초록

ABS/실리케이트 복합체를 clay의 종류 및 함량을 변화시키며 에멀젼 중합을 이용하여 제조하였다. ABS의 화학구조는 적외선분광기(FT-IR)를 이용하여 이중결합 C-H 신축진동 피크(3000 $cm^{-1}$ 근처)의 변화를 통해 확인하였다. ABS/실리케이트 복합체의 열적특성은 시차주사열용량분석기(DSC) 와 열중량분석기(TGA)를 이용하여 관찰하였다. Clay의 종류에 따른 ABS의 유리전이온도에는 큰 변화가 나타나지 않음을 알 수 있었다. TGA에 의한 분해온도는 20A의 함량이 3 wt%인 ABS/20A 복합체에서 가장 높은 값을 나타내었다. 복합체의 실리케이트 분산정도는 X-선회절(XRD)법을 이용하여 측정하였다. ABS/20A 복합체의 실리케이트 분산은 20A 함량에 의존하였고, 함량이 5 wt% 이상 첨가되었을 때 20A의 회절 피크가 나타나는 것을 확인하였다.

ABS/silicate composites with different clay types and compositions were prepared by in situ emulsion polymerization. The chemical structure of ABS was confirmed by the change of C-H stretching peak(near 3000 $cm^{-1}$) in fourier transform-infrared(FT-IR) spectrum. The thermal properties of the ABS/silicate composites were investigated by differential scanning calorimetry(DSC) and thermogravimetric analyzer(TGA). There was no distinct change in glass transition temperature of the ABS/silicate composites with different clay types. TGA curve indicates a dramatic increase in degradation temperature in case of ABS/20A composite with 3 wt% 20A. The silicate dispersion in the composites was measured by X-ray diffraction(XRD). The silicate dispersion in ABS/20A composites depended on the 20A composition. XRD results showed that the diffraction peak of the ABS/20A composite appeared when the content of 20A was higher than 5 wt%.
