现代社会的工厂排放到大气中的污染物种类繁多,性质复杂,有烟尘、硫的氧化物、氮的氧化物、有机化合物、卤化物、碳化合物等。其中有的是烟尘,有的是气体。同时,交通运输燃烧染料也排放出大量有害气体,特别是城市中的汽车,量大而集中,排放的污染物能直接侵袭人的呼吸器官,对城市的空气污染很严重,成为大城市空气的主要污染源之一,汽车排放的废气主要有一氧化碳、二氧化硫、氮氧化物和碳氢化合物等,这些物质危害性很大。
在汽车内部,各种皮革制品会使车内甲醛浓度变高,甲醛的主要危害表现为对皮肤粘膜的刺激作用,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。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。高浓度甲醛还是一种基因毒性物质,高浓度吸入的情况下,可引起鼻咽肿瘤。
发明内容
本发明的主要目的在于提供一种汽车空调滤网及其夹层制备方法,其克服现有技术的不足,有效除去粉尘颗粒,一氧化碳,氮氧化物,甲醛等有害物质,有助于提高车内空气质量,有益于驾驶员和乘客的身体健康。
为达到以上目的,本发明采用的技术方案为:一种汽车空调滤网,包括上层、夹层以及下层,上层为碳纤维层,下层为铝合金层,夹层由吡唑联苯醚钴复合材料和活性炭的摩尔比1~3:1混合制成。
根据本发明的一实施例,吡唑联苯醚钴复合材料和活性炭的摩尔比为2:1。
一种汽车空调滤网的夹层制备方法,包括步骤:
S100将4,4'–二吡唑联苯醚和四水合醋酸钴加入到50%的乙醇水溶液中,其中,四水合醋酸钴浓度为1%~3%,搅拌,得到混合液;
S200将混合液加热至80~100℃,反应3~5小时,冷却至常温加入1%的氢氧化钠溶液,继续加热8-10小时;
S300反应结束后,过滤,以饱和的氯化钠水溶液洗涤滤出物,干燥得到吡唑联苯醚钴复合材料;
S400将所得吡唑联苯醚钴复合材料与活性炭1~3:1混合,加入1%的薄荷烷丙醇溶液,浸泡10~12小时,制得汽车空调滤网夹层。
根据本发明的一实施例,所述步骤S100中的4,4'–二吡唑联苯醚的制备方法,包括步骤:在DMF溶剂下,将4,4'–二溴二苯醚、吡唑、氢氧化钠和硫酸亚铁加热制备4,4'–二吡唑联苯醚,反应温度100℃,反应时间3小时,其中,4,4'–二溴二苯醚、吡唑、氢氧化钠、硫酸亚铁的摩尔比为1:5:8:1。
根据本发明的一实施例,在所述步骤S100中的4,4'–二吡唑联苯醚和四水合醋酸钴之间的摩尔比为1~3:1。
根据本发明的一实施例,在所述步骤S200中氢氧化钠和四水合醋酸钴的摩尔比为1~3:1。
与现有技术相比,本发明的有益效果为:
