Beschreibung
Zusammenfassung:The invention discloses a preparation method of graphene modified phenolic resin, and the preparation method is as follows: A) phenol, formaldehyde and an alkaline catalyst are mixed for reaction to obtain phenolic resin; and B) the phenolic resin obtained by the step A) and graphene are mixed for reaction to obtain the graphene modified phenolic resin. According to the method, the graphene is used for modifying the phenolic resin, the strength and conductivity properties of the phenolic resin are greatly improved, the impact strength of the cured phenolic resin is increased by more than 60%, the flexural strength is increased by more than 40%, the cured phenolic resin is endowed with conductive properties, the application field of the phenolic resin is expanded, and the method has the advantages of simple operation and easy industrialized production.
