Abstract
The present application provides a dispersion dispersed satisfactorily cellulose nanofibers, powdery cellulose nanofibers obtained by pulverizing thereof, a resin composition obtained by blending thereof and a molding raw material for a 3D printer by using thereof. It is possible to obtain a composition uniformly finely dispersed the cellulose nanofibers by treating a mixture containing unmodified cellulose nanofibers and a dispersant using a high speed agitating Medialess disperser, and followed by pulverizing the composition to blend with a resin and a rubber component. Also, a resin composition improved in mechanical properties and heat resistance, obtained by blending the powdery cellulose nanofibers above with a thermoplastic resin or a thermosetting resin, is useful as a molding material for a 3D printer.
