High-density ceramic fiberboard and preparation method thereof
The invention provides a high-density ceramic fiberboard. The high-density ceramic fiberboard comprises the following raw materials of: less than or equal to 30wt% of aluminum oxide; no less than 7 wt% of calcium oxide and magnesium oxide; no less than 50 wt% silicon oxide; and less than or equal to 5wt% of one or more of ferric oxide, potassium oxide, sodium oxide, titanium oxide and zirconium oxide. The chemical components can be controlled, especially CaO and MgO components are introduced into soluble fibers, the resilience and elastic aftereffect of a compression-molded wet blank can be reduced, so that the density of the molded wet blank and the density and strength of a final product are improved, and product cracks caused by the elastic aftereffect are reduced. The invention furtherprovides a preparation method of the high-density ceramic fiberboard.
本发明提供了一种高密度陶瓷纤维板，包括：≤30wt％的三氧化二铝；≥7wt％的氧化钙和氧化镁；≥50wt％的氧化硅；≤5wt％的三氧化二铁、氧化钾、氧化钠、氧化钛和氧化锆中的一种或几种。本发明通过控制上述化学成分，特别是可溶纤维中CaO、MgO成分的引入可以降低压制成型后的湿坯回弹性和弹性后效，以提高湿坯成型后的密度以及最终产品的密度和强度、减少弹性后效引起的产品裂纹。本发明还提供了一种高密度陶瓷纤维板的制备方法。
