摘要:
In this paper, both isothermal and dynamic differential scanning calotimetry (DSC) are employed to characterize the thermal properties of two commercial epoxy molding compounds designated as EMC-A and EN IC-B respectively. In dynamic curing, the heat flow of uncured powder samples weighting10 +/- 0.5 mg, are measured at the healing rates of 5, 10 and 15 C /min from room temperature to 220 C. The isothermal curing tests are performed under the constant temperatures of 130, 140 and 150 C for 30 min. The experimental results show that compared with EMC-B, ENIC-A has smaller average curing reaction enthalpy and activation energy showing a better moldability. The parameters of autocatalytic Kamal equation for these two ENICs are obtained by the isothermal curing tests and the ruling kinetic model exhibits good agreement with the experimental data generally.
