Plate-shaped body for wall cladding or the like and method for its production

The invention relates to a plate-shaped body with relief-like visible side Jür wall cladding od. Like., And a method for producing such a plate-shaped body.

For cladding walls or the like, for example, plate-shaped bodies are used - in the following, plates for short called - used to give the wall a pleasing appearance. The familiar, very decorative acting metal plates have the disadvantage that they are relatively high in terms of cost and weight. the end for this reason one has already gone over to and plastic panels that are far cheaper in terms of weight to be treated in such a way that their visible sides act like metal plates. To achieve this it is known to subject the surfaces of the plates to a galvanic treatment or to cover them with metal foils. As has been shown, panels treated in this way are capable

not to withstand the normal requirements, as they are relatively sensitive to shock and friction. This also applies to the same extent to plastic sheets that are coated or sprayed with metallic surfaces are provided.

The invention is based on the object of a plate-shaped Body with metallic surface effect too k create where the disadvantages that the conventional

Adhering to plates, .avoided.

Starting from a plate-shaped body of the initially mentioned type, the object of the invention is achieved in that it is essentially made of plastic and a surface layer enriched with metallic components, preferably in powdered form having. The components can consist of iron, non-ferrous or precious metals.

The invention also relates to a method for producing such a body. According to the invention, the procedure is that a powdered metal is mixed into a liquid, cold-curable plastic mass and this mixture is then poured into a mold equipped with any embossing on the bottom surface, and that after the casting has hardened, the specific heavier. Metal parts heavily enriched with metal surface,

subjected to a polishing process that exposes the metal will. By means of these measures according to the invention, a created plate-shaped body, the metallic surface effect is retained even with the highest requirements, which is due to the fact that the Metal layer forms a homogeneous bond with the plastic. '

As tests have shown, is the novel plate also absolutely weatherproof. It has been exposed to temperatures from minus 40 ° to plus 100 ° C without being exposed to To have suffered damage from these extreme temperatures. The metallic one or the one heavily interspersed with metal Top of the plate can be done with wire brush, steel wool or other polishing agents without impairing the quality of the panel leads »On the contrary, the desired effect (blank or matt) can be increased depending on the type of polish.

The plate according to the invention is also characterized by a relatively low weight. Depending on your taste and determination, casts of stone structures, Produce machined metal plates, reliefs, etc., which, due to the casting process, are deceptively similar to the respective original. Plates with for example Stone structures and pewter or bronze surfaces are ideal for indoor and / or external facings. After all, they also provide significant economic advantages, since

their use does not take into account any static problems Need to ground, no masonry required and they are priced very cheaply. With commercially available adhesives you can effortlessly - also from unskilled labor - to be relocated.

The strength of the metal-plastic composite layer leaves determine oneself, d. H. that depending on the quality and requirements, more or less metal powder in the still liquid plastic compound is entered.

In a further embodiment of the invention it can be provided that to stabilize the casting the composite casting is made of cold-curable plastic. The pr-ei-felich much higher lying, Casting layer containing powdered metal can thus be made relatively thin, as by the Infusion of cheaper plastic the desired stability can be achieved.
