[0018] Preparation method of long-acting corrosion inhibitor loading structure:
[0019] (1) Under the stirring condition of 200r / min, in 100 parts by mass of water, add 0.1 mol / liter of hydrochloric acid to adjust the pH value of the solution between 3; then heat the solution to 50°C, add 10 parts by mass of cerium nitrate and mix well, Then add 1 mass part of absolute ethanol and stir for 0.5 hours;
[0020] (2) Add 10 parts by mass of analytically pure diatomaceous earth to the solution in step (1) under the stirring condition of 500 r / min, and mix and stir for 3 hours at 80° C.;
[0021] (3) Centrifuge the mixture obtained in step (2), wash it with ethanol for 4 times, dry it in an oven at 80°C, take it out and grind it through a 200-mesh sieve to obtain a powder with a diatomite-loaded corrosion inhibitor structure. Put the dried powder into a high-temperature calcination furnace and heat it up to 1000°C for 1 hour, then cool it to room temperature with the furnace and t...
