Description

The coated steel of laser cutting, elementary rust-preventing characteristic and identification excellence
Technical field
The present invention relates to have concurrently excellent laser cutting (laser cutting performance) and elementary rust-preventing characteristic (primary rust prevention performance) and identification (legibility), the coated steel (painted steel) of the identification excellence of the word of especially printing with whitewash.
Background technology
In the manufactory (fabricators) of shipbuilding (ships), bridge (bridge), building machinery (construction machines) etc., as the cutting method of steel plate, laser cutting is because of advantages such as the automation of its dimensional accuracy (dimentional precision) high (± 0.5mm), the little and unmanned level of heat affecting (influence of heat) (without human interface) to parts are easier to, and usage trend increases.But, laser cutting exist compared with plasma cutting (plasma cutting) cutting speed slowly, the thickness of slab that can cut compared with gas cutting (gas cutting) is restricted the problem of (limitation of cutting plate thickness).
In addition, due to the priming paint (primer) of the elementary antirust processing as carrying out in manufactory (primary rust preventive treatment), the problem that exists the upper limit of laser cutting speed and the thickness of slab that can cut to reduce.Its mechanism (mechanism) it be unclear that, and reality is that each manufactory method that rule of thumb property obtains is processed.As one of processing method, have the pre-treatment that is known as prebake conditions (preliminary baking) in manufactory, the film (painted film) to cutting part is implemented the irradiation in advance (prior irradiation) of low power output laser (low output laser).By this pre-treatment, laser cutting improves, but because needs carry out 2 Ear Mucosa Treated by He Ne Laser Irradiations (laser irradiation) along actual line of cut (actual cutting line), thereby no matter be that loss is all large aspect operation or aspect the energy dropping into.Therefore, economic loss is also large.Therefore, people, to having very high expectation in the pre-treatment of not carrying out improving 2 times such Ear Mucosa Treated by He Ne Laser Irradiations of above-mentioned prebake conditions laser cutting, have proposed kinds of schemes so far.
For example, in patent documentation 1, in view of Zn contained in film (prime coat) can produce harmful effect to laser cutting, a kind of technology of measuring to improve laser cutting by restriction as the Zn in the film of antirust agent interpolation has been proposed.But Zn is to antirust effective element, restriction Zn amount can cause the rust-preventing characteristic of film to reduce, and the Zn in restriction film is measured to the rust-preventing characteristic causing reduces the method compensating but do not record in patent documentation 1.
On the other hand, about the technology that improves film rust-preventing characteristic, the technology of a kind of highly corrosion resistant coating (high corrosion resistant paint) being formed by the mixed-powder of Zn:65～85 % by weight, Al:3～15 % by weight by use as anticorrosive property heat-resisting, that anticorrosive coating improves film (corrosion resistant) (rust-preventing characteristic), heat resistance (heat resistant) proposed in patent documentation 2.But, in the technology proposing at patent documentation 2, do not consider laser cutting completely.And as shown in embodiment, in the technology proposing at patent documentation 2, in order to ensure highly corrosion resistant, the thickness during by application is set as the so thicker thickness of 75 μ m.Like this, along with the increase of thickness, (Zn+Al) amount contained in film also can increase, and likely causes laser cutting to decline.
In addition, in patent documentation 3, proposed a kind of by using the highly corrosion resistant coating being formed by the alloy powder of Zn-Al-Mg to improve the technology of the corrosion resistance of coated metal plate.But, in the technology proposing at patent documentation 3, due to Zn, Al and Mg are carried out to alloy powder (alloyed and powdered), thereby, with use monomer Zn powder, Al powder time compared with, coating manufacturing cost rises.In addition in the technology that, patent documentation 3 proposes, do not consider laser cutting completely yet.And as shown in embodiment, in the technology proposing at patent documentation 3, in order to ensure highly corrosion resistant, the thickness during by application is made as the so thicker thickness of 60 μ m.Therefore, the same with the technology proposing in patent documentation 2, because (Zn+Al) amount contained in film is many, thereby likely cause laser cutting low.
