【Abstract】 The characteristics of dehydrogenation liquid silicone rubber crosslinking reaction and foaming reaction were analyzed by using Alfa RPA200 P,and the kinetic equations of crosslinking reaction and foaming reaction were got through studying the isothermal kinetic process of the rubber crosslinking and foaming reaction at different temperatures.The result showed that,the crosslinking and foaming of rubber had typical autocatalytic characteristic,so that the autocatalytic model can describe the dynamic process very well.更多还原
