초록

폐폴리(염화 비닐)수지 [waste poly(vinyl chloride), RPVC]와 폐폴리에틸렌 수지 (waste polyethylene, RPE)의 용융 블렌드에 대한 연구로 상용성 향상을 위해 비닐 아세테이트 함량이 다른 4 종류의 에틸렌 비닐 아세테이트 공중합체 (EVA)와 에틸렌 메타크릴산 나트륨염 공중합체 (이오노머)를 상용화제로 사용하였으며, 혼합 순서 및 횟수를 변화시키며 물성의 변화를 조사하였다. 비닐 아세테이트의 함량이 높은 EVA가 상용화제로 첨가되었을 경우, 소량 첨가시 큰 인장 강도의 변화를 확인할 수 있었으며, 이러한 결과는 형태학적 특성 변화를 관찰하여 확인할 수 있었다. 블렌드에서의 상용화제의 종류에 따른 상용성은 적외선 분광기를 사용하여 관찰하였으며, 기계적 물성 분석을 통해 EVA 첨가시 이에 따른 인장 강도의 증가를 확인할 수 있었다. 또한, 혼합 순서 및 횟수 변화에 따른 물성의 변화를 확인하였다.

The polymer blends of waste poly(vinyl chloride) (RPVC) and waste polyethylene (RPE) were prepared by melt mixing. Various ethylene-vinyl acetate copolymers (EVA) and ethylene-methacrylic acid Na salt copolymer (ionomer) were used as compatibilizer. Their morphologies and mechanical properties were evaluated as a funtion of mixing sequence and time. EVA with high vinyl acetate contents showed a rapid increment of tensile properties when small amount was added. Tensile properties of the blends were gradually increased with the addition of ionomer. Morphologies of RPVC/RPE blends were analyzed by scanning electron microscopy. FT-IR data showed that EVA was a good compatibilizer in RPVC/RPE blend compared to ionomer. Mechanical properties of the blends were highly enhanced when RPVC and compatibilizer were mixed and first RPE was added later.
