Preparation method of high-strength electronic cigarette ceramic atomization core
The invention relates to the technical field of electronic cigarettes, and discloses a preparation method of a high-strength electronic cigarette ceramic atomization core, which comprises the following steps: mixing SiO2, Al2O3, alkali metal oxide and alkaline earth metal oxide powder and pore-forming powder with paraffin and oleic acid, heating, stirring and mixing by a stirrer, putting the stirred mixed slurry into an injection molding machine, and carrying out injection molding to obtain the high-strength electronic cigarette ceramic atomization core. A lower injection mold of an injection molding machine is used for injection molding to obtain a ceramic green body, the ceramic green body is degreased and sintered to obtain a ceramic base body, heating slurry is silk-printed on the ceramic base body, and the required ceramic atomization core is obtained after vacuum sintering. According to the preparation method of the high-strength electronic cigarette ceramic atomizing core, the molar ratio of aluminum oxide to alkali metal oxide is moderate, the ceramic matrix is prevented from shrinking violently during sintering, the prepared atomizing core is high in porosity, and the problems that the sintering activity of the material is too large, the temperature of powder is too high during sintering and the liquid phase is insufficient during sintering are solved; the strength of the ceramic matrix is better, and the service life of the electronic cigarette is longer.
本发明涉及电子烟技术领域，且公开了一种高强度电子烟陶瓷雾化芯制备方法，将SiO2，Al2O3，碱金属氧化物和碱土金属氧化物粉体以及造孔粉与石蜡和油酸混合，通过搅拌机进行加热搅拌混合，将搅拌的混合浆料放入压注机中，通过压注机下注模具进行压注得到陶瓷坯体，将陶瓷坯体进行脱脂烧结，得到陶瓷基体，在陶瓷基体上丝印发热浆料，经过真空烧结后得到所需陶瓷雾化芯。该高强度电子烟陶瓷雾化芯制备方法，所使用的氧化铝和碱金属氧化物和的摩尔比适中，防止陶瓷基体在烧结时收缩剧烈，所制备出的雾化芯孔隙率高，防止材料的烧结活性太大，粉料在烧结时温度过高，且由于烧结时液相不足的问题，使陶瓷基体强度更好，使电子烟的使用寿命更长。
