Abstract

Poly(vinyl chloride)(PVC) is one of the world's most widely used plastic resins, and phthalate-based plasti-cizers such as di(2-ethylhexyl)phthalate (DEHP) are often used for manufacturing products. However, recent research results have shown that phthalate plasticizers are harmful both to human body and environments, and environmentally friendly plasticizers (diisononylcyclohexane-1,2-dicarboxylate (DINCH) from BASF & eco-diethyl hexyl cyclohexane (DEHCH) from Hanwha) that could resolve these problems have led to the world’s attention. In this study, the plasticizer was synthesized by reacting 2-ethylhexanoic acid with 3-component 1,4-cyclohexanedimethanol pitch containing cyclohexane structure. PVC specimens were fabricated by applying the synthesized 3-component plasticizer to PVC, and the resulting mechanical properties, migration properties, and thermal properties of the specimens were analyzed in detail.


Poly(vinyl chloride)(PVC)는 전 세계에서 널리 사용되는 범용 플라스틱 수지의 하나로 일반적으로 성형품을 제작할 때는 di(2-ethylhexyl)phthalate(DEHP) 등과 같은 프탈레이트계 가소제가 반드시 필요하다. 하지만 최근 프탈레이트계 가소제가 인체 및 환경에 유해하다는 연구 결과가 나오면서 이러한 문제를 개선하는 (독)BASF사의 diisononylcyclohexane-1,2-dicarboxylate(DINCH) 및 (한)한화케미칼의 eco-diethyl hexyl cyclohexane(DEHCH)와 같은 시클로헥산 기반의 친환경 가소제가 출시되었다. 본 연구에서는 시클로헥산 구조를 함유한 3성분 cyclohexanedimethanol pitch를 원료로 하여 2-ethylhexanoic acid와 반응시켜 3성분 혼합물 형태의 가소제를 합성하였다. 합성된 가소제 혼합물을 PVC에 적용하여 다양한 PVC 시편을 제작하였으며 각 시편의 기계적 특성, 이행 특성 및 열적 특성을 분석하여 PVC용 가소제로서의 효과를 확인하였다.
