Vulcanization Kinetics of Starch Xanthate /Natural Rubber Composite

Abstract:

The starch xanthate/natural rubber (SX/NR) composite was prepared by directly mixing and co-coagulating NR latex and the modified starch paste with carbon bisulfide. The vulcanization kinetics of NR and SX/NR composite were investigated by using a rubber process analysis (RPA). The mechanism of SX/NR composite vulcanization was similar to that of pure NR. The values t₀ and t_dis of XS/NR composite were shorter than that of NR, and the activation energy E₁ for the induction period was smaller. The activation energies E₂ and E₃ for the curing period were smaller than that of NR.
