Abstract

The invention discloses vegetable oil based ionic liquid microemulsion type nano lubricating oil and a preparation method thereof. The method comprises the following steps: dissolving copper salt in vegetable oil under the condition of stirring at 20-90 DEG C, thus obtaining a component A; dissolving reducer into ionic liquid to obtain a component B; adding surfactant into the A to obtain a component C; and uniformly and dropwisely adding the component B into the component C, and performing thermostatic reaction to obtain the vegetable oil based ionic liquid microemulsion type nano lubricating oil containing nano copper particles. According to the invention, the lubricating oil base oil is used as a carrier, and the nano copper particles are in-situ synthesized therein. The synthesis method simplifies the production process of the lubricating oil product, lowers the production cost, and effectively solves the problem of aggregation between the lubricating oil base oil and the additive particles. The vegetable oil based ionic liquid microemulsion type nano lubricating oil, prepared by the invention, is high in dispersity and high in storage stability, and has excellent heat stability, antifriction property and abrasion resistance.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a vegetable oil-based ionic liquid lubricating oil containing nanoparticles and a preparation method thereof. Background technique [0002] With the increasing attention of green chemistry, ionic liquid microemulsions have received more and more attention, and its application fields also cover the fields of material preparation, energy development, separation and extraction, etc. Recently, studies have shown that the ionic liquid microemulsion prepared with vegetable oil as the non-polar phase and ionic liquid as the polar phase has excellent viscosity-temperature characteristics and anti-wear properties, and is a new type of lubricating oil base with great development prospects. Oil. In order to further enhance the lubricating performance of vegetable oil-based ionic liquid microemulsion lubricating oil base oil, it is an inevitable trend to add nano additives to it.
