Abstract
Formteile aus Kunststoff, deren Oberfläche ganz oder teilweise mit einer Brandschutzschicht bedeckt sind, und Verfahren zur Herstellung durch Beschichtung des Formteils mit einer Brandschutzdispersion oder einem Brandschutzlack.Molded parts made of plastic, the surface of which is completely or partially covered with a fire protection layer, and process for the production by coating the molded part with a fire protection dispersion or a fire protection lacquer.
Description
Die Erfindung betrifft Formteile aus Kunststoff deren Oberfläche ganz oder teilweise mit einer Brandschutzschicht bedeckt sind.The invention relates to molded parts made of plastic whose surface completely or partially covered with a fire protection layer.
Kunststoffe entzünden sich bei Flammeneinwirkung
und brennen auch nach dem Entfernen der Zündquelle weiter. Daher werden
für Anwendungen im
Elektro- oder Bausektor spezielle flammgeschützte thermoplastische Formmassen
mit deutlich verbessertem Brennverhalten eingesetzt. Diese könne halogenfreie
oder halogenhaltige Flammschutzmittel enthalten. Halogenfrei flammgeschützte Polystyrolformmassen
sind beispielsweise in
Die eingesetzten Flammschutzmittel können jedoch je nach Art und Menge die mechanischen Eigenschaften und die Wärmeformbeständigkeit der thermoplastischen Formmassen herabsetzen.The flame retardants used can however depending on the type and quantity, the mechanical properties and heat resistance reduce the thermoplastic molding compounds.
Aufgabe der vorliegenden Erfindung war es daher, flammgeschützte Formteile aus Kunststoff bereitzustellen, die die vorgenannten Nachteile nicht aufweisen und insbesondere einen ausreichenden Brandschutz bei geringem Flammschutzmitteleinsatz aufweisen. Des weiteren sollte ein einfaches und kostengünstiges Verfahren gefunden werden, das die Herstellung und auch die nachträgliche Ausrüstung von Formteilen aus Kunststoff mit Flammschutz ermöglicht.Object of the present invention it was therefore flame retardant To provide molded plastic parts that have the aforementioned disadvantages do not have and in particular adequate fire protection with low use of flame retardants. Furthermore, should a simple and inexpensive Processes are found that the manufacture and also the subsequent equipment of Molded parts made of plastic with flame protection enabled.
Dem gemäß wurden Formteile aus Kunststoff gefunden, deren Oberfläche ganz oder teilweise mit einer Brandschutzschicht bedeckt wird. Je nach Anwendung kann es ausreichend, beispielsweise nur die Außenseite eines Formteiles mit der Brandschutzschicht zu bedecken.Accordingly, molded parts were made of plastic found whose surface completely or partially covered with a fire protection layer. ever depending on the application, it may be sufficient, for example only the outside to cover a molded part with the fire protection layer.
Die Dicke der Brandschutzschicht ist deutlich geringer als die Dicke des Formteils, insbesondere beträgt die Dicke der Brandschutzschicht weniger als 10% der Gesamtdicke des Formteils und liegt in der Regel z. B. für Elektrogerätegehäuse im Bereich von 1 bis 500 μm, bevorzugt im Bereich von 10 mm bis 250 μm liegt.The thickness of the fire protection layer is significantly less than the thickness of the molded part, in particular the thickness is the fire protection layer less than 10% of the total thickness of the molded part and is usually z. B. for Electrical device housing in the area from 1 to 500 μm, is preferably in the range from 10 mm to 250 μm.
Als Brandschutzschicht eigenen sich alle Folien, Laminate, Gitter, Netze oder Anstriche, die üblicherweise zum Brandschutz von Stahl- oder Holzkonstruktionen eingesetzt werden. Die Brandschutzschicht kann die üblicherweise verwendeten halogenhaltigen, z. b., organische Chlor- oder Bromverbindungen oder halogenfreie Flammschutzmittel, wie Phosphor, organische Phosphor- und Stickstoffverbindungen enthalten. Bevorzug te Flammschutzmittel sind solche, die bei Hitzeeinwirkung Wasser, CO2 oder N2 abspalten, wie Carbonsäuren und deren Derivate oder anorganische Salze, wie Calcium- oder Ammoniumcarbonat, Aluminium-, Magnesium, Calicum oder Bariumhydroxid oder wasserhaltiges Natriumsilikat..All films, laminates, grids, nets or paints that are normally used for fire protection of steel or wooden structures are suitable as fire protection layers. The fire protection layer can contain the commonly used halogen-containing, for example, organic chlorine or bromine compounds or halogen-free flame retardants such as phosphorus, organic phosphorus and nitrogen compounds. Preferred flame retardants are those which release water, CO 2 or N 2 when exposed to heat, such as carboxylic acids and their derivatives or inorganic salts, such as calcium or ammonium carbonate, aluminum, magnesium, calcium or barium hydroxide or water-containing sodium silicate.
