Abstract
폴리케톤은 일산화탄소, 에틸렌, 프로필렌을 단량체로 중합되는 삼중공중합체 (terpolymer)로서 폴리아미드, 플리에스테르, 폴리카보네이트 등의 일반 엔지니어링 플라스틱 소재에 비해 원료 및 중합 공정비가 저렴한 소재이다. 또한 기계적 특성과 내열성, 내화학성, 연료투과성, 내마모성 등이 우수하여 기존 엔지니어링 플라스틱 소재를 대체할 수 있는 환경 친화적인 소재로 주목을 받고 있다. 본 연구에서는 폴리케톤의 내열성을 향상시키기 위해 탄성체(Ethylene propylene copolymer, Nitrile butadiene rubber, Ethylene acrylic rubber)를 배합하여 블렌드물을 제조하였고, 각 소재에 대하여 내열성, 내유성에 평가에 따른 특성을 분석하였다. Terpolymer polymerized carbon monoxide, ethylene and propylene as monomer, Polyketone is low-cost material compared with general engineering plastics such as polyamide, polyester, polycarbonate. Moreover, it is excellent in mechanical properties, chemical resistance, fuel permeability and abrasion resistance. So, it is attracted attention as the environmental friendly material to replace conventional engineering plastics. In this study, has been prepared Polyketone/Rubber (Ethylene propylene copolymer, Acrylonitrile butadiene rubber, Ethylene acrylic rubber) blends to improve heat resistance and investigated characteristic behavior after heat/oil aging.
