【Abstract】 The effect of antistatic zinc oxide whisker on the vulcanized,mechanical and electrical properties of heat vulcanized(HTV)silicone rubber was investigated.The results showed that antistatic zinc oxide whisker could accelerate vulcanization reaction in the initial stage but delayed in the later stage,in the vulcanization process of silicone rubber,and improve minimum torque(M L) and maximum torque(M H) of compound.The tensile strength,tensile elongation,surface resistivity and volume resistivity of the vulcanized silicone rubber were reduced while its hardness was increased.更多还原
