Abstract

Sustainable calcium-zinc (Ca-Zn)-based complex stabilizers were developed to replace existing heavy metal-based polyvinyl chloride (PVC) stabilizers, such as cadmium, barium, and lead, which are known for their toxicity to the human body. A series of PVC composites were prepared by adopting MgAl-layered double hydroxide (MgAl-LDH) as a co-stabilizer, and their thermal stability and cytotoxicity were subsequently evaluated. The mixing ratio of the Ca-Zn:Sn:MgAl-LDH complex stabilizer corresponding to the results of the discoloration and cytotoxicity tests using human lung fibroblasts (MRC-5) was derived as 1:0.2:1. Additionally, it was confirmed that the heat resistance of the composite supplemented with 0.2 phr of aluminum acetylacetonate, which has a β-diketone structure, was improved by nearly 2 h.


인체 유해성이 알려진 카드뮴, 바륨, 납 등 기존의 중금속계 폴리염화비닐(PVC) 안정제를 대체할 수 있는 지속 가능한 칼슘-아연(Ca-Zn)계 복합안정제 개발을 수행하였다. MgAl-층상이중수산화물(MgAl-LDH)을 보조 안정제로 채택하여 일련의 PVC 복합체를 제조한 후 열안정성과 세포독성을 평가하였다. 변색 및 인간 폐 섬유아세포(MRC-5)를 이용한 세포독성 시험 결과에 부합되는 Ca-Zn:Sn:MgAl-LDH 복합안정제의 혼합비는 1:0.2:1로 도출되었다. 추가로 β-디케톤 구조의 알루미늄 아세틸아세토네이트가 0.2 phr 첨가된 복합체의 경우 열안정성이 2시간 가까이 향상됨을 확인할 수 있었다.
