Metal fiber porous material and preparation method thereof

Abstract

The invention provides a metal fiber porous material. The metal fiber porous material comprises a three-dimensional net-shaped structure formed by multiple metal fibers. The positions of contact points of the multiple metal fibers are bonded and fixed through an adhesive. The invention also provides a preparation method for preparing the metal fiber porous material. The preparation method comprises the following steps that firstly, the multiple metal fibers are prepared into the three-dimensional net-shaped structure; secondly, the contact points of the multiple metal fibers are bonded by using the adhesive; and thirdly, after the bonded metal fibers of the three-dimensional net-shaped structure are heated or dried, the adhesive is cured to form the metal fiber porous material. The metal fiber porous material and the preparation method thereof have the beneficial effects that requirements for machines are not high, a large quantity of funds do not need to be spent on purchasing, procedures are few, and the preparation cost is effectively reduced; and the prepared metal fiber porous material also retains obdurability of low-temperature drawing of the metal fibers, and is good in use effect in a high-pressure state and good in durability.

Description

technical field [0001] The invention relates to a metal fiber porous material and a manufacturing method thereof. Background technique [0002] Compared with non-metallic filter materials, metal fiber porous materials have higher strength. With the advancement of science and technology, metal filter materials have been widely used in biological research, pharmaceuticals, environmental protection and other industries; existing The metal filter materials are all made by metal powder metallurgy method, and the vacuum sintering process is annealed, resulting in no elasticity of the material, low toughness, that is, brittleness, poor ductility / toughness; and metal fiber porous materials need to be used under high pressure for a long time If it is used under the condition of low toughness, it is easy to damage its structure, resulting in the disadvantages of reduced performance and low durability; in addition, the cost of vacuum sintering machines is high, and there are many proce...
