Abstract

Cure kinetics of DGEBA(diglycidyl ether of bisphenol A)/MDA(4,4'-methylene dianiline)/GN(glutaronitrile) system with and without HQ(hydroquinone) as a catalyst was studied by Kissinger equation and Fractional life method. The activation energy of the system with HQ was somewhat lower and the pre-exponential factor of that was higher by about 30% than those of the system without HQ. As 1.25phr of HQ was added, reaction rates increased about 1.8 times.

촉매로 작용하는 HQ의 첨가에 따른 DGEBA/MDA/GN계의 경화반응 속도론 변화를 Kissinger equation과 Fractional life법에 의해 연구하였다. HQ가 첨가된 계가 첨가되지 않은 계보다 활성화 에너지는 약간 감소하였고, pre-exponential factor 값은 30% 정도 증가하였다. 그리고, HQ(1.25phr)가 첨가됨으로 인해 반응속도는 1.8배 정도 증가하였다.
