Preparation method of air filtering material based on iolite porous ceramic and zeolite
The invention relates to a preparation technology of an air filtering material, in particular to a preparation method of an air filtering material based on iolite porous ceramic and zeolite. The preparation method comprises the following steps: uniformly mixing polyvinyl alcohol and distilled water, and stirring at 85-95 DEG C to dissolve the polyvinyl alcohol to obtain a solution A; adding a zeolite molecular sieve into the solution A, and uniformly mixing to obtain a suspension B; putting cordierite porous ceramic into the suspension B at a constant descending speed of 0.5-1.5 mm/s, then pulling the cordierite porous ceramic away from the suspension B at a constant ascending and descending speed of 0.5-1.5 mm/s, drying to obtain coated cordierite porous ceramic, and repeatedly coating for more than 5 times; and roasting the dried cordierite porous ceramic to obtain the air filtering material. The preparation method is simple in process and convenient to operate, and the prepared filtering material has the characteristics of concentrated pore distribution, high porosity, low thermal expansion coefficient, high compressive strength and the like, is high in purification efficiency and high in adsorption capacity, and can be applied to air purifiers.
本发明涉及空气过滤材料制备技术，尤其涉及一种基于菫青石多孔陶瓷和沸石的空气过滤材料的制备方法。本发明将聚乙烯醇和蒸馏水混合均匀，置于温度为85～95℃下搅拌使聚乙烯醇溶解得到溶液A；将沸石分子筛加入到溶液A中混合均匀得到悬浮液B；将堇青石多孔陶瓷以0.5～1.5mm/s的下降速率匀速放入悬浮液B中，然后将堇青石多孔陶瓷以0.5～1.5mm/s的上升降速率匀速提拉离开悬浮液B，烘干得到覆膜的堇青石多孔陶瓷，重复覆膜5次以上；烘干的堇青石多孔陶瓷进行焙烧，即得空气过滤材料。本发明工艺简单，便于操作，制备的过滤材料具有孔隙分布集中、孔隙率高、热膨胀系数低、抗压强度高等特点，同时净化效率高，吸附能力强，可应用于空气净化器中。
