The manufacture method > of < aluminium porous insert
As mentioned above, utilize molten salt bath to manufacture according to aluminium porous insert of the present invention by plating method.Specifically, to be made up of polyurethane foam etc. and the resinite with the tridimensional network being provided with communicating aperture (hereinafter, also referred to as " resinite ") as core, electroconductibility is carried out to resinite and gives process, in molten salt bath, then carry out the plating of aluminium.Subsequently, the resin structure obtained its with aluminium film is heat-treated, thus remove resin by burning.Thus, the aluminium porous insert only remaining with metal level has been prepared.
Manufacture method according to aluminium porous insert of the present invention will be described in further detail below.
(there is the preparation of the resinite of tridimensional network)
First, preparation has the resinite of tridimensional network and communicating aperture.The material of any resin as resinite can be chosen.The example of described material comprises the foamed resin be made up of urethane, melamine, polypropylene or polyethylene etc.
Because polyurethane foam and melamine foam have high porosity, hole connectedness and good pyrolytic, thus preferred used as foamed resin.From the homogeneity in hole and the easy aspect such as acquired and from the aspect obtaining the foam with small-bore, polyurethane foam is preferred.
Resinite is usually containing residues such as the whipping agent in foam manufacturing processed and unreacted monomers.Therefore in order to subsequent step, preferably carrying out washing treatment is carried out.Resinite as skeleton defines net in three dimensions, thus defines the hole of connection on the whole.In the cross section that the bearing of trend of the skeleton with polyurethane foam is vertical, this skeleton is essentially trilateral.
The porosity of described foamed resin is preferably 80% to 98%, and aperture is 420 μm to 4,230 μm.
Porosity is defined by following formula:
Porosity=(1-(weight [g]/(volume [cm of porous material of porous material
3] × material density)) × 100 [%]
Determine aperture in the following manner: the surface of being amplified resinite by microphotograph etc., calculate the hole count of per inch (25.4mm) as cell number, then calculate mean pore size by following equation: mean pore size=25.4mm/ cell number.
(electroconductibility on resinite surface is given)
In order to make the surface of resinite be covered by aluminium by plating, in advance electroconductibility being carried out to the surface of resinite and giving process.Give process to electroconductibility to have no particular limits, as long as the layer with electroconductibility can be arranged by this process on the surface of resinite.Any means can be selected, vapour deposition or the sputtering of the electroless plating, aluminium etc. of the conductive metal such as such as nickel or be coated with the conductive coating paint containing conductive particles such as carbon granules.
Give the example of process as electroconductibility, the sputtering technology implementing aluminium will be described through below and give the method for electroconductibility and given the method for electroconductibility by use carbon granule as conductive particle to the surface of resinite.
The sputtering of aluminium
To using the sputter process of aluminium to have no particular limits, as long as aluminium is used as target, can sputter according to conventional methods.Such as, resinite is fixed on substrate holder, then, while introducing rare gas element, between support and target (aluminium), applies volts DS.Make the rare gas element of ionization clash into aluminium thus, and the aluminum particulate of sputtering is deposited on the surface of resinite, thus forms the sputtered film be made up of aluminium.Sputter process is carried out preferably can not there is the temperature of melting at resinite under, specifically, carries out at the temperature of 200 DEG C, preferably at about 100 DEG C at about 120 DEG C to the temperature of 180 DEG C.
Carbon is coated with
First, the carbon coating as conductive coating paint is prepared.Suspension as conductive coating paint preferably contains carbon granule, binding agent, dispersion agent and dispersion medium.In order to applying conductive particle equably, need to make suspension keep the state of even suspension.For this reason, suspension preferably remains on 20 DEG C to 40 DEG C.This is because when the temperature of suspension is lower than 20 DEG C, uniform suspended state is destroyed, only there is binding agent can concentrate on the surface of the skeleton of the network structure forming resin porous insert, thus form adhesive layer.In this case, the carbon granule layer be coated with is easy to peel off, and is difficult to form the metal plating of firm attachment to carbon granule layer.On the other hand, when the temperature of suspension is more than 40 DEG C, the steam output of dispersion agent increases.Therefore, along with the prolongation of coating processing time, suspension concentrates, and the glue spread of carbon is tending towards changing.The particle diameter of carbon granule is preferably 0.01 μm to 5 μm, more preferably 0.01 μm to 2 μm.When particle diameter is excessive, carbon granule may block the cell of resinite, is unfavorable for level and smooth plating.When particle diameter is too small, be difficult to guarantee enough electroconductibility.
