Title
(EN) A METHOD TO DISPERSE NANO-CELLULOSE IN ORGANIC POLYMER PRECURSORS
(FR) PROCÉDÉ DE DISPERSION DE NANOCELLULOSE DANS DES PRÉCURSEURS DE POLYMÈRE ORGANIQUE
Abstract
(EN) This invention concerns a novel method to produce thermosets such as epoxies and polyurethanes comprising nano-cellulose. The method comprises contacting primarily water-bourne dispersed nano-cellulose with liquid thermoset precursors, specifically epoxy or amine in the case of epoxies, or glycols or similar in the case of polyurethanes. Nano-cellulose transfers to the organic phase, and water is removed at temperatures below 100 °C. Thereafter the organic phase comprising nano-cellulose can be mixed with the reactive counterpart to yield nano-composites with improved properties. The products can be used for composite articles, coatings, adhesives, sealants, and other end-uses. Preferred embodiments are described in detail.
(FR) La présente invention concerne un nouveau procédé pour produire des résines thermodurcissables telles que des époxydes et des polyuréthanes comprenant de la nanocellulose. Le procédé comprend la mise en contact de nanocellulose dispersée principalement aqueuse avec des précurseurs liquides de résine thermodurcissable, spécifiquement de l'époxy ou de l'amine dans le cas d'époxydes, ou de glycols ou similaires dans le cas de polyuréthanes. La nanocellulose passe dans la phase organique et l'eau est éliminée à des températures inférieures à 100°C. Ensuite, la phase organique comprenant la nanocellulose peut être mélangée avec la contrepartie réactive pour produire des nanocomposites présentant des propriétés améliorées. Les produits peuvent être utilisés pour des articles, des revêtements, des adhésifs, des agents d'étanchéité composites et d'autres utilisations finales. Des modes de réalisation préférés sont décrits en détail.
