Abstract
Provided is a method for producing a surface-treated steel sheet which is used in a resin-coated steel sheet and which has excellent processed adhesiveness when worked by rigorous molding. The method for producing a surface-treated steel sheet involves adjusting the Sn concentration in a tin sulfate plating bath containing sulfuric acid and tin sulfate to within a range of 30 to 120 g/L, the tin sulfate plating bath temperature to within a range of 20 C to 60 C, and the current density in the tin sulfate plating to within a range of 2 to 50 A/dm2, and also involves coating the steel sheet surface with metallic tin in such a way that the percentage of the steel sheet surface covered by tin is 5% to 95% and some of the iron at the steel sheet surface is exposed.
Description
Technical field
The present invention relates to the manufacture method of the surface treated steel plate that a kind of resin-coated steel sheet of processing tackyness excellence uses.
Background technology
In recent years, the steel plate of coated with resin first carries out stretching processing after stretch process or stretch process again, after stretch process, carry out again impact extrusion processing, after stretch process, remerge and stretch the processing etc. that processing and impact extrusion are processed, at the bottom of applying the can body of harsh processing and tank, one shapes the tank body of making, cover in seaming again, and produce tank.In order to allow these tank bodies in harsh shaping processing and after shaping processing, coated with resin can not be peeled off or be ruptured, and resin must have excellent tackyness to steel plate.Therefore, the material that these tank bodies are used, has used the chromic acid such as tin-free steel (TFS) that forms the chromic acid epithelium of processing tackyness excellence on surface to process on steel plate, and the resin-coated chromic acid of coating organic resin is processed steel plate.
But, the tank body that uses resin-coated chromic acid to process steel plate has a problem, when penetrating into the fine hole of steel plate surface if produce on resin layer or chapping, because chromic acid is processed steel plate shortage erosion resistance, while particularly having filled the high content of acid degree, steel plate can promptly corrode.
So, use fill the high content of acid degree in tank time even if attempt in the past, also possesses the resin-coated tin electroplating steel plate of coated with resin on the tin plate of excellent anticorrosive, but resin is to tin coating tackyness, particularly add the film processing tackyness in man-hour at tank body not good, even if therefore need to develop in above-mentioned harsh processing purposes, still can possess the material of excellent film processing tackyness.Especially tinplate is because of tin Acidulent film and the low impact of coating temperature, and film tackyness is poorer than TFS, is also a problem.
In general, the electroplating steel plate that beverages can uses mainly contains tinplate (tin plate) and TFS (electrolysis chromium plating steel plate), when filling the high content of corrodibility, can utilize the sacrifice corrosion protection effect of tin, tinplate possesses more excellent erosion resistance than TFS.Tinplate is because there be exist (the hindering the tackyness with organic resin film) of tin Acidulent film, and (tin meeting melting is with mobility more than the melting point of tin (232 DEG C) to be difficult to coating, be attached on heating installation), so difficult coating more than the melting point of tin, real current situation is that the film tackyness after tank processed is poorer than TFS.
On the other hand, although the erosion resistance of TFS is not as good as tinplate, but there is the chromic oxide epithelium of film tackyness excellence on top layer, the film tackyness after simultaneously also can temperature coating (melting point of chromium the is about 1800 DEG C) tank processed more than 232 DEG C is also good than tinplate.
In order to address the above problem a little, in patent documentation 1, disclose on the tin coating without molten tin electroplating steel plate (not carrying out the tin plate of steel melting treatment) or melting tin plate (carrying out the tin plate of steel melting treatment), silane coupling agent coating layer is set, then lamination organic resin epithelium and the resin-coated copper electroplating steel plate that forms.
Patent documentation 1: JP 2002-285354 communique
But, the processing of the resin-coated copper electroplating steel plate of patent documentation 1, need to add new processing, except meeting improves the manufacturing cost of tinplate, impose again after stretch process if carry out and stretch processing and impact extrusion is processed and uses, the shaping of carrying out tank body adds man-hour, may occur that resin peels off on the top of tank body that is shaped in processing way, and tank body adds the processing tackyness existing problems of resin in man-hour.
Summary of the invention
The object of the invention is to address the above problem, add man-hour even if provide in harsh shaping, also can have the manufacture method of the surface treated steel plate that the resin-coated steel sheet of excellent processing tackyness uses, and the resin-coated steel sheet of coated with resin on surface treated steel plate.

Embodiment
Below will describe example of the present invention in detail.
[steel plate]
The steel plate using as the raw sheet of surface treated steel plate of the present invention, in general, can use after the tempering of tank carbon aluminium-killed steel hot rolling calendering steel plate according to different purposes, the modified cold-rolled steel sheet of delaying thickness of slab=0.15～0.3mm that rolls, or use and impose again cold rolling calendering after tempering with the cold-rolled steel sheet of gaining in strength etc.In addition also can use by the cold-rolled steel sheet of non-ageing ultra-low carbon steel manufacturing that has added niobium, titanium.Above-mentioned cold-rolled steel sheet is carried out, after electrolytic degreasing, pickling, forming tin coating on steel plate, make surface treated steel plate.
