Rheological Studies on Curing Kinetics of Epoxy Resins for Electroplating in Slush Mold Preparation
摘要
Abstract
The curing process of epoxy resins for electroplating is important for slush mold preparation. This process was studied using rheological methods in this study. The results show that bisphenol-A epoxy resins react with polyamine and the degree of curing increases with time. The degree of curing increases from being slowly to being fast and finally become slowly again to stabilized. Meanwhile, the temperature has an important effect on curing rates. As the reaction temperature increases, the curing rate of the two-component epoxy resin speeds up, while the curing rate declines as the reaction temperature decreases. Therefore, the time that can be used to handle the epoxy resin for making mold becomes longer. The curing kinetic equation for the epoxy resin is established, and the relationship between curing rate and reaction temperature is also obtained. The activation energy for the curing process is acquired. It is concluded that the curing kinetics of the epoxy resin follows the Kamal autocatalytic kinetic model.关键词
