Preparation method of multifunctional reinforced concrete corrosion inhibitor
The invention discloses a preparation method of a multifunctional reinforced concrete corrosion inhibitor and relates to a reinforced concrete corrosion inhibitor. The preparation method comprises the steps that 1, layered double hydroxide is used as a precursor to perform calcination; 2, a calcination product obtained through the step 1 is arranged in a sodium hydroxide solution, and stirring, filtration and washing are performed to obtain a filtration product 1; 3, the filtration product 1 is arranged in a potassium hydrogen phthalate solution, and stirring, filtration and washing are performed to obtain a filtration product 2; 4, the filtration product 2 is dried and then is grinded into powder, namely the multifunctional reinforced concrete corrosion inhibitor is obtained. A modification and calcination reforming method is utilized to load various corrosion inhibitor ions in a layered structure of the double hydroxide so as to obtain the multifunctional reinforced concrete corrosion inhibitor, the multifunctional reinforced concrete corrosion inhibitor is used in a concrete structure, can simultaneously reduce the chloride ion concentration in concrete, release the corrosion inhibitor ions, keep the high pH value of the concrete and improve the concrete compactness, has excellent comprehensive anti-corrosion performance for the reinforced concrete structure and can provide multiple effective protection for steel bars embedded in the concrete.
