Porous ceramic atomizing core, preparation method thereof and electronic cigarette
The invention discloses a porous ceramic atomizing core, a preparation method thereof and an electronic cigarette. The preparation method comprises the following steps: providing raw materials including ceramic aggregate, a binder, a fluxing agent and a pore-forming agent, the pore-forming agent being selected from one or two of graphite powder and carbon powder; performing wet mixing on the ceramic aggregate, a binder, a fluxing agent and a pore forming agent to obtain a mixture; molding the mixture to obtain a green body; degreasing the green body, and removing the binder to obtain a degreased green body; then sintering the degreased green body in a vacuum or oxygen-free atmosphere, wherein the sintering temperature ranges from 1100 DEG C to 1500 DEG C, thereby forming a sintered green body; and placing the green body in an oxygen-containing atmosphere for a heating reaction, wherein the temperature of the heating reaction is 400-800 DEG C, and the pore-forming agent reacts with oxygen in the oxygen-containing atmosphere; finally removing the pore-forming agent to obtain the porous ceramic atomization core. According to the preparation method, the porous ceramic atomizing core with high strength and high porosity can be obtained.
本发明公开了一种多孔陶瓷雾化芯及其制备方法和电子烟，制备方法包括以下过程：提供原料，原料包括：陶瓷骨料、粘结剂、助熔剂和造孔剂，其中，造孔剂选自石墨粉和碳粉中的一种或两种；将陶瓷骨料、粘结剂、助熔剂和造孔剂进行湿法混合，得到混合料；将混合料进行成型，得到坯体；将坯体进行脱脂，去除粘结剂，得到脱脂后的坯体；将脱脂后的坯体置于真空或无氧气氛中进行烧结，烧结的温度为1100℃～1500℃，得到烧结后的坯体；将烧结后的坯体置于含氧气氛中进行加热反应，加热反应的温度为400℃～800℃，造孔剂与含氧气氛中的氧气反应，去除造孔剂，得到多孔陶瓷雾化芯。本发明的制备方法能够得到高强度、高孔隙率的多孔陶瓷雾化芯。
