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.
