Claims (4)
- Patentansprüche:
1. Pentaerythritdiphosphate von Amino-s-triazinen der allgemeinen Formel+ NH3N NP—Oin der X eine Amino- oder Hydroxylgruppe bedeutet - 2. Verfahren zur Herstellung der Verbindungen nach Anspruch 1, dadurch gekennzeichnet, daß man ein Gemisch aus Melamin und/oder Ammelid und einem Pentaerythritdichiorophosphat in einem Mclverhältnis von etwa 2 :1 in Gegenwart von Wasser unter Rückfluß erhitzt
- 3. Verwendung der Verbindungen nach Anspruch 1 als flammhemmende Zusätze für Polyolefinmass°n.
- 4. Verwendung der Verbindungen nach Anspruch 1, dadurch gekennzeichnet, daß man 20 bis 50 Gewichtsprozent, bezogen auf die Gesamtmasse der Polyolefinmassen, Melammoniumpentaerythritdiphosphat und/ oder das Pentaerythritdiphosphat von Ammelid als flammhemmende Zusätze einsetztPolyolefine lassen sich im allgemeinen nur schwer flammfest ausrüsten. Es ist zwar eine Anzahl von halogenhaltigen fiammhemmenden Zusätzen bekannt, die beim Einarbeiten in Polyolefine nicht brennbare Massen ergeben, d. h. Materialien, auf denen sich die Flammen nicht ausbreiten. Polyolefine, wie Polypropylen, haben jedoch die Neigung, brennende Tropfen auszubilden und die nicht-brennbaren Massen können im allgemeinen nicht vollständig selbstverlöschend gemacht werden.Eine alternative Lösung besteht im Zusatz von kohlebildenden Additiven, die in Gegenwart einer Flamme ■er-e dicke nicht brennbare isolierende Sperrschicht ausbilden, welche das Polymersubstrat schützt Ein derartiges blähendes oder kohlebildendes System in Form einer Kombination aus Melaminpyrophosphat und einem Polyol ist in der US-PS 39 36 416 beschrieben. Diese Additivkombination eignet sich zur Herstellung einer nicht brennbaren, nicht tropfenden Polypropylenmasse. D?s Hersteller, und Kcmpoundieren dieser Materialien ist jedoch schwierig. Während der Herstellung muß die Additivkombination entgast werden, um während des Kompoundierens mit Polypropylen und/oder in den anschließenden Formverfahren ein Schäumen zu vermeiden. Außerdem hat das erhaltene Additiv eine bernsteinfarbene oder braune Farbe, die der Polypropylenmasse einen unerwünschten Farbton verleiht und fällt in Form einer harten festen Masse an, die sich nur schwer pulverisieren läßt.Aufgabe der Erfindung ist es daher, blähende flammhemmende Zusätze für Polyolefine bereitzustellen, die bei der Verarbeitungstemperatur nur wenig oder keine Schaumbildung zeigen, leicht in verwendbarer Form herstellbar sind und keine unerwünschte Dunkelfärbung ergeben.Amino-s-triazine der Formel
