Cellulose nanofiber-containing aqueous dispersion

Abstract

This invention relates to providing a resin composition and a resin molded article having sufficient mechanical properties and thermal properties, and also having excellent wear resistance and moldability when in use. This invention provides a cellulose nanofiber-containing aqueous dispersion including (A) cellulose nanofibers, (B) a surface treatment agent, and water. In one embodiment, (B) a surface treatment agent has an HLB value of 0.1 or greater but less than 8.0. This invention provides a dispersion liquid including (B) a surface treatment agent, (D) a binder component, and water, wherein (B) the surface treatment agent is a water-soluble polymer having a hydrophilic segment and a hydrophobic segment, and having a number average molecular weight of 200 to 30,000, and (D) the binder component is polyurethane. This invention provides a cellulose nanofiber resin composition including (A) cellulose nanofibers, (B) a surface treatment agent, and (F) a thermoplastic resin.
