초록

에폭시/무수물 시스템에 반응을 촉진시키기 위해서 삼차아민을 사용하였다. 에폭시수지와 무수물 경화제에 대한 반응촉진제의 영향과 에폭시수지, 무수물 경화제, 그리고 반응촉진제가 cjar된 온합물의 경화반응을 알아보기 위해서 thermogravimetric analysis, differential scanning calorimetry 그리고 Fourier transform-infrared를 이용하였다. 이들 실험결과를 토대로, 삼차아민 반응촉진제를 첨가한 에폭시/무수물 시스템에 대한 경화반응 메카니즘을 제안하였고, 이에 따라 반응속도식을 구하였다.

In order to accelerate cure reactions of an epoxy/anhydride system, a tertiary amine was used. Thermogravimetric analysis, differential scanning calormetry, and Fourier transform-infrared were used to examine the effects of accelerators aganist epoxy resins and anhydride hardeners and to investigate cure reactions for an accelerators-added epoxy/anhydride system. Based on experimental results, the mechani는 of cure reaction were proposed and the kinetics of cure reaction calculated.

Keywords:cure reaction;accelerator;cure mechanism;kinetics
