The anti- virus flame-retardant electromagnetic shielding composite material is sequentially prepared from a low-frequency shielding layer, a barrier layer and a low-high-frequency shielding layer from outside to inside, wherein all layers are sequentially connected together through adhesives; the low-frequency shielding layer is prepared from flame-retardant metal fiber blended fabric; the barrier layer is prepared from at least one of PA (Polyamide), PET (Polyethylene Terephthalate) or EVOH (Ethylene-Vinyl Alcohol Copolymer); the low-high-frequency shielding layer is prepared from copper-nickel coating fabric. According to the anti-gas flame-retardant electromagnetic shielding composite material disclosed by the invention, the gram weight per square meter is 100 to 700 g / m<2>, the protection time on mustard gas is up to 72 hours or more, the electromagnetic shielding performance within a frequency band of 200 MHz to 40 GHz can be up to 70 dB or more, the shielding performance of the low-frequency within a frequency band of 100 KHz to 20 MHz can be up to 20 dB or more, the afterflame time is less than or equal to 10 seconds, and the smoldering time is less than or equal to 10 seconds. The product which is prepared by adopting the anti-gas flame-retardant electromagnetic shielding composite material integrates biochemical protection, electromagnetic shielding and flame retardancy into a whole, and can more meet cutting-edge requirements in military and the like.
