Abstract

The invention discloses a composite explosion door with an electromagnetic shielding function. The composite explosion door comprises an electromagnetic shielding modified resin-based composite outer door plate, a light anti-fragment interlayer, an explosion relief layer and an electromagnetic shielding modified resin-based composite inner door plate which are sequentially arranged from outside to inside. Each of the electromagnetic shielding modified resin-based composite outer door plate and the electromagnetic shielding modified resin-based composite inner door plate comprises an electromagnetic shielding composite explosion-proof inner core and an electromagnetic shielding coating; and the electromagnetic shielding composite explosion-proof inner core is formed by pressing a block-shaped molding compound and a multi-layer composite copper net. The composite explosion door with the electromagnetic shielding function is simple in preparation process, raw materials are easy to obtain, less waste is discharged in the preparation process, and the composite explosion door is suitable for large-scale production in factories; the electromagnetic shielding coating has an excellent electromagnetic shielding effect, is not easy to fall off in a use process, and is relatively long in service life; the door body is light in weight, has high impact resistance, and can effectively prevent the penetration effect of high-speed fragments on the door body.

Description

technical field [0001] The invention relates to a composite explosion-proof door with electromagnetic shielding function, which belongs to the safety field of civil air defense engineering. Background technique [0002] Blast-proof door is a kind of anti-blast protection equipment that can resist the explosion shock under certain conditions, dissipate the shock wave pressure generated by the explosion, absorb the impact kinetic energy of fragments, prevent penetration, and effectively prevent the explosion hazard from continuing to be affected by the blast wave. Explosion-proof doors are widely used in command rooms, civil air defense projects, explosives warehouses, inflammable warehouses, workshops, mines and other places. Especially the explosion-proof doors used in civil air defense projects can effectively resist and stop the shock waves and fragments generated by the explosion, and protect people's lives and property. [0003] Electromagnetic wave radiation, also know...
