Mullite-high silica glass composite material with closed nano-pore-diameter pores and preparation method of mullite-high silica glass composite material
The invention relates to a mullite-high silica glass composite material with closed nano-pore-diameter pores and a preparation method thereof, and belongs to the technical field of high-temperature composites.The preparation method comprises the following steps that aluminum hydroxide fine powder and fly ash fine powder are placed in a stirring pot to be stirred evenly, and mixed powder is prepared; the mixed powder is pretreated; carrying out compression molding on the pretreated mixed powder, drying, and then respectively carrying out secondary heating in a heating furnace, so as to obtain the mullite-high silica glass composite material with the closed nano-pore-diameter pores. The waste fly ash is recycled, the preparation cost is low, and the prepared product has the advantages of nano-scale closed pores, low heat conductivity coefficient, good thermal shock stability, high refractoriness, small reheating linear change, high strength and good wear resistance.
本发明涉及一种闭口纳米孔径气孔莫来石‑高硅氧玻璃复合材料及其制备方法，属于高温复合材料技术领域，包括以下步骤：将氢氧化铝细粉和粉煤灰细粉置于搅拌锅中搅拌均匀，制得混合粉体；将混合粉体进行预处理；将预处理后的混合粉体压制成型，干燥，然后在加热炉中分别进行二次加热，即得闭口纳米孔径气孔莫来石‑高硅氧玻璃复合材料。本发明将废弃物粉煤灰再利用，制备成本低，所制备制品具有纳米级别的闭气孔，导热系数低，热震稳定性好，耐火度高，重烧线变化小，强度高，耐磨性好的优点。
