Problems solved by technology

However, the poor dispersion uniformity in the system after the direct addition of graphene directly leads to the uniformity of the dispersion of the micelle-like structure, and the poor uniformity of the obtained lubricating grease, which leads to unsatisfactory indicators such as colloidal stability, dropping point, and anti-friction performance. In addition, the antioxidant properties are not good

Abstract

The invention provides a graphene composite lubricating grease and a preparation method thereof. The invention uses base oil, graphene, high molecular acid, calcium hydroxide, low molecular acid, lithium hydroxide, etc. as raw materials, and undergoes two saponification reactions. A lubricating grease is obtained, the base oil and the graphene are equally divided into two feeds, and the product has good colloidal stability, high dropping point, excellent anti-friction performance and anti-oxidation performance.

Description

Technical field [0001] The present invention relates to the field of grease techniques, and more particularly to a preparation method of graphene composite grease. Background technique [0002] Grease is a thick grease semi-solid, mainly used in mechanical friction portions, lubricating and sealing; also for metal surfaces, filling voids and rust resistance. Grease is mainly made of mineral oil (or synthetic lubricant) and a thickening agent. [0003] The grease can be divided into two categories of saponipate and non-soap-based fats depending on the thickening agent. The thickener of the soap-based fat is commonly used for metal soaps such as lithium, sodium, calcium, aluminum, and zinc, also with metal soap such as potassium, barium, lead, manganese. The non-soap-based thickener is graphite, carbon black, and asbestos and synthetic (such as polyuret, bentonite), which can be divided into three types of general grease and special grease according to the use, for general mechanic...
