The nickel plating brightener prepared by the method of the invention has good nickel plating effect.

Description

technical field [0001] The invention relates to the technical field of nickel plating brightener, in particular to a nickel plating brightener and a preparation method thereof. Background technique [0002] The main function of the brightener is to remove the oil, oxidized and unoxidized surface impurities staying on the metal surface through the active surface, and to maintain the cleanliness, gloss and color fastness of the outside of the object. The texture of the appearance is affected by the grinding effect, and the efficiency of polishing is improved. [0003] Chinese patent CN102766890A discloses an acid copper brightener. The acid copper brightener raw materials are distilled water, copper plating brightener, sodium polydithiodipropane sulfonate and polyethylene glycol, and the copper plating brightener is 2-thio Benzimidazole and Thiourea. The weight ratio of the distilled water, thiourea, 2-thiobenzimidazole, sodium polydithiodipropanesulfonate and polyethylene g...
