The present invention obtains a dispersion in which cellulose nanofibers are well dispersed, powdery cellulose nanofibers obtained by pulverizing the same, a resin composition obtained by blending the powdery cellulose nanofibers into a resin, and using the same Resin composition molding material for 3D printers. By treating the mixture containing the unmodified cellulose nanofibers and the dispersant together with water in a high-speed stirring type medium-free dispersion type, a stable dispersion of the cellulose nanofibers is obtained, and the dispersion is further powderized and then compounded into a resin or a resin. In the rubber component, a composition in which the cellulose nanofibers are uniformly and finely dispersed is obtained. In addition, a resin composition with improved mechanical properties and heat resistance obtained by blending the powdered cellulose nanofibers into a thermoplastic resin or a thermosetting resin can be used as a molding material for 3D printers. |
