Abstract

The invention aims 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 powderycellulose 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 anduniformly 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.

Description

technical field

[0001] The present invention relates to a dispersion in which nanofibers such as cellulose nanofibers are well dispersed, a method for producing the dispersion, powdery nanofibers obtained by drying the dispersion, a resin composition in which the nanofibers are uniformly dispersed, and a method using the dispersion. A resin composition molding material for 3D printers. Background technique

[0002] In cellulose, which is naturally abundant biomass, nanofibers are bundled to form a fibrous structure, and function mainly as a strong structural material of plants. In such a structural material of cellulose fibers, the surfaces of the nanofibers are firmly bundled mainly by the bonding force through hydrogen bonds, so it is difficult to disperse the original state of the nanofibers.

[0003] Therefore, Patent Document 1 proposes a dispersion of cellulose nanofibers obtained by subjecting a dispersion containing cellulose nanofibers and an anionic dispersant to ...
