Porous ceramic heating body and preparation method thereof
The invention relates to the technical field of electronic cigarettes, in particular to a porous ceramic heating body and a preparation method thereof. The porous ceramic heating body comprises a porous ceramic matrix and a metal heating element. The porous ceramic matrix comprises the following raw materials in parts by weight: 1-20 parts of emery, 30-50 parts of quartz sand, 10-50 parts of diatomite, 1-5 parts of magnesium carbonate, 1-5 parts of calcium carbonate and 5-20 parts of a pore forming agent. The porous ceramic heating body is novel in structure, high in product porosity and highin strength; the metal heating element is not oxidized; the diatomite forms gaps under the action of the pore forming agent, so the porosity of the produced porous ceramic heating body is guaranteed;magnesium carbonate and calcium carbonate can decompose a part of carbon dioxide gas under a high-temperature condition, so porosity is improved; and magnesium oxide and calcium oxide generated afterhigh-temperature decomposition form aluminosilicate together with silicon dioxide and aluminum oxide, so the inter-binding property of material particles is improved, and the structural stability andstrength of the porous ceramic matrix are improved.
本发明涉及电子烟技术领域，具体涉及一种多孔陶瓷加热体及其制备方法。该多孔陶瓷加热体包括多孔陶瓷基体和金属发热件，多孔陶瓷基体包括如下重量份的原料：刚玉砂1‑20份、石英砂30‑50份、硅藻土10‑50份、碳酸镁1‑5份、碳酸钙1‑5份、造孔剂5‑20份。本发明的多孔陶瓷加热体结构新颖，产品孔隙率高，强度高，金属发热件不被氧化，其中，硅藻土在造孔剂的作用下形成空隙，保证产品的孔隙率；碳酸镁和碳酸钙在高温条件下能分解出部分二氧化碳气体，提高孔隙率，且高温分解后产生的氧化镁、氧化钙与二氧化硅和氧化铝形成铝硅酸盐，提高物料颗粒之间的结合性，提高多孔陶瓷基体的结构稳定性和强度。
