Description
技术领域
本发明属于安全工程技术领域，具体涉及一种气凝胶防火门芯板。
背景技术
防火门是消防设施中的重要组成部分，与一般防盗门的区别主要在于其门板内填料是防火材料，具有较好的耐火性和隔热性，在发生火灾条件下，可起到阻止火势蔓延、隔离未燃可燃物的作用，为人员疏散提供宝贵的时间。
防火门芯板是防火门的核心组成部件，目前市场上的防火门芯板主要填充材料为蛭石、硅酸铝棉、岩棉、无机发泡和珍珠岩防火板。气凝胶材料具有三维纳米网络结构，是一种新型的轻质纳米多孔非晶固态材料，并且具有高孔隙率、低密度、低热导率、不燃等特点，是制作防火门芯板的理想材料。将气凝胶与其他材料复合，弥补其易碎的缺点，可极大提高防火门隔热性能，减轻防火门重量。
发明内容
本发明目的是提供一种气凝胶防火门芯板，以弥补现有技术的不足，来满足生产的需要。
本发明一种气凝胶防火门芯板，包括气凝胶层及复合防火层。
作为本发明的一种优选方案，所述的气凝胶层为二氧化硅气凝胶粉末与玻璃纤维、聚四氟乙烯等组成的复合材料。
作为本发明的一种优选方案，气凝胶粉末中位粒径大于25微米。
作为本发明的一种优选方案，所述的复合防火层表面为气凝胶涂层。
本发明的有益效果为，所述一种气凝胶防火门芯板以气凝胶复合材料为基板，在正反两面设置复合防火层，且复合防火层表面为气凝胶涂层，大大提高了防火隔热性能，采用气凝胶复合材料作为芯材，不仅提高了防火门整体防火性能和隔声性能，且降低了防火门重量。本发明结构合理，所使用的材料易得，工作性能稳定、操作简单、可实现重复性地操作，适应大规模工业生产的需要。
附图说明
图1为本发明一种气凝胶防火门芯板的结构示意图。
具体实施方式
