Description

一种屏蔽隔音材料制备方法
技术领域
本发明涉及一种对电磁波有屏蔽作用的隔音材料的制备方法。
背景技术
人体是一个导体,像所有导体一样,人体受到无线电流和微波辐射后,会产生电流,从而引起人体发热。一般来说,我们所处的空间中的无线电波和微波是比较弱的,引起的发热非常小,完全可以忽略。
太阳所发出的红外线和可见光是自然界中最强的电磁辐射,也是我们所处的环境中最强的电磁辐射源,红外线和可见光可以在人体的表层引起发热。
人体的器官和组织都存在微弱的电磁场,它们是稳定和有序的,一旦受到外界某些频率电磁波的干扰,处于平衡状态的微弱电磁场可能遭到破坏,从而对人体的机能产生影响。高能电磁辐射对人体的伤害尚未来得及自我修复之前再次受到辐射的话,其伤害程度就会发生累积,久之会成为永久性病态或危及生命。对于长期接触高能电磁波辐射的群体,即使功率很小,频率很低,也会诱发想不到的病变,应引起警惕!有科学家经过长期研究证明:长期接受电磁辐射会造成人体免疫力下降、新陈代谢紊乱、记忆力减退、提前衰老、心率失常、视力下降、听力下降、血压异常、皮肤产生斑痘、粗糙,甚至导致各类癌症等;男女生殖能力下降、妇女易患月经紊乱、流产、畸胎等症。
随着社会进步,人们对现有的电磁波屏蔽材料提出了更高的要求,因此,本领域的技术人员积极的研发电磁波屏蔽材料使其具备隔音这一功能。
发明内容
有鉴于现有技术的上述缺陷,本发明所要解决的技术问题是提供一种制备能够屏蔽电磁波且隔音的材料的方法。
为实现上述目的,本发明提供了一种屏蔽隔音材料制备方法,以单壁碳纳米管及玻璃微球作为导电填料,以聚合物树脂作为基体材料,取预先制备的单壁碳纳米管及玻璃微球浸泡在乙醇中,待其完全浸润后取出,将其放入去离子水中,待单壁碳纳米管完全铺展在水面上后,按如下方法之一复合聚合物树脂:
方法一、将银粉、硝酸钡、柠檬酸溶液及去离子水混合均匀后,将溶液放入80℃~350℃水浴中,得到前驱体凝胶,将前驱体凝胶在100℃~300℃烘干后,煆烧1h~24h并随炉冷却;然后将其与单壁碳纳米管贴合固化;
方法二、将单壁碳纳米管及玻璃微球转移到模具中,取银粉体、环氧树脂和聚酰胺树脂用丙酮稀释,混合均匀后,均匀涂在单壁碳纳米管及玻璃微球上,然后再涂一层石墨烯混合体,最后固化;
方法三、将单壁碳纳米管及玻璃微球转移到模具中,以正硅酸乙酯为材料,高硅氧纤维为增强体,采用氧水催化一步法制备氧化硅气凝胶增强隔热材料;将氧化硅气凝胶增强隔热材料与单壁碳纳米管贴合固化;
方法四、将单壁碳纳米管及玻璃微球转移到模具中,通过苯甲碱催化一步法,将正硅酸乙酯和乙醇混合搅拌10min--60min后,加入氨水和去离子水搅拌10min---60min得到溶胶,之后浸渍高硅氧纤维,并直接装入高压釜中进行超临界干燥,待高压釜冷却至室温后,开釜取样将其与单壁碳纳米管贴合固化。
本发明的有益效果是:本发明制备出的材料可以屏蔽电磁波并具有良好的隔音作用。
