The invention discloses a glass magnesium board with fire resistance and heat preservation functions and a preparation method of the glass magnesium board, and the glass magnesium board comprises thefollowing raw materials in parts by weight: 20-30 parts of light calcined magnesia, 20-30 parts of magnesium chloride hexahydrate, 20-30 parts of kaolin, 10-20 parts of talc, 0.1-0.5 part of a water-resistant modifier and 1.2-2 parts of an excitant. In the glass magnesium board preparation process, a complex magnesium-based system MgO-Al2O3-SiO2 exists, sufficient mechanical support is provided for the formation of new crystalline phases; wherein the kaolin and the talc are finally added, and the siliceous talc has a decisive influence on the fire resistance and the heat preservation performance of the glass magnesium board; the defects of the original glass magnesium board are overcome, the internal crystal structure is more compact, and the prepared board has the advantages of excellentbreaking strength and impact strength, lower heat conductivity coefficient, heat insulation effect, long fire-resistant time and the like.
本发明公开了一种具有耐火保温功能的玻镁板及其制备方法，所述耐火保温功能的玻镁板包括如下重量份数原料：20‑30份轻烧氧化镁、20‑30份六水氯化镁、20‑30份高岭土、10‑20份滑石、0.1‑0.5份抗水改性剂、1.2‑2份激发剂，玻镁板在制备过程中，存在复杂的镁基体系MgO‑Al2O3‑SiO2，这些新的晶相的形成提供了足够的力学支撑；其中高岭土和滑石最后加入，含硅质的滑石对于玻镁板的耐火保温性能具有决定性的影响；改善了原有玻镁板的一些缺点，使内部晶体结构更加致密，使得所制备的板材具有抗折强度、抗冲击强度优良，导热系数较低，具有隔热保温的效果，且耐火时间长等优点。
