Description
Formmassen und daraus hergestellte flammfeste Werkstücke Kunstsotffe finden wegen ihres relativ niedrigen Preises. Molding compounds and flameproof workpieces made from them, Kunstsotffe find because of their relatively low price.
ihres geringen Gevichtes und ihrer guten Verarbeitbarkeit in zunehmendem Maße im Bauwessen, z.B. als Isolierstoff, für die Außen- und Innenausstattung von Häusern bzw. Räumen.their low weight and their good processability in increasing Dimensions in construction, e.g. as insulating material, for the exterior and interior of Houses or rooms.
z.B. als Boden-, Wand- oder Deckenverkleidung und in der Möbelindustrie weite Verbreitung. Als wesentlicher Nachteil für diese einsatzgebiete ist jedoch die leichte Brennbarkeit solcher Stoffe zu werten. Es fehlte daher nicht an Bemühungen, die Brennbarkeit solcher Stoffe durch verschliedene Zusätze herabzusetzen oder diese gar flammfest zu machen.e.g. as floor, wall or ceiling cladding and in the furniture industry wide spread. However, a major disadvantage for these areas of application is to evaluate the easy flammability of such substances. There was therefore no lack of efforts to reduce the flammability of such substances through various additives or these to make even flame-proof.
Eine geringe Brennbarkeit wird bei Polyurethanen und Epoxyharzen z.B. durch Zumischen von größeren Mengen an anorganischen Füllstoffen, wie z.B. Kreise erzielt, was jedoch eine Erhöhung des Gewichtes und eine Verschlechterung der Eigenschaften bedeutet.Low flammability is found in polyurethanes and epoxy resins e.g. by adding larger amounts of inorganic fillers, such as circles achieved, which, however, is an increase of weight and deterioration which means properties.
Es konnte nun überraschenderweise gefunden werden, daß der nicht brennbare organische Stoff Melamin mit Polyurethanen und Epoxyharzen Mischungen gibt, die durch Ubliche Verarbeitungsmethoden, z.B. Verpressen verformbar sind und bei einem Gehalt an Melamin von 0,66 - 3 Teilen pro Teil Polyurethan bzv. Epoxyharz auch selbst verschlöschen (nach ASTM 635 - 63).It has now surprisingly been found that the non-combustible organic substance melamine with polyurethanes and epoxy resins mixtures there that are deformable by common processing methods, e.g. pressing and with a Melamine content of 0.66 - 3 parts per part of polyurethane or Epoxy resin itself too extinguish (according to ASTM 635 - 63).
Trotzt des relativ niedrigen Gehaltes an den genannten Kunststoffen besitzen solche Mischungen eine ftlr viele Zvecke ii Bauwesen ausreichende Festigkeit. Damit konnte eine Formmasse zur Herstellung von flammfesten Werkstücken geschaffen werden, die sich in erster Linie für den Xasseneinsatz im Bauwesen und auf dem Gebiet der Innenausstattung eignet, da sie den Vorteil einer Flammfestigkeit mit leichtem Gewicht und keinerlei Gefahr einer Entwicklung Atzender Gase bei Schvelbrändern verbindet, Gegenstand der vorliegenden Erfindung sind demnach Formmassen und daraus hergestellte flammfeste Werkstücke auf Basis von Polyurethanen und Epoxyharzen, dadurch gekennzeichnet, daß sie die Reaktionsharzmasse des Kunstsstoffes, Melamin und gegebenenfalls die üblichen Füllstoffe, Farbstoffe und Verstärkungsfahren enthalten, wobei auf 1 Teil Reaktionsharzmasse 0,66 bis 3 Teile Melamin kommen.Despite the relatively low content of the plastics mentioned Such mixtures have sufficient strength for many purposes in construction. This made it possible to create a molding compound for the production of flame-resistant workpieces which are primarily for use in construction and in the field The interior decoration is suitable as it has the advantage of being flame resistant with a light weight Weight and no risk of the development of corrosive gases in the event of a fire connects, the subject of the present invention are accordingly molding compositions and from them Manufactured flame-retardant workpieces based on polyurethane and epoxy resins, characterized in that it is the reaction resin compound of the plastic, melamine and optionally contain the usual fillers, dyes and reinforcement processes, 0.66 to 3 parts of melamine are added to 1 part of reaction resin compound.
