A method for preparing a phenol-formaldehyde resin is provided. The method includes extracting a biomass pyrolysis oil to obtain a first phenolic mixture, and polymerizing the first phenolic mixture to form a phenol-formaldehyde resin solution under an aldehyde, an alcohol and an alkaline catalyst. The disclosure also provides a resin material prepared from the phenol-formaldehyde resin. The disclosure further provides a method for preparing a resin molding material.
