Abstract
The invention relates to a hose made of a thermoplastic polymer comprising a core and a cover provided with a reinforcement, in particular in the form of a multilayer reinforcing structure, wherein each core and cover consists of a thermoplastic polymer and wherein, according to the invention, an intermediate coupling layer is incorporated into the core and/or cover material by welding and is connected in the form of a reinforcement. The appropriated variants of the embodiment of the intermediate coupling layer are also enclosed.
Claims22
Hose, comprising a core and a cover having an embedded reinforcement support in the form of a single-layer or multi-layer reinforcement structure, whereby the core and the cover comprise a thermoplastic elastomer, in each instance, wherein an adhesion-imparting intermediate layer comprising an olefin plastic is worked in, bonded to at least one of the core and the cover material, and enters into a bond with the reinforcement support and wherein the reinforcement support is surrounded with twisted yarns of the olefin plastic.
Hose, comprising a core and a cover having an embedded reinforcement support in the form of a single-layer or multi-layer reinforcement structure, whereby the core and the cover comprise a thermoplastic elastomer, in each instance, wherein an adhesion-imparting intermediate layer comprising a thermoplastic elastomer, a hydrocarbon resin, and a functionalized polymer is worked in, bonded to at least one of the core cover material, and enters into a bond with the reinforcement support, wherein the functionalized polymer is a malein anhydride graft polyethylene or malein anhydride graft polypropylene, or an acrylate copolymer functionalized with polar CO groups or epoxy groups.
Hose, comprising a core and a cover having an embedded reinforcement support in the form of a single-layer or multi-layer reinforcement structure, whereby the core and the cover comprise a thermoplastic elastomer, in each instance, wherein an adhesion-imparting intermediate layer comprising a thermoplastic elastomer, a hydrocarbon resin, and a functionalized polymer is worked in, bonded to at least one of the core cover material, and enters into a bond with the reinforcement support, wherein the proportion of the functionalized polymer is 0.5 to 20 wt.-%.
