Abstract
The kinetic model of liquid silicone rubber hydrosilation is determined with measuring apparatus for vulcanization extent. The definition of increment of vulcanization ratio is introduced, so the numerical computation expression of the full dose of vulcanization ratio is obtained. The foundational control equation of the vulcanization temperature field accompanied by reaction heat is derived. Then two types of thermal boundary conditions are analyzed. The implementation procedures of the finite element simulation are described in detail. Finally, the finite element simulation software of hot vulcanization process of moldable silicone rubber is designed, and the rationality of the simulation theory and algorithm is verified by one typical engineering example and its hardness test as well as its engineering application.
