[0004] Calcium carbonate whisker is another new product after nano-calcium carbonate. It is rod-shaped and needle-shaped single crystal under the microscope, generally in the aragonite crystal form, with good comprehensive performance, high friction coefficient, high wear resistance and heat resistance. , and can reduce vibration, anti-skid, noise reduction, and absorb waves during use, which can extend product life by 30%, and the source of raw materials is abundant and the price is low. Currently, it is widely used in plastics, rubber, paint, paper, cement and other materials. , the use effect is good; but as a crystal with the same composition and similar structure as the calcite crystal calcium carbonate, the application of calcium carbonate whiskers in the field of lubricating grease, especially complex calcium sulfonate lubricating grease, is rarely studied

Abstract

The invention relates to a complex calcium sulphonate lubricating grease compound and a preparation method thereof. The raw material formula of the compound comprises the following raw materials in percentage by weight: 20 to 50 percent of high-base value calcium sulphonate, 5 to 30 percent of calcium carbonate whiskers, 1 to 5 percent of glacial acetic acid, 0.05 to 0.3 percent of a titanate coupling agent, 0.5 to 3 percent of long-chain fatty acid, 2 to 5 percent of water and the balance of base oil. The preparation method comprises the following steps: (1) mixing and reacting the titanate coupling agent, part base oil and the long-chain fatty acid, adding the long-chain fatty acid, and continuing reacting; (2) mixing and heating the base oil with remaining formula amount and the high-base value calcium sulphonate, adding the water and the glacial acetic acid in sequence, and stirring continuously; (3) mixing the materials in the step (1) and the step (2), and performing dewatering reaction; (4) cooling, reducing temperature, grinding, homogenizing and performing a degassing reaction. Compared with the prior art, the comprehensive performance of the lubricating grease disclosed by the invention is remarkably improved; saponifying and high-temperature refining steps can be omitted when the complex calcium sulphonate lubricating grease compound is prepared; energy consumption and raw material cost is low; industrial popularization is benefited.

Description

technical field [0001] The invention relates to a compound calcium sulfonate lubricating grease and a preparation method thereof. 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 It is one of the most promising and widely used lubricating greases for various harsh and harsh environments such as automobiles, steel, mining, and papermaking, such as high temperature, heavy load, and water. [0003] The preparation process of composite calcium sulfonate grease is the process of converting Newtonian high-alkaline calcium sulfonate into non-Newtonian calcium sulfonate, and amorphous calcium carbonate into calcite crystal calcium carbonate, in which calcite crystal calcium carbonate is The comprehensive performance of the product has a gr...
