摘要
Abstract
The cure reaction of epoxy NC-3000L and phenolic aldehyde resin xy-lok system resin catalyzed by triphenylphosphine was studied in both isothermal and dynamic conditions by means of differential scanning calorimeter (DSC). The results show that before the cure extent of 80%, the cure reaction is controlled by chemical kinetics and accords with Kamal selfcatalytic kinetical model. When the cure extent is beyond 80%, the cure reaction alters to diffusion controlling as main mode. The equations of cure reactive kinetics before and after 80% of the cure exetnt are established, respectively. The activity energy of the reaction under dynamic cure condition is 75.04 kJ/mol, which is obtained by Ozawa method.关键词
