一种亚麻复合纤维过滤材料
技术领域
本发明涉及一种过滤材料，尤其是涉及空气过滤材料。
背景技术
对于空气过滤技术的主要是过滤掉空气中的污染源，而污染源主要是指微尘和细菌二大类。一般通过空气过滤器来过滤掉室内一定空间环境的空气中的污染源；通过口罩、防毒面具来过滤进入鼻腔和肺部的空气中的污染源。目前空气过滤技术主要采用过滤分离方法：通过设置不同性能的过滤器，除去空气中的悬尘埃粒子和微生物，也即通过滤料将尘埃粒子捕集截留下来，以保证送入风量的洁净度要求。它所用的滤料为较细直径的纤维，既能使气流顺利通过，也能有效地捕集尘埃粒子。
现有技术的过滤材料普遍存在吸附微尘和细菌效果不佳，吸附持续时间不长的问题。
发明内容
本发明所要解决的问题是，针对上述现有技术中的缺点，提出创新方案，尤其是一种能够有效解决现有过滤材料吸附微尘和细菌效果不佳，吸附持续时间不长的问题的方案。
为解决上述问题，本发明采用的方案如下：一种亚麻复合纤维过滤材料，其特征在于，其主要原料包括亚麻纤维、六方晶系氮化硼、聚酯纤维和玻璃纤维；
取聚酯纤维加入10%-30%的氢氧化钠溶液中，保持溶液温度在50-80摄氏度，对聚酯纤维进行碱减量处理，然后取出烘干，制成聚酯纤维束；
取六方晶系氮化硼加入去离子水，使用超声波震荡，形成六方晶系氮化硼的均相混合液A；
将亚麻纤维加入混合液A中，并降温至0摄氏度，并向其中加入氢氧化钠、尿素，然后持续搅拌20-30分钟，制得混合液B；
将混合液B在零下15摄氏度的温度下存放1-4小时，然后取出在室温下结冻，并搅拌30-40分钟，制得亚麻纤维和六方晶系氮化硼形成的均相混合液C；
将混合液C喷射如高速搅拌的盐酸溶液中出去多余的氢氧化钠，得到亚麻纤维与六方晶系氮化硼复合纤维，并用去离子水冲洗至冲洗液的pH值达到7，用烘箱将复合纤维烘干，得到干燥的复合纤维；
取石灰水上清层，并向其中加入干燥的复合纤维和活性炭粉，然后放入高速搅拌机中搅拌20-50分钟，形成改性复合纤维；
玻璃纤维放入酸性蚀刻液中浸润2-7分钟，进行表面处理；所述酸性蚀刻液为浓度为15%的KClO3和浓度为40%的H2SO4的混合液，形成改性玻璃纤维；
将改性复合纤维和改性玻璃纤维交叉缠绕设置在聚酯纤维束上，形成亚麻复合纤维过滤材料。
进一步，根据上述设计方案所述亚麻复合纤维过滤材料，所述加入混合液A中的氢氧化钠、尿素和亚麻纤维的重量比例为3:2:3。
进一步，根据上述设计方案所述亚麻复合纤维过滤材料，所述氢氧化钠、尿素和亚麻纤维加入混合液A后搅拌30分钟。
进一步，根据上述设计方案所述亚麻复合纤维过滤材料，所述混合液B在零下15摄氏度的温度下存放时间为4小时。
进一步，根据上述设计方案所述亚麻复合纤维过滤材料，所述混合液B结冻后搅拌时间为40分钟。

进一步，根据上述设计方案所述亚麻复合纤维过滤材料，所述玻璃纤维放入酸性蚀刻液中浸润时间为5分钟。
本发明的技术效果如下：本发明公开了一种过滤材料，尤其是涉及空气过滤材料，其主要原料包括亚麻纤维、六方晶系氮化硼、聚酯纤维和玻璃纤维。本发明的过滤材料具有很强的通透性，且其过滤性能优异。本发明制得的过滤材料的原料易得，因此本发明的过滤材料造价低廉，并且其工作环境要求低、吸附过滤性能强，适用于办公室、卧室等各种场所。本发明的亚麻复合纤维过滤材料具有抗静电、耐高温、耐酸碱、使用安全性好等优点。
