根据中医学理论,中医内病外治是在基本理论指导下,主要运用中药的各种不同的制剂形式,通过机体、肌表、孔窍、穴位,作用于经络、气血、脏腑、局部病灶,从而达到祛除机体内在疾患、调整和提高机体机能的一种治疗方法。
通过利用中药制剂对聚氨酯软质泡沫进行改性,使用软质泡沫具有某种中医理疗功能。由于内病外治的内容相当丰富,因此将这种具有某种中医理疗功能泡沫通过多种具体治疗手段更广泛的应用到市场中去。
发明内容
本发明的目的在于提供一种含有中药成分的具有中药理疗功效的软质聚氨酯泡沫及其制作方法。
本发明的技术解决方案是:
一种具有中药理疗功效的软质聚氨酯泡沫,包括聚氨酯软质泡沫,其特征是:聚氨酯软质泡沫中分布有中药组分;所述中药组分为针对感冒或失眠的中药组分。
一种具有中药理疗功效的软质聚氨酯泡沫的制作方法,其特征是:包括下列步骤:
(1)将中药研磨成粗末,与部分多元醇混合,并浸泡在其中待用;(2)再将发泡剂及催化剂、泡沫稳定剂、阻燃剂、颜料中的一种或几种依次与另一部分多元醇充分搅拌混合;(3)将步骤(1)和(2)中制得的组合料与异氰酸酯组分手工搅拌或通过高压或低高发泡机混合发泡;(4)发泡料快速反应,在连续生产线或箱模中固化成形,得产品。
产品的中药制剂重量百分比为10%-20%。
所述的异氰酸酯组分为甲苯二异氰酸酯、二苯甲烷二异氰酸酯、液化MDI或者聚合多苯基多异氰酸酯。
以异氰酸酯和多元醇为原料制备软质聚氨酯泡沫的异氰酸酯指数为80-150。
产品的平均密度在15-120kg/m3。
所述催化剂为胺类和/或金属盐类催化剂,胺类催化剂为包括五甲基二乙烯三胺、N,N-二甲基环己胺、三乙烯二胺、三乙胺、双二甲胺基乙基醚中的一种或几种的叔胺类催化剂;金属盐类催化剂为异辛酸钾、甲酸季铵盐、醋酸钾、二月桂酸二丁基锡、辛酸亚锡和油酸钾的一种或几种。
所述的发泡剂为物理发泡剂或化学发泡剂;其中所述物理发泡剂为水,所述化学发泡剂为二氯甲烷、1,1-二氯-1-氟乙烷、1,1,1,3,3-五氟丙烷、1,1,1,3,3-五氟丁烷中的一种或几种。
所述的中药是针对感冒预防的中药,配方为:荆芥、防风、桑叶、白菊花、薄荷叶、苏叶、苍术、白芷、鹅不食草地各60重量份,羌活、川中,山柰各30重量份,白檀香10重量份。
所述的中药是针对失眠的中药,配方为:白菊花、录磁石、合欢花、夜交藤各100重量份,石菖蒲、生龙齿、远志各60重量份,朱染灯心、公丁香各30重量份,白檀香20重量份;对多梦的症状,另加生龙骨100重量份。
本发明的有益效果在于:
本发明以聚氨酯软质泡沫为载体,通过共混发泡技术将中药材固化在泡沫中,从而使得药效更加持久,聚氨酯软质泡沫具有仿生结构,拥有上万个开放的超细微的蜂窝气孔,就像天然形成的透气层和渗水层,具超强的吸湿、渗透和通用排气透气能力。同时,由于聚氨酯软质泡沫具有很好的热可塑料,能轻易通过高温磨具加工定型,更便于与其他材料复合,并保持基泡沫各项优良性能。
此外,其中所含中药都采用多种纯天然药材进行精心研制而成,成本低廉;发明泡沫中所含的中药药物性温和,无刺激性,对病人机体没有任何伤害。
“异氰酸酯指数”指异氰酸酯基的数目除以异氰酸酯-反应基因的数目得到的商再乘以100。
下面结合实施例对本发明作进一步说明。