[plating tank]
In the present invention, surface treated steel plate uses tin sulphate plating tank.
The composition of tin sulphate plating tank is tin sulphate concentration (being Sn concentration)=30～120g/L,
Also can add other interfacial agent or antioxidant etc.
Plating condition is:
Electroplating current density: 2～50A/dm
2,
Plating tank temperature: the scope of 20～60 DEG C.
Tin sulphate concentration is Sn concentration during less than 30g/L,
Even reduction current density, Sn separates out form and also can not become the state (floor iron exposes) that exposes floor iron, when coated with resin, cannot promote tackyness.
On the other hand, when tin sulphate concentration (being Sn concentration) exceedes 120g/L, concentration easily changes, and is difficult to carry out correct electroplating operations.In addition, if pH is too low, the corrodibility of electroplate liquid can uprise, and may make electroplate liquid be polluted.
Electroplating current density: 2～50A/dm
2reason, if be because less than 2A/dm
2, till electroplating processes finishes to need the long period, sometimes may, because of variation of electroplating bath components etc., cause being difficult to correctly carrying out electroplating operations.
On the other hand, if exceed 50A/dm
2, can form the plating of comprehensive coating, do not have the iron of bottom to expose.
Plating tank temperature: the reason of 20～60 DEG C, if top layer tin area occupation ratio will be more than 95% less than 20 DEG C, become the state that approaches comprehensive coating (exposing without floor iron), film tackyness is obviously reduced.
On the other hand, if exceed 60 DEG C, in electroplate liquid, the concentration of composition easily changes, and is difficult to carry out correct plating.
[surperficial tin area occupation ratio]
Be scattered in and on steel plate, make its metallic tin of separating out shared area on steel plate, that is surperficial tin area occupation ratio, it is desirable to 5～95%.
If surface copper area occupation ratio is less than 5%, erosion resistance and processibility will obviously worsen, and at least need more than 5% tin area occupation ratio.
If surface copper area occupation ratio exceedes 95%, the exposed area of iron will reduce, and cannot improve the tackyness of resin layer.In order to improve the tackyness between resin layer, the area that exposes of iron is at least necessary for more than 5%.
Surperficial tin area occupation ratio on this steel plate, taking electron microscope observation surface gained as the first image, carry out after chemical removes disperseing to be present in tin on surface of steel plate, observe gained person as the 2nd image taking electron micrograph once again, gained two images are compared and obtained with computer image processing.
[the zinc-plated amount of metallic tin]
The zinc-plated amount of the metallic tin on surface of steel plate, from making more than 5% viewpoint of iron surface exposed area it seems, it is desirable at 0.1～3g/m
2scope in.
It is desirable to is 0.5～5.6g/m
2.If zinc-plated amount is less than 0.1g/m
2, erosion resistance deficiency, unsatisfactory.Especially while carrying out tin melting (Reflow) processing, the tin of all plating all alloy turns to Fe-Sn, and except erosion resistance, processibility is also showing and worsening, and therefore at least needs to have 0.1g/m
2above zinc-plated amount.
On the other hand, if exceed 13g/m
2, iron cannot expose to surface, cannot improve the tackyness of resin layer.
[the tin coating that makes iron surface expose]
Though the tin of electroplating on steel plate forms the reason of the state that exposes of iron surface and does not illustrate completely, is forming on the iron surface of Acidulent film, carry out a small amount of when zinc-plated, the wetting property of tin each part of ferroelectric oxide film neither with, therefore be difficult to form the tin coating of same thickness.
In addition, the average particulate size of metallic tin (from the mean diameter of the particle dia of viewed in plan) it is desirable to 0.5～50 μ m.
It is desirable to 2～20 μ m.Less than 0.5 μ m, size of particles is too small, can not obtain the concavo-convex resin layer bringing and throw anchor effect (anchor effect), cannot improve the tackyness of resin layer.
On the other hand, when average particulate size exceedes 50 μ m, due to the restriction in electrolysis treatment, will make tin electroplating become difficulty.
