Description
Technical Field
The invention relates to the technical field of electromagnetic shielding materials, in particular to a production process of a graphene-based composite fiber fabric.
Background
With the rapid development and application of electromagnetic pulse weapons (nuclear electromagnetic pulses, high-power microwave weapons, electromagnetic bombs, etc.), the command communication system in future war will face more and more complicated electromagnetic environment. The intense electromagnetic radiation generated by an electromagnetic pulse weapon will seriously interfere with and destroy the normal operation of the command communication system, even leading to complete breakdown of the system. Therefore, important command protection engineering of our army all takes electromagnetic protection measures, prevents the interference and the damage of electromagnetic pulse, and ensures the safety of the command communication system.
The base material selected by the electromagnetic shielding fabric is mainly terylene, aramid, carbon fiber and the like, and the terylene is the most. The electromagnetic shielding fabric is mainly realized in a metal fiber blending mode, a metal coating mode, a vacuum plating mode, a chemical plating mode, an electroplating mode and the like, wherein chemical plating is most commonly used. The plating method mainly includes silver, copper, nickel, tin and their composite plating, and the most of them is copper plating and silver plating.
The metal fiber is blended, namely the metal fiber and the nonmetal fiber are mixed and interwoven for spinning and weaving, the metal fiber participating in the blending mainly comprises copper, nickel, aluminum, stainless steel or other alloys, and the nonmetal fiber comprises common natural fiber such as cotton fiber and most of chemical fiber such as terylene, chinlon and the like. Researches show that the electromagnetic shielding effect of the metal fiber in the fabric is correspondingly enhanced along with the increase of the specific gravity of the metal fiber, but the mechanical properties of the metal fiber, such as tensile strength, tearing strength, bursting strength and the like, are slightly reduced. Because the metal fiber has larger mass, the metal fiber is easy to bend and tangle in the weaving and finishing processes, the bending rigidity of the fiber is poor, the obtained fabric is thicker and heavier and has stiff hand feeling, and the difference of the shielding effect of the electromagnetic shielding fabric prepared by the method in different frequency ranges is larger.
The surface is plated with metal shielding fabric, and the fabric material is formed by attaching a conductive layer on the surface of the fabric and achieves the purpose of shielding mainly through reflection loss. Common fabrication techniques include chemical plating, electroplating, vacuum plating, magnetron sputtering plating (plasma plating), and the like.
The existing electromagnetic shielding fabric still cannot get rid of the use of metal, inevitably brings the defects of hard texture, inconvenient processing, overlarge weight, poor serviceability and the like, and is difficult to meet the requirements of pursuing lighter, thinner, stronger and wider electromagnetic shielding tents.
For the development of the blending technology, the metal wires and the fiber yarns are mainly plied according to different proportions, the density of the yarns and the types of the plied yarns are changed, and the electromagnetic shielding effect is achieved, but the problems of the domestic technical equipment precision, the winding problem of the superfine metal fibers in the weaving process, the easy breakage of the metal fibers and the like are not solved, so that the shielding performance of the product produced by adopting the technology at present is relatively poor.
