Definitions

  • the invention relates to a plate-shaped component consisting of a core layer made of foamed plastic and plastic outer layers attached to the core layer on both sides, wherein flat stiffening layers are arranged between the core layer and the plastic outer layers.
  • the invention further relates to a method for producing this plate-shaped component.
  • stiffening layers are glued to the entire surface of the core layer or the adjacent outer layers. This bonding can be carried out relatively easily during the continuous manufacture of the plate-shaped component, for example by applying an adhesive layer to the metal sheets on both sides. Under operating conditions in which the plate-shaped element is exposed to high shear forces and / or thermal stresses, a high level of bond strength is required, which cannot be easily achieved with an adhesive bond.
  • the object of the invention is to provide a plate-shaped component which is distinguished from known components by increased bond strength, and at the same time can be produced in a simple and rational manner.
  • a plate-shaped component of the type mentioned at the outset is proposed, which is characterized in that the stiffening layers are perforated and are bonded to both the core layer and the outer layers without adhesive.
  • thermoplastic materials used in the core layer and the outer layers are thermoplastics that can be welded together.
  • Polyolefins, for example, are advantageously used as thermoplastic materials
  • PE Polyethylene
  • PP polypropylene
  • PA polyamides
  • PS polystyrene
  • ABS Acrylonitrile-butadiene-styrene polymer
  • ASA acrylic ester-styrene-acrylonitrile polymer
  • SAN styrene-acrylonitrile copoly er
  • thermoplastic polyesters for example polyethylene terephthalate
  • PETP polyethylene terephthalate
  • PBTP polybutylene terephthalate
  • Metal sheets which preferably consist of steel, aluminum or a metal alloy, are advantageously used as perforated stiffening layers between the core and outer layers in the plate-shaped component according to the invention.
  • perforation in the stiffening layers consists in the fact that they are hole-like or slit-shaped, preferred embodiments for these perforated reinforcement layers being those in the form of grids or sieves. Furthermore, it is also possible to use woven or fiber composites, for example fiber-reinforced panels, as perforated stiffening layers between the core and outer layers, these being inorganic or organic in nature.
  • the invention furthermore relates to a method for producing a plate-shaped component of the type mentioned at the outset, which is characterized in that stiffening layers which are perforated on both sides and which are subsequently prepared in further extruder units are applied to the melted plastic melt of the core layer in an extruder Plastic melts of the outer layers are applied, and that a connection between the respective layers is formed by subsequent pressing.
  • thermoplastics that can be welded to one another are preferably used as materials for the core and outer layers.
  • Particularly suitable thermoplastic materials are polyolefins, for example polyethylene (PE) or polypropylene (PP), and / or polyamides (PA) and / or polystyrene (PS) and / or styrene polymers, for example acrylonitrile-butadiene-styrene polymer (ABS), acrylic ester-styrene-acrylonitrile polymer (ASA) or styrene-acrylonitrile copolymer (SAN), and thermoplastic polyester, for example polyethylene terephthalate (PETP) or polybutylene terephthalate (PBTP).
  • PE polyethylene
  • PP polypropylene
  • PA polyamides
  • PS polystyrene
  • ABS acrylonitrile-butadiene-styrene polymer
  • ASA acrylic ester-styrene-acrylonitrile polymer
  • Metal sheets namely made of steel, aluminum or metal alloys, are also preferably used as perforated stiffening layers.
  • Hole-like or slit-like stiffening layers preferably in the form of a grid or sieve, can in particular be used as perforated stiffening layers.
  • perforated stiffening layers in the form of fabrics or fiber composites, for example made of fiber-reinforced panels, the materials used therein being inorganic or organic in nature.
  • FIG. 1 shows a section through a component and FIG. 2 shows a component with the outer layer partially removed.
  • the plate-shaped component 1 shows the plate-shaped component 1 according to the invention, consisting of the core layer 2 made of foamed plastic, to which the outer layers 3 - also made of plastic - are connected on both sides. Perforated stiffening layers 4 are provided between the core layer 2 and the outer layers 3. The connection between the outer layers 3 and the core layer 2 takes place by welding the plastic of the core layer 2 to the plastic of the outer layers 3 in the area of the weld joints 5.
  • the plate-shaped component 1 according to the invention can be produced as a calender in a system known per se, consisting of extruders and a downstream double belt press.
  • the plastic melt for the core layer which can additionally contain blowing agents for foaming, is provided in an extruder unit.
  • This plastic melt can be produced, for example, from granular polypropylene.
  • the perforated stiffening layers 4, which preferably have a thickness of 0.1-1.0 mm, are attached to these on both sides, which brings about a significant increase in the rigidity of the component. For example, approximately 0.5 mm thick, perforated aluminum foils can be used as stiffening layers 4.
  • the plastic melts for the outer layers 3 are subsequently applied to these perforated aluminum foils serving as stiffening layers 4.
  • these can consist of polypropylene and are obtained from the corresponding plastic starting material in separate extruder units.
  • both the melt of the outer layers 3 and the melt of the core layer 2 can penetrate through the perforation, so that a kind of "melt bond" is formed.
  • the composite adhesion which is advantageous for the plate-shaped component 1 is produced by pressing this “melt composite” in a downstream double belt press, so that the layers weld to one another in the area of the weld joints 5. Furthermore, the plate-shaped component 1 is calibrated accordingly by the contact pressure applied in the double belt press. It is then cooled and can be processed, for example, by sawing.
  • the plate-shaped component 1 according to the invention is extremely dimensionally stable and can be further processed in a simple manner, for example by milling, nailing or sawing. Furthermore, the plate-shaped component according to the invention is weather-resistant, so that it can be used not only indoors but also outdoors. A particularly preferred application is in the outdoor area for boarding or cladding buildings.
