As the manufacture method of above-mentioned aluminium porous insert, present applicant has proposed and utilize aluminium to carry out electric plating method (having announced Japanese Patent Application Laid-Open 2012-007233 (patent documentation 2)) to the resin molded body with tridimensional network.Conventional aluminium molten salt bath must be heated to high temperature.Therefore, when the surface of resin molded body is by electroplated aluminum, a problem is in this case: resin cannot be resisted high temperature thus can melting.But, according to the method described in patent documentation 2, the organic chloride salt of 1-ethyl-3-methylimidazolium chloride (EMIC) or 1-butyl pyridinium chloride (BPC) and so on and aluminum chloride (AlCl
3) mix the aluminium bath that formed at room temperature for liquid, thus make it possible to electroplate resin molded body with aluminium.Especially, EMIC-AlCl
3system has good characteristics of liquids, and therefore it can be used as aluminium plating solution.
At above-mentioned aluminum-plated steel strip and have in the aluminium porous insert of tridimensional network, in order to obtain the surface the thickness increasing aluminium coat with excellent gloss, need to aluminize to the matrix with aluminium surface further.
But as mentioned above, aluminium is formed with oxide film on the surface.Therefore, though for by Aliminuium electrodeposition to aluminium on the surface, also cannot power to this surface uniform.Therefore, there will be the problem that plating shape is island.

Embodiment
Device of aluminizing of the present invention is for by transfer matrix thus by Aliminuium electrodeposition to the device of aluminizing on this matrix in coating bath.This device has following feature:
Upstream side on the delivery direction of above-mentioned matrix, above-mentioned coating bath is divided into the first tank room and the second tank room successively by division plate;
In above-mentioned first tank room being provided with negative pole, this negative pole is electrically connected with above-mentioned matrix in the mode making above-mentioned matrix and serve as positive pole; And
In above-mentioned second tank room being provided with positive pole, this positive pole is electrically connected with above-mentioned matrix in the mode making above-mentioned matrix and serve as negative pole.
Above-mentioned matrix is had no particular limits.But, when matrix be routine aluminize device cannot thereon well electric deposition aluminum (such as, there is the metal of metal oxide film (passive film) on the surface), show excellent effect.The type of aforementioned substrates comprises steel band (steel plate), has the aluminium porous insert of tridimensional network, SUS plate, Cu or Cu alloy sheets, Zn or Zn alloy sheets.
Above-mentioned coating bath accommodates plating solution.Plating solution is had no particular limits, as long as this plating solution has the composition that can carry out electroplated aluminum.The avidity of aluminium to oxygen is high, and its current potential is lower than the current potential of hydrogen.Therefore, be difficult to electroplate in the plating bath of water solution system, because being employed herein molten salt bath.Advantageously can use the molten salt bath formed primarily of aluminum chloride.
About melting salt, organic melting salt of the eutectic salts form be made up of Organohalogen compounds and aluminum halide can be used, and the inorganic molten salt of the eutectic salts form be made up of alkali metal halide and aluminum halide.When being used in organic molten salt bath of melting under relatively lower temp, can carry out plating and the resin molded body as matrix can not be made to decompose, this be favourable.About Organohalogen compounds, imidazole salts, pyridinium salt etc. can be used.More specifically, preferably 1-ethyl-3-methylimidazolium chloride (EMIC) and butyl pyridinium chloride (BPC).
When moisture or oxygen invade in melting salt, melting salt can deterioration.Therefore, advantageously not only in nitrogen, argon gas or other inert gas atmospheres and in enclosed environment, plating is carried out.
About molten salt bath, the melting salt containing nitrogen is favourable.When use there is tridimensional network resin molded body as above-mentioned matrix time, if use the salt of at high temperature melting as melting salt, then the dissolving of resin in melting salt or decomposition rate faster than the speed of growth of coating.Therefore, coating cannot be formed on the surface of resin molded body.In this case, imidazoles salt bath can advantageously be used.Even if also imidazoles salt bath can be used at relatively low temperature, and can not impact resin.
As imidazole salts, the salt containing having the glyoxaline cation of alkyl in 1 and 3 positions advantageously can be used.Especially, aluminum chloride-1-ethyl-3-methylimidazolium chloride (AlCl is most preferably used
3-EMIC) be melting salt, this is because this salt-stable is high, be therefore comparatively not easy to decompose.Plating can be carried out on urethane resin foam, melamine resin foam etc.The temperature of molten salt bath is 10 DEG C to 100 DEG C, is preferably 25 DEG C to 45 DEG C.Along with described temperature is down to low temperature, the current density range that can carry out plating narrows, and is therefore difficult to carry out plating on all surfaces of resin molded body.High temperature more than 100 DEG C trends towards the problem producing the shape damaging the resin being used as matrix.
When use has dystectic matrix (as steel band), inorganic salt bath also can be used as melting salt.Inorganic salt bath is generally AlCl
3the two-pack of – XCl (X: basic metal) or the salt of multicomponent system.The melt temperature of aforementioned inorganic salt bath is usually above organic salt bath (as imidazoles salt bath), but the less-restrictive of envrionment conditions (as humidity and oxygen), therefore make practical application cost on the whole lower.
