According to the invention, the high-temperature toxic smoke generated by a fire within a certain period of time cannot be randomly diffused to an evacuation passage of personnel, and meanwhile, the smoke in the isolation area is intensively exhausted, so that the purposes of facilitating safe evacuation of the personnel and reducing fire loss are achieved.

The invention discloses a light and fire-resistant partition door of a metro driver cab. The light and fire-resistant partition door of the metro driver cab comprises a door frame and a door leaf. The door leaf is movably connected with the door frame through hinges and fasteners. The door leaf comprises a framework and core materials. The light and fire-resistant partition door of the metro driver cab is characterized in that the framework is made from aluminum alloy sections; the core materials are aluminum cellular boards; aluminum skins are bonded to the surfaces of the two sides of the core materials correspondingly; a groove is formed in the end face, facing the door frame, of the framework; an expandable graphite rubber strip I is arranged in the groove; an expandable graphite rubber strip II is arranged on a boss at the pressing junction of the door frame and the door leaf; and two layers of ultrathin steel structure fireproof coatings are sprayed on the passenger room side of the door frame and the passenger room side of the door leaf correspondingly. Compared with the prior art, the light and fire-resistant partition door of the metro driver cab has the beneficial effects that the lightweight characteristic is achieved, the weight can be reduced by 80 kg, an excellent structural fire-resistant function is achieved, and the fire-resistant capability can reach 30 min which is far longer than that of a standard requirement.
