Plate for normally-closed fireproof door
The invention discloses a plate for a normally-closed fireproof door. The plate comprises a first steel plate surface layer, a second steel plate surface layer, a first heat absorbing layer, a second heat absorbing layer and an asbestos flame retarding layer, wherein the asbestos flame retarding layer is positioned between the first steel plate surface layer and the second steel plate surface layer; the second steel plate surface layer is positioned between the second heat absorbing layer and the asbestos flame retarding layer; and the first steel plate surface layer is positioned between the first heat absorbing layer and the asbestos flame retarding layer. The plate for the normally-closed fireproof door uses the heat absorbing layers for absorbing the heat, so that the temperature of a door sheet rises so as to sense the fire condition beforehand.
