preparation example Construction

[0050] The steps of a preparation method (method 1) of the above-mentioned flexible porous metal foil 100 include: (1) configuring the raw material powder constituting its metal porous material into a viscous suspension with a dispersant and a binding agent; (2) ) inject the suspension into the molding cavity of the film-making tooling and make it dry to form a homogeneous membrane; (3) put the membrane into the sintering tooling that conforms to the shape of the membrane and then Constrained sintering is carried out, and the flexible porous metal foil 100 is obtained after sintering and taken out from the sintering tool.

[0051] In the above method, the dispersant can use ethanol, methyl ethyl ketone, toluene and other organic solvents with low surface tension and quick volatilization and easy drying; the binding agent can use PVB, PVA, PVC, polyvinyl alcohol, polyethylene glycol (low molecular wax) ), paraffin, fatty acids, aliphatic amides and esters, etc.

Abstract

The invention discloses a preparation method of a porous metal foil. The porous metal foil is a thin sheet manufactured from metal porous materials. The method comprises the steps of (1) preparing raw powder for preparing the metal porous material into thick suspension through a dispersing agent and adhesive; (2) pouring the suspension into a forming die cavity of a file preparing tool, and drying to form a homogenized film; (3) pressing the film to improve the accumulation density of powder particles in the film; (4) sintering the pressed film to obtain the porous metal foil. According to the method, the pressing can improve the accumulation density of the powder particle in the film, and the average diameter of the flexible porous metal foil can reduced and uniform; the pressing pressure can be selected to control the average diameter of the flexible porous metal foil.
