Summary:PURPOSE: Provided is a rubber composition for a fuel hose, which is excellent in heat resistance, ozone resistance, and pressure resistance and reduces heat curing of the hose, leakage, and the generation of crack. CONSTITUTION: The rubber composition for the fuel hose comprises 100pts.wt. of an epichlorohydrin blend comprising an epichlorohydrin homopolymer and an epichlorohydrin terpolymer in the weight ratio of 80:20-50:50, 40-50pts.wt. of a carbon black, and 13-18pts.wt. of an anti-aging agent, wherein the epichlorohydrin terpolymer has a monomer selected from the group consisting of a saturated epoxy, an unsaturated epoxy, or a mixture thereof. 본 발명은 호스용 고무 조성물에 관한 것으로서, 보다 상세하게는 자동차 또는 산업용 내열 호스 등 내열성 및 내압성이 요구되는 호스용 고무 조성물에 있어서, 에피클로로히드린 단일중합체; 포화 에폭시, 불포화 에폭시 및 이들의 혼합물로 구성된 그룹으로부터 선택된 단량체를 가진 에피클로로히드린 삼원공중합체로 이루어진 에피클로로히드린 블렌드에 카본 블랙 및 노화방지제가 특정 함량으로 함유되어 있는 조성물에 관한 것으로, 상기 얻어진 조성물은 내열성, 내오존성 및 내압성이 우수하여 종래 자동차 및 산업용 호스에서 발생하던 호스의 열경화, 누수현상(leak)과 크랙(crack)의 발생을 감소시킨다.
