Preparation method of alumina-based porous ceramic material
The invention relates to a preparation method of a porous ceramic material, in particular to a preparation method of an alumina-based porous ceramic material, which comprises the following steps: preparing the following raw materials in percentage by weight: 35-50% of aluminum oxide powder, 2-6% of binder and 0.5-2% of sintering aid, wherein the content of the pore-forming agent is 42-65%, the sum of the mass percentages of the components is 100%, the binder is phenolic resin, the sintering aid is CaO and ZrO2, and the pore-forming agent is ultrafine polymethyl methacrylate powder; and carrying out ball milling and mixing, pressing the mixture into a blank, and sintering and cooling the blank to obtain the alumina-based porous ceramic material. By adopting a proper preparation process, the alumina-based porous ceramic material is low in sintering temperature, simple in process and low in cost, and also has high porosity and good toughness.
本发明涉及一种多孔陶瓷材料的制备方法，尤其是涉及一种氧化铝基多孔陶瓷材料的制备方法，按重量百分比计，包括如下步骤：准备原料：按质量百分比计，所述原料中，氧化铝粉体的含量为35‑50％，粘结剂的含量为2‑6％，助烧剂的含量为0.5‑2％，造孔剂的含量为42‑65％，上述各组分的质量百分比之和为100％，其中，粘结剂为酚醛树脂，助烧剂为CaO及ZrO2，造孔剂为超细聚甲基丙烯酸甲酯粉；球磨混料，压制成毛坯，烧结后冷却，得到氧化铝基多孔陶瓷材料。采用合适的制备工艺，得到的氧化铝基多孔陶瓷材料其烧结温度低，工艺简单、成本低，还具有的高孔隙率，强韧性好。
