▎ 摘　　要

NOVELTY - Preparation of graphene oxide/titanium dioxide/zirconium dioxide composite material comprises taking natural graphite powder as raw material, oxidizing in the presence of concentrated sulfuric acid and potassium permanganate by Hummers oxidation, filtering, centrifuging, washing and vacuum drying to obtain graphene oxide sheets with thickness of 15 nm, adding in 20-80 ml water, ultrasonically processing at 180-450 W for 1 hour, preparing into graphene oxide suspension, adding zirconium oxychloride octahydrate, ultrasonically treating at 180-450 W for 0.5 hour, adding titanium dioxide nanopowder, stirring for 1 hour and conducting hydrothermal reaction to obtain the product. USE - Preparation of graphene oxide/titanium dioxide/zirconium dioxide composite material used for preparing textile finishing agent for use in far infrared finishing of textile i.e. cotton textile (all claimed). ADVANTAGE - The graphene oxide/titanium dioxide/zirconium dioxide composite material provides textile finishing agent, which improves the far infrared emission rate of fabric and has simple production and low cost. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) graphene oxide/titanium dioxide/zirconium dioxide composite material; and (2) preparation of textile finishing agent based on graphene oxide/titanium dioxide/zirconium dioxide composite material comprising taking graphene oxide/titanium dioxide/zirconium dioxide composite material, adding into 20-100 ml water, ultrasonically dispersing at 180-450 W for 2 hours, preparing graphene oxide/titanium dioxide/zirconium dioxide composite material dispersion liquid, mixing with aqueous polyurethane by vigorously stirring, and obtaining the product.
