Description

一种用于吸附甲醛的生物环保制剂
技术领域
本发明属于环保技术领域，具体涉及一种用于吸附甲醛的生物环保制剂。
背景技术
甲醛，化学式HCHO，式量30.03,又称蚁醛。无色气体，有特殊的刺激气味，对人眼、鼻等有刺激作用,气体相对密度1.067，液体密度0.815g/cm³，熔点-92℃，沸点-19.5℃。易溶于水和乙醇。水溶液的浓度最高可达55%，通常是40%，称做甲醛水，俗称福尔马林（formalin），是有刺激气味的无色液体。室内空气污染已成为多种疾病的诱因，而甲醛则是造成室内空气污染的一个主要方面。甲醛污染问题主要集中于居室、纺织品和食品中。居室装饰材料和家具中的胶合板、纤维板、刨花板等人造板材中含有大量以甲醛为主的脲醛树脂，各类油漆、涂料中都含有甲醛。
甲醛对健康危害主要有以下几个方面：a、刺激作用：甲醛的主要危害表现为对皮肤黏膜的刺激作用，甲醛是原浆毒物质，能与蛋白质结合、高浓度吸入时出现呼吸道严重的刺激和水肿、眼刺激、头痛。b、致敏作用：皮肤直接接触甲醛可引起过敏性皮炎、色斑、坏死，吸入高浓度甲醛时可诱发支气管哮喘。c、致突变作用：高浓度甲醛还是一种基因毒性物质。实验动物在实验室高浓度吸入的情况下，可引起鼻咽肿瘤。d、突出表现：头痛、头晕、乏力、恶心、呕吐、胸闷、眼痛、嗓子痛、胃纳差、心悸、失眠、体重减轻、记忆力减退以及植物神经紊乱等；孕妇长期吸入可能导致胎儿畸形，甚至死亡，男子长期吸入可导致男子精子畸形、死亡等。
目前，去除甲醛等有害气体的主要方法是通风和物理吸附；很多厂家生产吸附剂，但是效果不理想，而且不够环保，容易二次污染；因此，开发一种用于吸附甲醛的生物环保制剂尤为重要。
发明内容
为了克服现有技术中甲醛等有害气体的吸附剂效果差，而且容易产生二次污染等技术问题，本发明提供了一种用于吸附甲醛的生物环保制剂，该制剂吸附效果好，环保无污染。
为实现上述目的，本发明所采用的技术方案如下：
一种用于吸附甲醛的生物环保制剂，其由如下重量份的原料制备而得：
凸凹棒土1-2份，甲壳素1-2份，十二烷基磺酸钠2-3份，高岭土2-3份，竹炭纤维3-4份，石英砂4-5份，山豆根4-5份，硅藻土5-7份，海泡石6-8份，水稻秸秆8-10份、活性炭15-20份，水25-35份；
本发明还公开了上述生物环保制剂的制备方法，具体包括如下步骤：
步骤1）称取原料：按照重量份称取各原料备用；
步骤2）研磨：将海泡石和石英砂混合，研磨成粒径为100um的粉末；
步骤3）搅拌保温：将凸凹棒土、甲壳素、十二烷基磺酸钠以及步骤2）制备的粉末依次添加到水中，搅拌均匀，然后加热至65℃，保温10min，得到复混物1；
步骤4）粉碎研磨：将水稻秸秆和山豆根混合，然后用粉碎机粉碎，最后研磨至10-50um粉末，最后与竹炭纤维混合，得到复混物2；
步骤5）煅烧：将硅藻土和高岭土混合，然后置于在煅烧炉中煅烧3h，煅烧温度为900℃，取出，冷却至室温，最后与活性炭混匀，得到复混物3；
步骤6）烘干粉碎：将将复混物1、复混物2以及复混物3混合，搅拌均匀，然后置于80℃烘干，最后粉碎成粉末即得。
优选地，所述竹炭纤维的长度为100－1000um。
本发明取得的有益效果主要包括以下几个方面：
本发明生物环保制剂去除甲醛等有害气体效果好，环保无污染；本发明采用十二烷基磺酸钠对凸凹棒土、甲壳素了改性，提高其吸附容量；采用煅烧硅藻土和高岭土的工艺，大大提高了吸附能力；本发明提取农作物废弃秸秆和山豆根，提高了吸附效果；竹炭纤维以及山豆根等还能去除环境中的霉菌，一举两得；本发明生物环保制剂原料配伍合理，制备工艺简单可行，成本低廉，使用面积广，且对人体无害，健康安全。