With respect to these technology, a kind of technology except adding zinc powder and aluminium powder, also adding titania powder has been proposed in patent documentation 4 in priming paint.And according to the record of patent documentation 4, according to its technology, by optimizing the content of titania powder contained in priming paint and zinc powder, aluminium powder, the laser cutting of coated steel and elementary rust-preventing characteristic can be improved.But in the technology that patent documentation 4 proposes, due to the titania powder containing adularescent, therefore,, there is the impalpable problem of the word of the manufacture mark that normally used whitewash is printed in order to show steel origin in the meeting albefaction of priming paint surface.

Summary of the invention
As mentioned above, in the technology proposing at patent documentation 1, any countermeasure is not taked in the reduction of the rust-preventing characteristic that the reduction of the Zn amount along with in film is occurred, exists because restriction Zn measures and causes the significantly anxiety of reduction of rust-preventing characteristic.In addition,, in the technology that patent documentation 2 and patent documentation 3 propose, owing to not considering laser cutting, and in the film that can be inferred by the thickness of film, contained (Zn+Al) amount is large, can think that laser cutting is poor.
In addition, in the technology proposing at patent documentation 4, though can obtain the coated steel of laser cutting and elementary rust-preventing characteristic excellence, but in actual manufacturing process,, there is the impalpable problem of the words such as normally used whitewash is printed in order to show steel origin manufacture mark in the steel surface albefaction of developing.In addition,, although there is the description that also can add coloring pigment in patent documentation 4, do not record feature and its addition of the concrete coloring pigment adding.So just occur due to the kind difference of the coloring pigment of selecting, the problem that laser cutting can reduce.
In fact, at the scene of making or working steel products, in order to distinguish kind, the origin of steel, conventionally can stamp word and mark at steel surface with whitewash, the identification of above-mentioned word and mark is one of important function in manufacture and the scene of making.
The present invention In view of the foregoing makes, aims to provide to have high in laser cutting when the laser cutting and rust-preventing characteristic is also excellent, and also identification, the coated steel of the film of the identification excellence of the word of especially writing with whitewash.
In order to address the above problem, in the technology that present inventor proposes patent documentation 4, affect identification, be especially printed on that coated steel is lip-deep, the various factors of the identification of the word that shows steel manufactures numbering etc. is studied.Its result, expects adopting the lightness (brightness) of Munsell value (Munsell value) to be formed on the required index of identification of the film coated surface of steel surface as raising.And find, the technology of utilizing patent documentation 4 to propose, the i.e. coloring pigment (color pigment) of the lightness by further adding the Munsell value that makes film coated surface in the film to containing titania powder, zinc powder and aluminium powder below 7.0, there is tremendous raising in identification.
In addition, reduce Munsell value, add black series pigments, but find in the system of having added the graphite known usually used as the black pigment of coating in film, laser cutting significantly reduces.Further various black series pigments are studied, found that, only have certain pigment can in the situation that not damaging laser cutting, make the Munsell value on dry coating surface below 7.0.These items do not have problems completely in common coating and film (or priming paint), are the intrinsic problems of film (priming paint) that (what propose in patent documentation 4 is such) as described above used in order to improve laser cutting.In addition, also find, by optimizing the content of the coloring pigment in film, can be in the case of not damaging the identification (identification of the word of writing with whitewash) improving the laser cutting of steel and elementary rust-preventing characteristic with Chinese white.In addition, also find, meet with respect to the adding ingredient amount (total amount of titania powder, zinc powder, aluminium powder) being coated with in film component the desirable relational expression that it is made stipulations by making the amount of coloring components (coloring pigment), can obtain the zone of reasonableness of coloring pigment content.

Detailed description of the invention
Below the present invention is specifically described.
