The present invention relates to a polyketone used in fuel tubes for an automobile. In particular, the present invention relates to an automobile fuel tube comprising: ethylene-perfluoroethylene propylene as a first layer; a linear alternating polyketone copolymer comprising carbon monoxide and at least one ethylenically unsaturated hydrocarbon as a second layer; and polyamide as a third layer. The fuel tube for an automobile of the present invention can overcome a disadvantage of low adhesiveness of a conventional EvOH, so that thickness of the fuel tube can be reduced since the tube does not require an adhesive layer, and has 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 공중합체를 제2층; 폴리아미드를 제3층; 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.
