Non-isothermal Curing Kinetics of Modified Amine-Epoxy Asphalt

Abstract

The curing reaction characteristics of modified amine-epoxy and epoxy asphalt system under different heating rates were analyzed by differential scanning calorimetry (DSC). The relationship between curing degree and activation energy during the curing reaction is studied. The Kissinger equation was used to calculate the apparent activation energy of the reaction, and the rate constant and the reaction order of the curing reaction were fitted by Kamal equation. The results showed that the curing reaction was a typical self-catalytic reaction, the apparent activation energy of epoxy system and epoxy asphalt system were 34.95 kJ/mol and 42.02 kJ/mol, respectively. Meanwhile the curing reaction rate constant and order of the epoxy asphalt system were less than those of the epoxy system. The curing reaction rate of epoxy curing system was contracted by introduced asphalt. Furthermore, the late of curing reaction was dominated by diffusion control.
