Abstract

The invention discloses a single dye type bright acidic copper plating additive and a preparation method and application thereof. The additive is prepared from a polymeric phenazine dye, a triphenylmethane dye, a thiazine dye, a surfactant and polysulfide serving as main raw materials; when the additive is applied to copper plating solution for copper plating, the using effect can reach that of a three-dose additive; the entire plated sheet is bright; the additive is simple to manage and the maladjustment of the plating solution additive is not caused; and even if the concentration of the additive is over-high, the plating solution can be continuously used after the plating solution is slightly diluted.

Description

technical field

[0001] The invention relates to a copper plating additive, in particular to a single-dose dye type bright acidic copper plating additive. Background technique

[0002] Due to the good toughness of the coating, the plating solution has good bright leveling and fast deposition speed. It is used in plastic electroplating, metal copper-nickel-chromium decorative electroplating, metallization electroplating of printing plate holes and electroforming. occupies an important position.

[0003] Research on acidic copper plating additives by major companies around the world began in the 1950s, and foreign research has successfully added sulfur- and nitrogen-containing compounds, such as thiourea and its derivatives, 2-mercaptobenzothiazole, 2-mercaptobenzothiazole Some dyes such as imidazole and basic saffron, thiazapine, triphenylmethane, etc., may have a brighter coating; in the 1960s, some additives such as polyether were added to make the brightness, leveling abil...
