Summary:PURPOSE: Provided is a composition for a fuel hose, which has improved heat resistance, ozone resistance and cold resistance, and reduces the generation of leak and crack. CONSTITUTION: The composition for a fuel hose comprises 100 parts by weight of an epichlorohydrin polymer rubber consisting of an epichlorohydrin copolymer and an epichlorohydrin terpolymer in the weight ratio of 55-65:35-45; 40 to 50 parts by weight of carbon black(FEF) and 13 to 18 parts by weight of an anti-aging agent. The composition is used to produce a fuel hose comprising an inner tube(10), an intermediate rubber layer(20), a scale-shaped fiber layer(30) and an outer layer(40), wherein the intermediate rubber layer(20) and/or the outer layer(40) can be formed of the composition. 본 발명은 연료용 호스 조성물에 관한 것으로서, 보다 상세하게는 저압용 내장편상식 연료용 호스의 중간고무층과 외면층에 사용되는 고무 조성물을 내오존성 및 저온성의 특성을 가지는 단량체로 구성되는 코폴리머(copolymer)와 내열성 및 내구력이 우수한 특성을 가지는 단량체로 구성되는 터폴리머(terpolymer)로 이루어진 에피클로로히드린 폴리머 고무 폴리머를 사용하고, 카본블랙과 노화방지제의 함량을 증가시키므로써 호스를 장기간 사용하였을 경우 문제시 되던 누수현상(leak)과 크랙(crack)의 발생을 감소시키고 내열성, 내오존성, 내한성 등의 물성을 향상시킨 개선된 연료용 호스 조성물에 관한 것이다.
