<p>PROBLEM TO BE SOLVED: To provide a laminate rubber hose excellent in terms of biodiesel fuel oil resistance and having a high adhesiveness in-between a fluorinated rubber layer provided as an innermost layer and an NBR layer adjacent thereto.SOLUTION: The innermost layer 3 consists of a fluorinated rubber including (A) a polyol-crosslinkable fluorine-containing elastomer, (B) a polyol crosslinking agent, and (C) calcium hydroxide in a state where no more than 2 pts.wt. of the component (C) is mixed with respect to 100 pts.wt. of the component (A). The inner layer 5 consists of a rubber including (D) an acrylonitrile-butadiene rubber, (E) a metal hydroxide, and (F) at least one selected from among DBU, DBU salts, DBN, DBN salts, and organic phosphonium salts in a state where at least 0.5 pt.wt. and no more than 30 pts.wt. of the component (E) and at least 0.1 pt.wt. and no more than 10 pts.wt. of the component (F) are mixed with respect to 100 pts.wt. of the component (D).</p> |
