Abstract

一种气凝胶超低导热高阻燃型保温板，采用纳米二氧化硅气凝胶为主体材料，添加其他填充材料复合而成。它具有优越的隔热性能。常温室温时平均导热系数为0.012‑0.019W/M、K，在高温环境中使用时隔热性能更加突出。不同系列的本材料可分别耐受最高450℃‑1000℃的高温，低温使用范围接近绝对零度。独特的耐火焰烧穿型性能。这是板材类常规高温隔热材料所不具有的。本材料可以钻孔，切割，铆接而不对本体造成巨大的损伤，用裁纸刀即可以加工高温下不释放任何气体或有机物，对于环境的保护也有着一定的保障性，所以这也是保温材料批发商一致推荐的建筑工程材料。

Description

一种气凝胶超低导热高阻燃型保温板
一、技术领域
本发明涉及一种气凝胶超低导热高阻燃型保温板，具有良好保温隔热、阻燃效果的建筑类外墙保温材料，它是有关建筑外墙保温工程用板材。
二、背景技术
一种气凝胶超低导热高阻燃型保温板具有良好保温隔热、阻燃效果。目前保温材料的使用不仅仅影响着建筑工程的质量，更关系到整个房屋建筑的后期使用。好的保温性能能够保证建筑室内气温的恒定及舒适，所以这就要求建筑工程在进行保温材料批发选择的时候，正确的选择合适的保温材料来进行一定的外墙保温处理，这样才能保证施工后的整体保温性能。保温材料的种类繁多，那么我们该如何来选择保温材料呢？其实对于保温材料的选择来说，首先我们要根据建筑墙体和建筑后期的使用来确定保温材料的选择，然后再根据我们所选保温材料的品质来细分保温材料的实际应用。下面就来介绍一种新型的保温材料，一种气凝胶超低导热高阻燃型保温板。它的应用得到了广泛的使用，正在逐渐被广大的保温材料批发商所认可。一种气凝胶超低导热高阻燃型保温板特点介绍1、优越的隔热性能。常温室温时平均导热系数为0.012-0.019W/M、K，在高温环境中使用时隔热性能更加突出。不同系列的本材料可分别耐受最高450℃-1000℃的高温，低温使用范围接近绝对零度。2、独特的耐火焰烧穿型性能。气凝胶保温材料可长时间承受火焰直接灼烧，在远超使用上限温度的火焰中，气凝胶保温材料会出现隔热性能退化的趋势并伴有烧结现象，但不会出现一半纤维类隔热材料熔断穿孔或者多孔矿物板类隔热材料断裂破碎的情况。3、很好的化学稳定性。气凝胶保温材料可长期耐受除氢氟酸外的大部分酸碱环境，不分解不变质，可长期耐受各种热辐射及电磁辐射，性能不退化，在常规使用环境下具有极长的寿命，这点同时也省了日常对其的维护与保养。4、良好的力学特性。拉伸机械强度>2Mpa(刚性产品)，>0.12Mpa(柔性产品)。并具有一定程度上的弹性，这是板材类常规高温隔热材料所不具有的。本材料可以钻孔，切割，铆接而不对本体造成巨大的损伤，用裁纸刀即可以加工5、在高温下不释放任何气体或有机物，对于环境的保护也有着一定的保障性，所以这也是保温材料批发商一致推荐的建筑工程材料。
