Ceramic slurry and preparation method of porous ceramic atomizing core
The invention discloses ceramic slurry and a preparation method of a porous ceramic atomizing core, and relates to the technical field of production of electronic cigarette ceramic atomizers. The mullite whisker reinforced ceramic slurry comprises a solute accounting for 60-85% of the total mass of the ceramic slurry and a solvent accounting for 15-40% of the total mass of the ceramic slurry, the solute comprises the following components in percentage by mass: 45-60% of quartz sand, 15-28% of a sintering aid additive and 20-50% of a pore forming agent; the solvent is selected from at least three of paraffin, beewax, stearic acid, polyethylene and ethylene-vinyl acetate copolymer; the sintering aid additive is a mixture of CaCO3, AlF3, V2O5 and boron nitride. The preparation method for combining the ceramic slurry with the porous ceramic atomizing core is simple, the length-diameter ratio of the mullite whiskers in the structure is increased, the strength of a ceramic matrix is obviously improved, and therefore the thermal shock resistance is also obviously improved; the green body is high in strength, good in assembly performance, good in heat conductivity coefficient and thermal shock resistance, high in high-low temperature heat cycle frequency, uniform in large-aperture distribution and good in taste reduction degree after tobacco tar atomization.
本发明公开一种陶瓷浆料及多孔陶瓷雾化芯的制备方法，涉及电子烟陶瓷雾化器生产技术领域。一种莫来石晶须增强的陶瓷浆料，溶质占陶瓷浆料总质量的60‑85％，溶剂占陶瓷浆料总质量的15‑40％；按质量分数计，溶质中包含：石英砂45‑60％，助烧添加剂15‑28％，造孔剂为20‑50％；溶剂选自石蜡、蜂蜡、硬脂酸、聚乙烯、乙烯‑醋酸乙烯共聚物中的至少三种；所述助烧添加剂为CaCO3、AlF3、V2O5、氮化硼的混合物。本发明的陶瓷浆料结合多孔陶瓷雾化芯的制备方法简单，结构内的莫来石晶须长径比增大，陶瓷基体强度得到明显提升，因而抗热震性也得到明显提升；胚体强度高、装配性好、导热系数和抗热震性能好，高低温热循环次数高、具有均匀大孔径分布，对烟油雾化后的口感还原度好。
