Title:
POLYURETHANE RESIN COMPOSITION AND PROCESS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2017/126566
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a polyurethane resin composition having satisfactory strength, heat resistance, and water resistance and a process for producing the polyurethane resin composition. The polyurethane resin composition comprises a polyurethane resin and cellulose nanofibers that are fine fibers (average fiber diameter; about 3-500 nm) of unmodified cellulose or chemically modified cellulose, the content of the cellulose nanofibers being 0.1-10 parts by mass per 100 parts by mass of the polyurethane resin. Thus, the excellent effects are exhibited.
