The invention provides a method for preparing a graphene epoxy resin dispersion, comprising the following steps: firstly, after stirring and mixing graphene and an organic solvent, a graphene mixture is obtained; After the acid salt surfactant and the Tween surfactant are stirred and mixed again, a graphene dispersion is obtained; finally, an epoxy resin is added to the graphene dispersion obtained in the above steps, and after stirring and mixing for the third time, After grinding, a graphene epoxy resin dispersion is obtained. The invention changes the adding method of graphene-based materials, firstly obtains graphene epoxy resin dispersion, solves the problem of graphene dispersion well, ensures the perfect display of its excellent performance, and adopts post-coating additives, so as to avoid It is necessary to add excess additives to reduce the introduction of impurities, and the whole process is carried out at room temperature, which abandons the traditional ultrasonic dispersion, effectively reduces energy consumption, and is more conducive to industrialized large-scale production. |
