[0041] A kind of preparation method of sodium hypochlorite generator electrode, comprises the following steps:
[0042] 1) Use a titanium plate with a titanium content of 99.9% and a thickness of 1 mm as the substrate. After the titanium plate is sandblasted and polished to remove the oxide layer, it is placed in a NaOH solution with a concentration of 10% and shaken for 30 minutes, and then the oxalic acid solution with a concentration of 20% is used. Etch the titanium plate for 2 hours, wash it and place it in an ethanol solution for use;
[0043] 2) Preparation of active coating solution for the inner layer: use a mixed solution of n-butanol and isopropanol as a solvent, the volume ratio of n-butanol and isopropanol is 2:1, use ruthenium trichloride, chloroiridic acid, titanic acid Tetrabutyl ester and oxygen evolution inhibitor are used as solute, and concentrated hydrochloric acid is used as a stabilizer to form an inner layer active coating solution; the metal ion concen...
