NOVELTY - Preparation of graphene oxide-phenolic resin composite material involves: (1) adding graphene oxide, hydrazine hydrate, surfactant and aldehyde to a reactor, stirring and heating to a temperature of 80-100 degrees C; and (2) cooling reaction liquid to 60-80 degrees C, regulating pH to 1.5-4.5, adding acidic catalyst and phenol, raising temperature to 85-100 degrees C, and dehydrating to obtain a composite material containing graphene oxide, hydrazine hydrate, surfactant, aldehyde and phenol in a ratio of (1-10):(1-5):(3-20):(110-160):600. USE - Graphene oxide-phenolic resin material is used in electric wood powder (claimed). ADVANTAGE - The graphene oxide-phenolic resin material provides high impact strength and low molding shrinkage property to electric wood powder. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for usage method of graphene oxide-phenolic resin material in electric wood powder.
