NOVELTY - Preparing graphene cement additive, comprises (1) adding graphene powder, cement, anhydrite, dendritic polyamidoamine, cement adhesive and slag micropowder into mixing mixer for heating, mixing and stirring, uniformly adding water, adding cement anti-seepage water-repellent, dendrimer polyamide amine, water reducing agent, defoamer, surfactant and inorganic salt, and uniformly stirring to obtain mixed slurry; (2) placing the mixed slurry in evaporation chamber to complete water evaporation work, forming slimy slurry, placing slimy slurry into the extruder, drying cut and shaped pulp in dryer, placing dried slurry into crushing device, passing through the crushing device to complete the crushing and grinding work, and completing powder filtration work through filter; and (3) placing storage box filled with filtered additive powder on packaging machine, stacking the packaging boxes and storing them in the dry storage room. USE - The method is useful for preparing graphene cement additive. ADVANTAGE - The method improves the filtering effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation device for graphene cement additive.
