Summary: | The invention discloses a preparation method for preparing an environment-friendly adhesive by modifying urea-formaldehyde resin with aminated graphene. The preparation method comprises the followingsteps: preparing graphene oxide by a Hummers method, performing surface modification on the graphene oxide by a grafting method supplemented by an ultrasonic treatment method to prepare the aminated graphene, introducing the aminated graphene and tripolycyanamide in the process of preparing the urea-formaldehyde resin so as to control free formaldehyde in the urea-formaldehyde resin through a synergistic effect thereof, and preparing the environment-friendly urea-formaldehyde resin adhesive by using the aminated graphene as a formaldehyde trapping agent and a polycondensation reaction crosslinker at the same time. By the preparation method, a new thought and a new way are provided for design, synthesis and modification research of the urea-formaldehyde resin adhesive with low free formaldehyde content, and an impo |
