Description
技术领域
本发明涉及橡胶，特别涉及涉及用于衬套的导电橡胶。
背景技术
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
本发明所要解决的技术问题是提供一种抗拉强度能够大于25Mpa的导电橡胶。
本发明解决技术问题的技术方案为：一种导电橡胶，含有以下物质及重量份：
优选的导电橡胶，含有以下物质及重量份：
所述的防老剂的型号为BLE。
所述的防焦剂的型号为CTP-80。
本发明的制备方法与现有的导电橡胶的制备方法相同，N，N’-二(2，6-二异丙基苯基)碳二亚胺与N-环己基-2-苯并噻唑次磺酰胺同时加入。
本发明中，中超高耐磨碳黑N220的用量过多或过少，都不能完成本发明。
本发明与现有技术相比，所制成的导电橡胶为深黑色胶料，混炼胶流动性好，易于硫化加工，合格率高；并且易于与金属粘结性；橡胶从最大分型处传导电在500V时，从橡胶到金属不大于500kΩ；橡胶抗拉强度≥25Mpa，扯断伸长率≥550％、耐老化性能好，适合生产导电衬套和导电橡胶减震产品。
