Description

一种颗粒型加热卷烟用生物基固件材料及其制备方法 技术领域
本发明属于新型烟草制品技术领域，尤其涉及的是一种颗粒型加热卷烟用生物基固件材料及其制备方法。
背景技术
随着经济文化水平的提升，越来越多的人们更加注重身体的健康，开发新型的烟草制品势在必行。颗粒型加热卷烟是新型烟草制品的重要形式之一。颗粒型加热卷烟区别于目前市售的加热不燃烧卷烟产品，采用烟草颗粒作为释烟物质，烟雾量充足、释烟连续性好，感官质量优异，配方优化调整空间大。但是如何将烟草颗粒封装在烟支中，在加热与抽吸过程中不产生掉落与吸入是烟支生产关键工艺技术问题。
用于阻隔烟草颗粒的固件材料是颗粒型加热卷烟的重要组成之一。目前是将耐高温塑料固件作为中间段阻隔材料，但塑料制品是不可降解材料并且耐热性不够好，在加热抽吸过程中会发生软化熔融，不仅不能起到有效的阻隔作用，还会释放异味，严重降低了烟气品质和抽吸体验，使用后丢弃在环境中不易降解，对环境产生污染。石油能源作为全球消耗量最大的不可再生能源，在人类加速社会经济发展的同时被大量消耗和日益枯竭，致使人们面临着环境污染和资源短缺的危机。使用生物质材料可以有效的起到可持续发展和保护环境的作用。
因此，研究新型的固件材料具有重要意义。
发明内容
本发明的目的在于克服现有技术的不足，提供一种颗粒型加热卷烟用生物基固件材料及其制备方法，旨在使其在烟支中具有较好阻隔和增香的效果。
本发明为实现目的，采用如下技术方案：
一种颗粒型加热卷烟用生物基固件材料，其特点在于：所述固件材料为竹粉基固件材料，各原料按质量百分比的构成为：竹粉70％～80％，粘合剂10％～15％，增香填料5％～10％，甘油5％～10％，以及占其余原料(即除水以外的其余原料，包括竹粉、粘合剂、增香填料和甘油)总质量80％～100％的水；或者，所述固件材料为可塑性淀粉基固件材料，各原料按质量百分比的构成为：可塑性淀粉80％～95％，增香填料5％～20％。
进一步地，所述粘合剂为生物基的瓜尔胶、海藻酸钠和明胶中的至少一种。
进一步地，所述增香填料为烟末。
进一步地，所述可塑性淀粉是将醋酸淀粉与玉米淀粉、马铃薯淀粉和甘薯淀粉中的至少一种按质量比3：7混合，并加入占淀粉总质量30％～35％的甘油进行熔融共混制备而成。
本发明的固件材料中：竹粉作为纯天然材料，经过与粘合剂和水混合烘干后，可以形成一种具有较强力学性能的材料。同时竹粉在使用过程中也会传递出一种草木灰的香气，具有部分增香的作用。淀粉是天然生物高分子，广泛存在于玉米等植物中，通常情况下淀粉是非热塑性的，其玻璃化温度和熔点都高于其热分解温度，直接加热没有熔融过程，不具备热塑性加工性能，无法使用螺杆挤出机等塑料加工机械进行加工。热塑性淀粉的生产原理是将淀粉分子转化为无序结构，从而形成具有热塑性能的淀粉树脂。将烟末作为增香材料加到固件材料中，可以有效的在加热过程中释放出烟草的香味，掩盖固件材料在加热中可能散发的异味，提升抽吸体验。
本发明所述竹粉基固件材料的制备方法为：按配比将各原料混合后，再经螺杆挤出机混合挤出、裁剪，获得所需形状尺寸的固件材料，最后烘干即得成品；
本发明所述可塑性淀粉基固件材料的制备方法为：按配比将各原料熔融共混均匀后，再经螺杆挤出机混合挤出、裁剪，获得所需形状尺寸的固件材料，最后烘干即得成品。
本发明还公开了上述固件材料的应用，是用作颗粒型加热卷烟的辅材，起到阻隔烟草颗粒和辅助增香的效果。
与现有技术相比，本发明的有益效果体现在：
1、本发明的固件材料是全生物可降解的，丢弃在环境中不会造成污染。
2、本发明的固件材料具有一定的力学强度和较高的热稳定性，在加热后不发生变形和炭化，可以有效的阻隔烟草颗粒掉落，同时添加烟末作为增香材料，提升抽吸的烟气品质。
3、本发明固件材料的制备工艺简单、原料易得，易于工业化生产。且本发明无任何化学溶剂，对环境友好。
