The invention relates to a method for preparing graft modification protein adhesives, belonging to the adhesive technical field. The method obtains the graft modification protein adhesives by adopting redox system initiator to react for a period of time at a certain temperature and linking vinyl monomer branched chains on a protein trunk chain. During the production and use processes, substances such as formaldehydes and so on are not released, thereby the method is favorable for environmental protection; and simultaneously the method can increase the added value of protein products and has important economic value.
