Abstract
The invention provides a passivation treating agent for a chromium-plating steel part, and relates to the technical field of chemical engineering. The passivation treating agent comprises the following components in percentage by mass: 3% of potassium hydroxide, 45% of chromium nitrate, 5% of n-octanal, 4% of graphene, 20% of malonic acid, 10% of oxalic acid, 3% of silica gel-loading zirconium sulfate and the balance of tertiary butanol. The passivation treating agent provided by the invention is long in using period, does not contain hexavalent chromium and hydrogen peroxide or other strong oxidants, facilitates wastewater treatment and is an environment-friendly passivation agent. The passivation treating agent is low in concentration and production cost, relatively economic and practical and capable of improving the salt mist resistance and corrosion resistance of a metal surface and prolonging the service life of the steel part.
Description
Technical field
The present invention relates to chemical technology field, be specifically related to a kind of electrodeposited chromium steel part passivation treating agent.
Background technology
Steel-iron components is at electrodeposited chromium or hot dip chromium or conventionally all will carry out afterwards Passivation Treatment, to prevent producing white rust in the short period of time.Because chromium coating is easy to produce white rust under moist environment, have a strong impact on attractive in appearance and work-ing life, so conventionally need to carry out Passivation Treatment after steel part chromium plating.Traditional passivator, because contain carcinogenic sexavalent chrome, causes serious pollution to environment, is now replaced by the trivalent chromium passivator of environmental protection gradually.Early stage trivalent chromium passivator is by chromic acid (Cr0
3) and reductive agent (for example potassium pyrosulfite) reaction.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cost low, the electrodeposited chromium steel part passivation treating agent of environmental protection.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of electrodeposited chromium steel part passivation treating agent, is made up of the component of following mass percent:
Surplus is the trimethyl carbinol.
The better quality umber of each component is:
Surplus is the trimethyl carbinol.
The invention has the beneficial effects as follows: passivator life cycle of the present invention is long,, containing sexavalent chrome, be not easy to wastewater treatment, also do not contain hydrogen peroxide or other strong oxidizer, is a kind of passivator of environment-friendly type; And concentration is low, production cost is low, comparatively economical and practical, can make salt fog resistance, corrosion resistance and the work-ing life of metallic surface extend.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment 1
A kind of electrodeposited chromium steel part passivation treating agent, is made up of the component of following mass percent:
