Compound calcium sulfonate base lubricating grease and preparation method thereof

Abstract

The invention discloses compound calcium sulfonate base lubricating grease and a preparation method thereof. The key points of the technical scheme of the invention lie in that the compound calcium sulfonate base lubricating grease is prepared by adding calcium sulfonate in an inorganic substance and an organic substance compound calcium soap and thickening base oil, and an arylamine antioxidant is added in a thickening procedure. The high-performance compound calcium sulfonate base lubricating grease is prepared and acquired in a certain raw material ratio and operation condition. By using the compound calcium sulfonate base lubricating grease and the preparation method, the cost of a user is reduced; a product has favorable water resistance, lubricating property and high temperature resistance, cannot be emulsified and degreased, and is not easy to run off; the service life of mechanical equipment is prolonged; the maintenance time of the equipment is decreased; the production efficiency of the equipment is improved; a raw material formula is reasonable; the cost is low; the emission of three wastes does not exist in a production procedure; the compound calcium sulfonate base lubricating grease and the preparation method are environment-friendly while an industrial requirement is met; and the preparation method is a green production process.

Description

technical field

[0001] The invention relates to a composite calcium sulfonate-based lubricating grease and a preparation method thereof, in particular to a composite calcium sulfonate-based grease with excellent high-temperature performance and thermal reversibility, which uses a composite calcium soap containing calcium sulfonate salt as a thickening agent. Lubricating grease and method for its preparation. Background technique

[0002] High base value complex calcium sulfonate-based grease has excellent extreme pressure, anti-wear performance, water resistance, salt spray resistance, corrosion resistance, high dropping point, good thermal stability at high temperature, etc., and is widely used in High-temperature, heavy-duty and water-rich environments such as automobiles, steel, mines, and papermaking. At present, there are two main processes for preparing complex calcium sulfonate-based grease: one is to introduce CO into the system of mixing neutral calcium sul...
