Preparation method of functional corrosion inhibitor for preventing deicing salt corrosion of pavement concrete
A preparation method of a functional corrosion inhibitor for preventing deicing salt corrosion of pavement concrete belongs to the technical field of pavement concrete corrosion inhibitors, and comprises the following steps: performing high-temperature space modification on original layered double hydroxides to obtain layered double oxides as a matrix, adding the layered double oxides into an organic corrosion inhibition ion solution for full reaction, and performing centrifugal washing and suction filtration to obtain the functional corrosion inhibitor for preventing deicing salt corrosion of pavement concrete. And drying a reactant obtained by centrifugation, and grinding to obtain the novel organic corrosion inhibition ion modified layered double hydroxide corrosion inhibitor. Organic corrosion inhibition ions are used for carrying out interlayer modification on original layered double hydroxides to obtain the green and environment-friendly functionalized novel corrosion inhibitor, the corrosion inhibitor has the dual inhibition effects of curing corrosive ions such as chloride ions and releasing the organic corrosion inhibition ions, and meanwhile, the physical blocking effect of concrete is improved; the anti-corrosion agent is used for inhibiting corrosion to the pavement in a deicing salt environment in winter, effectively improving the anti-corrosion performance of the pavement and prolonging the service life of the pavement, and is easy to popularize and industrialize and wide in application prospect.