Coated steel of the present invention is characterised in that, steel surface has dry coating, described film contains titania powder, zinc powder, aluminium powder and by one or two or more kinds illuminating colour forming in black iron oxide pigment, black calcined pigment, the content of above-mentioned titania powder is at 4.5g/m 226g/m above, 2below, the content of above-mentioned zinc powder is at 5g/m 230g/m above, 2below, the content of above-mentioned aluminium powder is at 0.1g/m 210g/m above, 2below, be A g/m at the content taking above-mentioned titania powder 2, above-mentioned zinc powder content be B g/m 2, above-mentioned aluminium powder content be C g/m 2, above-mentioned illuminating colour content be X g/m 2time, the value of the Y shown in following (1) formula is more than 0.010, below 0.200, and the lightness of the Munsell value on above-mentioned dry coating surface is below 7.0.
Y＝X/(A+B+C)…(1)
Here, " lightness of Munsell value " is the index of the bright degree in the color showing method that represents to specify in JIS Z8721 (1993).Represent the series of black～grey～in vain, taking desirable black as 0, desirable in vain as 10, by cutting apart in the almost equal mode of difference of lightness sensation between the two, represented with numeral.
Know, conventionally, the steel surface of processing at ball blast (shot-blasting) be coated with rich zinc (Zn) priming paint (zinc (Zn) rich primer) or containing yellow zinc chromate primer paint (zinc primer), carry out elementary antirust processing (primery rust prevention treatment), then, while steel being carried out to laser cutting, there will be cutting speed to reduce.The mechanism of laser cutting Speed Reduction now might not be clear, but infer that the main cause that laser cutting speed declines is, because the above-mentioned film carrying out as elementary antirust processing forms (primer painting (primer painting)), (1) reduction of the laser absorption rate (laser absorbency index) that film (elementary anti-rust agent for treatment (primery rust prevention agent)) causes, (2) binder resin (binder resin) in the film (elementary anti-rust agent for treatment) that heating when laser cutting causes, laser light scattering and absorption (scattering and absorption) that the decomposition (decomposition) of zinc powder and evaporation (vaporization) cause, (3) reduction of the dividing potential drop (partial pressure) of the assist gas (assist gas) (oxygen) that the gas producing causes etc.
Therefore, in the present invention, by adding the titanium dioxide (TiO that laser absorption is high in the film to coated steel 2) powder, improve the absorptivity of laser and solve the problem in above-mentioned (1), improve laser cutting.
At the initial stage of laser cutting operation, by laser is focused on to cutting part, its light energy is absorbed, and local rising of temperature of cutting part, melts.Now, if cover cutting part with the film that contains the titania powder that laser absorption is high, light energy by efficient absorption in film, thereby can improve laser cutting efficiency.
The laser absorption of titania powder and high from efficient effect of discharging slag in cutting groove.Therefore, by adding titania powder, the viscosity of the slag occurring when laser cutting reduces, and slag is efficiently discharged in cutting groove, like this, can also improve the aesthetics of cut surface, suppresses the appearance of the scum silica frost that is attached to the cut surface back side.
In addition, titania powder not only easily obtains, also less expensive, thereby using the present invention of titania powder is being also favourable aspect production stability and cost.
In order effectively to bring into play this effect, in the present invention, make the content of titania powder contained in the film (dry coating) of coated steel at 4.5g/m 226g/m above, 2in following scope.The content of titania powder is less than 4.5g/m 2time, the raising effect of laser cutting is little.On the other hand, the content of titania powder exceedes 26g/m 2time, have the anxiety that hinders uniform coating to form, affect rust-preventing characteristic raising.So, make the content of titania powder at 4.5g/m 226g/m above, 2below.Preferably at 8.0g/m 218g/m above, 2below.
In addition, zinc (Zn) powder is a kind of to improving the very effective composition of elementary rust-preventing characteristic, on the other hand, is again the composition that one causes the problems referred to above (2) and problem (3) to produce.Here,, if to eliminate the addition of the problems referred to above (2) and (3) contained zinc powder in object minimizing film, elementary rust-preventing characteristic reduces, and causes new problem to produce.So, in the present invention, suppress the zinc content of film, and add aluminium (Al) powder with the elementary rust-preventing characteristic effect of raising.
Even if contain aluminium powder in film, when laser cutting, these powder decompose, evaporate, and laser cutting are produced to dysgenic situation few.Therefore,, by add aluminium powder add zinc powder in film in, can in the case of not causing the problem of above-mentioned (2) and (3), guarantee elementary rust-preventing characteristic.
