Problems solved by technology

However, the anti-oxidation function of the existing lubricating grease is not ideal. While resisting oxidation, it cannot fully protect mechanical equipment
Because in the current grease production, human beings pay more attention to: greases in light load and high-speed applications rely on strong hydrodynamic lubrication, and only pay attention to anti-rust, anti-oxidation and anti-wear additives in the grease , so that the overall function of the grease has been affected to a certain extent

Abstract

The invention relates to a special lubricating grease antioxidant additive for lubricating grease. The additive is characterized by comprising the following components in percentage by weight: 44-48 percent of ashless dialkyldithio carbamic acid ester, 3-5 percent of bismuth naphthenate, 3-5 percent of disalicyl propane diamine, 6-8 percent of phosphate ester, 3-4 percent of lead naphthenate, 3-4 percent of chlorinated paraffin, 3-5 percent of calcium acetate, 1-2 percent of polyethylene and the balance of base oil. The invention has the advantages of simple preparation method, economy, practicality and low cost, greatly improves the oxidation resistance of ordinary lubricating grease, improves various properties of the lubricating grease while improving the oxidation resistance of the lubricating grease, prolongs the life cycle, has no damages to equipment and comprehensively improves various effects of the lubricating grease.

Description

(1) Technical field [0001] The invention relates to an additive for lubricating grease, in particular to a preparation scheme and a preparation method of a lubricating grease anti-oxidant additive specially used for lubricating grease. (two) background technology: [0002] Grease is currently used because of its specific semi-solid state, grease seals into bearings more easily than oil, and grease also acts as a seal against contamination in wet and dusty environments. Therefore, the use of lubricating grease is in great demand. The use of grease is very wide because of its wide range, so various types of grease additives are required to be used in grease. In order to meet people's requirements for the use of grease, the amount of grease additives used is larger than that of lubricating oil additives. However, the anti-oxidation function of the existing lubricating grease is not ideal, and the mechanical equipment cannot be fully protected while anti-oxidation. Because in...
