초록

E-TPE(Engineering Thermoplastic Polyether Ester)는 Ester 관능기를 갖는 Elastomer 소재로서 리사이클이 가능하며 빠른 가공성을 지닌다. 또한 경량성이 뛰어나 자동차의 경우 연비향상에 도움을 주는 친환경 소재로 부각되고 있다. 고무와 엔지니어링 플라스틱의 특성을 모두 가지고 있는 E-TPE는 사용 가능한 온도영역이 넓고, 내열성 및 내유성이 우수하여 자동차 부품소재분나 전기전자분야의 신소재로 주목받고 있으나 국내에서는 원천기술이 부족하여 전량 수입에 의존하고 있는 실정이므로 연구개발이 시급하다. 본 연구에서는 하드 세그먼트로 폴리에스터계(TPEE)를 base로 하여 소프트 세그먼트로 Ethylen-prophylene-Copolymer와 CSM(Choloro sulphonated polyethylene Rubber), VAMAC(Ethylene Acrylic Rubber), NBR(Acrylonitrin Butadiene Rubber)의 탄성체를 1,3-Phenylene-bisoxazoline 가교제로 동적가교 시켜 함량과 첨가된 고무에 따른 물성을 관찰하였다. 그 결과 NBR 첨가된 동적가교물의 물성이 다른 고무에 비해 내열성 및 내유성 향상에 되었음을 확인하였다.

E-TPE (Engineering Thermoplastic Polyether Ester) was Ester Elastomer with functional groups as recycling and fast processability. In addition, if the car's lightweight enough to highlight eco-friendly materials that help to improve fuel economy has become. Have all the attributes of the rubber and engineering plastics E-TPE the available temperature area is spacious, heat resistance and oil resistance is excellent but getting attention as a new material in the field of auto parts in the field of electrical and electronic domestic depends entirely on imports by the lack of core technology and has been research and development is urgently needed. In this study, the hard segments, polyester (TPEE) as the base soft elastomers of the segments Ethylen-prophylene-Copolymer and CSM (Choloro sulphonated polyethylene Rubber), VAMAC (Ethylene Acrylic Rubber), NBR (Acrylonitrin Butadiene Rubber), 1, 3-Phenylene-bisoxazoline is dealing with Dynamic Vulcanized by content and added rubber properties, thermal variation observed. As a result, the properties of the dynamic vulcanization with NBR compared to other rubber heat resistance and oil resistance is on the increase.
