Description

一种导电橡胶
技术领域
本发明涉及一种高分子材料领域，具体为一种导电橡胶。 
背景技术
随着现代科技的高速发展，各类电子设备的广泛应用，其电磁波对电子设备及人的身体健康的影响突显出来，因此电磁波屏蔽装置更加广泛应于多种电子设备，其电磁波屏蔽的稳定性和精确度也越来越高，这需要提供柔软性能好的电磁屏蔽材料，如导电橡胶。 
导电橡胶通常是指体积电阻在10的9 次欧姆厘米以内，由于橡胶是优良的绝缘体，体积电阻大于 10 的 14 次左右。导电炭黑填充的导电橡胶，体积电阻通常可保持在几千欧，由于现有的配方中使用了单一的乙炔炭黑，其抗拉强度只能达到 12Mpa，远远不能满足实际的需要。 
发明内容
本发明是的目的是提供一种电阻率小，导电率高，屏蔽效果好的导电橡胶。 
本发明是通过以下技术方案来实现： 
一种导电橡胶，所述的导电橡胶包括以下重量份数的组份：天然橡胶50~80份，导电材料2~5份，硬脂酸1~5份，氧化锌1~10份，防老剂1~3份，硫化剂1~5份，催化剂0.5~2份，石墨1~5份。
进一步地，所述导电材料为玻璃镀银颗粒、铝镀银颗粒、银颗粒一种或几种。 
进一步地，所述防老剂为N-苯基-β-萘胺。 
进一步地，所述硫化剂为N，N-间苯撑双马来酰亚胺。 
进一步地，所述催化剂为铂化合物。 
本发明的有益效果是：采用上述配方制备的导电橡胶，具有良好的屏蔽效果，较大抗拉强度，而且具有很强的耐老性，适合生产加工的需要。 
具体实施方式
下面结合实施例对本发明做进一步说明。 
实施例1 
一种导电橡胶，所述的导电橡胶包括以下重量份数的组份：天然橡胶50份，铝镀银颗粒2份，硬脂酸1份，氧化锌3份，N-苯基-β-萘胺1份，N，N-间苯撑双马来酰亚胺1份，铂化合物0.5份，石墨1份。
实施例2 
一种导电橡胶，所述的导电橡胶包括以下重量份数的组份：天然橡胶65份，铝镀银颗粒3份，硬脂酸3份，氧化锌5份，N-苯基-β-萘胺2份，N，N-间苯撑双马来酰亚胺2份，铂化合物1份，石墨3份。
实施例3 
一种导电橡胶，所述的导电橡胶包括以下重量份数的组份：天然橡胶80份，铝镀银颗粒5份，硬脂酸5份，氧化锌10份，N-苯基-β-萘胺3份，N，N-间苯撑双马来酰亚胺5份，铂化合物2份，石墨5份。
采用上述配方制备的导电橡胶，具有良好的屏蔽效果，较大抗拉强度，而且具有很强的耐老性，适合生产加工的需要。 
以上所述，仅是本发明的实施例而已，并非是对本发明作任何其他形式的限制，而依据本发明的技术实质所作的任何修改或等同变化，仍属于本发明所要求保护的范围。
