Microwave-absorbing electromagnetic-radiation-proof garment

Abstract

The invention discloses a microwave-absorbing electromagnetic-radiation-proof garment, comprising a garment body, wherein the garment body comprises a moisture absorption and perspiration layer, an electromagnetic wave shielding layer, an electromagnetic wave absorbing layer and a water-proof and air permeable layer, wherein the clothes body comprises a moisture absorption and perspiration layer,an electromagnetic wave shielding layer, an electromagnetic wave absorbing layer and a water-proof and air permeable layer. The electromagnetic wave absorbing layer with honeycomb structure can increase the contact area with the electromagnetic wave, and the electromagnetic wave shielding layer with waveform can shield and reflect the electromagnetic wave to the electromagnetic wave absorbing layer for the second absorption. The specific surface area of nano silicon dioxide in microwave absorbing chemical fiber increases, the hanging bonds of grain boundary and grain boundary atoms increase, and the loss of incident electromagnetic wave increases. Acetylene carbon black can reduce the minimum reflectance of nano- silicon dioxide, expand the absorption bandwidth, and increase the electromagnetic radiation protection effect of nano silicon dioxide. Zinc ferrite has the function of absorbing electromagnetic wave. The dielectric constant of expanded perlite is close to that of air, which can make the impedance match between material surface and free space better, reduce the reflectance of material surface, make electromagnetic wave enter into material interior, and give full play to the microwave absorbing performance of zinc ferrite.

Description

technical field [0001] The invention relates to a wave-absorbing anti-electromagnetic radiation clothing. Background technique [0002] While the rapid development of information technology has brought convenience to the world, it is also accompanied by disadvantages—electromagnetic radiation. Electromagnetic radiation, also known as electronic smog, is composed of electric energy and magnetic energy transferred together in space, and the energy is generated by the movement of charges; for example, the moving charges emitted by a radio frequency antenna that is transmitting signals will produce electromagnetic energy. The electromagnetic "spectrum" includes all kinds of electromagnetic radiation, from very low frequency electromagnetic radiation to very high frequency electromagnetic radiation. There are radio waves, microwaves, infrared rays, visible light and ultraviolet light in between. The general definition of the radio frequency portion of the electromagnetic spect...

For this reason, anti-electromagnetic radiation clothing has appeared, but now most anti-electromagnetic radiation clothing uses the principle of reflection to reflect electromagnetic waves or has poor wave-absorbing performance, resulting in weak radiation protection and inconvenient use.
