Abstract
The invention relates to an olive passivator with trivalent chromium of a Bundy tube, which is formed by dissolving and uniformly mixing up ingredients of chromic chloride, malonic acid, sodium citrate, cupric sulfate, sodium sulfite, sodium dodecyl sulfate and the like according to a certain proportion, passivating and then carrying out sealing treatment with sealing agent, the corrosion resisting property of a plating layer is obviously increased by the olive passivator with trivalent chromium of the Bundy tube, and the environmental pollution is reduced.
Description
Technical field
The present invention relates to Bandaid pipe trivalent chromium green black colour passivator, relate in particular to the composition and the compound method of trivalent chromium green black colour passivator.
Background technology
The Bandaid pipe just is meant the fine steel tube of diameter at 4.6-10.6mm.Be mainly used in oil-pressure gauge(feed)pipe, oil fuel pipe, brake line and similar device in automotive industry, refrigeration industry, the well heater process industry; Can also be widely used in alternative copper pipe; Reduce use cost; The Bandaid pipe is with cold rolled strip thin plate pipe crimping, welding, zinc-plated completion, and since its wear and corrosion behavior is had relatively high expectations, so generally all adopt the green black colour passivation to satisfy its requirement.Traditional green black colour passivation technology all is to adopt the sexavalent chrome passivation, but sexavalent chrome has severe toxicity, has the effect of carcinogenic teratogenesis.European Union (ROHs), forbids throwing on the European Union market Pd, Hg, Cd, Cr in " about in electronic electric equipment, banning use of some objectionable impurities instruction " of enforcement on July 1 in 2006
6+, gather dibromodiphenyl ether and gather 6 kinds of objectionable impuritiess such as bromo biphenyl.On March 1st, 2007 rose, and China forbids that the electric equipment products strict demand that puts goods on the market can not contain above 6 kinds of objectionable impuritiess.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; Though present these Chrome-free system asepsis environment-protectings; But solidity to corrosion and outward appearance do not have the good of sexavalent chrome passivation; Satisfied not common handware and electroplated requirement, said nothing of and satisfy the requirement of high anti-corrosion ability, so the not widespread use in industry of the technology of chromium-free deactivation.Therefore, the technology of non-hexavalent chromium passivation mainly is based on the research and development of trivalent chromium passivation technique.
Summary of the invention
The present invention reduces the pollution to environment simultaneously in order to improve the zinc coating solidity to corrosion, makes simultaneously not contain hexavalent chromium in the plating bath and invented Bandaid pipe trivalent chromium green black colour passivator.
The present invention adopts chromium chloride, propanedioic acid, and Trisodium Citrate, copper sulfate, S-WAT, materials such as sodium laurylsulfonate are formed Bandaid pipe trivalent chromium green black colour passivator.
Concrete preparation method of the present invention comprises the step of following order:
A. the chromium chloride of calculated amount is poured in the less water, stirring is fully dissolved it;
B. the Trisodium Citrate with calculated amount slowly adds, and stirs it is fully dissolved;
C. the propanedioic acid of calculated amount is poured into, is stirred, it is fully dissolved;
D. the copper sulfate with calculated amount slowly adds, and it is fully dissolved;
E. the S-WAT with calculated amount slowly adds, and it is fully dissolved;
F. the sodium laurylsulfonate with calculated amount slowly adds, and the constant volume post-heating fully dissolves it;
G. left standstill 10 minutes, and after nitric acid accent pH is in 1～2.5 scope, began passivation.
H. behind passivation 10～20s, carry out sealing treatment with encapsulant.
Gained Bandaid pipe trivalent chromium green black colour passivator of the present invention is for clarification is cyan liquid.
Description of test
The present invention implements Passivation Treatment through after carrying out zinc-plated experiment in trivalent chromium deactivating liquid, carry out the encapsulant sealing treatment, through after the processing of different time, observes the color and luster of coating, and carries out neutral salt spray test and measure its corrosion resisting property.
Embodiment
The concrete preparation process of present embodiment is following:
A. prepare general low-cyanide zinc plating solution, and adjustment pH value, electroplate.
B. take out sample behind the certain hour, in 3% nitric acid, carry out Passivation Treatment after the bright dipping, passivation time is from 10～20s.
C. the workpiece after the passivation is used the encapsulant sealing treatment.
D. observe the color and luster that transforms rete, and carry out neutral salt spray test.
Bandaid pipe trivalent chromium green black colour passivator is:
Encapsulant
pH 1～2.5
The temperature room temperature
Passivation time 10～20s.
Claims (1)
1. Bandaid pipe trivalent chromium green black colour passivator is characterized in that the principle of passivator is formed as follows: chromium chloride 40g/L, propanedioic acid 10g/L; Copper sulfate 20g/L, Trisodium Citrate 10g/L, S-WAT 20g/L; Sodium laurylsulfonate 2g/L; All the other are water, and the pH value maintained in 1～2.5 scope when trivalent chromium green black colour passivator used, and carried out sealing treatment with encapsulant after the passivation.
