Description

一种电磁屏蔽塑料
技术领域
本发明属于功能塑料领域，具体涉及一种电磁屏蔽塑料。
背景技术
随着现在精密仪器的发展，电磁屏蔽材料越来越凸显其重要性，由于精密仪器的各零部件之间不能产生相互干扰，这就需要各部件外需要使用电磁屏蔽材料进行屏蔽，现在通用的是使用铜箔或者银箔进行屏蔽，但是，材料价格较高，而且材料重量较大，造成仪器的质量增加，也会增加仪器的成本。现在的电磁屏蔽塑料采用层状结构，在塑料片材中间增设屏蔽层，加工工艺复杂，而且屏蔽效果较差。
发明内容
本发明的目的是提供一种电磁屏蔽塑料，提高电磁屏蔽的效果，而且材料较轻，强度较大。
本发明通过以下技术方案实现：
一种电磁屏蔽塑料，按重量计包括85-95%塑料基体尼龙66、3-5%石墨烯填充物、1-3%炭黑、0.2-0.8%热稳定剂硝酸铅、0.2-1%增塑剂邻苯二甲酸二丁酯、0.1-0.5%防紫外线剂二苯甲酮。
将上述材料混合均匀，使用双螺杆挤出机混炼、造粒，然后使用注塑机进行加工成型。
本发明的有益效果：本发明通过在尼龙66塑料基体中加入石墨烯，石墨烯电阻率只约10-6 Ω·cm，比铜或银更低，为世上电阻率最小的材料，而且质量很轻，在尼龙66中分散均匀，屏蔽对电磁屏蔽效果好。而且成本低，加工成型方便。
具体实施方式
实施例1
一种电磁屏蔽塑料，按重量计包括93%塑料基体尼龙66、3.2%石墨烯填充物、2.2%炭黑、0.6%热稳定剂硝酸铅、0.5%增塑剂邻苯二甲酸二丁酯、0.5%防紫外线剂二苯甲酮。将上述材料混合均匀，使用双螺杆挤出机混炼、造粒，然后使用注塑机进行加工成型。本材料的屏蔽频率0.25-200MHz，在50MHz频率下，对电磁场减弱99.2%，使电子元件见相互干扰的能力降低到极小值，基本不产生相互干扰。
实施例2
一种电磁屏蔽塑料，按重量计包括93%塑料基体尼龙66、4%石墨烯填充物、2%炭黑、0.2%热稳定剂硝酸铅、0.6%增塑剂邻苯二甲酸二丁酯、0.2%防紫外线剂二苯甲酮。将上述材料混合均匀，使用双螺杆挤出机混炼、造粒，然后使用注塑机进行加工成型。
在500Hz磁场下，使用本电磁屏蔽材料可是磁场轻度衰减99.6%。远远高于其他产品。
实施例3
一种电磁屏蔽塑料，按重量计包括90%塑料基体尼龙66、5%石墨烯填充物、3%炭黑、0.5%热稳定剂硝酸铅、1%增塑剂邻苯二甲酸二丁酯、0.5%防紫外线剂二苯甲酮。将上述材料混合均匀，使用双螺杆挤出机混炼、造粒，然后使用注塑机进行加工成型。
