Description

外墙真空保温板
技术领域
本实用新型涉及一种建筑材料，尤其涉及一种外墙真空保温板。
背景技术
现有的外墙保温一般是用EPS、XPS或PU，由于材料本身导热系数较大[EPS是0.041w/(m·K)，XPS是0.029w/(m·K)，PU是0.022w/(m·K)]，为了满足建筑节能的要求，在达到相同的保温效果时保温层厚度较大；另外，EPS、XPS、PU的燃烧性能不能达到公安部要求的A级标准；同时PU施工受风力的影响较大；而浆料类保温材料因施工质量控制难度极大，已被各地建设主管部门明令禁止使用了。
发明内容
本实用新型的目的是提供一种绿色环保、A级防火、保温效果突出、隔声的外墙保温新型高科技板材。
本实用新型的目的是这样实现的：外墙真空保温板，主要由有机芯材、无纺布、铝箔真空隔热袋组成，将有机保温材料(开孔聚氨酯泡沫，开孔聚苯乙烯泡沫等)经特殊工艺压制成有机芯材，外层包上无纺布，形成有机保温芯材，然后将成型的有机保温芯材装入高阻燃的铝箔真空隔热袋内，利用真空机组抽取袋内空气进行封装而成。
同现有技术相比，本实用新型由于①采用了低导热的保温材料，将物体之间的热传导降到最低；②通过真空机组抽得的高真空，将气流的流动传热降到最低；③采用的纯铝箔结构，对热辐射进行了有效的反射。在原有保温材料的基础上复合以上诸项措施，最终使得该保温板的导热系数大大降低在≤0.007W/(m·K)之下。所以较薄的保温层即可达到较厚的EPS、XPS、PU的保温效果，我国大部分地区只需要使用13mm厚的板材，即可达到建筑节能65％的要求；另外，采用高阻燃的铝箔袋，利用抽真空技术将可燃的有机保温材料进行封装，使外墙保温板的燃烧性能达到了A2级要求，这样就消除了火灾隐患。
附图说明
图1为本实用新型的结构示意图。
参考图1所示，图中编号为：1、有机芯材，2、无纺布，3、铝箔真空隔热袋。
具体实施方式
将有机保温材料(开孔聚氨酯泡沫，开孔聚苯乙烯泡沫等)经特殊工艺压制成有机芯材(1)，外层包上无纺布(2)，形成有机保温芯材，然后将成型的有机保温芯材装入高阻燃的铝箔真空隔热袋(3)内，利用真空机组抽取袋内空气进行封装而成。
安装时，用专用的粘结砂浆采用点框法或条粘法粘贴在基层墙体上。
