Abstract

The invention discloses a lubricant for machine tool bearings and a preparation method of the lubricant, and belongs to the technical field of lubricants. The lubricant comprises the following components by weight: 30 to 50 parts of compound base oil, 10 to 20 parts of paraffin, 2 to 10 parts of modified graphene, 5 to 10 parts of polytetrafluoroethylene particles, 2 to 5 parts of tri-m-tolyl phosphate, 5 to 15 parts of zinc naphthenate, 1 to 3 parts of polyisobutene, and 8 to 12 parts of monoethanol amine. The lubricant has the advantages that the components are simple; the cost is low; the viscosity index is relatively high; the wear resistance performance is high; the service life is long. The preparation method has the advantages that the steps are simple; the environment is protected; the implementation is easy.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a lubricating oil for machine tool bearings and a preparation method thereof. Background technique [0002] Bearing lubricating oil is lubricating oil used on bearings to lubricate, cool down, resist pressure, and prolong the life of bearings. Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. Base oil is refined from crude oil, generally alkanes (linear, branched, multi-branched), cycloalkanes (monocyclic, bicyclic, polycyclic), aromatics (monocyclic aromatics, polycyclic aromatics), cycloalkylaromatics And oxygen-containing, nitrogen-containing, sulfur-containing organic compounds and non-h...
