Embodiment 1

[0016] Add 1.5% of N-3-dimethylaminopropyl-perfluorohexylsulfonamide to the base oil, mix well at 60-70°C; then cool down to 30-40°C, add 0.07% of the base oil weight % of neodymium acetate and mix well.

Embodiment 2

[0018] Add N-3-dimethylaminopropyl-perfluorohexyl sulfonamide accounting for 2% of the weight of the base oil to the base oil and mix evenly at 60-70°C; then cool down to 30-40°C and add 0.1% of the weight of the base oil % of neodymium acetate and mix well.

Embodiment 3

[0020] Add 0.5% of N-3-dimethylaminopropyl-perfluorohexylsulfonamide to the base oil, mix well at 60-70°C; then cool down to 30-40°C, add 0.05% by weight of the base oil % of neodymium acetate and mix well.

Abstract

The invention discloses N-3-dimethylamino propyl-perfluorocarbon sulfonamide-containing lubricating oil and a preparation method thereof, and belongs to the technical field of lubricating oil. The N-3-dimethylamino propyl-perfluorocarbon sulfonamide-containing lubricating oil is prepared from basic oil and an additive, wherein the additive is prepared from N-3-dimethylamino propyl-perfluorocarbon sulfonamide and neodymium acetate. After the N-3-dimethylamino propyl-perfluorocarbon sulfonamide and neodymium acetate are added into the basic oil, the anti-wear and friction-reducing performance is greatly improved, the antiscuffing capacity of a friction pair is enhanced, and the bearing performance of the lubricating oil is also improved. Furthermore, N-3-dimethylamino propyl-perfluorocarbon sulfonamide and neodymium acetate are easily dispersed in the basic oil, and no agglomeration phenomenon is caused.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a lubricating oil containing N-3-dimethylaminopropyl-perfluorohexylsulfonamide and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oils are generally made by mixing base oils with additives. Lubricating oil additives are one or several compounds added to lubricants to obtain new properties or improve some existing properties of lubricants. [0003] The lubricating oil in the prior art has poor anti-wear and anti-friction performance. In order to improve the anti-wear and anti-friction performance of lubricating oil and grease, and improve the anti-adhesion ability, nano-diamond powder, nano-calcium carbonate, nano-g...
