The present invention relates to a polyketone used in a motor fuel tube, and more specifically, to a motor fuel tube comprising ethylene-perfluoroethylenepropylene as a first layer, and a blend comprising a linear alternating polyketone formed by carbon monoxide and at least one type of ethylene-based unsaturated hydrocarbon and a sulfur amide-based plasticizer as a second layer. The motor fuel tube of the present invention, by overcoming the drawback of a conventional EvOH having low adhesive strength, does not require adhesive layers and can be reduced in thickness while having excellent gas barrier properties, airtightness, and impact resistance.

    본 발명은 자동차용 연료 튜브에 쓰이는 폴리케톤에 관한 것으로, 특히 에틸렌-퍼플루오로에틸렌프로필렌을 제1층; 일산화탄소와 적어도 1종의 에틸렌계 불포화 탄화수소로 이루어진 선상 교대 폴리케톤 및 설퍼아마이드계 가소제를 포함하는 블렌드를 제2층; 으로 가지는 자동차 연료 튜브에 관한 것이다. 본 발명의 자동차용 연료 튜브는 종래의 EvOH의 접착력이 낮다는 단점을 극복할 수 있어 접착층이 필요하지 않아 연료 튜브의 두께를 줄일 수 있으면서도 우수한 가스차단성, 기밀성 및 내충격성을 가진다.
