Title (EN) FOAMED ISOCYANATE-BASED POLYMER
(FR) POLYMÈRE MOUSSÉ À BASE D'ISOCYANATE
Abstract:
(EN) There is described a foamed isocyanate-based polymer derived from a reaction mixture comprising: an isocyanate; a polyol composition comprising a first prescribed amount of polymer particles dispersed in a base polyol; a second prescribed amount of biomass-based carbonaceous particulate material; and a blowing agent. In one embodiement, the foamed isocyanate-based polymer having an Indentation Force Deflection when measured pursuant to ASTM D3574-11 which is within about 15% as that of a reference foam produced by omitting the biomass-based carbonaceous particulate material from the reaction mixture and increasing the amount of polymer particles in the polymer polyol composition to equal the sum of the first prescribed amount and the second prescribed amount. In another embodiment, the foamed polymer has a cellular matrix comprising a plurality of interconnected struts, the biomass-based carbonaceous particulate material conferring to the cellular matrix a load efficiency of at least about 5 Newtons/weight % of biomass-based carbonaceous particulate material. A process to produce the foamed isocyanate-based polymer is also described. A polyol-based dispersion to produce the foamed isocyanate-based polymer is also described. It has been discovered that a relatively expensive petroleum-based copolymer polyol can be fully substituted by a relative inexpensive bio-based (amorphous carbon) dispersion with no significant compromise in important physical properties in the resulting polyurethane foam.
(FR) L'invention concerne un polymère moussé à base d'isocyanate dérivé d'un mélange de réaction comprenant : un isocyanate ; une composition de polyol comprenant une première quantité prescrite de particules de polymère dispersées dans un polyol de base ; une deuxième quantité prescrite de matériau particulaire carboné à base de biomasse ; et un agent gonflant. Dans un mode de réalisation, le polymère moussé à base d'isocyanate présente une déflexion de la force d'indentation, mesurée selon la norme ASTM D3574-11, qui est d'environ 15 % par rapport à celle d'une mousse de référence produite par omission du matériau particulaire carboné à base de biomasse du mélange de réaction et par augmentation de la quantité de particules de polymère dans la composition de polyol polymère pour qu'elle soit égale à la somme de la première quantité prescrite et de la deuxième quantité prescrite. Dans un autre mode de réalisation, le polymère moussé présente une matrice cellulaire comprenant une pluralité de supports interconnectés, le matériau particulaire carboné à base de biomasse conférant, à la matrice cellulaire, une efficacité de charge d'au moins environ 5 Newtons/% en poids de matériau particulaire carboné à base de biomasse. L'invention concerne également un procédé de production du polymère moussé à base d'isocyanate. L'invention porte également sur une dispersion à base de polyol pour produire le polymère moussé à base d'isocyanate. On a découvert qu'un polyol de copolymère à base de pétrole relativement coûteux peut être entièrement substitué par une dispersion à base biologique (carbone amorphe) relativement bon marché sans compromettre significativement les propriétés physiques importantes dans la mousse de polyuréthane obtenue.
