Document Type and Number:
WIPO Patent Application WO/2018/207945
Kind Code:
A1
Abstract:
[Problem] To provide a CNF molding device with which a CNF molded body having a 3-dimensional shape can be obtained.
[Solution] In a state in which a mold cavity 4 is formed by a bottom plate 3 and a body portion 2, cellulose nanofiber (CNF) is loaded into the mold cavity 4 from a nozzle 6 mounted to an upper plate 2b. At around the same time, heating of a mold portion 2a is started. In a state in which a certain amount or more of CNF has been accumulated in the mold cavity 4, the upper plate 2b is pressurized in the direction of the bottom plate 3, whereby the entire body portion 2 being supported in a movable state moves in the direction of the bottom plate 3, the bottom plate 3 is fitted into the mold portion 2a, and the volume of the mold cavity 4 decreases. In the process, the CNF in the heated mold portion 2a contracts while externally discharging vapor via the upper plate 2b, which comprises a porous body, and is molded into a predetermined shape due to the shape of the mold cavity 4, producing a required molded body 9.