By target resinite is immersed in suspension, and carry out extruding and drying, thus carbon granule can be applied on resinite.
(formation of the aluminium film on resinite surface)
Adopt and use the plating method of molten salt bath as the method forming aluminium film at resinite on the surface.
Melting salt plating
Carry out electroplating thus form aluminium film on the surface of resinite in melting salt.
By aluminizing in molten salt bath, especially the aluminium film had compared with heavy thickness can be formed uniformly on the surface of complicated skeleton structure (as there is the resinite of tridimensional network).In melting salt, surface has been given the resinite of electroconductibility as negative electrode, aluminium, as anode, applies direct current between both.
Melting salt can be the organic melting salt as the eutectic salts be made up of Organohalogen compounds and aluminum halide, or as the inorganic molten salt of the eutectic salts be made up of alkali metal halide and aluminum halide.When being used in organic molten salt bath of melting at relatively low temperature, can electroplate in as the Undec situation of resin molded body of base material.As Organohalogen compounds, imidazole salts or pyridinium salt etc. can be used.Specifically, preferred 1-ethyl-3-methylimidazolium chloride (EMIC) and butyl pyridinium chloride (BPC).
The deterioration of melting salt can be caused when water or oxygen are mixed in melting salt.Therefore preferably in sealed environment, plating is carried out under the such as inert gas atmosphere such as nitrogen or argon.
As molten salt bath, preferably nitrogenous molten salt bath.In these baths, preferably use imidazoles salt bath.When the salt of at high temperature melting is used as melting salt, the dissolving of resin in melting salt or rate of decomposition are greater than the growth velocity of plated film, thus cannot form plated film on the surface at resinite.Even and if imidazoles salt bath also can use at relatively low temperatures, and resin can not be affected.As imidazole salts, preferably use the salt containing having the glyoxaline cation of alkyl 1 and 3 places.Particularly, aluminum chloride-1-ethyl-3-methylimidazolium chloride (AlCl
3-EMIC) melting salt because of its high stability and be difficult to decompose but most preferred.By using molten salt bath thus carry out plating on urethane resin foam or melamine resin foam.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 the reduction of molten salt bath temperature, the current density range for plating narrows, thus is difficult to the whole surface of plated resin body.When the temperature of molten salt bath is the high temperature more than 100 DEG C, then the shape being used as the resinite of base material is easily deformable.By above-mentioned steps, prepare and comprised the aluminium-resin structure of resinite as the core of skeleton.
(removal of resin)
In nitrogen atmosphere, air etc., more than 500 DEG C, heat the aluminium-resin structure of above-mentioned preparation thus it is heat-treated.Thus, eliminate resin by burning, thus obtain aluminium porous insert.Having been found that to prepare aluminium porous insert of the present invention, effectively improvement being added to this step of carrying out before this always.Specifically, method as described below is adopted.

In order to obtain by the method the aluminium porous insert that Skeleton Table mask has micro concavo-convex, be preferably 10mL/m in the amount of the water being attached to resin structure
2to 1,000mL/m

2to 1,000mL/m
2, be also more preferably 500mL/m
2to 1,000mL/m
2.
-the removal resin that burns from resin structure-
Except above-mentioned two kinds of methods, also has a kind of method on the surface for the preparation of skeleton with the aluminium porous insert of micro concavo-convex.Specifically, even if when plating solution is fully drained and the water of attachment is also fully removed by follow-up washing process, still can carry out burning in the atmosphere (namely there is the atmosphere of high dew point) containing a large amount of water and remove the subsequent step of resin.For this reason, such as can heat-treat by being heated to more than 500 DEG C and supplying malaria simultaneously.Equally in this case, it is believed that at about 80 DEG C, react to each other at the water carrying out supplying in this heat treated atmosphere and aluminium and generate boehmite, then boehmite is converted into the gama-alumina with micropore by heating further.
In order to obtain by the method the aluminium porous insert that Skeleton Table mask has micro concavo-convex, in the burning removal step of resin, the dew-point temperature of atmosphere is preferably 0 DEG C to 60 DEG C.Dew-point temperature is more preferably 20 DEG C to 60 DEG C, is also more preferably 40 DEG C to 60 DEG C.
