It is particularly preferable to use ultrahigh molecular weight polyethylene having a viscosity average molecular weight of 1,000,000 or more because foaming can be prevented in the vulcanization process.
- the layer thickness of the resin layer 9 is, for example, about 0.1 mm to 0.5 mm. If the layer thickness is less than 0.1 mm, sufficient durability or the like is difficult to obtain, and if it exceeds 0.5 mm, the hose flexibility tends to be adversely affected.
- the inner rubber layer 3 is selected from materials excellent in adhesiveness with the resin layer 9, and for example, a rubber composition made of natural rubber and SBR (styrene butadiene rubber) is used. If this rubber composition is used, it can be firmly melt bonded to the resin layer 9 made of ultrahigh molecular weight polyethylene. In this rubber composition, the weight ratio of natural rubber is preferably 50% or more.
- the inner rubber layer 3 is a material that is not directly in contact with the fluid transported by the marine hose 1 but has excellent erosion resistance against the fluid in consideration of the case where the resin layer 9 is damaged in an unexpected situation. It is preferable to make it. Since the rubber composition comprising natural rubber and SBR has excellent erosion resistance against various fluids, the rubber composition obtained by blending the inner rubber layer 3 with natural rubber and SBR also from this viewpoint.

- the resin film 9 protruded from one end side of the connecting metal fitting 2 is folded back to the connecting end surface of the flange portion 2a and pasted through the adhesive layer 10.
- connection fitting 2 is extrapolated to the mandrel 11 and set at a predetermined position.

- another resin film 9 is disposed on the outer peripheral side of the mandrel 11 so as to overlap with the resin film 9 protruding from the other end side of the connecting metal fitting 2.
- the overlap margin between the resin films 9 is, for example, about 10 mm to 100 mm.
- the resin film 9 is wound around the outer peripheral surface of the mandrel 11 for a required length in the longitudinal direction.
- a member to be the inner rubber layer 3 is laminated on the outer peripheral side of the mandrel 11.

- the resin film 9 is melted and the joint of the resin film 9 is lost, and a single resin layer 9 is formed. Further, the resin layer 9 and the inner rubber layer 3 are firmly melt bonded. In this manner, the resin film 9 is formed to cover the inner rubber layer 3 and the inner peripheral side of the nipple portion 2b with the resin film 9, and the resin layer 9 is extended to the connecting end surface of the flange portion 2a.
- the resin film 9 extended on the connection end surface of the flange portion 2a can be pressed against the connection end surface by a pressing die. Therefore, by vulcanizing the molded body 1A in such a pressed state, the resin film 9 (resin layer 9) can be bonded very firmly to the connection end surface of the flange portion 2a via the adhesive layer 10. . Therefore, it is extremely effective for preventing the resin layer 9 from peeling off.
- the inner rubber layer 3 and the entire area on the inner peripheral side of the nipple portion 2b are covered with the resin layer 9, so that the fluid transported by the marine hose 1 can contact the inner rubber layer 3. Absent. Therefore, even if the fluid is a chemical such as methanol or ethanol, components contained in the inner rubber layer 3 can be prevented from eluting into the fluid. Of course, the components contained in the resin layer 9 do not elute into the fluid.

- a connection member 2 e such as a bolt inserted into the bolt hole 2 d
- the opposing resin layers 9 are pressed against each other. Is done. Therefore, the resin layer 9 is not peeled off at the connection end face of the connection fitting 2, and the resin layers 9 are connected in a watertight manner. Therefore, the fluid can be prevented from coming into contact with the inner rubber layer 3 even at the connecting portion of the marine hose 1, and the components contained in the inner rubber layer 3 can be more reliably prevented from eluting into the fluid. Therefore, it is possible to more reliably prevent the fluid quality from being deteriorated.
- the resin layer 9 extended to the connection end face of the flange portion 2a also functions as a seal member (gasket) that seals the connection end face of the coupling fitting 2 in a watertight manner. Therefore, it is not necessary to provide a separate seal member.
- the radial width W of the resin layer 9 at the connecting end surface of the flange portion 2a is set to 20 mm or more.
- the radial width W of the resin layer 9 at the connection end face of the flange portion 2a is preferably 20 mm or more and 80 mm or less as described above.
- the structure of the marine hose 1 differs in the number of members (reinforcing layers) to be laminated and the types of members to be laminated depending on the required specifications. Therefore, the present invention is not limited to the structure exemplified in the embodiment, but can be applied to the marine hose 1 having various structures. Further, the present invention can be applied to both types of submarine hoses and floating hoses.