Unter Polyurethan und Epoxydharzen sind alle handelsüblichen Kunststoffe zu verstehen, die die charakteristischen Urethan-bzw. Epoxygruppen im NolekUl enthalten. Die Natur dieser Harze ist von geringen Einfluß, da der Harzanteil gegenüber den Melamin zurticktritt.Polyurethane and epoxy resins include all commercially available plastics to understand that the characteristic urethane or. Contain epoxy groups in the NolekUl. The nature of these resins is of little influence, since the resin content compared to the Melamine ticks off.
Die Herstellung der erfindungsgemäßen Werkstücke gelingt einfach dadurch, daß eine oder beide Komponenten des tunststoffes mit pulverförmigem Melamin in einer Menge gemischt werden, daß auf 1 Teil Reaktionsharzmasse 0,66 bls 3 Teile Melamin kommen, vorauf die Komponentendes Kunststoffes in der für den verwendeten Kunststoff üblichen Weise gemischt, gegebenenfalls mit den üblichen Füllstoffen, Farbstoffen, Schäummitteln und Verstärkungsfasern verarbeitet teilweise oder zur Gänze ausgehärtet werden.The workpieces according to the invention can be produced simply by that one or both components of the plastic with powdered melamine in one Amount to be mixed that to 1 part reaction resin mass 0.66 bls 3 parts melamine come before the components of the plastic in those for the plastic used mixed in the usual way, if necessary with the usual fillers, dyes, Foaming agents and reinforcing fibers processed partially or fully cured will.
So können z.B. aus Epoxydharz-Melamingemischen entweder Formen ausgefüllt oder Glasfasematten bestrichen werden, die dann dem Kunststoff entsprechend durch Zusatz von Härtern und gegebenenfalls unter erhitzen ausgehärtet werden. Wird eine solche Masse nur bis zu einem bestimmten Grad t.B. in der Kalte gehärtet, erhält man stabile Formmassen, die vom letztverbraucher verformt und engültig gehärtet werden können (sog. Prepregs).For example, either forms can be filled out of epoxy resin-melamine mixtures or glass fiber mats are coated, which are then passed through according to the plastic Addition of hardeners and, if necessary, hardened with heating. Will be a such mass only up to a certain degree t.B. hardened in the cold stable molding compounds that are deformed and finally hardened by the end user can be (so-called prepregs).
Es ist auch möglich, den Mischungen ein übliches Schäummittel, z. B. Frigen zuzusetzen, sodaß erfindungsgemäß geschäunte Produkte erhalten werden. die vielfältige Einsatzmöglichkeiten für Füllstoffe oder zur Wärme- und Schalldämmung besitzen.It is also possible to add a customary foaming agent, e.g. B. to add Frigen, so that peeled products according to the invention are obtained. the many possible uses for fillers or for heat and sound insulation own.
Die erfindungsgemäßen Formmassen bzw. Werkstücke und deren Herstellung werden anschließend in den Beispielen näher beschrieben. ohne daß diese Beispiele die Erfindung beschränken sollen.The molding compositions or workpieces according to the invention and their production are then described in more detail in the examples. without these examples intended to limit the invention.

Das eingesetzte Melamin hat eine Korngrößenverteilung von 0,8 % , 100 µ, 10 % 100 - 60 p, 43,6 % 60 - 25 und 45,6 % < 25 In einer of£enen Form schäumt dieses Gemisch nach ca.Example 1: 40 parts of a commercially available polyurethane component I are mixed with 23 parts of melamine, concentrated to 7 parts of Frigen and finally nor a mixture of 48 parts of a commercially available polyurethane component II and 72 parts powdered melamine stirred in. The melamine used has a particle size distribution from 0.8%, 100 µ, 10% 100 - 60 p, 43.6% 60 - 25 and 45.6% <25 in one open Mold, this mixture foams after approx.
20 sec. zu eine feinporigen Schaum auf.20 sec. To a fine-pored foam.
Brennbarkeitsprüfung nach ASTM 635 - 63 ergibt 1 Sekunde.Flammability test according to ASTM 635 - 63 results in 1 second.
Verhältnis Polyurethan zu Melamin = 1 : 1,06.Polyurethane to melamine ratio = 1: 1.06.
