Special chemical nickel activating agent for ceramic-based circuit board and preparation method of special chemical nickel activating agent

The invention relates to the technical field of chemical nickel plating surface treatment, in particular to a special chemical nickel activating agent for a ceramic-based circuit board and a preparation method of the special chemical nickel activating agent. The chemical nickel activating agent is prepared from the following raw material components: 0.1 to 0.2 g/L of tetraammonium dichloride, 0.4 to 0.6 g/L of sulfur-containing surfactant, 1 to 8 ppm of initial initiator, 0.5 to 10 g/L of anti-impurity agent, 1 to 10 g/L of complexing agent, 20 to 50 mL/L of hydrochloric acid and the balance of pure water. By optimizing the proportion, the obtained chemical nickel plating activating agent is moderate in palladium ion concentration, during use, the reaction initial speed is high, palladium is basically not decomposed or adsorbed, the service life of the activating agent is greatly prolonged, and meanwhile the composite surface active agent is high in activating efficiency, few in foam, easy to clean and suitab
