| titleOfInvention | Preparation method of skin membrane passivation solution used before high precision iron casting coating |
| abstract | The invention discloses a preparation method of a skin membrane passivation solution used before high precision iron casting coating; the passivation solution comprises 10-12% of phytic acid, 1-2% of tartaric acid, 0.5-1.5% of citric acid, 0.5-0.7% of bromic acid, 2.5-3.5% of sodium benzoate, 0.35-0.55% of benzotriazole, 3.5-4.5% of triethanolamine, 2.3-2.7% of sodium carbonate, 0.4-0.6% of isothiaimidazolone, 1-2% of industrial alcohol, and the balance of water; the preparation method is as follows: adding water into a reaction kettle, starting a blender, stirring in 300-400 RPM / min speed, sequentially adding the tartaric acid, the citric acid, the bromic acid, the sodium benzoate, the sodium carbonate, the triethanolamine and the phytic acid, continuously stirring for 6-12min when each material is added; then using the industrial alcohol to dissolve the benzotriazole and the isothiaimidazolone, and adding the dissolved benzotriazole and isothiaimidazolone into the reaction kettle, and continuously stirring for 30-40 minutes. |
