Abstract
An electroplating additive solution, a preparation method thereof, and a hard silver-graphene electroplating mixture liquid are provided. The electroplating additive solution includes metal oxide, glycerol, alkali metal hydroxide and water. The metal oxide, the glycerol, the alkali metal hydroxide and the water have a mass ratio of 1:(1-3):(3-6):(8-15). When the electroplating additive of the present disclosure is used in an electroplating mixture liquid, it can increase the hardness of the finally formed plating layer.
