Abstract

The invention relates to a shielding textile integrating high fire resistance, high electric conduction and high magnetic permeability. A preparation method of the shielding textile integrating high fire resistance, high electric conduction and high magnetic permeability comprises the following steps of: injecting fire resistant factors into textile fibers comprising nylon, terylene and chinlon textile fibers to form fire resistant textile fibers, wherein the fire resistant factors comprise the following materials and chemical components in percentage by weight: 5-10 percent of nano imvite NaXAl2[Si4O10(OH)2nH2O], 3-8 percent of red phosphorus master batch (RP) and 3-6 percent of nano antimonous oxide (Sb2O3); mixing carbonyl iron Fe(CO)5 and nickel carbonyl Ni(CO)4 according to a certain proportion by adopting a carbonyl chemical vapor deposition method; and carrying out vapor deposition at 400 DEG C under the protection of inert gas N2 to form a high electric conduction and high magnetic permeability magnetic film on fiber cloth so as to obtain the high fire resistance, high electric conduction and high magnetic permeability shielding textile. The invention is suitable for the field of electromagnetic shielding and is particularly suitable for microwave shielding occasions and power frequency magnetic field shielding occasions.

Description

technical field [0001] The invention relates to a shielding functional fabric with high flame retardancy, high electrical conductivity and high magnetic permeability, which belongs to the technical field of special functional materials. Background technique [0002] With the rapid development of electronic science, products such as mobile phones, microwave ovens, induction cookers, computers, copiers, televisions, air conditioners, and medical nuclear magnetic resonance instruments have entered homes, offices, and hospitals. These electronic products will generate different wavelengths during use. Electromagnetic radiation floods the entire space and is hard to guard against. It has become the fourth largest pollution after air pollution, water pollution and noise pollution, posing a threat to people's living environment. Therefore, it is urgent to study high-performance electromagnetic shielding fabrics. [0003] From the perspective of existing technology and market produ...
