Kinetic Modelling and Finite Element Simulation of Natural Rubber Non-isothermal Vulcanization

摘要

On the basis of kinetic equations constructed in the isothermal vulcanization of natural rubber (NR), a new numerical computation expression of cure degree under non-isothermal conditions is established by the incremental method. The numerical simulation of the vulcanization stage in injection molding processes of NR is performed by the finite element method, and then the time and position-dependent changes in the cure degree are analyzed numerically. The simulation results are consistent with the results described in the previous literatures. The valuable vulcanization characteristics obtained in the simulation will help engineers in the optimum design of processing conditions.
