Composite porous ceramic atomizing core and preparation method thereof
The invention discloses a composite porous ceramic atomizing core and a preparation method thereof, and relates to the technical field of ceramic atomizing cores. The composite porous ceramic atomizing core provided by the invention is obtained by further processing a ceramic matrix. The ceramic matrix is mainly prepared from diatomite, during preparation, the diatomite is firstly subjected to an acid leaching process, then quartz sand and kaolin which are similar to the diatomite in particle size are introduced, and diatomite/quartz sand/kaolin mixed powder is obtained through a spray drying granulation method, so that the pore structure of the diatomite and the mechanical strength of the quartz sand/kaolin are effectively combined; and performing further pressing or injection molding, degreasing and sintering to obtain the porous ceramic matrix with both strength and porosity. The ceramic atomization core is applied to the field of electronic cigarettes, the prepared ceramic atomization core contains mesopores of diatomite and macropores of quartz sand, the mesopores of the diatomite and the macropores of the quartz sand are combined, the oil guiding capacity of the atomization core is improved, the oil locking capacity of the diatomite material is reserved, and the oil leakage phenomenon is effectively prevented.
本发明公开了一种复合多孔陶瓷雾化芯及其制备方法，涉及陶瓷雾化芯技术领域。本发明提供的复合多孔陶瓷雾化芯由陶瓷基体经进一步加工得到。该陶瓷基体以硅藻土为主，制备时先对硅藻土使用酸浸工艺，再引入与硅藻土粒径大小相似的石英砂及高岭土，通过喷雾干燥制粒的方法获得硅藻土/石英砂/高岭土混合粉末，有效结合了硅藻土的孔洞结构以及石英砂/高岭土的机械强度，再经过进一步压制或者注塑成型、脱脂、烧结，得到强度、孔隙率兼得的多孔陶瓷基体。其应用在电子烟领域，制得的陶瓷雾化芯含有硅藻土的介孔与石英砂的大孔，两种孔洞相结合，既提升了雾化芯的导油能力，又保留了硅藻土材料的锁油能力，有效预防漏油现象。