[lamination of resin layer]
As the one or two sides of the surface treated steel plate of above-mentioned manufacturing, lamination forms the resin molding of resin layer.Resin layer it is desirable to heat the still thermoplastic resin of excellence of post-treatment, for example polyethylene terephthalate, polybutylene terephthalate, poly-naphthalic acid diethyl ester, ethylene glycol terephthalate-ethylene m-phthalate copolymer, the vibrin such as butylene terephthalate-m-phthalic acid fourth diester copolymer, or mix the resin of two or more these vibrin, polyethylene, polypropylene, ethylene-propylene copolymer zoarium, and these maleic acid modification person, ethane-acetic acid ethyenyl ester copolymer, the polyolefin resines such as ethylene-acrylic acid copolymer, nylon 6, nylon 66, the versamid 900s such as NYLON610, polycarbonate, polymethylpentene, mix by above-mentioned vibrin and ionic polymer the single-layer resin layer forming in addition, with by two or more the formed multi-layer resinous layers of above-mentioned resin etc.
The thickness of resin layer, consider the accessibility of resin layer lamination operation, the viewpoint of upper tack strength, erosion resistance and the economy etc. with resin layer surface processing steel plate of the molding (tank etc.) that is shaped after processing at resin-coated steel sheet, it is desirable to is 10～100 μ m.
These resin layers are by resin particle heating and melting, with the T-shaped die head extrusion of extruder (I), make after the film of desired thickness, then the surface treated steel plate of the formation metallic tin that exposes in iron surface of lamination form.
The lamination method of this resin layer, can be used for example hot joining method, resin molding is connected on the surface treated steel plate that is heated to specific range of temperatures, and clamps from two sides with a pair of pressing roller, with the joint that pressurizes.
In addition,, on the surface treated steel plate of manufacture method manufacturing of the present invention, even if the resin molding of masking is the resin molding that imposes deep processing, twin shaft orientation, still can for example, carries out heat higher than the temperature of tin melting point temperature (250 DEG C) and stick together.

As illustrated above, use the resin-coated steel sheet with the surface treated steel plate of manufacture method manufacturing of the present invention, carry out after stretch process, pull stretch processing, stretch process after processing again carrying out again impact extrusion processing no matter be, adding man-hour resin molding in shaping neither can peel off, present stable, in addition, even impose the tank body that stretches processing and impact extrusion processing and be shaped and add man-hour imposing to remerge after harsher stretch process, resin molding can not be peeled off, and presents stable and excellent processing tackyness.
In addition, the assessment of the tackyness of coated with resin in the past, be before processing, under dull and stereotyped state, to measure T peel strength, but this measuring method may not necessarily correctly reflect processing tackyness, and therefore, stripping strength in the present invention adopts S peel strength.In other words, stretches processing and impact extrusion process the to be shaped harsh shaping of tank body and add man-hour carrying out after pull processing merging again, S peel strength is tackyness (processing tackyness) Evaluation Method that can correctly reflect in processing and after processing.
So-called S peel strength, refers to that resin-coated steel sheet imposes stretch process shaping and is processed as cup, cuts out test piece by cup side post, with the resin molding stripping strength assessment processing tack strength of this test piece.
The concrete measuring method of S peel strength intensity shows below.
First, stamp out the plate body of diameter 154mm at resin-coated steel sheet, impose first paragraph stretch process with pull ratio=1.64, be configured as the pull cup of diameter 96mm, height 42mm.On the side wall portion of this pull cup, cut out cup height direction 30mm, cup circumferential direction: 120mm size, back bending becomes after tabular, strikes out the T word shape test piece 71 of the size as shown in the orthographic plan of Fig. 2 with pressing mold.
Then as shown in Figure 3, with cutter folk prescription (right side) the end 71a's of test piece 71 and tack strength measure the coated with resin (the rear side in diagram) of face (the front side in diagram) opposition side, draw the upper degree of depth and reach the score 72 of surface treated steel plate.
Again as shown in Figures 4 and 5, use indentation die for processing group, measuring upper the drawing after upper indentation 3 in face opposition side (side of stroke upper score 72) with tack strength, bend indentation portion, only severing surface treated steel plate.Now, on tack strength mensuration face, coated with resin is severing not, is also connected to the surface treated steel plate two ends that separated by severing and is retaining.
Then as shown in Figure 6, test piece end 71a is inserted to the test piece insertion section 74a of test piece fixer 74, test piece 71 is fixed on after test piece fixer 74, by the other end 71b of the top 74b of test piece fixer 74 and test piece 71, two chucks with tensile testing machine are clamped stretching, measure the tensile strength of coated with resin when surface treated steel plate is forced glass, this numerical value is S peel strength.
As above the S peel strength measured, in the time that the width of test piece is 15mm, it is desirable to more than 0.2kg/15mm.S peel strength does not reach 0.2kg/15mm, remerges in the harsh shaping processing such as tank processing processed of stretching processing and impact extrusion processing after stretch process, cannot obtain and stabilize good processing tackyness.
The present invention is by promoting the shortcoming of existing surface treated steel plate, that is with the tackyness of resin, manufactured unchangeably and do not reduced the surface treated steel plate that resin-coated steel sheet processibility and erosion resistance promote, industrial value is high.
