Abstract
The kinetic for two-component silicon rubber formed by addition reaction was studied by the rheological method. The influence of reaction temperature on reaction rate was also explored. The Oscillatory frequency has no influence on the study for the cross-linking process of two-component silicon rubber with rheological method. As the addition reaction going on,the cross-linking degree becomes bigger and the properties of system change from liquid properties dominate to solid properties dominate. With reaction temperature increasing,the cross-linking rate of silicon rubber quickens and less time is needed to finish the cross-linking reaction. Based on the relation between cross-linking velocity and the reaction temperature,the apparent activation energy of system can be obtained. Rheological method is suitable for studying the silicon rubber crosslinking process.
