Description

一种多孔陶瓷发热体、制备方法及应用
技术领域
本发明属于电子烟技术领域，尤其涉及一种多孔陶瓷发热体、制备方法及应用。
背景技术
电子烟是一种模仿卷烟的电子产品，有着与卷烟一样的外观、烟雾、味道和感觉，它是通过雾化等手段，将尼古丁等变成蒸汽后，让用户吸食的一种产品，目前，电子烟正在以不可逆的趋势逐渐取代传统香烟。
电子烟中的核心部件为雾化芯，市面上加热燃烧的雾化芯主要分为两种，棉花雾化芯和陶瓷雾化芯，这两种雾化芯都是由多孔导油部件和发热丝组成，发热丝在使用中会一直处于高温状态。
然而，发热丝长期处于高温状态会不断氧化，导致阻值变化，进而导致发热量及均匀性皆变差，造成雾化的烟雾口感变差。此外，现有的雾化芯在制备时需要经过多次处理，包括热处理、焊接和印刷等，多次处理容易导致雾化芯的一致性出现偏差，如空隙分布、发热量、均匀性、发热区域电阻和析出面面积等。
发明内容
本发明提供一种多孔陶瓷发热体、制备方法及应用，旨在解决现有雾化芯易老化的问题。
本发明是这样实现的，一种多孔陶瓷发热体，由以下组分及重量百分数组成：骨料40-60％、烧结粘接剂5-25％、造孔剂5-20％、过渡溶剂15-30％和添加剂0-5％；
所述骨料为碳化硅、氮化硅、石墨、银、铜和锌中的至少一种；
所述烧结粘接剂为导电料与玻璃粉混匀，加入有机溶剂搅拌均匀，经轧模、模压、烧结、破碎和研磨制成，所述导电料为碳化硅、氮化硅、银、铜、锌、碳纤维、石墨和石墨烯中的至少一种，所述有机溶剂为聚乙烯醇胶水和聚乙烯醇缩丁醛胶水中的至少一种；
所述造孔剂为聚甲基丙烯酸甲酯、淀粉、活性炭和蔗糖中的至少一种；
所述过渡溶剂为聚乙烯醇胶水和油酸中的至少一种；
所述添加剂为碳纤维、炭黑、硅藻土、滑石、高岭土和堇青石中的至少一种。
更进一步地，所述骨料的粒径为15-80μm。
更进一步地，所述烧结粘接剂的粒径为1-3μm。
更进一步地，所述玻璃粉的熔融温度为450-900℃。
更进一步地，所述导电料与玻璃粉的重量比为(0.3-10):1。
更进一步地，所述造孔剂的粒径小于30μm。
更进一步地，所述过渡溶剂为聚乙烯醇胶水和油酸按照体积比10:1组成。
更进一步地，所述添加剂的粒径小于5μm。
本发明还提供多孔陶瓷发热体的制备方法，包括：按照上述重量百分数分别称取骨料、烧结粘接剂、造孔剂、过渡溶剂和添加剂混合均匀，经模压、轧模、注浆或等静压制成生坯，将生胚在500-900℃下烧结并保温0.5-3h，冷却后得到多孔陶瓷发热体。
上述制备方法制备的多孔陶瓷发热体在电子烟中的应用。
本发明提供的多孔陶瓷发热体，自身具有导电能力，无需额外添加发热丝或印刷导电线路，能够消除陶瓷与导电件之间结合性差，热传导不均和导电差异化等不良问题，比现有雾化芯的使用寿命更长。该陶瓷发热体具有多孔结构，能够与烟油充分接触，发热体内部各区域雾化量均匀，烟油雾化后口感细腻。发热方式为晶条自身发热，温度无需从发热丝中传导至晶条，能够有效节省能耗，延长使用时间。

导电料可选用碳化硅、氮化硅、银、铜、锌、碳纤维、石墨和石墨烯中的至少一种，粒径控制在20μm以内。
有机溶剂为聚乙烯醇胶水和聚乙烯醇缩丁醛胶水中的至少一种，用于将导电料和玻璃粉均匀分散在其中，并充分混合，便于加工成型成为不同的形状。
玻璃粉选用熔融温度在450-900℃，根据导电料种类的不同，导电料与玻璃粉的重量比为(0.3-10):1。
造孔剂选用聚甲基丙烯酸甲酯、淀粉、活性炭和蔗糖中的至少一种，可以在烧结过程中被烧掉，在原本的位置留下空隙，使陶瓷发热体形成多孔结构，造孔剂的粒径控制在30μm以下，粒径过大易导致漏油，不利于锁住烟油。
