Abstract

The invention discloses interlayer pillared N, N'-dimethylpiperazine zirconium phosphate lubricating grease and a preparation method thereof. The lubricating grease comprises, by weight, 80-97 parts of base lubricating grease, 1.0-18.0 parts of [C6H16N2] 0.5Zr (H0.5PO4)2H2O, 1.0-2.0 parts of antioxidants and an additive, the additive comprises a layered zirconium phosphate material [C6H16N2] 0.5Zr (H0.5PO4)2H2O, an interlayer of the layered zirconium phosphate material is provided with N, N'-dimethylpiperazine and water molecules, the base lubricating grease is manufactured, the additive is added, and mixture is stirred for 5 minutes and grinded into grease by a three-roller machine. The lubricating grease is provided with interlayer pillared N, N'-dimethylpiperazine zirconium phosphate materials, and friction reducing capacity and abrasion resistance of the lubricating grease are remarkably improved.

Description

technical field [0001] The present invention relates to a kind of interlayer pillared N, N'-dimethylpiperazine [C 6 h 16 N 2 ] 0.5 Zr(H 0.5 PO 4 ) 2 h 2 A lubricating grease of O material and a preparation method thereof belong to the technical field of lubricating grease and its preparation. Background technique [0002] Grease is a semi-fluid or solid lubricating product composed of base oil and thickener. Grease is used in a wide range of fields, almost covering industrial machinery, transportation industry, electronic information, aviation and aerospace and other fields. Reasonable use of grease additives can effectively improve the lubricating performance of grease and improve the friction environment of friction pairs, especially for mechanical equipment operating in harsh environments such as low temperature, high speed, and heavy load, so as to protect friction pairs, reduce friction, and save energy. etc. purpose. Therefore, it is necessary to continuously...
