Aerogel atomizing core, preparation method thereof and electronic cigarette
The invention relates to the technical field of electronic cigarettes, in particular to an aerogel atomizing core, a preparation method thereof and an electronic cigarette. The preparation method of the aerogel atomizing core comprises the following steps: carrying out molding treatment on slurry containing a silicon source, a carbon source and a thickening agent to prepare a green body; carrying out sintering treatment on the green body to prepare a silicon nitride fiber aerogel matrix; carbon coatings are formed on the surface and inside the silicon nitride fiber aerogel matrix through a chemical vapor impregnation method, and inorganic fiber aerogel is prepared; and forming a heating layer on the inorganic fiber aerogel to prepare the aerogel atomizing core. According to the preparation method provided by the invention, the use of a large amount of organic solvent can be avoided, the environmental pollution is extremely low, and the prepared aerogel atomizing core has the advantages of high mechanical strength, high porosity, large aperture and fast oil guide, and shows excellent oil guide and atomization performance, so that the use effect of the electronic cigarette is effectively improved.
本申请涉及电子烟的技术领域，特别是涉及一种气凝胶雾化芯及其制备方法和电子烟。所述气凝胶雾化芯的制备方法，包括以下步骤：对含有硅源、碳源和增稠剂的浆料进行成型处理，制备生坯；对所述生坯进行烧结处理，制备氮化硅纤维气凝胶基体；通过化学气相浸渍法在所述氮化硅纤维气凝胶基体表面及内部形成碳涂层，制备无机纤维气凝胶；在所述无机纤维气凝胶上形成加热层，制备气凝胶雾化芯。本申请提供的制备方法不仅可以避免使用大量有机溶剂，环境污染性极低，而且制得的气凝胶雾化芯具有力学强度高、孔隙率高、孔径大、导油快的优势，表现出优异的导油和雾化性能，从而有效地提升电子烟的使用效果。
