Description

热固性空气滤纸及其制备方法
技术领域
本发明涉及滤纸技术领域，具体涉及一种热固性空气滤纸及其制备方法。
背景技术
空气滤纸作为空气过滤器滤芯的关键组成部分，其性能决定了空气过滤器的使用效果。随着医药、医疗卫生、电子等行业对厂房洁净度的要求越来越高，对空气过滤器提出了更高的要求。
然而现有的空气滤纸由于采用普通木浆纤维，制成的空气滤纸普遍存在着紧度高、过滤效率低、容灰量低、寿命短等缺点，而且其过滤效率一般都低于90％，且纸制的空气滤纸还普遍存在着固化性差、耐水性不够，当空气湿度改变时，纸张容易产生变形，进而影响过滤的效果。
发明内容
针对现有技术的不足，本发明提供一种耐湿度高、固化性好、寿命长、过滤效果好的热固性空气滤纸，本发明还提供了该空气滤纸的制备方法和应用。
为实现发明目的，本发明采用以下技术方案：
一种热固性空气滤纸，包括原纸和对原纸进行浸渍的浸渍剂，所述的原纸，按重量份数计，包括以下组分：
石膏纤维是硫酸钙的纤维状单晶体，具有高强度，高模量、高介电强度、耐磨耗、耐高温，耐腐蚀、红外线反射性良好、易于表面处理、与高分子聚合物的亲和力强等诸多优良的理化性能。
作为优选，所述的竹纤维为纳米竹纤维，纤维粒径为80～100nm。
作为优选，所述的玻璃纤维为纳米玻璃纤维，纤维粒径控制在100nm以下；玻璃纤维，因经不起打浆，玻璃纤维之间又缺乏粘结和，抄成的纸页很脆弱，但是如果把玻璃丝直径控制在100纳米以下，那么就可以解决玻璃丝的伸缩小、柔软性差而造成的成纸难的现象，有利于纤维的互相交织成形。
作为优选，所述的纤维状粘结剂为包括水溶性PVA纤维、维荣纤维、低熔点聚酯中的一种或两种以上混合物。
作为优选，所述的分散剂包括阴离子聚丙烯酰胺或聚氧乙烯。
作为优选，所述的原纸中的防水剂选自三聚氰胺类树脂、防水浆或脲醛树脂的一种或多种。
作为优选，所述的原纸的定量为140±5g/㎡，厚度为0.45±0.05mm。
所述的浸渍剂，按重量份数计，包括以下组分：
所述的聚乙二醇改性三聚氰胺甲醛树脂是将聚乙二醇和适量水，升温搅拌，加少量乙酸，pH值控制在4.5～6.0之间，缓慢加入部分三聚氰胺，温度保持在95℃以内，反应1.0—1.5h。降低温度，加入剩余三聚氰胺，加甲醛，用NaOH调节pH值为8.0～8.5，并用三乙醇胺保持稳定的pH值环境，温度控制在75—80℃，反应60～75min，检验反应液水容忍度，若达到要求，得到透明无沉淀树脂液。
作为优选，所述的浸渍剂中的润湿剂选自烷基硫酸盐、磺酸盐、脂肪酸或脂肪酸酯硫酸盐、羧酸皂类、磷酸酯的一种或多种。
作为优选，所述的热固性空气滤纸的定量为160±5g/㎡，厚度为0.50±0.05mm。
本发明还涉及上述热固性空气滤纸的制备方法，采取的技术手段为：
一种热固性空气滤纸的制备方法，包括如下步骤：
a将配方量的麻纤维、竹纤维和纤维状粘结剂用打浆机打浆，再经过双盘磨浆机在线打磨得到浆料，打浆浓度为1.98～2.67％，打浆至15～18°SR；
b将配方量的玻璃纤维、石膏纤维、纳米微晶纤维素和水溶性聚乙烯醇纤维加入到步骤a)所得的浆料中形成纸浆浆料；
c将配方量的消泡剂，分散剂，防水剂加入到步骤b的纸浆浆料中，搅拌均匀，得到成浆，浆料浓度为1.58～1.98％；
d将步骤c得到的成浆按常规条件上网抄造及压榨得到原纸；
e配置浸渍剂，将配方量的聚乙二醇改性三聚氰胺甲醛树脂、聚醋酸乙烯酯乳液、聚乙二醇改性酚醛树脂、碳酸锆铵溶液和润湿剂放入反应釜中于70～90℃的温度下进行充分的搅拌，搅拌时间为2～6hr，然后冷却至室温，用50～100目纱布过滤得到浸渍剂；
f将步骤d得到原纸浸渍在步骤e中的浸渍剂中，采用凹版网纹面的辊式涂布方式进行浸渍，控制上胶量为20％±0.5％；
g浸渍后纸样在150℃～160℃循环热风中固化。
