A method for manufacturing a metal fiber porous material comprises the following steps:
the method comprises the following steps: a plurality of metal fiber wires are made into a three-dimensional net structure.
Step two: an adhesive is used to bond the contact points of the several metal fiber filaments.
Step three: heating or drying the bonded metal fiber wires with the three-dimensional net structure to solidify the adhesive to form a metal fiber porous material; compared with the traditional high-temperature sintering, the heating or drying is low in temperature, and the toughness of the metal fiber in low-temperature drawing can be kept.
Preferably, the adhesive comprises an organic adhesive and an inorganic adhesive.
Preferably, the adhesive is in a powder form; in the second step, adhesive is sprayed and dispersed at all positions of the metal fiber wires of the three-dimensional net structure; and step three, heating, melting the adhesive, and adhering contact points of a plurality of metal fiber wires to form the metal fiber porous material.
Preferably, in the second step, the metal fiber wires constituting the three-dimensional net structure are immersed in a liquid with an adhesive; the third step is that after being fished up for a period of time, the drying is carried out, the liquid volatilizes or evaporates, and the remaining adhesive adheres to the metal fiber wires to form the metal fiber porous material; the step has less adhesive amount and enough liquid components, and the adhesive shrinks more and more in the evaporation process and finally shrinks to the contact point of the fiber and the fiber for adhesion, thereby keeping the through holes and the air holes of the metal fiber porous material.
Preferably, the adhesive is a latex adhesive or a water-soluble adhesive.
