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 discloses an industrial grease antioxidant additive, comprising the following ingredients: 44-47 wt% of dialkyl dithiocarbamic acid dithiocarbamic acid metal salt, 3-5 wt% of ammonium sulphonate, 3-5 wt% of bis(salicylidene) propane diamine, 4-6 wt% of phosphorodithioate, 3-6 wt% of dialkyl dithiophosphate antimony, 3-5 wt% of calcium phosphate, 3-5 wt% of polyisobutylene, 2-3 wt% of styrene butylene segmented copolymer, and the balance of base oil. The preparation method of the industrial grease antioxidant additive has the advantages of simple preparation, utility, economy, and low cost, and the industrial grease antioxidant additive disclosed herein can greatly increase the oxidative stability of common grease, and can simultaneously increase various properties of the grease and prolong the life cycle, has no damage to mechanical equipments, and can comprehensively increase various effects of the grease.

Description

(1) Technical field [0001] The invention relates to a lubricating grease additive, in particular to a preparation scheme and a preparation method of an industrial lubricating grease anti-oxidation additive. (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 the current grease productio...
