Abstract
The invention discloses a black passivating agent. The black passivating agent comprises the following raw materials and components in parts by weight in a formula: 2-3 parts of disodium hydrogen phosphate, 3-4 parts of boric acid, 3-4 parts of phosphoric acid, 2-3 parts of sodium benzoate, 2-3 parts of sodium tripolyphosphate, 1-2 parts of sodium pyrophosphate, 2-3 parts of adipic acid, 2-3 parts of dimethyl malonate, 3-5 parts of copper carbonate, 3-5 parts of copper nitrate, 3-5 parts of copper chloride, 2-3 parts of sodium hyposulfite, 2-3 parts of sodium hydrogen sulfite, 3-4 parts of sodium dodecyl sulfate, 3-4 parts of cetyltrimethylammonium chloride, 2-3 parts of dodecyl dimethyl benzyl ammonium chloride, and 20-30 parts of activated carbon. According to the black passivating agent, during passivation, and after the processing of different times, the color of a plating coat is observed, and a neutral salt spray test is performed so as to test a corrosion resisting property; the black passivating agent can enhance the hardness of a plated membrane of a zinc-plated layer, and is free from toxicity, environmentally-friendly and uniform in plating.
Description
Technical field
The present invention relates to the technical field of passivator, particularly relate to a kind of black passivator.
Background technology
Electro-galvanizing is one of important measures of anti-corrosion of metal, and the pollution of electroplating industry is mainly derived from the Passivation Treatment after plating, and what mainly adopt Passivation Technology for Zinc Coating on the market at present is the passivation of sexavalence chromic salts and chromic salt passivation! The cr ion contained in traditional chromium hydrochlorate passivating solution has toxicity, and environmental pollution is serious, and it is applied in and is subject to strict restriction both at home and abroad.So far, also do not have the passivation technology of complete Chrome-free can substitute the passivation of traditional chromium hydrochlorate both at home and abroad, realize suitability for industrialized production.Wherein chromic salt passive film can not show a candle to sexavalence chromic salts in corrosion resisting property, and chromic salt passive film can be converted into sexavalent chrome in the process of placing, and causes film ten content of 6-valence Cr ions exceed standard and make the circulation of product be subject to the large restriction of rubbish.Gu this research has well ornamental and corrosion resisting property good, low stain or pollution-free, fundamentally solve the passivation technology of chromic salts passivation Problems existing, European Union's green technology index is broken through to electroplating industry, promotes environmentally friendly production significant.
Summary of the invention
The object of the invention is the shortcoming in order to overcome above-mentioned prior art, a kind of black passivator is provided, this black passivator is in Passivation Treatment, after the process of different time, observe the color and luster of coating, and carry out neutral salt spray test and measure its corrosion resisting property, there is the hardness improving zinc coating platingization film, asepsis environment-protecting, coating is even.
The technical solution adopted for the present invention to solve the technical problems is: a kind of black passivator, be made up of the composition of raw materials component of following mass percent: 2-3 part Sodium phosphate dibasic, 3-4 part boric acid, 3-4 part phosphoric acid, 2-3 part Sodium Benzoate, 2-3 part tripoly phosphate sodium STPP, 1-2 part trisodium phosphate, 2-3 part hexanodioic acid, 2-3 part dimethyl malonate, 3-5 part copper carbonate, 3-5 part cupric nitrate, 3-5 part cupric chloride, 2-3 part V-Brite B, 2-3 part sodium bisulfite, 3-4 part sodium lauryl sulphate, 3-4 part palmityl trimethyl ammonium chloride, 2-3 part dodecyl benzyl dimethyl ammonium chloride, 20-30 part gac.
Further, 2 parts of Sodium phosphate dibasics, 3 parts of boric acid, 3 parts of phosphoric acid, 2 parts of Sodium Benzoates, 2 parts of tripoly phosphate sodium STPPs, 1 part of trisodium phosphate, 2 parts of hexanodioic acids, 2 parts of dimethyl malonates, 3 parts of copper carbonates, 3 parts of cupric nitrates, 3 parts of cupric chlorides, 2 parts of V-Brite Bs, 2 parts of sodium bisulfites, 3 parts of sodium lauryl sulphate, 3 parts of palmityl trimethyl ammonium chlorides, 2 parts of dodecyl benzyl dimethyl ammonium chlorides, 20 parts of gacs are comprised.
Or, comprise 3 parts of Sodium phosphate dibasics, 4 parts of boric acid, 4 parts of phosphoric acid, 3 parts of Sodium Benzoates, 3 parts of tripoly phosphate sodium STPPs, 2 parts of trisodium phosphates, 3 parts of hexanodioic acids, 3 parts of dimethyl malonates, 5 parts of copper carbonates, 5 parts of cupric nitrates, 5 parts of cupric chlorides, 3 parts of V-Brite Bs, 3 parts of sodium bisulfites, 4 parts of sodium lauryl sulphate, 4 parts of palmityl trimethyl ammonium chlorides, 3 parts of dodecyl benzyl dimethyl ammonium chlorides, 30 parts of gacs.
In sum, the invention has the beneficial effects as follows: black passivator of the present invention in Passivation Treatment, after the process of different time, observe the color and luster of coating, and carry out neutral salt spray test and measure its corrosion resisting property, there is the hardness improving zinc coating platingization film, asepsis environment-protecting, coating is even.
