Embodiment 1

[0045] A highly active organic molybdenum compound, the general chemical formula (1) of the organic molybdenum compound is as follows:

[0046] In this general formula, molybdenum "Mo" is used as the nucleophilic center, and "Mo" is grafted with two "S=CS-" groups, so that the molecular structure of the invention product has both "-S-Mo-S- ", and the feature of "-S=S-Mo-S=C-S-"; "Mo" has the structure and characteristics similar to "molybdenum disulfide" in the molecular structure of the invented product; each of R1 and R2 is grafted An alkyl diamine is added, that is, R1 and R2 in the molecular structure of the invention product contain two diamines respectively, that is to say: there are a total of 4 amine groups in the molecular structure of the product; a total of 2 "S" are grafted in the molecular structure of the product =CS-S-" group, so that there are two "S=CS-" groups in the molecular structure of the product, which can be simplified as two SCSs in the molecular stru...

Embodiment 2

[0068] The principle of the second embodiment is basically the same as that of the first embodiment, except that the substance is different, which is a highly active organic molybdenum compound. The general chemical formula (2) of the organic molybdenum compound is as follows:

[0069] In this general formula, molybdenum "Mo" is used as the nucleophilic center, and "Mo" is grafted with two "S=CS-" groups, so that the molecular structure of the invention product has both "-S-Mo-S- ", and the feature of "-S=S-Mo-S=C-S-"; "Mo" has the structure and characteristics similar to "molybdenum disulfide" in the molecular structure of the invented product; each of R1 and R2 is grafted Two amine groups are added, that is, R1 and R2 in the molecular structure of the inventive product contain two diamines respectively, and there are a total of 4 amine groups in the molecular structure of the product; a total of 2 "S=C-S-" are grafted in the molecular structure of the product " group, so tha...

Embodiment 3

[0091] The principle of the third embodiment is basically the same as that of the first embodiment, except that the substance is different, which is a highly active organic molybdenum compound. The general chemical formula (1) of the organic molybdenum compound is as follows:

[0092] In this general formula, molybdenum "Mo" is used as the nucleophilic center, and "Mo" is grafted with two "S=CS-" groups, so that the molecular structure of the invention product has both "-S-Mo-S- ", and the feature of "-S=S-Mo-S=C-S-"; "Mo" has the structure and characteristics similar to "molybdenum disulfide" in the molecular structure of the invented product; each of R1 and R2 is grafted Two amine groups have been added, that is, there are a total of 4 amine groups in the molecular structure of the inventive product; a total of 2 "S=CS-" groups have been grafted in the molecular structure of the product, so that there are 2 "S=CS-" groups in the molecular structure of the product. The S=CS-"...

Abstract

The invention relates to a high-activity organic molybdenum compound and a preparation and application method thereof. The general chemical formula of the organic molybdenum compound is as shown in the general formula (1), wherein Mo is used as the nucleophilic center and grafted with two S=C-S- groups to allow the molecular structure of the organic molybdenum compound to have the features of -S-Mo-S- and the features of -S=S-Mo-S=C-S-; Mo has the structural form and features similar to molybdenum disulfide in the molecular structure of the organic molybdenum compound; R1 is grafted with alkyl diamine, R2 is grafted with alkyl diamine, that is to say, R1 and R2 in the molecular structure of the organic molybdenum compound respectively contain 2 diamines, and the molecular structure of the organic molybdenum compound contains 4 amino groups. Two S=C-S- groups are grafted in the molecular structure of the organic molybdenum compound, so that the molecular structure of the organic molybdenum compound contains two SCS (simplified form) groups or two groups similar to SCS (for short).

Description

technical field [0001] The invention relates to a new organic molybdenum compound and its preparation and use method, especially the lubricating composition containing the compound in its preparation and use as a friction modifier. It belongs to the technical field of new materials. Background technique: [0002] Organic molybdenum is a general term for oil-soluble organic molybdenum compounds such as oxymolybdenum dialkyldithiophosphate, molybdenum dialkyldithiocarbamate, molybdenum amine complex, molybdenum naphthenate, and molybdenum alkyl salicylate. [0003] At present, organic molybdenum mainly includes oxymolybdenum dialkyldithiophosphate, nitrogen-containing molybdenum dialkyldithiophosphate, molybdenum dialkyldithiocarbamate, molybdenum amine complex, molybdenum naphthenate, alkyl Molybdenum salicylate. [0004] The lubrication and friction reduction mechanism of organic molybdenum is mainly related to the polished surface of the friction pair. On the surface of t...
