Embodiment

[0066] First, foamed polyurethane was used as a starting material for manufacturing iron foam. The thickness of the foamed polyurethane used was 1.7 mm, and the average diameter of the cells was 575 μm.

[0067] The prepared polyurethane foam is in the state of having undergone basic pretreatment. At this time, nickel-titanium (Ni-Ti) and copper-titanium (Cu-Ti) are deposited by the PVD device installed in the roll-to-roll equipment.

[0068] Therefore, the embodiments of the present invention will be described below in the order of nickel-titanium (Ni-Ti), copper-titanium (Cu-Ti).

[0069] 1. Example of depositing nickel-titanium (Ni-Ti)

Embodiment A1

[0071] Nickel was deposited first followed by titanium on the prepared polyurethane foam.

[0072] In Example A1, the deposition was carried out with a mixing ratio of nickel and titanium of 5:5, and the thickness of the deposited mixed layer of nickel and titanium was 0.17 μm.

[0073] The electroconductive porous body deposited with the above-mentioned nickel and titanium was subjected to iron plating in a plating tank having the composition shown in Table 1.

[0074] When electroplating iron, the electrolytic condition of the electroplating tank is that the current density of the apparent cathode is 700A / m 2 , the temperature and pH of the plating solution are shown in Table 1. The surface density of the electroplated conductive porous body is 420g / m 2 .

[0075] Spray and pickle the electroplated conductive porous body with a hydrochloric acid solution at 60° C. and a pH value of 1 to 1.5, and then spray air to remove the pickling solution. Thereafter, washing was perf...

Embodiment A2

[0081] In Example A2, the deposition was carried out with a mixing ratio of nickel and titanium of 7:3, and the thickness of the deposited mixed layer of nickel and titanium was 0.2 μm.

[0082] The electroconductive porous bodies described above were iron-plated in a plating tank having the composition shown in Table 1.

[0083] When electroplating iron, the electrolytic condition of the electroplating tank is that the current density of the apparent cathode is 500A / m 2 , the temperature and pH of the plating solution are shown in Table 1. The surface density of the electroplated conductive porous body is 418g / m 2 .

[0084] Spray and pickle the electroplated conductive porous body with a hydrochloric acid solution at 60° C. and a pH value of 1 to 1.5, and then spray air to remove the pickling solution. Thereafter, washing was performed by spraying water at 60° C., and water was removed by spraying air. Next, cleaning is performed by spraying 0.5-5 g / L antioxidant (water-so...

Abstract

The invention relates to a manufacturing method of foam iron, and particularly relates to a method for plating iron on a conductive porous body surface by electroplating and producing foam iron through heat treatment. The manufacturing method of foam iron comprises the following steps: i) preparing an organic porous body; ii) depositing metal selected from nickel (Ni) or copper (Cu) on the organic porous body surface, then depositing titanium (Ti) to prepare a conductive porous body; iii) injecting an iron electroplating solution into the conductive porous body to electroplate iron on the conductive porous body surface, wherein the electroplating solution contains ferrous chloride (FeCl3.4H2O), is added with at least one of malonic acid, ammonium chloride (NH4Cl), and vanadium trichloride (VCl3), and has a pH of 0.5-2.5; iv) putting the conductive porous body electroplated with iron in a heat treatment furnace, performing heat treatment to remove components of the organic porous body.

Description

technical field [0001] The invention relates to a foam iron and a manufacturing method thereof, in particular to a method for continuously manufacturing foam iron with excellent ductility and high tensile strength by means of electroplating and the foam iron manufactured by the method. Background technique [0002] Metal foam refers to a porous metal with many bubbles inside the metal material. [0003] This metal foam is classified into an open cell type or a closed cell type according to the shape of the bubbles inside. In the open cells, a plurality of bubbles exist in a connected state, and gas or fluid easily passes through these bubbles. On the contrary, in the closed cells, the air bubbles are not connected to each other and exist independently, so the gas or fluid cannot pass through easily. [0004] As far as metal foam with open cells is concerned, its structure is similar to that of human bone, so the structure is stable, and the surface area ratio per unit volu...
