Abstract

The invention discloses a special lubricating oil for bearings and a preparation method thereof. The special lubricating oil for the bearings is prepared from the following components in parts by weight: 50 to 80 parts of mineral base oil, 6 to 12 parts of chlorinated paraffin, 2 to 6 parts of dodecyl alcohol ester, 1 to 3 parts of monosuccinimide, 5 to 9 parts of tributyl acetylcitrate, 3 to 10 parts of polyvinyl acetate, 4 to 12 parts of nanometer ferric tetroxide microsphere, 3 to 8 parts of dioctyl terephthalate, 1 to 3 parts of benzotriazole, 1 to 3 parts of nanometer lanthanum hexaboride, 2 to 5 parts of succinimide, 2 to 5 parts of calcium alkyl benzene sulfonate, and 3 to 6 parts of acetophenone. The special lubricating oil for the bearings has the advantages that the viscosity index is high, the anti-wear property is high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a special lubricating oil for 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), cycloalkyl aromatics And oxygen-containing, nitrogen-containing, sulfur-containing organic compounds and non-hydrocarbon compo...
