A flexible hose (1) according to the invention comprising an under-hose (2), a metal layer, a barrier layer (4), an armouring layer (6, 7) and an outer cover layer (8), is particularly suitable for the transport of media which must be held completely isolated from the surroundings out of regard for the media as well as the environment. For this purpose, it is demanded that the metal layer (4) is tight and is included as an integrated layer in the hose laminate. Therefore, the metal layer (4) must adhere to the under-hose (2), and the subsequent armouring layer (6, 7) must adhere to the foil layer (4) in order for the influences of forces to be distributed, i.e. absorbed by the whole of the hose laminate. According to the invention, this can be effected by a modification of the plastic surface (2) by a plasma/corona treatment, after which a layer of polymer (3) which can be vulcanised is applied under the metal layer (4), the surface of said metal layer (4) then being provided with a layer of vulcanisable polymer (5). Hereafter, the layers are heated and a vulcanisation is carried out, which effectively binds the layers together. There is hereby achieved a hose laminate whereby the influence of forces is distributed to the whole of the laminate, whereby the metal layer (4) is spared so that it does not suffer damage. The hose is particularly suitable for the transport of coolants and other volatile media. |
