Abstract

The invention discloses a metal-organic frame corrosion inhibitor hydrogel composite material and application thereof. According to the metal-organic frame corrosion inhibitor hydrogel composite material, europium-ion functional gallium-based metal-organic frame material Eu<3+>@MIL-124(Ga) loads a corrosion inhibitor and is packaged by a temperature-sensitive type hydrogel to form a reusable corrosion inhibitor hydrogel composite. According to the corrosion inhibitor hydrogel composite, the corrosion inhibitor is released through the window opening effect for targeted repair of corrosion sites, after the corrosion inhibitor film formation protaction, the temperature-sensitive type hydrogel can be easily peeled through phase separation, MOF and temperature-sensitive hydrogel are recovered,the role of "flaw-detection-type band-aid" for the corrosion of offshore engineering steel structures is played, the use of the corrosion inhibitor hydrogel composite can realize the quantitative detection, the alert response and the protection and repair function integration of marine corrosion, and significant application value and broad market prospects are achieved.

Description

technical field

[0001] The invention relates to the technical field of marine iron and steel anticorrosion coating materials, more specifically, a metal organic framework corrosion inhibitor hydrogel composite material and its preparation method and application. Background technique

[0002] At present, my country's marine development has entered a golden age, but marine corrosion is a major problem in the process of marine development, which seriously restricts the development of my country's marine economy. The marine environment is the most corrosive natural environment. Seawater is a highly corrosive electrolyte solution that contains a large amount of salts, including sodium chloride and salts containing elements such as potassium, bromine, and iodine. Marine corrosion can cause damage to steel structures in marine engineering, shorten service life, and lead to serious economic losses and even safety accidents. The application of organic migrating corrosion inhibitor ...
