Abstract:
      In this paper, the effects of sulfur dosage and accelerator dosage on the vulcanization properties, mechanical properties and damping property of natural rubber damping materials were investigated. Non-linear fitting model was used to simulate the curing kinetic reaction. The results showed that the reactivity of chemical bonds in crosslinking precursors was weaken, which was similar to the trend of degradation rate constants of cross-linked bonds with sulfur dosage decreasing. And mechanical properties and damping property were reduced with sulfur dosage decreasing. The influences of chemical reactivity in crosslinking precursors on mechanical properties and damping property were contrary to that of sulfur variables, the trend of degradation rate constants of cross-linked bonds of accelerator dosage was similar to that of sulfur variables.
