The invention provides a fireproof door of an exit passageway. The fireproof door comprises a door plate and a perlite fireproof layer. The fireproof door is characterized by also comprising an electromagnetic lock, a storage battery, a dry powder block, a switch button, a cable connection wire, a vermiculite plate and a convex groove, wherein the door plate is provided with the convex groove. The convex slot of the door plate is internally provided with the dry powder block, when outside fire intensity is overhigh and the fireproof door is burnt out, the dry powder block falls out, so that a certain fire extinguishment effect is achieved and fire spreading can be temporarily restrained. Two types of fireproof plates, namely the perlite fireproof layer and the vermiculite plate, are arranged in the fireproof door, so that the fireproof capability of the fireproof door is improved; when the fireproof door is tightly closed and a power supply is disconnected, if indoor people need to escape, escape people can press the switch button, the switch button is connected with the storage battery so as to begin supplying power to the fireproof door, so that the escape people can escape conveniently.
