本发明涉及一种莫来石-钙长石-刚玉复相微孔隔热材料及其制备方法，属于无机隔热材料技术领域。
背景技术
近年来，随着能源的日趋枯竭，节能、环保、减少能源消耗已受到到社会发展极大的重视。为进一步减少排放，高温隔热材料在高温工业中得到了大量的使用。传统的隔热材料多数使用温度较低，只能在隔热层和保温层使用，已经很难满足高温工业的应用要求。开发强度高、导热系数低、高温性能优良的隔热材料是当前最为迫切的任务。
高温隔热材料的生产工艺方法通常为加入燃烬物法和发泡法。加入燃尽物法是在原料中添加适量的有机物，如聚轻球、锯木屑、淀粉等；发泡法是加入松香、双氧水发泡，这两种方法存在着生产过程有污染或者生产成本高，所得到的材料气孔大小不均匀等问题。
目前，钙长石轻质隔热材料在制备方法上出现了一些新的工艺，如发明专利“钙长石轻质隔热耐火材料及其制备方法”(CN 102491766 A)和发明专利“钙长石轻质耐火砖及其制备方法”(CN 102942376 A)均采用浇注成型的方法制备，以水为成孔剂，未添加烧失物和发泡剂，但该方法工艺仍复杂，干燥时间长，煅烧后需要切割处理，增加了生产成本，制备的钙长石轻质耐火隔热材料以钙长石单相为主，使用温度相对较低。
发明内容
本发明的目的在于提供一种莫来石-钙长石-刚玉复相微孔隔热材料，其原料来源广泛，成本低，使用温度高，隔热效果好；本发明同时提供了一种简单易行、节能环保的制备方法。

制备所述的莫来石-钙长石-刚玉复相微孔隔热材料时，向上述所有原料中加入占比3～6wt％的结合剂。
