| titleOfInvention | Preparation method of activation solution for aluminum alloy electroplating pretreatment |
| abstract | 4The invention discloses a preparation method of an activation solution for aluminum alloy electroplating pretreatment. The preparation method comprises the following steps: respectively adding 1/3 of water with the temperature of above 35-45DEG C into a first tank and a second tank, dissolving 45-55g/L of phosphoric acid in the first tank, dissolving 12-14g/L of potassium tetraborate in the second tank, and uniformly stirring; sequentially adding 23-27g/L of potassium pyrophosphate, 34-38g/L parts of acetic acid, 13-15g/L of potassium fluoride, 6-8g/L of potassium carbonate, 7-9g/L of ammonium sulfate, 32-36g/L of sodium phosphate and 6-8g/L of ammonium hydrogen fluoride into the first tank, stirring for 5-15min after complete dissolving; pouring the solution in the second tank into the solution in the first tank under stirring, and stirring until the above two solutions are uniformly mixed; and adding 0.5-1.5g/L of thiourea, and adding water to a calculated volume in order to obtain the activation solution. |
