초록
TiO2 나노입자가 가소화된 poly(vinyl chloride) (PVC)의 기계적, 열적 특성에 미치는 영향을 연구하였다. 가소화된 PVC는 시간이 지남에 따라 가소제가 용출되면서 기계적 물성의 저하를 야기한다. 이러한 기계적 물성의 저하을 개선하기 위해서 PVC의 물성 및 가소제의 용출 억제를 증진시키고자 PVC/TiO2 복합재료를 제조하였다. 가소제는 di(octcyl phthalate), di(octyl terephthalate)와 di(octyl maleate)를 사용하여 PVC/TiO2 복합재료를 이축압출기를 이용하여 제조하였다. 복합재료의 기계적 특성, 열적 특성을 분석하였으며, 가소제의 용출성과 이행성은 XPS, ASTM 방법을 사용하여 측정하였다.
The effects of TiO2 nanoparticles on the properties of plasticized poly(vinyl chloride) (PVC) were studied. Plasticized PVC causes a deterioration of mechanical properties and plasticizer migration over time. To solve this problem, PVC/TiO2 composites were fabricated for improving its properties and preventing plasticizer migration. PVC/TiO2 composite samples using di(octcyl phthalate), di(octyl terephthalate) and di(octyl maleate) were prepared by twin-screw extruder. Mechanical and thermal properties of composites were analyzed. Migration and exudation behavior of the plasticizer was measured using the ASTM method and X-ray photoelectron spectroscopy (XPS).
