초록

가전제품용 플라스틱 재료의 열화 거동과 신뢰성을 고찰하기 위해 열분해에 따른 동역학적 매개변수를 결정하기 위하여 동역학적 열중량 분석기법을 사용하였고, 촉진 열화시험을 수행하였다. 또한, 플라스틱 재료의 내후성을 고찰하고자 제논 아크 광원을 사용하여 촉진 열화시험을 하였고, 가속 열화시험후 시료의 색차를 컬러 아이 3010 색차분석기를 이용하여 측정하였다. 재료는 중량감소율이 증가함에 따라 열분해 활성화 에너지도 증가하는 경향을 보였다. 플라스틱 재료의 열분해에 관한 기술은 Kim-Park 법이 가장 효과적인 분석법으로 나타났다. 플라스틱 재료는 빠른 열화를 진행시키는 자외선에 아주 민감하게 반응하였다.

The thermal degradation behavior and reliability analysis were investigated using dynamic thermogravimetric analysis (TGA) and accelerated degradation test (ADT) to characterize the dynamic parameters related to thermal degradation of plastic meterials for household electric appliances. In addition, the weathering of the plastic were performed by ADT using Xenon arc, and the color difference of the samples after ADT were measured with Color Eye 3010 spectrophotometer. The activation energy for thermal degradation of the samples increased with increasing the rate of weight loss. The Kim-Park method was found to be more effective analysis in describing thermal degradation of plastic meterials. Plastic materials were very sensitive to ultra-violet rays in faster degradation.

Keywords:activation energy;plastics;reliability;thermal degradation
