Method for preparing porous alumina ceramic by using hollow microspheres
The invention provides a method for preparing porous alumina ceramic by using hollow microspheres. The preparation method has the advantages of a mechanical foaming method and a gel injection method, meanwhile, the hollow resin microspheres are introduced, and the microstructure is regulated and controlled according to the particle size of the hollow microspheres. The porous alumina ceramic prepared by the method has excellent performance. 0.5-1% of hollow microspheres are additionally added, so that the porosity can be improved by 50-200%, and the pore size distribution is improved. The method has the advantages of cheap and easily available raw materials, simple process, low cost, suitability for large scale and the like, and the prepared porous ceramic can be applied to the field of large-scale industrial production.
本发明提供一种利用空心微球制备多孔氧化铝陶瓷的方法。该制备方法具备了机械发泡法和凝胶注法的优点，同时引入空心树脂微球，依托空心微球的粒径大小，对显微结构进行调控。该方法所制备的多孔氧化铝陶瓷具备优异的性能。额外添加0.5‑1%的空心微球，即可提升50%‑200%的孔隙率，并改善其孔径分布。本发明所述方法不仅具有原料价廉易得、工艺简单、成本低、适合规模化等优点，而且所制备的多孔陶瓷可大规模用工业生产领域。
