Flame-retardant building external wall insulation board
The invention provides a flame-retardant building external wall insulation board, and belongs to the technical field of building insulation boards, the flame-retardant building external wall insulation board comprises a main board body, the side wall of the main board body is fixedly connected with an outer layer board, and an inner cavity of the main board body is slidably connected with an inner layer board; through the arrangement of a first feeler lever, a flame-retardant ball, a closing plate, a second spring, a communicating groove and a spraying opening, flame-retardant powder filled in the flame-retardant ball is sprayed outwards from the spraying opening and the communicating groove through impact force generated by puncture explosion, so that the surface of a comburent is covered, flame combustion is effectively hindered, and the flame-retardant effect is improved. Therefore, the fire spreading inhibiting effect of the device is improved; and during explosion, by means of the arrangement of a second feeler lever, a water storage bag, a puncture rod and a sealing plug, water flow carries the flame-retardant powder which is not sprayed out to flow downwards along a water guide groove, so that a layer of pasty fire suppression net is formed on the surface of the outer layer plate, fire spreading is further suppressed, and the flame-retardant effect of the device is improved.
本发明提供了一种阻燃型建筑外墙保温板，属于建筑保温板技术领域，包括主板体，主板体侧壁固定连接有外层板，主板体内腔滑动连接有内层板；该发明通过第一触杆、阻燃球、封闭板、第二弹簧、连通槽以及喷撒口的设置，将会使得阻燃球内填充的阻燃粉末，通过刺破爆炸产生的冲击力，从喷撒口以及连通槽向外喷撒，以此将燃烧物表面进行覆盖，有效阻碍火焰的燃烧，从而提高了该装置的抑制火势蔓延的效果；并且在爆炸的同时，利用第二触杆、储水袋、穿刺杆以及密封塞的设置，将会使得水流带着未喷撒出去的阻燃粉末顺着引水槽向下流动，以此在外层板表面形成一层水糊状的抑火网，进一步抑制了火势的蔓延，从而提高了该装置的阻燃效果。
