Abstract

The invention discloses a high-speed tinning solution and a preparation method thereof. Deionized water is added to a clean beaker until the volume of the water accounts for 1/2 that of the beaker; a required amount of methanesulfonic acid is measured through a measuring cylinder and put in the beaker, and the mixture is stirred uniformly; a required amount of tin methanesulfonate is measured through the measuring cylinder and put in the beaker, and the mixture is stirred uniformly; additives with the concentration being 60-100 ml/L are added to a tin methanesulfonate solution and stirred uniformly; the deionized water is added until the mixture is in a predetermined volume, and the high-speed tinning solution is prepared. Plating with uniform color and consistent crystal grains is obtained in a wider current density range, formation of tin whisker is effectively controlled, the anti-tarnishing capability and the excellent weldable performance of the plating are guaranteed, the current density can be increased to the greatest extent, the anti-tarnishing capability and the weldable performance are guaranteed, meanwhile, a defoaming agent is not used, and fewer organic impurities are mixed in the plating.

Description

technical field [0001] The invention belongs to the technical field of electroplating, and in particular relates to a high-speed tin plating solution and a preparation method thereof. Background technique [0002] Tin coating has good stability, strong corrosion resistance and discoloration resistance, non-toxic, soft coating, good solderability and ductility, so it is widely used in industry. Tin plating on steel or copper substrates is a cathodic coating. The thin tin layer has a good protective effect on the substrate and is non-toxic. Therefore, tin plating is often used in the production of steel strips and the canning industry. Early tin plating often used hot-dipping process. This production method consumes more energy. Not only is it difficult to obtain a uniform and smooth coating, but it is also easy to cause tin waste. People have successfully studied alkaline tin plating and neutral plating. Tin and acid tin plating are used stably in production practice. [00...
