Description

电磁屏蔽材料
技术领域
本发明涉及一种电磁屏蔽材料。
背景技术
现有技术中，电磁屏蔽材料都是将具有电磁屏蔽的金属丝网熔固于玻璃中。然而，这种电磁屏蔽材料不能弯曲和卷绕，且不易裁切，导致在需电磁屏蔽的场合或在对芯片、设备等进行电磁兼容性测试时使用不便。
发明内容
鉴于以上内容，有必要提供一种使用方便的电磁屏蔽材料。
一种电磁屏蔽材料，包括一基材层及一熔固于所述基材层内的金属丝网，所述基材层由柔性且具有电磁屏蔽功能的材料制成，所述金属丝网由多根金属丝编织成网格状，所述基材层由聚乙烯、聚酯、尼龙、聚氯乙烯中的一种或几种制成。
上述电磁屏蔽材料通过使用聚乙烯等柔性材料制作基材层，并在该基材层的一侧面设有一胶粘层，使用时，只需将该电磁屏蔽材料粘贴至电磁屏蔽处即可，如此使得该电磁屏蔽材料使用及裁切时非常方便。
附图说明
图1是本发明电磁屏蔽材料较佳实施方式的剖视图。
图2是本发明电磁屏蔽材料的较佳实施方式的示意图。
主要元件符号说明
胶粘层 10
基材层 20
金属丝网 30
镶边金属丝 300
如下具体实施方式将结合上述附图进一步说明本发明。
具体实施方式
下面结合附图及较佳实施方式对本发明作进一步详细描述：
请参考图1及图2，本发明电磁屏蔽材料的较佳实施方法包括一基材层20、一设置于所述基材层20一侧面上的胶粘层10及一熔固于所述基材层20内的金属丝网30。所述基材层20由柔性且具有电磁屏蔽特性的材料制成，如聚乙烯、聚酯、尼龙、聚氯乙烯等，所述金属丝网30的材料可采用导电性良好的金属或者合金，如金、银、铜、铝等。所述金属丝网30由多根金属丝编织成纵横相交的网格状。所述金属丝网30相对的两侧边上设有镶边金属丝300作为预留接地接口。一般而言，该镶边金属丝300较位于该两镶边金属丝300之间金属丝的直径略宽。该电磁屏蔽材料设有胶粘层，可随意将该电磁屏蔽材料粘贴于需要屏蔽的物体上。该电磁屏蔽材料制造完成后使用卷状封装，方便储存、运输及使用。本实施方式中，金属丝网的网孔呈矩形，其他实施方式中，网孔还可根据需要制成其他形状，如圆形、菱形及蜂巢形等。
根据电磁屏蔽的原理可知，对一定波长的电磁波进行屏蔽时，屏蔽材料的孔径应不大于该波长的1/2倍。本实施方式中，假定需要屏蔽30G赫兹的电磁辐射波长。构成所述金属丝网30的金属丝的直径不大于0.1毫米，且任意两根相邻的平行金属丝之间的距离不大于5毫米，即任意两根相邻的平行铜丝之间的距离应不大于该30G赫兹的电磁辐射的波长的1/2倍。本实施方式中，所述金属丝网30相对的两侧边上的镶边金属丝300的直径为1毫米。
使用时，裁切该电磁屏蔽材料，将裁切的电磁屏蔽材料带胶粘层10的一侧面粘贴至电磁屏蔽处（图未示），并将该电磁屏蔽材料上的镶边金属丝300接地。如此，由于该电磁屏蔽材料的金属丝网30上任意两根相邻的金属丝之间的距离不大于该30G赫兹的电磁辐射波长的1/2倍，且所述金属丝网30通过该镶边金属丝300接地，所以该电磁屏蔽材料具有很好的电磁屏蔽功能。
上述电磁屏蔽材料通过使用聚乙烯等柔性材料制作基材层，并在该基材层的一侧面设有一胶粘层，使用时，只需将该电磁屏蔽材料粘贴至电磁屏蔽处即可，如此使得该电磁屏蔽材料使用及裁切时非常方便。
