Problems solved by technology

[0005] "Science" discloses that the longer the carbon chain, the more fluorine atoms, the better the hydrophobicity. However, in the prior art, the fluorine-containing anti-corrosion and anti-fingerprint materials are all alkoxysilanes containing short fluorocarbon chains, and the hydrophobicity is relatively high.

Abstract

The invention discloses a two-component self-assembly functional anticorrosion agent and a preparation method thereof. Under the protection of nitrogen, react perfluoroalkylpropenyl halides and absolute ethanol under the action of a catalyst at room temperature for 12 hours, filter, reduce Unreacted ethanol was removed by pressure distillation to obtain perfluoroalkyl ether ethyl ester monomer; under nitrogen protection, two different perfluoroalkyl ether ethyl ester monomers were mixed with aminopropyltriethoxysilane, and added Alkaline solvent, stirred at room temperature for 24 hours, filtered, evaporated under reduced pressure to remove the solvent, and then separated on a silica gel column with an eluent to obtain a pure liquid of a two-component self-assembling functional anti-corrosion agent. The invention can form alkoxysilane containing polyfluorine long carbon chain, so that the chemical temperature performance, friction resistance and hydrophobicity and oleophobicity are better.

Description

Technical field [0001] The invention relates to the technical field of surface treatment, in particular to a two-component self-assembly functional anticorrosion agent and a preparation method thereof. Background technique [0002] When the surface of products such as mobile phones, tablets, and sanitary ware are contaminated by sweat or sebum, it will not only affect the appearance of the product, but also affect the performance of the product. If it is not processed for a long time, it will cause a certain degree of corrosion on the surface of the product. Therefore, the surface of the product needs to be treated to solve the problems of easy corrosion and easy contamination. [0003] Fluoropolymer has comprehensive properties such as high thermal stability, chemical inertness, weather resistance, low friction coefficient, low refractive index, low surface energy, excellent water and oil repellency, radiation resistance and aging resistance, and is widely used in petroleum Chemi...
