The invention relates to the field of ceramic materials, in particular to a preparation method of a microporous ceramic atomizing core, ceramic powder, a sintering aid, a bonding component and a pore-forming agent are mixed, granulated and subjected to injection molding to obtain a green body, and the green body is heated, degummed and sintered, the particle size of the pore-forming agent is 1-50 microns, mesophase pitch is used as a core body of the pore-forming agent, and the pore-forming agent is a mixture of mesophase pitch and pore-forming agent. The silica sol is used as an inner shell, the acrylate polymer is used as an outer shell, and the prepared microporous ceramic atomization core has high porosity and mechanical property, high heat conductivity and high oil absorption rate, is used for manufacturing electronic cigarettes and can provide better smoking taste.
本发明涉及陶瓷材料领域，具体为一种微孔陶瓷雾化芯的制备方法，将陶瓷粉体、烧结助剂、粘结组分和造孔剂混炼后、造粒、注射成型，得到生坯，将所述生坯升温排胶并烧结即可，所述造孔剂的粒径为1‑50μm，所述造孔剂以中间相沥青为核体，以硅溶胶为内壳，以丙烯酸酯类聚合物为外壳，本发明所制备的微孔陶瓷雾化芯具有较高的气孔率和力学性能，且热导率高，吸油速率快，用于制作电子烟，可以提供更好的抽吸口感。