Consider from the angle of guaranteeing laser cutting and rust-preventing characteristic, preferably make the content of zinc powder contained in film (dry coating) at 5g/m 230g/m above, 2below.The content of zinc powder is less than 5g/m 2time, even if interpolation aluminium powder also has the insufficient anxiety of rust-preventing characteristic of coated steel.On the other hand, the content of zinc powder exceedes 30g/m 2time, also have the insufficient anxiety of laser cutting even if add titania powder.Therefore, make the content of zinc powder at 5g/m 230g/m above, 2below.Preferably at 13g/m 227g/m above, 2below.
In addition, aluminium powder is that the rust-preventing characteristic in order to suppress to be caused by reduction zinc powder addition reduces and adds, but in film (dry coating), the content of contained aluminium powder is less than 0.1g/m 2time, the anxiety that can produce effect and can not fully manifest.On the other hand, the content of aluminium powder exceedes 10g/m 2time, have the anxiety that hinders uniform coating to form, make on the contrary rust-preventing characteristic decline.Therefore, make the content of aluminium powder at 0.1g/m 210g/m above, 2below.Preferably at 0.5g/m 21.5g/m above, 2below.
As mentioned above, by the present invention, can obtain also excellent coated steel of the high and rust-preventing characteristic of laser cutting.But, if only like this, due to film coated surface (dry coating surface) the meeting albefaction that the interpolation of titania powder causes, the impalpable word of the manufacture mark that normally used whitewash is printed in order to show steel origin.Here, measured the lightness on the coated steel surface with the albefaction film obtaining by said method, found that, the lightness of Munsell value is in 7.5 left and right.
Therefore, present inventor is easily studied by the Munsell value of the visual steel surface of distinguishing the word that can make to write with whitewash, found that, need to make this value below 7.0.For these reasons, in the present invention, make to be formed on film on steel for except titania powder, zinc powder, aluminium powder, the film of the coloring pigment of the lightness that also contains the Munsell value that makes film coated surface below 7.0.
As mentioned above, make the lightness of Munsell value below 7.0, just can form and normally used rich zinc (Zn) priming paint or the film that contains yellow zinc chromate primer paint have the film coated surface (coated steel surface) of equal gray system tone, even and if then while printing with whitewash the word etc. of manufacturing mark on coated steel surface, also can easily identify word.In addition, consider from the angle of identification, the lightness of preferred above-mentioned Munsell value is below 6.3, more preferably below 5.8.But the lightness of above-mentioned Munsell value is less than at 5.0 o'clock, have no alternative but to reduce the content of the white titania powder in the composition that forms film, and along with the reduction of titania powder content, laser cutting may be deteriorated.Therefore, the lightness of preferred above-mentioned Munsell value is more than 5.0, more than 7.0.In addition, more preferably more than 5.5, below 6.5.
In the present invention, the black for the lightness of Munsell value that makes dry coating surface below 7.0 be coloring pigment as described above, only limit to specific kind.Present inventor finds, use conventionally while containing carbon as the coloring pigment of main component to the carbon black (carbon black) adding as black series pigments in coating, graphite (black lead), black organic pigment (organic pigment) etc., the laser cutting of coated steel is and reduces tendency.By inference, this be due to when in film, contain taking carbon as main component coloring pigment time, the oxidation reaction (oxidation reaction) during due to laser cutting produces CO gas/CO 2gas, reduces the partial pressure of oxygen (oxygen partial pressure) of cutting part, and cutting power declines.Therefore, carbon black, graphite, black organic pigment etc. are not suitable for being used as in the present invention coloring pigment, need in the present invention to use black iron oxide pigment, black calcined pigment.Black iron oxide pigment, black calcined pigment be sometimes also referred to as complex oxide pigment, and for example, known have a Fe 3o 4a lot of these type of pigment such as system, Fe-Cr system, Fe-Cr-Ni-Mn system, Co-Fe-Cr system, Cu-Cr-Mn system, but be not limited to this, as long as carbon containing and pigment organic, taking inorganic constituents as main body all can not use substantially.
