Novel fireproof flame-retardant door
The invention discloses a novel fireproof flame-retardant door. The novel fireproof flame-retardant door comprises a door frame, wherein the inner wall of the door frame is fixedly connected with a concentric-square-shaped limiting ring, the inner wall of the door frame is rotationally connected with a door body through spring hinges, a cavity is formed in the door body, and the inner wall of the cavity is fixedly connected with a partition plate; melamine foam layers are fixedly connected to the front face and the back face of the partition plate correspondingly, a plurality of protrusions are fixedly connected to one sides, away from the partition plate, of the melamine foam layers, and a plurality of conical funnel holes extending to the inner wall of the cavity are formed in the front face and the back face of the door frame. According to the novel fireproof flame-retardant door, the conical funnel holes, the protrusions and the melamine foam layers are arranged, and the melamine foam layers have excellent sound insulation and fireproof performance, so that sound enters the cavity through the conical funnel holes, the sound is reflected and attenuated under the action of the melamine foam layers and the protrusions, and therefore the fireproof flame-retardant door has the sound insulation performance.
本发明公开了一种新型防火阻燃门，包括门框，所述门框的内壁固定连接有回形限位环，所述门框的内壁通过弹簧合页转动连接有门体，所述门体的内部开设有空腔，所述空腔的内壁固定连接有隔板，所述隔板的正面和背面均固定连接有三聚氰胺泡绵层，所述三聚氰胺泡绵层远离隔板的一侧固定连接有若干个凸起，所述门框的正面和背面均开设有若干个延伸至空腔内壁的锥形漏斗孔。该新型防火阻燃门，通过设置锥形漏斗孔、凸起和三聚氰胺泡绵层，三聚氰胺泡绵层具有优良的隔音和防火性能，使声音经锥形漏斗孔进入空腔内，在三聚氰胺泡绵层和凸起的作用下，使声音反射并衰减，从而使该防火阻燃门具备隔音的性能。
