Abstract

The invention relates to the technical field of a composite calcium-sulfonate-base grease and preparation thereof, particularly a composite calcium-sulfonate-base lubricating grease and a preparation method thereof. The preparation method of the composite calcium-sulfonate-base lubricating grease comprises the following step: 1. respectively weighing 20-30 parts by weight of high-base-number petroleum calcium sulfonate with the total base number of 200-400 mg KOH/g, and 44-55 parts by weight of high-viscosity-index base oil with the viscosity index of 90-120. The invention has the advantages of simple technique, accessible raw materials and safe working environment, is convenient for operation, and effectively lowers the energy consumption; the product obtained by the method provided by the invention has excellent properties, and can satisfy the product index requirements without adding any additive, and thus, the production input cost of the product is lower than that of any other high temperature grease; no harmful substance is generated in the product production and use process, so the composite calcium-sulfonate-base grease is harmless to the human body; and the composite calcium-sulfonate-base grease can be recycled and reutilized to maximize the use of energy sources, thereby completely satisfying the requirements of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of composite calcium sulfonate-based grease and its preparation, and relates to a composite calcium sulfonate-based grease and a preparation method thereof. Background technique [0002] Composite calcium sulfonate-based grease is a new type of high-efficiency grease product. It is a kind of lubricating grease product with excellent performance, which is made of high alkali value sulfonate calcium soap, fatty acid calcium soap and inorganic calcium salt compound thickened base oil. However, there are still the following problems: [0003] 1. The thickening ability of the high base value thickener to the base oil and the performance of other additives restrict each other. Compatibility with base oil and compatibility of thickener and additives should be considered during production; [0004] 2. The normal pressure reaction temperature is above 100 degrees, the reaction time is long, and the energy consum...
