A preparation method of the functional graphene lubricating grease material has the advantages of simplicity, low preparation cost, wide application range, and worthiness promoting.

Description

technical field [0001] The invention relates to the technical field of grease, in particular to a functional graphene grease material and a preparation method thereof. Background technique [0002] Grease is a stable solid or semi-solid product composed of base oil with thickener dispersed in liquid lubricant, and its appearance is black, white, translucent, beige. Grease is used in mechanical friction parts to lubricate and seal; it is also used on metal surfaces to fill gaps and prevent rust. Grease is mainly prepared from mineral oil (or synthetic lubricating oil) and thickener, and is mainly used in the lubrication, protection and protection of mechanical moving parts such as gears and bearings, thereby reducing the risk. Lubricating grease can be divided into soap-based grease and non-soap-based grease according to the thickener. Among them, the thickener of soap-based grease is commonly used metal soaps such as lithium, sodium, calcium, aluminum, and zinc, and potassi...
