Description

Verfahren zur Herstellung von Bauelementen aus mit Kunststoff beschichteten Schaumstoffen Zusatz zur Anmeldung: Sch 25128 X /39 a3 -Auslegeschrift 1172 419 Gegenstand der Patentanmeldung Sch 25128 39 aus ist ein Verfahren zur Herstellung von einseitig mit Epoxyharzen beschichteten, nachträglich verformbaren Bauelementen aus Polystyrolschaumstoffen, dadurch gekennzeichnet, daß auf Polystyrolschaumstoffe Epoxyharzschichten, die als Härter ein oder mehrere Amine, insbesondere ein oder mehrere Polyaminoamide auf Basis di- oder polymerisierter Fettsäuren enthalten, und Faserschichten aufgebracht und die Epoxyharzschichten ausgehärtet werden.Process for the production of components from plastic-coated Foam additive for registration: Sch 25128 X / 39 a3 -Auslegeschrift 1172 419 The subject of patent application Sch 25128 39 from is a method for production of subsequently deformable components coated on one side with epoxy resins made of polystyrene foams, characterized in that on polystyrene foams Epoxy resin layers which, as hardeners, contain one or more amines, in particular one or more contain several polyaminoamides based on di- or polymerized fatty acids, and fiber layers are applied and the epoxy resin layers are cured.

Eine vorteilhafte Weiterentwicklung des Verfahrens nach Patentanmeldung Sch25128X/39a3 besteht darin, daß man das einseitig beschichtete und in gewünschter Weise verformbare Bauelement auf der unbeschichteten Seite zweckmäßig unter Verwendung einer Verstärkung, z. B. mittels Gewebe oder Glasfaser, mit Kunststoff beschichtet und dann die zweite Kunststoffschicht aushärten läßt. An advantageous further development of the process according to the patent application Sch25128X / 39a3 consists in the fact that one side is coated and in the desired Way deformable component on the uncoated side expediently using a reinforcement, e.g. B. by means of fabric or fiberglass, coated with plastic and then cure the second plastic layer.

Eine besonders günstige Ausführungsform des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, daß man die Kunststoffbeschichtung mit Epoxyharzen vornimmt, welche mit Polyaminoamiden auf Basis di- oder polymerisierter Fettsäuren gehärtet werden. A particularly favorable embodiment of the method according to the invention is characterized in that the plastic is coated with epoxy resins, which are hardened with polyaminoamides based on di- or polymerized fatty acids will.

Diese neuen Bauelemente ermöglichen die Herstellung verschieden geformter Bauteile, indem man die einseitig beschichteten Schaumstoffplatten bzw. daraus hergestellte Schnittmuster durch Biegen in die gewünschte Form bringt, danach auch die unbeschichtete Seite zweckmäßig unter Verwendung einer Verstärkung, z. B. mittels Glasfasern, beschichtet und dann die zweite Kunststoffbeschichtung aushärten läßt. Das so verformte Bauteil ist danach völlig steif und geht nicht mehr in seine alte Lage zurück. These new components enable the production of differently shaped Components by making the foam panels coated on one side or made from them Bend the pattern into the desired shape, then also the uncoated one Side expediently using a reinforcement, e.g. B. by means of glass fibers coated and then allowing the second plastic coating to cure. The component deformed in this way is then completely stiff and does not return to its old position.

Als Schaumstoffe können z. B. außer solchen aus Polystyrol auch solche aus Polyvinylchlorid, Polyurethan, Hartgummi, Harnstoffharz oder Siliconharz Verwendung finden. Für die Kunststoffbeschichtung ist Epoxyharz, welches mit einem Amin, insbesondere einem Polyaminoamid auf Basis di- oder polymerisierter Fettsäure verwendbar, jedoch können auch Polyesterharze, Phenol-, Melamin-, Furan-und Siliconharze zum Einsatz kommen. Es muß nur auf Verträglichkeit zwischen Schaumstoff und Kunststoffbeschichtung geachtet werden. Der Vorteil dieser erfindungsgemäß hergestellten Bauelemente bzw. in dem Verfahren zu ihrer Herstellung liegt in der großen Einfachheit, mit der geformte Bauteile erhalten werden können, sowie in der Festigkeit bei gleichzeitig geringem Gewicht. As foams, for. B. in addition to those made of polystyrene also those made of polyvinyl chloride, polyurethane, hard rubber, urea resin or silicone resin Find. For the plastic coating is epoxy resin, which with an amine, in particular a polyaminoamide based on di- or polymerized fatty acid can be used, however Polyester resins, phenolic, melamine, furan and silicone resins can also be used come. It just has to be based on compatibility between foam and plastic coating be respected. The advantage of these components manufactured according to the invention or in the process of their manufacture lies in the great simplicity with which they are molded Components can be obtained, as well as in strength at the same time low Weight.

Diese Bauelemente bzw. das Verfahren zu ihrer Herstellung haben sich besonders im Bootsbau bewährt, können jedoch auch auf anderen Gebieten, z. B. im Bauwesen, Maschinen- und Karosseriebau, Flugzeug- und Raketenbau, für die Herstellung von geformten Leichtbauelementen, für Nissenhütten, Tanks, Kühlschränke und Möbel zur Anwendung kommen. These components and the process for their production have become Tried and tested especially in boat building, but can also be used in other areas, e.g. B. in Construction, machine and body construction, aircraft and rocket construction, for manufacture of molded lightweight construction elements, for Nissen huts, tanks, refrigerators and furniture come into use.