As mentioned above, in the present invention, be except containing titania powder, zinc powder, aluminium powder by the film that makes to be formed on steel, the film of the coloring pigment of the lightness that also contains the Munsell value that makes dry coating surface below 7.0, can obtain laser cutting, rust-preventing characteristic excellence and identification, the identification of the word of especially writing with whitewash is the coated steel of excellence also.
In addition with regard to the addition of coloring pigment, be A g/m at the titania powder taking contained in film (dry coating), 2, zinc powder is B g/m 2, aluminium powder is C g/m 2, coloring pigment is X g/m 2time, the value of the represented Y of (1) formula: Y=X/ (A+B+C) is more than 0.010, below 0.200.Y value as the ratio of titania powder, zinc powder, the total content of aluminium powder and the content of coloring pigment of contained white color system material in film (dry coating) 0.010 when above, the lightness of Munsell value is below 7.0, identification improves.Preferably more than 0.030.
On the other hand, above-mentioned Y value exceedes at 0.200 o'clock, sometimes has situation that laser cutting reduces, in corrosion resistance evaluation, is visually observed the situation that occurs the red rust causing as the black iron oxide of coloring pigment.The reason that occurs these situations it be unclear that, but infers it is the existing due to ratio reduces of the titanium dioxide high because of the laser absorption on coated steel surface.In addition, above-mentioned Y value exceedes at 0.200 o'clock, sometimes also there will be corrosion resistance (rust-preventing characteristic) deteriorated.Therefore, make above-mentioned Y value below 0.200.Preferably below 0.100.
In addition, if the coloring pigment adding exceedes 1.0g/m 2, the identification while writing word etc. with whitewash on steel plate further improves, and on the other hand, addition exceedes 5.0g/m 2time, sometimes corrosion resistance, laser cutting are produced harmful effect, thereby make the content of coloring pigment contained in film (dry coating) at 1.0g/m 25.0g/m above, 2below, preferably make the value of the Y that above-mentioned (1) formula represents more than 0.030, below 0.200.
In addition, in the present invention, preferably to adding one or two or more kinds the element in Mo, W, Ni, Cu, P, Mg, V, Co, Sn, Sb with ormal weight in above-mentioned dry coating.By elements such as independent in above-mentioned film or compound interpolation Mo, W, Ni, Cu, P, Mg, V, Co, Sn, Sb, rotproofness further improves.In addition, the reason that makes by this method corrosion resistance further improve it be unclear that, but infer it is can form fine and close corrosion product (corrosion product) and stable composite oxides (complex oxide) when these elements are added in film, or above-mentioned element is distributed to the reason such as immersion that rusty stain forms oxyacid ion (oxoacid ion), suppressed the Cl ion that promotes corrosion, obtain the effect of inhibition Corrosion developing (erosion progression).
One or two or more kinds element in Mo, W, Ni, Cu, Mg, V, Co, Sn, Sb can add in film with the form of monomer or compound.P element can add with the form of compound.In addition,, from the result of testing, their total content converts and is less than 0.01g/m with element 2time, sometimes can not fully manifest above-mentioned effect, on the other hand, their total content converts and exceedes 5g/m with element 2time, weldability, cutting etc. are deteriorated sometimes.Therefore, one or two or more kinds element in Mo, W, Ni, Cu, P, Mg, V, Co, Sn, Sb converts preferably at 0.01g/m with element 25g/m above, 2below.In addition, more preferably at 0.1g/m 24g/m above, 2below.
In addition,, as an especially suitable example, film is that resin is as adhesive (alkylsilicate-based binder resin) taking alkyl silicate.
By this method, the inhibition that laser cutting reduces is high, and also can keep admirably elementary rust-preventing characteristic, can also improve the identification of the word of writing with whitewash.
