Description

一种低温卷烟用发热体材料及其制备方法和应用
技术领域
本发明属于烟草制品技术领域，尤其涉及一种低温卷烟用发热体材料及其制备方法和应用。
背景技术
目前市场上应用于烟草加热不燃烧的发热器件主要包括电阻加热及电磁感应加热，其中以电阻加热的应用较为广泛。其中电阻加热元件主要为MCH陶瓷。虽然能够有效对低温卷烟中雾化基质进行加热雾化，但仍存在较多问题。如制备工艺复杂、成本较高，产品质量波动较大等问题，另一方面，由于发热金属被氧化铝陶瓷包裹，因此不能对烟草薄片直接加热，很大程度降低了加热效率，且印刷线路也导致了加热区间的不均匀性。因此急需开发一种低成本、工艺简单、可靠性高及可控性强的新型发热材料。
发明内容
有鉴于此，本发明的目的在于提供一种低温卷烟用发热体材料及其制备方法和应用，该发热体材料具有合适的电阻率，且力学性能优异。
本发明提供了一种低温卷烟用发热体材料，制备原料包括绝缘陶瓷和金属；
所述金属与绝缘陶瓷的质量比为4:1～1:4。

将所述压坯和金属混合后进行熔浸处理，抛光，得到发热体材料。
在本发明中，所述熔浸处理的温度为1200～2000℃，时间为1～10h，真空度≥1Pa。
本发明优选对绝缘陶瓷粉末和发泡剂进行酸洗和超声波清洗，以去除表面的氧化膜及污染物。在本发明中，所述发泡剂优选自碳酸氢铵、碳酸钙和十二烷基磺酸钠中的一种或多种。所述发泡剂占绝缘陶瓷粉末体积的10～25％。本发明通过控制发泡剂的用量控制孔隙的体积分数，从而控制渗入金属数量，实现对电阻率的控制。具体实施例中，所述发泡剂占绝缘陶瓷粉末体积的10％、25％、15％、或20％。发泡剂在熔浸过程中烧损或分解。
在本发明中，球磨时的球料比为(5：1)～(10:1)；球磨的转速为200～500rpm；球磨的介质为高纯乙醇，球磨的时间为2～12h。
本发明优选将球磨后的混合粉末在真空干燥箱中烘干；烘干的温度为60～120℃。具体实施例中，烘干的温度为60℃、80℃、90℃、或120℃。
在本发明中，模压成型的压力为200～400MPa，模压成型的时间为30～120s。具体实施例中，模压成型的压力为200MPa、或400MPa、或300MPa、或；时间为30s、或120s、或60s。
本发明优选将压坯和金属放入陶瓷坩埚内再进行熔浸处理；所述压坯和金属的质量比为6:4、或7:3、或1:1、或1:4。
本发明优选在真空烧结炉中进行熔浸处理；所述熔浸处理的温度为1200～2000℃，时间为1～10h，真空度≥1Pa。具体实施例中，所述熔浸处理的温度为1200℃、或2000℃、或1800℃、或1600℃；时间为1h、或10h、或8h；真空度为1Pa、或2Pa、或3Pa。
本发明提供了一种上述技术方案所述发热体材料或上述技术方案所述制备方法制备的发热体材料在制备低温卷烟发热体元件中的应用。
对于发热体元件而言，合适的电阻值，大概在0.5～1.5Ω之间，优选0.8Ω左右。不同尺寸的元件所需的合适电阻率是不一样的。一般而言，合适的电阻率为2000μΩ·cm左右，强度不能低于300MPa。
