Preparation method of ultra-low-density rigid ceramic heat insulation tile
The invention discloses a preparation method of an ultra-low-density rigid ceramic heat insulation tile, and belongs to the technical field of preparation of high-performance thermal protection materials.The method comprises the steps that ceramic fibers are added into water to be evenly mixed, and ceramic fiber slurry is obtained; uniformly mixing the sintering aid powder with the polymer solution to obtain a sintering aid mixture; stirring the ceramic fiber slurry, then adding the sintering aid mixture inwards in an intermittent spraying manner, and continuously stirring after the addition is completed, so as to obtain heat-insulating tile slurry; transferring the heat-insulating tile slurry into a filtering tool, standing and precipitating, taking away clear liquid above a precipitate deposit from the upper part until the precipitate deposit is exposed out of the water surface, and then filtering redundant water from a filter screen below the filtering tool to obtain a heat-insulating tile wet blank; drying the wet heat insulation tile blank to obtain a dry heat insulation tile blank; and putting the dry heat insulation tile blank into a closed ceramic box, and then transferring the dry heat insulation tile blank into a muffle furnace for sintering to obtain the ultra-low-density rigid ceramic heat insulation tile.
本发明公开了一种超低密度刚性陶瓷隔热瓦的制备方法，属于高性能热防护材料制备技术领域，本方法将陶瓷纤维加入到水中混合均匀，得到陶瓷纤维浆料；将烧结助剂粉体与高分子溶液混合均匀，得到烧结助剂混合物；将陶瓷纤维浆料进行搅拌，然后向内以间歇式喷射的方式加入烧结助剂混合物，加入完成后继续搅拌，得到隔热瓦浆料；将隔热瓦浆料转移至过滤工装中，静置沉淀后，将沉淀堆积物上方的清液从上方取走，直至沉淀堆积物露出水面，然后从过滤工装下方滤网将多余的水滤除，得到隔热瓦湿坯；将隔热瓦湿坯进行干燥，得到隔热瓦干坯；将隔热瓦干坏装入至密闭的陶瓷匣子内，然后转移至马弗炉中进行烧结，得到超低密度刚性陶瓷隔然瓦。
