6, that is, complete the preparation of single side H-type embossing PCM color painted steel strips.
The prime coat 4, back of the body enamelled coating 8 and top coat layer 5 are all made of environment-friendly epoxy polyester paint.
The present invention also provides a kind of chromium-free passivation liquid, the formula of raw material by weight is as follows：
50 parts of chromic salt, 8 parts of oxidant, 8 parts of complexing agent, 8 parts of film forming accelerating, 15 parts of lanthanide series metal, stabilizer 5
Part, 5 parts of novel block agent, 5 parts of complexant, 5 parts of catalyst.
In summary：1) chromic salt：Chromic salt is the main compound to form passivating film.It is most widely used at present
It is chromium chloride, chromium sulfate, chromic nitrate, also someone mentions with chromium phosphate, chromic acetate.It is Cr in Passive Film (VI) and Cr (1lI)
Source.The readily soluble mesh of Cr in Passive Film (V1) compound is softer, it is distributed in the inside of film, plays a part of filling gap：In tide
It can also ooze out, be dissolved in the solidifying mist of film surface from film layer in wet air, and dissociating chromic acid makes zinc coating be passivated again.And Cr
(II) compound has higher stability, indissoluble, intensity good, plays the skeleton function of film.There is no Cr (III) compound, then it is blunt
The color for changing film is very light, in conjunction with force difference, but it is too many when, film layer can virescence.
Colored passive films can be obtained between 35-70g/L in the mass concentration of chromic salt.The height of trivalent chromium salt concentration
It is low, influence the thickness and color and luster of passivating film.Trivalent chromium salt concentration is higher in processing range, and passivation film thickness is thicker, and color and luster is got over
Dense, film surface is more uniform.When the mass concentration of chromic salt is 60g/L, best passivating film can be obtained；When the quality of chromic salt
When concentration is more than 75g/L, passivating film rough surface, passivating film is dimmed, there is dark line or hickie；The mass concentration of chromic salt is less than
When 30g/L, passivation time is long, and the color and luster of film is very light；It cannot get colored passive films when too low.
2) oxidant：Sulfuric acid plays the role of accelerating film forming speed, while having the effect for preventing passivating film hair mist concurrently.But it contains
Amount must be adapted with chromic anhydride content, that is to say, that the ratio of CrO and sO is the key that control passivating film color.When sulfuric acid contains
When measuring excessively high, the dissolving of film can be accelerated, reduce film forming speed instead, but it is too low when, the color of passivating film is too light, and nitric acid can be excellent
It first dissolves at zinc coating dimpling and plays the role of leveling, enhance the glossiness of film.But nitric acid should not be too many, and otherwise zinc coating dissolves
It is too fast, keep film layer thinning, influences corrosion resistance.
Nitrate is oxidant, is reacted with zinc coat and generates zinc ion, passivating film is promoted to be formed.Nitrate anion has zinc coating
Certain goes out light action, and the bright property on passivating film can be improved.Common oxidant has hydrogen peroxide, nitrate, chlorate, over cure
Hydrochlorate, quadrivalent cerium.When the mass concentration of nitrate is 12g/L, the gloss of passivating film and other apparent forms are optimal.Nitrate
When mass concentration is more than 30g/L, obtained passivating film apparent form is deteriorated；When less than 5g/L, passivating film is not bright.
3) complexing agent：The stability that film forming speed and passivating solution can be controlled, such as organic carboxyl acid and its mixture, it is appropriate to select
Complexant, be a highly important parameter for obtaining high-quality passivating film and the passivating solution stablized.The complexing agent master of the first generation
To be fluoride, film layer is relatively thin, and corrosion resistance is poor, and neutral salt spray test was generally difficult to more than 16 hours.And the Cr of the system
(III) concentration is higher, and operation temperature is also higher.The trivalent chromium deactivating liquid of second generation early stage contains oxidant, corrosion resistance and film layer
Color is similar to Cr VI, but since film layer contains Cr VI therefore is eliminated, and late stage process is without oxidant but multicolored color
It is thin.The trivalent chromium passivator that we research and develop the second generation uses based on organic complexing agent, and other metal corrosion resistances are added can be big
It is big to improve, and the passivating film of different colours can be obtained, such as blue white, five colours, black, operating condition requires relatively low.
4) film forming accelerating：Passivation film color can be adjusted, such as certain inorganic or organic anion.
5) lanthanide series metal：Appearance color is adjusted, with corrosion resistance.Such as lanthanide series rare-earth elements.
6) stabilizer：Stablize passivator in trivalent chromium valence state and passivator pH value, acetic acid is buffer, rise stablize it is blunt
Change the effect of liquid pH value, but also has an impact to the color and luster of passivating film.
7) novel block agent：Nano material and nanometer new technology are introduced, the corrosion resisting property of passivating film is substantially increased.
8) complexant:Tartrate or citrate are complexants, control the rate of film forming and the stability of passivating solution.It is logical
Common complexant has fluoride, ammonium salt, acetate, citrate, tartrate.It is blunt when its mass concentration is 12~25g/L
The quality for changing film is all good.When less than 12g/L, passivating film color and luster is dim；But when higher than 30g/L, passivating film is very thin, color and luster pole
It is light, and film layer is uneven；When its mass concentration is 20g/L, the apparent form of passivating film is best.
Catalyst：The main appearance and corrosion resistance for influencing passivating film of effect of catalyst.Logical common transition metal ion, such as
Ferrous ion, nickel ion, manganese ion, cobalt ions, titanium ion, molybdenum ion, cerium ion.The mass concentration of catalyst is in 4~5g/
When L, the apparent form of passivating film is all fine.The concentration of transition metal is higher in processing range, and passivating film is thicker, and color is got over
It is deep.When less than 2g/L, passivating film paler colour, film is uneven；But when higher than 17g/L, passivating film has hickie and grey.

Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
