Quantification method of influence of aluminum foil content effect on anti-radiation non-woven material

Abstract

The invention discloses a quantification method of the influence of an aluminum foil content effect on an anti-radiation non-woven material. With the same needling depth, the tensile breaking force ofa needling material is improved along with the reduction of the content proportion of an aluminum foil accounting for a fiber web. When the aluminum foil accounts for 10 percent of the fiber web, thebest tensile breaking performance is obtained. An electromagnetic shielding performance of the needling material is reduced along with the reduction of the content proportion of the aluminum foil accounting for the fiber web, the strength loss rate is reduced along with the reduction of the aluminum foil content, the air permeability is reduced along with the reduction of the aluminum foil content, and when the aluminum foil content is high, the fiber web is less in amount, the material is thin, and a corresponding ventilation effect is better. The quantification method of the influence of the aluminum foil content effect on the anti-radiation non-woven material provided by the invention has the beneficial effects that the method has a definite guiding significance on electromagnetic shielding research and actual process production.

Description

technical field [0001] The invention belongs to the technical field of materials, and relates to acupuncture processing and performance research of radiation-proof non-woven materials. Background technique [0002] Needle-punched non-woven fabrics are consolidated through the flexible entanglement between fibers, thereby generating extrusion force, cohesion force and friction force. It has a special three-dimensional fiber structure, smooth surface and excellent mechanical properties. Needle-punched nonwovens are more and more widely used in the field of life. With the widespread use of electronic devices, the electromagnetic radiation in life is also increasing. The 21st century is a period of rapid development of communication equipment and electronic and electrical equipment such as computers, mobile phones, microwave ovens, Bluetooth technology, wireless networks, etc., and it is also an era of serious electromagnetic radiation pollution. Electromagnetic wave radiation...

Problems solved by technology

[0004] The existing electromagnetic radiation protective clothing has a contradiction between shielding effectiveness and wearing comfort. The airtight protective clothing can obtain high shielding effectiveness, but it is stuffy to wear, which affects the comfort and work efficiency, while the electromagnetic radiation protective clothing of the work clothes style cannot reach high. Shielding effectiveness, protection effect is not ideal

In addition, there are also problems such as the unreasonable design of the clothing structure, which leads to the decrease of the electromagnetic shielding efficiency, the weak conductive layer, which is easy to detach after washing, which leads to the decrease of the shielding effect, and the electromagnetic signals of all frequency bands are shielded, resulting in the interruption of the communication of some working tools such as mobile phones.
