Description

一种含有石墨纤维的耐磨滤清器滤纸
技术领域
本发明涉及滤清器技术领域，尤其涉及一种含有石墨纤维的耐磨滤清器滤纸纸。
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***、润滑***和燃烧***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，提供一种含有石墨纤维的耐磨滤清器滤纸纸。
本发明是通过以下技术方案实现的：
一种含有石墨纤维的耐磨滤清器滤纸纸，其是由下述重量份的原料制得：
稻壳1-2、板栗壳2.3-3.5、薄片状氧化硅1-2、针状阔叶纤维10-20、琼脂1-2、六偏磷酸钠1-3、亚麻浆30-40、竹浆50-60、活性炭1-3、乙二胺1-3、烷基苯酚聚氧乙烯醚1-4、聚丙烯酰胺1-2、水溶性酚醛树脂1-2、羧乙基纤维素钠0.3-0.5、羧甲基淀粉钠0.2-0.4、硬脂酰胺0.1-0.2、石墨纤维1-2、芳纶纤维1-3，三聚氰胺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。
所述的一种含有石墨纤维的耐磨滤清器滤纸纸，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）稻壳、板栗壳混匀后，进行蒸汽***，***水蒸气压力为0.05-0.3Mpa，***时间为1-3s，爆出物经脱水处理后干燥，得干燥粉备用；
（5）按重量份混合亚麻浆、竹浆和干燥粉；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。
（2）本发明采用蒸汽***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“***”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。
（3）本发明配方合理，成纸过滤性能高，通过添加石墨纤维等耐磨物质，提高了滤纸的耐磨性能。石墨纤维分子结构已石墨化、含碳量高于99%的具有层状六方晶格石墨结构的纤维，通过添加该物质能够有效增加本发明的耐磨性。琼脂增加了纸张的光滑度，使得本发明有一定的光泽度，成色好。
