Porous ceramic for electronic cigarette atomization core with low thermal conductivity and high porosity and preparation method of porous ceramic
The invention discloses porous ceramic for an electronic cigarette atomization core with low thermal conductivity and high porosity and a preparation method of the porous ceramic, and particularly relates to the field of ceramic materials. Raw materials used in the invention comprise, by mass, 1%-15% of mullite, 40%-60% of diatomite, 5%-25% of alumina hollow spheres, 1%-5% of foamy carbon powder, 10%-15% of a pore-forming agent, 1%-8% of an inorganic binder and 0.1%-0.5% of a retarder. The diatomite, mullite and dense foam carbon in the raw materials are of a porous structure, the aluminum oxide hollow spheres are of a hollow structure, the pore-forming agent can be used for forming pores in the porous ceramic, meanwhile, mullite can also play a role of aggregate, and through reasonable matching according to the proportion, the prepared porous ceramic atomizing core has relatively low thermal conductivity and relatively high apparent porosity.
本发明公开了低导热率高孔隙率电子烟雾化芯用多孔陶瓷及其制备方法，具体涉及陶瓷材料领域，所使用原料按照质量百分比计算包括1％‑15％莫来石、40％‑60％的硅藻土、5％‑25％的氧化铝空心球、1‑5％的泡沫碳粉、10％‑15％的造孔剂、1‑8％的无机粘结剂和0.1‑0.5％缓凝剂。本发明原料中的硅藻土、莫来石、泡密碳为多孔结构，氧化铝空心球为中空结构，造孔剂又能够给多孔陶瓷制造孔洞，同时莫来石还可以起到骨料作用，通过按照上述配比合理搭配，使得制备得到的多孔陶瓷雾化芯具有较低的导热率和较高的显气孔率。
