Abstract

The invention discloses a deep hole nickel electroplating plating solution, a preparation method and an electroplating method, and belongs to the technical field of nickel electroplating. The problemsthat in the prior art, nickel sulfate and nickel sulfamate based plating solution can not be used for deep hole plating are solved. The deep hole nickel electroplating plating solution comprises thenickel sulfate, nickel chloride, a boric acid, a dodecylbenzene sulfonic acid, sodium citrate, an ammonium sulfate, a hydroxypropyl pavement agent and a PS reagent; and the nickel electroplating plating solution comprises 200 - 300 g/L of the nickel sulfate, 30 - 50 g/L of the nickel chloride, 30 - 50 g/L of the boric acid, 0.006 - 0.10 g/L of the dodecylbenzene sulfonic acid, 50 - 90 g/L of the sodium citrate, 5 - 20 g/L of the ammonium sulfate, 0.11 - 1.10 ml/L of the hydroxypropyl pavement agent, and 0.001 - 0.10 g/L of the PS reagent. According to the deep hole nickel electroplating plating solution, the electroplating operation of the irregular deep hole in a battery shell is realized.

Description

technical field [0001] The invention belongs to the technical field of electroplating nickel, in particular to a preparation of a deep-hole electroplating nickel plating solution and an electroplating method. Background technique [0002] The battery shell is an important part of the alkaline battery manufacturer. In order to improve its corrosion resistance and decoration, the inner and outer surfaces of the battery steel shell often need to be plated with bright nickel. However, due to the large aspect ratio, the aspect ratio is usually 3.5 to 5.0 In between, it is difficult to guarantee the coating thickness and anti-rust ability of the inner surface by general electroplating process. Although electroless plating can be used to obtain uniform coatings on the inner and outer surfaces, the nickel-phosphorus alloy coating has poor alkali corrosion resistance, easy discoloration, difficult process maintenance, short service life of the plating solution and high cost, so it ha...
