Problems solved by technology

[0002] At present, in the domestic military electromagnetic shielding fabric materials, the surface of ordinary fabrics is mostly coated with a metal layer, but this type of material is difficult to deal with flame retardancy. To achieve flame retardancy, a large amount of flame retardant must be coated on the surface of the metal , so there are deficiencies in poor adhesion, low flame retardancy and poor resistance to washing

Abstract

The invention belongs to the field of special functional textile materials and particularly relates to electromagnetic shielding flame-retardant cloth and a preparation method thereof. As a flame-retardant liquid, a conductive liquid and the like are applied to fiber cloth, the electromagnetic shielding flame-retardant cloth gains an electromagnetic shielding function and can be charred when in contact with a fire, self-distinguish (within 10 s) when the fire is removed and effectively prevent spreading of flames. Electromagnetic shielding garments or military shielding devices produced with the electromagnetic shielding flame-retardant cloth can provide a shielding function and a flame-retardant protection function.
