- both cover sheets 2.1, 2.2 have substantially the same thickness, for example approximately 0.3 mm, and have the same material quality. But it can also cover plates 2.1, 2.2 different thickness and / or material quality for Production of the composite material 2 can be used.
- the wall element according to the invention serves as a facade cladding element, the cover sheets 2.1, 2.2 can be provided with different corrosion protection layers.
- Facing the solar side facing element be provided with an aluminum-based coating, which has a high heat reflectivity.
- the core layer 2.3 consists of a fibrous, to at least 600 ° C, preferably to at least 700 ° C temperature-resistant sealing material having a thickness of about 0.5 to 2.0 mm, preferably about 0.6 to 1.5 mm, and more preferably in the range of about 0.7 to 1.3 mm.
- the material of the core layer 2.3 consists of a mixture of inorganic fibers, preferably mineral fibers, and inorganic filler, preferably mineral fillers, with a small proportion of organic fibers and
- the inorganic fibers, which together with the inorganic filler constitute the main constituent of the core layer material, are preferably bio-soluble mineral fibers.
- the core layer material may contain a mineral, halogen-free fire retardant, which has a high flue gas suppression effect. Since the proportion of organic fibers and organic binder in the core layer 2.3 is very low, results in a fire or heat exposure only a low flue gas development.
- the inorganic fibers and mineral fillers of the core layer 2.3 enable such a sealing material layer to withstand continuous use temperatures up to 900 ° C or even up to 1000 ° C, preferably non-flammable.
- the core layer 2.3 designed in this way provides good thermal insulation and good soundproofing.
- the fiber-containing core layer 2.3 gives the sandwich-type wall element 1, 1 'according to the invention, in addition to the high temperature resistance, at the same time good Thermal insulation also significantly higher stiffness properties compared to a core layer of plastic with finely dispersed inorganic additives, such as those made of metal-plastic-metal composite material
- Composite plate according to DE 25 08 353 AI has. These higher stiffness properties make it possible to use relatively thin metallic cover layers 2.1, 2.2 and thus to reduce the weight of the sandwich-type wall element 1,.
- each of the cover plates 2.1, 2.2 of the composite material 2 is formed considerably thinner than the core layer 2.3.
- the thickness of the core layer 2.3 is at least 1.5 times, preferably at least 2 times, and more preferably at least 2.5 times, the thickness of the thinnest of the two cover plates 2.1, 2.2.
- the cover plates 2.1, 2.2 are connected by gluing to the core layer.
- the adhesive is preferably an aqueous-based adhesive, for example
- Polyurethane dispersion adhesive For a sufficient connection of cover plate 2.1, 2.2 and core layer 2.3 of the adhesive, for example, with a layer thickness between 5 to 25 ⁇ , preferably between 8 to 15 ⁇ applied to the cover plate 2.1, 2.2.
- the application of the adhesive can be done for example by spraying, doctoring or by application rollers.
- the connection of cover plates 2.1, 2.2 and core layer 2.3 is then preferably carried out by means of a heated
- Double belt press (not shown), in which the adhesive is activated by pressure and temperature and crosslinked with the fibrous, temperature-resistant core layer 2.3.
- the core layer 2.3 is encapsulated in the composite material 2 by the adhesive and / or the cover plates 2.1, 2.2 against the ingress of moisture.
- the composite material 2 according to the invention can be readily plastically deformed, in particular by folding and / or embossing. For this purpose, for example, cut from a corresponding strip-shaped composite material 2 boards and in a molding press (not shown) to a wall element 1, formed.
- Wall element (wall cladding element) 1 according to the invention, which make use of the invention specified in the appended claims even in embodiments which deviate from the illustrated embodiment.
