Abstract
(EN)
The invention provides a process for the production of thermoplastic resin compositions by which a thermoplastic resin composition comprising a thermoplastic resin and a cellulose nanofiber can be obtained; and a process for the production of moldings by using the composition. The thermoplastic resin composition can be obtained by mixing an aqueous dispersion of a cellulose nanofiber with a thermoplastic resin (such as polylactic acid resin) in an agitator. It is preferable that the agitator be provided with a mixing chamber and the water contained in the aqueous dispersion be vaporized by mixing to pressurize the inside of the mixing chamber. Further, moldings can be obtained by extrusion- or injection-molding the thermoplastic resin composition.

L'invention porte sur un procédé de fabrication de compositions de résine thermoplastique suivant lequel une composition de résine thermoplastique comprenant une résine thermoplastique et des nanofibres de cellulose peut être obtenue; et sur un procédé de fabrication de pièces moulées à l'aide de la composition. La composition de résine thermoplastique peut être obtenue par mélange d'une dispersion aqueuse de nanofibres de cellulose avec une résine thermoplastique (telle qu'une résine d'acide polylactique) dans un dispositif d'agitation. On préfère que le dispositif d'agitation soit doté d'une chambre de mélange et que l'eau contenue dans la dispersion aqueuse soit vaporisée par mélange pour mettre sous pression l'intérieur de la chambre de mélange. De plus, des pièces moulées peuvent être obtenues par moulage par extrusion ou par injection de la composition de résine thermoplastique.
