Abstract:
      The effect of mixing field conditions on the properties of the SSBR/NR compound was investigated. The results showed that,with the increase of rotor speed,the Mooney viscosity of compound changed little,minimum torque was increased first and then decreased,the maximum torque was increased,the scorch time was shortened,the optimum cure time changed little;the Shore A hardness,tensile strength and elongation at break of vulcanizate were increased,the tear strength was decreased,and the Payne effect of the compound was strengthened first and then weakened. With the increase of initial mixing temperature,the Mooney viscosity,minimum torque and maximum torque of the compound were increased,the scorch time and optimum cure time were shortened,the modulus at 300%,tensile strength,elongation at break and tear strength of vulcanizate decreased in general,and the Payne effect of the compound was significantly enhanced.
