Composite for tight connection of components or building elements, comprises has two joining parts, adhesive layer arranged between the joining areas of the joining parts, and a protective layer resistant against the medium

摘要

The composite comprises two joining parts (11, 12), an adhesive layer (13) arranged between the joining areas (111, 121) of the joining parts, and a protective layer (16), which is resistant against the medium. The external surface (14) of the composite is exposed to fluid or gaseous medium. The support layer covers the surface portion of the adhesive layer on the external area of the composite exposing the medium. The protective layer covers areas of the joining surfaces directly adjacent to the adhesive layer on the external surface of the composite exposing the medium. The composite comprises two joining parts (11, 12), an adhesive layer (13) arranged between the joining areas (111, 121) of the joining parts, and a protective layer (16), which is resistant against the medium. The external surface (14) of the composite is exposed to fluid or gaseous medium. The support layer covers the surface portion of the adhesive layer on the external area of the composite exposing the medium. The protective layer covers areas of the joining surfaces directly adjacent to the adhesive layer on the external surface of the composite exposing the medium. The protective layer exists out of peroxidic cross-linked fluoro-elastomers, hydrogenated nitrile-rubber and aliphatic polyurethane. The protective layer is applied directly on the composite external area treated with bonding agent. The thickness of the protective layer is less than 100 mu m. The joining part consists of metallic and/or non-metallic materials and the joining parts are components of fuel injection valve.
