Preparation method of porous ceramic material and porous material obtained by method
The invention relates to a preparation method of a porous ceramic material for an electronic cigarette, the porous ceramic material prepared by the method, and application of the porous ceramic material in an electronic cigarette atomizer. According to the preparation method disclosed by the invention, natural medical stone is used as a main aggregate of a porous ceramic, and can be fired and formed under normal pressure under conventional atmospheric conditions, wherein the sintering condition is mild, a two-step firing process of preserving heat at 450-550 DEG C for 0.5-3 hours and then raising the temperature to 800-950 DEG C for preserving heat and sintering for 0.3-2 hours can be adopted, low-melting-point glass powder and other assistants are not introduced, the medical stone particles have a large number of micropore and mesopore structures, the porosity of 90% or above can be obtained by combining the medical stone particles with a pore forming agent, and the medical stone particles have the bending strength of 20 MPa or above. The obtained porous ceramic used as an electronic cigarette atomization core material can achieve zero release of toxic elements.
本发明涉及一种电子烟用多孔陶瓷材料的制备方法，采用该方法制备得到的多孔陶瓷材料及其在电子烟雾化器中的应用。本发明的制备方法将天然麦饭石作为多孔陶瓷的主要骨料，可以在常规大气条件下于常压下烧制成型，烧结的条件温和，可以采用450～550℃保温0.5～3小时、再升温至800～950℃保温烧结0.3～2小时的两步法烧制流程，无需引入低熔点的玻璃粉等助剂。麦饭石的颗粒本身即具有大量的微孔、介孔结构，再结合造孔剂，可以获得90％以上的孔隙率，同时具备20MPa以上的抗弯强度。得到的多孔陶瓷作为电子烟雾化芯材料使用，有毒元素零释放。
