  • Resin molded body production method
    Patent number: 11572447
    Abstract: Provided is a resin molded body production method that enables production of a resin molded body in which mechanical strength is good, anisotropy of physical properties is low, and little warpage is developed. This production method is for a resin molded body containing a thermoplastic resin (A) and a cellulose nanofiber (B), the production method including: a step for preparing a main supply material (a1) containing the thermoplastic resin (A) and the cellulose nanofiber (B) and an auxiliary supply material (a2) that is a product of melting treatment of the main supply material (a1); a resin composition formation step for obtaining a resin composition (b) by melting and mixing of the main supply material (a1) and the auxiliary supply material (a2); and a step for obtaining the resin molded body by molding the resin composition (b).
