Study of the Composition and Properties of Rolling Oil Produced from Used Motor Oil

Resumo

The effectiveness of using used motor oil as the base for producing rolling oil is studied. A method is proposed for removing resins and aging products from the oil. The obtained results are analyzed. The composition of additives that acts as a triturating material and components that enhance the lubricating, wear-resistance, and protection properties of the rolling oil are determined. Acicular products of urea recrystallization are recommended as materials for fine polishing of parts; oleic acid, as the surfactant. It is shown that additional incorporation of graphenes into the rolling oil promotes running-in of engine parts.
