Flame-retardant sealing door for trains
The invention relates to the technical field of train sealing doors and especially relates to a flame-retardant sealing door for trains. The sealing door comprises a carriage and two door bodies. Eachdoor body comprises a door core frame. Sound insulation layers are bonded to outer walls of two sides of the door core frame. Sound absorption holes which are distributed at equal intervals are arranged in the sound insulation layers; and a heat insulation layer adheres to the outer wall of the other side, away from the door core frame, of the sound insulation layers, a flame-retardant layer adheres to the outer wall of the other side, away from the sound insulation layers, of the heat insulation layer, a steel mesh protection layer adheres to the outer wall of the other side, away from the heat insulation layer, of the flame-retardant layer, and an outer protection layer is welded to the outer wall of the other side, away from the flame-retardant layer, of the steel mesh protective layer. The sealing door has beneficial effects that the flame-retardant layer, the heat insulation layer and the sound insulation layers are combined to serve as an internal structure of a door body so that the door body has flame-retardant and mute effects; and the door body is tightly attached to a carriage door frame under the action of the flame-retardant layer, noise transmission is further reduced, and smoke is prevented from entering the door body.
本发明涉及火车密封门技术领域，具体是一种阻燃式用于火车的密封门，包括车厢和两个门体，门体包括门芯框架，门芯框架的两侧外壁上均粘接有隔音层，且隔音层的内部开设有呈等距离结构分布的吸音孔，隔音层远离门芯框架的另一侧外壁上粘接有隔热层，且隔热层远离隔音层的另一侧外壁上粘接有阻燃层，阻燃层远离隔热层的另一侧外壁上粘接有钢网保护层，且钢网保护层远离阻燃层的另一侧外壁上焊接有外保护层。本发明的有益效果以阻燃层、隔热层和隔音层进行组合作为门体的内部结构，使得门体具有阻燃和静音效果，在阻燃层的作用下，使得门体与车厢门框紧密贴合，进一步降低噪音的传播，避免烟雾进入。
