| titleOfInvention | Preparation method of zinc alloy blackening treatment liquid for lamps |
| abstract | The present invention discloses a preparation method of a zinc alloy blackening treatment liquid for lamps. The treatment liquid adopted by the process comprises, by weight, 6-8% of oxalic acid, 7-9% of citric acid, 5-7% of 85% phosphoric acid, 6-8% of sodium chloride, 2-4% of trisodium phosphate, 12-14% of potassium peroxide, 2.5-3.5% of sodium pyrophosphate, 1.0-2.0% of 8-hydroxyquinoline, 11-13% of copper sulfate, 0.5-1.5% of carotene, and the balance of water. The preparation method comprises: taking an appropriate amount of water to dissolve oxalic acid, citric acid and phosphoric acid to prepare a mixed acid solution, taking an appropriate amount of water, sequentially adding sodium chloride, trisodium phosphate, potassium peroxide, sodium pyrophosphate, 8-hydroxyquinoline, copper sulfate and carotene, stirring for 12-16 min to make it uniform, adding the mixed acid solution to the obtained solution, adding the balance of water, and then stirring for 8-10 min. |
