Description

一种复合型空气过滤材料的静电纺丝液配方
技术领域
本发明属于空气过滤材料领域。
背景技术
在工业、农业、服务业的快速发展的同时，生态环境也不断恶化，对人类健康造成了巨大威胁。人们对洁净空气质量的认识不断提高、对于洁净空气的质量要求也越来越高。然而现有常见的空气过滤材料对于当今复杂、多样的污染物和污染源，不免显得单一和无能为力。如何有效过滤甚至隔绝环境空气污染物二氧化硫、二氧化氮、一氧化碳、臭氧、颗粒物(粒径小于等于10微米或粒径小于等于2.5微米)(参考文献：《环境空气质量标准》(GB 3095-2012))，提高和改善环境空气质量，成为当务之急。
常见过滤材料是基于木浆纸或者无纺布(毡)作为过滤介质，其过滤效率取决于过滤介质自身的每单位平方米克重，基本上可以归纳为每单位平方米克重越大，其过滤效率越高。但即便是亚高效级别的空气过滤，其额定风量下的初阻力(ΔPi)/Pa≤120、额定风量下的终阻力(ΔPi)/Pa＝240(参见文献：《空气过滤器》(GB/T 14295-2008))，其过滤效率需要开启有源电动风机实现，即电能消耗将直接增加使用成本。且当容尘量达到一定值和使用一段时间后必须更换，使用寿命受到极大的限制；其更换后视作废弃物，对于回收和再利用造成困难，增加了自然环境的负担。
随着材料科学和制备手段的进步，特别是受合成纤维的启发，使纤维过滤材料的强度、透气性、阻燃性等关键指标得到的进一步提升；同时将功能性的材料进行复合，从而获得更加优异的性能。
静电纺丝技术是聚合物溶液在高压静电作用下进行喷射拉伸而获得纳米尺度纤维的纺丝方法，利用静电纺丝法制备的直径几十或几百纳米的超细纤维，应用于空气过滤领域，为高精度空气过滤材料的规模化生产提供了崭新的途径。静电纺丝法中纺丝液的单一组份、多组份的配备，也将空气过滤材料的综合性能和适用范围进行了较大的提升，为有效过滤甚至隔绝环境空气污染物拓展了更为广阔的空间。
