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

Embodiment 1

[0010] An antioxidant additive for lubricating grease, which is composed of base oil; phenothiazine; fatty amine; disalicylidene propylenediamine; chlorinated paraffin; calcium carbonate; polyisobutylene; polyethylene. The base oil is a combination of 32# and 68# of mineral oil and soybean oil of vegetable oil, and the weight ratio of the three components is 1:1:1. The weight percent of each component is: base oil 40%; phenothiazine 42%; fatty amine 3%; disalicylidene propylenediamine 3%; chlorinated paraffin 4%; calcium carbonate 3%; ; Polyethylene 2%. Mix the above base oil; phenothiazine; fatty amine; disalicylidene propylenediamine; chlorinated paraffin; calcium carbonate; polyisobutylene; polyethylene; Stir for 120 minutes to obtain the product.

[0011] Add this product to ordinary lubricating grease according to 5% dosage, after testing and using, the following results are obtained:

[0012] 1. The anti-oxidation performance is increased by more than 2.5 times.

Embodiment 2

[0017] An antioxidant additive for lubricating grease, which is composed of base oil; phenothiazine; fatty amine; disalicylidene propylenediamine; chlorinated paraffin; calcium carbonate; polyisobutylene; polyethylene. The base oil is a combination of 5 centistokes of mineral oil and rapeseed oil of vegetable oil, and the weight ratio of the two components is 2:1. The weight percent of each component is: base oil 23%; phenothiazine 46%; fatty amine 5%; disalicylidene propylenediamine 5%; chlorinated paraffin 7%; calcium carbonate 6%; ; Polyethylene 3%. Mix the above base oil; phenothiazine; fatty amine; disalicylidene propylenediamine; chlorinated paraffin; calcium carbonate; polyisobutylene; polyethylene; Stir for 180 minutes to obtain the product.

[0018] Add this product to ordinary lubricating grease according to 5% dosage, after testing and using, the following results are obtained:

[0019] 1. The anti-oxidation performance is increased by more than 2.7 times.

Abstract

The invention relates to an antioxidant additive for lubricating grease, which is basically characterized by comprising the following components in percentage by weight: 44%-46% of phenothiazine, 3%-5% of fatty amine, 3%-5% of bis(2-hydroxybenzylidene) propanediamine, 5%-7% of chlorcosane, 4%-6% of calcium carbonate, 3%-5% of polyisobutene, 2%-3% of polyethylene, and the balance of base oil. A preparation method is easy, economic, and practical and has low cost, can ensure that the antioxidation capability of the common lubricating grease is greatly enhanced and the various properties of the lubricating grease are improved and the life cycle is prolonged; and in addition, the invention does not have any harm on mechanical equipment and totally enhances the various effects of the lubricating grease.

Description

(1) Technical field [0001] The invention relates to a lubricating grease additive, in particular to a preparation method and technical field of an antioxidant additive of 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 the current grease production, human beings ...
