Abstract
The invention relates to a galvanizing chromium-free iridescent passivation agent. The galvanizing chromium-free iridescent passivation agent is prepared by dissolving and uniformly mixing sodium molybdate, sodium citrate, sodium phosphate, tannic acid, hydroxyethylidene diphosphonic acid, cobalt nitrate and other materials in a certain proportion. The galvanizing chromium-free iridescent passivation agent can remarkably improve the corrosion resisting property of a coating, and simultaneously, the iridescent passivation agent has bright color.
Description
Technical field
The present invention relates to a kind of zinc-plated Chrome-free color passivating agent, relate in particular to a kind of composition of zinc-plated Chrome-free color passivating agent, the effect and the compound method of each composition.
Background technology
According to GB-2008 " plating pollutant emission standard ", to Pd, Hg, Cd, Cr
6+, 6 kinds of first kind pollutents such as poly-dibromodiphenyl ether and poly-bromo biphenyl emission standard lower restriction has been arranged, European Union in " about in electronic electric equipment, banning use of the instruction of some objectionable impuritiess " of enforcement on July 1 in 2006 (ROHS), forbid containing 6 kinds of objectionable impuritiess such as sexavalent chrome in the electronics thrown on the European Union market and the electrical equipment, so the products substitution sexavalent chrome passivation of environment-friendly type becomes an urgent demand.
Trivalent chromium and chromium-free deactivation both direction are mainly adopted in the passivation of environment-friendly type.The chromium-free deactivation system has titanate, molybdate, tungstate, rare earth, silicate, present these Chrome-free system passive film asepsis environment-protectings, solidity to corrosion and outward appearance all improve a lot in recent years, satisfied common handware and electroplated requirement, so non-chromium inactivating technique has wide practical use industrial.
Summary of the invention
The present invention makes simultaneously and does not contain Cr in the passivating solution in order to improve zinc coating passivation film asepsis environment-protecting
6+, Cr
3+And invented a kind of zinc-plated Chrome-free color passivating agent.
The present invention adopts article such as Sodium orthomolybdate, Trisodium Citrate, sodium phosphate, tannic acid, hydroxy ethylene diphosphonic acid, Xiao Suangu to form zinc-plated Chrome-free color passivating agent.
Concrete preparation method of the present invention comprises the step of following order:
A. the Trisodium Citrate of calculated amount is poured in the less water, stirring is fully dissolved it;
B. Sodium orthomolybdate and the sodium phosphate with calculated amount slowly adds, and stirs it is fully dissolved;
C. the tannic acid of calculated amount is poured into, stirred;
D. the hydroxy ethylene diphosphonic acid of calculated amount is poured into, stirred;
E. the Xiao Suangu with calculated amount slowly adds, and stirs rapidly, and it is fully dissolved;
F. behind the water constant volume with calculated amount, left standstill 10 minutes, transfer pH in 1～2 scope with nitric acid.
A kind of zinc-plated Chrome-free color passivating agent of gained of the present invention is for clarification is dark-brown liquid.
Description of test
The present invention by zinc-plated experiment after, in the Chrome-free color passivation solution, implement Passivation Treatment, through after the processing of different time, observe the color and luster of coating, and carry out neutral salt spray test and measure its corrosion resisting property.
Embodiment
The concrete preparation process of present embodiment is as follows:
A. prepare general low-cyanide zinc plating solution, and adjust the pH value, electroplate.
B. take out sample behind the certain hour, carry out Passivation Treatment after the bright dipping in 3% nitric acid, passivation time is 8～20s.
C. observe the color and luster that transforms rete, and carry out neutral salt spray test.
A kind of zinc-plated Chrome-free color passivating agent technological specification is: Sodium orthomolybdate, Trisodium Citrate, sodium phosphate, tannic acid, hydroxy ethylene diphosphonic acid, Xiao Suangu
Annotate: when stirring, passivation time can shorten.
Claims (1)
1. zinc-plated Chrome-free color passivating agent, the raw material that it is characterized in that passivator is composed as follows: contain Sodium orthomolybdate 10～40g/L, Trisodium Citrate 10～20g/L, sodium phosphate 10～30g/L, tannic acid 5～15g/L, hydroxy ethylene diphosphonic acid 10～20ml/L, Xiao Suangu 5～15g/L, all the other are water; The pH value maintained in 1～2 scope when Chrome-free color passivating agent used.
