Definitions

• the invention relates to composite components made of a core layer A made of polystyrene particle foam and at least one cover layer C made of cement mortar and a method for producing the composite components.
• the invention was therefore based on the object of providing composite components which do not have these disadvantages.
• the cement mortar is preferably first poured into the mold, then the foam particles are added and the mold is closed.
• the particles expand as a result of the evaporation of the propellant still contained in them.
• these expanding particles exert pressure on the mortar layer.
• the liquid cement evades this pressure by partially penetrating the gusset of the foam particles, so that there is a smooth transition between layers A and C.
• the foam particles sinter and the cement mortar sets.
• the method according to the invention enables considerable time and cost savings in production without the use of adhesives.
• the drawing shows a section through the composite component according to the invention: (1) denotes a cover layer C, (2) the core layer A and (3) the intermediate layer B.
• On the intermediate layer one can see the considerable penetration of the pre-expanded particles (4) with the cement mortar (5), which has penetrated into the gaps between the foam particles, at a time when the two materials were not yet sintered or solidified.
• the cement mortar (5) remains in the interlayer in the gusset volume and hardens there. This setting and sintering of materials that have penetrated into one another causes the intermediate layer to be strongly consolidated and the core layer to bond well to the cover layer or the cover layers without the use of adhesives.
• the thickness of the composite components according to the invention can vary within wide limits, preferably between 20 and 250 cm, the cover layer C is preferably between 1 and 20 mm thick.
• the composite components can have different shapes; e.g. they can be designed as flat sheets, as corrugated sheets or as roof tiles.
• the plate-shaped components can be easily, e.g. can be divided or cut by cutting discs or saws to enable easy installation.
• the polystyrene foam particles can contain the usual additives, e.g. Flame retardants or pigments, the cement mortar can also contain the usual additives in order to give the composite components the desired properties.
• the usual additives e.g. Flame retardants or pigments
• the cement mortar can also contain the usual additives in order to give the composite components the desired properties.
