Carbon material-containing lubricating grease and preparation method thereof

Abstract

The invention discloses carbon material-containing lubricating grease and a preparation method thereof. The lubricating grease is prepared from, by weight, 80-90 parts of base oil, 15-20 parts of a lithium-based thickening agent and 1-5 parts of an additive, wherein graphene or a multi-walled carbon nanotube or a mixture of the graphene and the multi-walled carbon nanotube is adopted as the additive. Compared with heat-conducting lubricating grease sold on the market, the carbon material-containing lubricating grease has the advantages that the product raw materials are easy to obtain, and the preparation technology is simple; the more excellent heat conductivity is achieved and is specifically embodied in the fact that the heat conductivity coefficient is high, and a heat fin is rapidly cooled. The lubricating grease can be applied to a high-temperature environment or an environment where too much heat is generated due to long-term friction, can not only achieve the lubricating protection effect but also lower the temperature of the friction surface and can keep normal operation of a machine.

Description

technical field [0001] The invention relates to lubricating grease technology, in particular to a lubricating grease of carbon-containing material and a preparation method thereof. Background technique [0002] Lithium-based grease is one of the fastest-growing, most widely used, and most promising grease products since the 1940s. It has a wide range of raw materials, good high and low temperature performance, extreme pressure and anti-wear performance, and Rust and corrosion resistance and other advantages, it is applied to all walks of life. [0003] Graphene is a two-dimensional planar carbon nanomaterial with a single atomic layer thickness, which is connected by sp2 hybridized carbon atoms. This special structure endows graphene with unique physical and chemical properties, such as excellent electrical, mechanical, optical and Thermal properties. Therefore, it has broad application prospects in the fields of micro-nano electronics, energy, composite materials, and bio...