In order to improve smoothness and the glossiness of the aluminium plated film be formed on matrix surface, additive can be added, as dimethylbenzene, benzene, toluene and 1,10-phenanthroline.
Particularly, 1,10-phenanthroline can advantageously be used.Preferably, the addition of above-mentioned additive is 0.25g/L to 7g/L.When addition is more than 0.25g/L, enough level and smooth aluminium plated film can be obtained.When addition is below 7g/L, the reduction of plating efficiencies can be suppressed.
Below, by suitably with reference to the elaboration that accompanying drawing carries out specifically to the present invention.
Fig. 1 illustrates that the present invention aluminizes the structure example of device.As shown in Figure 1, aluminize in device of the present invention, by division plate 103, the coating bath 102 containing plating solution is divided into the first tank room 104 and the second tank room 105.Continuously matrix 101 is sent to the second tank room 105 by the first tank room 104.
Arrange division plate 103 with by the first tank room 104 and the second tank room 105 electrically separated.Advantageously can use the division plate of insulation.Such as, Teflon (registered trademark), pottery, glass, superengineering plastics can be used as polyether-ether-ketone (PEEK) and thermotolerance vinyl chloride resin.
Division plate 103 be provided with matrix by mouth (passing aperture).Advantageously, the minimum possibility size that matrix only can be made to pass through should be had by mouthpiece.Such as, advantageously, matrix is slit-shaped by mouth.
First matrix 101 is transferred into the first tank room 104, and this first tank room 104 is provided with negative pole 107, and it is electrically connected in the mode of the positive pole making matrix 101 and serve as in the first tank room 104.This being formed between negative pole 107 and matrix 101 produces electrolysis.Therefore, the metal oxide film be formed on matrix 101 surface is removed by electrolysis, thus the metallic surface of formation matrix 101 is come out.
Anticathode 107 has no particular limits.Such as, aluminium, titanium and copper can advantageously be used.
As an example, Fig. 1 illustrates the situation being provided with two negative poles 107: a negative pole 107 is positioned at above matrix 101, and another negative pole 107 is positioned at below matrix 101.But the number of anticathode 107 has no particular limits.An electrode, three electrodes or more electrode can be adopted.The position being provided with negative pole 107 is had no particular limits.But, advantageously, negative pole 107 is arranged at the position that distance matrix 101 is near as far as possible, so that effectively electrolysis can be carried out.
In order to make matrix 101 serve as positive pole in the first tank room 104, the power supply positive terminal be connected with negative pole 107 is connected with matrix 101.In this case, in order to effectively carry out electrolysis, advantageously, matrix 101 is connected with positive pole at the upstream side near the first tank room 104 entrance.
Fig. 1 shows such situation: wherein, and the upstream side of the ingress of the first tank room 104 is provided with the first power supply roller 106, and this first power supply roller 106 is connected with the positive pole of power supply.By adopting this formation, continuously while transfer matrix 101 by the first power supply roller 106 and the first transfer roller 110, applying voltage by the first power supply roller 106 to matrix 101, thus making matrix 101 serve as positive pole in the first tank room 104.In situation illustrated in fig. 1, the first transfer roller 110 is arranged at the offside of the first power supply roller 106.But, the power supply roller that is connected with positive pole can be set to replace the first transfer roller 110.
Can according to the amount of the oxide film be formed on matrix 101 suitably to regulate in the first tank room 104 want electrolysis to remove the amount of metal oxide film.Such as, when matrix is made of aluminum, deposition or the meltage of aluminium can be regulated based on following equation:
Meltage [g]=0.3352 × I [A] × t [Hr] (equation) of the deposition/aluminium of aluminium
In above-mentioned equation, " " represent current value, " t " represents the time to I.Constant 0.3352 is constant specific to aluminium, and when matrix is made up of other metals, this constant can be changed into the peculiar constant of this metal to calculate.
Next, the matrix 101 having removed metal oxide film is as mentioned above sent to the second tank room 105 by the slit be formed in division plate 103.Second tank room 105 is provided with positive pole 109, and it is electrically connected in the mode making matrix 101 serve as negative pole in the second tank room 105.This being formed between positive pole 109 and matrix 101 produces electrolysis.Consequently, Aliminuium electrodeposition is on the surface of matrix 101.
As mentioned above, in the first tank room 104, the metal oxide film that matrix 101 is formed on the surface is eliminated.Thus, in the second tank room 105, uniform aluminium coat can be formed on the surface of matrix 101.
Positive pole 109 is had no particular limits.Such as, aluminium, titanium and copper can advantageously be used.
The same with the situation of negative pole 107, as an example, Fig. 1 shows the situation being provided with two positive poles 109: a positive pole 109 is arranged at the top of matrix 101, and another positive pole 109 is arranged at the below of matrix 101.But, the number of positive pole 109 is had no particular limits.An electrode, three electrodes or more electrode can be adopted.The position being provided with positive pole 109 is had no particular limits.But, advantageously, positive pole 109 is arranged at the position that distance matrix 101 is near as far as possible, so that effectively electrolysis can be carried out.
