Description

一种透气性好的滤清器滤纸
技术领域
本发明涉及滤清器技术领域，尤其涉及一种透气性好的滤清器滤纸。
背景技术
发动机有空气、机油、燃油三种滤清器，一般称作“三滤”。它们分别担负发动机进气系统、润滑系统和燃烧系统中介质的过滤。空气滤清器的型式有二种，即干式和湿式。干式空气滤清器是通过一个干式滤芯，(如纸滤芯)将空气中的杂质分离出来的滤清器。
轻型车(含轿车、微型车)所用的空气滤清器一般为单级，过滤材料为滤纸或非织造布。在额定空气体积流量下，滤芯的原始滤清效率应不低于99.5%。重型车由于工作环境恶劣，它的空气滤清器必须是多级的。第一级为旋流式预滤器(如叶片环、旋流管等)，用于滤除粗大颗粒杂质，过滤效率在80%以上，第二级细滤是微孔纸滤芯(一般称作主滤芯)，其过滤效率达99.5%以上。
使用低价格的滤纸制作滤芯，因其滤纸孔径大、均匀性差、过滤效率低，不能将对有害的杂质进行有效滤除，危害身体健康。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种透气性好的滤清器滤纸。
本发明是通过以下技术方案实现的：
一种透气性好的滤清器滤纸，其是由下述重量份的原料制得：草浆40-50、针叶木浆10-20、PAE湿强剂0.2-0.4、纳米钾长石粉1-2，丙烯酸酯乳液胶黏剂1-2、磷酸二氢铵0.5-1，磷酸三甲苯酯0.8-1.2、矿棉纤维10-12、硬脂酸3-4、聚乙二醇2-4.腰果壳油1-2、麻杆1-2、花生壳1-2、皂荚糖胶1-2、三聚氰胺0.1-0.2、苯丙乳液15-20、橘子皮2-4、榴莲壳4-8，甘蔗皮5-6、椰棕1-2、锯木屑3-5、柠檬酸0.02-0.05、硝酸锌0.1-0.2、硝酸银0.2-0.5。
所述的一种透气性好的滤清器滤纸，制备方法包括以下步骤：
（1）橘子皮、榴莲壳、甘蔗皮混匀后，加水相当于上述原料0.6-1倍的水，混匀后，厌氧发酵1-2天后，洗净，风干，干燥，粉碎至粒径范围在500-1000um之间，再紫外辐照30-60min后，得生物粉备用；辐照紫外线波长为254nm，辐射剂量为0.5-2kJ/m2，照射2-3分钟；
（2）柠檬酸加适量水，配制成浓度为2-5%的柠檬酸溶液后，加入生物粉，在40-60℃下搅拌0.5-1h后，再加入硝酸锌、硝酸银，搅拌均匀后，过滤，用蒸馏水洗涤滤渣，至滤液呈中性，将滤渣加入浓度为2-3%的碳酸氢钠溶液中，在30-50℃下搅拌0.5-3h，过滤，用蒸馏水洗涤滤渣，至滤液呈中性，滤渣于50-70℃下干燥后，即得生物负载抗菌粉备用；
（3）苯丙乳液与三聚氰胺混匀后，再加入生物负载抗菌粉混匀后，得浸渍液备用；
（4）麻杆、花生壳混匀后，进行蒸汽爆破，爆破水蒸气压力为0.05-0.3Mpa，爆破时间为1-3s，爆出物经脱水处理后干燥，得干燥粉备用；
（5）按重量份混合草浆、针叶木浆、矿棉纤维和干燥粉；然后放入碎浆机碎解，加水适量水，得到固含量为4-6%的浆料，再加入除浸渍液外其他剩余原料，搅拌并继续碎解得混合浆料，经疏解机疏解后，再磨浆，磨浆后所得浆料经过加水调浆，至固含量3-5%后按照常规造纸工艺抄纸，成型压榨、干燥即得成型纸备用；
（6）成型纸置于浸渍液中浸渍2-3h，再用压力辊除去过量的浸渍液；在160-200℃下恒温烘干后整理，即得。
本发明的优点是：（1）本发明配方合理，成纸过滤性能高，透气性佳，添加了麻杆、花生壳等物质，孔隙度，有利于透气的同时容尘量高，环保健康，使用效果佳。
（2）本发明使用浸渍液，起到了多级过滤的效果，弥补了滤纸纤维间部分孔洞孔径较大的缺陷，提高了滤纸纤维间孔洞孔径的均匀性，强化了筛滤效应。同时加入了生物负载抗菌粉，生物载体可将抗菌剂负载,缓慢释放,抗菌作用强,持效性好、具广谱性以及与加工制品相容好的优点,对各种细菌、霉菌都具有很好的杀灭抑制作用、对环境无任何污染。利用橘子皮、榴莲壳、甘蔗皮作为生物载体，变废为宝。
（3）本发明采用蒸汽爆破技术，植物细胞中的纤维为木素所粘结，与高温、高压蒸汽作用下，纤维素结晶度提高，聚合度下降，半纤维素部分降解，木素软化，横向连结强度下降，当充满压力蒸汽的物料骤然减压时，孔隙中的气剧膨胀，产生“爆破”效果，将原料撕裂为细小纤维，制得的纤维制浆有高得率、无污染的特点。。
