Humidity-sensitive porous ceramic, atomizing core and preparation method thereof
The invention relates to a humidity-sensitive porous ceramic, an atomizing core and a preparation method of the humidity-sensitive porous ceramic, wherein the humidity-sensitive porous ceramic is prepared from a base material including 1-20 parts of a component A, 1-10 parts of a component B, 1-20 parts of a component C, 1-30 parts of a pore forming agent and 1-10 parts of a sintering aid; wherein the component A is SnO2, ZnO and TiO2, the component B is LiZnVO4, ZnCrVO4, V2O5 and Fe2O3, and the component C is one or more of Li2O, Na2O, K2O, MgO and CaO; the atomizing core comprises a liquid guide body and a heating element; the liquid guide body is made of humidity-sensitive porous ceramic. The preparation method comprises the following steps: (1) weighing the component A, the component B, the component C, the pore-forming agent and the sintering aid, and mixing and ball-milling all the componetns in a ball-milling device; (2) baking and drying the mixture to obtain mixed powder; (3) heating paraffin to melt, and adding the mixed powder while stirring to obtain paraffin slurry; (4) injecting the paraffin slurry into a mold, and cooling the slurry to obtain a wax mold; (5) putting into a furnace to remove wax to obtain a wax-removed sample; and (6) sintering the sample in a protective atmosphere to obtain the humidity-sensitive porous ceramic.
本发明涉及湿敏多孔陶瓷、雾化芯及其制备方法，湿敏多孔陶瓷由基体材料包括A组分1‑20份、B组分1‑10份、C组分1‑20份、造孔剂1‑30份和烧结助剂1‑10份制成，A组分为SnO2、ZnO、TiO2，B组分为LiZnVO4、ZnCrVO4，V2O5、Fe2O3，C组分为Li2O、Na2O，K2O，MgO，CaO中的一种或多种；雾化芯包括导液体和发热元件，导液体由湿敏多孔陶瓷制成；制备方法包括：⑴称取A组分、B组分、C组分、造孔剂和烧结助剂，置于球磨装置中混合球磨；⑵烘烤干燥得到混合粉料；⑶将石蜡加热至融化边搅拌边加入混合粉料得到石蜡浆料；⑷将石蜡浆料注入模具中，冷却得到蜡模；⑸放入炉中除蜡得到除蜡样；⑹在保护气氛中进行烧结得到湿敏多孔陶瓷。
