Abstract
一种椰壳碳介孔碳纳米管空气滤料的制备方法，属于空气净化滤料制备领域。本发明将椰壳碳、介孔空心碳纳米球与羧甲基纤维素钠混合后加入去离子水，在搅拌机的搅拌作用下形成配料。配料倒入造粒机中，均匀挤出介孔空心碳纳米球碳柱，在60～180℃之间干燥1～12小时，制得介孔空心碳纳米球空气滤料。其中其中碳纳米管加入量为总质量的5‑20wt％，羧甲基纤维素钠的加入量为总质量的5‑30wt％；去离子水与混合粉末的体积比为(0.5‑1)：1。以羧甲基纤维素钠为粘结剂制备介孔空心碳纳米球碳柱能够大幅度提高吸附效率，有效去除酸性或碱性以及VOC(挥发性有机物)等有害气体，达到净化空气的目的，本发明可用于各种作业场所(例如：服务器机房、新风系统等)的有害气体去除，简单实用，使用寿命长。
Description
技术领域
本发明涉及介孔碳纳米管空气滤料的配方及制备方法，具体是利用介孔碳纳米管制备空气净化用滤料，属于空气净化滤料制备技术领域。
背景技术
目前大气污染的日益严重，雾霾的频繁出现，严重影响到人们的正常工作、学习、生活以及身体健康。现有生活中人们采用的防空气污染的方式一般就是戴口罩、室内放活性炭等方式。但是戴口罩只能起到简单的过滤作用，而大部分活性炭孔径难以调控，孔径单一，大部分为“无效”的大孔。目前添加碳纳米管的空气净化滤料，多采用多壁碳纳米管，管壁为石墨化结构的碳，无介孔。高比表面积活性炭具有多孔结构，能够吸附有机物和无机物，具有吸附容量大，吸附速度快的特点，是一种优质高效的吸附剂，广泛应用与环保等行业。
发明内容
本发明的目的在于，提供一种椰壳碳介孔碳纳米管空气滤料的制备方法；该方法包括以下步骤：
(1)将椰壳炭、介孔碳纳米管与羧甲基纤维素钠按一定质量比例混合；其中碳纳米管加入量为总质量的5-20wt％(质量百分比)，羧甲基纤维素钠的加入量为总质量的5-30wt％(质量百分比)；
(2)往步骤(1)中加入一定体积的去离子水，去离子水与混合粉末的体积比为(0.5-1)：1，在搅拌机的搅拌作用下，得到配料；
(3)将步骤(2)的配料倒入造粒机中，均匀挤出介孔碳纳米管碳柱，碳柱的直径4mm，长度2-5cm；
(4)将步骤(3)得到的碳柱，在70～150℃之间干燥1～12小时，制得介孔碳纳米管空气滤料。
进一步地，在步骤(1)中，介孔碳纳米管的壁厚5-20nm，管内径5-100nm，外径20-200nm，管的长度为2-10μm，管壁介孔为蠕虫状介孔，介孔直径2-5nm。
图1为介孔碳纳米管的扫描电镜形貌照片，可看出介孔碳纳米管具有均匀的长度，长度约2-10μm介孔碳纳米管进一步放大的透射电镜(图2)可以看出介孔碳纳米管的壁厚约10nm，管壁上有大量蠕虫状的孔，其介孔直径约1-3nm，图3为以介孔碳纳米管为原料，制备出的介孔碳纳米管碳柱，碳柱的直径4mm，长度2-5cm。图4为介孔碳纳米管空气滤料NOx气体的吸附性能测试结果，当NOx气体进口浓度为1000ppb时，介孔碳纳米管空气滤料可快速有效将NOx气体浓度降至2ppb左右。
本发明的优点和积极效果是：利用介孔碳纳米管本身具备的多级孔结构，以及高比表面积(600m2/g)，在椰壳碳中，加入一定比例的介孔碳纳米管，以羧甲基纤维素钠为粘结剂，制备介孔碳纳米管碳柱能够大提高吸附效率，可以有效去除酸性或碱性以及VOC(挥发性有机物)等有害气体，达到净化空气的目的。与只使用椰壳炭的空气滤料相比，加入的介孔碳纳米管由于具备多级孔结构，能够有效吸附有害气体的有效孔数量更多，从而大大提高有害气体的吸附率和吸附速度；本发明可用于各种作业场所的有害气体去除，简单实用，使用寿命长；
