Description

一种功能性艾灸片及其制备方法
本申请要求于2021年12月31日提交中国专利局、申请号为CN202111674439.9、发明名称为“一种功能性艾灸片及其制备方法”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及艾灸用药技术领域,尤其涉及一种艾灸片的制备方法、一种功能性艾灸片及其制备方法。
背景技术
艾灸是利用艾叶/艾绒制成的艾灸条、艾灸柱或艾灸片,产生的艾热刺激人体穴位或特定部位,通过激发经气的活动来调整人体紊乱的生理生化功能,从而达到防病治病目的的一种治疗方法。艾灸具有操作简单、成本低廉,效果显著等诸多优点。
传统方法制作艾灸片时,首先利用艾草制备艾绒,接着以艾绒为原料,在磨具中冲压成型。冲压成型时,原料只能使用艾绒,不能直接使用艾叶,由于不同艾绒原料难以混合均匀,导致冲压成型过程中以艾绒称重的方式控制艾灸片产品厚度时,易造成艾灸片产品厚度难以控制,艾灸片产品质量均一性较差。
发明内容
有鉴于此,本发明提供了一种艾灸片的制备方法、一种功能性艾灸片及其制备方法,本发明提供的方法制备的艾灸片厚度容易控制,质量均一稳定。
为了实现上述发明目的,本发明提供以下技术方案:
本发明提供了一种艾灸片的制备方法,包括以下步骤:
将艾草原料在水中进行碎解分散,得到艾草纤维水分散液,所述艾草原料包括艾叶和/或艾绒;
将所述艾草纤维水分散液脱水成型,得到艾草纤维湿基片;
将所述艾草纤维湿基片湿法压制定型,得到艾灸片。
优选的,所述艾草纤维水分散液的质量百分浓度为0.5~12%。
优选的,所述艾草纤维水分散液中的艾草纤维的尺寸为 100μm~3mm。
优选的,所述湿法压制定型的保压压力为0.5~2bar,所述湿法压制定型的保压时间为5~180s。

优选的,所述湿法压制定型还包括将定型产品干燥,所述干燥的温度≤42℃。
本发明提供了一种功能性艾灸片,包括若干艾灸片层和若干功能物质层,所述艾灸片层和功能物质层层叠设置;所述功能性艾灸片的至少一个侧面设置为艾灸片层,所述艾灸片层由上述技术方案所述制备方法制备得到。
优选的,所述功能性艾灸片为三明治结构,包括依次层叠设置的第一艾灸片底层、若干功能物质芯层和第二艾灸片表层。
本发明提供了上述技术方案所述的功能性艾灸片的制备方法,包括以下步骤:
(1)将艾草原料在水中进行碎解分散,得到艾草纤维水分散液,所述艾草原料包括艾叶和/或艾绒;
(2)将所述艾草纤维水分散液脱水成型,得到艾草纤维湿基片;
(3)将第一功能物质水分散液置于所述艾草纤维湿基片表面,将所述艾草纤维湿基片和设置于所述艾草纤维湿基片表面的所述第一功能物质水分散液共同脱水成型,在所述艾草纤维湿基片上形成第一功能物质湿料层,得到复合湿坯;
(4)将所述复合湿坯湿法压制定型。
优选的,形成所述第一功能物质湿料层后,在进行所述湿法压制定型之前,还包括:以所述艾草纤维水分散液替换步骤(3)中的第一功能物质水分散液重复步骤(3)和/或以第二功能物质水分散液替换步骤(3)中的第一功能物质水分散液重复步骤(3),在所述第一功能物质湿料层表面组坯,得到复合湿坯。
本发明提供了一种艾灸片的制备方法,包括以下步骤:将艾草原料在 水中进行碎解分散,得到艾草纤维水分散液,所述艾草原料包括艾叶和/或艾绒;将所述艾草纤维水分散液脱水成型,得到艾草纤维湿基片;将所述艾草纤维湿基片湿法压制定型,得到艾灸片。本发明提供的制备方法首先将艾草原料碎解分散得到艾草纤维水分散液,相比于干法碎解和混料,液体中的艾草纤维混合的更加均匀,且分散液中的艾草纤维在水分散液中表面能够形成氢键,增强艾草纤维之间的结合强度,经脱水成型得到的艾草纤维湿基片的均匀性和密实度增加,最后经过湿法压制定型,由于水介质的存在能够使艾草纤维湿基片受压更加均匀,从而最终得到的艾灸片厚度容易控制,质量均一稳定,易于大批量生产,效率高,克服了干法冲压成型难以精确计量,产品均一性和稳定性差,生产效率低的问题。
且本发明提供的制备方法制备的艾灸片密实度高,强度高,不掉粉,也克服了现有艾绒和/或艾叶干法冲压成型产品强度低,易掉粉,冲压成型的艾灸片还需要外层包覆一层无纺布的包裹层,否则掉粉严重,没办法直接用的缺陷。
本发明提供的制备方法采用湿法压制定型,避免干法成型过程中粉尘以及固体悬浮物等污染问题。
本发明提供的制备方法采用艾草纤维水分散液脱水成型,分散液中的水能够限循环使用,不存在水污染问题。
本发明提供的制备方法具有普遍性,对艾草原料没有要求,用途广泛。
