NANOFIBER DISPERSION, METHOD FOR PRODUCING NANOFIBER DISPERSION, POWDERY NANOFIBERS OBTAINED FROM DISPERSION, RESIN COMPOSITION INCLUDING SAID POWDERY NANOFIBERS, AND MOLDING MATERIAL FOR 3D PRINTER IN WHICH SAID RESIN COMPOSITION IS USED
Document Type and Number:
WIPO Patent Application WO/2017/141779
Kind Code:
A1
Abstract:
To obtain a dispersion in which cellulose nanofibers are dispersed well, powdery cellulose nanofibers obtained by powdering the dispersion, a resin composition in which the powdery cellulose nanofibers are blended into a resin, and a molding material for 3D printers in which the resin composition is used. A cellulose nanofiber stable dispersion is obtained by treating a mixture, which includes unmodified cellulose nanofibers and a dispersant, together with water by a high-speed stirring-type medialess disperser, and a composition in which cellulose nanofibers are finely and uniformly dispersed is obtained by powdering the dispersion and blending the same with a resin and a rubber component. In addition, a resin composition having improved mechanical properties and heat resistance, the resin composition being obtained by blending the powdered cellulose nanofibers with a thermoplastic resin or thermosetting resin, is also useful as a molding material for 3D printers.
