Abstract
A composite foam metal material is composed of a foam metal (A) as skeleton (3-95 wt.%) and another metal (B) (the rest) for compounding. It is prepared through prepring electrically conductive metal layer on the said foam metal (A) by electric deposition, depositing another metal (B), and heat treating. It can be used in secondary battery or as filter, shielding, or accoustical material.
Description
The present invention relates to a kind of foam metal material, especially prepare the method for this foam metal.
At present, along with metal preparation technology's continuous development, foam metal is with its light specific gravity, characteristics such as specific area is big and be widely used in aspects such as filtration, shielding, sound-absorbing and alkaline secondary cell and catalyst carrier.Especially at home make, outward in Ni-MH battery and the nickel-cadmium cell, often use nickel foam to do the electrode base board of battery.Because nickel foam has the tridimensional network that is interconnected, the porosity height, good uniformity, characteristics such as resistivity is low, and pliability is good play carrier and collector in electrode base board.Yet existing foam metal mostly is the simple substance foam metal greatly, so this foam metal will be subjected to the restriction of this kind metallic character, and manufacturing cost is often higher.
The purpose of this invention is to provide a kind of composite foam metal, prepare composite foam metal by a kind of new method, improve the performance of foam metal, and make it have other properties such as corrosion-resistant, high temperature resistant or good conductivity, reduce the manufacturing cost of simple substance foam metal.
Composite foam metal among the present invention is to be framework with a kind of foam metal (A), and at another metal of its surface recombination (B), wherein the component content of foam metal (A) is 3～95% (percentage by weights), and compound another metal (B) is a surplus.
Foam metal in the composite foam metal among the present invention (A) is nickel, iron, copper, lead, zinc, and compound another metal (B) is chromium, nickel, silver.
The porosity of composite foam metal of the present invention is greater than 95%, and the aperture is in 200～500 mu m ranges, and thickness is in 1.5～5.0mm scope.
The method that is used to prepare above-mentioned composite foam metal is: earlier foamed material is prepared conductive layer, adopt the method for electro-deposition, plated metal on foamed material (A) is again at another metal of metal A surface deposition (B), after Overheating Treatment, form composite foam metal.
The above-mentioned method for preparing composite foam metal can also be: foamed material is handled back preparation conductive layer, elder generation's a kind of metal of electro-deposition (A) on foamed material, form a metal frame through Overheating Treatment, again by electro-deposition, at another metal of surface recombination (B) of metal (A), make compound vacuole through Overheating Treatment at last and smear metal.
Said foamed material is polyurethane foam plastics, weaving or nonwoven cloth, fibrofelt etc. in preparation composite foam metal process.
In preparing the method for composite foam metal, the step of foamed material being handled back preparation conductive layer is as follows: 1) preliminary treatment, by improving the wetability and the hydrophily of foamed plastics matrix after oxidation processes and the reduction processing, eliminate blind (closing) hole on the matrix; 2) on pretreated foamed plastics, can adopt other methods such as electroless plating method or coating method and vapour deposition, spraying plating, vacuum plating to prepare conductive layer, make non-conductive foamed plastics have electric conductivity.
In preparing the method for composite foam metal, heat treatment comprises the steps: 1) thermal decomposition, in air, remove organic matter or foamed material matrix by heating, form the foam metal framework, heating-up temperature is at 200～600 ℃; 2) reduction is heat-treated in containing reducing atmosphere, improves the mechanical performance of composite foam metal, and temperature is controlled at minimum 0.55 times of being not less than low-melting-point metal (A or B) fusing point, and the recovery time is controlled at 5～30min.
The performance of the composite foam metal among the present invention is determined by the characteristic (kind) and the different content of two kinds of metals, therefore in preparation process, when carrying out electro-deposition, control the deposition of metal by adjusting current density and sedimentation time, make resulting composite foam metal have properties such as corrosion-resistant, high temperature resistant, low resistance, and can reach the manufacturing cost that reduces foam metal.
Composite foam metal of the present invention can be widely used in the secondary cell, also can be used as materials such as filtration, shielding, sound-absorbing and is applied in each field.
Below by for example composite foam metal of the present invention and preparation method thereof being described further.
