Method for preparing nano anorthite porous fire-resistant heat-insulation ceramic material by foaming method
The invention relates to a nano anorthite porous refractory heat-insulation ceramic material, and belongs to the field of porous ceramics. The porous ceramic material is mainly prepared from the following raw materials in percentage by weight: 30.0 to 40.9 percent of Al2O3, 39.9 to 49.9 percent of SiO2, 0.1 to 25.1 percent of CaO, 1.0 to 10.0 percent of foaming agent, 40 to 70 percent of drinkable water and 0.5 to 8.0 percent of foam stabilizer, and the sum of the content of Al2O3, SiO2 and CaO is 100 percent. The nano anorthite porous fire-resistant thermal-insulation ceramic material is prepared by burdening, adding a foaming agent, stirring and foaming, carrying out water-retaining maintenance, drying and sintering, thereby obtaining the nano anorthite porous fire-resistant thermal-insulation ceramic material. The main phase of the porous ceramic material is an anorthite phase, and the main components of the porous ceramic material are Al2O3, CaO and SiO2. The nano anorthite porous ceramic has excellent material compressive strength, low volume density and low thermal conductivity, and a novel material can be developed for synthesis of an anorthite porous fire-resistant heat-insulation ceramic material by a foaming method and application of the anorthite porous fire-resistant heat-insulation ceramic material in an energy-saving furnace lining fire-resistant material of a high-temperature kiln.
