Description
Verfahren zur Herstellung von einseitig mit Epoxyharzen beschichteten, nachträglich verformbaren Bauelementen aus Polystyrolschaumstoffen Es besteht seit langem der Bedarf, billige Bauelemente geringen Gewichts herzustellen. Für diesen Einsatz bieten sich Schaumstoffe auf Polystyrolbasis wegen ihres geringen Gewichts, wegen ihrer sehr guten Schall- und Wärmedämmung und wegen ihrer Feuchtigkeits- und Bakterienunempfindlichkeit mit besonderem Vorteil an. Diese Schaumstoffe sind z. B. in Form von Platten für sich allein wegen ihrer geringen mechanischen Festigkeit als Bauelemente zumeist nicht brauchbar und bedürfen der Verstärkung. Eine derartige Verstärkung gelingt jedoch nicht durch Aufbringen von glasfaserverstärkten, ungesättigten Polyesterharzen, da diese sich als unverträglich mit dem Polystyrol erwiesen haben.Process for the production of one-sided coated with epoxy resins, subsequently deformable components made of polystyrene foams It has existed since there has long been a need to produce inexpensive, lightweight components. For this Polystyrene-based foams are used because of their low weight, because of their very good sound and heat insulation and because of their moisture and Bacteria insensitivity with a particular advantage. These foams are z. B. in the form of plates by themselves because of their low mechanical strength mostly not usable as components and require reinforcement. Such a one However, reinforcement cannot be achieved by applying glass fiber-reinforced, unsaturated ones Polyester resins, as these have proven to be incompatible with the polystyrene.
Es wurde nun ein Verfahren zur Herstellung von einseitig mit Epoxyharzen beschichteten, nachträglich verformbaren Bauelementen aus Polystyrolschaumstoffen gefunden, das dadurch gekennzeichnet ist, 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.There has now been a method of making single sided with epoxy resins coated, subsequently deformable components made of polystyrene foams found, which is characterized in that epoxy resin layers on polystyrene foams, one or more amines, in particular one or more polyaminoamides, as hardeners contain based on di- or polymerized fatty acids, and applied fiber layers and curing the epoxy resin layers.
Die Einsatzfähigkeit von Epoxyharzen auf Polystyrol beschränkt sich auf Härtungstemperaturen des Harzes unterhalb von 60° C. Oberhalb dieser Temperatur wird Polystyrol von nicht ausgehärteten Epoxydharzen, die sich von Dian oder anderen aromaten Grundkörpern herleiten, angelöst. Amidoaminharze auf Basis von di- und polymerisierten Fettsäuren als Härter zu Epoxydharzen geben Gewähr dafür, daß während der Aushärtung die Temperatur von 60° C nicht überschritten wird. ff Erfindungsgemäß hergestellt werden die Bauelemente, indem beispielsweise eine Platte aus Schaumstoff auf Polystyrolbasis zunächst mit einem Gemisch aus Epoxyharz und dem Härter mittels eines Spachtels bestrichen wird. Danach werden Faserschichten, z. B. Kunststoffgewebe, Fasern verschiedener Art, Glasfasern, Glasmatten oder Glasgewebe, aufgebracht, die wiederum mit Harzgemisch bedeckt werden. Zur Erzielung glatter Oberflächen genügt Spachtelung, jedoch können die Bauelemente auch im Preßverfahren hergestellt werden. Nach Aushärtung des Epoxyharz-Härter-Gemisches ist das Bauelement gebrauchsfähig.The usability of epoxy resins on polystyrene is limited to curing temperatures of the resin below 60 ° C. Above this temperature Polystyrene is made from uncured epoxy resins that are different from Dian or others Derive aromatic base bodies, dissolved. Amidoamine resins based on di- and polymerized fatty acids as hardeners to epoxy resins guarantee that during the curing temperature does not exceed 60 ° C. ff according to the invention The components are produced by, for example, a foam sheet based on polystyrene initially with a mixture of epoxy resin and the hardener with a spatula. Thereafter, fiber layers, e.g. B. plastic fabric, Fibers of various types, glass fibers, glass mats or glass fabrics, applied to the again covered with resin mixture. Sufficient to achieve smooth surfaces Filling, however, the components can also be produced using the pressing process. After the epoxy resin-hardener mixture has cured, the component is ready for use.
Die erfindungsgemäßen Bauelemente sind von sehr geringem Gewicht. In Form der Platten sind sie elastisch und können durch Biegung in die gewünschte Form gebracht werden. Stangen und Rohren auf der erfindungsgemäßen Basis sind dagegen hohe Steifigkeit, ausgezeichnete Festigkeit bei Beanspruchung auf Biegung, Zug, Druck und Stoß zu eigen. Die erfindungsgemäß hergestellten Bauelemente sind ferner wasserabweisend, chemisch weitgehend beständig und gut isolierend gegen Wärme, Kälte und Schall. Sie weisen eine glatte und glänzende Oberfläche auf, so daß sich eine zusätzliche Lackierung erübrigt. Dem Laminat können auch zur Erzielung farbiger Oberflächen Pigmente zugesetzt werden. Ein bedeutender Vorteil besteht noch darin, daß die Festigkeit der Bauelemente vorausberechnet bzw. die Dimensionen der Bauelemente auf die geforderten Festigkeiten abgestimmt werden können, was bei den meisten bekannten Kunststoffteilen erhebliche Schwierigkeiten bereitet.The components according to the invention are very light in weight. In the form of the plates, they are elastic and can be bent into the desired shape Be brought into shape. Rods and tubes based on the invention are against it high rigidity, excellent strength when subjected to bending, tension, Pressure and shock own. The components produced according to the invention are also water-repellent, chemically largely resistant and well insulating against heat and cold and sound. They have a smooth and shiny surface, so that a additional painting is not necessary. The laminate can also be used to achieve more colored Surface pigments are added. Another important advantage is that that the strength of the components or the dimensions of the components are calculated in advance can be matched to the required strengths, which is what most known Plastic parts causes considerable difficulties.
