Processing technology of special plate for integrated fireproof smoke exhaust air duct
The invention discloses a processing technology of a special plate for an integrated fireproof smoke exhaust air duct. The processing technology comprises the following steps: A, respectively manufacturing a heat insulation core layer, a fireproof layer and a decorative surface layer; and B, after the surface of the fireproof layer is coated with environment-friendly acrylic acid glue, pasting the face with the glue to the surface of the heat insulation core layer, and carrying out compounding through a hot press. The fireproof layer, the heat insulation core layer and the decorative surface layer are compounded through a hot press, the decorative surface layer is made of PE or aluminum foil, the heat insulation core layer is made of high-temperature-resistant vertical-wire rock wool, the fireproof layer is made of a high-strength gelling inorganic material, meanwhile, the high-strength gelling inorganic material is composed of magnesium sulfate, calcium silicate, magnesium oxide, plant fibers, aluminum sulfate fibers, a modifier, bentonite, a foaming agent and water, so that the special plate for the integrated fireproof smoke exhaust air duct can resist the high temperature of 1000 DEG C, the combustion performance reaches the A1 level, the strength is high, sound insulation and heat insulation are achieved, cracking and deformation are avoided in the machining and using process, and the service life is 20 years or longer.
本发明公开了集成防火排烟风管专用板加工工艺，其加工工艺包括以下步骤：A、分别制作隔热芯层、防火层和装饰面层；B、将防火层的表面涂覆环保型丙烯酸胶水后将有胶水的一面粘贴在隔热芯层的表面，并通过热压机复合。本发明将防火层与隔热芯层和装饰面层之间通过热压机复合，且装饰面层的材料为PE或铝箔，隔热芯层的材料为耐高温竖丝岩棉，防火层的材料为高强度胶凝无机材料，同时，高强度胶凝无机材料由硫酸镁、硅酸钙、氧化镁、植物纤维、硫酸铝纤维、改性剂、膨润土、发泡剂和水组成，使本集成防火排烟风管专用板能耐受1000℃高温，燃烧性能达到A1级，强度高且隔音、隔热，加工、使用过程中不开裂，不变形，使用寿命20年以上。
