Description
技术领域
本发明涉及吸湿材料技术领域,尤其是涉及一种吸湿组件的制备方法。
背景技术
冰箱储藏室内有冷风循环,所以内部是相对密闭的高湿低温环境。为了长时期保持果蔬的新鲜度而优选将其保存于冰箱冷藏室或者密闭的果蔬盒内,保证果蔬处于高湿度的保存环境。但是过高的湿度会在冰箱冷藏室或果蔬盒内部发生明显的结露现象。严重的凝露会成股流下浸泡果蔬影响其保鲜,同时还会影响用户体验。为了解决该技术问题,通常使用吸湿材料,充分吸收周围环境的水汽,降低相对湿度,保证果蔬具有良好的储存条件。
常用的吸湿材料包括固体干燥剂、液体吸湿剂、复合吸湿材料、吸湿除湿膜等。一般采用氯化钙、氯化锂等易潮解无机盐类作为吸湿材料,材料的吸湿性能好,但是易形成潮解溶液流失,造成质量损失。有机高分子类吸湿材料,储湿容量大,性能稳定,但是吸湿速率差,且不易放湿。复合型吸湿材料将吸湿性能好的无机盐与高分子材料混合使用,虽然不易潮解,但是整体吸湿性能仍然有待改善。而采用溶液蒸发法制备的常规吸湿膜的吸附和脱附速率都比较缓慢,吸湿能力较弱,难以满足实际应用。
发明内容
本发明的目的是为了弥补现有技术的缺陷,提供了一种吸湿组件的制备方法。
本发明制备的吸湿组件,由非织造材料、吸湿复合膜、无尘纸、塑料底膜复合组成。
进一步的,所述非织造材料为亲水性强的水刺布、纺粘布中的一种。
进一步的,所述塑料底膜为微孔PE透气底膜,透湿量范围为500~3000g/m2*24hr(25℃,60%RH)。
其中,吸湿复合膜材料是通过以下技术方案实现的:
S1、将金属盐溶解在无水有机醇溶液中形成混合溶液;
S2、在不断搅拌的条件下,将醇胺类加入到混合溶液中进行反应,制得络合物;
S3、将壳聚糖溶解于去离子水中,制得5~20%的壳聚糖溶液;
S4、将络合物与壳聚糖溶液按照一定比例搅拌2~4h,得到了分散液;
S5、将分散液倒入培养皿中风干24~48h,继续在50~80℃的烘箱中加热1~4h,去除剩余水分,得到吸湿复合膜。
优选的,步骤S1所述金属盐为氯化锌、氯化钴中的一种;无水有机醇溶液为甲醇、乙醇、丙醇中的一种;更优选的,有机溶液为无水乙醇。
优选的,步骤S2所述醇胺类为乙醇胺、二乙醇胺、三乙醇胺中的一种;更优选的,所述醇胺类为乙醇胺。
优选的,步骤S2中,混合溶液中金属盐与醇胺类物质的摩尔比为1∶1-5∶1,更优选的,混合溶液中金属盐与醇胺类物质的摩尔比为2∶1。
优选的,步骤S4中,金属络合物与壳聚糖溶液的体积比为1∶1-1∶5;更优选的,络合物与壳聚糖溶液的体积比为1∶2。
吸湿组件中,所述非织造材料作为亲水导湿层,所述吸湿复合膜作为吸湿储湿层,所述无尘纸作为导湿储湿层,所述塑料底膜作为透湿阻气层。
非织造材料作为亲水导湿层,亲水性强的多孔非织造材料能够迅速导湿,有利于吸湿复合膜进行吸湿,同时对吸湿复合膜起到一定的保护和支撑作用。
吸湿复合膜作为吸湿储湿层,吸湿性能极佳的吸湿复合膜可以迅速吸湿、储湿,防止湿度过大,减少凝露的形成。
无尘纸作为导湿储湿层,可以在吸湿复合膜吸湿过程中,进一步将水分进行传递,有利于吸湿复合膜不断进行吸湿和散湿,同时也起到一定的支撑和保护作用。
塑料底膜作为透湿阻气层,主要在于减少空气和水汽的过分散失,防止湿度过低,造成果蔬等食材的不新鲜。塑料底膜还具有一定的透湿效果,使得吸收的水分可以不断散发。
本发明的有益效果包括:
1.本发明的制备的吸湿复合膜是通过醇胺类有机物与湿感金属盐的不饱和配位制成。湿感盐的吸湿性能好,与醇胺类物质进行配位反应,可以形成具有大量多孔结构的络合物,能够快速吸收大量水分。在配位反应的过程中,通过密度泛函理论计算,计算一个水分子的包埋能,不断调整醇胺类物质和金属盐的摩尔比,可以得到吸湿性能极佳的多孔材料。按照最佳配比制备的金属络合物,具有一个开放的多孔结构,这种结构与硅胶非常相似,但是吸水能力对比硅胶大大提升,并且也高于氯化钙的吸水率。
2.本发明制备的吸湿复合膜具有较强的吸水趋势,所以材料的吸湿速率快,形成的多孔结构使得材料的吸湿容量也高。这是因为当最初的几个水分子被引入时,它们往往在结构中发生羟基化,从而产生较高的结合能。然而,随着材料吸附水分子数量的增加,水的吸收主要是由物理吸附而不是羟基化,这导致了后续吸湿过程中,每一个额外的水分子附着到材料上所需的能量的急剧下降。也就是说,在吸湿过程中,本发明制备的吸湿复合膜吸收一个水分子的能量极低,所以材料具有优越的吸湿性能。
3.壳聚糖具有很强的吸湿性、良好的成膜性和力学性能。与金属络合物混合,作为吸湿复合膜的基础支架,保证了材料具有一定的强度和延展性,进一步提高了材料的吸湿能力。
4.本发明制备的吸湿组件由非织造材料、吸湿复合膜、无尘纸、塑料底膜多种材料组合而成。吸湿复合膜主要发挥快速吸湿的作用,非织造材料和无尘纸起到传湿导湿的作用,并对吸湿复合膜起到保护和支撑的作用,保证了吸湿组件的硬挺度和耐久性。塑料底膜控制着吸湿组件的透气和透湿性能,确保了吸湿组件的长期使用。
