Preparation and Performance of Nickel Carbon Conductive HTV Silicone Rubber by Dispensing Molding
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 op-timal 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/cm3,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.
