Another object of the present invention, which also resides in, provides the application of above-mentioned tin plate, using the tin plate as film-covered iron base
Plate.
The beneficial effects of the present invention are: the preparation method of tin plate of the present invention, the first passage and most during electrotinning
Extreme trace primary current density is 10~20A/dm2, pony-roughing pass current density is 5~10A/dm2；I.e. by first of primary current density
It is limited to 10~20A/dm2, biggish current density can make forming core rate be greater than nuclei growth rate, make obtain crystal grain more
It is careful, therefore last a time that plating is come into operation still uses high current density to guarantee that surface layer grain is fine and close, last
Passage current density is limited to 10~20A/dm2, pony-roughing pass should reduce cathodic polarization with limit forming core promote crystal grain grow up, electricity
Current density is limited to 5~10A/dm2；By the design in above-mentioned plating process of tin, the uniformity of tin coating is improved.In addition,
The present invention uses pure induction reflow technique in the softening-melting process, and the temperature of soft heat is 240~245 in the softening-melting process
DEG C, the time of soft heat is 0.5~1.5s；In order to improve the problem of low tin coating weight welding performance difference, imitated by using above-mentioned heating
Rate is fast and controls induction reflow heating method with high accuracy, and cooperates suitable reflowing temperature and Reflowing Time, both ensure that plating
The corrosion resisting property of sheet tin makes low tin coating weight tin plate meet welding requirements again；Moreover, being chemically combined to improve with PET film, this hair
It is bright that electrochemical passivation is carried out as passivating solution using the high concentration sodium dichromate of 27~31g/L after soft heat, so that of the invention
Tin plate and PET film binding force are good.
Specific embodiment
The present invention solves existing by providing a kind of preparation method of tin plate and the application of thus obtained tin plate
It the production technology of pole low tinplating steel sheet and its applies in the defects of film-covered iron.
To solve the above-mentioned problems, the main thought of the embodiment of the present invention is:
The preparation method of tin plate of the embodiment of the present invention includes the following steps: to include by strip successively electroplated tin, soft
Molten, passivation and oiling, obtain finished product；
Wherein, the first passage and most end passage current density are 10~20A/dm during the electrotinning2, interim orbit
Primary current density is 5~10A/dm2；
In the softening-melting process use pure induction reflow technique, in the softening-melting process temperature of soft heat be 240~
245 DEG C, the time of soft heat is 0.5~1.5s；
It is the sodium dichromate solution of 27~31g/L as passivating solution that concentration is used in the passivating process.
Above-mentioned strip can also be used conventional cleaning treatment technique removal surface Residual oil and oxide layer and restore before electrotinning
Surface-active state, such as lye hydro-peening, electrolytic alkaline cleaning.
Since tin plate sheet surface is microcosmic uneven with certain roughness, it will lead to local current densities during electrotinning
Unevenly, it needs first passage to come into operation in electroplating bath to increase cathodic polarization and improves nucleation rate, reduction current unevenness is even
Problem increases crystal grain coverage rate, while being considered as avoiding the generation of evolving hydrogen reaction, first of primary current density limitations 10~
20A/dm2, biggish current density can make forming core rate be greater than nuclei growth rate, make obtain crystal grain it is more careful, because
Last a time that this plating is come into operation still uses high current density to guarantee that surface layer grain is fine and close, and last a time electric current is close
Degree is limited to 10~20A/dm2, pony-roughing pass should reduce cathodic polarization with limit forming core promote crystal grain grow up, current density limit
In 5~10A/dm2.To guarantee that electroplating efficiency is stablized 85% or more, and guarantee that electro-deposition matches with current density, strip fortune
Scanning frequency degree should be set in 200~300m/min, Sn in electroplate liquid2+Concentration is set in 10~25g/L.
Softening-melting process should eliminate the pin hole after electrotinning in tin layers, formed between tin layers and iron substrate have it is certain resistance to
The alloy-layer of corrosion keeps pure tin amount in 0.15~0.25g/m again2, good surface brightness and welding performance are obtained, therefore
High, the fast induction reflow heating method of heating speed using control temperature accuracy, limits 240~245 DEG C of reflowing temperature, when soft heat
Between 0.5~1.5s.
To promote the hydrated chromium oxide that can be firmly combined with polar group on PET film to be formed in passivating process, passivating solution is dense
Degree is set in 27~31g/L, and passivating solution temperature is set in 40~44 DEG C, and passivating solution pH value is set in 4.2~4.6, is passivated charge
Density is set in 3~5As/dm2。
In addition, in order to guarantee to avoid a generation for rust that from should carrying out at oiling in inventory and transportational process after low tin coating weight output
Reason, oiling type use sebacic acid dibutyl ester, apply oil mass and are set in 5~7mg/m2。
In conclusion the embodiment of the present invention passes through in such a way that electroplating technology section is using high current forming core, low current crystallization
And strip speed and Sn that matching is certain2+Concentration ensure that the uniformity that tin layers are distributed under low tin amount, while soft using incuding
Molten heating method quickly accurately reaches set temperature, and coating pure tin amount is in 0.15~0.25g/m after ensure that alloying2, make
The tin plate has excellent welding performance and corrosion resisting property, and passivation guarantees passivation using high sodium dichromate solution and current density
The amount and structure of film are obtained the adhesion performance excellent with PET film, and can both be protected before strip coiling using appropriate DOS oil
Card surface quality in turn avoids coating bad problem in coating process.
It is 0.5g/m that total tin coating weight, which can be obtained, in the embodiment of the present invention2Pole low tinplating steel sheet, the present invention in for save life
It produces cost consideration and replaces chrome plating to be applied to film-covered iron with pole low tinplating steel sheet,
Conventional tin plate tin coating weight specification limit is generally in 1.1g/m2~11.2g/m2, tin coating weight is low in currently available technology
In 1.1g/m2Extremely low tin products application it is also less, pole low tinplating steel sheet is primarily present tin plating unevenness in process of production
Alloying, which occurs, for even, soft-melting process section pure tin and base iron causes coating pure tin amount too low, and alloy-layer and substrate exposed area increase,
In subsequent tank welding process processed contact resistance it is excessive cause bad welding performance, rust spot incidence in inventory and transportational process
The problems such as high, in conjunction with the development trend of tin plate market coating thinnedization, the embodiment of the present invention devises above-mentioned tin coating weight 0.5g/
m2Extremely low tin tin plate, welding performance uniform with coating is good, is greater than the advantage of 500N/m with PET film binding force, can
It substitutes chrome plating and is applied to film-covered iron.
