Description
本实用新型涉及一种防辐射手机壳。
关于手机辐射人体有没有害的马拉松式的争论从来没有停止过。手机幅射对人体健康影响的研究不够重视，故还处于起始阶段，但随着手机移动通讯的更新换代，5G的使用频率的升高，波长的变短，发射接收功率的增加以及数以十亿手机的使用，手机使用低龄化人群的快速扩展，再加上人们使用、携带手机的不良习惯，如长时间的通话、放于裤袋中、床头手机充电等，致使手机防幅射不得不予面对。
目前广泛使用的手机在使用时产生的电磁幅射，对使用者产生了一定的伤害是越来越得到认同，随着移动通讯2G 3G 4G 5G的发展，其使用频率越来越高，功率越来越强，其幅射强度有增无减，通过研究的深入，幅射伤害的证据表现更多地浮现。
现有的手机防辐射通常采用手机防辐射贴片、贴纸、贴膜，是将金属或导电涂料喷涂在贴片、贴纸、贴膜上，使其表面形成电磁反射屏蔽，并该贴片、贴纸、贴膜局部贴在手机某处，实际效果极差，达不到防幅射目的，其工作原理是与防辐射孕妇服装原理一样，阻隔屏蔽，反射，防护。也有专利文献中记载手机壳内设置金属纤维网袋将手机完全装入袋中，将手机完全屏蔽，以此达到防辐射的效果，其原理同手机防辐射贴膜、防辐射服装的作用相同，该方式的防辐射由于金属屏蔽阻碍无线电波的发射进而对手机收发信号会产生很大影响。因此，我们开发一款不影响手机性能的防辐射产品很有必要。
实用新型内容
本实用新型提供一种防辐射手机壳，在不影响手机收发信号的性能下，降 低手机辐射对人体的损害。
本实用新型采用以下技术方案：
防辐射手机壳，包括：高分子基体和石墨材料，高分子基体注塑成手机壳体的形状，石墨材料形成的薄片被压注在高分子基体的夹层中。
一方面，所述石墨材料为若干层石墨烯。
优选地，所述石墨烯的层数至少为2层。
优选地，若干层石墨烯形成的薄片随手机壳体包裹住手机。
另一方面，所述石墨材料为石墨。
再一方面，所述石墨材料为富勒烯。
优选地，所述石墨材料的厚度为0.2mm-2mm。
优选地，所述薄片随手机壳体包裹住手机。
相比较传统手机防辐射，采用金属纤维网对手机电磁波的屏蔽，并没有改变手机辐射电磁波的物理属性，容易发生泄漏，仍然会对人体产生手机辐射的危险，且由于金属纤维网会对手机信号造成屏蔽进而影响手机通话性能。本实用新型将石墨材料形成的薄片注塑进手机的夹层中，将手机收发信号的电磁能转换成热能释放掉，由于石墨烯是由单层碳原子排列成六边形晶格的一种异形体，它不会对手机信号进行阻碍或屏蔽，改变了手机辐射电磁波的物理属性，变换成热能释放掉，因此更加安全，解决了手机辐射电磁波泄漏的问题，降低对人体的损害。

本实施例防辐射手机壳是在高分子介质中添加电磁损耗性物质(吸波材料)，利用电磁能转换热能的原理，吸收辐射转化成热能释放掉，碳材料—石墨烯具有良好的电磁屏蔽、吸波性能，厚度在0.2mm-2mm至少2层至多层石墨烯高密度的材料对手机除屏幕外的包裹，有效的屏蔽吸波,频率范围从30HZ到5000MHZ,很好地将手机的电磁幅射降低至40μW/cm
2以下。
测试手机防辐射实验，测距3cm，实验结果如下：
由上述防辐射实验中可以看出，防辐射贴膜对辐射效果几乎作用为零，本专利的防辐射手机壳的辐射效果为安全值40μW/cm
2以下，对人体无损伤。
另一个实施例中，防辐射手机壳包括高分子基体和石墨，高分子基体注塑成手机壳体1的形状，石墨形成的石墨片2被压注在高分子基体的夹层中。优选地，石墨片随手机壳体包裹住手机3，石墨的厚度0.2mm-2mm。
另一个实施例中，防辐射手机壳包括高分子基体和富勒烯，高分子基体注塑成手机壳体1的形状，富勒烯形成的富勒烯片2被压注在高分子基体的夹层中。优选地，富勒烯片随手机壳体包裹住手机3，富勒烯的厚度0.2mm-2mm。
