Abstract

The invention provides a preparation method for an iron-nickel-copper oxysome long fiber pipe. According to the technical solution, the preparation method comprises the steps of polypropylene fiber surface treatment, polypropylene fiber chemical copper plating, fiber nickel plating, fiber iron plating, polypropylene fiber removing and long fiber metal composite pipe roasting oxidation, so that the iron-nickel-copper oxysome long fiber pipe is prepared. By means of the preparation method for the iron-nickel-copper oxysome long fiber pipe, iron-nickel-copper oxysome long fiber pipes with different specifications and section shapes can be prepared, the attenuation effect of electromagnetic waves is enhanced through the reflection and absorption effects of residual carbon in the long fiber pipe, and compared with a traditional preparation method, the overlong iron-nickel-copper oxysome fiber pipe can be prepared.

Description

technical field [0001] The invention relates to the technical field of preparation of functionalized metal fiber tubes, in particular to a method for preparing iron-nickel-cuprite long fiber tubes. Background technique [0002] With the rapid development of microwave and microelectronic engineering technology, the importance of advanced microwave-absorbing materials in the fields of anti-electromagnetic interference and stealth technology has become increasingly prominent. Due to its shape anisotropy and magnetic anisotropy, the magnetic fiber tube absorber can obtain high magnetic permeability in the direction of the long axis, and can get rid of the limitation of effective magnetic permeability by isotropic powder materials, so it can be used in the space In a relatively small case, a higher magnetic permeability is obtained, which is beneficial to reduce the weight of the coating and widen the frequency band for electromagnetic wave absorption. Therefore, following the m...
