Abstract

The invention provides a graphene composite lubricating grease and a preparation method thereof. Base oil, graphene, a high-molecular acid, calcium hydroxide, a low-molecular acid, and lithium hydroxide are used as raw materials, and after two times of saponification, the lubricating grease is prepared. The base oil and graphene are uniformly fed in two times, and the lubricating grease has advantages of good colloid stability, high dropping point, excellent friction reducing performance and excellent oxidation resistance.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a preparation method of graphene composite lubricating grease. Background technique [0002] Grease is a thick grease-like semi-solid, which is mainly used in the friction parts of machinery 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. [0003] According to the thickener, grease can be divided into two types: soap-based grease and non-soap-based grease. Lithium, sodium, calcium, aluminum, zinc and other metal soaps are commonly used as thickeners for soap base fats, as well as potassium, barium, lead, manganese and other metal soaps. Graphite, carbon black, asbestos and synthetic (such as polyurea base, bentonite) are used as the thickener of non-soap base grease. According to the application, it can be divided into two types: general gr...
