Porous ceramic, preparation method thereof, atomizing core and electronic atomizing device
The invention discloses porous ceramic and a preparation method thereof, an atomization core and an electronic atomization device, the porous ceramic is prepared from ceramic raw materials, the ceramic raw materials comprise inorganic powder and organic components, and the inorganic powder comprises, by weight, 35-80 parts of ceramic aggregate, 5-30 parts of a binder, 5-20 parts of a pore forming agent, 3-15 parts of a sintering aid and 3-12 parts of expandable graphite. By adding the expansible graphite, the volume of the expansible graphite can be rapidly expanded in the high-temperature sintering process, shrinkage of the ceramic matrix can be resisted, integrated sintering preparation of the porous ceramic body and the oil guide pipe is promoted, and a sintered finished product has reliable structural stability and high production efficiency; in addition, the porous ceramic atomizing core has certain heat conduction performance, and the problems that a high-viscosity aerosol generating matrix cannot be fully preheated, the oil conduction rate of the high-viscosity aerosol generating matrix in the ceramic atomizing core is low, oil supply is insufficient during suction and the like can be solved.
一种多孔陶瓷及其制备方法、雾化芯、电子雾化装置，多孔陶瓷由陶瓷原料制备而成，陶瓷原料包括无机粉料和有机组分，无机粉料以重量计份，包括陶瓷骨料35‑80份、粘结剂5‑30份、造孔剂5‑20份、烧结助剂3‑15份及可膨胀石墨3‑12份。本发明通过添加可膨胀石墨，在高温烧结过程中其体积可迅速得到膨胀，可以抵抗陶瓷基体收缩，促进多孔陶瓷本体、导油管一体烧结制备，所烧结成型的成品具有可靠的结构稳定性，生产效率高，且可解决现有陶瓷雾化芯装配麻烦、装配不紧凑容易漏油的问题，另外本发明多孔陶瓷雾化芯具有一定的导热性能，可解决高粘度的气溶胶生成基质不能充分预热，其在陶瓷雾化芯中导油速率偏低，抽吸时出现供油不足等问题。
