Humidity-sensitive porous ceramic, atomization core and preparation method of ceramic
The invention discloses humidity-sensitive porous ceramic, an atomization core and a preparation method of the humidity-sensitive porous ceramic. The humidity-sensitive porous ceramic is prepared by mixing a humidity-sensitive material and a base material, the humidity-sensitive material comprises 1-30 parts of MgO, 1-60 parts of Cr2O3, 1-30 parts of TiO2 and 1-15 parts of NH4VO3, and the base material comprises 1-50 parts of a ceramic powder material, 1-50 parts of a pore forming agent and 1-10 parts of a sintering aid. The atomization core comprises a liquid guide body and a heating element, and the liquid guide body is made of the humidity-sensitive porous ceramic. The preparation method comprises the following steps: (1) weighing MgO, Cr2O3, TiO2, NH4VO3, a ceramic powder material, a pore-forming agent and a sintering aid, and conducting mixing and ball-milling in a ball-milling device; (2) conducting baking and drying 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 conducting cooling and demolding to obtain a wax mold; (5) conducting dewaxing to obtain a dewaxed sample; and (6) conducting sintering in a protective atmosphere to obtain the humidity-sensitive porous ceramic.
本发明的湿敏多孔陶瓷、雾化芯及其制备方法，湿敏多孔陶瓷由湿敏材料和基体材料混合制成，湿敏材料包括1‑30份MgO，1‑60份Cr2O3，1‑30份TiO2，1‑15份NH4VO3，基体材料包括1‑50份陶瓷粉体材料，1‑50份造孔剂，1‑10份烧结助剂；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；制备方法包括步骤：⑴称取MgO、Cr2O3、TiO2、NH4VO3、陶瓷粉体材料、造孔剂、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，冷却脱模后得到蜡模；⑸进行除蜡得到除蜡样；⑹在保护气氛中进行烧结得到湿敏多孔陶瓷。
