Abstract

The invention discloses a high-corrosion-resistance zinc-plating brightener and a preparation method thereof. The high-corrosion-resistance zinc-plating brightener is prepared from the following ingredients in parts by weight: 25-35 parts of anionic surfactant, 10-15 parts of nonionic surfactant, 1-2 parts of benzotriazole, 4-8 parts of NNF, 10-15 parts of sensitizer and 25-50 parts of water. The high-corrosion-resistance zinc-plating brightener and the preparation method thereof have the beneficial effects that the brightness of a zinc coating of metal is improved, and meanwhile, the high-corrosion-resistance zinc-plating brightener can be used for improving the corrosion resistance of the zinc coating, reducing oxidated white spots and prolonging the hold time of surface brightness of the zinc coating.

Description

technical field [0001] The invention relates to a brightener, in particular to a high-corrosion-resistant galvanized 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. [0003] The Chinese patent with publication number CN103184479A discloses a galvanized composite brightener and a preparation method thereof. The brightener can significantly expand the brightness of the current density area, the high current density area is free from burning, and the low current density area is fully bright. [0004] During use, the surface of the metal galvanized layer will be oxidized, resulting in white spots, which will affect the aesthetics of the galvanized layer. Therefore, people hope that the brightener can not only...
