Description
Schwerentflammbare und selbstverlöschende Formmassen Zusatz zu Patent (Patentanmeldung P 22 49 910.1) Flame-resistant and self-extinguishing molding compounds Addition to patent (patent application P 22 49 910.1)
Die Erfindung betrifft flammschutzmittelhaltige Formmassen aus Polybutylenterephthalat, die selbstverlöschend und nicht tropfend sind.The invention relates to flame retardant-containing molding compositions made from polybutylene terephthalate, which are self-extinguishing and non-dripping are.
Gegenstand des Patentes (Patentanmeldung P 22 49 910.1)Subject of the patent (patent application P 22 49 910.1)
sind schwerentflammbare und selbstverlöschende Formmassen auf Basis von Polybutylenterephthalat, die dadurch gekennzeichnet sind, daß sie 0,5 bis 15 Gewichtsteile, vorzugsweise 2 bis 8 Gewichtsteile, bezogen auf 100 Gewichtsteile Polyester, fein- , verteilten roten Phosphor sowie einen inerten Füllstoff, vorzugsweise Asbest, enthalten.are flame-retardant and self-extinguishing molding compounds based on polybutylene terephthalate, which are characterized by are that they are 0.5 to 15 parts by weight, preferably 2 to 8 parts by weight, based on 100 parts by weight of polyester, fine, distributed red phosphorus and an inert filler, preferably asbestos.
Es wurde nun gefunden, daß sich schwerentflammbare und selbstverlöschende Formmassen des Patentes (PatentanmeldungIt has now been found that flame retardant and self-extinguishing Molding compounds of the patent (patent application
P 22 49 910.1) verbessern lassen, wenn sie als inerten Füllstoff Asbest und Glasfasern enthalten.P 22 49 910.1) can be improved if they contain asbestos and glass fibers as inert fillers.
Es hat sich gezeigt, daß man eine besonders gute Flammfestausrüstung von Polybutylenterephthalat erhält, wenn die Formmassen, bezogen auf 100 Gewichtsteile Polyester, 2 bis 8 Gewichtsteile roten Phosphor, 2 bis 10 Gewichtsteile Asbest und 1£ bis 40 Gewichtsteile Glasfasern enthalten.It has been shown that a particularly good flame retardant finish can be obtained obtained from polybutylene terephthalate when the molding compositions, based on 100 parts by weight of polyester, 2 to 8 parts by weight of red phosphorus, 2 to 10 parts by weight of asbestos and 1 £ to Contains 40 parts by weight of glass fibers.
Als Glasfasern kommen insbesondere solche in Frage, die aus einem alkaliarmen Ε-Glas'hergestellt wurden. Der Durchmesser der Glasfasern liegt zwischen 5 und 25/um, bevorzugt zwischen. 8" und 15 /Ui. Ihre Länge in den Formmassen beträgt 0,05 bis 1,0 mm, bevorzugt 0,1 bis 0,5 mm.Particularly suitable glass fibers are those which have been produced from low-alkali Ε-glass. The diameter of the glass fibers is between 5 and 25 μm, preferably between. 8 "and 15 / Ui. Their length in the molding compounds is 0.05 to 1.0 mm, preferably 0.1 to 0.5 mm.

Die Einarbeitung der Glasfasern kann nach bekannten Verfahren (z.B. nach dem U.S. Patent 3 304 282) erfolgen, wobei endlose Glasfaserrovings oder geschnittene Glasseide eingesetzt werden können.The incorporation of the glass fibers can be carried out according to known methods (e.g. according to U.S. Patent 3,304,282), endless Fiberglass rovings or cut fiberglass can be used.
Von den Asbestarten eignen sich insbesondere faserförmige Asbestsorten, bevorzugt Chrysotylasbeste.Of the asbestos types, fibrous asbestos types are particularly suitable, prefers chrysotyl asbestos.
Die erfindungsgemäßen Formmassen auf der Basis Polybutylenterephthalat haben eine wesentlich bessere flammwidrige Eigenschaft als Formmassen, die entweder nur Glasfasern und roten Phosphor oder nur Asbest und roten Phosphor in den gleichen Mengenverhältnissen enthalten.The molding compositions according to the invention based on polybutylene terephthalate have a much better flame-retardant property than molding compounds, which either only have glass fibers and red phosphorus or contain only asbestos and red phosphorus in the same proportions.
Der Vorteil im Brandverhalten zeigt sich insbesondere, wenn man zu dünnwandigen Formkörpern (3 mm und dünner) übergeht und diese senkrecht hängend der Flammprüfung unterzieht. Während Formkörper aus Formmassen, die sowohl roten Phosphor, Glasfasern und Asbest enthalten, sofort nach Wegnahme der Zündflamme ohne Abtropfen verlöschen, brennen die Mischungen, die lediglich roten Phosphor und Glasfasern oder lediglich roten Phosphor und Asbest enthalten, noch einige Zeit weiter, wobei Teile des Prüfkörpers abtropfen.The advantage in fire behavior is particularly evident when one to thin-walled moldings (3 mm and thinner) and subject them to the flame test hanging vertically. While molded body from molding compounds that contain both red phosphorus, glass fibers and asbestos, immediately after removing the pilot light without dripping go out, burn the mixtures that contain only red phosphorus and glass fibers or only red phosphorus and Contained asbestos for some time, with parts of the test specimen dripping off.
Für die Herstellung der erfindungsgemäßen Formmassen eignen sich Polybutylenterephthalate mit den gleichen Eigenschaften wie sie im Hauptpatent beschrieben sind.Polybutylene terephthalates with the same properties are suitable for the production of the molding compositions according to the invention as described in the main patent.
Die Prüfung des Brandverhaltens erfolgt in Anlehnung an den Uli-Test 94 (Underwriter Laboratories) an 3,2 mm dicken gespritzen Prüfkörpern.The fire behavior test is based on Uli-Test 94 (Underwriter Laboratories) on 3.2 mm thick syringes Test specimens.
Die Vorteile der erfindungsgemäßen Mischung werden durch das folgende Beispiel veranschaulicht.The advantages of the mixture according to the invention are illustrated by the following example.

In einem Mischextruder wird Polybutylenterephthalat mit einer relativen Viskosität von 1,65 (gemessen in 0,5 $iger Lösung bei 250C in einem Phenol-o-chlorbenzol-Gemisch (3 : 2) mit Hilfe eines Ubelhode Viskosimeters) aufgeschmolzen. Durch eine Öffnung im Gehäuse des Extruders werden stromabwärts die in der folgenden Tabelle angegebenen Zusatzstoffe eingebracht. Die Mischung wird durch Düsen ausgepreßt, als Strang abgezogen und granuliert. Aus dem Granulat werden Prüfkörper der Abmessung 63,5 x 12,7 x 3,2 mm gespritzt.In a mixing extruder is polybutylene terephthalate having a relative viscosity of 1.65 (measured in 0.5 $ strength by weight solution at 25 0 C in a phenol-o-chlorobenzene mixture (3: 2) using a viscometer Ubelhode) melted. The additives indicated in the following table are introduced downstream through an opening in the housing of the extruder. The mixture is pressed out through nozzles, drawn off as a strand and granulated. Test specimens measuring 63.5 x 12.7 x 3.2 mm are injected from the granulate.
Die Ergebnisse sind in der Tabelle zusammengefaßt.The results are summarized in the table.
