Abstract

The invention relates to a metal ceramic lubricating oil couplant, which is composed of: 2-16% of metal ceramic; 1-9% of shielding phenol; 1-8% of diphenylamine; 2-9% of ethoxyphenol; 2-12% of benzotriazole; 1-11% of polymethacrylate; 2-12% of phosphorodithioate; 1-11% of polyalkoxyphenol; 1-12% of polyisobutylene succinate; 1-11% of sulfurized isobutylene; and the balance base oil. The invention adopts the boride base metal ceramic, which has high hardness and melting point, low density and is resistant to corrosion, abrasion and extreme pressure. Thus, the prepared product has strong thermal stability, good high temperature extreme pressure performance, strong oxidation resistance, high wear resistance, and strong demulsification ability.

Description
