Description
Technical field
The present invention relates to galvanizing surface processing technology field, refer more particularly to a kind of zinc-plated sealer and preparation method thereof.
Background technology
The zinc-plated main corrosion protection coating as steel and iron parts, ranks first in plating processing capacity, removes because process unit is relatively low
Outward, the zinc coat in steel and iron parts is anodic coating, and when making moist and electrochemical corrosion occurs, zinc first corrodes and makes steel-based
Body is protected.But zinc is originally as amphoteric metal, the most acidproof the most alkaline-resisting, is readily generated basic zinc carbonate in an atmosphere
The even white hair of erosion and long white macula, white lime.It is passivated again after zinc-plated processing, slushing oil can be improved to some extent, prolong
The time of long zinc corrosion itself.Therefore Passivation Treatment to be done after electrogalvanizing, but drying aging, passivation after again
Make sealing treatment again than not closing after passivation, aging far better, but the sealer effect used at present is not
Substantially, the appearance of coat out-of-flatness of sealer, corrosion-resistant, abrasion resistant coatings is poor with basal body binding force.
Summary of the invention
The technical problem to be solved is to provide a kind of zinc-plated sealer and preparation method thereof, to overcome prior art to seal
Closing agent appearance of coat out-of-flatness, corrosion-resistant, the defect such as wear no resistance.
For solve above-mentioned technical problem, the present invention by the following technical solutions:
A kind of zinc-plated sealer, it is characterised in that include the raw material of following weight portion: Coupling aniline 20-30 part, benzene
