carboxylic acids (in particular, the lithium salt of the 12-hydroxystarinic acid – 12-LioSt) and non-soap component in the form of the highly dispersed particles of the organic or inorganic origin (in particular, the particles of the graphene-like carbon (GLC), thermally expanded graphite). The mathematical regression model of the lithium grease with the hybrid dispersed phase of the 12-LioSt-GLC composition is developed, that makes it possible to determine the component composition (concentration of the lithium 12-oxystearate and GLC) and the synthesis mode (heat treatment temperature of the reaction mass) depending on the required level of the rheological (penetration) and tribological (welding load) properties of the grease.
Keywords grease, hybrid dispersed phase, soap thickener, graphene-like carbon, rheological and tribological properties, regression model, component composition, heat treatment mode
