Description

一种吸波浸渍胶液和吸波蜂窝及其制备方法
技术领域
本发明涉及复合材料领域,具体而言,涉及一种吸波浸渍胶液和吸波蜂窝及其制备方法。
背景技术
随着现代技术的不断发展,越来越多的电子产品进入到我们的日常生活和工作中,人们对电子产品的依赖度也越来越高,但是它们在给我们的生活带来越来越多的便利的同时,其产生的大量的电磁辐射也对我们的健康造成很大的威胁。例如,在机场,飞机航班因电磁波干扰无法起飞而误点;在医院,移动电话常会干扰各种电子诊疗仪器的正常工作。因此,研究一种能较好地抵挡并削弱电磁波辐射的吸波材料具有十分重要的意义。
此外,在军事上,如果能在飞机、导弹、坦克、舰艇、仓库等各种武器装备和军事设施上涂覆吸收材料,就可以吸收侦察电波、衰减反射信号,从而突破敌方雷达的防区,这是反雷达侦察的一种有力手段,可以减少武器系统遭受导弹和激光武器的袭击。因此,对吸波材料的研究在增强我国的军事能力,提高军队的战斗力方面也具有极其重大的价值。
蜂窝形结构的材料外形与自然界的蜂窝类似,具有独特的六边形结构,能均匀地承受外界施加的力,并且质量较轻,可以在保证足够的强度的同时,最大限度的减轻材料的重量,因此蜂窝形结构的材料是一种重要的基体材料。
在蜂窝形结构上涂覆吸波胶液是制备吸波蜂窝的重要手段之一,它能够满足吸波材料对“厚度薄、质量轻、频带宽、吸收强”的要求,但是现有的蜂窝浸渍工艺是使用电吹风机或者压缩气体吹除蜂窝的格孔壁洞的胶液,很容易导致堵孔现象,严重影响打孔蜂窝质量。
