Description

一种海泡石复合纸、其制备方法和用途
技术领域
本发明涉及加热非燃烧产品领域，具体涉及一种海泡石复合纸、其制备方法和用途。
背景技术
加热非燃烧卷烟(HnB)是一种新型烟草制品，主要通过热源加热烟弹发烟，在非燃烧状态下产生供消费者吸入的烟雾，减少了常规卷烟中燃烧和热裂解产生的有害烟气成分，且不产生侧流烟气。
加热非燃烧的发雾量是影响加热非燃烧抽吸感受的重要因素，而加热不燃烧烟草制品的受热温度较低(200-500℃)就常常带来加热不燃烧制品烟雾释放量低、香气不足等问题。目前，大部分的方案都采用增加雾化剂负载量的方式，但加热不燃烧烟草原料的负载雾化剂的能力有限，加入到烟草原料中的雾化剂很容易被烟草原料吸收且被因机械挤压流失。
发明内容
本发明以海泡石作为发雾剂载体，并将其和非烟草纤维浆料混合抄造成纸张。所述纸张可明显提高发雾剂负载量，在此基础上制得的新型卷烟能够实现快速、均匀、大量释放烟雾的效果，提高受众感官体验，对于丰富加热非燃烧卷烟载发雾剂形式具有较为重要的意义。