As mentioned above, the film of the present invention that contains the titania powder that laser absorption is high is attached with in laser cutting operation (process) efficient absorption laser light energy, makes the discharge of slag (melted slag) become easy function, in this, be different in itself from the film in the past that has added aluminium powder in the film of zinc powder and zinc powder.In the present invention, owing to being added with the titania powder that laser absorption is high in film, even thereby contain can produce dysgenic zinc powder to laser cutting in the situation that at film, as long as the content of zinc powder is reduced to ormal weight, just can use titania powder efficient absorption laser light energy at the initial stage of laser cutting, thereby obtain having the coated steel of excellent laser cutting.
In addition, aluminium powder and Mo, W, Ni, Cu, P, Mg, V, Co, Sn, Sb especially can not produce the effect in dysgenic situation with raising corrosion resistance to laser cutting.Therefore, by adding again aluminium powder or further add one or two or more kinds element in Mo, W, Ni, Cu, P, Mg, V, Co, Sn, Sb outside above-mentioned titania powder and zinc powder in film, the deteriorated of the corrosion resistance that produces along with the reduction of zinc content can be suppressed, and the characteristic of laser cutting excellence can be maintained.
Based on above reason, in the present invention, arrange on the surface of steel body and contain titania powder and zinc powder, aluminium powder, or further also contain the film (priming paint) of one or two or more kinds element in Mo, W, Ni, Cu, P, Mg, V, Co, Sn, Sb with the form of monomer or compound.
In addition, in the interpolation of coloring pigment, the coloring pigment that is not any kind all can, there is the coloring pigment of following characteristics but use: it is the coloring pigment below 7.0 in order to ensure the lightness that makes Munsell value with the identification of Chinese white, by the black iron oxide pigment taking carbon as main component, black calcined pigment do not form.Therefore, film of the present invention is different from technology in the past and cannot infers the film by technology in the past.
As titania powder, zinc powder, aluminium powder, can use the powder being processed by atomization (atomization technique), mechanical crushing method (mechanical crushing techinique) etc., preferably average grain diameter is controlled at below 15 μ m.These powder can be as required, carries out surface treatment with Al, Zr, polyalcohol (polyol) etc., to improve the dispersiveness in coating.As the coating additive (paint additive) beyond these powder and binder resin, can suitably add as required dispersant (disperser), wetting agent (moistening agent), defoamer (deforming agent), sagging inhibitor (anti-sedimentation), thickener (thickener) etc.
As the monomer of Mo, W, Ni, Cu, Mg, V, Co, Sn, Sb, can use each metal dust.In addition, as Mo, W, Ni, Cu, P, Mg, V, Co, Sn, the compound of Sb, the compound that can form the ion of each element or the oxyacid ion of each element in the aqueous solution is applicable to, for example, can use molybdic acid (molybdic acid), the molybdates (salt of molybdic acid) such as sodium molybdate (sodium molybdate), phosphomolybdic acid (phospho molybdic acid), sodium phosphomolybdate (sodium phosphomolybdate?) etc. phosphomolybdate (molybdate), wolframic acid (tungstic acid), the tungstates (tungstate) such as sodium tungstate (sodium tungstate), phosphotungstic acid (phospho tungstic acid), the phosphotungstates such as sodium phosphotungstate (sodium phospho tungstate), nickelous sulfate (nickel sulfate), the nickel salts such as nickel phosphate (nickel phosphate), the mantoquitas (copper salt) such as copper sulphate (copper sulfate), phosphoric acid (phosphoric acid), the phosphate (phosphate) such as calcium phosphate (calcium phosphate), magnesium nitrate (magnesium nitrate), the magnesium salts (magnesium salt) such as magnesium sulfate (magnesium sulfate), the vanadate (salt of vanadic acid) such as sodium vanadate (sodium vanadate), cobalt nitrate (cobalt nitrate), the cobalt salts (cobalt salt) such as cobaltous sulfate (cobalt sulfate), stannous oxide (stannous oxide), tin ash (stannic oxide), stannous chloride (stannous chloride), the pink salts (stannum salt) such as stannous sulfate (stannous sulfate), antimony oxide (antimony trioxide), antimony pentoxide (antimony pentoxide), the antimonic salts (antimony salt) such as antimony chloride (antimony chloride) etc.
