Description

一种高效低阻纤维复合过滤材料的生产方法 技术领域
本发明涉及一种过滤材料的生产方法，具体涉及一种阻力≤38Pa、过滤效率≥99.97％的空气过滤材料的生产方法。
背景技术
随着现代工业技术的迅速发展，生产生活对环境空气洁净度要求越来越高，许多生产环境、居住环境要达到高等级的空气洁净度，所选用的过滤材料就需要有高效率、低阻力的过滤性能。目前高效、亚高效等打褶过滤器大部分还在使用玻纤滤纸为主要过滤材料，这种滤纸虽然具有对微细粒子高效捕集、易打折加工等优点，但因为滤纸中纤维结构密集，且纤维间孔隙小且少，导致过滤阻力大。
为了改善玻璃滤纸的缺陷，人们开始选用丙纶熔喷非织造布作为滤材，由于丙纶熔喷非织造布的纤维细、结构蓬松、孔隙多，并且其比表面积大，密度小，过滤性能优越，并且耐化学腐蚀性好，尤其适于工业滤材，广泛应用于电子、制药、食品、饮料、化学等行业，但传统工艺生产的丙纶非织造布身厚度薄，比较柔软，刚性差，不适合褶皱加工。
目前，也有将丙纶熔喷非织造布与玻璃纤维滤纸复合滤纸，如专利CN101352631公开了一种由熔喷非织造布与玻璃纤维纸复合而成的新型过滤材料，这样的复合过滤材料在整体强度方面有了一定的改善，但作为骨材的玻璃纤维纸由于其本身的脆性，抗褶皱性依旧不是很好。
聚丙烯过滤材料被广泛应用于空气过滤和室内净化机、口罩、空调风口等产品，其具有寿命长、表面积大、风阻低、能效高等特点。但是，按照行业标准的检测方法，目前工艺所生产的无纺布，其过滤效率≤99.95％时，其阻力一般≥120Pa。因此，如何生产一种同时具有高过滤效率及低阻力或是无阻力的无纺布，是目前行业内亟待解决的问题。