In order to make matrix 101 serve as negative pole in the second tank room 105, the negative terminal of the power supply be connected with positive pole 109 is connected with matrix 101.In this case, in order to effectively carry out electrolysis, advantageously, matrix 101 is connected with negative pole in the downstream side near the second tank room 105 exit.
Fig. 1 shows the second power supply roller 108 and is arranged at the outlet downstream side of the second tank room 105 and situation about being connected with power cathode.By adopting this formation, coming continuously while transfer matrix 101 by the second power supply roller 108 and the second transfer roller 111, apply voltage by the second power supply roller 108 to matrix 101, matrix 101 serves as negative pole in the second tank room 105 thus.Fig. 1 shows the situation that the second transfer roller 111 is arranged at the offside of the second power supply roller 108.But, the power supply roller that is connected with negative pole can be set to replace the second transfer roller 111.
By using above-mentioned equation to calculate the al deposition amount in the second tank room 105.Therefore, current value and time can be regulated like this, be electrically deposited on the surface of matrix 101 to make the aluminium of aequum.Transfer rate by changing matrix 101 carrys out regulating time.
As mentioned above, the device of aluminizing of the application of the invention, even if when being formed with the metal oxide film etc. of insulativity or poorly conductive on matrix surface, also can form aluminium coat well on the surface of this matrix.
When the matrix that the sheet material being steel band and be made up of the resin molded body with tridimensional network is isometric is aluminized, use device of aluminizing of the present invention can pass through improve linear velocity thus effectively produce product.
When the routine of being furnished with a coating bath aluminizes device, when attempting by improving linear velocity thus promoting throughput, the length increasing positive pole can be considered.Such as, when vertically carrying out plating, coating bath is deepened; And when flatly carrying out plating, then coating bath is lengthened.But, in fact, the positive pole limited length of effective plating can be carried out.More specifically, although carry out plating in the position near conductive rollers with high current density, do not carry out plating in the position away from conduction rod.Therefore, in the device being furnished with a coating bath, the increase of linear velocity is limited, therefore cannot promote throughput.
Based on this reason, the coating bath by there is two or more groove can be considered thus raising linear velocity.But, even if when installing two or more conventional plater to carry out operate continuously in the mode of series connection, be easy in the situation of the metal (as aluminium) forming oxide film from the teeth outwards, then there is such problem, that is: can not aluminize to the film formed in the coating bath of position before well.More specifically, the space place between coating bath can form oxide film on the surface of aluminium.When forming oxide film, aluminium deposits with island.In other words, plating cannot be carried out well.Even if the space between coating bath is full of N
2or during other inert atmospheres, also cannot remove deoxidation completely, oxygen can remain with the magnitude of ppm.Even if when aluminium is exposed to the oxygen of above-mentioned small quantity, also oxide film (passive film) can be formed on aluminum surfaces.
In order to avoid producing the problems referred to above, device of aluminizing of the present invention can remove the oxide film be formed on aluminium surface in the first tank room.Therefore, when along matrix delivery direction with the mode of series connection arrange two or more aluminize device time, second and coating bath subsequently also can form level and smooth high-quality Al coating.By using such device of aluminizing, can improve the linear velocity of matrix, thus improve the production efficiency of product, wherein aluminize in device described, the delivery direction along matrix arranges two or more above-mentioned device of aluminizing in the mode of series connection.Because aforementioned device of aluminizing being aluminized continuously by using multiple device of aluminizing, therefore only needing a set of attendant equipment (as the feed mechanism of matrix and spooler), thus significantly reducing the infusion of financial resources to equipment.
The quantity of the aluminium device arranged in a series arrangement is had no particular limits.Suitably its quantity can be selected according to object (thickness of the aluminium coat that such as, be formed).Such as, when use there is tridimensional network resin molded body as matrix time, the device of aluminizing arranging about 2 to 20 can manufacture aluminium porous insert effectively.
When being used as matrix through the resin molded body with tridimensional network of (such as) carbon applying conductive process, the anterior position place that can state device of aluminizing on the invention arranges routine and to aluminize device, and described anterior position is the upstream-most position on matrix delivery direction.To aluminize device about this routine, advantageously can use following device of aluminizing.As shown in Figure 2, aluminize device by making matrix 101 by coating bath 202 thus by Aliminuium electrodeposition to matrix, the feature of this device of aluminizing is: in coating bath 202, is arranged at positive pole 209 in coating bath 202 and is electrically connected with above-mentioned matrix 101 in the mode making above-mentioned matrix 101 and serve as negative pole.
In other words, device of aluminizing of the present invention has following device of aluminizing:
This device of aluminizing is positioned at the anterior position of above-mentioned device of aluminizing, and described anterior position is the upstream-most position on above-mentioned matrix delivery direction;
