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 consists of base oil; hindered phenol; alkyl succinic acid derivatives; disalicylidene propylenediamine; alkyl phosphate ester and salt; lead naphthenate; borate metal salt; poly Composition of isobutene. The base oil is a combination of 150BS and 32# 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 35%; sterically hindered phenol 42%; alkyl succinic acid derivative 3%; disalicylidene propylenediamine 3%; Lead alkanoate 4%; Borate metal salt 3%; Polyisobutylene 4%. The above base oil; hindered phenol; alkyl succinic acid derivatives; disalicylidene propylene diamine; alkyl containing phosphate and salt; lead naphthenate; Add weight percentage measurement. Mix evenly, heat and control the temperature between 55-60°C, and stir for 120 minutes to obtain the product.

Abstract

The invention relates to a lubricating grease antioxidant additive which is basically characterized by comprising the following components in percentage by weight: 42-45 percent of sterically hindered phenol, 3-5 percent of alkylated succinic acid derivative, 3-5 percent of bisalicylpropane diamine, 6-8 percent of alkyl containing phosphate and salt, 4-6 percent of lead naphthenate, 3-5 percent of metal borates, 5-7 percent of polyisobutene and the balance of base oil. The lubricating grease antioxidant additive has the advantages of simple preparation, economy, practicability and low cost, can ensure that the oxidation resistance of common lubricating grease is greatly improved and various properties of the lubricating grease are greatly improved when the oxidation resistance of the lubricating grease is enhanced and the use period is prolonged, has no damage to mechanical equipment and comprehensively improves various effects of the lubricating 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 a lubricating grease antioxidative 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 production, human bein...
