Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Herstellung eines Polyisocyanurat-Kompositwerkstoffs, umfassend die folgenden Schritte: a) Bereitstellen einer Polyisocyanatzusammensetzung A), welche oligomere Polyisocyanate enthält und arm an monomeren Diisocyanaten ist, wobei arm an monomeren Diisocyanaten bedeutet, dass die Polyisocyanatzusammensetzung A) einen Gehalt an monomeren Diisocyanaten von höchstens 20 Gew.-% aufweist, und b) katalytische Trimerisierung der Polyisocyanatzusammensetzung A) in Gegenwart mindestens eines faserförmigen Füllstoffs B) und eines Trimerisierungskatalysators C) zum Polyisocyanurat-Kompositwerkstoff, wobei der Trimerisierungskatalysator C) mindestens ein quaternäres Ammonium- und/oder Metallsalz und umfasst. Ferner betrifft die Erfindung Polyisocyanurat-Kompositwerkstoffe, erhältlich nach dem erfindungsgemäßen Verfahren und deren Verwendung zur Herstellung eines Bauteils sowie Bauteile, bestehend aus oder enthaltend einen erfindungsgemäßen Polyisocyanurat-Kompositwerkstoff.
(EN)
The invention relates to a method for producing a polyisocyanurate composite material, comprising the following steps: a) providing a polyisocyanate composition A) which contains oligomer polyisocyanates and is low in monomer diisocyanates, where ‘low in monomer diisocyanates’ means that the polyisocyanate composition A) has a monomer diisocyanate content of no more than 20 wt.%, and b) catalytically trimerising said polyisocyanate composition A) in the presence of at least one fibrous filler material B) and a trimerisation catalyst C) to obtain the polyisocyanurate composite material, said trimerisation catalyst C) comprising at least one quaternary ammonium salt and/or metal salt. The invention also relates to polyisocyanurate composite materials that can be obtained according to the claimed method, and to the use of same to produce a component and components consisting of or containing a claimed polyisocyanurate composite material.
(FR)
L'invention concerne un procédé de préparation d'un matériau composite à base de polyisocyanurate comprenant les étapes suivantes consistant à : a) utiliser une composition de polyisocyanate (A) qui contient des polyisocyanates oligomères et est pauvre en diisocyanates monomères, pauvre en diisocyanates monomères signifiant que la composition de polyisocyanate (A) présente une teneur en diisocyanates monomères d'au plus 20 % en poids, et b) effectuer une trimérisation catalytique de la composition de polyisocyanate (A) en présence d'au moins une charge fibreuse (B) et d’un catalyseur de trimérisation (C) pour obtenir ledit matériau composite à base de polyisocyanurate, le catalyseur de trimérisation (C) présentant au moins un sel d’ammonium quaternaire et/ou métallique. L'invention concerne en outre des matériaux composites à base de polyisocyanurate pouvant être obtenus selon le procédé de l'invention, et leur utilisation pour la fabrication d'une pièce, ainsi que des pièces constituées d’un matériau composite à base de polyisocyanurate ou contenant un matériau composite à base de polyisocyanurate selon l'invention.
