Abstract

The invention relates to a lubricating grease rust inhibition additive for lubricating grease, which is basically characterized by comprising the following ingredients in percentage by weight: 50 to 56 percent of bismuth naphthenate, 3 to 5 percent of sterically hindered phenol, 3 to 5 percent of bis(salicylidene) propane diamine, 6 to 8 percent of organic phosphate, 2 to 4 percent of lead naphthenate, 3 to 4 percent of boric oxide, 3 to 5 percent of polyisobutene, 2 to 4 percent of polyethylene and the balance of basic oil. The lubricating grease rust inhibition additive has the advantages of simple manufacture method, economic and practical preparation scheme and low cost, and can ensure that the rust prevention and corrosion resistance function of the ordinary lubricating grease can be greatly improved and various integral performances of the lubricating grease can be improved while the rust prevention and anti-oxidation performance of the lubricating grease is enhanced, and the service life of the lubricating grease can be prolonged. Good protective effect can be realized on various kinds of mechanical equipment.

Description

(1) Technical field

[0001] The invention relates to a lubricating grease additive, in particular to a preparation method and a preparation scheme of a lubricating grease rust inhibiting additive for lubricating grease. (two) background technology:

[0002] The current use of grease is that it is easier to seal into bearings due to the semi-solid state of the grease, and the grease also acts as a seal against contamination in wet and dusty environments. Therefore, the use of grease is in great demand. Moreover, the use range of grease is also very wide, so various types of grease additives are required to improve the working performance of various greases, so as to meet people's requirements for the use of grease, so the additives currently used for grease are more expensive than grease additives. The use of lubricating oil additives is also large. However, the existing anti-corrosion and anti-corrosion functional additives for lubricating greases are not ideal enough, and ...
