Embodiment 1

[0046] (1) Preparation of covalent organic framework materials

[0047]Accurately weigh 93 mg of 3,6-bis(5-aldehyde thiophen-2-yl)-2,5bis(2-ethylhexyl)pyrrolo[3,4-c]pyrrole-1,4(2H, 5H)-dione, add 103 mL of chloroform to dissolve. Accurately weigh 32 mg of tris(4-aminophenyl)amine, add 105 mL of methanol to dissolve, and drop into the above chloroform solution. After mixing evenly, 15 mL of glacial acetic acid was added dropwise for catalysis, and it was placed on a magnetic stirrer and stirred for 72 h to make it fully react. After the reaction, centrifuge with a high-speed centrifuge at 8000 rpm for 12 min, take out the supernatant in the centrifuge tube, add 60 mL of tetrahydrofuran to wash, and continue centrifugation. Repeat this operation 3 times, the tetrahydrofuran washing solution is nearly colorless, and then add deionized water to carry out the above operation. Remove the supernatant, and the lower sediment is the covalent organic framework material.

Description

[0001] Field of Invention [0002] The invention relates to the fields of materials, chemistry and mechanical engineering, in particular to a multifunctional nano-lubricating oil additive and a preparation method and application thereof. Background technique [0003] During the service process of equipment components, the friction and wear on the surface of the moving friction pair is the main reason for the reduction or damage of mechanical stability, which not only wastes a lot of energy, but also threatens production safety. Therefore, sufficient lubrication of key parts of machinery is an important guarantee to improve equipment stability and prolong service life. At present, with the continuous progress and development of tribology, new lubricating technologies and lubricating materials continue to emerge, but liquid lubrication, especially lubricating oil (grease), still occupies an important position in the current lubrication technology field. In lubricating oil, addi...
