Description

一种复合硅藻土空气净化剂及其制备方法
技术领域
本发明涉及空气净化领域。更具体地,涉及一种复合硅藻土空气净化剂及其制备方法。
背景技术
近年来,随着社会经济的快速发展和生活水平的不断提高,室内装饰装修成为一种时尚。但装饰装修材料、办公用品、家居生活用品含有许多有害污染物质,甲醛、氨、氡、挥发性有机物以及颗粒物等,对人体健康的影响日益受到人们的重视。目前对于室内空气污染的治理方法包括过滤法、触媒法、臭氧净化法、低温等离子净化法和吸附净化法等,其中吸附净化法是应用最广泛的一种方法。多数净化材料的缺点是吸附效率低,饱和速度快,致使需要经常更换;或者成本较高,有些会带来二次污染。硅藻士壳体上微孔密集、堆密度小、比表面积大,因而具有较强的吸附力和过滤性能。
因此,以硅藻士为原料制备一种吸附效率高、能有效吸附有害物质的空气净化剂具有重要意义。
发明内容
本发明的一个目的在于提供一种吸附效率高、能有效吸附有害物质的空气净化剂;
本发明的另一个目的在于提供上述空气净化剂的制备方法。
为达到上述目的,本发明采用下述技术方案:
一种复合硅藻土空气净化剂,由以下各组分制成:吸附剂、活化剂、强氧化剂、粘合剂、纳米粒子粉和去离子水。
优选的,各组分的重量份为:吸附剂20-50份、活化剂15-25份、强氧化剂30-40份、粘合剂10-18份、纳米粒子粉1-3份和去离子水10-20份。
进一步,所述吸附剂为精制硅藻土,所述精制硅藻土的SiO2含量在93%以上;
所述活化剂为柠檬酸;
所述强氧化剂为高铁酸钠或高铁酸钾的任意一种;
所述粘合剂为聚乙烯醇;
所述纳米粒子粉为纳米二氧化钛。
一种复合硅藻土空气净化剂的制备方法,包括以下步骤:将各组分混合均匀后,注入成型模具造粒、过筛,即得。
本发明空气净化剂以硅藻土的为载体,在强氧化剂的作用下,使得甲醛、苯等有害气体氧化分解,同时,在活化剂和纳米粒子粉的作用下,活性不减,持续时间长。
本发明的有益效果如下:
本发明制备的复合硅藻土空气净化剂,可净化室内空气,对空气中有害物质的吸附分解效果好,使用时间长,是用于室内,车内等封闭空间的环境净化和各种空气净化器的理想选择材料。制备方法工艺简单易于产业化规模生产。
具体实施方式
为了更清楚地说明本发明,下面结合优选实施例对本发明做进一步的说明。本领域技术人员应当理解,下面所具体描述的内容是说明性的而非限制性的,不应以此限制本发明的保护范围。
实施例1一种复合硅藻土空气净化剂的制备
一种复合硅藻土空气净化剂的制备,包括以下步骤:称取各组分,即精制硅藻土2.5kg、柠檬酸1.5kg、高铁酸钠3.0kg、聚乙烯醇1.0kg、纳米二氧化钛0.1kg和去离子水1.0kg,将各组分混合均匀后,注入成型模具造粒、过筛,将制成的成型颗粒干燥,装入包装物中密封。
实施例2一种复合硅藻土空气净化剂的制备
一种复合硅藻土空气净化剂的制备,包括以下步骤:称取各组分,即精制硅藻土5.0kg、柠檬酸2.5kg、高铁酸钾4.0kg、聚乙烯醇1.8kg、纳米二氧化钛0.3kg和去离子水2.0kg,将各组分混合均匀后,注入成型模具造粒、过筛,将制成的成型颗粒干燥,装入包装物中密封。
实施例3一种复合硅藻土空气净化剂的制备
一种复合硅藻土空气净化剂的制备,包括以下步骤:称取各组分,即精制硅藻土3.5kg、柠檬酸2.0kg、高铁酸钠3.5kg、聚乙烯醇1.4kg、纳米二氧化钛0.2kg和去离子水1.5kg,将各组分混合均匀后,注入成型模具造粒、过筛,将制成的成型颗粒干燥,装入包装物中密封。
对比例1一种复合硅藻土空气净化剂的制备
一种复合硅藻土空气净化剂的制备,包括以下步骤:称取各组分,即精制硅藻土2.5kg、柠檬酸1.5kg、二氧化氯3.0kg、聚乙烯醇1.0kg、纳米二氧化钛0.1kg和去离子水1.0kg,将各组分混合均匀后,注入成型模具造粒、过筛,将制成的成型颗粒干燥,装入包装物中密封。
对比例2一种复合硅藻土空气净化剂的制备
一种复合硅藻土空气净化剂的制备,包括以下步骤:称取各组分,即精制硅藻土5.0kg、柠檬酸2.5kg、二氧化氯4.0kg、聚乙烯醇1.8kg、纳米二氧化钛0.3kg和去离子水2.0kg,将各组分混合均匀后,注入成型模具造粒、过筛,将制成的成型颗粒干燥,装入包装物中密封。
实验例1复合硅藻土空气净化剂对有害气体甲醛、苯的去除率的测定
考察实施例1-3和对比例1、2制备的复合硅藻土空气净化剂对于有害气体甲醛、苯的吸附能力,结果见表1。
表1复合硅藻土空气净化剂去除有害气体甲醛、苯的吸附情况
从表1中可以看出,本发明实施例1-3制备的复合硅藻土空气净化剂均能有效的去除有害气体甲醛、苯,去除率均达到了99.5%以上,大大提高了空气净化效果。而对比例1和对比例2中用二氧化氯分别代替了实施例1的高铁酸钠和实施例2中的高铁酸钾,使得其对甲醛、苯的去除率大大降低。
另外,对比例1和2制备的复合硅藻土空气净化剂相比于实施例1-3挥发性较强,具有明显的异味,使用寿命较短。
显然,本发明的上述实施例仅仅是为清楚地说明本发明所作的举例,而并非是对本发明的实施方式的限定,对于所属领域的普通技术人员来说,在上述说明的基础上还可以做出其它不同形式的变化或变动,这里无法对所有的实施方式予以穷举,凡是属于本发明的技术方案所引伸出的显而易见的变化或变动仍处于本发明的保护范围之列。