Die Brandschutzschicht wird so gewählt, dass ein Prüfkörper im Brennbarkeitstest nach UL die Kriterien der Brandschutzklasse V2, V1 oder VO erfüllt.The fire protection layer is chosen so that a test specimen in Flammability test according to UL the criteria of fire protection class V2, V1 or VO fulfilled.
Die Formteil können aus duroplastische und thermoplastische Kunststoffen bestehen. Besonders wichtig ist die Brandschutzausrüstung für die leicht entflammbareren Thermoplastischen Kunststoffe, wie Styropolymere, insbesondere Standard (GPPS)- oder Schlagzäh-Polystyrol (HIPS) und Acrylnitril-Butadien-Styrol-Polymere (ABS) oder Polyolefine, wie Polypropylen, Polyethylen oder Copolymere.The molded part can be made of thermosetting and thermoplastic Plastics exist. Fire protection equipment is particularly important for the more flammable ones Thermoplastic plastics, such as styrenic polymers, in particular standard (GPPS) - or impact-resistant polystyrene (HIPS) and acrylonitrile-butadiene-styrene polymers (ABS) or polyolefins, such as polypropylene, polyethylene or copolymers.
Die Brandschutzschicht kann als Laminat, Folie, Dispersion oder Lösung auf das Formteil aufgebracht werden. Bevorzugt wird das Formteil aus Kunststoff mit einer Brandschutzdispersion oder einem Brandschutzlack beschichtet. Die Beschichtung kann durch Sprühen, Tauchen, Rollen oder Streichen auf einer oder mehreren Oberflächen des Formteils aufgetragen werden.The fire protection layer can be used as a laminate, foil, Dispersion or solution be applied to the molded part. The molded part is preferred made of plastic with a fire protection dispersion or a fire protection lacquer coated. The coating can be applied by spraying, dipping, rolling or brushing one or more surfaces of the molded part are applied.
Die Brandschutzdispersion oder der Brandschutzlack können auf Basis Polyvinylchlorid, Polyvinylchlorid-Ethylen-Copolymer, Melamine-Formaldehyd, Polyacrylat, Polyurethan oder Epoxid und sowohl lösungsmittelhaltig oder wasserverdünnbar sein. Ebenfalls möglich sind flammschutzmittelhaltige Pulverlacke. Bevorzugte Brandschutzdispersionen oder Brandschutzlacke bestehen aus chemisch vernetzenden Komponenten, die thermisch bei niedrigen Temperaturen oder mittels UV- oder Elektronenstrahlen vernetzt werden können. Neben den genannten Flammschutzmittel können die Brandschutzdispersionen oder Brandschutzlacke übliche Farbstoffe, Pigmente, Füllstoffe, Weichmacher, Verdicker, Verlaufshilfsmittel, Haftvermittler oder Stabilisatoren enthalten.The fire protection dispersion or the Fire protection paint can based on polyvinyl chloride, polyvinyl chloride-ethylene copolymer, Melamine formaldehyde, polyacrylate, polyurethane or epoxy and both contains solvents or be water-dilutable. Also possible are powder coatings containing flame retardants. Preferred fire protection dispersions or fire protection lacquers consist of chemically cross-linking components, the thermally at low temperatures or by means of UV or electron beams can be networked. In addition to the flame retardants mentioned, the fire protection dispersions or fire protection lacquers, common dyes, Pigments, fillers, Plasticizers, thickeners, flow control agents, adhesion promoters or Stabilizers included.
Die erfindungsgemäßen Formteile mit Brandschutzschicht können insbesondere in Computen, Computerperipheriegeräten, Television (TV)- oder Musikgeräten eingebaut werden.The molded parts according to the invention with a fire protection layer can especially in computers, computer peripheral devices, television (TV) - or music devices to be built in.
