摘　　要：以加成型硅橡胶为基胶、镍碳颗粒为导电填料,添加偶联剂、增粘剂、含氢硅油制得热硫化镍碳导电硅橡胶。探讨了硅橡胶的较佳配方并测试了产品性能,结果表明:较佳配方为加成型硅橡胶100份、镍碳颗粒A 150份、三异硬脂酰基钛酸异丙酯偶联剂1.5份、增粘剂1份、含氢硅油3份。该配方制得的硅橡胶表面电阻为29.47 mΩ、附着力为23.66 N,密度为1.93 g/cm^(3)、邵氏A硬度为65、拉伸强度为1.21 MPa、断裂伸长率为119%,在双“85”老化1000 h后电阻基本保持稳定,可满足市场对点胶成型导电硅橡胶性能的基本需求。The nickel carbon conductive HTV silicone rubber was prepared by additional silicone rubber as the base rubber,nickel carbon particles as conductive fillers,with coupling agent,thickening agent,and hydrogen containing silicone oil.The optimal formula for silicone rubber was explored and its performance was tested.The results showed that the optimal formula was that 100 parts of additional cured silicone rubber,150 parts of nickel carbon particle A,1.5 parts of TTS coupling agent,1 part of tackifier and 3 parts of hydrogen containing silicone oil.The silicone rubber by this formula has the surface resistance of 29.47 mΩ,the adhesion of 23.66 N,the density of 1.93 g/cm^(3),Shore A hardness of 65,the tensile strength of 1.21 MPa,the elongation at break of 119%,and the resistance remains stable after 1,000 hours of double"85"aging test,which can meet the basic requirements for the conductive silicone rubber.
